The Quick Read: Most programs we place files with count the lower of two numbers: the rent on the signed lease or the appraiser’s market-rent opinion. A tenant paying below market therefore caps the rent the lender counts, and the coverage ratio shrinks with it.
- The lease side moves when a tenant pays less. The appraiser’s market-rent opinion does not.
- An above-market lease is generally capped at market. It does not lift the file.
- A below-market lease can drop a property under 1.00 even when market rent would clear it.
- Renewing at documented market rent before the appraisal is the cleanest fix.
- Clearing 1.00 is not the same as positive cash flow.
Why Does the Lender Look at Two Rents?
A lender looks at two rents because a lease shows what the tenant pays today, while the appraisal shows what the property should earn. The conservative reading of the pair is the lower one. That keeps one friendly lease, or one stale lease, from deciding the loan.

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. No regulator dictates how rent is counted. Each lender or program writes its own rent treatment, which is why you will see variation across a wholesale network.

Key Terms Defined
DSCR (debt service coverage ratio): A ratio that compares the rent a property earns to what the loan costs each month. Investor-education sources such as Stessa describe it as income divided by debt service, and note that lenders use it to size loans.
PITIA: Principal, interest, taxes, insurance, and any association dues. On residential DSCR files, this is the monthly obligation the rent is measured against.
Lease rent: The monthly rent written in the signed lease between you and your tenant.
Market rent: The appraiser’s opinion of what the property would rent for today, based on comparable rentals.
Lower-of rule: The common convention of counting whichever is smaller, lease rent or market rent.
Rent schedule forms: Appraisal forms that carry the market-rent opinion. Form 1007 covers a one-unit property. Form 1025 covers two to four units.
Concession: A discount given to a tenant, such as a free month. It lowers the rent the tenant actually pays.
How the Lender Compares the Two Numbers
The lender compares them in five steps, and only the lease side changes when a tenant gets a discount.
1. The appraiser sets market rent. On a single-family rental, the appraiser uses Form 1007. As Blueprint explains, the form estimates monthly market rent by comparing the property to similar rentals, with adjustments for size, condition, and location. On two to four units, per-unit rents come from the Form 1025 report.
2. You supply the lease. Expect a signed lease, proof the tenant actually pays (deposits or bank records), and a rent roll on multi-unit properties.
3. The lender picks the lower figure. Your tenant’s discount does not push the appraiser’s number down. So the lower-of test lands on the lease.
4. The lender divides that rent by the full monthly obligation. That is PITIA, not just principal and interest.
5. The result is your coverage ratio. It is then weighed against the program’s floor, your credit, leverage, and reserves.
Across our wholesale network, 1.00 is where select programs start. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
What a Below-Market Lease Does to the Ratio
A discount hits the ratio in direct proportion, because taxes, insurance, and dues do not shrink when the rent does.
Run the numbers on a modeled example, not market data. Picture a rental whose market rent supports coverage of about 1.20x. The tenant has been there for years and pays roughly a quarter less than market. The lease side supports coverage near 0.90x. Same house, same loan, same obligation. The only thing that changed is which rent the lender counted.
That swing matters in two ways:
- Under the floor. The file may fall below the 1.00 start point many select programs use. A sub-1.00 path exists through select lenders, with leverage and terms adjusted.
- Smaller loan. If the file clears but thinly, the lender may size the loan lower or hold leverage down. Lenders use this ratio to size the maximum loan, which is why a few points of rent shortfall can move proceeds on a cash-out refinance.
Now flip it. An above-market lease is generally capped at market, so it does not rescue a thin file. And a rent bump scheduled for next year usually earns no credit today.
Which Rent Counts in Each Situation
Treatment is program-specific, so read this as the usual pattern, not a promise.
| Situation | Rent the file leans on | Risk |
|---|---|---|
| Below-market fixed-term lease | The lease | Ratio capped low |
| Lease at market | Either (they match) | Low |
| Above-market lease | Market rent | No upside credit |
| Month-to-month or expired | Often market rent or appraisal | Weaker file |
| Vacant or new purchase | Appraiser’s market rent | Appraisal-dependent |
| Family or related-party tenant | Closer review, lease if discounted | May be excluded |
| Subsidized unit | Program-specific | Varies |
| 2-4 units | Per-unit test | Mixed leases |
Month-to-month, expired, and short-remaining-term leases are generally weaker files, not blocked ones. The underwriter may lean on the appraisal instead. If your tenant is family, our piece How a DSCR Lender Tests a Family Lease Against Market Rent covers that case in depth.
Purchase Versus Refinance
On a purchase of a vacant property, there is no lease to compare. The appraiser’s market rent is the only number. That is the simplest case.
On a purchase with a tenant in place, programs differ. Some stay with the lower-of convention. A few lenders in the network lean on actual rent, or allow a variance when a current lease exists. Which behavior applies depends on the program, so ask before you contract, not after the appraisal lands.
On a refinance, the tenant has often been in place for years, which is exactly how legacy leases cause trouble. A long-tenured tenant at an old rent is a common way a lease hurts a cash-out refinance, where leverage tops out around 75% LTV across most of the network and about 6 months of seasoning is the usual expectation. A thin ratio plus a leverage cap leaves little room.
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.
Two-to-Four Unit Buildings With Mixed Leases
On a duplex, triplex, or fourplex, rents are generally tested unit by unit using the Form 1025 report. Some units may sit below market while others sit above.
Picture a fourplex with three units at market and one long-term tenant well under it. The three market units count at market. The discounted unit counts at its lease. An above-market unit is capped at market, so it does not offset the cheap one. Some pooled or blanket structures test combined rent against combined obligation instead, which can soften this. That is a program feature, not a given.
Concessions, Discounts, and Related-Party Leases
A free month or a reduced deposit lowers the effective rent on the lease side. It does not touch the appraiser’s number, so the lease again becomes the lower figure.
Family or affiliate tenants get closer attention. Some programs review these leases harder, and some exclude them. A discounted family lease lowers the counted rent. If you occupy the property yourself, it is not a DSCR loan at all.
Short-term rentals work differently. Form 1007 is a monthly-rent form. It does not estimate nightly rates, so platform history or a market-data report usually carries these files. AirDNA notes that lenders scrutinize short-term-rental DSCR files more closely because income varies. On our network, short-term-rental purchases run to 75% LTV, with a 640+ score and about 12 months of hosting history expected. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
Documents That Prove the Lease
A lease is only worth the proof behind it. Gather these before you apply:
- A signed, current lease with the term and rent clearly stated.
- Bank records or deposits showing the tenant pays that amount.
- A rent roll for multi-unit properties.
- Any amendments, renewal addenda, or concession terms.
A lease with no payment evidence carries little weight. Deposits that do not match the lease invite conditions.
Fixes, and What Not to Do
The fixes are practical and mostly about timing.
- Renew at documented market rent. Get an executed amendment and show the payment history. Check notice periods and local rent rules, and weigh the risk of losing a good tenant.
- Wait for turnover. Re-lease at market, then refinance.
- Do not sign a cheap lease right before applying. It hands the lender a lower number on purpose.
- Hand the appraiser good information. Provide the lease terms and any upgrades so the comps reflect the property.
- Model both rents. Stress the lower one before you commit.
A larger down payment can lift coverage by shrinking the obligation. But it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
When the Ratio Comes In Thin
This is a decision, not a dead end. Your options usually run in this order: renew at market, wait for turnover, lower the loan amount, or move to a different structure. Select lenders in the network offer interest-only periods and extended terms, which can change the obligation the rent is measured against. Sub-1.00 coverage is also available through select lenders, with leverage and terms adjusted.
Files stall less on the ratio than on surprises. Investors who model the lease number early, before the appraisal, rarely get a shock. Those who model market rent only often do.
Also remember what the ratio is not. DSCR compares rent to PITIA only. Clearing 1.00 is not positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Your qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.

Frequently Asked Questions
Can I use market rent instead of my below-market lease?
Sometimes, but not by default. Many programs count the lower of the two, so the lease usually controls. A few lenders allow a variance when a current lease exists. Ask each lender how it treats actual rent before you apply.
Does an above-market lease help me qualify?
Generally no. Above-market leases are typically capped at market rent, so you get no credit for the extra. The file is tested on the lower, supportable figure.
What if my tenant is month-to-month?
A month-to-month tenancy is generally a weaker file, not a blocked one. The underwriter may lean on the appraiser’s market rent or ask for more payment history. Treatment is program-specific.
Do concessions like a free month count?
They lower the rent the tenant effectively pays, so they weigh on the lease side. The appraiser’s market-rent opinion does not drop, so the lower-of test lands on the discounted lease.
Why did my loan shrink after the appraisal?
Lenders size loans from the coverage ratio. If the counted rent came in lower than you modeled, the ratio dropped, and proceeds or leverage can drop with it. Taxes, insurance, and dues do not fall when rent does.
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. Programs change, every file is underwritten individually, and nothing here is a commitment to lend. Tax treatment varies, so consult a qualified professional.
