Super Jumbo DSCR Loans In Los Altos Hills — The Quick Read: Once a rental loan balance climbs past a few million dollars, leverage steps down in stages, credit floors rise, and reserve requirements stop scaling with the loan size. There’s no regulator-defined line for where “super jumbo” begins in DSCR lending — each lender in the space sets its own tiers. Los Altos Hills is a useful stress test for this math because its home values sit well above where standard DSCR programs stop working cleanly. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
That last point matters more than it sounds. Zillow’s tracking shows the average home value there running above $6 million, up roughly 5% over the past year, according to the Zillow Home Value Index. Redfin’s data puts the median sale price near $5.7 million, with price per square foot around $2,040, per Redfin’s local market tracking. At those price points, almost every deal lands past both the conforming loan limit and the point where a standard DSCR program tops out — which pushes financing straight into the super jumbo tier this article is about.

Key Takeaways
- “Super jumbo” is a lender convention, not a regulatory category — DSCR loans are non-QM and fall outside agency loan limits entirely.
- Leverage steps down as the loan balance climbs; reserves generally do not scale the same way.
- A property’s rent, not the borrower’s traditional personal-income documentation, drives the qualification decision.
- Credit floors, appraisal requirements, and cash-out availability all tighten at different thresholds — a file can clear one and still trip another.
- Coverage below 1.00, and no-ratio qualification, exist as real paths at reduced leverage through select programs — never as universal offers.
Key Terms Defined
DSCR (debt service coverage ratio) is the property’s monthly rental income divided by its full monthly housing payment — principal, interest, taxes, insurance, and any HOA dues, often shortened to PITIA. A ratio at or above 1.00 means the rent covers the payment in full.
Non-QM (non-qualified mortgage) describes a loan that isn’t underwritten to the repayment-capacity/Qualified Mortgage rule that governs most consumer mortgages. DSCR loans are a type of non-QM, business-purpose loan.
Business-purpose loan means the loan finances a property the borrower does not intend to occupy for more than 14 days a year — it’s an investment, not a residence.
Leverage is shorthand for loan-to-value, or LTV: how much of the purchase price or appraised value the loan covers versus how much the investor puts down in cash.
Reserves are liquid funds the borrower must have left over after closing, measured in months of the property’s payment, to cover a vacancy or rent shortfall.
Why “Super Jumbo” Has No Official Definition
There’s no agency line that marks where a jumbo DSCR loan becomes a super jumbo one — it’s a market convention, and every lender draws it differently. The reason traces back to how DSCR loans are classified in the first place.
A conventional jumbo mortgage is non-conforming for one reason only: it exceeds the county’s conforming loan limit, which the Federal Housing Finance Agency sets each year — $832,750 for most one-unit properties in the coming cycle, with a high-cost ceiling of $1,249,125 in the priciest counties. But that ceiling only governs agency-eligible, owner-occupant-style underwriting. DSCR loans never touch that framework. They’re non-QM from the start, priced and sized entirely at each lender’s discretion.
That’s the practical difference worth sitting with: a $4 million conventional jumbo loan and a $4 million DSCR loan are both “jumbo” in the loose sense, but only one of them was ever eligible for an agency loan limit to begin with. DSCR loans were built to sit outside that system, financing property purchased for business purposes rather than personal use.
Across the wholesale network Lendmire works with, the practical ceiling for a standard DSCR program tends to sit around $3,000,000. Above that, a smaller group of lenders continues financing — that’s the super jumbo tier, and it’s where leverage, credit, and reserve rules start moving independently of each other.
How the Leverage Ladder Actually Steps Down
Leverage on a DSCR loan doesn’t fall off a cliff at some arbitrary size — it steps down in stages, and purchase, rate-and-term, and cash-out transactions each have their own ceiling at every stage. Here’s the shape of it across the programs Lendmire places files with most often, subject to underwriting on every file:
| Loan Amount | Purchase LTV | Rate-Term LTV | Cash-Out LTV | 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+ |
A few patterns stand out here. Cash-out disappears entirely once a loan crosses roughly $3 million — above that line, every transaction Lendmire arranges is purchase or rate-and-term only. Second, above $4 million, every request is reviewed case by case before it’s even submitted; there’s no flat “up to” figure a lender publishes, because the file gets sized individually against the property, the borrower, and the program. Never assume 80% leverage on anything above $1 million — it doesn’t exist at that size in this space. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
For a property near Los Altos Hills price levels — say, in the $4 million to $6 million range that the local Zillow and Redfin figures suggest is typical there — an investor is working with 60% leverage on review, not the 75-80% range a smaller rental purchase would see. That’s the single biggest planning variable at this size, and it’s worth running before falling in love with a property. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Reserves: The Number That Doesn’t Move With Loan Size
Most investors assume reserves scale up proportionally as the loan gets bigger — they generally don’t. Across the programs Lendmire’s network uses, the reserve floor holds at six months of the property’s payment (PITIA, or ITIA if the loan is interest-only) whether the balance is $500,000 or $8,000,000. First-time investors — those without an established landlord history — typically face a 12-month reserve requirement instead, independent of loan size. There’s no extra reserve requirement stacked on for other properties an investor already has financed.
What actually tightens with size is leverage, the credit floor, and appraisal scrutiny — not the reserve count. That’s a genuinely counterintuitive point, and it’s one that trips up sophisticated buyers who assume a bigger loan automatically means locking up more cash in reserves. It usually doesn’t. The bigger constraint at high balances is the leverage ceiling itself.
Two appraisals are required above $2,000,000, specifically to guard against an inflated value or an overly optimistic rent estimate feeding into the coverage math. In markets with limited comparable luxury rentals — which is a fair description of much of the Bay Area’s hillside inventory — that second appraisal often becomes the pace-setting condition on the file.
Coverage Ratio: The Full-Leverage Path And The Alternatives
Rent gets documented on an appraisal form, not a spreadsheet — for a one-unit rental, that’s Fannie Mae’s Form 1007, the Single-Family Comparable Rent Schedule, which the appraiser completes to support a market rent figure, as described in Fannie Mae’s appraiser guidance. DSCR lenders lean on that same form to support rent even though the loan itself sits outside agency financing.
A coverage ratio of 1.00 or better — rent that at least equals the full monthly payment — earns full leverage on the ladder above. Below that, coverage from 0.75 to 0.99 is a real path through select programs in the network, capped at $2,000,000, with LTV and terms adjusted lower to compensate, subject to underwriting. No-ratio qualification also exists to $2,000,000, generally requiring a seven-year clean housing history and no late payments in the trailing 24 months, through select wholesale programs and subject to underwriting — there’s no published minimum ratio for this path, and none should be assumed.
Interest-only structuring is available on 30- and 40-year terms, up to a 120-month interest-only period. Leverage maxes at 75% for borrowers whose coverage clears 0.75 or better. Qualification is based on the interest-only payment (ITIA), not the fully amortized one. This lower payment structure is one lever that can pull a marginal-coverage property back into range — without touching the appraisal or the rent figure. Terms still vary by lender guidelines, property type, leverage, credit profile, and full file review.
Short-term rental income runs through its own lane rather than the standard long-term-lease comparable rent approach. It qualifies at 1.00 coverage or better, up to $2,000,000, using twelve months of documented operating history on a refinance or an appraisal-based short-term rent analysis on a purchase — counted at 80% of gross income, and reserved for investors with at least twelve months owning income property in the last three years. It’s not available on the no-ratio path. Whether a specific city or HOA even permits short-term rental operation is a separate matter entirely — that permission has to be documented at the property level, and it should never be assumed just because a market has strong nightly-rate potential. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Where The General Rule Breaks
A few edge cases are worth flagging before an investor assumes the ladder applies uniformly.
First, credit and coverage compound each other’s effect on the file — a marginal credit score paired with thin reserves can sink a deal that would clear easily on DSCR alone, even if each factor individually looks fine. Second, first-time investors face a genuinely different reserve bar (12 months versus 6) regardless of loan size, so a $1.5 million purchase from a first-time landlord can actually carry a heavier reserve burden than a $4 million purchase from a seasoned portfolio holder. Third, cash-out access shuts off entirely above roughly $3 million and is unavailable for 680-and-below credit above $1.5 million — an investor counting on pulling equity from a large-balance refinance should confirm that path exists before planning around it.
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.
Fourth, jumbo, non-QM, and DSCR are three different concepts. In casual conversation, people often flatten them into one phrase — but they’re not the same thing. Jumbo just means the loan exceeds the conforming loan limit. A conventional jumbo loan can still be underwritten to full Qualified Mortgage standards, with complete personal income documentation. Non-QM is the broader documentation category that DSCR sits inside, alongside bank-statement and asset-based programs. Some investors compare a bank-statement approach against DSCR for the same property. Lendmire covers this comparison in its bank statement loan coverage for Los Altos Hills. These investors are really choosing between two documentation paths inside the same non-QM umbrella — not choosing between jumbo and non-jumbo.
Fifth, being business-purpose doesn’t erase every consumer protection. DSCR loans sit outside the Ability-to-Repay/Qualified Mortgage rule, since the borrower isn’t occupying the property. This is confirmed by Pennymac’s compliance guidance on the business-purpose exemption. But prepayment-penalty restrictions under Regulation Z can still apply, depending on how the loan is structured. This detail is worth confirming on any given file — don’t just assume it away.
DSCR Isn’t A Fringe Product Anymore
You might wonder: if DSCR skips personal income documentation, does that mean weaker underwriting? It doesn’t. According to Scotsman Guide’s analysis of non-QM lending trends, the average non-QM borrower carried a 776 FICO score — virtually the same as conforming borrowers. Investor purpose loans made up roughly 28.5% of nonconforming originations recently. DSCR simply substitutes property analysis for income analysis. It doesn’t lower the bar. In fact, at the super jumbo tier, scrutiny gets tighter, not looser. Exact terms still depend on the lender’s guidelines, the property type, leverage, and a full review of the borrower’s file.
DSCR vs. Traditional Jumbo At This Price Point
| Factor | DSCR (Business-Purpose) | Traditional Jumbo (Owner-Occupied) |
|---|---|---|
| Review basis | Property’s rental income | Borrower’s income, DTI, traditional personal-income documentation |
| Documentation | No personal income docs required | Full income and asset documentation |
| Leverage above $4M | 60% on review, case by case | Varies by lender, often higher |
| Cash-out above $3M | Not available | May be available |
| Occupancy | Investment property only | Primary or second home |
| Regulatory framework | Exempt from ATR/QM | Subject to ATR/QM |
Some investors treat the property purely as a rental. This is often the case in Los Altos Hills, where rents typically trail purchase prices by a wide margin. For these investors, DSCR is often the more practical fit. That’s because it’s reviewed on rent, not on the borrower’s traditional personal-income documentation, even for a multi-million-dollar payment. But if a buyer intends to actually live in the home, traditional jumbo financing is the correct tool — not DSCR. DSCR is business-purpose lending only. It should never be treated as an owner-occupant alternative.
Are you comparing a similarly priced luxury rental in a different high-value micro-market? Lendmire covers this in its article on super jumbo DSCR loans in Beverly Hills. The same ladder logic applies there too. Only the property price and rent relationship changes — the mechanics stay the same.
The Practical Decision
Here’s the honest tension at this size: the higher the price, the more leverage compresses, and the more the file depends on documented rent rather than assumed rent. A $5 million property with rent that clears a strong coverage number at 60% leverage is a straightforward file. The same property with rent that lands the coverage ratio below 1.00 pushes the investor toward the reduced-leverage path, more cash down, or a stronger reserve position to offset the gap — all of which are real options, none of which are automatic. Running the numbers before shopping the property, not after, is what separates a deal that pencils from one that stalls in underwriting.
Because there’s no regulator-set line for where super jumbo begins, two lenders reviewing the identical property can land on different leverage, different reserve counts, and different appraisal conditions — neither one wrong, just different. That’s exactly why shopping a large-balance file across a wholesale network, rather than a single retail quote, tends to matter more at this size than at any other. Lendmire’s complete DSCR loans guide walks through the underlying qualification mechanics in more depth for investors building out the fundamentals first.
Tax treatment can depend on how loan proceeds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Is there a maximum loan amount for a DSCR loan? Yes — across the programs in Lendmire’s wholesale network, loan amounts run from $150,000 up to $10,000,000 on the portfolio investor tier, though the standard program tops out around $3,000,000. Short-term rental and no-ratio files are capped lower, at $2,000,000.
Does reserve requirement go up as the loan gets bigger? Not proportionally. The reserve floor commonly holds at six months of the property’s payment regardless of balance, stepping up to 12 months mainly for first-time investors rather than for larger loan amounts.
Can I do a cash-out refinance on a super jumbo DSCR loan? It depends on the balance. Cash-out is available with unlimited proceeds at or below 60% leverage, capped around $1,500,000 above that, and unavailable entirely above roughly $3,000,000.
Do I need a strong DSCR ratio to qualify above $3 million? Full 1.00 coverage earns the best leverage, but reduced-coverage and no-ratio paths exist through select lenders up to $2,000,000 — both require adjusted leverage and stronger credit, subject to underwriting.
Is short-term rental income counted the same way as long-term lease income? No. Short-term rental files route through a separate lane, using documented operating history or an appraisal-based nightly rent analysis at 80% of gross income, and they’re reserved for experienced investors with a recent landlord track record.
