Many smart PC'ers will say that "buy below market value". While market value is debatable because no two houses sitting next to each other with same features like 3/1/2 don't sell for the same price. So all the bank estimation tools, price finder, Onthehouse everyone of them have differing estimates (some are broad ranges of about 75k!) So when you do decide to buy a property: 1. How do you determine market value? 2. How do you know what amount equity you will get after the purchase? 3. How soon after the purchase do you pull out the equity?
