Buying a Folly Beach Rental in 2026: Underwrite This Year, Not IOP's

A property two blocks off Center Street doesn't come with a spreadsheet, but every buyer runs one anyway, and the year that spreadsheet gets built on matters as much as the numbers inside it. 2026 is not a normal year to underwrite a Folly Beach short-term rental purchase — a court struck down the town's license cap in August, and council answered with a moratorium on new licenses days later. Any buying analysis that ignores that timeline is building on ground that already moved once this year and could move again, and a buyer who treats it as a footnote is taking on more risk than the spreadsheet shows.

This post walks through what buying a Folly Beach rental actually looks like in 2026: the real revenue range to underwrite, what entry cost and yield questions to ask honestly, and why the moratorium needs to be the first call, not a footnote. None of this is legal or financial advice — it's a framework for asking the right questions in the right order before money changes hands. This is not legal advice.

The revenue range to underwrite: Folly's own year

AirROI's data for Folly Beach shows a typical year around $76,573 across 952 active listings, with occupancy at 43.1% and ADR at $613, for the window running August 2025 through July 2026. That's the number to underwrite against — not Isle of Palms' similar-looking $76,690 figure, which sits on a market with over 200 listings run through Wild Dunes and Avant Stay property management, a fundamentally different listing stock type than an independent Folly cottage.

Supply grew 7.6% year over year in Folly while overall revenue was down 7.8% over the same period — a market absorbing new listings while per-listing revenue softened somewhat. A buyer underwriting a purchase off last year's headline numbers without accounting for that softening risk is pricing the deal too optimistically, and should build a reasonable margin of error into any projection built on this figure.

Entry cost: verify, don't assume

This report doesn't guess a median sale price or an entry cost figure — that number needs pulling from current ZHVI data or recent comparable sales at the time of underwriting, not carried over from a prior year's report or a neighboring town's figures. Folly Beach real estate has its own micro-market dynamics tied to lot size, flood zone, and proximity to the pier and Center Street, and a generic Charleston-area price assumption will miss those specifics.

Given Folly's relatively high ADR against moderate occupancy, gross yield calculations may look thinner than a buyer expects going in — that's worth saying plainly rather than glossing over. A $613 ADR sounds strong in isolation, but 43.1% occupancy means real annual revenue lands well below what a naive ADR-times-365 calculation would suggest, and a buyer should run the actual math against Folly's real occupancy figure, not an optimistic assumption. That single correction — occupancy times ADR times 365, not just ADR alone — is often where an overly rosy purchase pitch falls apart under scrutiny.

The moratorium: call before you sign anything

In August 2026, a Charleston County judge struck down Folly Beach's voter-approved 800-license cap and its registration fee as illegal under state law, and council responded with a temporary moratorium on issuing new short-term rental licenses, reported to run until February 2027 unless extended or until a related study is complete. For a buyer planning to purchase a property specifically to start a new short-term rental, this changes the entire timeline of the deal.

Before signing a purchase contract on a property intended for new short-term rental use, confirm directly with the City of Folly Beach whether the moratorium currently blocks a new license application for that specific property, and if so, what the realistic timeline looks like for that to change. This is not legal advice — it's a sequencing point that should come before due diligence on the property itself, not after closing.

Buying an already-licensed property is a different calculation

A property that already carries an active, correctly classed Folly Beach short-term rental license is in a meaningfully different position than a property that would need a new license under the moratorium. Confirming that an existing license transfers with the sale, and under what conditions, is a specific question to raise directly with the seller and the city — not an assumption to carry into closing.

This distinction is likely to matter more for Folly Beach buyers in 2026 than in a typical year, since the moratorium makes an already-licensed property meaningfully more valuable, in a practical sense, than a comparable unlicensed one until the city resolves its post-ruling posture.

Wrong buyer: filing IOP's year or skipping the city desk

A buyer who runs their underwriting off Isle of Palms' revenue figures because it's a nearby, similarly sized number is filing the wrong town's year onto this property. IOP's listing stock, guest base, and property-management structure are different enough from Folly's that the two numbers shouldn't substitute for each other in a purchase decision.

Equally, a buyer who skips confirming the City of Folly Beach's current licensing and moratorium status because a real estate listing described the property as 'STR-ready' is taking on real risk. 'STR-ready' from a listing agent is not the same as a confirmed, current license status from the city, especially in a year when the underlying rules just changed twice.

Financing and the moratorium: two separate conversations

A lender evaluating a short-term rental purchase will ask about projected income, and it's tempting to lean on the strongest available revenue figure to make that conversation easier. Resist that instinct with Folly Beach specifically this year — a lender who later discovers the property's licensing status is uncertain, or that the moratorium affects the buyer's ability to operate as planned, is going to view that as a material gap in the underwriting, not a minor detail.

Financing itself is a separate host-read topic covered elsewhere; the point here is narrower — whatever financing path a buyer pursues, the license and moratorium status needs to be resolved and documented before that conversation, not treated as a detail to sort out after the loan closes.

Seasonal cash flow: what the calendar means for a new owner

AirROI data shows June as Folly's peak revenue month, with May and April building into it, and January as the softest, with February and December rounding out the low stretch. A new owner underwriting cash flow needs to plan for that seasonal shape specifically — a mortgage payment due every month doesn't pause for January's softer bookings, so the underwrite should include a realistic month-by-month revenue curve, not just an annual total divided by twelve.

This matters especially for a buyer financing the purchase with debt service tied closely to expected rental income. A property that looks comfortably profitable on an annual basis can still create a cash-flow squeeze in the trough months if the owner hasn't planned reserves or adjusted expectations for that seasonal reality.

What a reasonable 2026 underwrite actually looks like

A defensible underwrite for a Folly Beach purchase in 2026 starts with the $76,573 AirROI figure as a typical-year revenue anchor, adjusted down somewhat to account for the 7.8% year-over-year softening and the specific property's size and location relative to the island's amenities. It verifies current entry cost against actual comparable sales rather than an assumed median, and it treats gross yield honestly given the occupancy-ADR combination rather than an optimistic best-case scenario.

Critically, it also treats the license and moratorium status as a gating factor that determines the deal's actual timeline, not a formality to handle after closing. A buyer who's done all three of these — Folly's own revenue range, verified entry cost, and confirmed license path — is underwriting this property on its actual 2026 footing, not on a blended assumption or a prior year's stale rules.

Comparing a Folly Beach purchase to Kiawah or IOP as investment alternatives

A buyer weighing multiple Charleston-area coastal markets might reasonably compare Folly against Isle of Palms or Kiawah as alternative purchase targets, and that comparison is legitimate at the market-selection stage, even though this report has been clear that the three shouldn't be blended into one revenue figure once a specific property is being underwritten. Each town represents a genuinely different investment profile: Kiawah's resort positioning and gated structure, IOP's heavy property-management listing stock, and Folly's independent, host-run character.

For a buyer specifically interested in an independent-host model rather than a resort or PM-heavy structure, Folly's profile is the better fit of the three almost by definition — but that fit should be a starting filter for market selection, not a substitute for underwriting the specific Folly property on its own numbers once a purchase is actually on the table.

The appeal and what it means for a multi-year hold

Because the August 2026 ruling striking the license cap may be appealed, a buyer planning to hold a Folly Beach property for several years should think about the range of regulatory outcomes over that horizon, not just the current moratorium snapshot. An appeal could restore some version of the cap, leave the current ruling standing, or resolve in some other way — and a multi-year hold plan should be resilient to more than one of those outcomes rather than betting heavily on a single specific result.

This isn't a reason to avoid buying in Folly Beach — plenty of coastal short-term rental markets have gone through similar regulatory fights and settled into a stable operating picture on the other side. It's a reason to build some flexibility into the underwriting rather than assuming today's exact rules hold unchanged for the full length of a hold period.

A useful exercise for a multi-year buyer is stress-testing the deal against a scenario where the moratorium extends longer than currently reported, alongside a more optimistic scenario where it lifts on schedule or sooner. If the purchase only makes financial sense under the optimistic scenario, that's worth knowing before closing, not after.

A first-time Folly buyer versus an existing host adding a second property

A buyer purchasing their first Folly Beach short-term rental is underwriting against a blank slate — no trailing revenue history of their own, no existing sense of the island's seasonal rhythm beyond what AirROI and this report describe. That buyer should lean more heavily on the market-wide figures and build in a wider margin of error, since there's no personal track record yet to sanity-check the projection against.

An existing Folly Beach host adding a second property is underwriting from a stronger position — they already know their own trailing twelve months, their own guest mix, and how their existing listing actually performed through last year's specific trough and peak. That host should weight their own operating history more heavily than the market-wide AirROI figure when projecting the new property's likely performance, adjusting for any real differences between the two properties rather than assuming identical results.

The moratorium consideration cuts differently for each buyer too. A first-time buyer with no existing Folly license has no workaround if the target property needs a new license under the current moratorium — the deal's timeline is fully exposed to that constraint. An existing host who already holds a license on a different property doesn't get to transfer that license to a second address, so the moratorium exposure is functionally the same for both buyer types on the new purchase, even though the existing host's overall risk tolerance for a delay may be higher given their established income from the first property.

Due diligence checklist specific to this purchase environment

Beyond the standard property inspection and title work any real estate purchase requires, a Folly Beach short-term rental buyer in 2026 should specifically confirm: current license status and whether it transfers with the sale, whether the moratorium affects a new application if no transferable license exists, current lodging tax account status if applicable, and the property's actual trailing revenue history if the seller can provide it, compared honestly against the AirROI market figure.

That last point deserves emphasis — a seller's own reported revenue figures, if offered, should be treated as one data point to verify rather than accepted at face value. Comparing a seller's claimed performance against the broader market's typical-year figure is a reasonable sanity check before finalizing a purchase price built partly on that seller-provided number.

Frequently Asked Questions

How much revenue should I underwrite for a Folly Beach short-term rental in 2026?

AirROI's data shows a typical year around $76,573 across 952 listings, with 43.1% occupancy and $613 ADR. Given a 7.8% year-over-year revenue decline alongside 7.6% supply growth, a conservative underwrite should adjust that figure down somewhat rather than treating it as a floor.

Should I use Isle of Palms' revenue numbers to evaluate a Folly Beach purchase?

No. Isle of Palms carries a heavy resort and property-management footprint that produces a structurally different market than Folly's more independent listing stock. Use Folly's own AirROI figures, not a neighboring town's number, however similar it may look on paper.

Can I get a new short-term rental license for a Folly Beach property I'm buying?

That depends on the current status of the August 2026 council moratorium on new licenses, reported to run until February 2027 unless extended. Confirm directly with the City of Folly Beach before signing a purchase contract intended for new short-term rental use. This is not legal advice.

Does an existing short-term rental license transfer when I buy a licensed Folly Beach property?

This needs to be confirmed directly with the seller and the City of Folly Beach as part of due diligence — it shouldn't be assumed. Given the current moratorium, an already-licensed property is likely more valuable in practice than a comparable unlicensed one until the city's post-ruling posture is resolved.

What entry cost should I assume for a Folly Beach rental purchase?

This report doesn't provide a specific figure — verify current ZHVI data or recent comparable sales at the time of underwriting rather than relying on a prior year's number or a neighboring town's pricing.

Is Folly Beach's gross rental yield strong for buyers?

It depends on the specific purchase price, but the combination of a relatively high ADR ($613) against moderate occupancy (43.1%) can produce a thinner gross yield than a naive calculation might suggest. Run the actual math against Folly's real occupancy figure rather than assuming near-full-year utilization.

What does 'STR-ready' mean on a Folly Beach real estate listing?

It's a marketing description from a listing agent, not a confirmed license status from the city. Always verify current licensing and moratorium status directly with the City of Folly Beach rather than relying on that description alone.

Is Folly Beach's short-term rental market growing or shrinking?

Supply grew about 7.6% year over year in the most recent AirROI data, while overall revenue declined about 7.8% over the same period — a market absorbing new listings while per-listing revenue softened, not a simple growth or decline story.

Should I wait for the moratorium to resolve before buying a Folly Beach property?

That depends on whether the property already carries a transferable license and whether the buyer's plan depends on obtaining a new one. For a purchase specifically intended to start a new short-term rental, confirming the moratorium's current status and timeline with the city should come before signing a purchase contract.

What's the biggest mistake buyers make when evaluating a Folly Beach rental purchase?

Underwriting off a blended or neighboring-town revenue figure instead of Folly's own AirROI numbers, and treating licensing as a post-closing formality instead of a gating factor that, in 2026, directly affects the deal's timeline.
