If the developer has completed the property certificate of the house, and the property right and mortgage right have been registered for the record, then what should be done is done, and it is impossible for the buyer to change the house.

If the property right certificate of the house has not been processed, the buyer wants to change the house and negotiate with the developer, which is highly operable. Specifically, the developer and the buyer first cancel the original house sales contract, the developer pays off the bank loan in one lump sum, ends the loan contract between the buyer and the bank, and then signs a new house sales contract with the original buyer. If the new house still needs a loan, it needs to re-apply for a bank loan.

The key to this operation is whether the buyers can reach an agreement with the developers. If the developer does not agree to terminate the original contract, then the buyers can only look at the house and sigh; Even if an agreement is reached with the developer, the buyers will have some losses, including stamp duty, deed tax, some insurance fees, loan lawyer fees and so on.
