Buyer research checklist
Items worth confirming for 440 9th Street, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1995 (31 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
- The listing reports no HOA: confirm with the county record that no deed restrictions or mandatory association apply to this parcel.
- FEMA flood zone AE: lenders generally require flood insurance here — get an elevation certificate and a flood quote before the inspection period ends.
- Get a homeowners insurance quote for this specific address in Monroe County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
- Confirm square footage and room dimensions independently.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $12,285/yr) assumes reassessment at the list price; the seller's current bill is not a guide Exemptions and portability change the actual bill — confirm with the county property appraiser.
- Confirm school zoning directly with the district.

Frequently asked questions
How big is 440 9th Street and when was it built?
Per the listing record, 440 9th Street was built in 1995 and has 3 bedrooms and 2.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 440 9th Street in?
440 9th Street is in Key Colony Bch 1st Addn Amd Plat (53.5) in Key Colony, Monroe County. Too few comparable closed sales exist nearby for this page to show local sales statistics; a licensed agent can prepare a comparative market analysis.
Does 440 9th Street have an HOA?
The listing reports no HOA. Confirm with the county record that no deed restrictions or mandatory association apply to the parcel.
Why might property taxes on 440 9th Street differ from the current owner's?
The estimate on this page (about $12,285 per year) assumes reassessment at the list price less the homestead exemption. Florida reassesses a home after it sells; for a homesteaded seller the Save Our Homes cap on their assessment does not transfer, and a buyer's own exemptions and portability are applied separately, so the two bills usually differ. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 440 9th Street in a flood zone?
The FEMA flood map places this parcel in Zone AE, a special flood hazard area where lenders generally require flood insurance on a mortgaged purchase. Confirm the parcel's status with FEMA and your insurer, and ask for an elevation certificate.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.
