Tenants with month-to-month leases can be terminated with the proper amount of notice, as long as your reasons are not illegal -- that is, as long as your reasons for booting out the tenant are not discriminatory or retaliatory. Tenants in only a couple of states -- New Jersey and New Hampshire -- and in some rent control cities enjoy "just cause" eviction protection. This rarity means that the landlord must have a legally recognized reason for terminating the tenancy. But even in these states or cities, your reasons would probably suffice.

So you may legally be entitled to evict. But as with most things in life, it's better to work out what you need without engaging in a messy legal battle. Continue to work with Eldercare to find suitable replacement digs for the tenant.

If all else fails, consider seeing an attorney, who might be able to impress upon your tenant that while you are not personally mean, you do mean business.
