Illinois requires a license to market aka wholesale more than one property per year.Are you looking to get into the wholesale game here? 

I had one were we did not get to it for a while 6 months or so it was just boarded up.. when i went to sell it wholesalers were going through it said it smelled bad.. one of them finally went down to the basement and found a corpse that had been for quite a while. scared the heck out of him..

And keep in mind private sellers and wholesalers dont help either when they wont entertain offers below ask either.

@Erica ArceCould you have a written agreement directly with the wholesaler that outlines your fee for bringing a buyer to their deal?

I entered negotiations with a wholesaler for a vacant lot.

Quote from @Jonathan Greene: Looking on websites at foreclosures is like being on a wholesalers email list.

Consider off-market sales to avoid public listings and minimize tenant disruption, using discreet marketing or a wholesale strategy.

Be different, BE GENUINE. 

Found it on Facebook marketplace through our wholesaler that had gotten the deal from the previous owner before he had passed away so purchased it as a probate sale so I was able to get it far below market value.

@Michael HayesYour profile mentions you wholesale properties and have long-term rentals.
