Does An Existing Lease Set The Rent On A Jumbo DSCR Purchase — The Quick Read: No, not automatically. Across the wholesale DSCR network, underwriting typically uses the lower of the signed lease amount or the appraiser’s independent market-rent opinion — never the higher figure, and never the borrower’s own projection. On a jumbo file, this same rule applies; the only thing that changes at larger balances is that a second appraisal often confirms the number.
That’s the core mechanic. But the “why” and the exceptions matter more than the headline rule, especially once a purchase moves into jumbo territory where leverage steps down and every basis point of coverage counts.

The Lower-Of Rule, In Plain Terms
An appraiser’s market-rent opinion acts as a ceiling on rent that’s above market, and the lease acts as a ceiling on rent that’s below market. Whichever number is smaller is the one that drives the coverage ratio used for qualification. Investors don’t get to pick the flattering figure, and lenders don’t guess at it either.
This isn’t just an arbitrary lender preference. It comes from a documentation practice borrowed almost entirely from the conventional mortgage world. For a single-unit rental, the appraiser completes a comparable rent schedule. This is the same type of exhibit Fannie Mae calls Form 1007, which estimates monthly market rent for a one-unit investment property based on nearby comparable rentals. DSCR loans never sell to Fannie Mae or Freddie Mac. Still, most lenders in the non-QM space lean on this same form, or a close equivalent, because it’s the most standardized third-party rent opinion available.
For a 2-4 unit property, the appraiser usually starts with a broader operating income statement instead of a single rent schedule. That’s because a small multifamily building needs a per-unit breakdown first. Those numbers then roll up into one total for the property.
Here’s the practical effect of the lower-of rule:
- A tenant paying above market rent doesn’t help the deal. The extra rent the investor is collecting today simply doesn’t count toward the ratio.
- A tenant paying below market rent can hurt the deal, even when the investor’s business plan is to raise rent to market at the next lease turn.
- A vacant property has nothing to compare against, so the appraiser’s number is the only number that exists.
Why Lenders Don’t Just Use the Lease
Here’s the short answer: a lease is a private contract between two parties. It can be priced anywhere for any reason. Maybe it’s a favor to a relative. Maybe it’s a legacy tenant who’s been in place for a decade. Maybe it’s a short-term concession to fill a vacancy fast. Or maybe the rent was negotiated before a submarket appreciated. None of these situations show what the property would actually rent for on the open market today. That’s the number that matters for sizing a loan responsibly.
Appraisers are also explicitly barred from freelancing on this. Their job on a Form 1007 is to build a rent opinion from three or so comparable rental listings and adjust for differences between those comps and the subject property — not to assess the borrower’s income or vouch for a lease amount. According to appraisal-industry guidance, Blueprint’s explainer on Form 1007 walks through how appraisers analyze comparable rental data and adjust for property differences to arrive at a supported rent conclusion. The appraiser hands the lender a number. The lender — not the appraiser — decides how that number interacts with the lease.
Across the wholesale network files run through, this reconciliation step is one of the most common places a deal underwrites tighter than the investor expected. A buyer sees a signed lease at a strong number and assumes that’s the rent used for lender review. Then the appraisal comes back lower, and the coverage ratio drops with it — sometimes enough to change the leverage the file can actually support.
Does the Jumbo Size of the Loan Change the Rule?
No — the lease-versus-market-rent test applies the same way on a $400,000 purchase and a $4,000,000 purchase. What changes at larger balances is the appraisal process itself, not the underlying rule for which rent number gets used.
Most standard DSCR programs cap out around $3,000,000. Beyond that limit, a smaller number of lenders in the wholesale network can take qualified investors further — up to $10,000,000 on a portfolio-style investor program. Short-term-rental and no-ratio files stop at $2,000,000. Above $2,000,000, lenders typically order two independent appraisals instead of one. This isn’t because the lease-versus-market-rent test changes. It’s because both collateral risk and rent risk grow with loan size, and a second independent opinion lowers the chance that one appraiser’s comp set skews the number.
When two appraisals disagree on rent, the common practice across the network is to use whichever figure is more conservative. This matches the same lower-of approach used to compare a lease against an appraisal, no matter the loan size. The file gets sized on the number that’s least likely to be too optimistic.
Leverage steps down as loan size climbs, which makes an accurate rent number even more consequential on a jumbo file. On most files in the $150,000 to $1,000,000 range, purchase leverage tops out around 80% with a credit floor near 660. From $1,000,000 to $1,500,000, leverage typically tightens to around 75% with a higher credit floor near 700. From $1,500,000 up through $3,000,000, purchase leverage generally holds near 75% with credit expectations around 720. Above $3,000,000, leverage compresses further — commonly into the 60-65% range — and every file above roughly $4,000,000 gets reviewed case by case before submission, purchase or rate-and-term only, with no cash-out available at that size. A soft rent conclusion on a $5,000,000 purchase doesn’t just shave a little coverage — it can change which leverage tier the file even qualifies for. Investors weighing whether to move a purchase past that threshold may want to review qualifying for a jumbo DSCR loan before assuming a size and leverage combination will hold.
What Happens When the Lease Is Below Market?
This is the edge case that trips up more experienced buy-and-hold investors than the reverse scenario. A property with a long-tenured tenant paying well under market rent gets qualified on that lower, in-place number — not the appraiser’s higher market-rent opinion.
That can produce a coverage ratio that looks weak, or even sits under 1.00, on a property that’s actually a strong long-term hold. The investor’s real plan might be to re-tenant at market rent once the current lease expires in a few months. But qualification still runs on today’s documented number, not tomorrow’s projected one.
The good news: this doesn’t automatically kill a deal. Programs below 1.00 coverage are available through select lenders in Lendmire’s wholesale network, though leverage and terms adjust to compensate, subject to underwriting. For an investor with a short runway to a lease turnover — say, a tenant whose lease ends in a handful of months out of a 30-year loan term — accepting reduced leverage today in exchange for a below-market rent number can still make sense, especially if reserves and credit profile are strong elsewhere on the file.
Does This Apply the Same Way on a Purchase and a Refinance?
Mostly yes, but there’s one key difference. On a purchase, lenders can use the appraisal’s rent schedule alone or combine it with an existing lease. On a refinance, a documented operating history often carries more weight, since there’s a track record to point to. On a purchase specifically, the appraiser’s market-rent conclusion can stand on its own if the property is vacant. If a lease exists at closing, that lease gets compared against the appraisal.
Short-term rentals follow a completely different path on both purchases and refinances. On a refinance, twelve months of documented operating history typically drives the income figure. On a purchase, there’s no operating history yet. So the appraisal’s short-term-rental analysis fills that role instead. That figure is generally discounted to around 80% of gross projected income before it counts toward the ratio. Investors considering this route should look closely at how jumbo DSCR lenders decide between the lease and the market rent. STR income doesn’t get built the same way a standard lease-based rent schedule does.
One thing that doesn’t change: an appraiser can’t simply take a nightly rate, multiply by 30, and call that the monthly rent. The standard rent-schedule form isn’t designed for that math, which is one reason STR files typically run through a separate income-documentation path rather than the standard comparable-rent process.
Common Misconceptions Worth Clearing Up
“My signed lease is what the lender will use.” Not automatically. An above-market lease doesn’t raise the rent used for lender review past the appraiser’s market conclusion. Underwriting caps eligibility review at whichever number is lower, even when the lease is priced higher.
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.
“A below-market lease always tanks the deal.” Not necessarily. It pulls the rent used for lender review down, which can compress leverage or push a file toward a sub-1.00 structure, but that doesn’t make the property unfinanceable — it changes the terms available, subject to underwriting.
“The appraiser decides how much income I qualify for.” The appraiser produces the rent opinion. The lender decides how that opinion interacts with the lease and what number ultimately drives the ratio.
“Two appraisals on a jumbo file exist to catch a fraudulent lease.” The two-appraisal requirement above $2,000,000 is a loan-size and valuation-risk convention. The lease-versus-market-rent comparison itself applies identically at every balance, jumbo or not.
Key Terms Defined
DSCR (debt-service coverage ratio): a measure of whether a property’s rent covers its full monthly housing payment — coverage of 1.00 means the rent equals the payment, and higher numbers mean more cushion.
Comparable rent schedule: an appraisal exhibit, similar in function to Fannie Mae’s Form 1007, that estimates a property’s market rent by comparing it to similar nearby rentals.
Lower-of rule: the underwriting convention of using whichever figure is smaller — the signed lease or the appraiser’s market-rent opinion — to size the loan conservatively.
No-ratio loan: a select-program structure, available through a smaller number of lenders in the network to loan amounts around $2,000,000, that doesn’t rely on a published minimum coverage ratio; it typically requires strong credit, a clean housing history, and reduced leverage, subject to underwriting.
Business-purpose loan: a loan made for a non-owner-occupied rental property rather than a primary residence. DSCR loans are designed for non-owner-occupied investment properties, and because they’re business-purpose investor loans, they’re reviewed differently from a standard owner-occupied mortgage.
Frequently Asked Questions
Can I use my own projected rent instead of the appraiser’s number? No. Qualification runs on the property’s documented rental income — either the appraiser’s market-rent conclusion or an existing signed lease, whichever is lower — not on an investor’s own income projection or business plan.
What if the property is vacant at closing? The appraiser’s market-rent opinion is the only figure available, since there’s no lease to compare it against. That number drives the coverage ratio for the file.
Does a longer lease term help me qualify for more? Not directly. Lease length can matter for documentation and renewal risk, but it doesn’t change the lower-of comparison between the lease amount and the appraiser’s market-rent figure.
Why does a jumbo purchase sometimes need two appraisals? Above roughly $2,000,000, two independent appraisals are typically ordered to confirm both value and rent, since collateral and rent risk both scale with loan size. This is a size-based convention, not a change to the lease-versus-market-rent rule itself.
Can a below-market lease still work on a large purchase? Sometimes, subject to underwriting. Programs below 1.00 coverage exist through select lenders in the network, generally with reduced leverage. An investor with a lease rolling to market in the near term may find that trade-off reasonable, but it depends on the file’s credit profile, reserves, and overall leverage request.
Tax treatment can depend on how the funds 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.
