The Hidden Costs of Owning an Investment Property in St. Augustine

Owning an investment property in St. Augustine can seem like a dream — after all, who wouldn’t want to stake their claim in one of Florida’s most charming and historic coastal cities? But before you count your rental income, it’s important to understand the full financial picture. While real estate in our area can appreciate nicely and generate steady returns, there are hidden costs that can erode your profit if you’re not careful. Here’s what every investor should factor in:

1. Property Taxes and Homestead Exemptions

Florida offers valuable tax exemptions for primary residences — but those disappear for investment properties. In St. Johns County, short-term rental owners have reported significant tax hikes after losing the homestead exemption. If you rent out your property more than 30 days per year over two consecutive years, it can be reassessed at a higher market rate. That means higher property taxes that will grow faster over time.

Tip: Consult with your tax advisor to understand how a rental could affect your exemption and what to budget for annually.

2. Insurance Premiums in Coastal Zones

St. Augustine’s beautiful coastline comes with a risk premium. You’ll likely need windstorm coverage, flood insurance (unless your property is located in Flood Zone X), and extended liability protection — especially if you’re hosting short-term guests. Most investors pay well above the state average in insurance premiums, and rates have been steadily climbing due to recent storm activity.

Stat: Average annual insurance cost in Florida is over $4,000, but for coastal vacation homes, it can exceed $6,000–$8,000 depending on zoning.

3. Maintenance and Unexpected Repairs

Historic homes and ocean air create the perfect storm for wear and tear. From corroded AC units to wood rot and salt-damaged windows, it’s wise to set aside at least 1–2% of the property value annually for maintenance. And in rental-heavy zones, the pace of repairs can be faster than in primary residences.

Mistake to Avoid: Ignoring small issues now often leads to bigger, more expensive repairs down the road. 

4. Property Management Fees

Unless you're local and handling bookings yourself, you'll likely hire a property manager. For long-term rentals, expect to pay 8–12% of monthly rent. For short-term rentals, however, that number jumps significantly — often 20–30% of gross revenue — due to the increased turnover, guest communication, and cleaning coordination.

Actionable Tip: Interview multiple management companies and compare what services are included in their base fee.

5. HOA Fees and Restrictions

Many beachside neighborhoods and condo communities have monthly HOA dues that range from $100 to $500+. These cover community amenities and upkeep, but may also come with strict rental rules — some even ban short-term rentals altogether.

Pro Tip: Always verify rental policies in the HOA documents before purchasing.

6. Vacancy Periods and Seasonality

Tourism ebbs and flows in St. Augustine. While summers, holidays, and spring break bring high occupancy, the off-season can result in gaps. Vacancy means no revenue, but expenses like insurance, taxes, and HOA fees keep coming.

Stat: St. Augustine averages a 40–50% occupancy rate annually for vacation rentals, depending on location and management.

7. Regulatory Compliance and Licensing

The short-term rental market in Florida is under increasing scrutiny. You’ll need a state license, business tax receipt, and a local short-term rental certificate that must be renewed each year. You also will have to pay monthly state and local tourist development taxes. Properties must also comply with local safety codes, occupancy limits, and parking regulations.

Mistake to Avoid: Don’t list your home on Airbnb without confirming you're compliant — fines can be steep.

8. Extra Expenses for Short-Term Rentals

Short-term rentals are a different beast altogether when it comes to cost and operations. Here’s what to budget for:

• Turnover Cleaning: $100–$200+ per stay, depending on size and linens.

• Consumables: Toiletries, paper goods, etc. can add up monthly.

• Furnishing & Decor: Vacation rentals must be fully furnished with modern, durable pieces — and refreshed regularly to stay competitive.

• Technology & Subscriptions: Smart locks, security systems, Wi-Fi, cable or streaming services, and guest apps are all standard now.

• Platform Fees: Airbnb, Vrbo, and booking channels take 3–15% of each reservation.

• Marketing & Photography: Professional listing photos, SEO-optimized descriptions, and booking-site optimization are crucial to stand out.

Tip: Build a spreadsheet to track these variable costs month-by-month — it will give you clarity on your actual net income.
