A real estate brokerage in Chicago is selling $1,000 discount coupons on Groupon. They are good for $1,000 cash back at closing and it's good for owner-occupants and investors. The coupons are good for one year and a total of 50 must be sold (at $25 each) for the deal to become valid. The pruchase price of the house must be over $150,000. If you invest in the Chicago area, this might be a good deal.
