💵What this unit actually costs per month
21% of that payment is not the mortgage. The HOA fee alone is $55,080 over five years — money that buys you no equity. A calculator that defaulted the fee to zero would have quoted you $19,526.
Not FHA-approved. No 3.5%-down FHA financing on this unit, so the realistic floor is a 5%-down conventional loan ($149,750). Common for small associations and not a defect on its own, but it does remove FHA buyers from your resale pool.
