NYC Affordability

The structural difference behind every cost difference

A co-op purchase is a share purchase in a corporation, governed by a proprietary lease. A condo purchase is real property, recorded like a house. That single distinction — personal property vs. real property — is the root cause of almost every cost difference between them: what taxes apply, what a lender requires, what a board can demand, and what happens when you sell.

Where condos cost more: taxes on the way in

Because a condo is real property, it’s subject to NYC/NYS mortgage recording tax on financed purchases — roughly 1.80% on loans under $500,000 and 1.925% on loans of $500,000 or more. Co-ops, as personal property, are exempt from this tax entirely; it simply doesn’t apply.

On an $800,000 purchase with 20% down (a $640,000 loan), that’s $12,320 in mortgage recording tax a condo buyer pays that a co-op buyer for the identical price never sees. Condo buyers also generally face higher overall closing costs — typically 2.5%–5%+ of price for a financed resale condo, versus a more modest, mostly-flat set of fees (attorney, bank attorney, application/board fee, move-in deposit) that commonly total somewhere in the $6,000–$10,000 range for a co-op at the same price point, largely because there’s no title insurance or mortgage recording tax to factor in.

Where co-ops cost more: the back end and the buffer

Co-ops make up for the cheaper closing in two ways condos mostly avoid:

Reserve requirements. Co-op boards typically require 12 months of post-closing liquid reserves (24+ at conservative buildings) — cash that has to sit, uninvested in the deal, on top of the down payment. Condo lenders don’t usually impose an equivalent post-closing liquidity requirement. See our co-op board reserve guide for the full math on what counts as liquid and how much this actually adds up to.

Flip tax at resale. Most NYC co-ops charge a flip tax when you sell — typically 1% to 3% of the sale price, seller-paid, set independently by each building’s proprietary lease. On an $800,000 sale, a 2% flip tax (roughly the citywide average) is $16,000 coming off the seller’s proceeds. Condos generally don’t carry an equivalent fee, though some newer condo buildings do charge a comparable “reserve fund contribution” at resale — it’s less common and usually smaller, but worth checking a specific building’s rules before assuming condos are flip-tax-free across the board.

Where condos are easier: qualifying

This is the difference buyers feel earliest, not just at closing. Condo lenders typically underwrite to a back-end debt-to-income ceiling around 43% (conventional conforming), sometimes with a more conservative 36% target. Co-op boards, by contrast, typically cap DTI at 28% — meaningfully stricter, on top of the separate reserve requirement boards also impose. At an identical purchase price, a buyer often needs noticeably less income to qualify for a condo than for a co-op, purely because of which DTI ceiling applies. See our income-needed-to-buy guide for exactly what that gap looks like in dollars.

Condos also generally allow more flexibility to sublet, rent out, or sell to buyers a board might reject outright — co-op boards can deny a sale without stating a reason, a level of discretion condo boards (which typically hold only a right of first refusal, not full financial vetting) don’t have.

What’s the same either way

The mansion tax — 1% to 3.9% of price on residential purchases of $1,000,000 or more — applies identically to co-ops and condos; it’s a state tax tied to price, not property type, so it isn’t a factor in choosing between them. PMI, if you’re putting down less than 20%, is also modeled the same way on both sides. The real differentiators are the ones above: mortgage recording tax, reserve requirements, DTI ceilings, and flip tax.

The bottom line

Neither is categorically cheaper — it depends which side of the transaction and which point in the timeline you’re weighing. A co-op is usually the lower-cost way in and the higher-cost way out; a condo is the more expensive way in but carries less friction getting approved and getting out. If you’re planning to hold for a long time and can clear a board’s stricter DTI and reserve bar, a co-op’s lower upfront tax burden compounds in your favor. If you expect to sell within a few years, move for work, or want maximum flexibility on subletting, a condo’s higher entry tax is often the cheaper total cost once you account for a co-op’s flip tax and reserve drag.
