Credit history: If locally allowed, landlords can request a credit check that will need to be authorized to complete. A landlord credit check helps determine if you're likely to pay rent. Credit Report: Credit report is required for all applicants with a preference for applicants who have a credit score of 650 or higher. In Massachusetts, you're allowed to request a credit report as part of the application process. Just got a rental property (duplex based in MA). How do you all run background and credit checks for your tenants? Tenant applications remain valid for 30 days from the original date of submission.
