Super Jumbo DSCR Loans In Tiburon — The Quick Read: These loans qualify on the rental income the property produces, not the investor’s traditional personal-income documentation. At Tiburon price points, that number matters more than almost anything else in the file, because the home’s value sits well above conforming limits and the rent has to justify a much larger loan amount. Leverage steps down as the loan size climbs, coverage of 1.00 earns the best terms available, and appraisal-based rent conclusions can swing the whole deal. This is a property-income underwrite, not a personal-income one, subject to lender guidelines.
What “Super Jumbo” Actually Means Here
There’s no government agency that defines “super jumbo.” The Federal Housing Finance Agency sets conforming loan limits every year, and in high-cost counties — Marin County, where Tiburon sits, is one of them — that ceiling runs higher than the rest of the country, per the Fannie Mae Single Family Loan Limits page. Anything above that ceiling becomes jumbo in the conventional world. Non-QM lenders then draw their own line for “super jumbo,” and it moves lender to lender.

Across the wholesale lending network Lendmire works with, super jumbo DSCR financing runs from $150,000 up to $10,000,000. The standard DSCR program most lenders offer stops around $3,000,000. This ladder is built to carry qualified investors past that ceiling into true luxury-property territory, subject to underwriting on every file.
Key Terms Defined
DSCR (debt service coverage ratio): the monthly rent divided by the full monthly housing payment — principal, interest, taxes, insurance, and HOA dues if applicable. A ratio of 1.00 means rent covers the payment exactly.
PITIA: the full monthly obligation lenders measure rent against — principal, interest, taxes, insurance, and association dues.
Business-purpose loan: a loan made to an investor buying or refinancing a rental, not a home to live in. Because it’s business-purpose, it’s reviewed differently from an owner-occupied mortgage.
Non-warrantable condo: a condo that doesn’t meet standard agency eligibility rules — common in resort and luxury markets — and financed through separate, often lower-leverage guidelines.
How Underwriting Actually Treats These Files
The property gets underwritten, not the person. Lenders don’t ask for W-2s or two years of traditional personal-income documentation. They ask: does the rent cover the payment? That’s the whole engine behind DSCR lending, and Lendmire’s complete DSCR loans guide walks through the mechanics in full.
Step one is establishing what the property can actually rent for. Appraisers use a standardized rent schedule — Fannie Mae’s Form 1007 for single-unit properties, Form 1025 for two-to-four unit buildings — to document market rent, even though DSCR lenders aren’t bound by Fannie Mae’s own selling guide when they use these forms.
Step two is verification. If the property is occupied, a signed lease supports the number. If it’s vacant, the appraiser’s rent opinion carries the whole weight of the calculation — there’s no lease to check it against. Most programs in the network default to whichever figure is lower, the lease or the appraisal, as a conservative check against an inflated rent claim.
Step three is the math itself: rent divided by PITIA. In a market where property taxes and insurance run heavier than the national norm, that denominator gets bigger at the same loan amount — which means the same rent produces a tighter coverage number than it would somewhere with a lighter tax and insurance load. This is the quiet reason luxury-market DSCR files feel harder to clear than the loan amount alone would suggest.
Step four is leverage. Coverage at 1.00 or better earns the strongest terms a program offers. Below that, some lenders in the network still work with the file — but leverage and terms adjust, subject to underwriting, and this path only reaches up to $2,000,000 in loan size.
The Leverage Ladder, Size By Size
Leverage steps down as the loan gets bigger — that’s the core structural fact of super jumbo DSCR lending, and it surprises investors who assume one flat percentage applies across the board.
| Loan Amount | Purchase | Rate-Term Refi | Cash-Out | Credit Floor |
|---|---|---|---|---|
| $150K–$1M | 80% | 80% | 75% | 660+ |
| $1M–$1.5M | 75% | 75% | 70% | 700+ |
| $1.5M–$2M | 75% | 75% | 60% | 720+ |
| $2M–$3M | 75% | 75% | 60% | 720+ |
| $3M–$4M | 65% | 65% | none | 700+ |
| $4M–$6M | 60% (on review) | 60% (on review) | none | 700+ |
| $6M–$10M | 60% (on review) | 60% (on review) | none | 700+ |
Every cell above the $1,000,000 mark is a ceiling, not a promise — and above $4,000,000, every request gets reviewed case by case before it’s even submitted, purchase or rate-and-term only. There’s no cash-out above $3,000,000 anywhere on this ladder. Cash-out itself runs unlimited proceeds at or below 60% LTV, with a $1,500,000 cap above that line — and for short-term-rental collateral specifically, that cash-out ceiling tightens to 70% rather than the 75% standard-rental figure, in the same breath every time it’s discussed. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Credit requirements climb with loan size too. The 660 floor at entry-level pricing becomes 700 above $3,000,000, paired with a clean 48-month event history and no more than one 30-day late payment in the trailing 24 months (0x30x24). Above $2,000,000, two separate appraisals are required rather than one — a direct response to how much a single appraised-value opinion can swing both the LTV math and the rent-to-PITIA math at that size.
Reserves, Occupancy, and the Interest-Only Option
Reserves run six months of PITIA on the subject property for most borrowers — or ITIA if the loan carries interest-only payments — climbing to twelve months for a first-time investor. Reserves on other financed properties aren’t required beyond that, even for investors carrying up to 20 financed properties in their portfolio.
Interest-only structuring is available for up to 120 months on 30- and 40-year terms, capped at 75% loan-to-value, with a coverage floor of 0.75 or better and qualification run on the ITIA payment rather than the fully amortizing one. For an investor carrying a large loan balance against a high-value rental, that interest-only runway can be the difference between a file that clears comfortably and one that’s borderline.
Non-warrantable condos — common in resort and coastal luxury markets — are financed to 75% and capped at $1,500,000 in this program. Condotels go to 75% on a purchase, 65% on a refinance, capped at $1,500,000, with $250,000 in cash-in-hand required from the borrower.
Where the General Rule Breaks
Vacant properties and new construction. With no lease in place, the entire DSCR number rests on the appraiser’s market-rent opinion. That raises the stakes on comparable selection significantly, since there’s nothing to check the number against.
Short-term rentals. The standard rent-schedule form is built around monthly lease comparables, not nightly rates — Fannie Mae has flagged it as an outright error for an appraiser to multiply a nightly rate by 30 to fabricate a monthly figure. In the network, short-term-rental files instead qualify on twelve months of documented operating history on a refinance, or the appraisal’s dedicated short-term-rent analysis on a purchase — at 80% of gross income, and only for experienced investors with at least twelve months owning income property in the last three years. These files cap at $2,000,000 and require coverage of 1.00 or better; they’re not eligible on the no-ratio path. Municipal permission to operate short-term rentals is never assumed — it has to be documented for the specific property, because short-term rental rules can vary by city, county, HOA, and property type.
Rural, unusual, or comp-thin properties. The whole rent-schedule methodology assumes a liquid local rental market full of comparable properties to draw from. Rural parcels, unusual architecture, or a thin comp set can complicate that process. Rural land is workable to five acres at 75% LTV, twenty acres up to $3,000,000, ten acres above that threshold. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
DSCR vs. conventional financing
Two common ways to finance an investment property in this market. They qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
No-ratio files. A handful of lenders in the network will consider a no-ratio structure — no DSCR calculated at all — up to $2,000,000, but only with a seven-year clean housing payment history and 0x30x24 credit, subject to underwriting. No minimum ratio is published for this path because none is required; it’s evaluated entirely on credit depth and reserves instead.
Trade coverage of the broader non-QM market confirms this segment keeps growing because the gap between agency and private-capital financing keeps widening, per Scotsman Guide’s reporting on investor-owned homes — and most of that growth is coming from small-portfolio investors, not institutional buyers.
What This Looks Like In A High-Value Market
Home values in Tiburon run well above the national median — Zillow’s home value data for Tiburon places typical values in the low-$3-million range. At that price tier, PITIA is large no matter how strong the local rent market is, which means achievable market rent becomes the single biggest lever in whether a file clears at standard leverage or needs a reduced-leverage, no-ratio, or added-reserves structure instead. A modest difference in the appraiser’s rent conclusion can be the difference between a deal that clears comfortably and one that needs restructuring.
Entity vesting is welcome on these files — investors can close in an LLC or similar structure without layering multiple entities — which matters for high-net-worth buyers who hold real estate for liability and estate reasons as much as cash flow.
Common Mistakes Investors Make
Assuming the signed lease always wins the DSCR calculation. It doesn’t — most programs use whichever figure is lower between the lease and the appraisal’s market-rent opinion.
Assuming a short-term rental qualifies at its full gross booking revenue. It doesn’t in this program — it qualifies at 80% of documented gross, and only after the investor clears the experience requirement.
Assuming 80% leverage is available on a large loan. It isn’t above $1,000,000 on this ladder — leverage steps down from there, and above $4,000,000 every figure is reviewed case by case, never a flat “up to.” Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
DSCR loans are business-purpose products, which means they’re reviewed differently than an owner-occupied mortgage and sit outside a different set of consumer disclosure timelines. Tax treatment on a rental property depends on how the funds are used and how title is held; investors should keep clear records and talk to a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Does a super jumbo DSCR loan require personal income documentation? No — qualification runs primarily on the property’s rental income covering the payment, not traditional personal-income documentation or W-2s, subject to lender guidelines. Credit, reserves, and property type still factor into the decision.
What credit score is needed for a loan above $3,000,000? Most lenders in the network set a 700 floor above that threshold, generally paired with a clean 48-month history and no more than one 30-day late in the trailing 24 months. Requirements vary by lender and file.
Can an investor get cash out on a $4,000,000 property? No — cash-out isn’t available above $3,000,000 on this ladder, and above that size only purchase and rate-and-term refinances are considered, on a case-by-case review basis.
Does a short-term rental qualify at its actual nightly income? Not directly — appraisers aren’t supposed to multiply a nightly rate by 30 to estimate monthly rent. Short-term-rental files in the network instead qualify on documented operating history or a formal short-term-rent analysis, discounted to 80% of gross, and only for experienced investors.
Is there a minimum DSCR to qualify at all? A ratio of 1.00 or higher typically earns full leverage. Ratios between 0.75 and 0.99 are a real path through select programs up to $2,000,000, with leverage and terms adjusted, subject to underwriting.
