The Quick Read: A DSCR file qualifies primarily on property-level rental income covering the monthly obligation, subject to lender guidelines. The rent figure usually comes from the appraiser’s 1007 market rent or the signed lease, and many programs credit the lower of the two. An interest-only structure shrinks the payment side of the ratio, but it never changes the rent side.
- The appraiser’s rent opinion, not your pro forma, sets the numerator on most files.
- A leased property commonly credits the lower of lease rent or 1007 market rent.
- Interest-only helps the ratio only when the program tests the interest-only payment.
- The payment steps up when the interest-only period ends, and no principal has been paid by then.
- Clearing 1.00 is not the same as positive cash flow.
Investors tend to treat these two ideas as separate topics. They aren’t. The 1007 decides how much rent counts, interest-only decides how big the payment looks, and the ratio is simply one divided by the other. Understand both and you can predict, before you apply, whether a deal will clear.

What Does the DSCR Calculation Actually Measure?
The ratio divides qualifying monthly rent by the monthly obligation on the property. That obligation is PITIA: principal, interest, taxes, insurance, and any association dues. A result of 1.00 means rent equals the obligation. Above that, rent exceeds it. Below, it falls short.
Across the wholesale network Lendmire works with, 1.00 is where select programs start. It is a floor for specific programs, not a universal standard. Stronger ratios tend to open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. No-ratio structures also exist, available only through select lenders, generally for borrowers who already own a primary residence.
Here is the catch. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. A property can clear the ratio and still lose money in a slow month. Treat the number as a qualification test, not a profit forecast.
For the full program picture, the complete DSCR loans guide walks through leverage, credit, and reserves.
What Is the 1007 and Who Builds It?
The 1007 is the single-family comparable rent schedule. An appraiser prepares it as an attachment to the appraisal. The form lays out three comparable rentals, adjusts only for significant differences between those comps and the subject, and reconciles to an indicated monthly market rent.
The forms themselves, Fannie Mae’s and Freddie Mac’s, do not govern DSCR loans. DSCR programs borrowed the form because it is a standard, familiar way to document rent. The lender takes the appraiser’s figure and uses it as the numerator.
Two-to-four unit properties work differently. The rent analysis sits inside the small residential income property appraisal, commonly Form 1025, and is typically applied unit by unit.
The appraisal does two jobs at once. One value opinion sets the loan-to-value ceiling. One rent opinion sets the numerator. A single appraisal therefore controls both halves of the “enough equity and enough rent” test.
Which Rent Counts: The Lease or the 1007?
On most files in the network, the lower of the two counts. The table shows how that plays out.
| Scenario | Rent typically used | Why |
|---|---|---|
| Vacant or newly purchased | 1007 market rent | No lease exists |
| Lease below market | The lease | Lower figure governs |
| Lease above market | 1007 market rent | Market rent caps it |
| Month-to-month or expired | Usually lower-of logic | Documentation changes |
| Short-term rental | Program-specific evidence | 1007 is monthly rent |
A few programs use the higher of lease or 1007. That is a minority approach, and programs differ, so confirm which rent governs before you rely on either.
The above-market lease trap. An investor buys a property with a tenant paying well above market. The seller’s lease looks great. Underwriting caps the rent at the appraiser’s number, and the extra income adds nothing.
The below-market lease trap. A legacy rent, or a rent to a relative, can hold the file back even when the appraiser says the property could rent for more. Renewing a tenant at market before you apply often fixes this.
Short-term rentals. Fannie Mae’s appraiser guidance describes the 1007 as documenting monthly market rent for conventional lending. A nightly rate multiplied by 30 is not market rent. Programs that accept short-term income use other evidence, such as a hosting history. On the network’s short-term programs, expect a 640+ score, about 12 months of hosting history, and a 1.00 coverage floor on purchases. Purchase leverage tops out at 75%.
How Does Interest-Only Change the Math?
Interest-only shrinks the denominator. The rent never moves.
| Version | Payment side | Effect on ratio |
|---|---|---|
| Fully amortizing | Principal, interest, taxes, insurance, dues | Baseline |
| Interest-only | Interest, taxes, insurance, dues | Higher on same rent |
Monthly interest is the balance multiplied by the annual rate, divided by 12. Remove principal from the payment and the same rent covers a smaller obligation. Some practitioners call the result ITIA instead of PITIA.
Run it as a ratio. Say a property’s rent covers the fully amortizing obligation at about 0.95x. Switch to an interest-only payment on the same balance and the identical rent might cover it at around 1.1x. Those are modeled assumptions, not market data. The point is the direction: a borderline file can move above 1.00 without a single dollar of added rent.
Interest-only is available through select lenders in the network, along with extended terms such as 40-year structures. The spine of the network remains the 30-year fixed, and ARM structures exist for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed.
Which Payment Actually Gets Tested?
This is the question that decides whether interest-only helps. Programs split into two camps.
- Tested on the actual interest-only payment. The ratio improves, and a marginal file can clear.
- Tested on a fully amortizing payment. The borrower pays interest-only, but coverage is measured as if principal were included. Cash flow improves. The ratio does not.
Many investors assume interest-only always lifts the ratio. It doesn’t. It lifts the ratio only when the program tests the interest-only payment.
Reserves add a second wrinkle. Some programs test coverage on the interest-only payment but size reserves on a different basis. Reserves vary by lender, leverage, loan size, and transaction type, commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. Ask which payment drives each test, because the answer can differ between coverage and reserves.
What Happens When the Interest-Only Period Ends?
The payment steps up. At the end of the interest-only period, the unchanged balance amortizes over the shorter remaining term. A 30-year loan with a 10-year interest-only period becomes a 20-year amortization. The OCC‘s consumer guide on interest-only loans describes the same mechanic: interest only for a set number of years, then both principal and interest.
The recast risk is real. No principal has been paid down by then, and the new payment is higher than a standard amortizing loan would have been. An investor who qualified on a thin interest-only ratio should ask what the recast looks like on the same rent, and whether a refinance or rent growth is the plan. Interest-only is a tool for the early years of a hold. It is not a permanent fix for a property that doesn’t cover itself.
When the 1007 Comes in Low
A low rent figure can sink a ratio that looked fine on paper. Interest-only may rescue it, but only when the program tests that payment. If the program tests an amortizing payment, a low 1007 hurts and the structure can’t offset it.
Practical levers, in order of usefulness:
1. Hand the appraiser your own rental comps when the appraisal is ordered.
2. Renew a below-market lease at market before applying.
3. Challenge a low figure with competing comps if the report arrives light.
4. Add equity. A larger down payment lowers the payment and can lift the ratio.
That last lever has limits. More equity never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. On purchases, most files land at 75%-80% LTV, with select high-leverage programs reaching 85% at roughly a 700+ score. Cash-out refinances top out around 75% LTV, with about 6 months of seasoning the common expectation. Standard loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). All of this is subject to lender guidelines and individual underwriting.
Some property types fall outside the programs entirely. Manufactured homes, log homes, and barndominiums are not offered.
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.
Key Terms Defined
DSCR: Qualifying monthly rent divided by the monthly obligation on the property.
PITIA: Principal, interest, taxes, insurance, and association dues, the full payment side of a standard ratio.
ITIA: The same obligation with principal removed, used when an interest-only payment is tested.
Form 1007: The appraiser’s single-family comparable rent schedule, which produces an indicated monthly market rent.
Form 1025: The small residential income property appraisal form used for 2-4 unit rent analysis.
Recast: The step-up in payment when the interest-only period ends and principal repayment begins.
A Quick Word on Business-Purpose Status
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The business-purpose exemption turns on the loan’s primary purpose, not the property label. Tax treatment varies; consult a qualified professional.
Questions to Ask Before You Apply
- Which rent governs on a leased property: the lease, the 1007, or the lower of the two?
- Is coverage tested on the interest-only payment or a fully amortizing one?
- Which payment sizes the reserves?
- Is the 1007 applied unit by unit on a small multifamily?
- What does the payment look like after the recast?
If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals.
Frequently Asked Questions
Does interest-only always raise my DSCR?
No. It raises the ratio only when the program tests the interest-only payment. Some programs measure coverage on a fully amortizing payment even though you pay interest-only, so cash flow improves while the ratio stays put.
Is Form 1007 a DSCR form?
No. It is an agency appraisal form that DSCR programs borrowed to document market rent. The agencies don’t govern how DSCR lenders use it, so each program sets its own conventions.
If my tenant pays above market, do I qualify on the lease?
Usually not. Most programs credit the lower of the lease and the 1007 market rent, so an above-market lease is capped at the appraiser’s figure. A minority of programs use the higher number, so ask early.
Does a DSCR above 1.00 mean the property cash flows?
No. The ratio compares rent to PITIA only. Vacancy, repairs, management, utilities, and capital expenses sit outside it, so a property can clear the ratio and still run negative in a slow month.
Can I qualify below 1.00 coverage?
A sub-1.00 path is available through select lenders in the network, with leverage and terms adjusted. It is a separate path from programs that start at 1.00, and eligibility depends on credit, reserves, and property review.
