What renovation permits are required?

Most significant work requires DOB filing. Type 1 alteration permits cover use/egress changes. Type 2 covers general interior alterations including gut renovations. Co-op boards add another layer with alteration agreements and contractor insurance requirements.

How do I finance a fixer-upper in NYC?

Standard co-op/condo mortgages don't include renovation costs. Buyers typically finance renovations through a HELOC after closing, a renovation loan, or cash reserves. Before making an offer, establish your renovation budget, add a 15-20% contingency, and confirm you have sufficient liquidity.

What should I inspect before buying?

Beyond standard inspection, check DOB open permits and violations at nyc.gov/buildings, test for asbestos and lead paint in pre-1978 buildings, verify electrical panel age and amperage, and assess cast iron or galvanized plumbing condition. Open DOB violations can delay closing.

Buying Tip from Milton Coste

Calculate the After-Repair Value (ARV) first: what comparable renovated units have actually sold for in the last six months. Subtract your renovation cost plus a 20% buffer, then subtract your equity cushion. If the purchase price doesn't allow that math to work, walk away. I've seen buyers overpay because they anchored to the asking price instead of the ARV.
