Why I Wrote This Guide
I've spent over two decades originating real estate financing in California — the last eleven years as a licensed broker, the years before that as a salesperson. Most of the transactions that reach me share a common pattern: they sit in a handful of ZIP codes where conventional bank financing either doesn't fit the buyer's situation or doesn't move at the speed the deal requires. Fisher Island. Atherton. Sagaponack. Newport Beach. Greenwich. Aspen.
This guide walks through the 50 most expensive ZIP codes in the United States — using PropertyShark's October 2025 published data, not estimates — and explains where private money lending actually fits in each one. For each market I've included what's happening on the ground and how I'd typically structure a loan there. The numbers in the table below come straight from PropertyShark's closed-sale records, which is what makes this ranking more useful than the listing-price 'most expensive' lists that circulate every year.
If your deal is on this list, the rest of this guide will be useful. If it isn't, the patterns usually still apply — call me anyway.
About Kevin Morris Green
I'm a licensed California Real Estate Broker (DRE #01241542, active and in good standing since 2014) and a federally registered Mortgage Loan Originator (NMLS ID #1130752). My primary office is in Truckee, California, and I've been originating real estate financing for over 25 years — the first part of my career as a salesperson, then as a broker since 2014.
My focus is private money lending for trophy-property transactions — bridge loans, ground-up construction loans, value-add renovation financing, and developer acquisition loans. Typical loan sizes run from $1 million on the low end to $50 million-plus at the top, with the bulk of activity in the $3 million to $25 million range. Closings are typically structured in 7 to 21 days, with underwriting based on the property and the deal structure rather than the borrower's W-2 income.
Most of my business comes from referrals — luxury brokers whose deals are stalled at a conventional lender, estate trustees with timing pressure, family offices reorganizing capital structures, and developers who need site control before institutional debt is ready to engage.

What's Happening in These Markets
Region by region, with the financing realities I see in each. The market notes draw on PropertyShark's published commentary, news coverage of specific transactions, and patterns from the deals I structure. Everything below has been cross-checked against the PropertyShark 2025 report and other sources cited inline.
Florida
Florida has only two ZIPs in the national top fifty — but one of them, Fisher Island, now sits at the top of the entire country.
Fisher Island, Miami Beach — ZIP 33109 (#1, $9.5M median)
Fisher Island's 2025 median of $9.5 million made it the most expensive ZIP in the United States, ending Atherton's eight-year run at #1. PropertyShark attributes a 65% year-over-year price jump to a wave of luxury-condo sales. The cheapest 2025 transaction on Fisher Island still closed at $1.41 million; the most expensive — a 6,800-square-foot, three-bedroom condominium — sold for $23.7 million.
The island has no bridges. Access is by private ferry, boat, or helicopter. Residential supply is limited and tightly controlled by the Fisher Island Club. From a financing standpoint, that scarcity is the deal: comparables are thin, appraisals take effort, and most purchases route through offshore LLCs or layered trust structures that institutional lenders won't underwrite. Club approval timelines add 60-to-90-day windows that don't align with conventional mortgage processing. Bridge financing here is usually about giving the buyer the ability to close on the seller's timeline and refinance into long-term capital after approval and appraisal complete.
Boca Grande / Gasparilla Island — ZIP 33921 (#24, $3.49M median)
Gasparilla's southern half — Boca Grande, the Gasparilla Inn, the tarpon tradition — has long pulled old Midwest and Northeast money to Southwest Florida. The transactions are quieter than Miami's, the buyers are typically multi-generational, and renovation lending (vs. fresh acquisition) is a bigger share of what I see here.
California
California claims eight of the ten most expensive ZIPs in the country and roughly 30 of the top 50. Per PropertyShark, the state holds 61% of the entire top 100. The Silicon Valley corridor — Atherton, Los Altos, Portola Valley, Palo Alto, Menlo Park, Saratoga, Cupertino — drives a wide swath of the table. Greater Los Angeles contributes Beverly Hills, Bel Air/Holmby Hills, Brentwood, San Marino, Manhattan Beach, and the Pacific Palisades. Orange County's coast is anchored by Newport Beach, which is now officially the most expensive city in the United States.
KEY FACT · Newport Beach holds three of the top 10 ZIPs and is one of only two U.S. cities where every residential ZIP makes the national top 100. The other is Greenwich, Connecticut. |
Atherton — ZIP 94027 (#2, $8.333M median)
Atherton held the #1 spot in the country for eight consecutive years until Fisher Island overtook it in 2025. It remains the de facto capital of Silicon Valley residential wealth — founders, partners at the Sand Hill venture funds, and a steady rotation of technology CEOs buying through revocable trusts and family LLCs. PropertyShark reports a 5% YoY gain to a record $8.333 million; the cheapest Atherton transaction was $3.2 million, the most expensive a $51.5 million, 10,000-square-foot home purchased by tech CEO Stephen Luczo (per Real Deal SF, April 29, 2025).
Atherton deals share a few patterns: 1031-exchange timing pressure on the seller side, trust-based entity structures on the buyer side, and a strong preference for off-market transactions where the lender has to move at the same speed as a cash buyer.
Newport Beach — ZIPs 92661, 92657, 92662, 92625, 92663, 92660 (six top-100 ZIPs)
Per PropertyShark, every one of Newport Beach's six residential ZIPs sits in the national top 100. Three are in the top 10: Balboa Peninsula (92661, #4), Newport Coast (92657, #8), and Balboa Island (92662, #9 tie). Corona del Mar (92625) holds #17. The remaining two (92663, 92660) round out the city's footprint at #30 and #33. Acquisition and construction lending dominate my activity here, often for fix-and-hold investors repositioning waterfront properties.
Montecito / Santa Barbara — ZIP 93108 (#6, $5.24M median)
Montecito's buyer base — Oprah Winfrey, the Sussexes, Ellen DeGeneres, and a long list of tech and entertainment principals — values privacy and speed roughly equally. Inventory is tight by design; estates often trade without ever being listed. Most Montecito loans I structure are short-duration bridges sized to let a buyer move before a competing bid forms, then refinance into longer-term private debt after close.
Stinson Beach — ZIP 94970 (#7, $5.225M median)
PropertyShark recorded a 38% one-year price jump in Stinson Beach in 2025 — pushing the median above $5 million for the first time and putting Marin County's coast in the top 10 for only the second time (the first was 2023). The buyers are mostly Bay Area technology wealth looking for a coastal contrast to Silicon Valley. Construction lending is the larger half of my activity here — the lots are dramatic and most buyers want to renovate heavily after they close.
Los Altos & Los Altos Hills — ZIPs 94022 (#9), 94024 (#14)
Per PropertyShark, Los Altos crossed the $5 million median line for the first time in 2025, tying with Balboa Island at #9. Los Altos Hills holds #14 at $4.268 million. The combined corridor is where a lot of Silicon Valley's mid-tier trophy market lives — meaningful estates without the Atherton sticker. Acquisitions here often run through founder-controlled LLCs or estate-planning trusts.
Rancho Santa Fe — ZIP 92067 (#10, $4.995M median)
San Diego County's most prestigious enclave — a deed-restricted community governed by the Rancho Santa Fe Association's architectural review. The covenants slow everything down, which is exactly why bridge capital matters: buyers need to close first and work through the review process from a position of ownership.
Santa Monica (North of Montana) — ZIP 90402 (#11, $4.863M median)
The Riviera section of Santa Monica — north of Montana, walkable to the beach, estate-scale homes on R1 lots. A steady stream of trust and LLC purchases, especially from out-of-state and international buyers establishing a Los Angeles presence.
Beverly Hills — ZIP 90210 (#13, $4.35M median)
The most-recognized residential ZIP in the world. PropertyShark also separately ranks 90212 (#56) and 90211 (#66), giving Beverly Hills three top-100 ZIPs. The bulk of the private-lending activity in 90210 happens in the $5M-to-$25M range — entity-owned acquisitions, post-divorce buyouts, and developer flips on tear-down lots. The headline-grabbing $100M+ transactions exist, but they're a small slice of actual deal flow.
Palo Alto & Portola Valley — ZIPs 94301 (#15), 94028 (#15), 94306 (#34)
Palo Alto is Stanford, Sand Hill, and Old Palo Alto's $5M+ estate streets — split between 94301 ($4.2M median) and 94306 ($3.1M median). Portola Valley sits a few miles up into the hills — semi-rural, large lots, a lot of horse properties and contemporary estates. Both markets get hit hard with founder-LLC acquisitions and renovation lending. Portola Valley construction loans tend to be longer-duration than the Bay Area average because of the site work involved.
Bel Air / Holmby Hills & Brentwood — ZIPs 90077 (#22), 90049 (#31)
Bel Air and Holmby Hills round out LA's Platinum Triangle alongside Beverly Hills. PropertyShark notes 90077 was up 25% year-over-year to a $3.55 million median — its best position yet. Brentwood (90049) sits a step down at $3.165 million. Spec development is a meaningful share of activity in both ZIPs; construction financing is typically draw-based with interest reserves built in and a clear exit to either a sale or long-term debt at completion.
Belvedere / Tiburon — ZIP 94920 (#23, $3.5M median)
Belvedere Island and Tiburon offer one of the most scenically dramatic residential settings on the West Coast — a promontory in San Francisco Bay with Golden Gate and Mount Tamalpais views. Bridge financing here often serves estate-sale and divorce-settlement timing.
Manhattan Beach & Hermosa Beach — ZIPs 90266 (#27), 90254 (#55)
The South Bay's two coastal trophy markets — Manhattan Beach in the top 30 nationally, Hermosa Beach a step down. Construction and renovation lending dominate here, particularly the South Bay's recurring teardown-and-rebuild rhythm.
Pacific Palisades — ZIP 90272 (#59, $2.525M median)
PropertyShark reports the 2025 wildfires drove the Palisades' median down 20% year-over-year to $2.525 million. Inventory shifted, pricing moved, and a value-add window opened for investors with private capital who can move before institutional lenders re-engage. Rebuild financing on damaged lots and bridge acquisitions on under-priced parcels are the two scenarios I'm actively underwriting in this ZIP.
Laguna Beach — ZIP 92651 (#45, $2.743M median)
The artistic, cove-and-canyon end of the Southern California coast. Clifftop and oceanfront estates trade across a wide range; I see a meaningful share of construction loans here because the lots are often non-conforming and the renovation scope can outrun a conventional rehab loan.
Other California markets in the top 50
Saratoga (95070, #19), Hillsborough/Burlingame (94010, #21), Diablo (94528, #23), Big Sur (93920, #23), Ross (94957, #25), Los Gatos (95030, #28), San Marino (91108, #35), Carmel by the Sea (93921, #37), Menlo Park (94025, #38), Sunnyvale (94087, #41), Stanford (94305, #42), Cupertino (95014, #44), Del Mar (92014, #47), Redwood City (94062, #49). Each is a distinct private-lending market — different buyer profile, different deal cadence — but the same fundamental pattern: speed and structure matter more than rate.
New York
PropertyShark calls 2025 one of New York's weakest showings in a decade — 15 ZIPs in the national top 100, with only three of those inside NYC. The Hamptons remain the state's luxury anchor: nine Suffolk County ZIPs make the top 100, including two in the top 10 (Sagaponack at #3, Water Mill at #5).
Sagaponack — ZIP 11962 (#3, $5.925M median)
Per PropertyShark, Sagaponack has been New York State's most expensive ZIP for ten consecutive years — a remarkable streak. Hedge fund principals, private equity partners, and entertainment industry families have built the Sagaponack ownership base. The financing constraints are typical for the Hamptons: short selling windows, competitive off-market situations, and entity-structured buyers. That's where a private bridge with 10-to-14-day execution wins the deal.
Water Mill — ZIP 11976 (#5, $5.5M median)
Water Mill is Sagaponack's western neighbor and the Hamptons' second-most-prestigious address. PropertyShark notes the 2025 median slipped 6% year-over-year but remains more than double its 2016 level. Most of the financing I structure here is acquisition-side bridge for buyers competing against cash.
Wainscott — ZIP 11975 (#12, $4.5M median)
Wainscott sits between Sagaponack and East Hampton — quieter than its neighbors, with renovation activity making up a larger share of volume than fresh acquisitions.
TriBeCa & Surrounds — ZIPs 10013 (#20), 10007 (#29), 10012 (#52)
TriBeCa's 10013 remains Manhattan's most expensive residential ZIP at $3.7 million — though down from its 2017 peak when it was the country's #2 ZIP at $4.1 million. Adjacent FiDi/SoHo (10007, #29) and NoLita/SoHo (10012, #52) round out NYC's three top-100 ZIPs. Most of my Manhattan activity is bridge financing for LLC-owned purchases — co-op and condo board approval timelines make this a market where private capital is often the only practical path to close.
Amagansett — ZIP 11930 (#36, $2.998M median)
Amagansett is the last Hamptons outpost before East Hampton's Northwest Woods and Montauk — surfers, artists, and billionaires in unusually close proximity. The inventory ranges from historic farmhouses to contemporary oceanfront builds.
Bridgehampton — ZIP 11932 (#39, $2.875M median)
Bridgehampton anchors the social middle of the Hamptons — the Polo Club, recognizable oceanfront estates, and a high concentration of permanent-resident hedge fund and PE money. Bridge financing demand tracks the broader Hamptons rhythm: heavy in spring and early summer, more renovation-and-refi work in winter.
Old Westbury & Quogue — ZIPs 11568 (#40), 11959 (#46)
Old Westbury (Nassau County) and Quogue (Suffolk County) round out the New York state top 50, both in the high-$2-million range. Old Westbury's estate streets and Quogue's village-to-bay corridor each have their own financing rhythms.
New Jersey
New Jersey's luxury market concentrates in Bergen County (Alpine), the Jersey Shore's Monmouth County (Deal, Allenhurst), and Essex County's Short Hills corridor.
Alpine — ZIP 07620 (#13, $4.35M median)
Alpine is a fortress of American wealth — Bergen County, multi-acre lots, fortified estate properties, historically tied to hip-hop, finance, and pro sports money. PropertyShark notes Alpine has been New Jersey's most expensive ZIP for nine of the last ten years (briefly overtaken once by Deal). The 2025 median jumped 31% year-over-year to $4.35 million. Entity- and trust-based purchases dominate.
Deal — ZIP 07723 (#22, $3.55M median)
Deal is New Jersey's most distinctive luxury market — oceanfront Victorians and Mediterranean estates, historically tied to the Orthodox Jewish community and now expanding into broader New York financial-industry buyers. PropertyShark recorded a 20% year-over-year increase to $3.55 million.
Short Hills — ZIP 07078 (#69, $2.415M median)
Short Hills (Millburn Township) is New Jersey's most prestigious inland address — large Tudor and Colonial estates favored by Wall Street executives who want New York access with suburban privacy. Outside the top 50 nationally but consistently in the top 100, and a real market for private lending.
Connecticut & New England
Per PropertyShark, Connecticut had its strongest year in a decade in 2025 — a record seven top-100 ZIPs, surpassing Massachusetts for the first time. Greenwich tied Los Angeles as the country's second-most-expensive city by ZIP count, with all four residential Greenwich ZIPs in the national top 100 — same distinction as Newport Beach.
Greenwich — ZIPs 06878 (#43), 06870 (#50), 06831 (#58), 06830 (#83)
Greenwich is Wall Street's residential backyard — managing directors, fund founders, and family-office principals have lived here for generations. Riverside (06878) leads at $2.753 million; Old Greenwich (06870) is right behind at $2.65 million. Back Country (06831, $2.535 million) is the rolling estate land at the northern end of town. Every Greenwich residential ZIP makes the national top 100 — one of only two U.S. cities where that's true.
Other Fairfield County: Darien (#73), New Canaan (#96), Norwalk (#98)
Connecticut's top-100 presence isn't just Greenwich — Darien (06820), New Canaan (06840), and Norwalk's Rowayton (06853) all sit in the top 100. The pattern of Wall Street commuter wealth extends through the entire Fairfield County coast.
Boston Back Bay — ZIP 02199 (#54, $2.573M median)
Boston's Back Bay was the country's #2 most expensive ZIP in 2021 at a $5.5 million median. PropertyShark notes its 2025 ranking of #54 is its lowest in a decade. The luxury condo and townhouse market here remains active, with most private lending activity in the $3M-to-$15M range.
Nantucket — ZIP 02554 (#63, $2.498M median)
PropertyShark notes Nantucket's median fell from $2.9 million in 2024 to just under $2.5 million in 2025 — a softening year, though the structural drivers haven't changed. Historic preservation, seasonal scarcity, and the logistical complexity of island construction still make private lending the pragmatic option for both acquisition and renovation. The construction window is short, the material logistics are complicated, and most of my Nantucket loans build the timing constraints directly into the draw schedule.
Chilmark, Martha's Vineyard — ZIP 02535 (#64, $2.475M median)
Chilmark — the Vineyard's most private, topographically dramatic section. The remoteness drives construction cost and timeline; private financing is what makes most of these projects pencil.
New Castle, NH — ZIP 03854 (#50, $2.65M median)
PropertyShark notes 2025 was the first year New Hampshire's most expensive ZIP (New Castle) was pricier than Massachusetts' leading ZIP. New Castle is a small island in Portsmouth Harbor; most buyers are Boston- or New York-based.
Weston, MA — ZIP 02493 (#72, $2.393M median)
Weston is metro Boston's leading suburban luxury address — large Tudor and Colonial estates on wooded lots, a longstanding favorite of Boston financial executives.
Southeast & Mid-Atlantic
Sea Island, GA — ZIP 31561 (#15, $4.2M median)
Sea Island is one of the most extraordinary private resort and residential communities in the country — The Cloister, the Sea Island Golf Club (host of the PGA Tour's annual season finale), and a controlled-access development governed by the Sea Island Company. The buyer base is heavily corporate-executive and old-money Southern. Most lending here is acquisition and renovation; new construction is tightly controlled.
Sullivan's Island, SC — ZIP 29482 (#18, $3.95M median)
Sullivan's Island sits at the mouth of Charleston Harbor — barrier-island trophy homes within minutes of downtown Charleston. The historic preservation overlay limits new builds, so most activity here is acquisition + renovation bridge.
Gibson Island, MD — ZIP 21056 (#32, $3.15M median)
Gibson Island is the East Coast's least-known great island community — gated, served by a single causeway and a private ferry, with its own club, police force, and yacht club. Roughly 200 homes total. The Mid-Atlantic's quiet equivalent of Fisher Island.
Western Markets — Mountain, Desert, Pacific
Beyond California, the western luxury map runs from Paradise Valley in Arizona through Aspen and Snowmass in Colorado, the Nevada side of Lake Tahoe, the Seattle lake communities (Medina and Mercer Island), and into Hawaii's north shore of Kauai.
Medina, WA — ZIP 98039 (#16, $4.15M median)
Medina is the Pacific Northwest's most exclusive residential community — a small lakefront city directly across Lake Washington from Seattle, historically home to Bill Gates and Jeff Bezos among other Pacific Northwest technology principals. PropertyShark notes 2025 was Medina's tenth consecutive year among the country's priciest ZIPs. Estate lots are large, waterfront, and increasingly transacted through revocable trusts and family LLCs.
Paradise Valley, AZ — ZIP 85253 (#23, $3.5M median)
Paradise Valley is the most prestigious residential municipality in the Southwest — an entirely residential city set between Scottsdale and Phoenix with views of Camelback and Mummy Mountain. PropertyShark notes 2025 was Paradise Valley's seventh consecutive year as Arizona's most expensive ZIP and an 8% YoY gain to a record $3.5 million median. Construction lending is a meaningful share of activity.
Glenbrook & Crystal Bay, Lake Tahoe, NV — ZIPs 89413 (#26), 89402 (#48)
PropertyShark notes 2025 was the first year since 2021 that Nevada placed two ZIPs in the national top 100. Glenbrook ($3.4 million median) and Crystal Bay ($2.7 million) both set new records. Lakefront splendor, Sierra setting, no Nevada income tax, and Bay Area proximity drive the buyer base.
Aspen & Snowmass Village, CO — ZIPs 81611 (#42), 81654 (#67)
Aspen is America's most elite mountain resort, with Snowmass adjacent and slightly quieter. Construction loans here are draw-based, season-aware, and almost always structured around a clear exit to either a sale or long-term private debt.
Mercer Island, WA — ZIP 98040 (#78, $2.31M median)
Mercer Island sits in the middle of Lake Washington between Seattle and the Eastside — bridge-accessed, exclusive, and increasingly favored by tech executives who want island privacy without a ferry.
Kilauea / Kauai, HI — ZIP 96754 (#62, $2.5M median)
Kauai's north shore — Kilauea, Kalihiwai, Anini, and some of the most dramatic oceanfront in the Pacific. Strict land-use limits and limited developable coastline guarantee permanent scarcity. Most of my Kauai activity is acquisition and construction financing for buyers structuring purchases through entities.
Why Private Lending Is the Default in These Markets
Five fundamentals show up in every market on this list, and they're the reason private capital — not conventional bank debt — closes the meaningful share of transactions here.
1. Speed matches the way these deals actually trade
The best opportunities close in days, not months. Off-market estates. Pre-construction allocations. Estate-sale timing pressure. Sellers who'd rather take certainty than the highest bid. My typical close is 7 to 21 days, depending on title clarity, valuation status, and entity documentation. Conventional bank financing on a trophy property typically runs 60 to 90 days. The gap is usually the deal.
2. Underwriting fits how the wealth is actually held
The buyers in these ZIPs aren't W-2 employees. They're fund managers, founders, family-office principals, international heirs, and PE partners whose net worth lives inside LLCs, holding companies, and irrevocable trusts. Banks underwrite the borrower. Private money underwrites the asset and the deal structure. That's the framework that fits the actual buyer profile in these markets.
3. Construction expertise where it matters
Many of the country's significant trophy-property development opportunities are concentrated in these 50 ZIPs — luxury estate builds in Portola Valley, boutique condo work in TriBeCa, resort-grade hospitality projects in Aspen and Kauai. Draw-based construction loans with interest reserves built in and exit strategies matched to the actual project timeline.
4. Discretion that matches the asset
Ultra-trophy transactions require private-banking-grade confidentiality. Entity- and trust-based purchase structures, discreet referral handling, no public marketing of specific deals or borrowers.
5. One lender across multiple markets (where the regulatory framework allows)
A family office or multi-market investor can work one private-lending relationship across an entire portfolio. California transactions are directly originated under my California Real Estate Broker license. Out-of-state transactions are structured through licensed partner lenders where required by applicable state law. The consistent underwriting framework stays the same; the regulatory path adapts to the transaction's location.
The Private Money Lending Loans I Structure
Private bridge loans — $1M to $50M+
Fast-closing, asset-backed acquisition and refinance loans for trophy properties. Interest-only payments. Entity and trust borrowers welcome. Typical close in 7 to 21 days. Built for off-market acquisitions, competitive bid situations, estate-settlement purchases, and buyers transitioning from a stalled conventional process to private financing.
Construction loans — ground-up and value-add
Draw-based construction financing for luxury estate builds, boutique condo development, hotel-to-condo conversions, and major renovation projects. Each loan is structured around the specific project timeline, pre-sale assumptions, and exit strategy. Interest reserves available.
Commercial real estate loans — investment & income property
For investors building trophy portfolios — luxury rentals, mixed-use assets, boutique hospitality, condo-hotel interests. Flexible structures including cross-collateralization, blanket portfolio loans, and equity participation where it makes sense.
Developer acquisition & land financing
Site-acquisition loans for luxury developers locking up trophy parcels. Asset-based underwriting on development potential rather than current income.
Who I'm Not the Right Fit For
I don't write conforming mortgages for owner-occupied primary residences where a 30-year fixed makes more sense. I don't fund speculative land deals with no identifiable exit. I don't compete on rate against bank financing when the buyer has time, clean documentation, and the deal can wait 90 days. If that describes your situation, your bank will serve you better, and I'll say so on the call.
Frequently Asked Questions
How fast can you actually close?
Standard close is 7 to 21 days from the day we agree on terms. For straightforward single-asset bridge transactions with clean title and a current valuation, 10 days is achievable. Construction loans take longer because the draw schedule and budget review add structure work. All timelines are subject to underwriting, third-party reports, and title clearance.
What loan sizes do you fund?
$1M on the low end, $50M+ at the top. The bulk of activity sits in the $3M-to-$25M range. For loans above $20M I'll typically syndicate a portion of the capital, but the underwriting decision and the close stay with me as the direct lender.
What's a typical interest rate?
Private bridge rates currently run roughly 9% to 12% depending on loan-to-value, property type, market, term length, and exit certainty. Construction loans price above that. Every deal is quoted individually because no two trophy-property transactions carry the same risk profile. Specific rates depend on current market conditions, borrower profile, and deal structure.
Do you require tax returns and full income documentation?
No. The underwriting is asset-based. I'm focused on the property's value, the deal structure, and the exit. I'll usually ask for a simple sources-and-uses, the purchase contract or refi payoff, and any existing appraisal or valuation work — not your personal tax returns.
Can you lend to an LLC, trust, or foreign-national entity?
Yes. Most of my borrowers close through LLCs, irrevocable trusts, family-office holding companies, or offshore structures.
Where do you lend?
California transactions are directly originated under my CA DRE Broker license (#01241542). Transactions outside California are structured through licensed partner lenders where required by applicable state law.
