Thinking about purchasing a 30A vacation rental but unsure how to finance it without leaning on your W‑2 income? You are not alone. Many investors use DSCR loans to qualify based on a property’s cash flow rather than personal income. In this guide, you will learn how DSCR lending works, how lenders evaluate short‑term rental income on 30A, and what to verify in Walton County before you write an offer. Let’s dive in.
Debt Service Coverage Ratio, or DSCR, tells a lender if a property’s income can cover its mortgage. The formula is simple: DSCR = Net Operating Income (NOI) divided by Annual Debt Service. If a property produces $50,000 in NOI and the annual mortgage payments total $40,000, the DSCR is 1.25.
Most DSCR lenders target a minimum DSCR between about 1.0 and 1.25, depending on loan size, loan‑to‑value, and risk. Lower DSCRs may be possible with higher rates or extra reserves. These loans are designed for investors and are typically underwritten on the property’s numbers rather than your personal debt‑to‑income ratio.
Common DSCR loan features include higher rates than conforming loans, interest‑only options, 5 to 30‑year terms, and LTV caps that often fall between 70 and 80 percent for single‑family short‑term rentals. Policies vary by lender, so get clear on their thresholds early.
Walton County’s 30A corridor is a high‑demand coastal market with strong seasonality. Spring and summer book fast at premium rates. Fall and winter can be softer. Lenders and investors both expect these swings, so they focus on how the full year shakes out.
Because DSCR loans center on property cash flow, proven short‑term rental performance or credible market projections can help you qualify even when personal income documentation is complex. This can be a good fit if you are self‑employed, retired, or scaling a portfolio.
Just remember that 30A’s premium pricing often comes with higher operating costs. Insurance, HOA fees, and maintenance can be materially higher along the coast. Model these conservatively so your DSCR still works after real‑world expenses.
If the home or condo has a rental track record, lenders often favor trailing 12‑month revenue. Platform statements, management P&Ls, 1099s, or bank deposits can all help document gross receipts. Strong history can carry real weight in underwriting.
No history yet? Many DSCR lenders accept third‑party reports or local rent comps. Credible sources include short‑term rental analytics providers and local vacation rental managers. Lenders may haircut projections to stay conservative.
Lenders typically start with gross rental revenue, then deduct operating expenses to reach NOI. Expect to include management fees, cleaning, utilities, HOA or condo dues, property taxes, insurance for wind and flood where applicable, routine maintenance, platform and marketing fees, a vacancy allowance, and a capital reserve.
Coastal seasonality makes conservative modeling essential. Many underwriters stress occupancy by 10 to 30 percent, include a 10 to 20 percent vacancy allowance, and set a 5 to 10 percent capital reserve. The goal is a DSCR that holds up even when shoulder seasons are slower.
30A demand peaks in spring and summer, then eases in the off‑season. Plan for uneven monthly cash flow. Your pro forma should show how you bridge quieter months, especially if using an interest‑only period.
Hurricane and flood risk is part of coastal ownership. Lenders will require adequate hazard coverage and flood insurance in Special Flood Hazard Areas. Premiums and wind mitigation costs can shift each year, so get updated quotes before you finalize offers.
Many 30A communities and buildings have specific short‑term rental policies. Minimum night rules, caps on rental frequency, and prohibitions are not uncommon. Confirm HOA and condo documents early to ensure the rental plan you envision is allowed.
Short‑term rentals in Walton County require compliance with local registration and taxes, including tourism bed taxes and sales tax collection and remittance. Add any permitting, inspection, and compliance costs into your operating budget and calendar.

Use this illustrative example to see how DSCR math comes together. Imagine a 30A cottage with projected gross rental revenue of $120,000. You apply conservative allowances consistent with coastal STR underwriting:
That totals $80,000 in modeled expenses, leaving $40,000 NOI. If annual debt service on your loan is $32,000, DSCR = $40,000 ÷ $32,000 = 1.25. If your lender requires 1.25, you are right at the threshold. If rates rise or insurance renews higher, DSCR could dip. This is why stress tests matter.
