The Quick Read: A conventional lender counts only part of a rental’s gross rent, then subtracts the property’s full monthly obligation, and the result lands in your personal debt-to-income math. A DSCR loan skips that route and compares rent to the property’s payment.
A conventional underwriter generally credits 75% of documented gross rent, then subtracts the full PITIA (principal, interest, taxes, insurance, association dues). A positive result adds to your income. A negative result is treated as a debt. DSCR divides rent by PITIA, so the same property can clear DSCR comfortably and still show a loss in conventional math.
- Conventional credits roughly 75% of rent but counts 100% of the payment.
- A negative net result is added to your monthly debts, not ignored.
- DSCR divides rent by PITIA and does not use personal debt-to-income.
- Clearing 1.00 on DSCR is not the same as positive cash flow.
- Whether a property is “DSCR-financed” does not change the conventional math. The rent and the payment still drive it.

Two Different Questions
The two loan types ask different things. Conventional asks whether you can afford the debt. DSCR asks whether the property can carry itself, a framing BiggerPockets draws between the two approaches.
| Factor | Conventional | DSCR |
|---|---|---|
| What qualifies | The borrower | The property |
| Rent treatment | Partial credit, then net against PITIA | Gross rent divided by PITIA |
| Personal income | Central to the file | Not the main driver |
| Negative result | Added to your debts | Shows as a ratio below 1.00 |
Across Lendmire’s wholesale network, DSCR files qualify primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide covers the full program picture.
How Does a Conventional Lender Turn Rent Into Counted Income?
The conventional method is a short sequence. For contrast only, the Fannie Mae Selling Guide shows how the agency route works on a purchase. It does not describe how DSCR loans work.
1. Pick the rent figure. On a purchase, the lender uses an appraiser’s rent schedule. That is Form 1007 for a single-family home or Form 1025 for two to four units. If a lease transfers with the property, the lease must be supported by that market rent.
2. Apply the 75% factor. Monthly gross rent is multiplied by 75%. Practitioners read that cut as an allowance for vacancy and upkeep.
3. Subtract the full PITIA. The result is the adjusted net rental income.
4. Route the result. If it is positive, the lender adds it to monthly income. If it is negative, the lender adds the loss to monthly obligations. The selling guide’s rental income topic says the PITIA is already inside the net figure, so it is not counted twice.
5. Test the total. Your personal debt-to-income ratio then has to fit the lender’s limit.
Fannie Mae reorganized this chapter in a 2026 announcement, so section numbers in older material may not match the current text.
A Worked Comparison
Use ratios rather than dollars. Say a rental’s gross rent sits comfortably above its PITIA, with DSCR at roughly 1.25x. That clears the 1.00 level where many select DSCR programs start.
Now run the conventional math. Rent is cut to 75%. At a 1.25x ratio, 75% of rent equals about 0.94x of PITIA. After subtracting the full payment, the net is slightly negative, around 0.06x of PITIA below zero. That small loss is added to your monthly debts.
Same property. Two answers. DSCR sees a property that covers its payment. Conventional sees a small drag on your income.
The break-even is simple. At 75% credit, a rental has to run above roughly 1.33x coverage before conventional math turns positive. Many rentals sit below that line, which is why they show as a debt in a conventional file.
Which Documents Set the Rent Figure?
The answer depends on the property’s history.
| Situation | Typical conventional rent source |
|---|---|
| Purchase with a transferring lease | Executed lease plus Form 1007 or 1025 |
| Purchase, no lease | Appraiser’s market rent schedule |
| Seasoned rental | Tax return rental schedule, with add-backs |
| Recently acquired or just placed in service | Lease, in limited situations |
On a seasoned rental, the lender starts from the Schedule E figures, adds back items such as association dues, and prorates by months in service. Tax-return rent can understate real cash flow when depreciation and deductions are heavy. That is one reason self-employed and heavy-deduction filers often find DSCR cleaner.
On the DSCR side, files typically lean on the appraiser’s rent schedule and any lease. The exact treatment is lender-specific, so the network’s guidelines, not a conventional rule, set it.
Where the General Rule Breaks
A few edge cases change the picture.
- Positive results have limits. For a departing residence, the guide says a positive net may offset only that residence’s own PITIA. It does not simply add to income.
- Short-term rentals. The old rule of thumb that agencies cannot count short-term rental income is outdated. A newer short-term rental topic allows it under specific documentation rules. On the DSCR side, short-term rental files are a separate path. Purchases reach up to 75% LTV and cash-out up to 70% LTV, expect a 640+ score and about 12 months of hosting history, and a 1.00 coverage floor applies to purchases and refinances alike on the network’s programs, subject to lender guidelines. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Timing varies by file and lender.
- Accessory dwelling units. Income from an ADU on the subject property is capped at 30% of total qualifying income.
- Multi-property portfolios. Each non-subject property is calculated separately, then aggregated. Several small losses stack up.
- Rent reporting. Lenders report gross monthly rent on investment properties even when the rent is not used to qualify.
Why DSCR Wins for Some Investors (and Doesn’t for Others)
The conventional route qualifies the person. A property that cash-flows can still fail if your debt-to-income is stretched.
DSCR fits the investor whose personal file hides the property’s strength. That includes self-employed borrowers, LLC-held portfolios (subject to lender program eligibility), and investors whose tax returns show heavy deductions.
Conventional may be the better call when your income is strong, your debt load is light, and you are financing only one or two properties. It tends to be the lower-cost option. DSCR trades some pricing for flexibility. If your debt-to-income has room and your documents are clean, that trade may not be worth making.
The flip point is portfolio size and income shape. Once new rentals keep adding small negative nets to your debts, or your returns can’t show the real income, DSCR often becomes the practical lane.
What Does DSCR Actually Measure?
DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation. Clearing 1.00 is therefore not the same as positive cash flow, and a thin ratio leaves little cushion once those costs arrive.
Most programs Lendmire places files with start at a 1.00 ratio. Stronger ratios open better pricing and leverage. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
Typical network ranges on a standard long-term rental:
- Purchase: 75%–80% LTV on most files.
- Cash-out refinance: up to 75% LTV, with about 6 months of seasoning common.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest tiers.
- Loans: roughly up to $3,000,000 on standard programs.
- Reserves: commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000.
A larger down payment can lift the ratio, but it never erases credit floors, reserve rules, or property eligibility. Manufactured homes, log homes, and barndominiums are not offered. These are guideline ranges, not commitments to lend.
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
PITIA: the full monthly property obligation: principal, interest, taxes, insurance, and association dues.
Adjusted net rental income: the rent a conventional lender credits after the 75% factor, minus the full PITIA.
DSCR: gross rental income divided by PITIA, a property-level coverage ratio.
Debt-to-income (DTI): your total monthly debts divided by your gross monthly income, the test conventional files must pass.
Form 1007 / Form 1025: appraiser forms that document market rent for a single-family home or a two-to-four-unit property.
Common Misconceptions
- Conventional ignores rent. It does not. It credits part of it.
- The 75% rule is the DSCR calculation. It is not. DSCR divides rent by PITIA with no income test.
- Rent always adds to income. A negative net is counted as a debt.
- A lease alone sets the rent. On a conventional purchase it must be supported by the appraisal, or the lender uses the lesser figure.
- DSCR means no rent proof. DSCR still needs a defensible rent figure.
Practical Next Steps
Compute both numbers before choosing a lane. First, rent divided by PITIA gives your coverage ratio. Second, 75% of rent minus PITIA tells you what a conventional underwriter will see. If the second number is negative and your debt-to-income is already tight, DSCR deserves a serious look. If you finance several properties, that stacking effect matters more.

Frequently Asked Questions
Does a conventional lender count all of a rental’s income?
No. It generally credits about 75% of documented gross rent, then subtracts the full PITIA. The allowance reflects vacancy and upkeep. What remains either adds to income or, if negative, adds to your monthly debts.
Why can a property pass DSCR but hurt my conventional application?
The two tests measure different things. DSCR divides full rent by PITIA, so 1.25x looks healthy. Conventional credits only 75% of rent, so the same property can net negative. Conventional coverage has to run above roughly 1.33x before the net turns positive.
Can short-term rental income count on a conventional loan?
Sometimes. Newer agency guidance allows it under specific documentation rules, so the old “never” rule is outdated. On the DSCR side, network programs expect about 12 months of hosting history and a score around 640 or higher, subject to lender guidelines.
Does a lease alone determine the rent a conventional lender uses?
No. On a purchase the lease must be supported by the appraiser’s rent schedule. If market rent does not support the lease, the lender writes a justification or uses the lesser figure.
Does DSCR coverage mean the property makes money?
No. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the number, so a 1.00 ratio can still leave a property cash-negative.
