Maybe real estate works different in Buffalo, but everything I'm saying works fine in San Diego. The cheapest crap house fixer upper in San Diego starts at 500,000. So buying a house in San Diego at 720K can use a lot of work.
Are you saying that no one adds square footage to a house in Buffalo after the fact ? Or are you just being silly ? Besides, no one has said that the house Willis bought is new or 30 years old ? I'm assuming it's older since it's been speculated that it is the cheapest house on the street and I'm assuming others have been bought and improved upon making them more valuable over time.
Also I'm tired off being insulted for making a few assumptions about this house and my professionalism just you because you knuckle draggers don't fully understand how real estate really works. Believe it or not, people buy houses, fix them up by improving them and sell them for a profit. I do it all the time. It's one of the ways I make a living.
