First of all, you must keep the bank receipt when you transfer money to him.
Second, increase the deposit, because to be honest, even if the owner breaches the contract 10000 yuan, he will compensate you 10000 yuan, and the owner will not lose money if he sells it to others at a higher price, so if you have this concern, you must increase the deposit. If it is increased to 65,438+1.2 million, the owner will not dare to breach the contract because he can't afford to lose.
Third, the intermediary will issue a down payment receipt certificate and a down payment receipt certificate. It is best to print all the above contents, because it is easy to be modified by handwriting. After filling it out, sign it with your handprint.
Fourth, there should be a supplementary agreement when signing the contract. The supplementary agreement should fully reflect these contents, which is to prove how much money you have paid to the owner. The supplementary agreement should have the seal of the intermediary company, which is more secure.
In this case, it is generally no problem.
