Condominiums and Townhomes are different.  A Condominium is a type of ownership, and a Townhome is a building style.  The confusion comes from Condos listed as "Townhome" or "Townhouse Style." Still, it all comes down to the legal description of the property.  In a condominium, the unit owner has a right to occupy their unit and fractional ownership in the whole complex.  A Single-Family Residence is where the homeowner owns the home and the land that it sits on.  A "Townhouse" can be a Condominium or a Single-Family Residence, depending on the legal description of the property.
