Taking over loan before Foreclosure?

[Dan Ricks]

A family I know may soon be forced to foreclose due to job loss and high mortgage payments. I do care for them and I've heard of ways where I could potentially come in and join the loan? It would allow them to still live there for the time being and I could have some equity in this property. How does this work? I don't have the ability to take over the whole loan myself by the way.

What are some solutions that would 1. Allow them to still live in their home. And 2 be an investment for me in this great house/property. 

Thanks :)
