Rental income fluctuations

[Aaron Thompson]

Hello BP family. How does one estimate the fluctuation of rental income on a cash flowing properly accurately. I know of a website called rentometer.com. I am looking to buy a rental property in the near future and I wanted to know how do I know when to increase the rates and at what time. Are there any books that you can refer me to that could help me in this process. I have read the BRRRR book And I had spoken of a website that I can use but I want to get more in depth so that I make the right decisions about the prices. I know that I can also use the comparable rents in the area. Are there any other methods of figuring out the rental prices that I should charge my tenants?
