I use a company called Accurate Credit (www.accuratecredit.com) but there are lots more out there. Starting at $19.95 you can get credit and background information on your candidate; this is a good investment. You’ll be required to have a signed lease application from the candidate, along with their consent to run the check. This is useful for higher-end properties, but is significantly less useful for lower-end properties, where the tenants often have poor or no credit. In these situations you’ll need to use other methods of verifying the candidate’s reliability, primarily contacting their employer and previous landlord. But the bottom line is, if something smells fishy, don’t ignore your instincts.
