NYC Mortgage Math Reference

PMI: When It Applies

Private Mortgage Insurance (PMI) is required on conventional loans when down payment is under 20%. Typical cost: 0.5% to 1.5% of the loan amount per year, added monthly. PMI ends when equity reaches 20% of the original purchase price. For co-op share loans, PMI rules differ by lender; confirm with your loan officer.

Co-op vs. Condo Monthly Costs

A co-op's monthly maintenance typically includes property taxes, building insurance, and your share of the building's underlying mortgage. A condo's common charges cover building operations only; NYC bills you property taxes separately. Comparing by purchase price alone is misleading. Always compare total monthly carrying costs.

Mortgage Recording Tax (NYC)

NYC buyers pay MRT on the loan amount (not the purchase price). Rate: 1.8% on loans under $500,000 and 1.925% on loans of $500,000 or more. Co-op buyers do not pay MRT because co-ops are personal property, not real property. Source: NYC Dept of Finance.

The 28/36 Qualifying Rule

Most lenders apply two ratios: housing costs should not exceed 28% of gross monthly income (front-end DTI), and total monthly debt payments should not exceed 36-43% (back-end DTI). Qualified Mortgage rules cap back-end DTI at 43% for most loans. Co-op boards often use stricter thresholds.

A Note from Milton

These calculators are educational tools. In 25+ years of NYC transactions, I've seen buyers get pre-approved for a certain price, only to find their actual monthly carry is significantly higher once maintenance, taxes, and co-op board liquidity requirements are factored in. Run all three calculators before you settle on a target price, and always compare total monthly cost across property types, not just purchase price.
