You probably can get a tenant's application form at a stationary store. Some software programs like Family Lawyer also have apps in them. The app usually has a space that tells the prospective tenant you will run a credit check and they have to sign to allow you to do so. Being a slum landlord for many years, I would run the credit checks, reference checks, former landlord checks, and everything I could think of to find out if the person would be good to my investment. You have to protect it.
