Destin & Fort Walton Beach second homes & vacation rentals: what to know before you buy

Short-term rental rules in Destin & Fort Walton Beach

Rules depend on the exact city, county and zoning district, and they change. Here’s what the official sources say as of November 2026:

• City of Destin: every single-family home rented to seasonal guests must be registered with the City each year. The application requires a City business tax receipt, a Florida Department of Revenue sales-tax number, a Florida DBPR vacation rental license and a 24/7 responsible party.

• Unincorporated Okaloosa County (including Okaloosa Island) points owners to the state DBPR license and notes the County may require registration and regulate occupancy, parking, trash and inspections. Confirm current requirements with Okaloosa County Growth Management for your parcel; Fort Walton Beach city limits may differ. Source: Okaloosa County: Short-Term Rental Information
• Florida requires a DBPR vacation rental license if you rent an entire unit more than three times a year for stays under 30 days (or advertise it as regularly rented). Source: Florida DBPR: Guide to Vacation Rentals

Summaries, not legal advice. Confirm current rules with the locality, and any HOA or condo association, before you make an offer.

HOA, condo and insurance considerations

Florida coastal properties: get windstorm and flood insurance quotes during due diligence. Flood insurance is required for buildings in high-risk flood areas with federally backed mortgages (FEMA). Condo buyers should also review the association’s rental rules, budget and reserves.

Many vacation communities have HOA or condo rules that are stricter than the city or county: minimum stays, rental registration, guest limits or outright bans. Ask for the governing documents and rental rules before your due-diligence period ends. Lenders review condo projects too, so share the association’s details early.

How the financing usually works

• Mostly your family’s place, occasional renting: usually a second home. Under Fannie Mae’s occupancy rules it must be a one-unit home under your exclusive control, not primarily operated as a rental, and rental income generally can’t be used to qualify.
• Mostly renters: lenders treat it as an investment property, which is underwritten and priced differently, and documented rental income can sometimes help you qualify.
• Resort or condo rental programs that control your calendar can affect second-home eligibility. Share any management agreement with me early.
• Count the cost of two homes: your current payment plus the new home’s taxes, insurance, HOA dues and any rental-license or inspection costs.

Before you write an offer

• Confirm the jurisdiction (city vs. unincorporated county) and zoning district for the exact parcel.
• Check whether a short-term rental permit, license or registration is available for that address, and any cap or waitlist.
• Get the HOA or condo rental rules in writing.
• Price insurance (including flood or wind where relevant) during due diligence.
• Decide honestly how you’ll use it, so the loan is classified correctly from day one.
