When verifying rent from previous or current landlords, I suggest you try this: ask the landlord to verify a rent that is significantly higher or lower than what your tenant applicant says they paid. Chances are very good that the true landlord knows what the rent is and will be able to correct your mistake. If the landlord agrees with whatever dollar amount you said, they could be an imposter covering for the tenant. This is not a guaranteed way to find out if you’re speaking to the true landlord, but it can give you some clues on how to proceed. Be careful out there!
