Quick takeaways
- Single-family and townhome purchases generally include the land; condos generally don't — you own the interior space.
- A co-op is structurally different from the others: you're buying shares in a corporation, not real property directly.
- The more shared a property is, the more its HOA or board's health matters to your own experience as an owner.
Single-family home
This is the one most people picture: a standalone house, on its own lot, where you own both the structure and the land it sits on. There's usually no HOA involved (though some single-family neighborhoods do have one), which generally means fewer shared rules, but also full personal responsibility for everything — the roof, the yard, the driveway, all of it.
Townhome
A townhome is typically an attached home, sharing one or two walls with neighbors, where you usually own the structure and often a small footprint of land (sometimes a tiny yard). Townhomes are commonly part of an HOA, which typically maintains shared spaces (common areas, sometimes exteriors) in exchange for dues. What's shared vs. individually owned varies a lot by community, so it's worth checking specifically.
Condominium (condo)
Here's the part that surprises a lot of people coming from single-family homes: with a condo, you typically own your unit's interior space, and the building's structure, exterior, and shared amenities are commonly owned collectively, managed through an HOA. That HOA is usually responsible for things like the roof, exterior walls, and elevators — which is exactly why the HOA documents matter so much for a condo purchase specifically.
Co-op (housing cooperative)
This one is structurally different from the other three, and it catches a lot of first-time buyers off guard. In a co-op, you're not buying real property directly — you're buying shares in a corporation that owns the entire building, along with a proprietary lease giving you the right to occupy a specific unit. Co-op boards often have significant say over who can buy in, sometimes including a formal interview or approval process, which is uncommon with the other three types.
A side-by-side view
| Type | You typically own | Shared responsibilities |
|---|---|---|
| Single-family | Structure and land | Usually none, or minimal HOA involvement |
| Townhome | Structure, sometimes a small lot | Common areas, sometimes some exteriors |
| Condo | Interior unit space | Building structure, exterior, amenities (via HOA) |
| Co-op | Shares + a proprietary lease | Entire building (via the co-op corporation/board) |
What buyers usually review for each
- Single-family: general property condition, land boundaries/survey, local zoning
- Townhome: HOA rules and dues, what's shared vs. individually owned, reserve health
- Condo: HOA documents in depth (see the HOA guide), building-wide issues, insurance structure
- Co-op: board approval process, building financials, shareholder agreement terms, subletting rules
A helpful reframe
The more shared a property type is, the more your day-to-day experience as an owner depends on how well that shared entity (the HOA, the co-op board) is run. Reviewing those documents isn't extra homework — for a condo or co-op, it's arguably as important as the inspection.
What this guide is not
Ownership structures and their exact rules vary by state and even by individual building or community. This is a general, educational comparison, not a legal description of any specific property. A real estate attorney can explain the exact structure for a property you're considering.
