Why is there a charge for changing rooms?

Property rights exchanges are generally divided into general fees and policy fees. General expenses refer to personal taxes and fees charged by the financial department, the Housing Authority and the Evaluation Bureau. For example, if the house is transferred from 1 to 5 years, the buyer needs to pay personal income tax; What the property department wants to collect is the tax paid for the first transfer; The Housing Authority will charge fees according to the size of each square meter of housing area; Of course, the housing appraisal fee charged by the appraisal bureau depends on the relevant regulations of each bureau. Finally, there is a fair fee. 2. Policy fees generally refer to deed tax, business tax, real estate transaction fees and stamp duty. If there is an intermediary in the middle, then add the fees charged by the intermediary. What's more, our country's laws stipulate that the exchange and transfer of house ownership should be registered by the parties concerned. Moreover, the registration procedures for housing transactions should be paid, and fees should be paid to the registration department, such as registration fees and housing transfer fees (calculated by the square of the real estate area).
