Sub 2's and Loan Mods

[Will Edgington]

I would like to find Sellers who have completed loan modifications with attractive interest rates that are fixed. I have seen some loan mods listed in the documents of homes going to foreclosure (2% fixed for thirty years) but not all homes in foreclosure show whether or not a loan mod has occurred. I would like to purchase homes subject to these great fixed rates. Does anyone know how to find Seller's that have completed these juicy loan mods? Is there additional risk of having the loan called due on transfer because of these attractive rates?
