Intrust Funding only uses a soft credit pull and this does not affect your credit score.
Hard money lenders do run credit checks. Intrust Funding, however, requires no minimum FICO score, and the loan approval itself is not contingent on any credit score minimums.
Hard money lenders typically do not take a borrower's credit history into consideration during the underwriting process. What is most important is the after repair value (ARV) of the investment property itself.
