Condo vs Townhouse vs Co-op vs Apartment: The 4-Way Comparison

Updated 20 May 2026

Most online comparisons cover two at a time (condo vs apartment, condo vs townhouse). The honest decision often requires looking at all four together, especially in metros where all four exist (NYC, Boston, Chicago, DC). Here is the comprehensive side-by-side, including the legal structure, financing realities, monthly costs, and which buyer profile each fits.

Factor	Condo	Townhouse	Co-op	Apartment
Legal structure	Deeded ownership of unit + share of common areas	Fee-simple ownership of unit + land + sometimes shared common areas	Shares in a corporation that owns the building; proprietary lease for occupancy	Lease agreement; no ownership interest
What you own	Interior walls in; building is shared	Whole structure top to bottom + land underneath	Shares + lease, not real property	Nothing; right to occupy for lease term
Monthly cost structure	Mortgage + HOA + tax + HO-6	Mortgage + HOA (if any) + tax + HO-3	Mortgage (rare) or share loan + monthly maintenance + tax (in maintenance)	Rent + renter's insurance
Financing	Conventional, FHA, VA on approved buildings	Standard conventional, FHA, VA (most flexible)	Share loan from limited lenders; banks restrict; lower LTV	N/A
Approval barriers	Lender approval only	Lender approval only	Lender + co-op board (interview, financial review, sometimes rejection)	Landlord approval (credit, income, sometimes interview)
Customisation	Interior renovations per HOA rules	Maximum freedom (you own the structure)	Most restrictive; board approval for most changes	Minimal; landlord approval required
Monthly fees	HOA $200 to $2,500/mo typical	HOA often $0 to $400/mo if PUD	Maintenance $500 to $5,000/mo (includes building taxes)	Bundled into rent
Resale speed	30 to 90 days typical	30 to 60 days typical (broader buyer pool)	60 to 180 days (board approval required)	Sublet rules vary by lease and city
Appreciation potential	3 to 4% national average	4 to 5% national average (land component)	Slower than condo due to financing and resale friction	Zero (you have no equity)
Best fit	Urban, low-maintenance, lock-and-leave	Suburban, family-friendly, light-touch HOA	NYC, NJ pre-war buildings, long-term stable owner-occupants	Flexibility, short-term, mobility

The co-op nuance most blogs gloss over

Co-ops are concentrated in NYC (where they account for roughly 70% of Manhattan owner-occupied apartments), parts of NJ, Boston, and DC. The defining feature: you do not own real property. You own shares in a corporation that owns the building, and a proprietary lease that grants you the right to occupy a specific apartment. This has three large consequences:

The board can reject buyers without explanation (within fair-housing limits). Some prestige co-ops reject 30%-plus of applicants.
Financing is harder. Many banks will not lend on co-ops; those that do offer 'share loans' with lower LTV (often 70% to 75%) and limited rate competition.
Selling takes longer. Board approval requires a financial package and interview, adding 30 to 90 days to a sale beyond contract.

The upside: co-ops often trade at a 20% to 30% discount to condos in the same building or block. For owners with strong financials and long horizons, that discount can be excellent value.
