Is it permissible to work as a financial manager in a real estate appraisal company that deals mainly with banks to appraise properties for loan and financing applicants, knowing that the company charges a fee for each appraisal?

Working in real estate appraisal for banks is permissible if the banking transactions are Sharia-compliant, such as Murabaha for a purchaser, which means the bank buys the property for itself and then sells it to the client. However, if the banks' transactions are based on usury, such as the bank lending money to the client or paying the price of the property on their behalf to be repaid with an increase, then this is prohibited usury. It is not permissible to assist in it in any way, including appraising the property, based on the Almighty's saying: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression), and the Prophet's saying (peace be upon him): "The Messenger of Allah (peace and blessings of Allah be upon him) cursed the one who consumes Riba (usury), the one who gives it, the one who writes it down, and the two witnesses to it," and he said: "They are all equal (in sin)." So, if the job requires dealing with usurious banks, it is not permissible to engage in it.
