Looking for old home study course! Please help!

[David Braut]

I used to own a few home, study courses by Peter Conti, and David Finkel. I somehow lost a couple of them during a move and would like to know how to find these old gems again. Does anybody know if they are still for sale or if there are any copies still floating around out there? One of the courses is called: 

How to Find, Close, and Sell Properties Using the Existing Financing” course by Peter Conti and David Finkel

Another one was on investing in foreclosures. 

Any help on finding an old copy or new one to buy is greatly appreciated!
