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
44% of that payment is not the mortgage. The HOA fee alone is $64,620 over five years — money that buys you no equity. A calculator that defaulted the fee to zero would have quoted you $2,355.
Not FHA-approved. No 3.5%-down FHA financing on this unit, so the realistic floor is a 5%-down conventional loan ($17,400). Common for small associations and not a defect on its own, but it does remove FHA buyers from your resale pool.

This building's HOA fees
🚩 Rising fast · +7.5%/yrReconstructed from 18 units of recorded sales at 311 Oak St — every recorded sale carries its HOA fee and date. No listing site shows this.
These dues climbed 43% in 5 years — about +7.5%/yr across 18 units of recorded sales, well above inflation. A rise this steep is a leading signal of a special assessment, a drained reserve fund, or an insurance shock. The listing never shows it; the building's documents are where the "why" lives.
