Large yard property just buy it and close the escrow.
However, if you don't like the house, and want to cancel the deal, you should do nothing and let the time pass. 最壞的情況是你損失你的deposit. You and the seller are still under contract, without your signature to cancel the contract, the escrow will not release your deposit to seller, and also the seller can't sell to others, (maybe foerever if you are not cancel). 一般這種情況下，賣方比買方更著急，都會退還定金。
更壞的情況，上了法庭，如果判你必須買這房子，also just let the time pass, you still under contract. 二十年後，房子大大增值，你你的合同價still the same. You even can also put a lien on the house to give the seller more pressure.
作為賣家，我遇到過幾次買家反悔，我都是簽字退錢，move on. 不確定性是投資者的大忌。
If you just like to ask 幾千元的補償或降價，我覺得你還是應該close the deal. 貪圖小錢也是投資者的大忌。Thinking carefully before you sign the contract, but following the contract after you sign.
