What Is the Difference Between a Condo and a Co-op?

When you buy a condominium in New York, you own the unit as real property. When you buy a cooperative, you do not receive a deed to the apartment itself. Instead, you purchase shares in a corporation that owns the building, and those shares come with a proprietary lease giving you the right to occupy a specific unit. This ownership difference affects financing, taxes, board approval, subletting rules, and your ability to sell. In Manhattan, where both condos and co-ops are common ownership options, understanding these differences is essential before making an offer.

What Do You Actually Own in a Condo vs. Co-op?

In a condominium, you own your individual unit as real property under New York Real Property Law Article 9-B. In most residential condo purchases, the buyer receives a deed, and the owner’s name appears on the property records. You also own an interest in the building’s common elements, which may include hallways, lobbies, elevators, and the roof, depending on the building’s declaration.

In a cooperative, the building is owned by a corporation. When you buy a co-op, you purchase shares in that corporation. Those shares are allocated to a specific apartment and typically reflect factors such as the unit’s size, location, or value within the building. Along with those shares, you receive a proprietary lease, which is a long-term lease that gives you the right to occupy your specific apartment.

This distinction has real legal consequences. A condo owner holds title to real property and can mortgage, sell, or transfer the unit like any other piece of real estate. A co-op shareholder holds personal property (stock) and occupies the unit under a lease, not a deed. That means co-op transactions are governed by different legal rules, and they require different documentation at closing.

Key Takeaway: Condo buyers own real property and receive a deed. Co-op buyers own shares in a corporation and receive a proprietary lease. This ownership difference drives nearly every other distinction between the two.

How Does the Board Approval Process Work?

One of the most significant practical differences between condos and co-ops in Manhattan is the board review process. Condo purchases usually do not involve the same discretionary board approval process used in co-op transactions. A condominium’s declaration or bylaws may give the board a right of first refusal, which gives the association a limited opportunity to purchase the unit on the same terms offered by the buyer. In practice, condo buyers usually face fewer approval barriers than co-op buyers, but the building’s governing documents still control the exact process.

Co-op purchases are different. Many Manhattan co-ops require prospective buyers to submit a detailed application package to the co-op board of directors. This package typically includes:

• Two to three years of federal tax returns
• Bank and investment account statements
• Employment verification and salary information
• Personal and professional reference letters
• A completed financial statement
• The signed purchase agreement and loan commitment letter

After reviewing the package, the board may schedule an interview with the buyer. The interview may cover your financial background, your reasons for purchasing, how you plan to use the apartment, and whether you intend to sublet.

The board then decides whether to approve or reject the application. Co-op boards generally have broad discretion when reviewing purchasers, and many boards do not provide a reason for rejection. New York courts generally defer to good-faith decisions made by residential cooperative boards when the board acts within its authority and for the purposes of the cooperative. That discretion is not unlimited. A board may not reject a buyer for a discriminatory reason or otherwise act in bad faith, outside its authority, or in violation of applicable law. 

For covered New York City co-ops, Local Law 58 of 2026 adds timing rules for applications made on or after July 28, 2026. Covered co-ops must acknowledge application materials within 15 days and must provide a decision within 45 days after a complete application is acknowledged or deemed complete, subject to limited extensions and summer recess tolling.

Key Takeaway: Co-op boards in Manhattan generally have wide discretion to approve or reject buyers, although that discretion is not unlimited. Beginning July 28, 2026, covered NYC co-ops must also follow statutory timelines for acknowledging and deciding purchase applications. Condo purchases usually involve fewer approval barriers, but the building’s governing documents still control the process.

Peter Zinkovetsky can help buyers prepare co-op board application packages and review issues that may affect how their financial profile is presented.

How Do Down Payments and Financing Differ?

Down payment requirements are another major difference, but the exact amount depends on the lender, building, buyer profile, and type of transaction. Condo buyers often have more financing flexibility because the unit is real property and the lender can take a mortgage lien against the unit. Some condo transactions may allow lower down payments than many co-op transactions, but buyers should confirm the building’s rules and lender requirements before relying on a specific percentage.

Co-op down payment requirements are often higher because the buyer must satisfy both lender requirements and the co-op board’s financial review. Many co-op boards look closely at liquidity, debt, income, and post-closing reserves before approving a buyer. Some buildings also impose financing limits or require all-cash purchases. Buyers should review the building’s financial requirements before making an offer.

What Is a Co-op Share Loan?

Because a co-op buyer does not own real property, a traditional mortgage does not apply. Instead, co-op buyers obtain a “share loan” (sometimes called a “co-op loan”). In a share loan, the lender’s collateral is the borrower’s shares in the co-op corporation and the proprietary lease, not a piece of real property. This means fewer lenders offer co-op share loans compared to conventional mortgages, and interest rates may differ slightly.

One additional factor may affect co-op financing: the building’s underlying mortgage. Many co-op buildings carry a blanket mortgage on the property. If the building has one, each shareholder’s maintenance may include a proportional share of the building’s debt service. Lenders evaluating a co-op share loan may consider the building’s overall financial health, including any underlying mortgage, the reserve fund, and the percentage of units that are investor-owned or sponsor-held.

Key Takeaway: Condo buyers often have more financing flexibility because the unit is real property. Co-op buyers usually face stricter building and lender requirements and must use a share loan rather than a traditional mortgage. The building’s underlying mortgage can also affect the buyer’s financial review.

How Do Costs Compare: Purchase Price and Monthly Fees?

Co-ops in Manhattan generally have lower purchase prices per square foot than comparable condos. This price difference often reflects the restrictions that come with co-op ownership, including stricter board approval, subletting limits, and resale limitations.

However, monthly costs should be compared carefully. Co-op maintenance fees often appear higher than condo common charges because more expenses may be bundled into one payment.

What Are Common Charges vs. Maintenance Fees?

Condo owners pay “common charges” to the condominium association. These fees cover shared building expenses such as:

• Building staff salaries (doorman, superintendent, porters)
• Common area maintenance and cleaning
• Building insurance
• Elevator maintenance and repairs
• Reserve fund contributions

Condo common charges do not include property taxes. Condo owners pay their real estate taxes separately and directly to the city.

Co-op shareholders pay “maintenance fees” to the cooperative corporation. These fees generally cover shared building expenses and the shareholder’s proportional share of the building’s real estate taxes. If the co-op has an underlying mortgage, maintenance may also include debt-service costs. Because more costs may be bundled into maintenance, buyers should compare condo common charges plus property taxes against co-op maintenance rather than comparing the labeled fees alone.

Peter Zinkovetsky can help you analyze the financial statements of a condo or co-op building before you commit to a purchase.

How Are Real Estate Taxes Paid in Each?

Condo owners receive their own property tax bill from the New York City Department of Finance. Each condo unit has a separate tax lot, and the owner pays taxes directly to the city. Condo owners may be able to deduct qualifying property taxes on their federal income tax return if they itemize and meet current IRS rules and limits.

Co-op shareholders do not receive an individual tax bill. Instead, the cooperative corporation receives a single property tax bill for the entire building and pays it on behalf of all shareholders. Each shareholder’s proportional share of the building’s property taxes is generally included in their monthly maintenance fee. For federal income tax purposes, co-op shareholders may be able to deduct their allocated share of qualifying building property taxes if they itemize and meet current IRS rules and limits. The cooperative typically provides a statement each year showing the deductible portion of maintenance.

The practical difference is mostly administrative. Condo owners manage their tax payments directly, while co-op shareholders rely on the cooperative to handle the payment. However, if a co-op building falls behind on its property taxes, the issue can affect shareholders even if they individually paid their maintenance on time.

Can You Sublet or Rent Out Your Unit in New York?

Subletting rules differ sharply between condos and co-ops, and this distinction matters to buyers who may want to rent out their unit in the future.

Many Manhattan condos allow subletting, subject to the building’s declaration, bylaws, and rules. The board may require notice, tenant registration, or a minimum lease term, so buyers should review the building’s governing documents before relying on rental flexibility.

Many Manhattan co-ops either prohibit subletting entirely or impose strict limitations. Common restrictions include:

• A waiting period before subletting is allowed (often two to three years after purchase)
• A maximum subletting period (such as two years out of every five)
• Board approval of the subtenant
• A subletting fee or surcharge on the monthly maintenance
• A prohibition on subletting for profit

Before buying either type of property, review the building’s governing documents carefully to understand its specific subletting policies.

What Are the Rules for Selling a Condo vs. Co-op in New York?

Selling a condo is usually more straightforward than selling a co-op. The condominium’s governing documents may still require a right-of-first-refusal waiver or other transfer review, but condo sales generally involve fewer approval barriers than co-op sales.

Selling a co-op is more complicated. The seller must find a buyer who can pass the co-op board’s approval process, which includes the same application package and interview required for any new purchaser. If the board rejects the buyer, the sale may not proceed, which can add time and uncertainty.

Many co-ops also impose a “flip tax” on sales. A flip tax is a transfer fee paid to the cooperative when a unit changes hands. The amount varies by building. Common structures include:

• A percentage of the sale price
• A percentage of the seller’s profit
• A flat dollar amount per share

The proprietary lease, bylaws, or house rules will specify whether the seller or buyer pays the flip tax. These restrictions can affect resale planning and should be reviewed before a buyer commits to a co-op purchase.

Can You Renovate or Alter Your Unit?

Both condos and co-ops have rules governing renovations, but the level of oversight differs significantly.

Condo owners often have more flexibility to alter the interior of their unit, but the building’s bylaws, rules, and alteration agreement still control the process. The condo association may require advance notice, contractor insurance, board review, limits on construction hours, and protection of common areas during the work. New York law also restricts work that could jeopardize the safety or soundness of the property, reduce property value, impair easement rights, or affect other owners without required consent.

Co-op renovations require board approval. Most Manhattan co-op buildings require shareholders to submit an alteration agreement before beginning any work beyond minor cosmetic changes. The alteration agreement typically requires:

• Detailed plans prepared by a licensed architect or engineer
• Proof of contractor insurance
• A security deposit (refundable upon satisfactory completion)
• Compliance with building rules regarding construction hours and noise
• Board review and written approval before work begins

The board may deny a renovation request or require modifications to the plan. This process can add weeks or months to a renovation timeline. For significant projects, the co-op may also require approval from the New York City Department of Buildings.

Peter Zinkovetsky can review an alteration agreement and advise you on your rights before you begin any renovation project.

What Is an Offering Plan, and Why Does It Matter in New York?

Before a sponsor can make a public offering or sale of condominium units or cooperative shares in New York, an offering plan generally must be filed with the New York State Attorney General unless an exemption applies. This requirement comes from Article 23-A of the New York General Business Law, § 352-e, commonly known as the Martin Act. The Attorney General’s Real Estate Finance Bureau reviews offering plans for compliance with applicable state regulations.

The offering plan is a detailed legal document that describes the property, the terms of the sale, and the rights and obligations of buyers and the sponsor (the entity offering units for sale). Key contents of an offering plan include:

• A description of the property, including the building’s physical condition, construction details, and common areas
• The unit layouts, sizes, and allocated interests or share allocations
• The building’s projected budget, including anticipated common charges or maintenance fees
• The sponsor’s financial obligations and any reserved rights
• The terms of the proprietary lease (for co-ops) or the declaration and bylaws (for condos)
• Risk factors and special conditions

Prospective buyers should read the entire offering plan and have counsel review it before signing a purchase agreement. A cooperative or condominium purchase can create significant legal and financial obligations, and informal representations may not protect the buyer if they are not reflected in the offering plan, purchase agreement, or another binding written document.

For resale purchases, the offering plan and amendments remain important reference documents for understanding the building’s structure, rules, and risks. A buyer’s attorney should review the most current available building documents, including the offering plan, amendments, financial statements, and board minutes.

Which Is Better for You: a Condo or Co-op in New York?

The right choice depends on your financial situation, how long you plan to stay, and what kind of flexibility you need. Neither option is universally better. Each has trade-offs that affect different buyers in different ways.

A co-op may be a better fit if you:

• Plan to live in the unit long-term as your primary residence
• Can meet stricter down payment, liquidity, and post-closing reserve requirements
• Want a lower purchase price and are comfortable with higher monthly costs
• Value a stable, owner-occupied building environment
• Are prepared to go through the board approval process

A condo may be a better fit if you:

• Want full ownership of real property with a deed in your name
• Need financing flexibility with a lower down payment
• May want to sublet or rent out the unit in the future
• Prefer fewer restrictions on selling
• Are purchasing as an investment or pied-à-terre

The following table summarizes the key differences:

Feature	Condo	Co-op
What you own	The unit as real property, plus an interest in common elements	Shares in a corporation, plus a proprietary lease
Board approval	Usually no discretionary buyer approval; right-of-first-refusal review may apply	Usually required; detailed application
Down payment	Often more flexible	Often stricter
Financing	Traditional mortgage	Share loan
Monthly fees	Common charges; taxes separate	Maintenance; more costs may be bundled
Property taxes	Paid directly to the city	Generally paid through maintenance
Subletting	Usually permitted	Often restricted or prohibited
Selling	Usually fewer approval barriers	Usually requires board approval
Renovation	Often more flexible; rules still apply	Board approval usually required
Purchase price	Generally higher	Generally lower

Every building is different. The offering plan, proprietary lease, declaration, bylaws, and house rules will determine the buyer’s actual rights and obligations. Before making an offer on a Manhattan condo or co-op, buyers should have a real estate attorney review the building documents so they understand what they are agreeing to.

Key Takeaway: The better choice depends on the buyer’s finances, timeline, intended use, and tolerance for building restrictions, not just whether the property is labeled a condo or co-op.

Frequently Asked Questions: Condos vs. Co-ops in New York

Is a co-op cheaper to buy than a condo in Manhattan?

Co-ops in Manhattan often have lower purchase prices than comparable condos, but the lower price does not always mean lower total cost. Maintenance fees may include the shareholder’s share of building property taxes and may also reflect building debt if the co-op has an underlying mortgage. Buyers should compare purchase price, monthly payments, closing costs, and building financials before deciding which option is more affordable.

Can a co-op board reject my application without giving a reason?

In many New York co-op transactions, the board has broad discretion to approve or deny a purchaser and may not provide a reason for the decision. That authority still has limits. A co-op board may not reject a buyer for an unlawful discriminatory reason or act in bad faith, outside its authority, or in violation of applicable law.

Do I need a real estate attorney to buy a co-op in New York?

A co-op purchase in New York involves legal and financial documents that buyers should review carefully before closing. These may include the proprietary lease, offering plan, amendments, building financials, board application materials, loan documents, and closing paperwork. When you hire a real estate attorney, they can review those materials, negotiate contract terms, and help the buyer understand the obligations tied to the purchase.

What is a proprietary lease in a co-op?

A proprietary lease gives a co-op shareholder the right to occupy a specific apartment tied to their shares. It also sets out important obligations, including maintenance payments, alteration rules, subletting limits, default provisions, and other rights and restrictions that apply to the shareholder’s use of the unit.

Are co-op maintenance fees tax-deductible?

Part of a co-op maintenance payment may be deductible if it is allocated to qualifying real estate taxes or mortgage interest and the shareholder itemizes under current federal tax rules. Co-ops typically provide an annual statement identifying the deductible portion. Buyers should consult a tax professional about how the rules apply to their own return.

What is a flip tax in a co-op?

A flip tax is a building-imposed transfer fee that may be due when a co-op unit is sold. Despite the name, it is not a government tax. The governing documents control whether a flip tax applies, how it is calculated, and whether the seller, buyer, or both parties are responsible for payment.

Can I use a conventional mortgage to buy a co-op?

A co-op purchase is usually financed with a share loan rather than a conventional mortgage. The lender’s collateral is the buyer’s co-op shares and proprietary lease, not a deeded real property interest. Because not all lenders offer co-op share loans, buyers should confirm financing options early in the purchase process.

What is the difference between a condo association and a co-op board?

A condo association, often acting through a board of managers, oversees the condominium’s common areas, bylaws, rules, and shared expenses. A co-op board governs the corporation that owns the building. Because of that structure, co-op boards often have broader involvement in buyer approval, subletting, financial requirements, and shareholder obligations.
