Cost of Living & Housing in Key West
Key West is one of the most expensive places to live in Florida on every cost dimension researched here -- housing, everyday expenses, and insurance -- a direct consequence of the roughly 4-square-mile island's hard physical land-supply ceiling, per the base place record.

The base place record cites a median sale price near $1.26M (up 28% YoY over a trailing three months ending June 2026, per Redfin), with median price per square foot ($819) moving in the opposite direction (down 9.9% YoY) -- a pattern consistent with a thin, low-volume luxury market where a handful of high-value closings can swing the median sharply. A separate aggregator cited $1,135,000 (up 19.5% YoY) for a nearby window, broadly consistent in direction and magnitude. Because the island has essentially no room for new development, this is described as a structural, supply-driven premium rather than a cyclical bubble likely to correct.
Everyday cost of living
Key West's cost-of-living index runs about 172 against a national baseline of 100 (about 42% above average), consistent across multiple sources. Grocery and food costs run about 5% above average ($420/month for a single adult, $1,365/month for a family of four in one estimate), and energy, transportation, and healthcare costs run about 6.7% higher than the national average by the same source. For a larger waterfront property, one estimate put monthly groceries alone at roughly $850.
Insurance -- the widest-ranging cost figure
Reported homeowners insurance costs for Key West vary enormously depending on the source and coverage type: Citizens Property Insurance (the state-backed insurer) averages about $4,380/year for Monroe County policies, one broader estimate puts the Key West average around $9,835/year, and a private-market quote-based source cited $25,080/year for $300,000 in dwelling coverage with a $1,000 deductible. For comparison, Florida's statewide homeowners insurance average runs around $6,300-$10,384/year depending on source. This is a genuinely wide, disclosed range rather than one reliable figure -- get a property-specific quote, and expect it to vary sharply based on construction, flood zone, and whether coverage comes from Citizens or a private carrier.
Key takeaways
- Median sale price runs roughly $1.14M-$1.26M depending on source and window -- among the highest in Florida, driven by the island's hard, roughly 4-square-mile land-supply ceiling rather than speculative demand.
- Key West's cost-of-living index runs about 42% above the national average, consistent across sources -- a real, sustained premium, not a one-time reading.
- Homeowners insurance figures vary by more than 5x across sources ($4,380/year via Citizens to $25,080/year for a private quote on $300K coverage) -- treat any single number with real skepticism and get a property-specific quote.
- Reported price-per-square-foot fell even as the median sale price rose sharply -- a sign of a thin, low-volume luxury market where individual high-value sales can swing headline figures, not a stable trend to extrapolate from.
