Buy first or sell first? Timing a downsizing move in New York

The trade-offs side by side

These are qualitative points, not statistics. Which order is faster, cheaper or more common depends on the market at the time and on your circumstances.

Selling first: what to plan for

The main advantage is certainty. Once your home is under contract, you know roughly what you can spend, and you will not be paying the carrying costs of two homes. The net proceeds guide shows which costs come out of the sale, including the state and city transfer taxes that sellers pay.

The main difficulty is the gap. If your sale closes before you can move into the next home, you need somewhere to live and somewhere to keep your belongings. The options are:

• A rent-back. You stay in the home you sold for an agreed period. It needs a written agreement covering the length of the stay, what you pay, who insures the home and what happens if you stay longer than agreed.
• A temporary rental. You rent a place for a short period. Leases have their own terms and dates, so you have to line them up with the closing date on the sale.
• Staying with family or friends, with storage for what does not fit.
• Negotiating a longer closing so the sale and the purchase close near each other.

None of these has a fixed timeline set by law, so write down dates in the contract and do not rely on a verbal understanding. A move manager can help with two moves and storage; see our resources page for move managers listed there.

Buying first: what to plan for

Buying first lets you take the time to find the right home and move once. The cost is that you carry two homes until the first sells. For a co-op or condo, that means maintenance or common charges on both. For a house, it means taxes, insurance and upkeep on both. You also depend on the sale for the money, which is where financing comes in.

Bridge financing, in general terms

A bridge loan or credit line borrows against the equity in your current home to pay for the next one before the sale closes. Terms, costs and eligibility vary by lender. What to raise with a lender before making an offer:

• Whether the loan is available on a co-op, a condo or a house. Lenders differ.
• What every fee is, when repayment is due and what happens if the sale is delayed.
• Whether you can qualify to carry both payments if the sale takes longer than planned.
• Whether the seller of the home you want will accept an offer that depends on financing you do not yet have.

A home equity line on your current home also has to be paid off at closing, so tell the attorney about it early.

Primary residence rules when you own two homes

The state and city property tax benefits described in our senior property tax exemptions guide attach to a primary residence. STAR's credit requires owning and living in the home on July 1, and the New York City co-op and condo abatement requires the buyer to have purchased by January 5 for the July 1 tax year. If you plan to own two homes at once, ask when each benefit starts and stops. A 2026 state budget measure also created a New York City surcharge on some homes that are not the owner's primary residence; the Mayor's office says it applies to owners who have a separate primary residence, per its notice to property owners. Ask a CPA whether it could touch a home you would hold for a while.

Co-op board approval and why it changes the timing

A co-op buyer purchases shares in a corporation, and the shares carry a proprietary lease. The owners are both shareholders and tenants of that corporation, and a board elected by shareholders runs it, per the Attorney General's co-op guidance and board directors booklet. The Attorney General's pages do not describe the approval steps. The board package, the interview and the financial requirements are set by each building, so ask for the proprietary lease, by-laws and house rules, and ask the managing agent or your attorney what the building requires and how long its process usually runs.

Why this matters if you are buying first

Whichever order you choose, a co-op purchase adds a step between signing the contract and closing. The approval decides whether the deal closes at all. Buying first therefore means you may hold a signed contract while you wait on the board and while you are still trying to sell. If the board says no, you can be left with a home to sell and no place to go. Selling first has its own board risk: your buyer, if you are in a co-op, needs approval before you can close, which moves your own date.

The 2026 New York City law

New York City adopted a law in 2026, known as Local Law 58 of 2026, that sets deadlines for co-op boards to respond to applications. Ask your attorney whether it applies to your building and which deadlines it sets.

Boards are generally not required to give reasons for a denial, so do not assume you will get one. New York City's Human Rights Law prohibits housing discrimination based on actual or perceived age and lawful source of income, among other classes. It covers co-op and condo board members, per the city's fair housing page. If you think a decision was discriminatory, the city's Commission on Human Rights takes complaints.

Condos

A condo works differently. A right of first refusal exists only if the condo's own documents provide it. Where a condo board has no approval right, the offering plan has to say so, per the Attorney General's regulation at 13 NYCRR 20.3. Ask for the declaration and by-laws before you assume either way. Our guide to buying a co-op or condo in New York City goes deeper.

Contingencies that connect the two deals

Contracts in New York are usually drafted by an attorney. In downstate New York, the seller's attorney prepares the contract, per the State Bar Association, and brokers cannot give legal advice on contract terms, per the Department of State's Legal Memorandum LI04. So the terms that link your sale and purchase are matters for your attorney. General categories to raise:

• A financing contingency, which lets a buyer out if a loan is not approved.
• A sale-of-home contingency, which makes your purchase depend on selling your current home. Sellers may not accept it, and it makes an offer less attractive to them.
• Board approval, for a co-op purchase, which is how the building's decision enters the contract.
• Closing dates that are close together or that can be extended, so one deal does not fall through because the other slips.

Timelines vary from deal to deal. Ask your attorney what the contract does if the other side slips, and whether a deposit is at risk.

Renting your home or a temporary place

If you buy first and want to rent out your old home while it is on the market, check your documents. In a co-op, the by-laws and proprietary lease set the sublet provisions. In a condo, the declaration and by-laws address rentals, per the Real Property Law's condominium act. A lender may also have terms on renting out a home. Renting can complicate the primary-residence questions above, so ask a CPA before you do it.

If you sell first and rent somewhere for a while, the lease dates become part of your plan. A rent-back and a temporary lease are alternatives, and a mix is possible, such as a short rent-back followed by a furnished rental. Get the terms in writing.

Tax rules that depend on the order

• Home-sale exclusion. IRC section 121 excludes up to $250,000 of gain, or $500,000 on a joint return, if you owned and used the home as your main home for at least 24 months in the five years before the sale. Renting the home for a long stretch before selling can affect the use test, so ask your CPA. See the IRS topic 701.
• Moving out of state before you sell. A nonresident seller must estimate New York tax on the gain with Form IT-2663 unless the property qualifies in total as a principal residence under section 121. See the IT-2663 instructions.
• Buyer-paid taxes on your next home. The state mansion tax is 1 percent of the price when a home costs $1,000,000 or more, and New York City has a supplemental tax at $2 million and above. The buyer pays both. Our net proceeds guide lists the rates, and the calculator models the seller side.

Questions to answer before you choose

• How much can you carry, in payments and upkeep, if both homes are yours for a while, and for how long?
• Can you qualify for the next home without the proceeds from this one?
• If you are buying a co-op, what does the board require, and what happens to your deposit if it says no?
• Where would you live and store your belongings if the sale closes first?
• Can a rent-back or a longer closing on the sale make the dates line up?
• Have you asked an attorney how the two contracts interact?

A Long Island move to a community with a homeowners association adds documents to read; the 55+ communities pages explain what to ask for.
