WHAT THEY DON'T TELL YOU
The Hidden Costs of Buying
a Condo in NYC
The listing price is maybe 60% of what you'll actually pay in the first five years. Here is the real accounting your broker, your lender, and your seller all hope you never see.
The Price Tag Is a Lie
You found a one-bedroom in a nice building. Listing price: $800,000. You've done the math. You've got the down payment. Your mortgage pre-approval came through. You think you know what this will cost.
You don't.
Here is what $800,000 actually costs over five years of ownership in New York City:
That's $383,500 more than the listing price. Nearly half the purchase price again, paid in costs nobody highlighted in the listing, the open house, or even most of the closing process.
Let's break down every cost, one by one, so you know exactly where the money goes.
Closing Costs Nobody Warned You About
On an $800,000 condo with 20% down and a $640,000 mortgage, here is what you'll write checks for at closing — on top of your down payment:
| Cost | Amount | Notes |
|---|---|---|
| NYC Transfer Tax | $8,000–$11,400 | 1% under $500K, 1.425% over. On new construction, the buyer often pays. |
| NYS Transfer Tax | $3,200 | 0.4% of purchase price. Technically seller's tax — but in new construction, it's often shifted to the buyer. |
| Mortgage Recording Tax | $11,520–$12,320 | 1.8% on loans under $500K, 1.925% on loans over $500K. This is the single biggest closing cost most buyers don't expect. |
| Attorney Fees | $3,000–$5,000 | Your attorney reviews the offering plan, bylaws, financials, and contract. Do not skip this. |
| Title Insurance | $3,000–$5,000 | Lender's policy is mandatory. Owner's policy is optional but strongly recommended. |
| Working Capital Fund | $1,200–$2,400 | 1–2 months of common charges, paid to the building at closing. |
| Mansion Tax | $0 | Starts at 1% on purchases over $1M. Graduated up to 3.9% over $25M. At $800K you're under the threshold — barely. |
| Bank Fees / Appraisal | $1,000–$2,000 | Application fee, appraisal, credit report, flood cert. |
| Total Closing Costs | $30,920–$41,320 | On top of your $160,000 down payment. |
That's right: on an $800,000 purchase, you need roughly $200,000 in cash — the $160,000 down payment plus $30,000–$41,000 in closing costs. Your broker showed you the listing price. The actual cash required to walk in the door is 25% of the purchase price.
Monthly Costs That Keep Rising
Your mortgage payment is fixed (assuming a fixed-rate loan). Everything else goes up. Every year. Without asking your permission.
Common Charges
The average NYC condo common charge runs $1.50 to $2.50 per square foot per month. For a 750-square-foot one-bedroom, that's $1,125 to $1,875/month — before property taxes.
Common charges cover building operations: staff salaries, insurance, utilities, elevator maintenance, management fees, and (in theory) contributions to the reserve fund. They rise 3–7% annually. That $1,200/month charge becomes $1,533/month in five years at 5% growth. Over 30 years, it more than quadruples.
Property Taxes
NYC property taxes on condos are complex — your unit is assessed as if it were a rental property, then adjusted by a series of caps and abatements. The effective rate varies wildly, but a typical $800,000 condo pays $6,000 to $12,000/year in property tax.
Assessment Increases Without Your Vote
In most NYC condos, the board can raise common charges without a vote of unit owners. The bylaws typically require only a board resolution. You'll get a notice. You won't get a vote. The increase takes effect regardless of your opinion on it.
If the building's insurance premium jumps 30% — and many NYC buildings saw exactly that in 2023–2025 — that cost flows directly into your common charges. If the super gets a raise. If elevator maintenance contracts go up. If the managing agent negotiates a fee increase for themselves. You pay.
The Special Assessment Bomb
If you remember only one thing from this page, remember this: at any time, for any capital project, the board can send you a bill for tens of thousands of dollars — and you cannot say no.
A special assessment is a one-time charge levied when the building needs to pay for something the reserve fund can't cover. There is no cap. There is no vote required in most buildings. There is no advance warning requirement under New York law.
The reason special assessments happen so frequently in NYC is simple: New York does not require buildings to maintain a minimum reserve fund. Florida does. California does. New York does not. Boards keep common charges low to make units attractive to buyers, the reserve stays empty, and when a capital expense hits, they assess every owner.
Here is how to protect yourself:
- Request the building's audited financial statements — look at the reserve fund balance relative to annual operating expenses
- Ask for a complete history of special assessments over the past 10 years
- Check DOB BIS for Local Law 11 facade filing status — "unsafe" findings mean mandatory repairs and likely assessments
- Read the board meeting minutes — capital projects under discussion today become assessments tomorrow
- Search NYSCEF for active litigation — lawsuits cost money, and that money comes from you

Insurance Gaps You Won't Discover Until the Flood
Your building has an insurance policy. You think you're covered. You're probably not — at least not the way you think.
The Master Policy vs. Your Unit
The building's master policy covers the structure — walls, roof, common areas, the building's liability. It does not cover your personal property, your interior improvements (that renovated kitchen, those custom closets), or your liability as a unit owner.
You need your own HO-6 unit owner's policy. Most cost $400–$1,200/year. Many first-time condo buyers don't know this policy exists until they have a claim.
Loss Assessment Coverage
This is the coverage most people have never heard of — and it's the one that matters most.
If the building suffers a loss that exceeds the master policy's coverage (or falls within its deductible), the board can assess each owner for their share of the shortfall. Loss assessment coverage on your HO-6 policy reimburses you for these assessments — typically up to $50,000.
Flood Insurance in Zone AE
If your building is in a FEMA flood zone (AE, VE, or X-shaded), and your unit is on a lower floor, you may need separate flood insurance. The building's master flood policy may not cover individual unit contents or improvements. NFIP flood policies for condos run $500–$3,000/year depending on zone, floor, and coverage amount.
Check your building's flood zone at FEMA's Flood Map Service Center. Buildings in waterfront areas of Lower Manhattan, Red Hook, the Rockaways, Coney Island, and parts of Staten Island are especially high-risk.
The Managing Agent Tax
Every dollar your building spends passes through the managing agent. And managing agents in New York operate with zero licensing requirements, zero public accountability, and zero performance benchmarks.
Management Fees
Managing agents charge $25 to $60 per unit per month. In a 100-unit building, that's $30,000–$72,000/year — paid from your common charges. You don't choose the agent. You don't approve the fee. The board does. And most boards don't competitively bid the management contract.
Contractor Markups
When your building needs repairs, the managing agent hires the contractor. Standard industry practice is a 20–40% markup on contractor invoices. A $10,000 plumbing job becomes $12,000–$14,000 after the management company's cut. This is legal. This is standard. This is your money.
No Competitive Bidding
New York does not require condo or co-op boards to competitively bid contractor work. The managing agent can hire their preferred vendors — the ones who give them the best markup — and there is no transparency requirement, no disclosure obligation, and no regulatory body to complain to.

Local Law 11: The Bill That Comes Every 5 Years
If your building is over 6 stories tall — and most NYC condos are — it's subject to Local Law 11 (the Facade Inspection & Safety Program, or FISP). Every five years, the building must hire a licensed engineer to inspect the entire facade. If the engineer finds unsafe conditions, the building must repair them immediately.
This isn't optional. It's city law. And it's one of the most expensive recurring costs in NYC condo ownership.
The inspection cycle is public information. You can look up any building on DOB BIS to see its facade filing status. If the building is approaching year 4 or 5 of its cycle, or has an "unsafe" or "SWARMP" finding from its last inspection, budget for a significant assessment.
What makes Local Law 11 particularly insidious is the conflict of interest built into the system. The engineer who inspects the facade is often hired by — or has a referral relationship with — the contractor who performs the repairs. The managing agent brokers the relationship. Nobody in this chain is accountable to you, and everybody in this chain profits from finding more work to do.
We've documented this pattern extensively in our issue tracker.
Resale Friction: Paying to Leave
You bought. You paid the closing costs. You paid the assessments. Now you want to sell. Surprise: it costs money to leave, too.
Transfer Taxes (Again)
When you sell, you pay NYC transfer tax (1–1.425%) and NYS transfer tax (0.4%) on the sale price. On an $850,000 sale: $11,900–$15,500 in transfer taxes alone.
Flip Tax (Co-ops)
Most co-ops charge a "flip tax" — a fee to the building when a unit changes hands. Typically 1–3% of the sale price. On an $850,000 sale, that's $8,500 to $25,500. In some buildings, it's a flat dollar amount per share. Either way, it's money that comes out of your proceeds.
Board Approval (Co-ops)
In a co-op, the board must approve the buyer. They can reject for any reason — or no reason at all. The process takes 30–90 days and involves a full financial disclosure package. If the board rejects your buyer, you start over. This isn't a cost in dollars, but it's a cost in time, uncertainty, and lost deals.
Broker Commission
Standard in NYC: 5–6% of sale price, split between buyer's and seller's agents. On $850,000: $42,500–$51,000. Some sellers negotiate lower rates, but the standard is persistent.
You put $200,000 in cash into this purchase. Five years later, you sell for $50,000 more than you paid. Your actual cash back: $167,600. You lost $32,400 in real terms — on a property that appreciated.

What Nobody Says Out Loud
The real estate industry in New York is built on opacity. Every participant in the transaction has an incentive to keep you focused on the listing price and away from the true cost of ownership.
- Your broker earns a commission based on the sale price. They have no incentive to show you the 5-year cost. Many don't even know it.
- Your lender underwrites your mortgage payment. They do not underwrite your ability to pay a $40,000 special assessment.
- The seller wants the highest price. Disclosing the building's assessment history or the managing agent's markup practices is not in their interest.
- The managing agent wants buildings with high transaction volume. Scaring buyers away from the building is bad for business.
- The board's attorney works for the board, not for you. The offering plan amendments, assessment disclosures, and financial statements are available if you know to ask for them — but nobody volunteers them.
This is why this site exists. Not to discourage you from buying a condo in New York — for many people, it's the right decision. But to ensure you make that decision with full information, not the curated version the industry prefers.
How to Protect Yourself
You can't eliminate these costs. But you can see them coming.
Run the 5-year numbers before you make an offer
Use our True Cost Calculator to model the complete cost of ownership, including rising common charges, property taxes, and at least one assessment.
Read the offering plan — especially the tax abatement schedule
If the building has a 421-a or other abatement, know when it expires and what your tax bill becomes after. See Offering Plan Red Flags.
Request 5 years of financial statements and assessment history
A building with a healthy reserve fund (25%+ of annual budget) is far less likely to assess you. Multiple assessments in 5 years is a red flag.
Look up the building on CondosCoopsNYC
Our Building Reports aggregate DOB violations, HPD complaints, managing agent data, and litigation — everything you need in one place.
Research the managing agent
Check our Managing Agent Database. Some agents have patterns of high assessments, poor responsiveness, and contractor favoritism across their entire portfolio.
Buy adequate insurance from day one
Get an HO-6 policy with loss assessment coverage ($50,000 minimum). Add flood insurance if you're in a flood zone. This costs $1,000–$2,000/year and can save you $50,000+.
Keep a reserve of your own
Financial advisors say 3–6 months of expenses. For NYC condo owners, keep at least $20,000–$30,000 liquid beyond your emergency fund — specifically for assessments.
Frequently Asked Questions
Is it cheaper to buy a co-op instead of a condo?
Co-ops generally have lower purchase prices and no mortgage recording tax (because you're buying shares, not real property). However, co-op maintenance fees are typically higher because they include the building's underlying mortgage and property taxes. Co-ops also charge flip taxes on resale and require board approval, which adds friction and uncertainty. Run the 5-year numbers on both.
Can I deduct any of these costs on my taxes?
Mortgage interest and property taxes are deductible if you itemize (subject to SALT cap of $10,000). Common charges, special assessments, and insurance are generally not deductible for a primary residence. If you rent the unit out, most ownership costs become deductible as business expenses. Consult a tax professional.
How do I find out the reserve fund balance before buying?
Request the building's most recent audited financial statements through your attorney or the managing agent. The balance sheet will show the reserve fund balance. Compare it to the annual operating budget — a healthy reserve is 25–50% of the annual budget. Below 10% means an assessment is likely coming.
What if I can't afford a special assessment?
Some buildings offer payment plans, but they're not required to. You can try to negotiate with the board. If you can't pay, the building can place a lien on your unit, charge late fees and interest, and ultimately foreclose. Some owners take home equity loans or personal loans to pay assessments. This is why keeping a cash reserve is critical.
Are new construction condos safer from hidden costs?
New construction avoids some near-term capital expenses (the roof is new, the elevators are new), but introduces others: developer-set common charges that often spike after the offering plan period, 421-a tax abatements that expire and triple your taxes, and sponsor-controlled boards that may not act in owners' interests. New isn't automatically safer — it's differently risky.
