Most of the housing stock dates to the 1950s and 1960s, and current listings and recent sales in the area have generally run from around 800 to a little over 1,600 square feet, with 2 to 3 bedrooms.

County records show 45 qualified sales in River Forest across 2024–2025 (34 in 2024, 11 in 2025), median $225,000 — the last recorded sale per parcel on the Florida DOR 2025 assessment roll, independent of the MLS.
Because nearly every home here is decades old, condition, updates, and lot position do more work than floor plan in setting price. Buyers should expect a mix of untouched and recently renovated homes on the same street, and should budget for the age of major systems, roof, and windows unless a listing documents otherwise.
No homeowners association or Community Development District has been identified for this neighborhood, so ongoing carrying costs are largely property taxes, insurance, and any maintenance the home itself needs, rather than a fixed HOA line item. Confirm both on the specific parcel with the Duval County Property Appraiser before you buy.
