Revisions log for Answer #644

The answer is as simple as it is complicated. The basement, of course, is much more expensive than the garage. A basement has functionality and, above all, a direct connection to the house. The garage, on the other hand, can serve many functions, including a workshop and party space; perhaps it is also connected to the house, but is more of an outside area. As with many real families, the price will be determined by the frequency of use.
