Approaching a homeowner in foreclosure...

[Shane Sams]

So I have found a great deal.  It's a home in great shape, brick, worth probably 90K but foreclosure has started (according to zillow and my local realtor buddy).

The people are still in it and nothing has changed at the PVA, it still says the owner's name.

What is the best way to approach this homeowner?

Should I just knock on the door and say "hey, saw foreclosure on your house listing, let's talk!"

Should I ask about a shortsale?  

Should I explain I can help as an investor, maybe save them from foreclosure?  

Or should I just wait it out and see if they get evicted and come in after the bank takes it over?
