On a $1.5 million new construction condo in New York City, the sponsor's contract typically assigns the buyer $27,375 in transfer taxes that a resale buyer never sees: 1.425% to the city and 0.4% to the state, both of which the seller pays in an ordinary resale. That clause lives in the offering plan, not in the listing, and it is the single largest structural difference between buying new and buying used in this city.
Add the sponsor's attorney fee, the working capital contribution, and the resident manager's unit share, and the same headline number costs a new development buyer roughly two percentage points more to close than a resale at the identical price. My sales practice runs across Manhattan, Brooklyn, and Queens, covering resales, new construction, and buy-side work, and this is the arithmetic I put in front of a client before they walk a model unit, not after.
None of this is an argument against new construction. It is an argument for pricing it honestly. Below is what each side actually costs, which sponsor line items move under pressure, and where the real risk sits in a pre-construction contract.
The Two Cost Structures Side by Side
Buyers tend to compare new development to resale on price per square foot and finishes. The closing statement is where the two diverge. Mansion tax, your own attorney, title insurance, and mortgage recording tax land on you either way. Four line items do not.
| Closing line item | Resale buyer | New development buyer |
|---|---|---|
| NYC transfer tax (1.425% over $500,000) | Seller pays | Buyer pays, per most offering plans |
| NYS transfer tax (0.4%) | Seller pays | Buyer pays, per most offering plans |
| Seller's attorney fee | Seller pays | Buyer pays the sponsor's fee, commonly $2,000 to $5,000 |
| Working capital contribution | None | Typically one to two months of common charges |
| Resident manager's unit share | None | Pro rata share, amount fixed in Schedule A |
| Mansion tax (1% at $1M, tiered above) | Buyer pays | Buyer pays |
| Own attorney, title, mortgage costs | Buyer pays | Buyer pays |
Rates per the NYC Real Property Transfer Tax and NYS Real Estate Transfer Tax schedules. Sponsor-specific amounts vary by offering plan.
That top block is why financed new development purchases commonly run 4% to 6% of the price in buyer closing costs while a comparable financed resale lands closer to 2% to 4%.

The Sponsor Line Items a Resale Buyer Never Pays
Transfer taxes shifted to the buyer
This is the big one. In a private resale the seller writes both transfer tax checks. In a sponsor sale the offering plan almost always reverses that, and the buyer absorbs the city tax and the state tax on top of the mansion tax the buyer already owes. The reversal is legal, it is disclosed, and most buyers still find it in the contract rider rather than in the sales gallery conversation.
One detail worth knowing before your attorney explains it: under New York Tax Law section 1404, amended effective July 1, 2021, when the buyer pays the state transfer tax on a conveyance of residential real property, that tax amount is excluded from the taxable consideration. Before that amendment the figure was added back in and taxed again. Ask your attorney to confirm the exact taxable consideration used on your closing statement, because the offering plan tells you who owes the tax, not what the final calculation nets to.
The sponsor's attorney fee
You pay your own attorney, and in a sponsor sale you pay the developer's attorney too. Budget $2,000 to $5,000 depending on the building and the firm. In a resale that number is zero to you.
Working capital contribution
New condominiums start with an empty bank account, so each closing funds it. The standard structure is a contribution to the working capital fund equal to one month of the unit's common charges, plus a matching contribution to the reserve fund. Some plans ask for more. It is a real cost, it is non-refundable, and it does not build equity.
Resident manager's unit share
In larger buildings the condominium buys an apartment for the live-in superintendent, and each purchaser pays a pro rata share of that purchase toward the board. The exact dollar figure for your unit is printed in Schedule A of the offering plan. It is not a rounding error in a big building, and it is the line item buyers most often discover at the closing table.
Where these numbers live
Every sponsor cost above is disclosed in the offering plan filed with the New York State Attorney General, usually in the Purchaser's Closing Costs section and Schedule A. Nothing here is hidden. It is just buried in a document most buyers skim. My guide to reading a condo offering plan covers which sections to open first.
Worked Example: $1.5 Million, Both Ways
The figures below are illustrative, built on a hypothetical $1.5 million condo with $1,500 in monthly common charges. They isolate only the costs that differ between the two purchase types. Your own numbers depend on the specific offering plan, your financing, and your attorney's review.
| Illustrative cost at $1,500,000 | Resale buyer | New development buyer |
|---|---|---|
| NYC transfer tax at 1.425% | $0 | $21,375 |
| NYS transfer tax at 0.4% | $0 | $6,000 |
| Sponsor's attorney fee | $0 | $3,000 |
| Working capital and reserve contribution | $0 | $3,000 |
| Mansion tax at 1% | $15,000 | $15,000 |
| Difference attributable to buying new | Baseline | About $33,375 |
Illustrative only. Excludes the resident manager's unit share, which varies by building, and all costs common to both transaction types.
Roughly $33,000 on a $1.5 million contract is about 2.2% of the price. Put another way, a new development asking $1,500,000 and a resale asking $1,467,000 cost you about the same amount of cash to close. That is the comparison to run, and almost nobody runs it.

Which Sponsor Line Items Actually Move
Sponsor closing costs are negotiable, but not evenly, and not at every stage of a sellout. The pattern is consistent enough to plan around.
Moves more often
- • Who pays the two transfer taxes, in whole or in part
- • The sponsor's attorney fee
- • A credit against common charges for a fixed period
- • Storage, bike room, or parking bundled at closing
Moves rarely
- • The headline purchase price
- • Working capital and reserve contributions
- • The resident manager's unit share
- • Anything on day one of a new offering
The reason the price is the last thing to move is structural, not stubbornness. Recorded sale prices become the comps for every unit still unsold in the same building, and they feed the release prices a construction lender agreed to. A closing cost credit costs the sponsor the same cash and leaves the recorded price intact. Understanding that is what lets you ask for the right concession instead of the one that gets refused.
Your bargaining position also arrives on a schedule. A sponsor with 85% of a building sold and a handful of odd-line units left has a very different answer than the same sponsor in the opening month. If a unit has been sitting through a full season, ask for the transfer taxes. This is the same dynamic that governs pricing on sponsor units in older co-op and condo buildings, where the seller is also an entity with an inventory problem rather than a family with a moving date.
Deposit Structure and Timeline Risk
Cost is only half the comparison. The other half is when your money is committed and for how long.
In a resale you sign, deposit 10%, and close in roughly 60 to 90 days. In a pre-construction sale you sign, deposit 10% or more into an escrow account governed by the offering plan, and then wait for a projected closing date that the sponsor is permitted to move. Delivery on a building under construction depends on a temporary certificate of occupancy for your unit's line, and construction schedules slip.
The practical exposure for a financed buyer is the mortgage commitment. Commitments run a limited number of days. If your closing slides past that window, you re-apply, the lender re-underwrites, and your rate is whatever the market offers on the new lock, not what it offered when you signed. Buyers focus on the deposit sitting in escrow. The commitment expiry is the part that actually changes the deal.
Have your attorney price the delay
Before signing a pre-construction contract, ask your real estate attorney three questions in writing: what is the outside date beyond which I can cancel and recover my deposit, what happens to my deposit if the sponsor misses it, and which amendments to the offering plan give me a right to rescind. I maintain a list of real estate attorneys clients can choose from. Tax treatment questions belong with your CPA.
What the Resale Side Gives You Instead
Resale is not just the cheaper closing. It is the more knowable purchase.
A resale condo or co-op has audited financial statements, an actual reserve fund balance, a real history of common charges and assessments, and minutes you can read. A new building has projected budgets in Schedule B of the offering plan, and projections are estimates. First-year common charges in a new condominium sometimes rise once the building is fully occupied and the sponsor's budget meets real operating costs.
Resale also gives you a seller who can be negotiated with directly, occupancy on a date you can plan around, and the ability to see the finished apartment in the light it actually gets. What you give up is the new systems, the amenity package, the warranty on new construction, and in many cases the tax abatement.
Where the Tax Abatement Changes the Math
Many new condominiums carry a property tax exemption that materially lowers the monthly carrying cost for a set number of years. That benefit is real and it belongs in the comparison, but it is a temporary line, not a permanent one, and it phases out on a published schedule. A monthly payment built on the abated tax figure is not the monthly payment you will have in year twelve.
The current program for new construction is 485-x, the Affordable Neighborhoods for New Yorkers exemption enacted in April 2024 as the successor to 421-a, with benefit terms running as long as 35 to 40 years depending on the project. Buildings completed under earlier program versions carry earlier schedules. I break down the phase-in and phase-out mechanics in the 421-a tax abatement guide. Before comparing a new development's monthly cost to a resale's, ask which program the building is under, which year of the benefit it is in, and what the unabated tax bill looks like.
How I Would Decide Between the Two
Run three numbers, in this order.
First, total cash to close on both, not asking price. The gap is usually around two percentage points of the price, and it is the correct adjustment to make before you say one is more expensive than the other.
Second, the fully unabated monthly carrying cost on the new development, so you are comparing the same year of ownership on both sides.
Third, your own tolerance for a moving closing date. If your lease ends on a fixed day or your rate assumption is tight, a projected closing date is a risk you are underwriting personally, and no concession compensates for it.
New construction wins on systems, layout efficiency, amenities, and the abatement window. Resale wins on transaction cost, financial transparency, and certainty of timing. Neither is the right answer in the abstract. The right answer is whichever one survives the three numbers above once the offering plan is on the table.
