Does the foreclosure of the home we rent...

[daisyfacethemusic]

...constitute the landlord breaking the lease? We paid rent for all of the month, but halfway through, our landlord told us we would have 5 days to move out, because the house had been foreclosed, and the new owners want us out. The letter said we had no legal right to stay in the house, and that after 5 days, the sheriff would come in and take our belongings. He says he will refund the security deposit after we move out if there are no damages to the apt. Are we free from our lease obligations because he has broken the lease? Should we believe that he is really going to fix the damages on a house he does not own? Are we owed rent back from this month? I don't know what to do. I live in Louisiana if that helps. I mainly want to know if the house being foreclosed nullifies my lease, since it is not being transferred. Thanks!!!!!!!!!!
