What it really costs to own 3711 Duck Avenue
The parts of the monthly number a mortgage calculator leaves out, from this listing's MLS record, the county tax roll, Citizens and FEMA. Property facts only.
| HOA dues | The listing states there is no HOA. |
|---|---|
| Home and flood insurance | The average Citizens Property Insurance premium in Monroe County is $4,380/yr (1,542 policies, Citizens detail by county, April 2026); private-market quotes differ by roof age, wind mitigation and distance to the coast. The page's modeled range for this home is $4,000–$8,500/yr; neither is a quote. |
| Roof and age | Built in 1963. An original roof would be about 63 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report and ask for the roof permit date. |

Monroe County is on the Florida coast; wind coverage is a major part of the premium. Premiums and coverage vary by home (roof age, wind mitigation, claims history); obtain a quote from a licensed insurer.

Buyer research checklist
Items worth confirming for 3711 Duck Avenue, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1963 (63 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.
- Look up the parcel on FEMA's Flood Map Service Center and confirm with your insurer whether flood insurance is required.
- 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.
- 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 $9,188/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 3711 Duck Avenue and when was it built?
Per the listing record, 3711 Duck Avenue was built in 1963 and has 3 bedrooms and 1.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 3711 Duck Avenue in?
3711 Duck Avenue is in Key West Fwdn Sub (4.0) in Key West, 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 3711 Duck Avenue 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 3711 Duck Avenue differ from the current owner's?
The estimate on this page (about $9,188 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 3711 Duck Avenue in a flood zone?
A flood designation has not been verified for this address. Look up the parcel on FEMA's Flood Map Service Center (msc.fema.gov) and confirm with your insurer.
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.
