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 AE: high-risk flood area. A FEMA Special Flood Hazard Area (about a 1% chance of flooding each year). Lenders require flood insurance for federally backed mortgages here. 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 1999, before 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

  1. Pre-approval letter or proof of funds (cash)
  2. The price you'd offer and your deposit
  3. Financing type and closing date
  4. Inspection period you want (often 10-15 days)
  5. A signed buyer agreement with Zach (Florida practice before touring or offering)

Rather not check the box? That's fine. Zach will call or email instead.

Zach will reply as soon as he can. Your info goes to Zach only. Never sold, never shared. You choose how he reaches you, and STOP always works.

Nothing here is a binding offer. Zach calls you, checks the comps and writes the contract with you.
