When people go through foreclosure, foreclosures help is good at making them feel reassured like they are not alone. You might offer to help some of them out financially if you are able to, if not, just provide as much moral support as possible.
Offer advice as to how to approach the lender with a well defined, written plan, to lower mortgage payments for an established period of time. Encourage him/her to seek possible ways to avoid foreclosure and offer to do research for them, either via Internet or phone. Foreclosure is a very devastating situation for anyone.
Moral support from family and friends is of great importance at this time.
