query: RESPA 2010 can you stop a closing due to a 10% tolerance issue

I'd sure be surprised if a lender permitted a HUD to go to closing without a cure, however they do have the option of closing and curing the tolerance violation within 30 days after closing.  In my non-attorney opinion a consumer must make a decision to close or not.  If it were me and I felt strongly that there was a tolerance violation, I would not close unless I had in hand a signed letter
