DSCR Loans Explained: How the Ratio Is Calculated and What Lenders Want

DSCR stands for debt service coverage ratio, and the entire loan program rests on one line of arithmetic:

DSCR = gross monthly rent ÷ PITIA

PITIA is principal, interest, taxes, insurance, and association dues. That last A is the one that ambushes condo and townhome buyers, and we will come back to it.

That is the whole formula. No income calculation, no tax returns, no Form 1084 cash flow analysis on your consulting company. The property either covers its own payment or it does not, and the ratio tells the underwriter which.

How to Calculate Your DSCR

Step 1: Build the PITIA

Add four things. Principal and interest from your quoted loan amount and term. Annual property taxes divided by twelve — and use the new assessed number, not the seller's last bill. Annual hazard insurance divided by twelve, quoted as a landlord policy, not an owner-occupied one. Monthly HOA or condo association dues.

Step 2: Establish the gross monthly rent

Gross, not net. Do not subtract vacancy, management fees, or maintenance. The lender is not running your pro forma.

Step 3: Divide

Rent divided by PITIA. Two decimal places. That number is the file.

Three Properties, Three Outcomes

	Property A	Property B	Property C
Gross monthly rent	$3,240	$2,600	$1,700
Principal & interest	$1,690	$1,780	$1,420
Taxes	$480	$560	$390
Insurance	$110	$130	$95
HOA dues	$120	$130	$95
PITIA	$2,400	$2,600	$2,000
DSCR	1.35	1.00	0.85

Property A at 1.35. $3,240 ÷ $2,400. The rent covers the payment with 35% to spare. This is the file that prices best, clears underwriting fastest, and gives you room if taxes reassess upward next January.

Property B at 1.00. $2,600 ÷ $2,600. Exactly breakeven. Most programs set their floor here, so this qualifies — and it qualifies with zero cushion. One insurance renewal, one HOA special assessment, one tax reassessment and the file would not have closed a month later. Underwriters are not sentimental about 1.00, but they will take it.

Property C at 0.85. $1,700 ÷ $2,000. The rent covers 85% of the payment and you fund the other $300 a month — $3,600 a year — out of your own pocket. Some investors will still lend here with compensating factors: a higher credit score, a larger down payment, deeper reserves. Others will decline it outright. Sub-1.0 is a program feature, not a default.

Where the Rent Number Comes From

Three sources, and they do not always agree.

The appraiser's Form 1007. On a purchase of a single-unit rental, the appraiser completes a Single-Family Comparable Rent Schedule alongside the appraisal. The appraiser pulls rental comparables the same way they pull sales comparables and states a market rent opinion. On a vacant property with no lease, this is usually the number.

An executed lease. If a tenant is already in place, the signed lease is real evidence of what the unit produces.

Market rent. Where a lease has expired, a unit is between tenants, or the lease is not arm's length.

When the lease and the 1007 disagree, expect the underwriter to use the lower of the two. That surprises sellers who hand you a lease signed at above-market rent to make the deal look better. It also protects you from buying an inflated number.

It cuts the other way too. If your cousin rents from you at $1,400 on a unit the appraiser calls at $1,900, the below-market lease is the number the file uses. A lease between related parties gets read carefully.

What Lenders Typically Want

These are typical program parameters from a lender's published terms. Treat them as typical, not universal — DSCR is not an agency product, so every investor writes its own box.

Parameter	Typical
Minimum DSCR	Around 1.00; sub-1.0 available with compensating factors
Down payment	20-25%, as low as 15% with 740+ FICO on select programs
Minimum FICO	Around 620; 740+ gets the best pricing
Reserves	Several months of PITIA
Minimum loan amount	Around $100,000
Vesting	Individual or LLC
Income documentation	None

Two of those deserve a note. The $100,000 minimum loan amount quietly removes a lot of Midwest and small-market inventory from DSCR financing — a $90,000 duplex with a beautiful 1.60 ratio may simply be too small a loan to place. And the FICO spread between 620 and 740 is not cosmetic. It moves your down payment, your pricing, and sometimes whether sub-1.0 is available at all.

What Actually Moves Your DSCR

You cannot negotiate the tenant into paying more. You can move PITIA, and every component is reachable.

A larger down payment. Principal and interest scale linearly with the loan amount at a fixed rate. Take Property C: at 25% down the loan is $240,000 and P&I is $1,420. Push to 35% down and the loan drops to $208,000 — 13.3% less principal, so P&I falls 13.3% to about $1,231. PITIA becomes $1,811, and the DSCR moves from 0.85 to 0.94. Still under 1.00, but a different conversation with an underwriter.

The T. This is the component investors chronically underestimate, especially in Texas. The Texas Comptroller's residence homestead exemption removes $140,000 of value from school district taxes — but only on your principal residence. A rental gets none of it. A seller who lived in that Katy house was taxed on a value $140,000 lower than you will be for school taxes. Take the seller's last tax bill as your escrow estimate and your DSCR will be wrong before you close. Pull the current rate from the county appraisal district and run it on the full assessed value.

The I. A landlord policy with proper coverage costs what it costs, but quoting three carriers is free.

The A. HOA dues are inside PITIA. Not beside it, not excluded from it. A $180 monthly HOA on a $2,400 payment is 7.5% of the ratio's denominator. Condo buyers get blindsided by this constantly: they run the numbers on principal, interest, taxes and insurance, get 1.09, and find out at underwriting that with dues the property is at 1.01. Special assessments and dues increases hit the ratio the same way.

Do not "fix" a weak ratio by having the seller sign a lease at a number the market does not support. The 1007 will contradict it, the underwriter will use the lower number, and you will have spent two weeks proving you were willing to try.

Who This Product Is For

DSCR exists because a lot of capable investors cannot document income the way an agency file requires. The gas station owner whose Schedule C shows $48,000 after every legitimate deduction. The IT consultant on corp-to-corp with an S corp and two years of messy K-1s. The borrower who already has four financed properties and does not want a fifth personal DTI calculation.

If your documentation is clean and your DTI has room, a conventional investment loan is usually cheaper — the full comparison runs through vesting, prepayment penalties and the financed-property count. If you are wondering how a lender is legally allowed to skip your income entirely, there is a specific regulation behind it. If you want the property in an entity, that is the other reason people land here.

Run your own ratio before you call anyone. Rent over PITIA, two decimals. You will know more about your deal in four minutes than most people learn in four phone calls.

Frequently Asked Questions

Q: How do you calculate DSCR on a rental property?
A: Divide gross monthly rent by PITIA — principal, interest, taxes, insurance and HOA dues. A $2,600 rent against a $2,600 PITIA is a 1.00 DSCR. Use gross rent, not rent after vacancy or management fees, and use the new tax assessment rather than the seller's old bill, which is often lower because of a homestead exemption you will not get.

Q: What is a good DSCR for a loan?
A: Most programs set the floor around 1.00, meaning the rent exactly covers the payment. Anything at 1.20 or above is comfortable and generally prices better. Below 1.00 the property does not carry itself and you fund the gap monthly; some investors allow it with a higher credit score, larger down payment, or deeper reserves, and others decline it.

Q: Does DSCR include HOA fees?
A: Yes. The A in PITIA is association dues, and they sit in the denominator with everything else. This catches condo and townhome buyers who calculate the ratio on principal, interest, taxes and insurance only and then find their 1.09 is really a 1.01. Special assessments and dues increases move the ratio the same way.

Q: Where does the lender get the rent number?
A: From the appraiser's Form 1007 Single-Family Comparable Rent Schedule, an executed lease, or a market rent opinion. When a lease and the 1007 disagree, expect the underwriter to use the lower figure. That works against a seller's above-market lease and also against a below-market lease with a related tenant.

Q: What credit score do I need for a DSCR loan?
A: Typical minimums sit around 620, with 740 and above earning the best pricing and, on select programs, down payments as low as 15%. Parameters vary by investor because DSCR is not an agency product. Reserves of several months of PITIA and a loan amount above roughly $100,000 are the other common gates.
