How a DSCR loan evaluates rental income
A debt-service coverage ratio (DSCR) loan compares lender-accepted property income with the debt obligation used in the lender’s calculation. Depending on the program, that expense may include principal, interest, property taxes, insurance, and association charges. The precise income and expense definitions vary by lender.
Some DSCR programs may rely substantially on a property’s income rather than the personal-income documentation used for many conventional mortgages. That can be relevant for an investor buying a non-owner-occupied property or a borrower with complex income, but it does not make the rest of the application irrelevant. Lenders may also review credit, assets, reserves, property details, or experience.
Short-term rental income is not treated uniformly. A lender may consider an appraisal or rent analysis, operating history, booking records, or other evidence; some may not accept projected platform income as presented in an investor’s spreadsheet. Investment-property financing can also differ from owner-occupied financing in down payment, reserves, rate, fees, and term. Approval and documentation requirements depend on the borrower, property, lender, and program. Before comparing options, find out what income method the lender uses and which expenses count.

Miami rental context, not a property income forecast
Zillow Research reported Miami rent of $2,965 in September 2026. That is broad rental-market context—not a nightly rate, booking forecast, or income figure a DSCR lender will necessarily accept.
Verify the rental case for the exact Miami property
Miami’s general rental figures cannot establish whether a particular short-term rental is permitted or what it can earn. Requirements may depend on the property’s jurisdiction, zoning, building rules, and association documents. Verify the applicable rules for the address, then build the income case from evidence tied to that property and confirm what the lender will use.
The Census ACS 5-Year, 2023 reported a Miami-Dade County rental vacancy rate of 5.36%. This is a broad rental-market measure, not a forecast of short-term bookings or vacancy at an individual property. Treat it as context, not as a substitute for documented operating history or a lender-accepted income analysis. I check early which lenders may consider a property’s short-term rental income and what evidence each needs, so we can identify documentation gaps before they become a contract-timing problem.

Just focus on that rental income, and I’ll handle everything else for you.
Use Miami values as context, not a deal valuation
Zillow Research reported a Miami home value of $583,705 in September 2026. That citywide measure can frame the scale of the market, but it does not establish a particular property’s purchase price, appraisal, financing need, or rental income. For a DSCR analysis, the property’s actual price and documented, lender-accepted income matter more than a broad value average.
For additional context, the Census ACS 5-Year, 2023 reported a Miami-Dade County median home value of $425,400. That county figure and the citywide Zillow measure describe different geographies and sources; neither should be treated as a valuation for a specific short-term rental.
Allow time to resolve property and documentation questions
Zillow Research reported 56 days to pending in Miami in September 2026. That market timing is a reason to investigate permitted use, income evidence, and association or building documents early rather than assuming they can be resolved at the last minute. The figure does not predict the timeline for a particular purchase or loan approval.
Zillow Research also reported that 16.07% of Miami listings had price cuts in September 2026. For an investor, that is market context—not evidence that a given property is mispriced or that its projected rental income is sound. Evaluate the property and financing assumptions on their own merits.
Can I get a DSCR loan if the property barely breaks even?
Possibly, but it depends on the lender’s DSCR calculation, including the income and expenses it accepts; a spreadsheet showing break-even does not establish the underwriting result. In Miami, Zillow Research reported rent of $2,965 in September 2026, while the Census ACS 5-Year, 2023 reported a Miami-Dade County rental vacancy rate of 5.36%. Those broad figures do not establish the subject property’s income or expenses. Confirm the lender’s method and test the deal using property-specific evidence and the full costs it counts.
What DSCR ratio do lenders require?
There is no single ratio established here: requirements and calculation methods vary by lender and program. For a Miami short-term rental, do not infer a qualifying ratio from general market rent or vacancy data. Zillow Research reported Miami rent of $2,965 in September 2026, but that broad figure is not the income a lender necessarily accepts for your property. Ask the lender which income evidence and debt expenses it will use, then calculate the ratio on that basis.
