Key West jumbo loans.
Financing for Key West homes above the conforming limit — the Old Town historic conch houses, Casa Marina estates, and gated Sunset Key — in Florida's only high-cost county, where the jumbo line is $990,150.
A jumbo loan in Key West is any mortgage above the Monroe County conforming limit — $990,150 for a one-unit home in 2026.
Key West sits in Monroe County, the only Florida county with a high-cost conforming limit — so here the jumbo line is $990,150, not the $832,750 baseline used everywhere else in the state. The market's historic conch-house stock, island flood exposure, and limited inventory shape nearly every file.

What's specific to Key West jumbo files
Monroe County's $990,150 limit
Key West is in the state's only high-cost county, so a loan is jumbo above $990,150 rather than the $832,750 baseline. Confirm the figure for the subject property at fhfa.gov.
Historic conch-house appraisal
Old Town's landmark and historic homes are underwritten with attention to condition, systems, and designation restrictions; the appraisal needs strong comparables.
Island flood & insurance
Flood zone, elevation, and windstorm coverage are central to nearly every Key West file and feed the qualifying payment; price binders early.
How to qualify for a Key West jumbo loan
