Four ways to pay for a typical home in Grand Isle County

For a typical $394,100 home at Freddie Mac's average rate (7.18% as of November 5, 2026) over 30 years. The monthly payment adds principal and interest, the county's property tax, an example homeowners insurance and mortgage insurance when it applies.

  • Cash to close = down payment plus 3% of the price in closing costs (example).
  • Minimum score: FHA requires 580 or higher for the minimum down payment (HUD Handbook 4000.1). * Fannie Mae requires 620 when a loan is underwritten by hand; its automated system has no fixed minimum.
  • The ITIN row is an example with a rate 1 percentage point higher: ITIN loans follow no federal rule and each lender sets its own down payment and rate. Nothing in this table promises an approval.

Is there a flood risk?

FEMA’s maps count no homes in high-risk flood zones in Grand Isle County. That does not mean there is no risk: some areas have no map. Check your address.

  • A high-risk zone (Special Flood Hazard Area) has a 1% or greater chance of flooding each year. (44 CFR 59.1)
  • If the home is in that zone and the loan comes from a regulated lender, federal law requires flood insurance for the life of the loan, in communities that take part in the NFIP. (42 U.S.C. 4012a)
  • Most homeowners insurance does not cover flood damage. (FEMA, FloodSmart)
