About this home
Set on a quiet, tree-lined block in one of Key West's most sought-after residential pockets, this thoughtfully reimagined 4BD/3BA residence offers just over 2,000 square feet of refined island living -- the result of a multi-year renovation where no detail was overlooked. The first floor opens to a flexible bedroom or private office alongside a full bath, newly converted and finished to the same standard as the rest of the home. Beyond, an all-new updated kitchen anchors the space with stainless appliances, custom built-in cabinetry, fresh countertops and designer lighting.
French doors wrap the open living room, flooding the interior with natural light and dissolving the line between inside and out. Step through to your private tropical oasis: a heated pool, newly resurfaced and framed in travertine, with a new outdoor shower for rinsing off after a day at the beach. A setting built equally for quiet mornings and evenings.
Upstairs, the primary suite delivers an ensuite bath, walk-in closet and a private balcony made for morning coffee above the palms. Two additional guest bedrooms and a full guest bath complete the second floor. Behind the finishes, the seller has invested in everything that matters: new HVAC, on-demand hot water, all-new pool equipment, new tile flooring, baseboards and lighting throughout, plus fresh interior and exterior paint.
Renovated bathrooms and updated floors carry the same considered hand from room to room. A short bike ride delivers you to Key West's finest restaurants, beaches, galleries, museums and world-famous Duval Street -- yet the block itself stays wonderfully removed from it all. A neighborhood stunner not to be missed.

Property taxes
✓ Certified tax roll · county-average rateProperty taxes in Florida are reassessed after a sale, so a buyer’s first full-year bill can be higher than the seller’s. Budget from this estimate, not the current bill, before you make an offer.
The current owner’s taxable value is below today’s asking price; after a sale the assessment is set from market value, so the estimated bill is higher. Exemptions and portability can reduce it.

What it really costs to own 1427 Washington Street
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.
| Property tax | The current owner's bill is about $9,475/yr (certified county roll, taxable value × millage). Buy at the asking price of $2,525,000 and the first-year bill resets to about $21,825/yr (the parcel is matched to the certified roll; asking price less the $50,000 homestead exemption × 8.82 mills (county-average millage, estimate)); Save Our Homes caps later increases at 3%/yr. |
|---|---|
| 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 $9,500–$20,000/yr; neither is a quote. Flood: this address maps to FEMA zone AE, a high-risk zone where flood insurance is required with a federally backed mortgage. Statewide, a zone A/AE/VE flood policy runs about $1,200–$2,500/yr (FEMA Risk Rating 2.0 averages, not a quote). |
| Roof and age | Built in 1998. An original roof would be about 28 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. |
Estimated carrying cost at the asking price, before the mortgage: about $2,184/month (tax $1,819, insurance $365). An estimate from the sources above, not a quote; the monthly-cost calculator on this page adds the loan.

Buyer research checklist
Items worth confirming for 1427 Washington Street, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1998 (28 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.
- Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
- 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 $21,825/yr) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $12,350 more per year than the current owner’s estimated bill (+130%). 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 1427 Washington Street and when was it built?
Per the listing record, 1427 Washington Street was built in 1998 and has 4 bedrooms and 3.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 1427 Washington Street in?
1427 Washington Street is in Tropical Bldt & Investment Co Sub (2.0) 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 1427 Washington 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 1427 Washington Street differ from the current owner's?
The estimate on this page (about $21,825 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $12,350 more per year than the current owner’s estimated bill (+130%). 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 1427 Washington 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.
