. . . If I agreed on a price, then that is the price. Is the sale price not legally binding after the contract is signed? Barring any contingencies of course...
1) Yes, the signed contract is the sales price.
2) However, the Buyer or Seller can back out anytime prior to paying money at Closing.
. . . either can try to sue
. . . but, legal cost usually outweigh the gain
. . . plus, it could take years to go to court
3) You may or may not lose the Earnest Money.
4) But, most of the time, the Buyer HAS TO CLOSE.
. . . they have already bought another house
. . . they are in the process of moving to another city or state
. . . they haven't had many bites and are afraid of not selling again for a while
6) I have also seen the Seller come to Closing and ask for more money.
7) The Closing Company FREQUENTLY comes to the table and wants more money.
5) Let's face it, like ALL selling situations
. . . the Seller wants as much money as possible
. . . the Buyer wants as little money as possible
. . . the Closing Company wants as much fees as possible
6) It is still, THE ART OF THE DEAL.
