Understanding NYC Monthly Costs
The purchase price gets all the attention, but the number that decides whether an apartment is actually affordable is the monthly carrying cost — what you pay every month to live there on top of any mortgage. In New York that figure works differently depending on whether you're buying a co-op or a condo, and the two are not directly comparable on their face.
The mechanics matter because a lower price with a high monthly can cost you more over time than the reverse. Tracie Golding has helped buyers read these numbers since 1995, and the goal here is simple: to show how maintenance, common charges, property taxes, and assessments fit together so you can compare two apartments on what they truly cost to own.
Co-op maintenance: one bill that covers a lot
When you buy a co-op you don't own real property — you own shares in a corporation and a proprietary lease on your apartment. The monthly bill is called maintenance, and it bundles together the building's operating costs and your share of the property taxes into a single payment.
Because the property tax is already inside the maintenance figure, you won't get a separate tax bill the way a condo or house owner does. That's why a co-op maintenance number tends to look higher than a comparable condo's common charges — it's doing more work. Part of every maintenance payment is also tax-deductible: the portion that covers your share of the building's property taxes and any mortgage interest the building itself carries on its underlying loan. Your accountant can tell you the exact deductible percentage, which most co-ops report each year.
- —Covers building staff, heat, water, insurance, repairs, and reserves
- —Includes your share of the building's property taxes — no separate tax bill
- —Often includes interest on the building's underlying mortgage
- —A portion is typically tax-deductible (your accountant confirms the percentage)
Condo common charges plus a separate tax bill
A condo is real property — you own your apartment outright and hold a deed. The monthly common charges you pay to the condominium cover only the building's operating costs: staff, upkeep, shared utilities, insurance, and reserves. They do not include property taxes.
Instead, the city sends you a separate property-tax bill, billed quarterly or semi-annually depending on the assessed value. So a condo's true monthly cost is common charges plus the monthly equivalent of that tax bill — and that combined figure is the right thing to compare against a co-op's maintenance, not the common charges alone. Some new-construction and newer condos carry a tax abatement that lowers the tax bill for a set period; it's worth knowing whether an abatement applies and when it phases out, because the monthly cost will step up as it does.
- —Common charges cover building operations only — taxes are billed separately
- —Property tax comes as its own bill from the city, on a quarterly or semi-annual cycle
- —Compare a co-op's maintenance against condo common charges plus taxes, not common charges alone
- —Watch for tax abatements that lower the bill now but step up later
Assessments and what drives them
On top of the recurring monthly figure, both co-ops and condos can levy a special assessment — a temporary added charge to fund something the regular budget and reserves don't cover. It might run for a few months or a few years, and it can land whether you're a shareholder in a co-op or a unit owner in a condo.
Assessments aren't a red flag by themselves; well-run buildings use them responsibly. What matters is why one was levied and whether more are likely. A building with thin reserves and deferred work is far more likely to assess repeatedly than one that funds its reserves and plans ahead. Reading the building's financials before you commit is how you tell the difference, and it's part of the work Tracie does on every deal.
- —Capital projects: roof, facade, elevators, boiler, or window replacement
- —Local Law facade inspection and repair cycles
- —Low or depleted reserve funds that can't absorb a big expense
- —Shortfalls in the operating budget that the regular monthly charge doesn't cover
In plain answers.
Why is co-op maintenance higher than condo common charges?
Because they're not measuring the same thing. Co-op maintenance includes your share of the building's property taxes — and often interest on the building's underlying mortgage — inside one monthly figure. Condo common charges cover building operations only, with property taxes billed separately by the city. To compare fairly, add the condo's monthly tax equivalent to its common charges, then set that next to the co-op's maintenance.
How much of my monthly cost is tax-deductible?
For a co-op, the deductible portion is generally the part of maintenance that covers your share of the building's property taxes and the interest on the building's underlying loan — co-ops usually report that percentage each year. For a condo, the property taxes you pay directly are typically deductible, while common charges generally are not. Your accountant can confirm what applies to your situation, since deduction rules and limits change.
What is a special assessment and should it worry me?
A special assessment is a temporary added charge, beyond the regular monthly, that funds a specific cost the budget and reserves don't cover — often a capital project like a facade or elevator job. It isn't automatically a warning sign; responsible buildings use them. The questions to ask are why it was levied, how long it runs, and whether the building's reserves suggest more are coming.
How do I compare the true monthly cost of two apartments?
Put everything on the same basis. For a co-op, start with the maintenance figure. For a condo, add the common charges to the monthly equivalent of the property-tax bill. Then factor in any active tax abatement and when it ends, and check each building's financials for assessment risk. Comparing the headline price alone, or maintenance against common charges alone, will mislead you.
What is a tax abatement and how does it affect my monthly cost?
An abatement reduces the property tax on certain apartments for a defined period, which lowers the monthly carrying cost while it's in effect. The thing to understand is that abatements phase out, so the cost will rise over time as the abatement shrinks or ends. Knowing the schedule lets you plan for the higher number rather than being surprised by it.
