If the buyer of your real estate property is refusing to follow through with the purchase, there are a few steps you can take:

1. Review the purchase agreement: First, review the purchase agreement to determine what the buyer’s obligations are and whether they are in breach of the contract.
2. Communicate with the buyer: Try to understand the buyer’s reasons for not wanting to complete the purchase. Is there a specific issue that is causing them to back out? If so, see if there is a way to address their concerns and find a solution.
3. Consider your options: If the buyer is in breach of the contract, you may have legal remedies available to you, such as the right to sue for breach of contract or to seek damages. Alternatively, you may be able to negotiate a mutually acceptable resolution, such as allowing the buyer to terminate the contract in exchange for the return of any earnest money deposits.
4. Consult with an attorney: If you are unable to resolve the situation on your own, it may be necessary to consult with an attorney to protect your interests.

It is important to approach this situation in a calm and rational manner, even if you are feeling frustrated or upset. If you can work together with the buyer to find a solution, it may be possible to avoid legal action and move forward.
