The Quick Read: When your tenant pays less than market rent, the signed lease usually becomes the ceiling on the rent a lender counts, so your file needs to prove that lease cleanly. Most programs take the lower of the lease rent and the appraiser’s market rent. That is a lender convention, not a federal rule. Build the file around the lease, proof of payment, and the appraisal rent schedule.
- A below-market lease typically lowers the coverage ratio even when the property’s value is strong.
- The appraiser’s market rent does not drop because your tenant pays less. The lender compares the two figures.
- A signed lease, bank-deposit proof, and a rent roll for 2-4 units form the core package.
- Disclose concessions such as free months or credits, because they reduce effective rent.
- Clearing 1.00 coverage is not the same as positive cash flow.
Picture a rental where the previous owner let a long-term tenant sit at a friendly rent. The home is worth plenty. The rent is not. That gap is what this article is about, and the paperwork you assemble decides how cleanly the lender can read it.

Key Terms Defined
DSCR (debt service coverage ratio) is the property’s qualifying monthly rent divided by its monthly obligation. A 1.00 ratio means rent equals the payment.
PITIA is principal, interest, taxes, insurance, and association dues. It is the payment side of the ratio.
rent used for lender review is the rent figure the lender actually plugs into the ratio.
In-place lease rent is what the tenant is contractually paying today.
Market rent is the appraiser’s opinion of what the property would rent for, built from comparable rentals.
Rent schedule is the appraisal form that reports market rent. Form 1007 covers single-family and condo units, and Form 1025 covers 2-4 units.
Rent roll is a unit-by-unit list of tenants, rents, and lease dates.
Concession is anything that lowers what the tenant really pays, such as a free month or a rent credit.
How Underwriting Treats a Below-Market Lease
Underwriting treats a below-market lease as a cap. The lender compares the lease rent with the appraiser’s market rent, and on most files the lower number wins. When your lease sits under market, the lease number goes into the ratio.
No regulator sets this rule. DSCR loans are business-purpose investor products, so each lender writes its own rent treatment. Across the wholesale network Lendmire places files with, the lower-of approach is the most common, and a few lenders will allow a variance when a current lease exists. That variance is more often used when the lease is above market. Do not assume it helps you here.
Here is the sequence a file follows.
1. Lease intake. The file collects the executed lease and any amendments. The lease must state the rent and the term.
2. Appraisal. The appraiser reports value, which drives LTV. The appraiser also reports market rent on the appropriate rent schedule form. The appraiser does not know your tenant, so a low lease does not pull the market rent down.
3. The lower-of comparison. A below-market lease becomes the rent used for lender review. On 2-4 units, each unit runs through the rent roll.
4. Coverage math. Rent used for lender review is divided by PITIA. Taxes and insurance do not shrink when rent does, so a modest rent shortfall can cut the supportable loan by more than the percentage gap.
5. Program test. The ratio meets the program’s coverage requirement, or it does not. Where many select programs start at 1.00, a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
Rent and value are separate tests. A property can carry plenty of equity and still be capped by rent. The strongest files clear both: enough equity and enough rental coverage.
Who Writes the Rent Number?
The appraiser estimates market rent, and the lender decides how income counts. McKissock, an appraiser-education provider, explains that Form 1007 estimates monthly market rent from comparable one-unit rentals. On a refinance it is used alongside lease agreements or traditional personal-income documentation, and income ultimately falls under the lender’s scope.
The form names come from the agency world. Fannie Mae’s Selling Guide lists Form 1007 as the single-family comparable rent schedule, and its appraiser update confirms it is required there only when rental income qualifies a one-unit investment property. That is contrast, nothing more. DSCR files borrow the form names, not the agency rules.
Lease Status Changes What the File Leans On
How the lease stands today matters as much as the rent itself. The table shows the usual pattern, though each lender’s overlay can shift it.
| Lease status | Rent the file usually leans on | What the file needs |
|---|---|---|
| Fixed term, current | Lower of lease or market | Signed lease, deposit proof |
| Month-to-month | Often market rent | Lease history, payment proof |
| Expired | Often market rent | Renewal or holdover evidence |
| Vacant | Market rent, program permitting | Appraisal rent schedule |
| 2-4 units | Unit-by-unit test | Rent roll plus leases |
The month-to-month and vacant rows reflect common practice rather than a published rule. Some lenders treat them differently, so confirm before you assume.
The Documentation Package for a Below-Market Tenant
Start with the lease. Then prove it is real, current, and complete. A below-market lease invites one natural question: is this a genuine arrangement or an incomplete record? Your package should answer it before anyone asks.
- Signed fixed-term lease with every amendment, showing names, rent, term, and signatures.
- Proof of rent paid. Bank deposits that match the lease amount are the cleanest evidence.
- Rent roll for 2-4 units, reconciled to the leases.
- Concession disclosure. Free months or credits lower effective rent, even when the stated rent looks fine.
- Appraisal rent schedule, which the lender orders as part of the file.
- Optional cover memo. One page explaining why the rent is below market, such as a long tenancy, and what you plan to do about it.
These pieces are standard practice, not a published rule. A short memo costs you nothing and removes guesswork.
Lease clauses an underwriter actually reads
Underwriters look for a few things in the lease itself:
- Parties and property named exactly as they appear elsewhere in the file.
- Rent amount, due date, and term.
- Renewal and escalation language, since scheduled increases are not credited before they take effect.
- Any bundled utilities or services, because rent that includes them is worth less than it looks.
- Signatures from every party.
Names matter more than people expect. If the tenant on the lease differs from the payer in the bank records, expect questions. If an LLC owns the property, subject to lender program eligibility, the entity papers should match the landlord on the lease.
Worked Example: Same Property, Three Versions
The numbers below are modeled assumptions, expressed only as ratios. Picture a rental that, at market rent, covers its monthly obligation at roughly 1.25x.
Version one: as-is. The tenant pays about 15% under market. The lease governs, so rent used for program review falls by that margin. Coverage drops to roughly 1.06x. Because taxes and insurance stay put, the ratio moves one-for-one with rent, and the supportable loan shrinks accordingly.
Version two: renewed at market. The tenant signs a renewal at documented market rent before the appraisal. Coverage returns to about 1.25x, which opens better pricing and leverage tiers.
Version three: lower leverage. The lease stays as it is, and you borrow less. The payment shrinks, so coverage lifts back above where version one landed. A larger down payment can lift the ratio, but it never erases leverage caps, credit floors, or reserve rules.
If version one fell under 1.00, a select-lender path below 1.00 exists, with leverage and terms adjusted. Qualification stays subject to lender guidelines, credit review, and property review.
Clearing a coverage floor is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, and utilities sit outside the ratio.
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.
Your Options When the Lease Is Low
You have four moves, and each has a cost.
1. Renew at market before the appraisal. This works when the tenant agrees and the market supports the rent. Get the renewal signed and documented. A promised increase does not count until it takes effect.
2. Raise rent on a month-to-month tenancy. This only works where local landlord-tenant rules allow it, and those rules are local. Check them before you send a notice.
3. Borrow less. On a refinance, taking less cash out protects the ratio. Cash-out proceeds and loan size are the most exposed when rent runs low.
4. Shop the structure. Some select lenders review rent differently, and sub-1.00 programs through select lenders in the network adjust leverage and terms. Interest-only periods through select lenders can also reduce the payment side of the ratio.
For the strategy side of that choice, Lendmire’s piece Keep a Below-Market Tenant vs. Re-Lease at Market for a DSCR Refinance walks through the tradeoffs. For a primer on how the loan works overall, see the complete DSCR loans guide.
Where the General Rule Bends
Subsidized tenants. Section 8 voucher rent is capped at the reasonable rent. Under 24 CFR Part 982, reasonable rent cannot exceed rent for comparable unassisted units. HUD’s rent reasonableness guidebook describes it as the lower of the rent charged to unassisted families or the payment standard. Whether a program counts contract rent or market rent is lender-specific. Ask first.
Related-party tenants. Policies differ. Some programs bar them, some allow them with closer review, and the borrower’s own household can never occupy the property. Document any family lease as carefully as an arm’s-length one.
Short-term rentals. Form 1007 documents monthly rent only, and appraisers cannot multiply a nightly rate by 30. Short-term income follows a separate path. On STR collateral, expect a 640+ score, about 12 months of hosting history, and a 1.00 coverage floor on purchases, with purchase leverage up to 75% LTV. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Concessions. A lease showing a healthy rent but two free months is not a healthy lease in the ratio. Disclose it.
Disputing a low appraisal rent. Do not count on it.
Common Mistakes
- Modeling on the asking rent instead of the signed lease.
- Counting a future increase before it starts.
- Collecting rent in cash with no deposit trail.
- Assuming a high lease raises the loan. Market rent caps an above-market lease.
What Leverage and Credit Look Like on These Files
Typical purchase leverage runs 75%-80% LTV on an investment property, with select high-leverage programs reaching 85% LTV with roughly a 700+ score. Cash-out refinances top out around 75% LTV on standard rentals, with about 6 months of seasoning common. Most programs want around a 660 score, a 620 floor exists in parts of the network, and 700+ unlocks the strongest tiers. Reserves commonly run about 6 months of PITIA, stepping up to about 9 months above $1,500,000. Standard programs reach $3,000,000. All of this varies by lender and file, and none of it is a commitment to lend. DSCR loans are designed for non-owner-occupied investment properties and are reviewed differently from a standard owner-occupied mortgage.
Manufactured homes, log homes, and barndominiums are not offered in these programs.

Frequently Asked Questions
Does a below-market lease automatically hurt my DSCR?
Usually, yes, when the lender counts the lower of lease and market rent. The lease becomes rent used for eligibility review, so coverage falls even if value is strong. A lender that allows a variance may treat it differently, but variances tend to help above-market leases more.
Can I just raise the rent before applying?
Sometimes. On a month-to-month tenancy you may be able to serve a notice, but local rules govern that. A signed renewal at documented market rent is cleaner than a verbal agreement, and underwriting generally does not credit an increase before it takes effect.
Does the appraiser lower market rent because my tenant pays less?
No. The appraiser builds an independent opinion from comparable rentals. The lender then decides how to use it against your lease.
What if the tenant is month-to-month or the lease expired?
Many lenders lean on market rent in those cases, though practice varies. Gather rent payment history and any renewal evidence so the file is complete either way.
Is clearing 1.00 the same as positive cash flow?
No. DSCR compares rent to PITIA only. Repairs, vacancy, management, and utilities sit outside the calculation, so run your own full cash-flow numbers.
