Tenant wants out of 1 year lease after 6 months due to health

[Marcia Johnson]

What to do with a good tenant that wants out of their 1 year lease after 6 months.  It is a senior that can no longer care for themselves and the family is wanting out of the 1 year lease after 6 months.  The tenant has been there for a year and a half with no issues.  The lease states the tenant is responsible for future rents and costs if they breach the lease.  There is a security deposit. What have others done?
