@NedCarey Yea that's the idea. If you buy right it seems like you should be in the black after six months or so.
@Eddie P. I believe that used to be the case but from my understanding of the Protecting Tenants at Foreclosure Act of 2009 that is no longer the case. Also I am not certain but I believe leases of more than two years for residential properties are not enforceable. As far as being served what you said makes sense. As long as they understand the situation I don't see that as a problem.
"Before President Obama signed the "Protecting Tenants at Foreclosure Act of 2009," most renters lost their leases upon foreclosure. But this legislation provided that leases would survive a foreclosure. The tenant could stay at least until the end of the lease, and month-to-month tenants would be entitled to 90 days' notice before having to move out (this notice period is longer than any state's non-foreclosure notice period, a real boon to tenants)."
