made the function payable to accept ether.
transferred the funds to contract instead of seller.

There is still error in your code
Please re-check it

The require tag is used so as to check whether the transfer to seller is successful or not.
The transfer of the NFT is done and finally the property token is removed from the property sale list.

@Ansh-Agrawal1817
But the code doesnt correct the logic , To be precise the seller is not payable

@TechWizard9999
Kindly review it now.

@Ansh-Agrawal1817
