My home that I had Joint tenancy with survivorship was foreclosed. I was never contacted about foreclosure or opportunity to buy.

The security deed and promissory note which you executed at the time of the loan would govern what notice requirements were required to be given.  I am assuming that you no longer live at the property.  Some type of default/demand notice would have been sent to the address as provided for in the loan documents. This is usually the property address.  There is no requirement that the lender locate you.
