Dual agency is allowed in Illinois. If a realtor shows a home (listing) where they are representing the sellers and you explain how your advertising dollars will, about 25% of the time, bring them a buyer through the listing agent. The realtor owes fiduciary responsibility to the seller but is obligated to tell the public of any latent defects in the property.

A realtor does not harm their seller if they explain to them how you will; tell them about the qualifications of the buyer but not how much a buyer is willing to pay. The seller also needs to know that should they allow you to be a dual agent that you can not tell the buyer how much you (the sellers) will accept for the home. It is also a good idea to explain how this confidentiality of personal infrmation does not go away as the home sale is completed. It last forever.

The buyer on the other hand needs to be informed of the possibility of dual agency before a realtor ever shows them a property listed by that particular realtor. If the realtor explains this up front to a potential buyer they will be a little more cautious of how they go about "negotiating" for the home. This puts the realtor, the buyer and the seller in a more favorable win-win situation.
