You don't have to reject any prospective tenants outright or cite reasons for doing so. Be careful if you choose to give reasons for denying tenant applications (we don't recommend doing it at all) - Never quote illegal reasons such as race, color, religion, sex and nationality.
First, make sure you have cause to terminate the tenant's lease. Renting your property may be business to you, but it's your tenant's home, and you can't evict for just any reason. The tenant does not pay rent, and does not have any good reason for withholding rent such as a warranty of habitability claim. The tenant violates a provision in the lease, such as smoking in a non-smoking apartment. The tenant violates some duty imposed by law.
