The Quick Read: Most programs count the lower of two numbers: the signed lease rent and the appraiser’s market-rent opinion. A long-held tenant paying below market therefore usually caps the rent at the lease figure, and the coverage ratio drops with it. Years of good tenancy do not earn extra credit.
- Rent above market earns no bonus. Rent below market usually becomes the ceiling.
- A month-to-month or expired tenancy often shifts treatment toward market rent, depending on the program.
- Future rent increases do not count until they are signed and in place.
- Clearing 1.00 coverage is not the same as positive cash flow.
- Treatment varies by lender, so the file should be matched to the program before you apply.
You may be asking one of two questions, so it helps to separate them. One is about a tenant who is mid-lease and paying an old, low rent. The other is about a furnished mid-term rental, meaning stays of roughly a month or longer. This article is built mainly around the first. The second gets its own section below.

Key Terms Defined
DSCR (debt service coverage ratio): The property’s qualifying monthly rent divided by its monthly obligation. A result of 1.00 means rent equals the obligation.
PITIA: Principal, interest, taxes, insurance, and any HOA dues. It is the monthly obligation in the denominator.
In-place rent: The rent your tenant actually pays under the current lease or tenancy.
Market rent: What the appraiser concludes the unit would rent for today, based on comparable rentals.
Legacy lease: An old lease, or a long tenancy, whose rent never kept up with the market.
Month-to-month tenancy: A tenancy with no fixed end date. Either side can end it with proper notice.
Holdover: A tenant who stays after the written lease term ends.
Seasoning: The waiting period a lender wants between buying a property and refinancing it.
Which Rent Does the Lender Count?
The lender counts the lower of the lease rent and the appraiser’s market rent. That convention is common across the wholesale network Lendmire places files with. A few lenders in that network lean on actual rent instead, so it is a strong tendency, not a universal law.
Here is why the convention exists. A lender does not want to credit income that may not survive a vacancy or a renegotiation. A commercial real estate advisory firm describes the same logic when lenders normalize contract rent to market. If normalizing lowers income, the coverage ratio falls and the supportable loan can shrink.
Applied to your tenant, the outcomes look like this:
| Situation | Typically counted | Effect on ratio |
|---|---|---|
| Lease below market | Lease rent | Ratio falls |
| Lease at market | Either figure | Little change |
| Lease above market | Market rent | No extra credit |
| Month-to-month or expired | Often market rent | Program-dependent |
| Vacant | Market rent | Program-dependent |
| 2–4 units | Tested unit by unit | Gap shows per unit |
No law sets this rule. DSCR loans are business-purpose investor loans, reviewed differently from a standard owner-occupied mortgage. Which rent counts is a program convention, and it differs between programs.
How Underwriting Treats the Rent, Step by Step
The process runs in a set order, and your rent number gets decided in the middle of it, not at the start.
Step 1: The appraisal. The value appraisal comes with a rent schedule. On a single-family home or condo, the appraiser uses Form 1007, the Single-Family Comparable Rent Schedule. On two to four units, the appraiser reports on Form 1025, which gives a market-rent opinion for each unit. The appraiser sets that opinion, not you and not your broker.
Step 2: The lease file. The lender wants the signed lease. For small multifamily it also wants a rent roll. Proof of payment, such as bank deposits that match the lease, is typical. Requirements differ by program.
Step 3: The comparison. The lender puts the lease rent next to the appraiser’s number. Lease below market means the lease usually wins as the figure. Lease above market means market usually wins. If the two are close, nothing much changes.
Step 4: The ratio. Rent used for lender review goes over PITIA. On a cash-out refinance, coverage is tested against the new, larger obligation, not the old one.
Step 5: Tenancy status. A fixed-term lease is treated differently from a month-to-month or expired one. With no term to rely on, many programs lean toward market rent. That can help a below-market tenant’s file, but the program decides.
Step 6: Unit-by-unit checks. On a duplex, triplex or fourplex, each unit carries its own lease and its own market figure. One legacy tenant drags only their own line, though it still pulls the total down.
A detail worth knowing: the 1007 instructions say rent concessions are adjusted to the market, not to the subject property. So your discounted legacy lease should not drag the appraiser’s market conclusion down. It drags only the lender’s lower-of figure. Two different numbers, two different jobs.
These are appraisal form names borrowed from the agency world. DSCR loans are non-QM, and agency rules do not govern them. The forms are simply the common format for the rent opinion.
Mid-Lease or Mid-Term Rental? The Two Meanings
A furnished mid-term rental is a different animal from a mid-lease tenant. Both get searched under the same words, so here is the difference.
Mid-lease tenant. Your tenant signed a long-term lease, or has rolled month to month for years, and pays less than today’s market. Everything above applies directly.
Furnished mid-term rental. The unit hosts stays of a month or more, often to traveling professionals. Lenders have no single method for these. Programs tend to treat a signed monthly lease like any other lease, and to treat shorter, platform-based stays under short-term rental rules.
The short-term rental route has its own parameters. Across the network, purchase leverage on short-term rentals tops out at 75% LTV. Cash-out on short-term rental collateral tops out at 70%. Expect a 640+ credit score and about 12 months of hosting history. Coverage floors are 1.00 on both purchases and refinances. Multiplying a nightly rate by 30 is not a supported shortcut. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
If you are converting a long-held tenant’s unit to furnished stays, you are changing the income type. That change comes with its own history requirement. Short-term rental rules can vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
Where the General Rule Bends
The lower-of rule has edges. These are the places where files stop following the pattern.
Month-to-month long-term tenant. This is the most common bend. With no lease term to protect, many programs lean on market rent, with payment history as support. Some programs still use the lease figure. Ask before assuming.
Purchase versus refinance. Some programs treat a below-market tenant differently on a purchase than on a refinance. Others do not. Treatment varies by program, and a loan officer with many lender guidelines at hand can tell you which is which.
Lease expiring soon. Programs often treat the lease first and switch to market rent only after it ends. A renewal at documented market rent before the appraisal can fix the lease side of the comparison.
Tenant related to the borrower. Related-party tenancies tend to get closer review and often fall back to market rent. A lender wants evidence that the rent is a real, arm’s-length number.
Rent that does not match deposits. Cash payments, side agreements, or unrecorded amendments create a gap between the lease and the bank statements. Underwriters notice the gap. Clean it up before the file goes in.
An appraiser’s weak comps. If the market-rent opinion looks low or poorly supported, signed comparable rentals from nearby can help. This is a legitimate conversation to have with the appraisal process, not a way to inflate a number.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs, whatever the tenant’s rent looks like.
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.
Can You Raise the Rent Before You Apply?
Sometimes, and the lease decides. A fixed-term lease generally locks the rent for the term unless the lease itself allows a mid-term increase. A month-to-month tenant can usually receive an increase with proper written notice, though rent-controlled areas cap what you can charge. A legal-information site on unlawful rent increases lays out why those rules differ place to place.
For a tenant on a fixed term, the realistic paths are these:
- Wait for the term to end, then renew at documented market rent.
- Negotiate a written amendment the tenant agrees to.
- Leave the rent alone and accept a lower ratio on this file.
Your timing matters as much as your legal right. Underwriting does not credit a bump that has not happened. The sequence that works is to sign the new rent, collect proof the tenant is paying it, and only then order the appraisal. Raising rent the week before the application lands, with no payment history behind it, gives an underwriter little to rely on.
Lendmire’s piece How to Raise a Long-Held Tenant’s Rent Before a DSCR Refinance walks through that sequence in more detail.
A rent reset is a business decision, not just a financing one. Many long-term tenants drift below market because no renewal date ever prompts a conversation. A BiggerPockets article on below-market rent describes that drift and suggests an annual increase schedule as the preventive fix. Whether to move in one step or phase it in is a judgment call. A large jump can prompt turnover, and a vacancy hurts a file more than a modest ratio does.
This is a genuine toss-up for many owners. Resetting to market lifts the ratio and the supportable loan. Holding the rent keeps a reliable tenant and avoids turnover cost, but costs you leverage on this particular refinance. Neither choice is wrong.
| Option | Upside | Risk | Suits |
|---|---|---|---|
| Reset to market | Higher ratio | Tenant may leave | Thin files |
| Phase in increases | Keeps tenant | Slower fix | Stable tenants |
| Hold rent, smaller loan | No disruption | Less leverage | Strong equity |
| Wait, apply later | Cleaner file | Delays the plan | Flexible timing |
What the Gap Does to Your Loan
A below-market lease cuts the ratio even though the property’s earning power is unchanged. A lower ratio can reduce the loan amount the rent supports. It can also affect pricing and leverage tiers, subject to lender guidelines.
Run the numbers on a single-family rental. Say market rent supports coverage of about 1.20x. If the lease runs around 85% of market, the lender credits the lease and coverage lands near 1.02x. That clears 1.00, where many select programs start. A tenant at 80% of market lands near 0.96x. Coverage below 1.00 is a separate path. It is available through select lenders in the network, with leverage and terms adjusted. These ratios are modeled assumptions, not market data.
Now picture a fourplex with one legacy tenant. Three units rent at market. The fourth rents at about 70% of market. Total rent used for lender review is about 92.5% of full market rent. If full market rent would produce 1.20x, the file lands near 1.11x. One legacy unit costs less than a single-family gap would, because the other three units cushion it.
Leverage rules sit on top of the ratio. On an investment-property purchase, most files land at 75%–80% LTV, and select high-leverage programs reach 85% with roughly a 700+ score. On a cash-out refinance, most of the network tops out around 75% LTV, with about six months of seasoning common. Credit matters too. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Reserves commonly run around six months of PITIA, stepping up to about nine months on loans above $1,500,000.
A larger down payment lowers the monthly obligation and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
One pattern shows up often in deal flow. The owner of a long-held rental has plenty of equity but a thin ratio, because the rent never moved. The fix is almost always on the lease side, and it is cheaper to solve before the file is submitted than during review. For the complete picture of how these programs fit together, see the complete DSCR loans guide.
What Passing the Ratio Doesn’t Tell You
Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. A long-held tenant at a low rent may look steady on paper, yet the owner could still be carrying a thin real margin.
Common mistakes with legacy tenants:
- Signing a discounted lease just to show the unit filled. It locks in the lower figure.
- Pushing rent beyond what comparables support. The appraiser still caps the number at market.
- Relying on informal side arrangements. Underwriting counts what the paperwork and bank records show.
- Assuming tenure counts. A long tenancy shows stability. It does not raise rent used for lender review.
Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Does a below-market lease block a DSCR loan?
No. It lowers the ratio, because most programs credit the lease rent when it is under market. Whether the file still works depends on how far below market the lease sits, the leverage you want, and the program. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
Can I raise rent in the middle of a fixed-term lease?
Generally not, unless the lease allows it or the tenant agrees to an amendment. Month-to-month tenants can usually receive an increase with proper notice, subject to local rent rules. Check your lease and local law before sending anything.
Does an above-market lease help my ratio?
No. Most programs credit the lower of lease rent and the appraiser’s market rent, so a rent above market earns no extra credit. The ratio is built on the market figure instead.
What if my tenant is month-to-month?
Many programs lean toward market rent when there is no lease term, with payment history as support. That can help a below-market file. A few lenders still use actual rent, so confirm the program treatment before you assume.
Do refinances treat the gap differently from purchases?
Sometimes. Treatment varies by program, and some lenders handle the two the same way. On a cash-out refinance, coverage is tested against the new, larger obligation, which can tighten the ratio further.
