I think it’s because they are intoxicated by the high that spending brings, and they are also trying to keep up appearances like everyone else in the neighborhoods. And let’s not forget, the mortgage folks tell you not to dork with anything that will affect credit ratios until after closing. When you think about the expenses associated with buying a new home, the last thing I’d want to spend money on is a car! Window treatments, landscaping, furniture, etc…it’s a fortune!
