Idaho Code § 45-1512
At any time within 3 months after any sale under a deed of trust, as hereinbefore provided, a money judgment may be sought for the balance due upon the obligation for which such deed of trust was given as security, and in such action the plaintiff shall set forth in his complaint the entire amount of indebtedness which was secured by such deed of trust and the amount for which the same was sold and the fair market value at the date of sale, together with interest from such date of sale, costs of sale and attorney's fees. Before rendering judgment the court shall find the fair market value of the real property sold at the time of sale. The court may not render judgment for more than the amount by which the entire amount of indebtedness due at the time of sale exceeds the fair market value at that time, with interest from date of sale, but in no event may the judgment exceed the difference between the amount for which such property was sold and the entire amount of the indebtedness secured by the deed of trust.
