Harlem
A rapidly shifting market — new-construction condos from the 2010s–2020s sit alongside HDFC co-ops, brownstone conversions, and sponsor-controlled buildings still inside the Martin Act window. Harlem is the neighborhood where thorough due diligence separates real value from buried risk.
Building Stock
Mixed: (1) New-construction condos on 125th, Frederick Douglass Boulevard, and Adam Clayton Powell Jr. Boulevard, (2) HDFC income-restricted co-ops (~15% of Harlem co-op stock), (3) prewar rental-to-condo conversions, (4) brownstone and rowhouse subdivisions. Each tier carries distinct legal constraints.

Key Issues to Watch For
- HDFC buildings have income caps and flip taxes — verify you qualify and understand the resale math before bidding.
- Newer condos often still have sponsor board control; board turnover events can trigger unexpected assessments.
- Some converted brownstones have unresolved Certificate of Occupancy issues — pull the BIS record.
- 421-a abatements on new construction are expiring in clusters; model the tax reset 5–10 years out.
Local Law 11 / FISP Exposure
Harlem's older prewar stock has lower FISP compliance rates than the UES/UWS — and facade reports are often thinner than they should be. Don't accept a summary; read the inspector's full report and photos.

Before You Sign a Contract
- Pull the building's record — use our building search to get HPD violations, DOB complaints, managing agent history, and composite risk.
- Read the full offering plan and last three annual financial statements — don't accept a summary.
- Check the reserve fund — benchmarks vary by building age and size, but thin reserves are the canary for upcoming special assessments.
- Ask about upcoming capital projects — facade, elevator, lobby, roof, mechanical — and pin down the budget.
- Verify the tax abatement status — if 421-a or another abatement is expiring, model the reset on your carrying costs 5 and 10 years out.
- Search NYSCEF for active litigation — against the board, the managing agent, or the sponsor LLC.
