I have a quick question about back rent. How long do you have to wait before you can evict a tenant for not paying rent? You know like one month, two months, what? I'm in Illinois so if anyone knows Illinois law?
You have to issue them a pay or quit letter, generally. If you are a landlord, you really should research your landlord and tenant laws. This is basic info you need to know. You then need to properly serve them with an eviction notice.
