Step 1. Order a screen of your prospective tenant at E-renter.com. For a fee of $30 you'll get a credit check, eviction report, and criminal-record check. You want to see no past evictions or crimes and a history of paying bills on time, says Allison Atsiknoudas of Rentometer.com.
Step 2. Ask where he works and how much money he makes. Look for the applicant's pretax income to equal at least three times the rent you're charging or he may have trouble covering it. Call his employer to verify that he works there and that his pay is what he says it is.
Step 3. Call his current landlord -- and his previous one -- to verify his tenancy. A key question to ask: "Would you rent to this person again?"
Step 4. Assuming he passes the screens in steps 1 through 3: Say hello to your new tenant!
