When you have a property in need of a tenant, you cannot simply place an advertisement online, accept their money, and hope for the best. As the owner of the property, you are liable for what happens there. If unsavory folks end up living in your home, you could end up paying the price. While the temptation in a volatile housing market such as Arizona’s might be to just accept a tenant on the basis of his or her financial ability to pay you, keep in mind that your property is an investment deserving of the kind of care you might give to your own house.
