Always ask for a copy of the renter's Drivers License. This verifies the renter's name and their home address. Google their names for additional information... Amazing what comes up with a bit of research.
Also, when a prospective renter is speaking with you, ask lots of questions. Smokers? Pets? People to visit them? (If they plan on having visitors, there should be additional charges for each night a guest is there. Or you can restrict the rental to one couple - the people named on the rental contract). Visiting children or grandchildren? (Is the home that you are going to rent child friendly?) Ask the potential renters where they have previously rented and why they are not renting that home, again. With a lengthy conversation, you can get a good indication if they are the right renters for your home. Be picky! Remember, you are handing over the key to an expensive home.
