Section 8 tenants & evictions

[Mike Abramowitz]

So I purchased a few units back in Portland, CT in January and currently in the process stabilizing the property. It has come to the point where all the tenants are on month to month leases, in the beginning of March we notified a tenant who is section 8 that we are not planning on renewing her lease. (Which ended 5/1) We've received many complaints from other tenants in the property, the police have shown up in relation to this tenant and its not the positive living environment which we strive for in our properties. However, when we told the tenant and the housing authority we were not renewing her lease we did not give a reason (as that was the advice give to us by a few landlords in the area who deal with similar tenant situations) 

Well the first of the month came around and the tenant refuses to move out. The housing authority has let us know that as long as the tenant is still there they will continue to pay rent.

What advice does anyone who's gone through this process before have?
