In Rhode Island, if you rent a house or an apartment in a house that has been foreclosed there are absolutely no laws in place to protect the tenant. Therefore they have no rights at all. I've made a few calls and spoke with a nice woman at RI Housing. She said that tenants get 30 days notice, that's it!
With Vanessa's situation, we're not exactly sure when the 30 days would begin or have begun. The real estate company that has called her hasn't been exactly up front and has said that there is a mortgage company involved and they are the ones calling the shots.
I'm waiting for some others to return my call and hope we can get a little more info.
