The Quick Read: When you buy a rental with a tenant already in place, the lease stays with the property, but the lender decides which rent counts. On most files that figure is the lower of the signed lease or the appraiser’s market rent, so an above-market lease earns no extra credit and a below-market lease pulls your coverage down. The rule is a lender and program convention, not a law.
- The tenant does not have to move, re-qualify, or sign a new lease when you buy.
- Most programs in a wholesale network count the lower of the lease or the appraiser’s market rent.
- A lease alone does not prove rent. Lenders want payment proof that matches it.
- Clearing 1.00 coverage is not the same as positive cash flow.
- Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted.
“Inherited tenant” here means a tenant who comes with the property when you buy it or otherwise acquire it. Inheriting a property through an estate is a separate legal path and is not covered here.

What Happens to the Tenant and the Lease When You Buy?
The lease transfers with the property. Per RentalRealEstate.com, in most U.S. jurisdictions a valid lease is an interest in the real property. The buyer generally steps into the landlord’s position and takes the property subject to the tenancy.
A fixed-term lease binds you for the remaining term at the signed rent, even if that rent is below market. A month-to-month tenancy also transfers. You can typically end it only with the notice your state requires, and some cities add just-cause rules that limit ending a tenancy at all.
You do not need a new lease at closing. That is a common assumption, and it is wrong.
Which Rent Does a DSCR Lender Count?
Across our wholesale network, an occupied property is typically reviewed on the lower of the signed lease or the appraiser’s market rent. That number is divided by the full monthly housing payment (principal, interest, taxes, insurance, and any HOA dues, known as PITIA) to produce the DSCR.
Here is how that plays out:
- Lease equals market: the rent counts as is.
- Lease above market: the excess is ignored. You are capped at market.
- Lease below market: the lease becomes the rent counted, and coverage drops.
- Vacant property: the appraiser’s market rent stands alone.
Where does the market number come from? The appraiser prepares a rent schedule. For a single-family investment property that is the Fannie Mae Form 1007 / Freddie Mac Form 1000, which asks for the indicated monthly market rent based on comparable rentals. For two to four units, the rent analysis is built into the multifamily appraisal form (Form 1025). DSCR loans are not agency loans. These forms simply supply the appraisal document and the vocabulary.
Why the lower figure? A lender is protecting against two risks. A lease above market may not be repeatable when the tenant leaves, and a lease below market is the income you will actually collect until it ends. Counting the lower number covers both.
No regulator sets these rules. DSCR underwriting is lender and program convention, so treatments vary. A few lenders in the network will lean on the actual lease for a seasoned tenant. Others prefer market rent whenever the lease looks thin.
Key Terms Defined
DSCR (debt service coverage ratio): the qualifying monthly rent divided by the full monthly housing payment.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly obligation on the property.
In-place rent: the rent the current tenant pays under the lease.
Market rent: the rent an appraiser concludes the unit would earn, based on comparable rentals.
Estoppel certificate: a statement the tenant fills out and the landlord confirms, listing lease terms, rent, and deposit. It confirms facts and does not transfer the lease.
Assignment of leases and rents: the closing document that moves the landlord’s rights under the leases to the buyer.
Seasoning: the time a tenant has been in place paying rent, which strengthens the file.
How Do Inherited-Tenant Situations Change the Rent?
Each lease situation has a typical treatment. Lender-by-lender differences apply, so read this as the common pattern.
| Tenant situation | Rent typically counted | Common fix |
|---|---|---|
| Below-market long-term lease | The lease | Renewal at documented market rent |
| Above-market lease | Market rent | None needed; excess ignored |
| Month-to-month or expired | Often market rent | Fixed-term renewal at market |
| New lease just signed | Lower-of test | Proof of deposit and first payment |
| Related-party tenant | Market rent | Closer payment history review |
| Tenant not paying | Unit treated as transitional | Resolve, re-lease, then apply |
| 2–4 units | Unit-level rents | Clean rent roll matching leases |
The below-market lease is the classic value-add trap. The lease wins the comparison, so your coverage lands below the property’s true potential. If the tenant agrees, a renewal at documented market rent before the appraisal can fix it. A discounted lease signed just to fill a unit can drag the counted rent down instead.
Month-to-month and expired leases are weaker evidence. Market rent often governs, and some lenders apply a stress factor. Legally, a month-to-month tenancy can usually be ended with state notice, but the lender’s treatment and the legal reality are different questions.
A new lease signed just before purchase usually counts as in-place rent under the lower-of test. Expect to show the tenant paid the deposit and first month’s rent.
A related-party tenant gets market rent instead of the lease rent, with a closer look at payment history. A relative living in your own household is owner occupancy, and that is not eligible for a DSCR loan.
A tenant who stopped paying, or an eviction filing, makes the unit transitional. The usual path is to resolve the tenancy, re-lease at market, then apply.
Two to four units are tested unit by unit. A rent roll supports the rents, and one weak unit drags the total. The roll and the leases must tell the same story for every unit, or the file stalls.
What Documents Prove the Rent?
A lease alone does not qualify the rent. Lenders want deposits that match it. A typical file for an occupied rental includes:
- the signed lease and any modifications
- proof of payment, such as bank deposits matching the lease amount
- a rent roll for two to four units
- the appraisal with the rent schedule
At the contract stage, ask the seller for the lease documents and a tenant estoppel certificate. It typically captures the occupancy date, any written modifications, verbal side agreements, the term, current rent, and the security deposit. It exists to prevent surprises after closing.
Keep the two documents straight. The estoppel confirms terms and deposit. The assignment of leases at closing transfers the landlord’s rights. A tenant is not obligated to sign an estoppel, though it is worth asking, as a law-firm guide on buying property with existing tenants points out.
Deposits need attention too. The deposit transfers to the new landlord at sale. Steadily warns that a buyer can inherit liability for deposit money never received, and it recommends a tenant-by-tenant accounting at closing. State procedures vary, so treat those as local rules, not national ones.
Also check how past rent was paid. Informal cash payments leave a thin trail. A lender wants traceable deposits, so sort that out 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.
A Worked Example: Same Property, Two Leases
Run this as a modeled comparison, not market data. Picture two identical duplex units with the same appraiser market rent and the same full monthly payment. Assume the property clears around 1.25x when the lease matches market.
Now swap in a lease sitting roughly 12% under market. The lower-of rule counts the lease, and coverage falls toward 1.10x. Nothing about the building changed. The tenant’s old paper changed the answer.
Flip it. Say the lease sits well above market. Coverage stays near 1.25x, because the lender caps rent at market. You get no credit for the extra.
Value and rent also set separate loan limits. Value sets one ceiling, rent sets the other, and the smaller one becomes your loan size. A below-market lease can therefore shrink proceeds right at closing, even when market rent would support more.
Now the part that trips people up. DSCR compares rent to PITIA only. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. Do not read a passing ratio as profit.
Which Program Numbers Apply to These Files?
Treat these as typical ranges from select programs in our network, subject to lender guidelines. Not a commitment to lend.
- Purchase leverage: most files land at 75%–80% LTV on an investment property purchase.
- Cash-out refinance: tops out around 75% LTV on a standard rental.
- Coverage: 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
- Credit: a 620 floor exists in parts of the network, most programs want about 660, and 700+ opens the strongest tiers.
- Reserves: commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000.
- Loan size: up to $3,000,000 on standard programs.
A bigger down payment can lower the payment and lift the ratio. It does not erase leverage caps, credit floors, or reserve rules. The strongest files clear both tests: enough equity and enough rental coverage. Manufactured homes, log homes, and barndominiums are not offered in these DSCR programs.

Diligence Before You Make the Offer
In practice, files with an inherited tenant go smoothly or stall based on what you check before contract. Pull comparable rents first. Compare the lease rent to that market figure. If the gap is large, price it into your offer, because the lease will set your counted rent.
Then read the lease for term, rent, deposit, renewal options, sale clauses, and any right of first refusal. Collect the estoppel. Confirm payments in bank records. Where a renewal at market rent is possible and the tenant is willing, plan it before the appraisal is ordered.
One practitioner pattern worth knowing: the biggest surprises come from leases that look strong on paper but have no matching deposit trail, and from rent rolls that disagree with the leases. Fix those before submission, not after the lender flags them.

Frequently Asked Questions
Do I need a new lease with the tenant when I buy?
No. The existing lease transfers with the property, and the tenant does not need to re-qualify or sign anything new. You step into the landlord’s position under the current terms. A fixed-term lease binds you for its remaining term.
Will an above-market lease raise my DSCR?
No. Most programs count the lower of the lease or the appraiser’s market rent, so the excess is ignored. Coverage is measured against market, not the premium the tenant happens to pay.
What if the tenant is month-to-month?
Lenders generally treat it as weaker evidence, and market rent often governs. Some apply a stress factor. A fixed-term renewal at market rent can simplify the file, subject to lender guidelines.
Does an estoppel certificate transfer the lease?
No. It confirms facts like rent, term, and deposit. The assignment of leases and rents at closing transfers the landlord’s rights.
Can I count rent from a family member who rents the unit?
Typically market rent applies instead of the lease rent, with closer review of payment history. A relative living in your own household is owner occupancy and is not eligible.
