The Quick Read: On a rented property, most DSCR lenders use the smaller of two numbers as the rent: the signed lease or the appraiser’s market-rent opinion. Rent above market adds nothing to coverage, and rent below market pulls it down. A vacant property is tested on the appraiser’s number alone.
- The lower figure becomes the top of the coverage ratio, and the monthly payment sits underneath it.
- An above-market lease puts real cash in your pocket but does not raise the qualifying ratio.
- A below-market lease drags the ratio down, and the discount follows the file.
- This is a lender convention, not a law, so treatment varies by program and situation.
- Passing the test does not mean the property cash-flows once repairs, vacancy and management are counted.
Key Terms Defined
DSCR (debt service coverage ratio): The property’s rent used for lender review divided by its monthly housing payment. A ratio of 1.00 means rent equals the payment.
PITIA: Principal, interest, taxes, insurance, and any association dues. It is the full monthly obligation the rent has to cover.
Market rent: What an appraiser believes the unit would rent for today on a typical 12-month lease, based on comparable rentals nearby.
Form 1007: The appraiser’s rent schedule for a one-unit property. Form 1025 does the same job for two- to four-unit properties.
Lesser-of rule: The convention that, where a lease exists, the lower of lease rent and market rent is the rent that counts.

What the Rule Actually Says
The rule has one job: it keeps the rent number from being inflated. A lender is lending against the property’s income, so it wants a figure a future owner could reasonably expect to collect. If a lease is above market, a new tenant might not pay that much. If a lease is below market, the owner is currently collecting less than the property could earn, and the lender counts what you are actually earning.
It helps to know what the rule is not. No federal regulator owns it. DSCR loans are business-purpose investor loans, and each lender or investor sets its own treatment. The lease-or-market comparison is the common convention across the wholesale network Lendmire works with, and Lendmire’s role is that of a broker arranging financing through select lenders. Details still shift by program, by transaction type, and by whether anyone lives in the unit.
Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. That is why this single comparison matters so much to your file.
How Underwriting Applies It, Step by Step
The mechanics are simple once you see them in order.
1. The appraisal is ordered with a rent schedule. A one-unit property gets Form 1007. A two- to four-unit property gets Form 1025.
2. The appraiser builds the market-rent opinion. This means pulling comparable rentals and adjusting for meaningful differences between each comp and your property.
3. The lender collects the lease and proof of payment. For a fixed-term lease, that is the signed lease plus evidence the rent is being paid, such as bank deposits. A multi-unit property adds a rent roll.
4. Underwriting compares the two figures. The lower one becomes the rent in the ratio.
5. The ratio is calculated. The rent is divided by the full PITIA. On a cash-out refinance, the test runs on the new, larger payment, not the old one.
6. Pricing and leverage respond to the result. Stronger coverage generally opens better terms and leverage tiers.
That last step is where the money is. Across the network, 1.00 is where many select programs start. A separate path through select lenders takes coverage below 1.00, with leverage and terms adjusted. Neither one is a guarantee, and the exact cutoffs depend on the lender, the credit profile and the property.
Worked Examples
These are modeled assumptions, not market data. Every number is a ratio, because the ratio is what the lender actually reads.
Above-market lease. Say the signed lease would produce 1.25x coverage. The appraiser’s market rent produces 1.10x against the same payment. The lender uses 1.10x. The extra rent is real income to you, but it does not count toward qualifying. A borrower who planned the loan around 1.25x finds the cushion gone.
Below-market lease. Say the lease produces 0.95x coverage, and market rent would produce 1.15x. The lender uses 0.95x. The property looks like a fit on paper at market rent, but the legacy lease follows the file into the ratio. At 0.95x, the file falls below the 1.00 start point of many select programs. A sub-1.00 path exists through select lenders in the network, with leverage and terms adjusted, and it is reviewed under lender guidelines and credit approval.
Duplex, unit by unit. Say one unit is leased above market and the other below. Many programs test each unit on its own, so the surplus on one unit does not cancel the shortfall on the other. Ask your lender how it treats this before you count on the blended number.
Which Rent Counts? A Quick Reference
| Situation | Rent typically used |
|---|---|
| Fixed-term lease in place | Lower of lease or market rent |
| Month-to-month or expired lease | Usually market rent, lease as support |
| Newly signed lease | Lower of the two, or lease if appraisal supports it |
| Vacant or between tenants | Appraiser’s market rent alone |
| Related-party tenant | Market rent, with closer review |
| Former primary home | Market rent plus conversion proof |
Treat the table as typical treatment, not a promise. The pattern is consistent: the more independent proof there is behind the rent, the more weight it gets.
How the Appraiser Builds Market Rent
The appraiser’s number is an opinion based on comps, and that explains why it often differs from what you modeled. The form itself is an appraiser attachment that estimates market rent, and its instructions say adjustments should reflect only significant differences. Rent concessions are adjusted to the market, not to your property.
The comps are typically a handful of recent rentals near your property. They can lag current asking rents, because they reflect signed leases, not listings. If your own modeling used asking rents from a listing site, expect the appraisal to land lower.
Do not expect the appraiser to adopt your lease as the answer. The form also calls for lease terms on the subject property, so the lease is documented, but it is evidence, not a ceiling or a floor on the opinion. Lendmire’s piece Lease Rent vs 1007 Market Rent: Which Figure a DSCR Lender Uses goes deeper on how the two numbers meet in the file.
Where the General Rule Bends
Vacant property. With no lease to compare against, the appraiser’s rent schedule is the only number. On multi-unit properties, treatment of vacant units varies by program. Some count the appraiser’s rent for them and some are stricter, so ask which applies before you rely on an assumption.
Month-to-month and expired leases. These are usually tested on market rent. The lease or payment history supports the file but does not set the number.
Rent-stabilized units. The legally registered rent may govern instead of market rent. This is program-dependent.
Condos with leasing limits. A condo with HOA restrictions on renting may be ineligible regardless of rent coverage.
Portfolios. Each property is evaluated individually, then blended into one ratio.
Short-term rentals. The 1007 is built around monthly rent, not nightly rates or business income. McKissock’s appraisal education makes the same point and adds that the lender makes the final income determination. Fannie Mae’s own appraiser update says its guide is silent on whether short-term rental income counts at all. Multiplying a nightly rate by 30 is not a valid market rent. Short-term rental files use their own underwriting, with a typical 640+ credit score and about 12 months of hosting history, and cash-out ceilings of 70% on short-term-rental collateral versus 75% on standard rentals. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Different formulas. Some lenders use variations, such as capping in-place rent at a percentage of market. That is why asking beats assuming.
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.
When the Rule Works Against You
If the number is low, you have options, and each one has a tradeoff. Here they are from lightest to heaviest.
1. Fix a factual error. If the appraiser used a mismatched comp or misread the unit, supply recent signed local rentals the appraiser did not use. Asking prices and opinions do not move the number.
2. Renew the lease at documented market rent. This repairs the lease side if the tenant agrees, but it costs you a rent conversation and a new term.
3. Borrow less. A larger down payment lowers the monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
4. Choose a different property. If the submarket’s market rent will not carry the payment, no lease strategy changes that.
5. Look at a sub-1.00 path. This route is available through select lenders in the network, with leverage and terms adjusted. It is reviewed under lender guidelines.
On a below-market-lease deal that also runs large, Lendmire’s guide on how to qualify for a jumbo DSCR loan when the lease is below market rent covers that scenario in detail.
Practitioner pattern: borrowers get surprised when they underwrite off the asking rent or the best lease on the property, and the appraisal comes back lower. Run your numbers on the conservative figure before you go under contract. Check actual comparable leases, then leave a cushion.
What Program Limits Still Apply
The rent test is only one gate. Typical purchase leverage across the network runs 75%–80% LTV on an investment-property purchase, and cash-out refinances top out around 75% LTV. Reserves are commonly around 6 months of PITIA, stepping up to about 9 months above $1,500,000, though they vary with leverage, loan size and transaction type. Standard programs run up to $3,000,000. Manufactured homes, log homes and barndominiums are not offered in these DSCR programs. Every figure is a typical range subject to lender guidelines, and every file is underwritten individually. For the full picture, see the complete DSCR loans guide.
Passing the Test Is Not Positive Cash Flow
DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. A ratio over 1.00 means the rent covers the housing payment on paper. It does not mean the property puts money in your pocket each month. Treat the ratio as a gate to clear, then run a real operating budget.
Before You Apply: Questions for Your Lender
- How do you treat a vacant unit in a multi-unit property?
- Do you test each unit separately or blend them?
- What proof of rent payment do you want for a fixed-term lease?
- How do you handle a lease signed shortly before the application?
Frequently Asked Questions
Does an above-market lease help my DSCR?
No. The appraiser’s market rent becomes the ceiling, so the extra rent adds nothing to the qualifying ratio. You still collect it, and it still helps your actual returns.
What happens if my lease is below market?
The lease usually becomes the rent in the ratio, which lowers coverage. Renewing at documented market rent, borrowing less, or choosing a different property can improve the file, depending on lender guidelines.
What rent is used on a vacant property?
The appraiser’s market rent alone, since there is no lease to compare.
Is the lesser-of rule the same at every lender?
No. It is a convention, not a regulation, so details differ by program and transaction. Some lenders add their own caps or formulas.
Can I dispute the appraiser’s rent number?
Yes, through the lender, by supplying recent signed local rentals the appraiser did not use. Factual errors in comps are the strongest basis.
