When a realtor quotes the square footage of a townhome keep in mind that the actual liveable square footage is less than quoted by 200 square feet for a one-car attached garage and 400 square feet for a two-car attached garage townhome. In Chicago, square footage on a listing sheet includes the garage space for the home.
It is also important to know the wider a townhome is the better the resale. Typically in Chicago, the most horizontal townhome you can purchase is 24ft wide. That is wider than a typical single family home that in on a 25ft x 125ft lot. Townhomes that are this wide typically are in the $800,000 range and above. Note, there are also homes that are 16, 18 and 20 ft wide.
