Which of the following is a residential dwelling with shared walls?

A townhome, or townhouse, is defined as a residential dwelling that shares walls with one or more neighboring units. This architectural style typically involves a series of homes that are attached in a row, where each homeowner owns their individual unit while sharing common walls. The design allows for denser housing, which can make townhomes a popular choice in urban or suburban settings where space is limited.

In contrast, an apartment refers to a rented residential unit within a larger building. While apartments may also involve shared walls, the emphasis is more on the rental aspect and the overall structure than on the ownership that characterizes townhomes.

A condominium (condo) is a similar concept in that it can involve shared walls; however, it is primarily defined by the ownership structure where units are individually owned but common areas are shared.

A single-family detached home stands out as a standalone structure that does not share walls with any adjacent dwelling, which distinguishes it significantly from townhomes.

Understanding these distinctions is crucial for real estate professionals, as they impact the types of listings and marketing strategies used for different property types.
