I was shopping for a house in the Woodstock area in 2013 with Northwest Suburban Real Estate and it was a great experience. No pressure, knowledgeable agents, personable, and they found me the perfect house. I recommend them to anyone looking for a real estate agent.

I listed my Johnsburg home with Northwest Suburban Real Estate in 2019 and they sold it at a good price within 2 months. They were there every step of the way. Several years ago they helped me buy a foreclosure home in Crystal Lake and I got a great price. I rehabbed and listed it with them a few months later and made good money. After 3 transactions I can definitely say they are good at what they do

I reached out to NSRE to list my Elgin home. Brad created an amazing listing complete with professional photographs, attractive description, and a price that resulted in a cash offer in less than 48 hours. To say that I am happy would be an understatement! I highly recommend Northwest Suburban to my family, friends, and anyone who desires a smooth process!!

Sean was honest about concerns he would see in a
