Key West Mortgage Strategy Engine
The bank may call it jumbo. The structure may tell a different story.
Run your Key West or Monroe County property through county-line, payment, interest-only, buydown, and program-path logic before deciding the structure. Educational only — not a rate quote or commitment to lend.
Strategy Console
property-location intelligence engineWhat matters most before you go jumbo
- Credit score (FICO). 740+ is already strong pricing — you don’t need 780. Below 740 your rate goes up.
- Down payment. 20% down removes monthly mortgage insurance (PMI). Less than 20% adds PMI.
- Income type. W-2 is full-doc; bank statements / 1099 are Non-QM and price higher.
- County line. Your loan amount vs the property county’s conforming limit sets the review path.
What are you trying to structure?
K West Mortgage serves Key West & Monroe County and all of Florida. Monroe County (Key West) is selected by default — change it above to run another Florida county.

Review My Key West Scenario →Confirm the property county before sending your scenario.
Deterministic engine. We never calculate on a guessed or default county — you confirm the property location first. Not approval, qualification, rate quote, APR, loan estimate, or commitment to lend.
Educational structure estimate only. Not approval, qualification, rate quote, APR, loan estimate, or commitment to lend. County lines use the official FHFA 2026 conforming and HUD/FHA forward limits for Florida counties (Monroe County / Key West and statewide). ZIP lookup uses the official HUD CHUMS ZIP file (single-county auto-detect; multi-county ZIPs ask you to confirm). Verify current FHFA/Fannie/Freddie/HUD values before relying on any figure.
