Legal analysis: 1. The collection time of maintenance fund is when the house is delivered for use. When the purchaser purchases the house from the developer and handles the transfer of property rights, the payment ratio is 2% to 3% of the total house price, and it is paid to the commercial bank designated by the real estate department in the district where the house is located. The specific collection standard of maintenance funds is determined by the local real estate administrative departments according to local conditions. 2. Maintenance fund, also known as "public maintenance fund" and "special maintenance fund", refers to the fund that the owners of residential properties pay a certain amount to a special account for the maintenance of public parts and facilities and equipment in their property area, and authorize the owners' committee to manage and use it in a unified way. 3. The maintenance fund is jointly raised by the property owners, who enjoy the ownership of the maintenance fund according to the proportion of payment, but the right to use it belongs to all owners, and a single owner may not withdraw all the maintenance funds from the bank. The maintenance fund is combined with a specific house, exists with the existence of the house, and is also lost with the existence of the house, and does not change because of the change of the specific owner. When the house property right is changed to a new owner, the maintenance fund should also be renamed from the old owner to the new owner.
