FINANCING COMPARISON · INTERACTIVE SCENARIO

DSCR loan vs conventional loan

Put the same rental under two financing lenses. See the property coverage a DSCR lender may examine beside a simplified borrower DTI for conventional financing.

Use this to pressure-test a scenario. It is not an approval, eligibility decision, rate quote or substitute for a lender’s underwriting.

YOUR ASSUMPTIONS

Compare one deal, two loans

Property and borrower

“Other monthly debts” can include recurring obligations such as auto, student-loan and card payments. This simplified DTI does not apply rental-income credits or every underwriting adjustment.

What this model includes

PITIA here means principal, interest, property taxes, insurance and HOA dues. Add any required flood insurance or subordinate financing to the entered insurance or debt amounts. Mortgage insurance and other costs are outside the model.

Read the outputs as two different stress tests

A DSCR ratio measures the property side of the deal. In this calculator, a $3,000 rent and $2,400 PITIA produce 1.25× coverage. The extra 0.25 does not mean a 25% profit margin: vacancy, repairs, management, utilities, capital expenditures and other operating costs are outside this residential gross-rent calculation.

The conventional DTI shown here measures a narrower borrower scenario. It adds the proposed conventional PITIA to the other monthly debts you enter, then divides by gross monthly income. Real underwriting can treat rental income or loss differently, count additional liabilities, test reserves and apply automated-underwriting findings. That is why the conventional card says “planning output” rather than pass or fail.

Why the conventional rent treatment is not baked into the DTI

Applying all rent as ordinary income would overstate the result. Fannie Mae’s current subject-property rental-income guidance describes documentation rules and, for applicable purchases, a 75% gross-rent step followed by subtraction of PITIA to determine adjusted net rental income. It also changes treatment based on factors such as rental-property management experience. A lender must apply the version and facts relevant to the file.

Because this page does not collect that full underwriting record, it leaves rent out of the conventional DTI. The visible rent still drives the DSCR scenario, while the conventional result provides a clean “before rental treatment” baseline.

Down payment is only one part of cash required

“Cash down” equals purchase price multiplied by the entered down-payment percentage. It excludes closing costs, discount points, lender fees, prepaid taxes and insurance, reserves, repairs and appraisal gaps. Loan-to-value limits also depend on the transaction and property. Freddie Mac’s current maximum-ratio table, for example, distinguishes one-unit from two- to four-unit investment-property purchases, and its investment-property overview points lenders to additional eligibility and reserve requirements.

DSCR = gross monthly rent ÷ monthly PITIA   ·   Simplified DTI = (conventional PITIA + other monthly debts) ÷ gross monthly income

How to make the comparison useful

  1. Use the rate, points and amortization offered for each actual loan option; do not assume the same pricing.
  2. Enter taxes from the likely post-sale assessment, the full insurance estimate and mandatory association dues.
  3. Use the rent a lender is likely to document, then test a lower figure to see how quickly DSCR loses its cushion.
  4. Compare the cash requirement and contract terms after the payment math. A lower payment can still come with larger fees or stricter prepayment terms.
Where the scenario stops

These estimates do not verify credit, appraisal, rent eligibility, reserves, loan limits, property eligibility, mortgage insurance, lender overlays or every liability used in underwriting. Only a lender can determine approval and final terms.

Common questions

What is the main difference between a DSCR loan and a conventional loan?

A DSCR loan generally focuses on the rental property’s income relative to its housing payment. Conventional underwriting evaluates the borrower, the property, income, assets, liabilities and agency or lender rules.

Does a DSCR loan use debt-to-income ratio?

Many DSCR programs qualify primarily from property cash flow rather than a personal DTI calculation, but program rules vary. A lender can still review credit, liquidity, reserves, property eligibility and other risks.

Can rent help qualify for a conventional investment-property loan?

It can, subject to documentation, experience and underwriting rules. This calculator intentionally shows a simple DTI before rental-income treatment so it does not imply that all entered rent will be accepted.

Is the lower monthly payment always the better loan?

No. Compare rate, points, fees, prepayment terms, recourse, documentation, reserves and total cash required as well as the payment. The calculator does not estimate those items.
