YOu can run credit checks yoursel, if you have the tenants signed consent. If you are not a seasoned landlord you may find it wise to use a local Realtor or rental agent to find a tenant. They will not only run the credit check and read it for you, they will advertise the property for rent, interview potential tenants, take applications, show the property for you and check out rental history references of those who show promise. Once a likely tenant is identified, many agents will consult you for a final decision before preparing a lease for the parties to sign, collecting 1st (or 1st and last) month's rent and security deposit, and see the tenant into the property. In exchange for these services, the real estate rental agent typically is paid 1st month's rent. Ask if they will manage the property on an ongoing basis and what that fee will be. In our area 8 -10% is typical. Someone needs to be available to collect the rents (and follow up if the tenant has not paid when expected), answer the tenants' calls that inevitably come in at odd hours. It may be leaky pipes or a broken window, lack of heat or a noisy neighbor. You want someone who can deal with tenants in a firm but caring manner.
Ask around! Who has a good reputation in the area for handling rentals. Ask for references from the agent and interview them to know if you are comfortable with them and the way they work.
Learn all you can so that you are an informed consumer.
Hope that helps.
