Those tours are for the vulture investors who buy homes cheap, fix them up, and then rent them out. Try buying a home to actually LIVE IN and you have to compete with those people. Thankfully, if your real estate person is good they'll let whoever is selling the house know that you plan to live in it and they'll look at your offer more seriously. The house I'm in right now had about five other offers on it, and no one was actually going to live in it. They just wanted another rental.
