Start by figuring out is the tenant on a month to month or in the middle of a lease, next is the tenant violating any rules or failing to follow any guidelines? What about behaviour? Is the state lease abiding the state laws? Is the tenant violating laws and or not paying rent on time or just not at all? This is just a few things but if any are met than send out an eviction notice and think about getting an attorney. You will then go to court and you will need witnesses. Then the conviton will be made. Win or lose depending on information. <span />
