What You Need to Know About Buying a New Development Property in NYC

Purchasing a new development property in New York City offers an exciting opportunity to be the first to live in a brand-new space, often with modern layouts, energy-efficient features, and high-end amenities. But the process is not the same as buying a resale apartment—and first-time buyers especially need to be aware of the nuances that come with purchasing in a new development.

Here's what you need to know before taking the plunge.

1. Expect to Pay a Premium for “New”

New development properties typically come with a higher price per square foot than comparable resale units in the same neighborhood. Why? You’re paying for everything from untouched finishes and the latest appliances to state-of-the-art amenities, new infrastructure, and often, a desirable location.

This “newness premium” can be worth it if you value minimal maintenance, clean lines, and modern design—or if you believe the building (or area) has strong upside potential.

2. Be Prepared for Early Buying: Buying Off Floorplans

Many new developments are sold before they are completed—sometimes before a shovel even hits the ground. This means you’ll often be reviewing floorplans and renderings rather than walking through a finished apartment.

It’s important to work with an experienced agent who understands layouts, finishes, building history, and construction timelines. Your agent can help you evaluate light exposure, ceiling height, storage, resale potential, and more—all from just the plans.

3. Closing Costs Are Higher Than Resale

New development buyers in NYC generally face higher closing costs, including:

• NYC and NYS transfer taxes (typically paid by the seller in resales, but passed on to the buyer in new developments unless negotiated otherwise)

• Sponsor attorney fees

• Working capital contributions to the building’s reserve fund

• Mansion tax if the purchase price is over $1 million

Make sure to budget for an additional 4–6% of the purchase price in closing costs. In some competitive projects, sponsors may offer closing cost concessions or pay transfer taxes as an incentive.

4. The Offering Plan Is Your Bible

New developments in NYC are governed by an official document called the Offering Plan, which discloses everything from square footage and ceiling heights to common charges, building rules, and anticipated completion dates. While dense and legalistic, this document outlines exactly what you’re buying.

Before signing a contract, your attorney will review the Offering Plan to confirm that what’s being marketed is legally accurate and fair.

5. The 421-a Tax Abatement (If Available)

Many new developments used to come with 421-a tax abatements, which significantly reduce property taxes for the first 10–25 years of ownership. However, that program expired in 2022, and few new projects still offer it.

If the property you're considering does include a tax abatement, that can greatly affect your carrying costs and long-term affordability. Be sure to ask your agent to verify if one is in place and when it expires.

6. Construction Timelines Can Shift

If you’re buying in a building that’s still under construction, prepare for flexibility. Developers often provide estimated completion windows, but delays due to permitting, supply chains, or weather are common.

A good agent will stay in communication with the sponsor’s team and help manage expectations around when you'll actually be able to close and move in.

7. Know Your Rights: The Warranty

New developments in NYC come with a one-year warranty from the sponsor, covering defects in construction and materials. If you notice issues with appliances, flooring, windows, etc., you’re entitled to repairs—but there’s a deadline, and some sponsors are better than others at honoring their obligations.

You may also have a walk-through or “punch list” inspection before closing to note any issues.

8. Work With a Buyer’s Agent—It Costs You Nothing

Most new developments have in-house sales teams representing the developer. But you are entitled to bring your own buyer’s agent—someone who exclusively represents your interests.

The developer pays the commission, so there’s no cost to you, and your agent can help negotiate terms, coordinate inspections, review comparable units, and track deadlines.
