*laugh* Nope. Mr. Olson may have to repay a couple thousand dollars of the commission. In the worst case scenario, he may have to pay few couple thousand dollars more, if it can be proved that he had arranged to have the house sold for less than it otherwise might have been sold. The couple don't get their house back, and in fact Olson will terminate their (subsidized) $500/month lease.
End result, the couple gets (at most) $2000-$8,000 and is homeless, and Olson gets (at worst) censured by the state real estate agent licensing board for failure to make full disclosure. There is no chance that these people will get "their" house back (since they didn't own too much of it anyway). There is also no chance that "Jim's Food Center" will be financially harmed by this story either.
Frankly, Olson sounds like the hero here, for trying to save these ungrateful wretches from being foreclosed upon, and then for renting them their house back at way below market rate. Just goes to show that no good deed goes unpunished, I suppose.
