When buying a second-hand house, if you look at the following parts clearly, it is unlikely that there will be a big problem.

1. Verify whether the property right is clear: the seller must be the owner of the house, which can be verified by checking the property right certificate and the ID card of the property owner.

2. Verify the housing situation: When looking at the house, we should start from the following aspects: housing construction, housing community and housing rights. The verification of these situations will help you control the actual cost and risk of the transaction.

3. Clear transaction procedures: Second-hand housing transactions can be divided into several steps: house inspection, contract signing, down payment according to the contract, transfer, delivery and balance payment. Attention should be paid to these steps: keep the transaction evidence, transfer the ownership only when everyone on the property certificate is present, and check whether the other party has paid the property fee, water, electricity and gas fee when handing over the house.

4. Clarify the liability for breach of contract: Clarify the strict liability for breach of contract with the seller, which is the guarantee for both parties to perform the second-hand housing sales contract in good faith. In practice, small down payment punishment or simple "the breaching party should bear the losses of the observant party" lacks practical effect. When house prices fluctuate, funds are insufficient, and taxes and fees are reformed, one party delays or refuses to perform the contract from time to time. If some buyers think that the house price is too high or do not want to pay the transfer tax after signing the contract, they will delay the transfer formalities, resulting in the seller not receiving the balance in time after handing over the house; Some sellers found that house prices soared, saying that the sales contract without the consent of other co-owners was invalid and asked the buyer to return the house.
