回复：紧急求助

how long have you owned your house, You can sue your buy agent and sell agent because of this false disclosure and agency duty if not very long(not sure which state you are, normally 2-4 years). However, your loan company should not ignore this mistake. Did you check the survey from your previous contract. This is area normally from the builder, and it is used for tax purpose as well. So I think you should double check your appraiser first.
