What is a DSCR loan?
A DSCR loan is an investment property loan where the lender qualifies the deal mainly on the property’s rental income compared with its debt payments. Instead of tax returns and W-2s, the lender looks at the rent, the payment, and the borrower’s credit and cash reserves.
The term gets used two ways. In the one-to-four unit world, “DSCR loan” usually means a non-QM business-purpose loan for rental homes and small multifamily. In commercial lending, almost every apartment loan on five or more units is sized on DSCR, so nobody bothers with the label. That’s just how the market works.
How to calculate DSCR
DSCR is the property’s income divided by its debt service for the same period. A ratio of 1.00 means income exactly covers the payment, and 1.25 means income is 25% more than the payment. Lenders define the income side differently by loan type, so ask which version yours uses.
- Commercial and agency loans: DSCR = net operating income (NOI) ÷ annual principal and interest.
- NOI = effective gross income minus operating expenses such as taxes, insurance, utilities, repairs, payroll and management, before debt service and depreciation.
- Many 1–4 unit DSCR lenders: DSCR = monthly gross rent ÷ monthly PITIA (principal, interest, taxes, insurance and any HOA dues).
- Lenders usually use the lower of actual leases or market rent and add their own vacancy and expense assumptions.
- To find the largest loan a DSCR test allows: maximum annual debt service = NOI ÷ required DSCR, then convert that payment to a loan amount at the quoted rate and amortization.
Non-QM DSCR loans for 1–4 unit rentals
Non-QM DSCR loans are business-purpose mortgages on one-to-four unit investment properties that don’t follow the qualified mortgage rules. Truth in Lending Act rules under Regulation Z exempt credit extended primarily for a business or commercial purpose, and credit extended to a non-natural person such as an LLC (12 CFR 1026.3(a)). That’s why these lenders can skip the ability-to-repay income documentation that applies to a consumer home loan.
Each lender sets its own minimum DSCR, credit score, loan-to-value and reserve rules, and pricing usually gets better as the ratio rises. Many lend to an LLC with a personal guaranty. Ask whether the loan has a prepayment penalty, and confirm whether the rate is fixed for the full term.
Agency and commercial multifamily loans sized on DSCR
Loans on five or more units are sized on both DSCR and loan-to-value, and the lower of the two results sets the loan. Fannie Mae’s fixed-rate term sheet lists a minimum DSCR of 1.25x and a maximum LTV of 80% for conventional properties, with non-recourse execution available on most loans over $750,000. Freddie Mac’s conventional forward commitment term sheet uses the same 1.25x and 80% figures.
HUD is more generous on coverage. Mortgagee Letter 2025-03 lowered the minimum debt service coverage for market-rate Section 223(f) refinance or acquisition loans to 1.15 and raised the maximum loan-to-value to 87%. CMBS, life company and bank loans set their own tests, and they change with the market.
| Loan | Property | Qualifies on | Published DSCR / LTV |
|---|---|---|---|
| Non-QM DSCR loan | 1–4 units | Rent ÷ PITIA, credit, reserves | Set by each lender |
| Fannie Mae conventional fixed-rate | 5+ units | NOI ÷ debt service and LTV | 1.25x min / 80% max |
| Freddie Mac conventional | 5+ units | NOI ÷ debt service and LTV | 1.25x min / 80% max |
| HUD 223(f), market rate | 5+ units | NOI ÷ debt service and LTV | 1.15 min / 87% max |
| CMBS, bank, life company | 5+ units | NOI ÷ debt service, LTV, debt yield | Set by each lender |
Worked example: a fourplex DSCR loan
A fourplex rents for $10,000 a month. The investor wants a $900,000 loan at 7.0% on a 30-year schedule. Principal and interest are $5,987.72 a month. Add $1,000 a month for property taxes and $400 for insurance, and PITIA is $7,387.72.
Using the rent-to-PITIA method, DSCR is $10,000 ÷ $7,387.72 = 1.35. If the lender wants a higher ratio for the best pricing, cutting the loan to $800,000 lowers principal and interest to $5,322.42 and PITIA to $6,722.42, lifting DSCR to 1.49.
Worked example: a 5+ unit apartment building
An apartment building has NOI of $600,000. At a 5.5% cap rate it’s worth about $10,909,091, so 80% LTV would allow about $8,727,273. Now apply the DSCR test at 1.25x with a 6.0% rate and 30-year amortization.
Maximum annual debt service is $600,000 ÷ 1.25 = $480,000, or $40,000 a month. At 6.0% over 30 years, that payment supports a loan of about $6,671,665. A $7,000,000 loan would cost $503,622 a year and produce a DSCR of only 1.19, so it fails. Here the DSCR test, not LTV, sets the loan, and the buyer needs to bring more equity.
This happens a lot when interest rates are high relative to cap rates. It’s also why sponsors watch NOI growth so closely: every dollar of NOI added through rent increases or lower expenses raises the loan a building can support at refinance.
| Test | Calculation | Result |
|---|---|---|
| Value | $600,000 ÷ 5.5% cap rate | $10,909,091 |
| LTV limit (80%) | $10,909,091 × 80% | $8,727,273 |
| Max debt service at 1.25x | $600,000 ÷ 1.25 | $480,000 a year |
| DSCR loan limit | $40,000 a month at 6.0%, 30 years | $6,671,665 |
| $7,000,000 loan | $600,000 ÷ $503,622 | 1.19x (fails 1.25x) |
What lenders look at besides DSCR
DSCR is the headline, but lenders underwrite the whole borrower and property. Expect questions on each of these:
- Rent roll and leases: actual rents, vacancy, concessions and lease expirations.
- Trailing operating statements, often the last 12 months, to check NOI.
- Credit, net worth and liquidity of the borrower and any guarantor.
- Experience owning and managing similar property, which matters more on larger loans.
- Property condition, deferred maintenance and required repair reserves.
- Loan-to-value from an appraisal, and on commercial loans, debt yield.
DSCR loan pros and cons
DSCR loans let investors grow without personal income limits, but the property has to carry the debt. Self-employed investors and people with several properties often like them, since tax returns with heavy depreciation can make personal income look low.
The trade-offs are real. Non-QM DSCR loans usually price above conventional owner-occupied mortgages, and some carry prepayment penalties that limit an early sale or refinance. When rates rise, the same NOI supports a smaller loan, which can make a refinance or sale harder.
DSCR loan vs conventional investment property mortgage
A conventional investment property mortgage qualifies you on personal income and debt-to-income ratio, while a DSCR loan qualifies the property on its rent. For an investor with a strong W-2 and only a few rentals, a conventional loan is often cheaper. Once personal income stops supporting more loans, or the deal is held in an LLC, a DSCR loan or a commercial loan usually takes over.
On five or more units the choice disappears. Conventional one-to-four unit home loans don’t apply, and every lender sizes the deal on NOI. That’s why apartment buyers learn to think like lenders, starting with the rent roll and trailing expenses.
| Conventional investment loan | DSCR loan (1–4 units) | Multifamily loan (5+ units) | |
|---|---|---|---|
| Qualifies on | Personal income and DTI | Property rent vs PITIA | NOI vs debt service and LTV |
| Borrower | Individual | Individual or LLC | Single-purpose entity |
| Income documents | Tax returns, W-2s | Leases or rent schedule | Rent roll, operating statements |
| Recourse | Full | Often a personal guaranty | Often non-recourse with carve-outs |
How DSCR fits with cap rate, NOI and cash-on-cash return
DSCR measures safety for the lender, while cap rate and cash-on-cash return measure value and yield for the owner. NOI drives all three. Cap rate is NOI divided by value; DSCR is NOI divided by debt service; cash-on-cash return is cash flow after debt service divided by the cash invested.
A deal can show a strong cap rate and still fail DSCR when rates are high. Run all three before you make an offer, and stress-test DSCR at a higher rate if the loan floats or matures soon.
Using DSCR to evaluate a syndication
If you invest passively in apartment syndications, the sponsor’s DSCR tells you how much cushion the building has before it can’t pay its loan. Read the offering documents for the loan’s rate, amortization, interest-only period, maturity and any rate cap, and look at the projected DSCR at the start and after any interest-only period ends.
Also ask how the business plan affects coverage. A value-add plan may start with a thin ratio that improves as renovated units lease up, and that gets riskier if the timeline slips.
