What should I pay attention to when buying a second-hand house?

1. Pay attention to whether the property fee and heating fee of the owner have been settled. 2. Pay water, electricity and gas (if there is a card, the owner must give it to you). 3. gehuayouxian (handover in gehuayouxian requires the set-top box left by the owner and the card in the set-top box). 4. Check whether there is a fixed telephone, network cable or something, and some try to get the owner to move away, or report for downtime. I suggest you change the lock cylinder after you take the key.
