What strategy is this investor using?

[Nathan Habben]

I recently saw on a real estate investor's website the following claim:
"The low equity situation is the most common we run across.
You don't have to give away your equity
to a real estate agent, no matter how small it is!
We purchase homes with little equity and in many cases are able to return much of that hard earned equity to the homeowner who deserves it the most. "

This is from a lead generation site that is looking for motivated sellers. I assumed they would have to be talking about doing a short sale given that they are targeting those with little or no equity. But then how are they sometimes able to "return much of that hard earned equity to the homeowner who deserves it the most."

If it is a short sale, I haven't seen the claim made that equity would be returned to you, since I didn't think the seller was allowed to get any money out of a short sale.

Any ideas?
