Can the property management company increase the property management fee before the contract expires?

If the property management company raises the property management fee, it may require the property management company to produce relevant state documents. If you don't explain that the property is unilateral and has not been declared by the state, you can refuse to pay. However, if the property shows the national documents on the property management company's charging standard, then you must obey. Relevant property charging standards can be found on the national property management website. Property fees have little to do with the rise and fall of prices.
