What to check on this one

  • Confirm flood zone designation and elevation certificate requirement for St. Johns County
  • Verify HOA $64/mo covers what; request Treaty Oaks CC&Rs and rental restrictions
  • Get roof age/warranty documentation; home is 7 years old, confirm 2019 install date
  • Review assumable FHA mortgage terms with lender—verify buyer qualification and transfer process
  • Request 4-point inspection if lender requires; standard for older FHA assumptions in Florida

Flagged from the listing itself — not an inspection, and no substitute for one. Bring these to the showing.
