*By John G Slattery, The Upper East Side Guy*

Buying your first home in Manhattan is thrilling. It is also a bit like walking a new puppy down Madison Avenue: adorable, but full of surprises. After nearly four decades here, I have watched smart buyers trip over the same handful of things. Let's make sure you are not one of them.

## 1\. Forgetting That the Price Is Not the Price

That listing price is the headline, not the whole story. Closing costs add a meaningful percentage on top, so budget for them from day one.

## 2\. Not Knowing Your Closing Costs, Line by Line

Here are the big ones buyers should know:

- **The Mansion Tax.** Paid by the buyer on purchases of $1 million and up, with the rate climbing at higher prices.
- **Mortgage Recording Tax.** Applies to financed condos and townhouses. Co-op buyers are spared, since they buy shares, not real property.
- **The Flip Tax.** A transfer fee many co-ops, and some condos, charge on a sale. Usually the seller pays, but some buildings or contracts shift it to the buyer, so ask early.
- **Attorney Fees, Title Insurance, and Bank Fees.** Title insurance applies to condos and townhouses; co-ops use a lien search instead. Add in your lender's appraisal and origination fees.
- **Move-in Deposits and Adjustments.** Buildings may require a refundable move-in deposit, and you will reimburse the seller for any maintenance or common charges they prepaid.

## 3\. Leaving Money on the Table in Negotiations

Price is not the only lever. A few ideas:

- **Ask for a seller credit** toward closing costs instead of a straight price cut. Note that some co-op boards and lenders limit or scrutinize credits, so check first.
- **Ask what's included.** Before you sign, ask that items like custom built-ins, window treatments, or appliances stay with the apartment as part of the price, rather than paying extra or replacing them yourself later.
- **Negotiate who pays the flip tax** if the market or the building rules allow it.
- **Offer flexibility on timing.** A seller who needs a quick close, or a long one, may reward you for accommodating them.

Always run these strategies past your real estate attorney, because how a deal is structured matters for taxes and for your lender.

## 4\. Underestimating the Co-op Board Package

Think of the board package as the Westminster Dog Show for your finances: every detail gets inspected, and nobody wins on charm alone. Tax returns, bank statements, reference letters, the works. First-timers often wait too long to start gathering documents. Begin early, be thorough, and be honest.

**Plan for a bigger down payment.** On the Upper East Side, co-op down payments tend to run high. Some co-ops allow as little as 25% down, but 40% to 50% is more typical. Condos are usually more flexible, with down payments as low as 10%. Know the building's minimum before you start shopping.

**Know your post-closing liquidity.** Most co-ops want to see a cushion of liquid assets left after closing, often one to two years of maintenance and mortgage payments, and more in selective buildings. Retirement accounts may not count fully. Ask before you offer.

**What can go wrong, and how to be ready:**

- **The board says no.** Boards generally don't have to explain why. A polished package and interview are your best defense.
- **Your financing wobbles.** New jobs, new credit, or big purchases can unsettle your loan. Keep your finances boring until closing.
- **The appraisal comes in low.** If the bank values the apartment below your price, you may need to bring more cash or renegotiate.
- **Surprises in the building.** An upcoming assessment or major repair can raise your monthly costs right after you move in.
- **Your contract deposit is at risk.** Know your contingencies. In many New York deals, walking away without a valid reason can cost you your deposit, typically 10% of the price.

## 5\. Ignoring the Building's Financials

A gorgeous lobby can hide an underfunded reserve or an upcoming assessment. Have your attorney review the financial statements, board minutes, and any planned capital projects before you sign.

**Ask about Local Law 97.** New York's emissions law caps carbon output for most buildings over 25,000 square feet, with stricter limits from 2030 and steep fines for missing them. Upgrade costs can land in your maintenance or an assessment. Ask whether the building complies and how it plans to pay.

## 6\. Getting Pre-Qualified Instead of Pre-Approved

Pre-qualification is a friendly chat. Pre-approval is a lender actually reviewing your finances. In a competitive Manhattan deal, sellers want to see the second one.

**Just as important: be completely honest with your agent.** I see this all the time, even with buyers I have a terrific relationship with: they hold something back, hoping it will get them a better price. It won't. The more we know about your finances, budget, and timeline, the better we can negotiate and get in front of problems. A surprise that surfaces late, in front of a board or a bank, can cost you the apartment.

## 7\. Forgetting About Monthly Carrying Costs

Maintenance, common charges, real estate taxes, and insurance add up. A lower price with higher monthlies can cost you more over time than you think.

## 8\. Skipping the House Rules: Pets, Subletting and Pieds-à-Terre

You did not think I would write a whole post without mentioning dogs, did you? Some buildings limit size, breed, or number of pets. Confirm the policy in writing before your heart, and your Labrador, get attached.

Thinking you'll rent the place out down the road? Not so fast. Upper East Side co-ops in particular tend to frown on subletting. Many limit it, charge fees, or ban it outright. If flexibility matters, read the policy carefully or consider a condo.

Planning to use the apartment as a pied-à-terre? Check whether the building allows it, then know the new math. New York's pied-à-terre tax, an annual surcharge on non-primary residences valued at $1 million and up, took effect July 1, 2026\. The rate climbs with the property's value and applies every year you own it, on top of regular property taxes. Talk to your accountant before you buy.

The courts have weighed in, too. On November 4, 2026, a unanimous four-judge panel of the state Appellate Division, Second Department, dismissed a challenge to the tax's rollout, letting the city move ahead with collecting it. Other challenges remain, so watch this space.

## 9\. Shopping Without a Local Expert

Every building has its personality, its board quirks, and its unwritten rules. An agent who knows the neighborhood can save you time, money, and a few gray hairs.

## 10\. Waiting for the "Perfect" Moment

There is no perfect market, just a well-prepared buyer. Know your numbers, know your must-haves, and be ready to move when the right home appears.

## The Bottom Line

Your first home should feel like a victory lap around the Reservoir, not a sprint through a minefield. If you are thinking about buying on the Upper East Side, or anywhere in Manhattan or Brooklyn, I would love to help.
