Human: What are some of the main differences between a condo and a townhouse? Assistant: 
Some of the main differences between a condominium and a townhouse include: 
1. The type of ownership; with a condominium, you own your unit outright, while with a townhouse, you usually own a share in the property with other owners.
2. The number of units per building; typically, condos have more than one unit per floor, while townhouses will only have one or two units per building.
3. The amount of common space; condos often come with larger shared areas such as hallways, lounges, and outdoor spaces, while townhouses may have smaller shared areas like a patio or balcony.
4. The size of each unit; condos tend to be larger than townhouses due to their extra living space.
