So when you get to inspections (or your realtor whom doesn't know much about investments, or your inspector who is filling your report with things that are irrelevant to you making money and being able to keep a happy tenant) often much more needs to be done than was disclosed and often these "deals" are being sold as is. 5) you realize that you can make the numbers work, but it's not a great deal.. and this is when so many investors will swoop in and say "it's fine, you don't need a home run!"
