Quote the address,
never the region
Insurance is the one operating cost that varies more by individual property than by market. In Florida and other coastal states it decides whether an otherwise sound rental works at all.
Before you read on
- General information as of August 2026, not insurance advice. Obtain a written quote for the specific address before committing to a purchase.
- Premiums, availability and carrier appetite change frequently, particularly in coastal markets.
- A lender will require coverage as a condition of the loan. Confirm insurability before you rely on financing.
Point 1What actually drives the premium
Six variables, none of which appear in a listing.
| Variable | Why it moves the premium |
|---|---|
| Roof age and material | The single largest factor on older houses. Some carriers decline above a certain age |
| Construction type | Masonry against frame changes both fire and wind exposure |
| Distance to coast | Wind and storm surge exposure, priced in bands rather than smoothly |
| Flood zone designation | Affects premium, requires separate flood cover, and can be a lender condition |
| Claims history | On the property and in the area. Repeated claims raise premiums permanently |
| Occupancy type | Landlord policies differ from owner-occupier cover and generally cost more |
Two identical houses on the same street can carry different premiums because of roof age alone.
This is why a regional assumption is worthless in underwriting. An investor modelling Florida from a spreadsheet built for Ohio will produce a return that does not exist, and the error is discovered after closing rather than before.
Point 2What it does to a rental return
Miami shows a 6.19% gross yield. After a real insurance quote, county tax without homestead, management and vacancy, the unlevered net commonly lands between 3% and 4.5%.
Lenders include insurance in the debt service coverage calculation. A high premium can push an otherwise qualifying deal below the required ratio.
The association insures the building; the owner insures the interior and liability. Read what the master policy actually covers before assuming.
Coastal policies frequently apply a percentage deductible on named storms rather than a flat sum, which is a much larger exposure than it appears.
Standard homeowner cover excludes flood. Separate cover is required, and in some zones a lender will insist on it.
A carrier may decline renewal after a claim or a market shift. Budget for the possibility of repricing rather than assuming continuity.
Point 3Florida and the condominium reserve question
Insurance and reserves became the same conversation after 2021.
Florida strengthened its requirements for condominium structural inspections and reserve funding following the 2021 Surfside collapse. Associations that had underfunded reserves for years have had to raise contributions or levy assessments, and buyers have inherited both alongside a repriced insurance market.
For a Florida condominium the document review is therefore inseparable from the insurance question: the reserve study, the current balance, any structural inspection reports, and the minutes covering how the association responded. A low monthly fee in an older coastal building is frequently a deferred bill.
Point 4The sequence that avoids the surprise
Obtain a written quote for the specific address before going firm, not after. Confirm the flood zone designation, because it affects the premium, the requirement for separate cover and sometimes the lender’s willingness to proceed. Establish the roof age at inspection, since it is the variable that most often determines both price and insurability.
Then put the real figure into the model rather than a placeholder. In high-premium markets this single discipline reorders shortlists more reliably than any other check, because the properties that look cheapest on price are frequently the ones carrying the oldest roofs.
There is no useful national figure. It varies by address, construction, roof age and flood zone. Obtain a written quote before committing rather than using a regional average.
Hurricane exposure and reinsurance costs have repriced the market. Coastal properties in particular can face premiums that materially change the annual carrying cost.
Partially. The association typically insures the building structure; the owner insures the interior, contents and liability. Read the master policy to establish the boundary.
No. Standard homeowner policies exclude flood, and separate cover is required. In some flood zones a lender will make it a condition of the loan.
Yes. Lenders require coverage, and in DSCR underwriting the premium feeds directly into the coverage ratio the property must clear.
Coastal policies often apply a deductible as a percentage of insured value for named storms rather than a flat amount, which can be a substantial sum on a claim.
