You’ve finally found the Manhattan apartment that checks all your boxes. The price fits your budget, the location is ideal, and you’re ready to make an offer. Yet, the deal unravels — and almost always for the same two preventable reasons: moving too slowly, and working with attorneys and lenders who don’t know the Manhattan market.

This scenario is more common than most buyers realize, and it’s almost always preventable.

Justin Neissani, a licensed real estate salesperson with The Corcoran Group, has helped buyers close deals across Manhattan, from entry-level studios to multi-family buildings. Here, he walks through the most common reasons transactions fall apart — and what buyers can do before they even start searching to make sure their deal closes smoothly.

Time and Team

It’s not low appraisals or last-minute financing issues that most often sink deals in Manhattan. According to Neissani, “The number one killer of deals is time.” The longer a transaction takes, the greater the risk that uncertainty, market changes, or second thoughts will derail it. Sellers lose confidence and start entertaining backup offers. Buyers get cold feet. Rate locks expire. And in a market as fast-moving as Manhattan’s, even a few weeks of unnecessary delay can mean losing a property you were days away from closing on.

The root cause of most delays is an inexperienced team. Buying property in Manhattan is more complex than in most other markets. Co-op purchases require detailed financial disclosures and board approval. Condo transactions demand careful review of building financials and reserve funds. Multi-family properties introduce issues like rent rolls, tenant leases, and zoning regulations.

A single weak link can bring an otherwise solid deal to a halt — an attorney who doesn’t regularly handle Manhattan transactions may slow the process by asking basic questions or requesting unnecessary paperwork. A lender unfamiliar with co-op board standards may fail to prepare your financial documents in the right format. The best brokers work to close those openings before their clients ever notice. As Neissani puts it, “If you’re not hearing about any problems, that means your broker is doing an amazing job.”

Building a Team That Closes Deals

The most effective way to avoid these pitfalls is to assemble your team before you start looking at properties — not after you’ve found a place you want.

Choose a Broker with Local Expertise. Don’t base your broker decision on online presence or flashy listings. Select a broker who specializes in your target neighborhood and price range. They should know recent comparable sales, the reputations of specific buildings, and common issues that arise in local transactions. Ask how many deals they’ve closed in the past year and whether they have repeat clients, which is a strong sign of reliability and expertise.

Hire an Attorney Who Knows Manhattan. Your attorney should regularly close Manhattan co-op and condo deals. Ask about their experience with local board packages, their typical turnaround time for contract reviews, and their knowledge of building-specific requirements. A slow or inexperienced attorney can add weeks to your timeline, giving sellers opportunities to consider backup offers or walk away.

Work with a Lender Who Knows the Market. Not all lenders are equipped to handle Manhattan’s distinctive requirements. Find a lender who routinely works with Manhattan buyers and understands how to prepare your financials for board approval. Many lenders are used to straightforward suburban mortgages and may be unfamiliar with co-op board scrutiny or building financial reviews. Get pre-approved before you begin your search: this signals to sellers that you’re serious and allows you to move quickly when you find the right property.

What Buyers Should Do

If you’re planning to buy in Manhattan, take these steps before you schedule any showings:

• Interview Multiple Brokers: Ask about their experience in your target neighborhood, their average time from offer to close, and how they handle problems during transactions.
• Get Referrals for Attorneys and Lenders: Ask your broker for recommendations, but also do your own research. Check reviews, verify their experience with Manhattan transactions, and ensure they respond promptly to inquiries.
• Understand the Full Timeline: Have your broker outline the entire process — from making an offer to closing — so you know what to expect. Co-op board approvals can take weeks, and financing can encounter delays. Build extra time into your plans to avoid surprises.
• Be Ready to Act Quickly: Once you have a strong team in place, you can move fast without missing critical steps. In Manhattan’s market, speed is essential, but it’s only effective if your team can execute without errors.
• Don’t Skip the Inspection: For condos and multi-family properties, a thorough inspection can reveal expensive issues before you commit. Even in a competitive market, most sellers will allow at least an informational inspection. Forgoing this step to make your offer more attractive is risky and can lead to costly surprises after closing.

The More Things Change…

Manhattan’s real estate market remains competitive and fast-moving, but deals are increasingly at risk due to preventable delays and missteps. Assembling the right team before you begin your search is the most effective way to avoid costly setbacks. “Learn about your timelines, put together a good plan, and educate yourself before you jump into things,” Neissani advises. With the right broker, attorney, and lender, you’re far more likely to close smoothly — and avoid the frustrations that derail too many Manhattan buyers.
