A tri-merged credit report is required with a middle credit score of at least 620. Depending on overall credit, sometimes borrowers may qualify with middle scores as low as 580. In some instances, where a co-borrower does not have any credit scores, FHA will consider approval so long as the primary borrower meets the minimum credit score requirements and has more than 50% of the qualifying income with a minimum of 3 tradelines active for last 24 months. Regardless of credit scores, FHA still evaluates overall credit history to determine if borrower gets approved eligible findings that meet FHA approval guidelines.
