The Quick Read: On most DSCR refinances, a signed lease that sits below the appraiser’s market rent becomes the rent the lender counts. Keeping that tenant holds coverage and loan size down. Re-leasing at a documented market rent lifts both, but it costs you turnover risk and timing. The right choice depends on the size of the gap, the cushion already in the file, and whether the tenant will agree.
- A below-market lease usually caps the rent used for lender review. An above-market lease is usually capped at market rent.
- A rent shortfall shrinks the loan by more than its own percentage, because taxes and insurance stay fixed.
- Keeping the tenant fits small gaps, strong coverage, and files where you can take less cash out.
- Re-leasing fits large gaps, thin coverage, and tenants who are open to a reset or already leaving.
- Any new lease has to be signed and documented before the file goes to underwriting.
Here is the honest answer on who each option is for. Re-lease at market if the legacy rent is the only thing holding your loan back and a reset is realistic.

DSCR (debt service coverage ratio) is the test behind these loans. It divides the property’s monthly rent by its full monthly housing payment. Because the loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, the rent figure matters more than usual.
Side-by-Side
The table shows the structural differences. It is a decision aid, not a ranking. Program details vary by lender, borrower, and property.
| Factor | Keep the Below-Market Tenant | Re-Lease at Market |
|---|---|---|
| Rent the lender counts | Typically the lower of lease or market rent | Documented market rent, up to the appraisal |
| Effect on coverage | Stays lower while the lease runs | Rises if the new rent is supported |
| Effect on loan size | Limits the maximum loan when rent is the binding test | Can raise it |
| Documentation | Lease, proof of payment, rent roll if multi-unit | New signed lease, deposit proof, rent comps |
| Property types | Standard eligible 1-4 unit rentals | Same; manufactured, log, and barndominium homes are not offered |
| Entity vesting | Individual or LLC, subject to lender program eligibility | Same treatment |
| Reserve expectations | Set by the loan, not by the lease choice | Same |
| Main risk | Coverage and proceeds stay constrained | Vacancy, make-ready cost, tenant loss |
| Timing | Works with the current lease term | Lease must be in place before underwriting |
The reserve and entity rows match on purpose. Choosing a lease strategy does not change reserve rules or vesting. Across Lendmire’s wholesale network, reserves commonly run around 6 months of the full housing payment and vary by lender, leverage, loan size, and transaction type. Loans above $1,500,000 typically step up to about 9 months, and conservative rate-and-term files at modest leverage can see reserves waived.
Key Terms Defined
PITIA: principal, interest, taxes, insurance, and any association dues. It is the full monthly housing payment that rent is measured against.
Market rent: the monthly rent the appraiser concludes the unit would command today, based on comparable rentals.
Legacy lease: a long-running lease signed at a rent that has not kept pace with the market.
Loss-to-lease: the gap between what a unit rents for and what it could rent for at market.
Rent roll: a unit-by-unit list of tenants, rents, and lease dates for a multi-unit property.
Seasoning: the waiting period a lender wants after you buy a property before certain refinances. About 6 months is the common expectation for a cash-out refinance, which pulls equity out as cash.
How the Lender Picks the Rent
No regulator sets this rule. Each program writes its own convention, and the common one is the lower of the signed lease or the appraiser’s market rent. If the lease is below market, the lease controls. If the lease is above market, market rent controls. If the property is vacant, market rent alone is used.
The market-rent number comes from the appraiser. The rent schedule form is prepared by the appraiser as an attachment for a single-family investment property. Fannie Mae’s appraiser guidance describes the same form as documenting estimated monthly market rent. DSCR programs borrow the format. They do not follow agency rules.
The appraiser does not guess. Blueprint explains that appraisers choose comparable rentals, adjust them, and reconcile to one supported monthly figure. That is why a lease priced far above comps does not help you.
Two points matter for the decision. Value drives leverage, and market rent drives coverage. A property with plenty of equity can still be limited by a cheap lease. Rent also sits on top of a fixed cost stack, so a rent shortfall shrinks the loan by more than its own percentage. In a simple Lendmire illustration, a 10% rent shortfall cuts the maximum loan by roughly 13% when rent is the binding limit.
A Modeled Example Across Both Options
These are modeled assumptions, not market data. Say a rental clears about 1.15x coverage at market rent. The tenant pays 10% under market.
- Keep the tenant: counted rent drops 10%, so coverage lands near 1.03x. That is still above 1.00, which is where many select programs start, but the cushion is thin. The loan limit is also lower.
- Reprice to market: coverage returns to about 1.15x if the new rent is supported by comps and documented.
- Larger gap: if the tenant pays 20% under market, coverage falls to roughly 0.92x. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Eligibility stays subject to lender guidelines, credit approval, and property review.
Clearing 1.00 does not mean the property makes money. The ratio compares rent to the housing payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
When Keeping the Below-Market Tenant Is the Better Fit
Keeping the tenant is the stronger play when the lease gap is small and the file has room. A modest discount rarely moves coverage enough to change eligibility. If the ratio clears the program floor with margin, the legacy lease may cost you nothing at all.
It also fits when turnover would be expensive. A turnover has four main costs: vacancy, make-ready work, leasing, and screening. Here is the break-even math. Divide the turnover cost by the monthly rent increase to get the payback period. Assume turnover costs about two months of market rent and the reset adds 10% to monthly rent. Payback then runs about 20 months. If the tenant is stable and the property needs work, that payback can be hard to justify.
Keeping works well when you can take less cash out. A cash-out refinance tops out around 75% LTV on a standard rental across most of the network. LTV is the loan amount divided by the property value. If the lease limits proceeds, a smaller draw can still meet your goal. You also keep a tenant who pays on time, which a vacancy cannot promise. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
It is also the only choice when the tenant refuses and the lease has no escalation clause. A fixed-term lease generally cannot be raised mid-term. Local rent rules may also limit how far you can move. NMHC’s rent regulation research separates rent control, which sets absolute caps, from rent stabilization, which uses formula-based increases. It also describes vacancy decontrol, which lets rents reset between tenants. Check state and local law before you plan a raise.
When Re-Leasing at Market Is the Better Fit
Re-leasing is the better fit when the legacy rent is the only obstacle. If coverage sits near the floor, or below it, a documented market rent can change the file. It can also raise the loan limit if the property has equity.
It fits when the tenant is already open to a renewal at a higher rent. A step-up renewal avoids vacancy completely. It also gives you a signed lease that matches the appraiser’s comps. Timing is the key rule: finalize and document the lease before the file goes to underwriting, not after. The appraisal can come back with market rent anyway, so the lease must support it.
It fits large gaps. When the discount is deep, the coverage hit is real, and the payback on a turnover shortens. It also fits properties that need a refresh anyway, since a unit that needs work carries less extra cost when the tenant leaves.
One honest caution. Terminating a tenancy mid-process can backfire. A vacant unit is underwritten on market rent alone, but you lose the lease evidence and you carry the vacancy. If the tenant leaves and the unit needs work, you can end up with a vacant unit and a leaner loan than you started with. Plan the lease sequence before you apply.
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.
Documentation for a Clean Renewal or Re-Lease
Keep the packet simple. A lender wants proof that the rent is real and supported.
- A signed lease with current rent, term, and both parties’ signatures.
- Proof of payment, such as deposits or a tenant ledger.
- A rent roll for any multi-unit property.
- Rent comps or the appraiser’s rent schedule supporting the figure.
A rent that looks manufactured raises questions. A lease priced well above comps, signed late, or lacking payment history can draw extra scrutiny. Some programs also review leases with family members more closely, and a discounted family lease lowers the counted rent.
Multi-Unit and Portfolio Files
On a 2-4 unit property, the rule often applies unit by unit. Units above market get no credit for the excess, and units below market reduce the total. One legacy lease can drag the whole building. If you can only reprice one unit before the appraisal, start with the one with the biggest gap and the most willing tenant.
Portfolio loans add another wrinkle. Each property needs its own appraisal and a lease or supported market rent. In a pooled structure, a weak below-market property can pull on the group. Lendmire’s piece Refinancing a Rental Property With a Below-Market Lease: How the Market Rent Analysis Is Used covers that review in more depth.
If the Tenant Says No
You still have options. You can take less cash out, which fits the lower rent used for lender review. You can wait until the lease reaches a natural renewal date. You can add leverage or coverage in other ways, such as a larger down payment on a purchase. A larger down payment can lift coverage, but it never erases leverage caps, credit floors, reserve rules, or property eligibility. Credit matters here too. A 620 floor exists in parts of the network, most programs want around 660, and 700+ opens the strongest leverage tiers.
The strongest files clear two tests at once: enough equity and enough rental coverage. For a step-by-step look at fixing the lease before applying, see Lendmire’s guide How to Reset a Below-Market Lease Before a Super Jumbo DSCR Refinance.
Decision Matrix
| Situation | Leans Toward | Why |
|---|---|---|
| Small gap, strong coverage | Keep | Little to gain, turnover risk remains |
| Large gap, thin coverage | Re-lease | Rent is the binding limit |
| Tenant open to renewal | Reprice | Avoids vacancy |
| Tenant refuses | Keep, take less cash | Fixed-term lease is hard to raise |
| Local rent limits apply | Keep or step up | Legal limits cap the reset |
| Unit needs work anyway | Re-lease | Turnover cost is lower |
Common Mistakes
Modeling on the asking rent or the old lease instead of the appraiser’s figure is a common error. Forcing a raise that costs you the tenant is next. Renewing after the appraisal is another. Treating a coverage ratio as cash flow is the last.
The Verdict
Neither option wins on its own. Keeping the tenant protects your income stream and avoids vacancy, but it ties your rent used for lender review to a lease you signed long ago. Re-leasing raises coverage and loan capacity, but it only works if the new rent is supported and documented in time.
A useful rule: run both versions of the file before you decide. If the legacy lease still clears the program with margin, keep the tenant. If the lease is the only thing standing between you and your target loan, plan a documented reset, or take less cash and wait.

Frequently Asked Questions
Does a below-market lease hurt my DSCR?
Usually yes, because the lease is typically the rent counted when it sits below market rent. The ratio falls and the maximum loan shrinks. How much depends on the gap and on the program.
Should I raise rent before refinancing?
It depends on the gap and the tenant. A supported raise can lift coverage if the lease is signed and documented before underwriting. A raise that costs you the tenant can leave you with a vacant unit and a smaller loan.
What if my tenant is month-to-month or the lease has expired?
Treatment varies by program. Many lean on market rent with the lease as support, and a vacant property uses market rent alone. Confirm the approach before you apply.
Does it matter if I hold title personally or in an LLC?
Vesting does not change which rent counts. LLC-titled loans are subject to lender program eligibility, but the lease-versus-market rule works the same way.
Can a higher lease help me qualify?
No. An above-market lease is typically capped at the appraiser’s market rent, so a lease priced well above comps adds nothing.
