Tenant just messaged me they are braking the lease in one month.

[Salomon W.]

It's a single family house for rent here in NY state. Tenant just let me know they're braking their lease and are leaving in 30 days from now. In addition they don't want to pay for the last month rent and are forcing me to use their full security deposit to fund the last month,

Even worse, they don't want to allow potential tenants to look at the house before they leave. It's an expensive house and I want them to leave the property not being upset on me so they don't damage the house intentionally.

What do I do? Any advise?
