If an investor purchases the property and wants you out the will most likely initially try to strong arm you. If you dont move out, the will have to go through the courts and evict you.
In all likelyhood the lending institution will take back the property. You should have contact information on the papers you were served with as a tenent in the house. Contact thier attorneys and ask...... Fannie and Freddie loans have provisions for owners and tenants to stay in the properties, but the guidelines are changing all the time. You can also attend the auction to see who purchases the property.
Best of luck
