The Quick Read: The loan amount is the smallest of three limits: what the rent can carry after taxes, insurance, and association dues; the leverage cap on the program; and the credit and loan-size grid. Rent is divided by the target coverage ratio to find the maximum monthly obligation, taxes and insurance come out, and what remains supports principal and interest. Memphis is a useful example because its taxes take a heavy slice of that obligation.
- Rent sets one ceiling and leverage sets another. The lower one controls.
- Taxes and insurance do not shrink when the loan shrinks. Only the principal-and-interest slice responds.
- On a purchase, most files across the network land at 75%-80% LTV, subject to lender guidelines.
- The appraiser’s market-rent opinion, not the investor’s pro forma, usually drives the number.
- Clearing 1.00 is not the same as positive cash flow.
Most investors ask the question backwards. They find a price, apply a down payment, and then wonder whether the rent will cooperate. Lenders run it the other way. This article walks through that reverse math using Memphis as the worked example, then covers the edge cases where the general rule bends.

What Does “Lending on Rental Income” Actually Mean?
A DSCR loan sizes the debt against the property’s rent instead of the borrower’s paycheck. Credit, reserves, and property eligibility still matter.
These 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.
Across our wholesale network, the coverage ratio for 1-4 unit rentals is gross rent divided by PITIA: principal, interest, taxes, insurance, and any association dues. Some commercial textbooks divide net operating income by debt service instead. For the one-to-four-unit investor product, the PITIA version is the typical one, but it is smart to confirm which version a program uses.
For the full picture of how these loans fit together, see the complete DSCR loans guide.
Key Terms Defined
- DSCR: the debt service coverage ratio, meaning the property’s rent used for lender review divided by its monthly PITIA.
- PITIA: principal, interest, taxes, insurance, and association dues, the full monthly carrying cost the rent must cover.
- LTV: loan-to-value, the loan amount divided by the lesser of the purchase price or appraised value.
- Market rent: the rent an appraiser concludes the property would command, usually shown on a rent schedule.
- Form 1007: the Single-Family Comparable Rent Schedule, an appraisal form that DSCR files commonly borrow.
- Form 1025: the Small Residential Income Property Appraisal Report used for 2-4 unit properties.
The Fannie Mae Selling Guide names these two appraisal forms. DSCR loans are not agency products, and agency rules do not govern them. The forms are simply a shared language for documenting rent.
How Does the Lender Turn Rent Into a Loan Size?
The lender back-solves from rent. It takes rent used for lender review, divides by the target coverage ratio, subtracts taxes, insurance, and dues, and converts the remaining payment room into a principal amount. Then the leverage cap is applied and the smaller number wins.
Here is the sequence, step by step:
1. Pick the rent figure. This is the income the lender will credit. More on that below.
2. Set the target coverage. Divide rent by the ratio. At 1.00, the maximum PITIA equals the rent. At a stronger ratio, the maximum PITIA is lower, so the loan is smaller.
3. Subtract the fixed costs. Taxes, insurance, and association dues come out first. They do not scale with the loan.
4. What remains is payment room. That room covers principal and interest only.
5. Convert room to principal. Term and structure matter here. Interest-only periods and 40-year amortizations, available through select lenders in the network, stretch the same payment room into a larger loan.
6. Apply the leverage cap. On a purchase, most files land at 75%-80% LTV. The tighter of the rent-supported amount and the LTV amount controls.
7. Check the grid. Credit tiers and loan size limits sit on top. Standard programs run up to $3,000,000.
The appraisal does double duty. It sets value, which drives LTV, and market rent, which drives coverage. One report can cap you on both fronts.
Minimum coverage of 1.00 is where many select programs start. It is a program floor, not a universal standard. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. A stronger ratio generally opens better leverage and pricing.
Which Rent Does the Lender Count?
- Leased property: the lender generally credits the lower of the signed lease and the appraiser’s market rent. An above-market lease does not lift the ratio.
- Below-market lease: the lease can govern, and the lender may use the lower figure.
- Vacant or freshly rehabbed: everything rests on the rent comps. That opinion is the single point of failure.
- Family-member tenants: below-market rent from relatives draws scrutiny, and market rent usually governs.
- 2-4 units: Form 1025 includes the rent analysis, and each unit is weighed against its own lease or market rent.
For a closer look at how rental income gets counted on the conventional side, see Lendmire’s piece How Much Rental Income a Conventional Lender Counts From DSCR Rentals.
Short-term rentals work differently. Across the network, STR purchases run up to 75% LTV, refinances around 70%, and cash-out 70% on short-term-rental collateral. Expect a 640+ score and about 12 months of hosting history on refinances. Income comes from platform payout history or a third-party projection rather than a rent schedule. Both purchases and refinances carry a 1.00 coverage floor. 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. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Why Memphis Shrinks the Loan Faster Than the Price Suggests
Memphis rents look strong against prices, but property taxes take a large slice of PITIA. Because taxes do not fall as the loan falls, a lower-priced house with a heavy tax bill supports less debt than its rent-to-price ratio implies.
Tennessee assesses residential property at 25% and commercial or industrial property at 40%, according to The 901 Report. That report also notes that the county and the city set separate rates, that the county’s fiscal 2027 rate is $2.70 per $100 of assessed value, and that Shelby County reappraises on a four-year cycle, with the latest taking effect in 2025. A tax-appeal resource, AppealDesk, describes Shelby County’s effective rate as the highest in Tennessee.
Two practical consequences follow:
- Classification matters. Taxes sit in PITIA, so whether a rental is treated as residential or commercial changes the denominator. Confirm the classification with the Shelby County Assessor before you model the deal.
- Timing matters. A reappraisal or rate change can move PITIA after the file is underwritten. Build in a cushion.
Memphis Rent Signals: Context, Not Underwriting Inputs
Memphis rent data is mixed, and none of it replaces the appraiser’s rent opinion. SFR Analytics puts the metro median asking rent at $1,525, while a local property manager’s quarterly update reported 39.5% of listings offering concessions.
That gap is the point. Appraisers pull comps from current listings and signed leases, and concessions or asking-rent cuts can pull the rent schedule below what an investor expected. A listing tracker reported 1,214 asking-rent cuts against 142 raises in a 30-day window, though it is vendor data best read qualitatively.
If the appraised rent lands below your pro forma, the rent-supported loan shrinks and you bring more cash to the table. Price deals off conservative rent, not asking rent.
What Moves the Number?
Seven inputs move the supportable loan. Each one pushes in a predictable direction.
| Lever | Effect on supportable loan |
|---|---|
| Higher appraised rent | Raises it |
| Lower target coverage ratio | Raises it |
| Lower taxes | Raises it |
| Lower insurance cost | Raises it |
| HOA or association dues | Lowers it |
| Interest-only or 40-year term | Raises it (select lenders) |
| Lower LTV cap | Caps it regardless of rent |
A larger down payment lowers the payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Three Illustrative Memphis Tiers
These are modeled illustrations of direction, not quotes or market data. Each describes how the same logic behaves at different price points.
| Tier | Rent vs. price | Tax weight | What usually controls |
|---|---|---|---|
| Low-priced starter house | Strong ratio | Heavy relative to price | Rent coverage, and sometimes loan-size limits |
| Mid-priced single-family | Moderate ratio | Moderate | Whichever of LTV or coverage is tighter |
| Higher-priced renovated house | Weaker ratio | Lighter relative to price | LTV, then coverage if rent softens |
Small balances deserve a note. Standard programs run up to $3,000,000, and balances below the standard-program minimum route through select lenders in the network, so a very cheap Memphis house is not always a standard-program fit.
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.
When the Rent Falls Short
When rent will not carry the loan you want, the fix is usually one of five moves:
- Raise the documented rent, if the market supports it.
- Lower the price.
- Add down payment to reduce the payment and lift coverage.
- Change the structure, such as interest-only or a longer term through a select lender.
- Look at sub-1.00 paths. These are available through select lenders in the network, with leverage and terms adjusted.
Think carefully about the last one. A sub-1.00 structure is defensible if the property has a real appreciation story or a clear rent-growth plan. If you reach for it because the numbers fail at every address you tour, that signals a problem with the submarket selection, not the loan.
No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence.
Rent Coverage Is Not Cash Flow
A coverage ratio above 1.00 means rent covers PITIA. It does not mean you keep money. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation entirely.
This matters in Memphis, where concessions and softer rents can erode real income even while the lender’s math still clears. Treat the ratio as a lender test and run your own operating budget separately. Many investors look for a cushion above the program floor for exactly this reason.
What the Lender Still Checks
Rental coverage is one test among several. Across our wholesale network:
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Leverage: purchases typically run 75%-80% LTV. Cash-out refinances top out around 75% LTV, with about 6 months of seasoning as the common expectation. Rate-and-term refinances can reach higher on select programs.
- Reserves: commonly around 6 months of PITIA, stepping up to about 9 months above $1,500,000. Conservative files at modest leverage can see reserves waived.
- Property type: manufactured homes, log homes, and barndominiums are not offered.
- Ownership: LLC ownership is common, subject to program terms. These loans are generally full recourse to the LLC’s members through personal guarantees, so credit still matters.
Programs change and every file is underwritten individually.
Purchase Versus Refinance
On a purchase, the appraisal and rent schedule set both limits at once. On a refinance, the same math applies, with leverage capped lower on cash-out. The cash-out question depends on what you do with the proceeds: pulling equity into another deal where coverage still works is straightforward, while pulling it into a market where the math does not pencil deserves a stress test first.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Is the loan amount just LTV times price?
No. The rent-supported amount can be lower than the LTV amount, and the lower one controls. A property priced attractively against its rent can still support less debt than the LTV cap allows once taxes and insurance are subtracted.
Does my lease set the income figure?
Not on its own. The lender generally credits the lower of the signed lease and the appraiser’s market rent, so an above-market lease does not lift the ratio. On a vacant purchase, the appraiser’s market-rent opinion is the only figure available.
Do I need to show personal income?
The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, reserves, and property eligibility still apply, and these loans are generally full recourse to the members of an owning LLC.
Can a Memphis rental with a heavy tax bill still work?
Yes, if rent is strong enough to carry the full obligation. Taxes sit in the denominator and do not shrink with the loan, so higher taxes reduce the supportable loan. Confirm the property’s tax classification with the assessor before modeling.
Does clearing 1.00 mean the property cash flows?
No. The ratio compares rent to PITIA only. Vacancy, repairs, management, utilities, and capital expenses are outside it, so run a separate operating budget.
