Cap rate is the number most investors ask for first, and it's also the number that misleads the most in this market. In Cape Coral, Fort Myers, and Naples, insurance cost swings so widely property to property that two homes with identical rents and purchase prices can land in completely different places once you actually run the numbers. Here's the framework we walk investors through before they make an offer.
Start with insurance, not rent
Most investors build their model around rent first and treat insurance as a rough estimate to fill in later. In this market, that order should flip. Get an actual quote — not a percentage-of-value estimate — on the specific property before you finalize any cash flow projection. Flood zone, roof age, construction type, and distance to the coast all move this number meaningfully, and it's frequently the single largest swing factor in whether a deal cash flows or doesn't.
Non-owner-occupied pricing is its own category
Insurers frequently price investment property differently than an owner-occupied primary residence, and the gap surprises investors who are pricing off what they pay on their own home. Two nearly identical houses — one owner-occupied, one a rental — can carry noticeably different premiums. Underwrite the property as what it will actually be, not as a stand-in for a home you'd live in.
The cap rate you calculate before getting a real insurance quote is a guess. The one you calculate after is a number you can actually underwrite against.
Build the real expense stack
Beyond insurance, the expenses that most often get underestimated in Southwest Florida rental underwriting:
- HOA or condo association fees — and whether they're trending up, since reserve-funding requirements have pushed many associations to raise dues or levy special assessments in recent years
- Property management, typically around 8–10% of collected rent if you're not self-managing
- Vacancy and turnover, which behaves differently across a seasonal market than a flat annual assumption suggests
- Maintenance reserves, weighted toward roof, HVAC, and exterior — the systems that take the most direct hit from Florida's climate
Where cash flow actually differs — Cape Coral, Fort Myers, Naples
These three markets don't behave the same way for an investor. Cape Coral offers more inventory at a lower entry price point, often with better raw cash-on-cash numbers on paper. Fort Myers spans a wider range of submarkets and price points, so the numbers vary block to block more than city to city. Naples carries the highest entry price and the strongest rent ceiling, which tends to favor appreciation-focused investors over pure cash-flow buyers. None of these is automatically the "right" answer — it depends on which side of the cash-flow-versus-appreciation trade-off you're optimizing for.
The playbook, step by step
- Get an actual insurance quote on the specific property before modeling cash flow
- Confirm HOA/condo rental restrictions and recent or pending special assessments
- Price property management in, even if you plan to self-manage initially
- Model vacancy against the real seasonal rental curve for that specific submarket, not a flat annual average
- Decide up front whether you're optimizing for cash flow or appreciation — the right city and property type differ depending on the answer
The bottom line
The deals that actually work in this market are the ones underwritten with real insurance numbers and a full expense stack from the start, not the ones that look best on a rough back-of-envelope cap rate. Run the real numbers before you fall in love with the property.
