Under what section of Idaho law, can a lender not be entitled to collect a deficiency judgement for a purchase money loan? I bought a property in Idaho three years ago and they took it back, and now they want to sue me for the difference between appraised value and the loan amount. I have been told in CA law it is civil code 2924h but this appears incorrect.
