The building is the decision.

Buyers spend weeks judging an apartment and an afternoon judging the building. The risk sits the other way around.

You can renovate a kitchen, move a wall, or replace every window in your unit. You cannot change the building’s mortgage, its reserve fund, its boiler, or its board. Those are shared, they compound, and they arrive in your monthly charges whether you planned for them or not. In Manhattan, the average monthly maintenance on a co‑op sold in the second quarter rose 16 percent per square foot from a year earlier. The apartments did not change. The buildings did.

Why this issue is about the building

Issue 01 asked how long you intend to stay. Issue 02 asked what waiting costs. This issue asks the question that sits under both: what are you actually buying into?

In a co‑op you buy shares in a corporation that owns the building. In a condominium you own your unit outright but share the costs, the repairs, and the reputation of everything around it. Either way, you are taking on a long position in a building you did not choose for its finances.

Two buyers, one blind spot.

Both of these are real patterns I am seeing this season. Both people did their homework on the apartment. Neither had read the building.

The buyer who found the right apartment

She found a classic prewar two bedroom with good light, a fair price, and monthly maintenance below the neighborhood average. The low maintenance was the reason it worked on paper. It was low because the building’s underlying mortgage was locked at 3 percent in 2021 and comes due in two years. When it refinances at today’s rates, the building’s interest cost more than doubles, and every shareholder carries a share of it. The listing was accurate. It simply described the past.

The buyer whose lender said no

He was approved, he had a signed contract, and then his lender declined the building. The issue was not his credit. The building had a deferred facade repair it had not yet funded, and under Fannie Mae’s rules a building with unfunded repairs of more than $10,000 per unit due within the year is ineligible for the loans most lenders sell. He had to find a portfolio lender, at a higher rate, with weeks left on his commitment. The apartment had not changed. His cost of owning it had.

What is actually missing

Neither of them made a careless decision. What was missing was a way to read the building with the same care they gave the floor plan. The apartment comes with photographs, measurements, and comparable sales. The building comes with a financial statement most buyers never open.

They tell you what the building costs to run today. Its financials, its mortgage, its reserves, and its obligations under the law tell you what it will cost to run tomorrow. That second number is the one the next buyer will pay for.

The exhibit: same price, different building

Take two apartments that are identical on paper. Each is 1,000 square feet, each costs $1,500,000, and each carries $2,830 a month in maintenance today, the Manhattan co‑op average of $2.83 per square foot. The only difference is the building.

Building A has a long fixed mortgage, funded reserves, and its compliance work done. Its charges rise 3 percent a year. Building B has an underlying mortgage that resets, a Local Law 97 gap, and a capital plan it has not funded. Its charges rise 8 percent a year, half the most recent annual increase in the Manhattan average.

Over ten years, the owner in Building B pays $102,650 more in monthly charges than the owner in Building A. That is the visible cost. The larger one shows up when you sell.

A buyer in year ten with a fixed monthly budget can borrow about $284,000 less to buy in Building B than in Building A. That is roughly 19 percent of today’s price, coming off the value of an apartment that never changed. The building made that decision for you, on the day you chose it.

How I read a building

Four documents. As in the earlier issues, the order matters.

• The audited financial statements, three years of them. One year is a snapshot. Three years is a trend. I look for whether the building runs a surplus or a deficit, whether expenses are rising faster than income, and what the auditor’s notes say that the summary does not.
• The underlying mortgage, for co‑ops. The balance, the rate, and the maturity date. A low rate that matures soon is a future increase in your maintenance, already scheduled. A building that refinanced recently, or carries little debt, has already absorbed the cost.
• The reserve fund and the capital plan. Reserves are what the building has saved for the repairs it knows are coming. Fannie Mae expects a condominium budget to set aside at least 10 percent for replacement reserves, and it does not accept special assessments in place of that. Thin reserves and a long list of planned work usually mean an assessment is coming.
• The board minutes, twelve to twenty-four months. The minutes are where a building talks to itself. Facade inspections, boiler conversions, insurance renewals, sublet disputes, and the word “assessment” appear here months before they reach a shareholder’s bill.

Five questions before you make an offer

• One. When does the building’s mortgage mature, and at what rate is it carried today?
• Two. How large are the reserves, and what capital work is planned in the next five years?
• Three. Has the building filed its Local Law 97 report, and what will 2030 require of it?
• Four. Is there a current or planned assessment, and what is it for?
• Five. Will a mainstream lender finance this building, and has one done so recently?

If the answers are clear, the building is probably well run. If the answers are hard to get, that is an answer too.

For buyers

Read the building before you fall for the apartment. A slightly higher maintenance in a building with a recent refinance, funded reserves, and its energy work complete can be the cheaper apartment over any hold longer than a few years. A low maintenance in a building that has deferred everything is often a price you will pay later, with interest.

For sellers

Buyers and their attorneys are reading buildings more closely than they were five years ago, and lenders are reading them more closely still. If your building has done the work, say so, with documents, before the first showing. If it has not, price for what an informed buyer will find, because they will find it. A well run building is a selling point only when you can prove it.

What that sounds like in the room

It sounds like me asking for the financial statements before the second showing, not after the accepted offer. It sounds like telling a buyer that the apartment she loves is in a building I would want her to pass on, and showing her why on one page. It sounds like telling a seller that his board’s last three years of decisions are now part of his listing.

The line I am watching

Local Law 97’s second compliance period. From 2030, emissions limits for covered buildings tighten as the city moves toward a 40 percent cut in building emissions from 2005 levels. Penalties run up to $268 for every metric ton over the limit, every year. A building over 25,000 square feet that meets today’s limit may not meet 2030’s without capital work. The buildings planning for it now will look very different in five years from the buildings that are not.
