Short-Term Rental Loans in South Carolina: Financing the Airbnb, Honestly
Program and regulatory figures verified July 24, 2026. Details change; confirm your scenario with us.
The lending question on a South Carolina short-term rental is simple: can the revenue be documented, is the operation legal where it sits, and does the coastal insurance pencil? Get those three right and the DSCR structure does the rest.
How short-term rental income is counted
Three lanes, in order of underwriting strength:
- Operating property, 12+ months of history: trailing Airbnb/VRBO statements support the ratio directly. The cleanest file, and the reason an established, permitted STR is worth a premium at purchase.
- No history, long-term-rent fallback: the appraiser's Form 1007 market rent qualifies the loan as if it were a long-term rental. If the deal pencils on that rent, the STR upside is margin, not a lending assumption. This is the structure we recommend most often, especially in a cooling market like Myrtle Beach.
- No history, STR projection: some programs accept a market-data projection with a haircut, commonly 20–25% off (a few use 70–80% of projected revenue). More down and more reserves usually ride along.
Program specifics vary, and this is where a direct lender who writes these weekly earns the fee: we tell you which lane your property fits before you're under contract. Ratio mechanics: the DSCR guide.
Permit first, loan second
South Carolina's coast went several directions at once, and the underwriting has to respect that. Folly Beach sits at its 800-permit cap, Mount Pleasant is closed to new applicants, Charleston regulates by zone and category, Isle of Palms has no cap, and Hilton Head now bars corporate-entity permit holders. On any deal where the permit path is uncertain, we structure the loan to pencil on long-term rent so the purchase survives a council vote or a review outcome. That conservatism costs nothing when things go well and saves the property when they don't. The current rules for every market: STR rules by city, with deep dives on Charleston and Myrtle Beach.
Do I need special insurance for a South Carolina coastal rental?
Often, and it belongs in your ratio from day one. Along the coast, standard carriers may decline wind and hail coverage, in which case the SC Wind and Hail Underwriting Association (the "Wind Pool," SCWHUA) writes it as the residual market for eligible areas in Beaufort, Charleston, Colleton, Georgetown, and Horry counties; that policy excludes fire, theft, liability, and flood, which you cover elsewhere. Coastal homeowner and investor policies also carry a separate named-storm deductible, typically 1% to 5% of the dwelling's insured value, triggered by a named storm rather than the flat all-other-perils deductible; on a $300,000 dwelling a 2% named-storm deductible is $6,000 out of pocket before coverage responds. And flood is its own policy entirely, through the NFIP or a private flood carrier, because storm surge is excluded from the wind policy. We never quote a single universal premium, but we do make sure the real coastal insurance stack sits inside PITIA before you call the deal a winner.
Accommodations tax and your loan
Qualifying revenue is gross rent before accommodations tax, so the 7% state rate (5% sales plus 2% state accommodations) and any local accommodations tax do not shrink the ratio. They belong in your operating model, along with the permit fees and, on the Grand Strand, the Horry County hospitality-fee account. Platforms collect and remit some of these on marketplace bookings; your remaining job is the local registration and the bookkeeping. Full tax picture: rental property taxes.
No pressure, no obligation, and no salesy follow-up: a 20-minute call with our team, real numbers, and a straight answer on whether the deal pencils.
Frequently asked questions
Can I finance an Airbnb with a DSCR loan in South Carolina?
Yes. An operating STR with 12 months of platform statements qualifies on its trailing revenue. A property without history qualifies on the appraiser's market rent, or on a revenue projection with a haircut (commonly 20–25%) under some programs. Down payment and reserves scale with how aggressive the income documentation is, and we verify the permit path first.
Do I need special insurance for a South Carolina coastal rental?
Often yes. Coastal properties in Beaufort, Charleston, Colleton, Georgetown, and Horry counties may need the SC Wind Pool (SCWHUA) for wind and hail when standard carriers decline, plus a separate named-storm deductible (typically 1–5% of dwelling value) and a separate flood policy through the NFIP or a private carrier. We build the real insurance stack into your PITIA rather than quoting a universal figure.
Do I need my STR permit before I apply for the loan?
Not necessarily before applying, but the property's permit path must be real before closing: right jurisdiction, right zone or category, available capacity, fees budgeted. Where a regime is uncertain (Folly Beach's review, Charleston's proposals, Hilton Head's new rules), we structure the loan to qualify on long-term rent so the deal doesn't depend on a vote.
How does South Carolina's accommodations tax affect my loan?
It doesn't reduce qualifying revenue: underwriting uses gross rent before the tax. It belongs in your operating model, though: 7% total at the state level (5% sales plus 2% state accommodations) on stays under 90 days, plus local accommodations tax up to 3% cumulative, and on the Grand Strand a Horry County hospitality-fee account on top.
