Higher is a better buy. 50 is "priced about right for what it is". The last step curves the raw advantage onto 0–100, so points stop being one-for-one at the extremes.
💵What this unit actually costs per month
26% of that payment is not the mortgage. The HOA fee alone is $66,780 over five years — money that buys you no equity. A calculator that defaulted the fee to zero would have quoted you $9,288.
Not FHA-approved. No 3.5%-down FHA financing on this unit, so the realistic floor is a 5%-down conventional loan ($69,750). Common for small associations and not a defect on its own, but it does remove FHA buyers from your resale pool.
