If the seller just wants to sell the house price higher and consider selling it to a new buyer, it is necessary to find out for himself whether the extra price of the new buyer can offset the liquidated damages that need to be paid to the original buyer.
If the seller wants to sell the house to the new buyer because the original buyer fails to pay the house price on time, it is suggested that the seller cancel the contract with the original buyer before signing the contract with the new buyer to avoid becoming a defaulting party.
