Buying on Billionaires’ Row can feel like picking stocks during a volatile market. You want the view, the address, and a smart return, but sponsor units and resales follow very different rules. In this guide, you’ll see how costs, liquidity, and risk stack up in Midtown’s ultra-luxury towers, plus a simple closing-cost example you can run yourself. Let’s dive in.
Sponsor units vs. resales: what they mean
Sponsor units are developer-owned condos or co-ops that have not been sold to a third party. They are offered under an Attorney General–filed offering plan with specific disclosures and amendments you should review in the state’s offering plan database.
Resales are sales by existing owners. They follow standard disclosure rules rather than the sponsor’s offering plan.
Midtown market context: why it matters now
Midtown’s ultra-luxury corridor is not one-size-fits-all. Contract activity picked up in early 2025 after a volatile stretch, with compressed inventory at some price bands and uneven absorption in others, per recent reporting on Manhattan’s normalization trend (Crain’s New York).
Case studies show the split-screen dynamic. Coverage in late 2023 highlighted deep discounts and slow resales in several 57th Street supertalls when inventory overhangs met soft demand (Curbed). By spring 2025, marquee sponsor deals at Central Park Tower were topping weekly luxury charts again as pricing and demand aligned for specific trophy units (The Real Deal).

Closing costs: who pays what
Here is the practical difference many investors underestimate.
- In a typical resale, the seller usually pays New York City and New York State transfer taxes. The buyer pays the state’s mansion tax if the price is $1 million or more. See official guidance for the NYC Real Property Transfer Tax (NYC Department of Finance) and state transfer and mansion tax rules (New York State Tax).
- In many sponsor sales, the buyer is contractually responsible for the sponsor’s transfer taxes and various sponsor charges unless you negotiate otherwise. That increases your effective entry price.
A simple $2,000,000 example
Assume a Midtown condo at $2,000,000. Illustrative only. Always confirm current rates and who pays in your contract.
- Mansion tax: 1.25% at $2,000,000 = $25,000 (buyer in both scenarios). See state rules above.
- NYC transfer tax: 1.425% at $2,000,000 = $28,500.
- NY State transfer tax: 0.4% at $2,000,000 = $8,000.
Resale scenario: you pay the $25,000 mansion tax; the seller typically pays the $28,500 NYC and $8,000 NYS transfer taxes.
Sponsor scenario: you pay the $25,000 mansion tax and are often asked to pay the seller’s $28,500 NYC and $8,000 NYS transfer taxes, plus sponsor attorney and working-capital or move-in contributions stated in the offering plan. The extra transfer taxes alone add $36,500 to your effective cost, before any sponsor fees.
Pros and cons for Midtown investors
When a sponsor unit can make sense
- You plan a long hold and want new finishes, modern systems, and potential sponsor concessions when inventory is heavy.
- You can negotiate closing credits or upgrades that offset the higher transfer-tax burden.
- Your tax planning includes a like-kind exchange strategy for investment property. Review 1031 basics first (PropertyClub overview).
- You value early entry into a building with limited future supply on prime park-adjacent blocks.
When a resale can be the better fit
- You want clearer comps, established common charges, and predictable underwriting.
- You need immediate rental income and prefer a stabilized building with a resale track record.
- You want lower buyer-side closing costs, since sellers typically cover transfer taxes in resales.
Financing, liquidity and rent math
- Lenders often underwrite established condos more smoothly than active new developments. Some new projects require specific loan-to-value and project-level approvals. Discuss lender policies before you sign a contract (WHFIRM overview).
- Buildings with heavy unsold sponsor inventory can pressure resale pricing if the sponsor discounts to move units. Once absorption stabilizes, liquidity often improves.
- Luxury rental yields in Manhattan are usually low on a percentage basis, so underwrite net yield after common charges, taxes, management and vacancy. Industry commentary places many Manhattan condo yields in the low to mid single digits (market overview).
Co-op and condo rules for investors
- Co-ops often limit subletting and can deny buyers. That reduces flexibility for pure investment strategies. See board and rule context in trade guidance (CooperatorNews).
- Condos are generally more flexible for rentals but still follow building bylaws and house rules. Always confirm rental and minimum-lease terms in writing.
Your due diligence checklist
Use this as a starting point with your attorney and lender.
- Review the full offering plan and all amendments for sponsor units. Confirm unsold inventory, reserves, closing fees and any rental limits. Use the state offering plan database.
- Model transfer-tax allocation under multiple scenarios. Plug in NYC RPTT and NYS transfer and mansion tax schedules to see your true effective price (NYC RPTT, NYS transfer and mansion tax).
- Check assignment rights in new-development contracts. If pre-closing resale is important, you need explicit permission and terms in the contract (assignment overview).
- Study building comps and absorption history. Look at price per square foot, days on market and resale velocity alongside current sponsor listings. Trade coverage can provide color on Midtown contract leaders and pricing shifts (The Real Deal example).
- Confirm sublet policy and investor ratios. For co-ops, review the proprietary lease; for condos, review the declaration and house rules (CooperatorNews guide).
- Verify lender policies for the specific building. Ask about down payment minimums, project approval and concentration of sponsor inventory (WHFIRM overview).
Midtown case snapshots
- Discounts and slow resales: Reporting in 2023 showed price cuts and sluggish absorption in several 57th Street supertalls when supply was high and buyers were selective (Curbed).
- Rebound contracts: By March 2025, Central Park Tower led weekly luxury contracts again, showing how pricing and timing can flip outcomes for specific sponsor units (The Real Deal).
Bottom line
On Billionaires’ Row, you are not buying the market. You are buying a building, a stack line, and a contract. Sponsor units can deliver new-product appeal, negotiated value and long-hold potential, but they often carry higher buyer-side closing costs and assignment limits. Resales offer clearer comps and usually lower buyer closing costs, but liquidity can still be thin in trophy price bands.
