the invoice for the maintenance fund should be reissued. According to the relevant public information, the purchase of second-hand houses requires the original owner to issue a overhaul fund invoice, which needs to be handed over to the new owner after the formalities are completed. If the bill is lost, it can be printed at the Housing Authority. The housing maintenance fund is managed by the housing construction department. Please consult the housing construction department for real estate transfer registration when the invoice is reissued. No materials related to the housing maintenance fund will be collected, which will not affect the transfer registration.
