Roughly 1 in 3 first-time NYC buyers lose their first deal to a preventable mistake, whether it is a rejected co-op board package, an expired pre-approval, or underestimating closing costs by $30,000 or more. After helping hundreds of first-time buyers close in Manhattan, Brooklyn, and Queens over my 25+ years as a licensed associate broker (NY #10401274378), these are the seven mistakes I see most often and exactly how to avoid them.

1. Not Getting Pre-Approved First

Many buyers start searching before knowing what they can afford. Get pre-approved before you fall in love with a property you can't buy.

2. Underestimating Co-op Requirements

Co-ops often require:

3. Ignoring Closing Costs

Budget 2-6% of purchase price for closing costs, including attorney fees, mansion tax (over $1M), and various fees.

4. Skipping the Building Research

5. Not Hiring a Buyer's Agent

A buyer's agent costs you nothing (the seller pays) and provides expert guidance, negotiation, and access to listings.

6. Making Emotional Decisions

Stay objective. The right property meets your needs, fits your budget, and makes financial sense.

7. Waiting for the "Perfect" Time

There's no perfect time to buy. Focus on finding the right property at a fair price.
