Guidance for Multifamily in Stillwell Kansas

I am currently looking into buying a 9 unit building in Stillwell Kansas. Just south of Overland park. I am not very familiar with the area so I am looking for some guidance. They are all mostly renting for about 400-500 a unit, when I run a rentometer report it says the median close to that area is around 800-900. Would this area rent as well as that report is saying? Trying to get current leases from owner to find out how long I am stuck into these rents. My question, is this area worth investing in? Can I bank on getting those rent rates as reported by rentometer?
