Quick Answer: Out-of-state buyers — especially those coming from the Northeast — almost always underestimate a handful of things: insurance costs, the heat, what “Florida” actually means day-to-day, and how different the market dynamics are. Here’s what I see buyers get wrong most often, and how to recalibrate.
1. Underestimating Insurance Costs
This is the biggest one. If you’ve only modeled your monthly payment based on purchase price and mortgage rate, you may be in for a real shock when you see the full PITI (principal, interest, taxes, insurance).
Florida homeowners insurance has risen dramatically over the past several years. Factors that affect your premium:
- Age of roof — Insurance companies increasingly require replacement of roofs over 15–20 years old. Some won’t insure them at all without a replacement.
- Proximity to water — Flood insurance is separate from homeowners insurance. Know which flood zone you’re buying in.
- Construction type — CBS (concrete block and stucco) generally insures better than wood frame
- Wind mitigation features — Impact windows, hurricane straps, and rated garage doors can lower premiums
My advice: before you go under contract, get an insurance quote from a local independent agent. Don’t rely on national aggregator estimates — they’re often wildly inaccurate for Florida.
2. Thinking “Florida Summer” Is Just “Hot”
It’s not just hot. Florida summer — roughly May through October — means:
- Heat index regularly exceeding 100°F
- Afternoon thunderstorms that appear out of nowhere and are intense
- Humidity that makes outdoor activity feel significantly harder than the temperature alone suggests
- Mosquitoes and no-see-ums in wooded areas and near standing water
Most buyers who visit in January, February, or March fall in love. The weather is genuinely exceptional. Those same buyers who move and experience their first full summer sometimes go through a recalibration period. This doesn’t mean Florida is the wrong choice — millions love it year-round — but go in with eyes open.
The flip side: there is no Northeast winter here. That trade is real and significant.
3. Assuming Property Taxes Work Like Home
Florida has some nuances buyers need to understand:
Homestead Exemption: If you establish Florida primary residency and file for homestead exemption, you get a $25,000+ reduction in assessed value for property tax purposes — and the Save Our Homes cap limits how fast your assessed value can grow (3% per year or CPI, whichever is lower).
But: The Homestead cap applies to your assessed value — it does NOT transfer when you buy. You’re purchasing at market value, and your assessed value will be reset accordingly. The cap begins building from your first year of ownership. Don’t assume your taxes will look like the prior owner’s — especially if they’ve had homestead for 20+ years.
Also: CDD fees appear on your property tax bill but are not technically “property taxes” — they don’t benefit from homestead exemption and don’t reset with the cap the same way. Always factor them in separately.
4. Buying in the Wrong Part of the County for Their Lifestyle
St. Johns County is geographically large. “St. Johns County” is not a neighborhood — it’s a county that spans from Jacksonville’s southern border to well south of St. Augustine.
Buyers sometimes:
- Buy in Nocatee because it’s buzzy, then discover their actual life centers around St. Augustine — now they’re 30 minutes from everything they care about
- Buy near St. Augustine for the character, then realize they’ll be commuting 45 minutes north to work in Jacksonville every day
- Choose a community because of amenities, without thinking about school zones
My rule for buyers: start with your anchor points (work location, family, community, schools) and build outward from there. Don’t start with the community and retrofit the lifestyle.
5. Misunderstanding “New Construction” Pricing
In the Northeast, buying new construction often means a custom build with significant buyer input and a clear premium over resale. In St. Johns County’s master-planned communities, new construction from production builders works differently:
- You’re selecting from builder-set floor plans and options packages — not a blank slate
- Base prices don’t reflect actual cost — lot premiums, structural upgrades, and design center selections add real money quickly
- “Base price” marketing can be misleading; a livable home often costs 10–20% more than the advertised starting price
That said, production builder homes are often excellent value when you understand what you’re actually buying.
6. Skipping the Inspection Because It’s “New”
New construction homes still need inspections. Builder quality control varies. Common issues I see:
- HVAC duct problems
- Plumbing rough-in issues
- Grading and drainage problems that aren’t obvious at final walkthrough
- Insulation gaps
Hire an independent inspector — not one the builder recommends — and do both a pre-drywall inspection and a final walkthrough inspection.
7. Not Asking About HOA Financial Health
Every HOA-governed community has reserves (or should). Ask for the HOA financial statements and reserve study before closing. Under-funded reserves mean special assessments are coming. It happens.
Bottom Line
None of these are deal-breakers — they’re just things to know before you arrive, not after. The buyers who thrive in this market are the ones who do their homework on the specifics of Florida ownership, not just the lifestyle.
