There is a large amount of scams posted as rentals. First thing if the price looks too good to be true, it probably is. Never rent homes sight unseen, never wire or mail money. 99.9% of real owners are not over seas and none will rent at a discount so you take better care of the home. You can easily see who the owner is by looking at the tax card at the assessors office. If someone is showing you the home, ask for an ID and make sure it is indeed the owner.
