4414 Shamrock Ave S, Jacksonville, FL 32218 is a 3-bedroom, 2-bathroom single-family home with 1,546 square feet, a 2-car garage, slab foundation, city water, public sewer, no HOA, and no flood zone. The entire HVAC system was replaced in March 2026 -- new outdoor condensing unit on a new concrete pad, new indoor air handler, all-new refrigerant lines in both directions, and new ductwork from the air handler into the attic -- carrying a 10-year manufacturer warranty and two complimentary service visits included during the first year of ownership. In Florida, where air conditioning runs most of the year, a brand-new system under warranty removes the largest mechanical concern a buyer typically inherits in a 1990s home. No HOA means no monthly dues, no rental restrictions, and no approval process for improvements or tenants. The property is out of the flood zone, so standard homeowner insurance applies -- no separate flood policy required. City water and public sewer with no well or sept ic
