Monthly payment calculator
Rate: 7.24% 30-year fixed average (Freddie Mac, week of October 29, 2026). Your own rate may differ; you can change it here.
Estimate, not a loan offer. Tax default: the higher of the seller's bill and about 1.9% of price (Florida resets a new owner's assessment). Insurance default: Florida OIR county average with wind, data as of Mar 31 2026. Rate is an assumption; your lender sets the real one. Zach doesn't take lender or title referral fees.
Florida risk facts
- Flood zone
- Zone X: minimal flood hazard (per FEMA map). Outside FEMA's mapped high-risk area. Many flood claims still come from outside high-risk zones, so a quote is worth getting. Source: FEMA National Flood Hazard Layer, checked Oct 28, 2026. This is a map lookup, not an official flood zone determination.
- Wind and building code
- Built in 2002, after the statewide Florida Building Code took effect in 2002. Ask for the wind mitigation report; it can lower insurance. My Safe Florida Home offers free inspections and grants when funded.
- Disclosure
- Florida sellers must give you a flood disclosure about known flood damage, insurance claims and federal assistance (§689.302).
We don't show crime scores or rate neighborhoods. Every listing is open to everyone.
Start an offer
- Pre-approval letter or proof of funds (cash)
- The price you'd offer and your deposit
- Financing type and closing date
- Inspection period you want (often 10-15 days)
- A signed buyer agreement with Zach (Florida practice before touring or offering)
Nothing here is a binding offer. Zach calls you, checks the comps and writes the contract with you.
