How can an investor help in a foreclosure?

[Vernon Wharff]

I'm trying to better understand how a real estate investor could help a homeowner who has received a NoD under two different scenarios:

1) The homeowner has $10K in credit card debt and wants to stay in their home if they deal with an investor. The home is worth $220K and the home is appraised at $200K. He is in an ARM that has just readjusted and made the home unaffordable.

2) The homeowner has a $15K second mortgage, $150K first mortgage, and their home is appraised at $170K. The homeowner also has $15K in medical expenses. She is willing to move, but would prefer to stay in the home under any deal with an investor. She is in a 30-year fixed mortgage.

Thanks!
