DSCR Loans for Miami Investors: How the Ratio Works

Short answer

A DSCR loan qualifies an investment property on its rental income instead of your personal income: the lender divides the monthly rent by the full monthly payment, including principal, interest, taxes, insurance and HOA dues. A ratio of 1.00 means the rent covers the payment exactly; above 1.00 the property cash flows. DSCR loans are business-purpose loans for non-owner-occupied rentals, not for a home you live in.

What DSCR means and how it is computed

DSCR stands for debt service coverage ratio. For a residential rental, lenders compute it this way:

• DSCR = monthly rent ÷ monthly PITIA
• P and I: principal and interest on the new loan.
• T: property taxes, divided by 12.
• I: homeowners or hazard insurance, plus flood insurance if required, divided by 12.
• A: association dues (HOA or condo fees), monthly.

Rent usually comes from a signed lease or from a market rent survey that the appraiser completes. No W-2s, no tax returns, no personal debt-to-income ratio. Your credit score, down payment, reserves and the property itself still matter a lot.

Every lender sets its own minimum ratio, and some programs accept a ratio below 1.00 with more down payment. That's why we shop the same file across several lenders. For the short definition, see what is DSCR.

A worked example with Miami-style costs

Illustrative numbers only, not a quote. Say you buy a two-bedroom condo in Brickell to rent long-term.

• Market rent from the appraiser: $3,200 a month
• Principal and interest on the loan (example): $1,850
• Property taxes: $450 a month
• Insurance (HO-6 walls-in policy): $100 a month
• HOA dues: $750 a month
• PITIA total: $3,150

DSCR = $3,200 ÷ $3,150 = 1.02. The rent covers the payment with a little room to spare.

Now raise the HOA to $1,050 after a special assessment or a budget increase. PITIA becomes $3,450 and DSCR drops to 0.93. Same rent, same loan, different answer. That is why we ask for the building's current HOA amount and any approved assessments before we run numbers.

Insurance and HOA: the two costs that break Miami deals

In South Florida, taxes and the loan payment are fairly predictable. Insurance and association dues are not, and both sit inside the ratio.

• Single-family and townhomes: you carry the full hazard policy (including windstorm). If the property is in a FEMA special flood hazard area, the lender will require flood insurance, and that premium goes into PITIA too.
• Condos: the association insures the building, and that cost is built into the HOA dues. You carry an HO-6 policy for the interior. Older buildings going through structural repairs can raise dues or levy special assessments.
• Get real quotes early. Ask your insurance agent for a quote during the inspection period, not at the end. Ask the seller or management company for the current budget and any pending assessments.
• Escrow. Many DSCR lenders collect taxes and insurance in an escrow account each month, so the payment you budget for matches the PITIA the lender used.

DSCR is a business-purpose loan

DSCR loans are for investment property you will not live in. They are made as business-purpose loans, which is a different legal category from a home loan.

Regulation Z, the federal Truth in Lending rule, exempts credit extended "primarily for a business, commercial or agricultural purpose" (12 CFR 1026.3(a)). The CFPB's official commentary adds that credit to acquire, improve or maintain rental property that is not owner-occupied is deemed to be for business purposes, regardless of the number of units.

What that means for you:

• You will sign a business-purpose and non-owner-occupancy statement. It must be true. Living in a home financed as an investment loan is occupancy fraud.
• Many investors close in the name of an LLC. Lenders usually ask for the LLC documents from Sunbiz and a personal guarantee.
• Consumer protections tied to owner-occupied home loans, such as the ability-to-repay rule, are generally not the framework for these loans. Read your terms carefully, especially any prepayment penalty.

If you plan to live in the property, even part-time, ask us about a bank statement loan or a conventional loan instead.

Short-term rentals in unincorporated Miami-Dade

Some DSCR lenders will use short-term rental income (Airbnb, Vrbo) instead of a long-term lease. Before you count on it, confirm the property can legally operate as a vacation rental.

According to Miami-Dade County's short-term vacation rental page (retrieved October 2026), these rules apply in unincorporated Miami-Dade, where a short-term rental is one rented for less than 30 days:

• You must obtain a county Certificate of Use before listing the property on any platform. An inspection is scheduled when you apply, and a new CU must be obtained every year.
• The rental must be licensed by the State of Florida and registered with the Florida Department of Revenue, with a tourist tax account for rentals of six months or less, plus a county Local Business Tax Receipt.
• Overnight occupancy is capped at 2 persons per bedroom plus 2 per property, up to 12 persons.
• In Estate or Low Density Residential areas, the responsible party must live at the property more than six months per calendar year.

If the property is inside a city (Miami, Miami Beach, Doral and others), the county says to contact that municipality for its rules. Condo and HOA documents can also ban short-term rentals outright. We check both before a lender counts STR income.

What you need to apply

• The purchase contract or, for a refinance, the current mortgage statement.
• A signed lease, or the property's rental history if it is already rented.
• Proof of down payment and reserves (bank or brokerage statements).
• LLC documents if you are buying in a company name.
• Insurance quote and HOA information.
• Credit authorization. No pay stubs or tax returns are needed for income.
