"Sold a Townhouse home in 2019 in Palatine, IL
I am so glad I trusted Helen to sell our townhouse! She is the most knowledgeable and cooperative realtor I have ever met! She guided us throughout the whole journey (and it was not an easy one given the situation that our townhouse was a rental property.) She sold it in 3 days!! Thank you for everything!!

"Sold a Single Family home in 2020 in Inverness, IL.
Helen was FANTASTIC to work with. She provided great feedback and helped me get contractors in to do the needed work prior to listing the house. I did all the work she suggested and had 2 offers before my house was even listed on the MLS! I would not hesitate to recommend Helen! She was EXCELLENT!
