First: if the new house handles the triple order normally, it does not need to be re-evaluated. The price on the invoice should be a price certificate, but this is the house price of the year.
Second: you entered the household in 2007, but the developer didn't have all five certificates in that year, or the community was not fully developed, so you didn't apply for the real estate license normally in that year. The reason is not you, but the developer. If you follow this law, the developer should pay the extra tax you get.
Third: Therefore, it is necessary to unite community owners, set up owners' committees, safeguard rights and take up legal weapons.
Fourth: whether it is necessary to re-evaluate, this real estate department is also illegal (because according to the law, housing registration is not based on price, but on cases; Taxes and fees shall be subject to the transaction price. The administrative organ arbitrarily increases the pre-procedure), but this is sometimes force majeure. Good luck to the landlord.
