tenant's right in hardship
I am a landlord, and my tenant's lease is up next month. Since they did not want to renew the lease, I started to show the unit to prospective tenants. But one day my tenant refused to let us into the unit, even though I gave them more than 24 hours notice by talking to him in person and also handed him a letter with the appointment date and time on it. His wife recently was diagnosed of brain tumor, they have a little baby. I want to know what my rights are and their rights are if they refuse to leave at the end of the lease. Is the law on their side if they have some hardship?
