What's the catch w/ ads "Investor seeks RE mentor"?

[Eddie V.]

Edit: title should say "Investor seeks RE mentee" (not mentor)

Im looking for a side RE gig to compliment my commercial RE appraisal role I just started (doesn't pay much and no more then 40 hrs a week). Around my neighborhood I see bandit signs advertising "Local investor seeks RE mentee/trainee".  I see the same on Craigslist just slightly different language. They often say something along the lines of 5k a month part time or 10k full time.

I'm wondering what's the catch if any?  Have any of you reached out to these ads?
