New landlord does not affect the lease (unless foreclosed on)

If the landlord sells, dies or transfers the property, the new owner is obligated to honor your lease and any other agreement you made with the original owner or management. (This is another reason to always have important agreements in writing, signed and dated.) However, if the property is foreclosed on by a bank or some other entity because the landlord did not pay the mortgage on the premises, the new owner is not obligated to honor your lease (or any other agreement), but they must allow you to stay at least 30 days from the date of the foreclosure sale as long as you do not violate any other portion of the lease and you are current on your rent. If you receive notice that your landlord is about to be foreclosed on, and someone else is demanding you pay them rent or vacate, consult an attorney because it is sometimes hard to determine who to give the rent to.
