Bill Biros and his Team did a great job in this tough buyers market in Evergreen Park! Bill not just on the listing but in the sale advice critical to me making the decisions on property inclusive of improvements to highlight the features of the home. He also was integral and quick to move on our cash purchase of a condo and orchestrated that purchase to coincide within 10 days of the sale of the Utica Property. I would recommend Bill and his team to everyone. He will get the job done noting that the family home is not just a building but a home filled with memories.

Bill Biros is an Evergreen Park Relator who knows the area, the people and the flavor of this family oriented community.

A tough climate due to a Buyers market in Evergreen Park. Assisted me through the entire process and found the right price and the right family to acquire our HOME.

Professional, considerate, understanding yet guides you through the process and assists in ensuring the home looks it's best to prospective buyers.

The Open House did the trick. Who would have guessed.

'I have known Mr Biros for over 50 years and know him to be of stellar character and trust him with my financial dealings as he would put my interests above his own. I have known Ms Molnar for over 25 years and felt the same about her. I have dealt with Ms Molnar in the past, and have referred my clients to her when they were in need of a Realtor. I trusted that Ms Molnar would always do her best for my clients (I'm a local CPA).

When it came down to pricing our property, we had frank discussions with Ms Molnar and we felt confident after reviewing the comps and her approach to our listing, that she was representing us well.

We are very pleased with our selection and will continue to recommend Mr Biros and Ms Molnar to our friends and clients.

The support staff represent the high standards of Biros Realtors.

I couldn't be more pleased.

Ms Molnar kept us apprised of every aspect in the progress of our sale - she provided us the contract on the day the proposal was made and facilitated the execution of the contract. Berkshire Hathaway is fortunate to have people the caliber of Ms Molnar and Mr Biros as associates.'

Before my aunt passed away she recommended that I contact Berkshire Hathaway Home Services Biros Real Estate to sell her house because she knew William Biros (Bill) and his family from the neighborhood. From the beginning Bill and everyone else that I dealt with really went above and beyond what I have ever experienced with any other realtor that I've worked with.

Knowing that I was unfamilar with the area Bill was able to put me in touch with the various contractors that I needed to get the house into a saleable condition. All of the contractors that he recommended were top notch and did an outstanding job at renovating the house. I like to think that when everything was completed the house looked just like what my aunt had always told me that she wanted done while she was alive but didn't have time to do. Bill was also able to recommend an outstanding Real Estate attorney when the firm that I had planned on using fell through at the last minute (and this is coming from someone who normally doesn't trust lawyers).

Once the work was completed on the house and the job of the actual sale started everything went flawlessly. I was kept up to date daily with any showings and potential buyer feedback and Bill was able to secure a firm offer within a week of the house going on sale.

The final closing was yesterday and even that normally stressful situation was painless.

So, from first contact to the final closing I feel that WIlliam Biros and Berkshire Hathaway Home Services Biros Real Estate were with me every step of the way and I would recommend them with absolutely no reservations.

Bill Biros is amazing would never deal with anyone else!!

- Julie Smalzer, Chicago, IL

As a real estate developer who has bought/sold over 100 properties, I have used Bill Biros as one of my primary agents. Both in the purchase and sale of our homes. Bill is a true professional and epitomizes what a full service broker should be. I know if Bill says it then you can take it to the bank. Both on the acquisition side on what we should pay for a property and on the sale side on what the property should sell for. Currently we have three (3) listings with Bill and are looking for to many more.

- Tom O'Neill

We knew from previous experience that he is competent and trustworthy and would help us get the best buyer for our house.

We were selling my mother's house since she had just passed away, so , Bill was very patient with us and waited to,start the process until we were ready. He was very compassionate since this was a very difficult time for us. He always kept us updated with all the showings and the results of the showings. And, we trusted his recommendations to find a buyer for the right price. It was an excellent experience for us. Thank you !
