I have owned rental properties in the past. I don't right now but I may do so again. First, NEVER under any circumstances rent to section 8 type of renters. That right there will cure about 50% of issues before they even start. Second, always take a deposit for each animal, as well as a deposit on the rent itself. I did first and last times two for the deposit on the rent. Third, if they have dogs specify what breeds you will not allow. As bad as it sounds people who have PWT dog breeds trashed my rentals every single time so I stopped allowing people with that type of dog to rent. Plus your insurance on the place goes sky high when your renters have any of the PWT dog breeds, pitbulls, rottweilers etc. Always set the max number of any type of animal you allow unless it is a farm property with appropriate facilities. Almost no renter will ever take as good care of your place as you would so you have to be prepared to do corrective work between each renter. I have had to do thousands of dollars in repair work between renters so make sure the deposits will cover that. Also don't rent to people with poor credit and always run a criminal background check and a credit check. Also make sure your contract specifies what kind of home businesses they can and can't run or you end up with renters running grow ops indoors and the house fills up with mold and other even nastier things.
