Does A Tenant’s Lease Set The Rent On A Jumbo DSCR Purchase — The Quick Read: No, not by itself. The lender compares the tenant’s actual lease against the appraiser’s market-rent opinion and generally uses whichever number is lower. On a jumbo file, that comparison matters more, not less — a bigger loan means a wider gap between what the lease says and what the coverage ratio can actually support. A vacant property skips this comparison entirely and runs on the appraiser’s number alone.
That’s the short version. Now here’s how it actually plays out on a large loan, and where investors get tripped up.

Why The Lease Alone Doesn’t Set The Number
A signed lease tells the lender what a tenant is paying today. It does not tell the lender what the market will support tomorrow, and DSCR underwriting is built around the second question, not the first. So the lease is one input — not the input.
The appraiser produces an independent market-rent opinion using recent comparable leases in the area, typically pulled from properties that leased in the prior six to twelve months. That number lands on a form built for exactly this job — Fannie Mae’s Single Family Comparable Rent Schedule, known in the trade as the 1007 for single-family homes, or the 1025 for two-to-four unit properties. DSCR programs across the wholesale market borrowed this same rent-schedule mechanic from agency lending, even though DSCR loans themselves sit entirely outside the agency world.
Once that market-rent figure exists, most programs across the wholesale network compare it to the actual lease and use the lower of the two. That’s the rule that governs almost every occupied DSCR purchase.
The Lower-Of Rule, Plain And Simple
Here’s the mechanic in one sentence: if the property is leased, the lender runs the DSCR math on whichever is smaller — the rent the tenant is actually paying, or the appraiser’s market-rent estimate. Not the higher number. Not an average. The lower one.
This is a conservative-income rule, and it exists for a reason that has nothing to do with punishing good landlords. Lenders want the rent figure used for qualification to be defensible if the tenant leaves and gets replaced at market rate — or, just as often, if the tenant stays and keeps paying under market.
Once that rent figure is locked in, coverage — commonly called DSCR — is calculated by dividing the monthly rent by the full monthly housing payment, which includes principal, interest, taxes, insurance, and any HOA dues. A coverage ratio of 1.00 means rent and payment are roughly even. Above 1.00 means rent covers the payment with room to spare.
Across the wholesale network Lendmire places files through, a coverage ratio of 1.00 or higher typically earns full leverage on the size tier the loan falls into. That’s the baseline most programs are built around — not a guarantee, but the common target.
What Happens On A Vacant Purchase
If there’s no tenant in place, there’s no lease to compare against — so the appraiser’s market-rent opinion becomes the entire basis for the deal. This shows up constantly on jumbo purchases of new-construction or luxury properties that haven’t been rented yet.
That actually shifts the risk, not eliminates it. With no lease anchoring the number, the quality of the appraiser’s comparable-rent selection carries the whole file. A thin rental market with few comparable leases in the area can produce a more conservative number than an investor expects — which matters more on a jumbo purchase, where every tenth of a point on the coverage ratio can move the leverage tier the loan is reviewed for.
Above-Market And Below-Market Leases: Two Different Problems
An above-market lease does not raise your DSCR. If a seller advertises a property with a tenant paying well over what comparable units rent for, that premium generally gets capped at the appraiser’s market conclusion. The investor collects the higher rent every month — but the loan is sized as if they weren’t. This catches a lot of buyers off guard mid-contract, especially on jumbo deals where the seller’s pitch leans heavily on that above-market cash flow.
A below-market lease is the opposite problem, and it’s often worse. If a long-tenured tenant is paying well under market, the lower-of rule pulls the rent used for lender review down to that number — dragging the DSCR down with it, even though the appraiser’s opinion says the unit is worth more in rent. On a jumbo file this can be the difference between qualifying at the leverage an investor was counting on and getting bumped into a lower tier.
The practical fix, where it’s legally available, is timing: if a below-market lease can be legitimately reset to current terms before closing, that new lease is what the file gets underwritten against. A lease signed or backdated after closing has zero effect on a loan that’s already been sized off the old number — so this only works as a pre-closing lever, not an after-the-fact fix.
How This Changes At Jumbo And Super-Jumbo Size
The lease-versus-market comparison itself doesn’t change based on loan size. A $400,000 purchase and a $4 million purchase both run through the same lower-of logic. What changes is everything sitting downstream of that rent figure.
Leverage steps down as the loan balance climbs. Across the network, purchase and rate-and-term financing on the standard investor program run to 80% loan-to-value on balances up to $1 million, sliding to 75% between $1 million and $3 million, then down to 65% on the $3 million to $4 million band, and 60% on loans from $4 million up to $10 million — those upper tiers are reviewed case by case before submission, never a flat approval. Cash-out follows a steeper curve: generally 75% up to $1 million, tightening to 70% between $1 million and $1.5 million, and 60% from there up to $3 million, with no cash-out structure available above that point on most files.
Credit requirements tighten too. A 660 floor is typical up to $3 million; above that, files generally need 700-plus credit along with a clean payment history and seasoning on any past credit events. Loans above $2 million typically require two separate appraisals rather than one — which matters directly to this topic, because two independent rent opinions can occasionally disagree, and the lender still applies the lower-of logic against whichever lease exists.
Reserve requirements also scale differently than most investors expect. Six months of the property’s own payment in reserve is typical on most files, rising to twelve months for a first-time investor — but reserves generally don’t stack across other financed properties in the portfolio, which is a relief on files where an investor already owns fifteen or twenty rental units.
Coverage ratios below 1.00 are a real path on certain wholesale programs, generally capped around the $2 million mark, though leverage and terms adjust downward to compensate — this isn’t a workaround so much as a different pricing tier entirely, subject to underwriting. No-ratio qualification exists too, through select programs in the network, generally requiring a longer clean housing history and reaching similar size limits, always subject to underwriting and never available as a bare product with no envelope around it.
Short-Term Rentals Break This Model Entirely
Everything above assumes a standard, long-term lease. Short-term rentals — think a nightly-rate Airbnb or VRBO property — don’t fit the 1007/1025 framework at all, and lenders know it. McKissock’s appraiser education team has flagged that the standard rent-schedule form wasn’t built to capture nightly earning power, and Fannie Mae itself has clarified that appraisers can’t fold business income from short-term operations into the standard form.
For DSCR purposes, short-term rental purchases across the network are qualified using the appraisal’s own short-term-rent analysis rather than the 1007 — generally at a discount to projected gross rent — and typically require the investor to already have experience owning income property, not the appraiser’s long-term lease comp. On a refinance, twelve months of actual operating history usually replaces the appraisal projection. Either way, municipal permission to run a short-term rental has to be documented for that specific property; it’s never assumed just because a nearby property operates one. 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.

Key Terms Defined
DSCR (Debt Service Coverage Ratio): the monthly rent divided by the full monthly housing payment — a ratio above 1.00 means the rent covers the payment with room left over.
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.
PITIA: the full monthly housing obligation — principal, interest, taxes, insurance, and any HOA dues — used as the denominator in the DSCR calculation.
Form 1007 / Form 1025: the appraiser’s rent-schedule forms — 1007 for single-family properties, 1025 for two-to-four unit buildings — used to produce an independent market-rent opinion.
Lower-of rule: the underwriting convention of using whichever figure is smaller, the actual lease rent or the appraiser’s market-rent opinion, as the qualifying income.
Non-QM / business-purpose loan: a loan made for investment purposes rather than a primary residence, underwritten outside the standard agency (Fannie Mae/Freddie Mac) framework. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
What This Looks Like In Practice
Picture a jumbo purchase where the seller markets a tenant paying comfortably above the going rate in the area — the kind of listing pitched on strong rental returns. Run the appraisal, and the comparable leases nearby support a meaningfully lower figure. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and gets underwritten to that lower number — so the coverage ratio comes in tighter than the seller’s marketing suggested, sometimes clearing comfortably above 1.00, sometimes landing close enough to 1.00 that the leverage tier shifts.
Now flip it: a vacant, newly built property in the same price range with no lease at all. Here the appraiser’s number is the only input, and if the local rental comps are strong, the file can actually qualify more cleanly than the “occupied” example above — because there’s no below-market anchor pulling the number down.
The lesson isn’t that occupied is worse than vacant, or the reverse. It’s that the rent figure driving a jumbo DSCR file is never as simple as reading the number off a lease — and modeling the deal on the lease alone, without checking what the appraisal is likely to support, is the single most common way investors misjudge their own leverage before they’re even under contract.
Frequently Asked Questions
Does a higher-than-market lease increase my loan amount on a jumbo DSCR purchase?
No. Most programs cap the rent used for lender review at the appraiser’s market-rent conclusion, even when the signed lease is priced above it. The investor still collects the higher rent every month, but the loan itself is sized off the lower, appraisal-supported figure.
What happens if my tenant is paying well under market rent?
The lower-of rule generally pulls the rent used for lender review down to the lease amount, which can compress the coverage ratio below what a market-rent projection would suggest. Where legally permitted, resetting the lease to current market terms before closing — not after — is typically the only way to change that outcome.
Does the lease-versus-market comparison work differently on a $3 million purchase than a $400,000 one? The comparison itself works the same way regardless of size. What changes at higher balances is the leverage available, the credit floor, the reserve requirement, and whether one or two appraisals are required — all of which sit downstream of the rent figure, not inside the rent comparison itself. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Can I use projected short-term rental income instead of a lease on a jumbo purchase?
Yes, but it runs through a separate underwriting track rather than the standard lease-versus-appraisal comparison, because the standard rent-schedule form isn’t built to measure nightly-rate income. Short-term rental files typically qualify off the appraisal’s own short-term analysis or documented operating history, generally at a discount to projected gross rent, and require the property’s municipal short-term rental rules to be confirmed individually.
What if the property is vacant at closing — whose number do I use?
The appraiser’s market-rent opinion becomes the only input, since there’s no lease to compare it against. This shifts more weight onto the strength of the comparable rentals in the area, which can matter even more on a larger jumbo balance where a small swing in the coverage ratio moves the leverage tier.
