Misrepresented the fact that I was approved for my loan, and I dropped my loan contingency on reliance of that misrepresentation. Two weeks before closing, I was notified that my rate was going to be 0.25% higher. Her explanation was that she wasn't aware of new lending requirements that had been in effect for over 7 months and that I didn't qualify for that loan anymore.
Also, she miscalculated my new monthly payments, so I decided to move forward with the higher rate based on the fact that the payments would not be that much higher (and the fact that I was notified two weeks before closing and after removing loan contingencies). Then, when I looked over the loan documents (a week before closing), I realized that the difference in monthly payments was going to be twice what she originally told me. Her explanation was that she miscalculated.
