It will depend on your rental agreement. If you have a lease, then, no, you cannot evict them. If you have a month to month agreement, then you can give them appropriate notice to vacate. If you have a lease, and due to unfortunate circumstances, you may just approach the tenant and talk to them. Sometimes, they may agree to vacate earlier for certain concessions (I month free rent, some may ask for some money). Tenant has to agree to early termination of their own free will. But at the end of day, you have a legal contract with them (lease) and you cannot evict them/force them out of house because your personal circumstances have changed. Worse case, you will need to rent elsewhere and move in to your property when lease is up (In this case, make sure you give them appropriate notice that you are not renewing the lease and that they need to move out).
