Use the tenant`s social security number and other information provided to perform a credit check at the agency of your choice. Some agencies also want you to fax or email the form signed by the tenant who accepts the credit check. As a landlord, your primary responsibility is to find excellent tenants who occupy the property – tenants who pay the rent and take care of their rented home as if it were their own. The difference between looking for a large tenant and a tenant who turns out to be deadbeat can be determined in the information you discover during a credit check of a potential tenant. The cheapest way to conduct a credit check is to do it yourself. .
