Doesn't section 8 require a property to pass some kind of inspection to qualify? What if something happened to the property so it didn't pass any more? Problem solved.
Inspections tend to be annual. That might be a long time to wait.
And purposefully damaging your own property sounds like a bad idea.
And if your property fails the inspection, they stop paying you until you fix it.
That doesn't magically remove the tenant.
So now you have the tenant, no payment from section 8, and still have to evict.
And if you do something to make it uninhabitable (like shutting off utilities), look for a giant lawsuit with large damages.
All in all, please ignore the quoted post. :) I know it was hypothetical, but the answer is a clear: no. Stay far, far away from this.
Heck, the great thing about the current situation is the OP is still getting MOST of the rent while trying to evict, that's rare. Shutting that off seems quite silly to me, all of the above legal issues aside.
