Holy River North knowledge. I was specifically looking in River North and found Jon Perlman through a Google search. He found me the perfect condo extremely fast, negotiated the price down, and helped me closed on it in record time. Everyone says buying a home is stressful, well, it sure helps when you never second guess the property your buying. The most amazing thing is, he predicted a double digit rise in the price of the condos in my building, and it happen over the summer. Jon knows value. I'll call ya crazy if you use anyone else.
