<prompt> Human: I am wondering what my options are, and mostly, do I have to pay this? Is he accountable for any of the error?Edit: In escrow to buy my first house in California with an FHA loan.Update: The lender has agreed to pay for his miscalculation himself after a little pushback from me. I never had to threaten to walk, but simply told him that I didnt think I should be responsible for his mistake. Thanks to everyone who posted...your input let me know I wasnt crazy for thinking I was being mistreated here!  <response>: Essentially closing costs much of it paid at the end of the deal before closing are estimated but your agent should have estimated high. At this point, if heshe isnt willing to issue closing credits to cover the 1800 them you can walk away from the deal. You would lose the house but youll be able to find a new agent. Use it as a scare tactic for your agent. Tell himher youre going to walk out on the deal if they dont figure out how that 1800 will be covered and not by you.
