The Quick Read: A DSCR lender usually divides one qualifying monthly rent figure by the full monthly payment on the new loan. That rent figure is typically the lower of your signed lease and the appraiser’s market rent opinion. This is a common convention across the wholesale network, not a fixed rule, and programs differ. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.
- The appraiser estimates market rent. The lender decides how that estimate and your lease are used.
- A lease above market rent adds nothing to the ratio. A lease below market lowers it.
- Only the payment on the new loan counts. Your old payment is irrelevant on a refinance.
- Asking rent, listings, and unsigned rent increases do not count.
- Clearing the coverage floor is not the same as positive cash flow.
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. The biggest difference is the rent. On a refinance, you do not simply tell the lender what the property earns. Two documents get compared, and the weaker one usually wins.

Key Terms Defined
DSCR (debt service coverage ratio): The qualifying monthly rent divided by the monthly payment. A ratio of 1.00 means rent equals the payment.
PITIA: Principal, interest, taxes, insurance, and any association dues on the loan. It is the bottom half of the ratio.
Market rent: What the appraiser concludes the property would rent for, based on comparable rentals nearby.
Rent schedule: The appraisal exhibit that holds the market rent opinion. Single-family homes and one-unit condos use Form 1007. Two- to four-unit buildings use Form 1025, where the rent analysis is built into the report.
Rent roll: A list of each unit, its tenant, and its rent. It matters on multi-unit properties.
LTV (loan-to-value): The loan balance as a percentage of the appraised value.
Seasoning: The waiting period a lender wants after you buy a property before a cash-out refinance. About 6 months is the common expectation across the network.
What Is the Rent Number, and Who Produces It?
The rent number comes from two separate sources, and neither one is your opinion. The first is the lease you already have in place. The second is the appraiser’s independent market rent estimate. The lender then picks which figure goes into the ratio.
McKissock, an appraiser education provider, explains that Form 1007 estimates monthly rent from comparable one-unit rentals. The appraiser weighs location, condition, year built, property type, size, and any lease on the subject. The same page is plain about who decides how that figure is used: “ultimately, income falls under the lender’s scope.”
That sentence explains most of the confusion. The appraiser builds an opinion. The lender decides what it is worth.
The appraisal also does two jobs at once. The value opinion drives your LTV, and the rent opinion drives your coverage. A strong value does not rescue a weak rent opinion. The reverse is also true.
How the Lender Picks the Rent Figure, Step by Step
Across the programs Lendmire places files with, the sequence is consistent even when the details differ. Here is the usual order.
1. The appraisal is ordered. It produces a value and a rent schedule. Form 1007 covers single-family and one-unit condos. Form 1025 covers two to four units.
2. The appraiser builds market rent. The appraiser compares your property with a few similar rentals and adjusts for meaningful differences. The result is a monthly market rent as of a set date. The Fannie Mae rent schedule form shows the layout: three comparables, adjustments only for significant differences, and a final reconciliation of monthly rent.
3. You supply the lease evidence. That means the signed lease, any addenda, and proof the tenant pays. Deposits or bank statements usually serve as proof.
4. The lender selects the figure. The common convention is the lower of the lease rent and the appraiser’s market rent. If the property is vacant, market rent stands alone. If the lease is month-to-month or expired, many programs lean on market rent.
5. The lender builds the payment. PITIA on the new loan goes on the bottom of the ratio.
6. The ratio is computed. Rent used for lender review divided by PITIA.
7. The ratio feeds eligibility, leverage, and pricing. A stronger ratio opens better terms and leverage. A thinner one narrows both.
Why the lower figure? A lease can be inflated, stale, or unpaid. An appraisal can miss a unique property. Taking the lower of the two keeps one weak document from carrying the whole file. Simple as that.
Which Rent Counts in Each Situation?
The table below shows the typical treatment on a refinance. Programs vary, so read it as the usual pattern, not a promise.
| Situation | Figure usually used |
|---|---|
| Lease below market rent | The lease |
| Lease above market rent | Market rent |
| Lease equals market rent | Either; they match |
| Month-to-month tenant | Often market rent, per program |
| Fully vacant property | Market rent from the appraisal |
| Vacant unit in a multi-unit | Market rent for that unit |
| Lease to a relative | Lower of the two; extra review likely |
| Rent increase not yet signed | Not counted |
Two rows deserve a closer look. The first is the lease above market. Many investors assume a high lease helps. It does not. Rent above the appraiser’s opinion gets trimmed back to that opinion, so the extra buys you nothing.
The second is the unsigned increase. A raised rent counts only once it sits in a signed lease and the tenant is actually paying it. A rent increase after the appraisal date will not change the appraiser’s figure either.
The Math: What Goes on Each Side
The formula is short. Divide qualifying monthly rent by the monthly PITIA on the new loan. The numerator is rent, taxes and insurance live in the denominator, and association dues go there too.
Say you hold a duplex where the lease supports a ratio of about 1.05x and the appraiser’s market rent supports about 1.20x. The lender uses the lease, so the file runs at roughly 1.05x. Flip it, and a lease at 1.20x against a market opinion of 1.05x also lands at 1.05x. Same property, same payment, and the weaker document sets the number both times.
Working backward helps when you are trying to hit a target. The rent you need equals the new PITIA times your target ratio. Moving from 1.10x to 1.25x takes roughly a 14% rent increase, assuming the payment stays put.
Notice what the formula leaves out. Repairs, vacancy, management, utilities, and capital expenses are not in the calculation. Commercial textbooks define DSCR as net operating income over debt service, and they quote commercial benchmarks accordingly. Residential DSCR programs typically use gross rent over PITIA instead. Don’t mix the two.
Clearing 1.00x does not mean the property makes money after everything else. It means the rent covers the loan payment. If your ratio is thin, stress-test it at a lower rent before you commit.
Where does 1.00x fit? It is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Those are different paths, not one program with a moving floor.
How the Appraiser Builds Market Rent
The appraiser does not grade your lease. The appraiser builds an independent opinion from comparable rentals and then reconciles it into one monthly number. The Fannie Mae form also includes a comments area for vacancy and rent trends.
Only the form names carry over from the agency world. Agency underwriting rules do not govern DSCR loans. The lender’s own guidelines decide, and across the network those guidelines look quite different from an agency selling guide.
Two practical points follow. First, you cannot hand the appraiser a number. You can hand over a lease and a rent history, and those may inform the opinion. Second, your lease is not the appraiser’s job. It is the lender’s cross-check on the appraiser’s work.
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.
Proving the Lease Is Real
A lease is evidence, not proof. Lenders often want to see that the rent shown in the lease actually lands in your account. Deposit history or bank statements usually do that job.
This is where thin files get exposed. If the lease shows rent far above what the deposits show, the lender may fall back to market rent or to what is actually collected. A tenant who is behind on rent raises the same question. Underwriters tend to credit what is paid, not what is promised.
Keep the paperwork clean. Show base rent apart from any credits, free-rent periods, or one-time fees. Free rent and one-time fees are generally not recurring rent, so they do not belong in the monthly figure.
Where the Usual Rule Bends
The lower-of convention covers most single-unit rentals. These cases push it around.
Two- to four-unit buildings. All unit rents are summed against one building payment. Form 1025 carries the rent analysis. A single vacant unit gets its market rent, so one empty apartment does not zero out the building.
Short-term rentals. The standard rent form was built for 12-month leases. McKissock says the 1007 documents monthly rent, not nightly rent or business income, and that appraisers cannot multiply a nightly rate by 30. Class Valuation, an appraisal management firm, argues that forcing a short-term rental through the 1007 can produce an artificially low DSCR. HousingWire reports that experienced appraisers use a labeled narrative addendum built on occupancy, seasonal pricing, and comparable short-term rentals.
On the Lendmire side, short-term rental files carry their own parameters. Expect a 640+ credit score and about 12 months of hosting history. Coverage starts at 1.00 on refinances. Cash-out tops out around 75% LTV on standard rentals and 70% on short-term-rental collateral. 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. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Below-market and family leases. The lease side drops while the appraiser’s figure does not, so the lower-of rule picks the lease. Some programs review related-party tenants more closely. Some allow them at market with proof of payment, and others bar them. This is a lender-specific point.
Owner-occupied properties. Not DSCR-eligible. The loan is built for rentals.
Property types. Manufactured homes, single- and double-wide, log homes, and barndominiums are not offered in these programs. No rent figure changes that.
A future form change. HousingWire reports that the coming UAD 3.6 data standard will retire legacy forms including Form 1007. Narrative addenda should stay essential for short-term rental income. That is a future change, not today’s process.
What a Cash-Out Does to the Ratio
The old loan does not matter. Only the new PITIA does. That is the part many refinance borrowers miss.
Picture a rental that sits at a comfortable 1.30x on its current balance. You pull cash out, the balance grows, and the payment grows with it. The same rent now divided by a bigger payment might land near 1.05x. The rent did not move. The denominator did.
Cash-out on standard rentals tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. Leverage and coverage have to clear together. A bigger down payment or a smaller cash-out lowers the payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. Tax treatment varies; consult a qualified professional about how the funds are used. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Reserves depend on lender, leverage, loan size, and transaction type. About 6 months of PITIA is common, and loans above $1,500,000 typically step up to about 9 months. Conservative rate-and-term files at modest leverage can see reserves waived. Credit tiers run from a 620 floor in parts of the network to around 660 on most programs, and 700+ unlocks the strongest leverage.
If the Rent Number Comes In Low
Do not panic. Most fixes are mechanical, and they work in a specific order.
- Check which side is low. If the lease is the weak link, a new lease at market rent can fix it. It counts only once signed and paid.
- Lower the payment. A smaller cash-out, a larger equity cushion, or a longer term structure cuts PITIA. Extended terms such as 40-year and interest-only periods are available through select lenders in the network.
- Question the appraisal. If the rent comparables look off, ask whether stronger comparables exist. This helps only when the new evidence is real, such as nearby rentals with a similar bedroom count and condition.
- Look at the sub-1.00 path. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. It trades price for access.
- Wait and document. A tenant who pays a higher rent for a few months builds a record the next file can use.
The strongest files clear both tests: enough equity and enough rental coverage. Lendmire’s piece Can You Qualify for a DSCR Refinance on Monthly Rental Income? goes further on that balance.
Before You Apply
A short checklist saves a lot of back-and-forth.
- Gather the signed lease and any addenda for each unit.
- Pull 2-3 months of deposit records that match the lease rent.
- Separate base rent from credits and one-time fees.
- Decide whether a rent increase belongs in a signed lease before the appraisal.
- Estimate your new PITIA, not your old one.
- Test the ratio at a rent lower than your lease.
Each rental is tested alone on a standard DSCR loan. Other properties’ rents and payments are not pooled in.
Frequently Asked Questions
Does a higher lease help my DSCR?
No. Rent above the appraiser’s market opinion gets trimmed back to that opinion under the common lower-of convention. A lease below market works the other way and pulls the ratio down. If you are about to refinance, a lease signed near market rent is the cleanest outcome.
Which rent does the lender use on a vacant rental?
Market rent from the appraisal stands alone, since no lease exists to compare. On a multi-unit property, a vacant unit is typically counted at its market rent.
Does the old loan payment affect my ratio?
No. Only the payment on the new loan counts, including taxes, insurance, and any association dues. That is why a cash-out can pull a strong ratio down. The rent stays the same while the payment grows.
Can I use projected or asking rent?
No. Listings, asking rent, and your own projection do not count. A raised rent counts only after it is in a signed lease and the tenant is paying it.
Is clearing 1.00 the same as positive cash flow?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it, so a property can pass the lender’s test and still run thin in real life.
