After reading your situation, I would like to ask, does your house lease contract indicate the value of that set of things in the rented house? If not, you can directly recover the deposit of 7000 yuan from him. According to the burden of proof, the landlord needs to prove the loss himself. If he can't prove it, it's not up to him, so don't be afraid of him. Let him take out the certificate, and the judge will take it when he goes to court. If he doesn't, he will accept it.
