The Quick Read: When a signed lease sits below market, the lease rent usually becomes the ceiling on the rent a lender counts. The appraiser’s market-rent opinion works as a second cap, mainly on leases that run above market. This is an underwriting convention, not a regulation, so the exact rent basis varies by program and by lender in the network.
- A below-market lease typically sets the numerator of the coverage ratio, even when the neighborhood supports more rent.
- An above-market lease rarely helps, because the appraiser’s figure usually caps it.
- Vacant, month-to-month, and expired situations often lean on market rent instead, depending on the program.
- A lower rent shrinks the supportable loan by more than its own percentage, because taxes and insurance do not shrink with it.
- Confirm the rent basis with the broker before the appraisal is ordered, not after.
Picture an investor who inherits a long-tenured tenant paying well under what the street now commands. The property looks strong on paper. Then the file reaches underwriting, and the coverage number comes back thinner than expected. This article explains why, and what an investor can do about it.

Key Terms Defined
DSCR (debt service coverage ratio): The property’s qualifying monthly rent divided by its monthly housing obligation.
PITIA: Principal, interest, taxes, insurance, and any association dues, which together make up the monthly obligation in the denominator.
Market rent: The appraiser’s opinion of what the unit would rent for today, built from comparable rentals.
In-place rent: What the current tenant actually pays under the signed lease.
Lower-of convention: The practice of counting the smaller of in-place rent and market rent when a lease exists.
What Does the Lender Actually Count?
The lender usually counts the lower of the signed lease and the appraiser’s market-rent figure. A below-market lease therefore sets the number. An at-market lease counts as is. An above-market lease is typically trimmed back to the appraisal.
| Lease vs. market | Rent typically counted | Effect on coverage |
|---|---|---|
| Below market | The lease rent | Ratio drops |
| At market | Either (they match) | Neutral |
| Above market | Market rent | No boost |
DSCR compares rent to PITIA only. It is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex all sit outside the calculation, so clearing 1.00 does not mean the property pays you.
Most programs we place files with start at coverage of 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. That path is a different product, not a lower floor on the same one.
How Underwriting Treats a Below-Market Lease, Step by Step
The process follows a fairly steady sequence.
1. The appraisal supplies market rent. For a one-unit property, the appraiser completes a comparable rent schedule. Fannie Mae’s Form 1007 is the standard format, and it adjusts rent concessions to the market rather than to the subject. DSCR loans are not agency products, but lenders borrow the form. The appraiser prepares it as an attachment, and the lender uses it to get a market-rent opinion, as the Freddie Mac version of the form describes.
2. The underwriter compares the lease to that figure. The appraiser is not grading your lease. The opinion is built independently from comparable rentals.
3. The smaller number becomes the numerator. For a below-market lease, that is the lease.
4. The result is divided by PITIA. That quotient is the coverage ratio.
5. The same rent also drives loan size. When rent is the binding limit, a shortfall cuts the supportable loan by more than the shortfall itself, since taxes and insurance stay fixed. A 10% rent gap can trim the loan by roughly 13% in a modeled case.
Documents usually include the executed lease, proof the tenant pays, and the appraisal’s rent schedule. Multi-unit files add a rent roll.
Why Do Lenders Lean on the Lower Number?
A lease reflects one tenant’s deal. Market rent reflects what the income would be if the tenant left and the unit were re-let. Underwriters want income that is both real and replaceable, so they take the more conservative of the two.
That is why an above-market lease earns no credit. The tenant could leave, and the next one would pay market. It is also why a below-market lease is not rescued by a strong neighborhood. The signed number is what the property actually earns today.
Programs differ here. Some lenders in the network use the appraisal figure whatever the lease says, which helps a below-market owner. Others look at the lease alone. Because the behavior is lender-specific, the rent basis is worth confirming before the appraisal is ordered.
Why Is the Lease Below Market? The Cause Changes the Fix
Diagnosing the gap matters, because each cause points to a different remedy.
| Cause | Typical treatment | Likely fix |
|---|---|---|
| Long-tenured legacy tenant | Lease rent counts | Renew at documented market rent |
| Discount to a relative | Extra scrutiny; market may govern | Document an arm’s-length lease |
| Recently signed cheap lease | Can lower counted rent | Avoid signing before appraisal |
| Stale pricing by the owner | Lease rent counts | Reset rent at renewal |
| Appraiser’s comps are wrong | Market figure too low | Request reconsideration with missed comps |
A family or non-arm’s-length tenant draws more attention. Market rent may govern, and a discounted lease may be given less weight. A lease-option or rent-credit arrangement counts only the market-rent portion.
Where the General Rule Breaks
The lower-of convention is a default, not a law. These situations commonly change the answer.
- No tenant in place. With no lease to compare, the appraiser’s market rent stands alone. That covers a vacant purchase as well as a vacant refinance.
- Month-to-month or expired lease. Market rent often carries the file, depending on the program.
- Multi-unit. Each unit is tested on its own. A below-market unit counts at its lease rent, and above-market units are capped at market. An above-market unit does not offset a below-market one. Small multifamily uses the Form 1025 income report for the appraisal.
- Short-term rentals. The 1007 is not designed for them. The form expects monthly-lease comparables, and nightly rates multiplied by 30 are not acceptable. Short-term-rental programs in the network use a different basis, with purchase leverage up to 75% LTV, about 12 months of hosting history, and a score of 640 or better, subject to lender guidelines.
- Tenant already in place. Whether the file is a purchase or a refinance, a signed lease with a tenant paying generally follows the lower-of treatment above.
How Do You Raise the Rent That Counts?
The levers are practical, and the order matters.
1. Decide which figure is actually the lower one. Renewing at market helps only if the lease, not the appraisal, was the binding number.
2. Renew at documented market rent before the appraisal. Give proper notice and keep the signed renewal.
3. Time the application after lease turnover. A fresh tenant at market makes the file simpler.
4. Ask whether the program allows market rent. Some do on certain lease statuses.
5. Consider a smaller loan. A lower balance shrinks PITIA, which lifts the ratio. A larger down payment helps the same way. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
When not to bother: if the lease expires soon and the property is not going to be financed until after turnover, a renewal push may not be worth the friction.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and 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.
What If the Appraisal Rent Comes In Low?
This is the opposite problem. The appraiser’s figure undercuts what the market supports, and it can cap even a healthy lease.
The usual fixes are to place a tenant at market or to request a reconsideration that names specific comparable rentals the appraiser missed. Listing screenshots rarely move the opinion. Bring signed leases on similar units nearby, with dates and terms.
What Does Not Count?
Projected rent on a leased unit does not replace the lease. Ancillary income such as parking, pet fees, or storage is generally excluded or treated cautiously, depending on the program. Gross rent against PITIA is the usual structure for these loans, not net operating income over debt service. Commercial explainers often use the second formula, which is a common source of confusion. Confirm which basis the program uses.
What Does the Investor Decision Look Like?
Run the file at three rent levels: the lease, the appraisal, and the lower of the two. If the lower-of number clears the program’s coverage floor with room to spare, a below-market lease is just a smaller profit. If it lands near or under 1.00, the choice becomes structural.
Across the network, most purchase files land at 75% to 80% LTV, and a cash-out refinance tops out around 75% LTV on a standard rental. Credit around 660 is common, 700 or better unlocks stronger tiers, and reserves commonly run about six months of PITIA, subject to lender guidelines. Loans range up to $3,000,000 on standard programs.
If coverage falls below 1.00, a sub-1.00 path is available through select lenders in the network, with leverage and terms adjusted. The better question is whether to use it. If the below-market lease is temporary and a renewal at market is coming, a lower-leverage structure can be a defensible bridge. If the property only works on paper at a rent the market will not pay, revisit the property, not the loan type.
For deeper background, the complete DSCR loans guide covers the rest of the program mechanics.
Common Mistakes
- Modeling coverage off the market rent when the lease will actually be used.
- Treating a family favor as market rent.
- Assuming a high lease boosts the ratio.
- Signing a cheap lease just before the appraisal.
- Ordering the appraisal before confirming the rent basis.
- Reading a clean ratio as proof of positive cash flow.
Frequently Asked Questions
Can I use market rent instead of my lease?
Sometimes. On vacant, month-to-month, or expired situations, market rent often carries the file. On a leased property, many programs cap rent at the lease. Some lenders in the network use the appraisal figure regardless, so confirm the basis first.
Does an above-market lease help my coverage ratio?
Usually not. The appraiser’s market-rent figure typically caps it, since a lender wants income that survives a change of tenant. Treat the excess as a bonus for your own cash flow, not for qualification.
Does a below-market lease block the loan?
Not by itself. It lowers the ratio and the supportable loan size, which can mean a smaller loan or a tier change. Select lenders in the network offer sub-1.00 paths with leverage and terms adjusted, subject to guidelines and credit review.
Is the lower-of rule a regulation?
No. No government rule sets it.
How does one cheap unit affect a multi-unit building?
Each unit is tested separately. The cheap unit counts at its lease rent, and an above-market neighbor does not offset it, so the blended ratio falls.
If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals. Tax treatment varies; consult a qualified professional.
A below-market lease is a pricing problem you can often solve with timing, so decide the rent story first and order the appraisal second.
