I am carrying a note... best way to check borrower's credit?

[George P.]

Good afternoon

I am going to carry a note on an investment property.

Its short term (3 or 5 yrs), high % (10-12), but rather small amount (9-10k).

The guy puts down about 40 % of the selling price.

Now to the question - whats the best way to check his credit? Not so much to see what's on it, but to have it on record in case I ever need to go after him in case of non-payment.

Thank you in advance!!!
