Our company, Select Properties, when formed in 2002, was created to keep our local market. . . well. . . local. St. Louis is our hometown. We grew up here. We live here. We work here. Who knows, you and I may even be neighbors.

The thing is, I know St. Louis and all the surrounding counties. I know its neighborhoods – we go to the Hill for Italian, hit the Loop for people watching and know Dogtown is the place to be on St. Patty’s day.   We were here when the Arena went down and can remember when Wildwood was actually country.

We know its quirks. Our favorite summer treat is handed to us upside down too. We can correctly (ahem or should I say incorrectly) say Gravois, Chouteau and Spoede.

But most of all, I know its market . . . because I live in the market, specifically St. Charles County.  Our decisions are made based on the same trends that your family experiences right down the street.


Select Properties, formed in 2002, now has 10 offices in the St. Louis Metropolitan area, which includes 2 offices in St. Charles County, 1 office in Lincoln and 1 office in Jefferson County… representing over 550 agents. My Office ranks #1 in the entire company.  We're ranked #26 in the Berkshire Hathaway HomeServices national network, ranked #2 in the St. Louis Business Journal Book of Lists of Top Real Estate firms, #2 in real estate transactions recorded by the St. Louis Association of Realtors and in the top 20% of real estate firms nationwide. We rank as the #1 locally-owned real estate firm in St. Louis.   Maryann Vitale, Deb Colburn and Angie Ignatowski share ownership of the company, ranking #18 in Women Owned Companies by the St. Louis Business Journal.

Our Mission, Our Vision, Our Values

To provide the highest quality real estate brokerage service to my clients and customers and to be recognized in the community for high standards and ethics.

My guiding principle is simply doing the right thing every day to earn the trust and respect of each other, my clients and customers.

Ask Mark Hunstein


When my mom passed and we knew it would be a matter of time for my dad to go into assisted living. I told my brothers that we have to use mark to help us sell my parents villa. They agreed and we listed to everything mark told us to do and it sold the first day it was listed with multiple offers. This is the second time using mark and let me tell you he is awesome. He makes you feel so comfortable with the entire process. He is always there to answer any questions and even help getting the property ready for the market. My dad couldn't be more happier with the job mark did to help him out. I will always reccomend mark and his company to any of my friends to sell or buy a house. Best agent and company out there.

Mark provided excellent assistance to us during our home search. He was very knowledgeable about the area where we were looking to purchase. Mark worked very hard to find homes for us to view that met our needs and requirements, and that were in our price range. Mark provided exceptional customer service to us, and we would be very happy to use him again for any home acquisition needs!

- Peter S

Mark knew what we were looking for and found several homes for us to see. The house we bought was perfect for our needs. He was kind, helpful and very knowledgeable.

- Jean S

Mark was thorough, responsive and informative as he guided us through this process. He consistently demonstrated strong industry knowledge and strenuously advocated for us to ensure the seller/agent followed through on commitments to address issues that arose during inspection. I would definitely recommend Mark to others interested in selling or purchasing a home.

- John S

Mark made himself available whenever we needed him. He sent us new listings in our area of interest as soon as they became available. His expertise in things to look for and watch-out for was very welcome. Mark is a great representative of your company and a pleasure to work with
