The Quick Read: When a tenant comes with the property, a DSCR lender typically counts the lower of two numbers: the rent on the in-place lease or the appraiser’s market-rent opinion. Across the network, most programs work this way, though a few lenders lean on actual rent instead. A lease above market adds nothing, and a legacy lease below market caps your coverage.
- No federal rule sets this. It is a lender and program convention.
- A lease above market never lifts your ratio, because the appraisal caps the rent.
- A below-market legacy lease can limit your loan before your equity does.
- Expired, month-to-month, or unwritten tenancies are usually workable but make a weaker file.
- Clearing 1.00 coverage is not the same as positive cash flow.
Say you are buying a fourplex with tenants who have lived there for years. The rent they pay is the rent you inherit. It may not be the rent the lender uses. This article walks through which number goes into the ratio, why, and what you can do when the old lease drags it down.
What Carries Over When Tenants Come With the Property
A sale generally does not end a lease. The buyer takes the property subject to the existing tenancy, so the rent, the term, and any concessions carry over. LawDepot’s guide to selling with tenants and Super Lawyers’ explainer on landlords who sell both describe it this way. Details vary by state, and this is general information, not legal advice.
Month-to-month tenancies work differently. A new owner is bound by the existing arrangement but can usually end a month-to-month tenancy with proper notice, and ReadYourLease’s overview of renters’ rights on a sale notes that notice rules are state-specific. The same source says a new owner cannot raise rent early on a fixed-term lease.
“Inherited” can also mean the property itself came through an estate. An estate sale does not end the lease either, per ReadYourLease’s guide for sales of occupied buildings.
Landlord Rent vs. Lender Rent
The rent you may charge and the rent a lender will count are two different questions. Mixing them up causes most of the surprises.
| Question | Landlord view | Lender view |
|---|---|---|
| What rent applies? | What the lease allows | Lower of lease or market rent |
| Above-market lease | Collect every dollar | Extra rent adds nothing |
| Below-market lease | Locked in until renewal | Lease rent caps coverage |
| Tenant history | Shows stability | Does not set the number |
DSCR is the qualifying monthly rent divided by the full monthly payment, meaning principal, interest, taxes, insurance, and any HOA dues (together called PITIA). DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. They are not agency loans, so no agency rule dictates the rent figure.
How the Lease-vs-Market Comparison Works
Here is how underwriting treats an occupied property, step by step.
1. Tenant status is identified. Fixed-term lease, expired or holdover, month-to-month, or no written lease.
2. Documents are gathered. The executed lease shows rent, term, and parties. Bank statements show rent actually landing. The two must agree.
3. The appraisal is ordered with a rent schedule. The appraiser picks comparable rentals, adjusts for differences, and concludes a market rent. Value drives LTV. Rent drives coverage.
4. The rent is selected. Most programs we place files with use the lower of the lease and the market-rent opinion.
5. Coverage is tested. The selected rent is divided by PITIA on the new loan. On a cash-out, the payment rises, so coverage falls.
6. The outcome is decided. When lease and market rent differ, that gap is what moves the result.
The market-rent opinion usually follows an agency-style format. For a single-family rental, Fannie Mae’s Form 1007 is how an appraiser documents monthly market rent. For two to four units, the equivalent is Form 1025. DSCR loans borrow the format, not the rules. Form 1007 is built for monthly rent, not nightly rates, so short-term rentals follow a different documentation track.
The comp grid also lists concessions. Fannie Mae’s form instructions say concessions should be adjusted to the market, not to the subject. In practice, free-rent deals in the comps pull the indicated market rent down.
Why the lower-of rule? It stops an inflated friendly lease from overstating the property. It also keeps a stale below-market tenant from understating it. One brief contrast: a conventional loan can count rental income from a lease, Form 1007, or an appraiser’s opinion on an unrented property, per the Fannie Mae Selling Guide on rental income. That is a conventional-loan rule. It does not govern DSCR files.
For the full picture of how these loans work, see the complete DSCR loans guide.
Worked Example: A Fourplex With One Legacy Lease
Consider a hypothetical fourplex. The numbers below are modeled assumptions, not market data, and the example avoids dollar amounts on purpose. Everything is expressed as lease rent compared with market rent.
| Unit | Lease vs. market | Rent used |
|---|---|---|
| Unit 1 | Lease equals market | Either |
| Unit 2 | Lease above market | Market |
| Unit 3 | Lease below market | Lease |
| Unit 4 | Long-tenured, well below market | Lease |
Unit 2’s extra rent disappears. Unit 4’s discount stays. The building total ends up below what the market-rent column alone would produce. Say that gap moves the building from roughly 1.25x coverage to about 1.10x. That is still above 1.00, but it may change which pricing and leverage tier a lender offers.
Now push it further. If the same gap pushed coverage under 1.00, options exist. A sub-1.00 path is available through select lenders in the network, with leverage and terms adjusted. A lender could also review interest-only structuring. Neither is automatic, and qualification stays subject to lender guidelines, credit approval, and property review.
Run it as a unit-by-unit rent roll. Every unit gets reconciled. One stale lease can drag the whole building.
Tenancy Types: What Lenders Typically Want
These are network conventions and vary by program. Treat them as typical, subject to lender guidelines.
| Situation | Typical treatment | Risk to the file |
|---|---|---|
| Fixed-term lease | Lower of lease or market | Low if rent is proven |
| Expired or holdover | Written rent plus payment proof | Weaker file |
| Month-to-month | Not a block on its own | Some programs look harder |
| No written lease | Market rent, weaker evidence | A simple lease is the fix |
| Related-party rent | Capped at market | Closer review possible |
| Vacant | Appraiser’s market rent alone | Depends on the property |
Month-to-month is where programs differ most. Some lenders substitute market rent for the lease. A few lean on actual rent instead. This is a real program-to-program difference, so ask before you choose a lender. Subsidized-rent units may also be handled differently, and the same advice applies: ask first.
Documents to Assemble
Lenders want proof that the rent on paper is the rent in the bank. Gather these early:
- The executed lease with every amendment.
- Bank statements or a ledger showing rent deposits.
- On a purchase, the seller’s lease and rent roll.
- Security deposit records.
- Tenant estoppel certificates, where obtainable.
An estoppel certificate is a signed statement from the tenant confirming rent, deposit, term, and any modifications. It exists to prevent post-closing surprises, such as a verbal side deal nobody told you about. Lenders may request one, and a lender’s required form can be more detailed than your own. Tenants are not parties to the purchase contract and can decline to sign, though some leases require it.
When the Property Came Through an Estate
An heir who inherits a rented property faces a different set of questions. Title, authority to collect rent, and a traceable rent account all matter. If the estate has not transferred title, who has the legal right to collect and document rent? Keep the rent in one traceable account so deposits tie back to the lease. Related-party friction can show up when a family member lives in or rents the property, since friendly rent is capped at market. Check with an estate attorney on authority before you refinance.
Should You Raise Rent Before Applying?
Sometimes, but rarely as a quick fix. The lease and local law limit what you can do, and a fixed-term lease generally cannot be repriced early. Three practical moves exist:
- Renew at documented market rent before the appraisal is ordered, if the tenant agrees.
- Supply recent signed comps the appraiser did not use.
- Wait and reprice at renewal, then refinance.
The tradeoff is vacancy risk. A rent bump that triggers a move-out can cost more than the coverage gain. This one is a genuine toss-up, and the answer depends on how thin the file is. If coverage clears comfortably, leave the tenant alone. If it misses a leverage tier, a renewal at market may be worth a conversation.
Run pro forma numbers on market comps, not the seller’s rent roll. The rent you buy is the rent you inherit, and your offer price should reflect it.
Where Program Terms Fit In
Program terms shape how much a rent gap matters. Across the network, 1.00 is where select programs start, and stronger ratios open better pricing and leverage. Purchases typically land at 75%–80% LTV on an investment property, and cash-out on a rental tops out around 75% LTV, subject to lender guidelines. Most programs want a credit score around 660, with a 620 floor in parts of the network and 700+ for the strongest tiers. Reserves commonly run about 6 months of PITIA, stepping up to about 9 months above $1,500,000.
A bigger down payment can lift coverage by shrinking the payment. It never erases leverage caps, credit floors, or reserve rules. And passing the coverage test is not positive cash flow. Repairs, vacancy, management, and capex sit outside the calculation.
Short-term rentals follow separate rules, covered in Lendmire’s piece What Counts As Short Term Rental Income For A Lender?.
Key Terms Defined
Legacy lease: An older lease at a rent below what the market now supports.
Market rent: The monthly rent the appraiser concludes from comparable rentals.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly payment used in the ratio.
Holdover: A tenant who stays after the lease term ends, usually paying the same rent.
Estoppel certificate: A tenant-signed statement confirming the lease facts.
LTV: Loan-to-value, the loan amount as a percentage of the property’s value.
Frequently Asked Questions
Can a lender count my tenant’s old lease rent?
Yes, when it is the lower figure. Most programs compare the lease rent with the appraiser’s market rent and use whichever is lower. An old lease at a below-market rent will therefore set your number.
What if my tenant is month-to-month?
It is usually workable. Month-to-month is not a block on its own, though some programs look harder at the lack of a term. Written proof of the rent and the payment history helps.
Does a lease above market rent boost my ratio?
No. The appraisal caps the rent, so extra rent above market adds nothing to coverage.
Can I raise rent right after buying to improve my ratio?
Generally not on a fixed-term lease. Check local rules before planning around a rent increase.
Do tenants have to sign an estoppel certificate?
Not necessarily. Tenants are not parties to your purchase contract and can decline, although some leases require one. A lender may still ask for it, so raise it early.
