About Alexander Realty

Dedicated to the Real Estate Industry for over 20 years, Alexander Realty opened its doors and very quickly became one of the leading REO firms in the St. Louis Metropolitan area; trusted by nationwide banks and asset companies to handle their assets.  The vision for the firm is to accelerate quality growth in communities across our area of the state where the local residents, community leaders, and business owners benefit from the professionalism, research, and expertise that Alexander Realty agents provide. With the changing market, Alexander Realty has also expanded and focuses on residential sales, all while still handling bank owned, short sales, land, and commercial real estate.

Alexander Realty is a local business specializing in running an independent company without the restrictions large corporations can place on agents that affect buyers and sellers during the purchase or sale of their property. As residential specialists, Alexander Realty's agents have developed a completely unique marketing system for their clients.

Alexander Realty is committed to improving the quality of life and self-sufficiency in the St. Charles area and surrounding communities.  The firm’s licensees and staff consistently educate buyers and sellers issues important to their housing concerns, including affordable housing and sustainable homeownership, while making available all the full-service options Alexander Realty provides through their educational programs for people of all ages and economic status.

Alexander Realty’s office is located on Main Street in St. Charles, where there is an active and fun-loving “vibe,” a sense of community, and where everyone feels welcome.

About the Founders

Renee and Mark Ottinger, broker and owners of Alexander Realty, began their real estate company with no prior background in the real estate business except for their own experience with investing in lower-end properties. The expansion of their immediate family and changes to their employment status compelled the couple to take a big risk and open up their own brokerage.

The company started with REOs almost immediately. Renee and Mark were able to think “outside of the box” because they had never learned bad practices; therefore, they systemized the REO process. The training and work ethic of the firm led to Alexander Realty becoming the #1 REO brokerage in the greater St. Louis area market.

Alexander Realty’s agents are considered as part of Renee and Mark’s own family and the couple takes responsibility to be sure the agents produce a steady income by providing to each of them every tool available to be successful at what they do.

At the foundation of their success is the fact that Renee and Mark capitalize on their different strengths and individual leadership roles. Renee is the creative mind, providing organization, training, and motivational sessions. Mark is the problem-solver, the negotiator, and the voice of practicality. Together, Renee and Mark both contribute to the success of their agents offering one-on-one assistance to help with individual situations, something that is available every day with Mark and Renee both being in the office. 

Alexander Realty is committed to providing the best service to clients by continuing to stay on the cutting edge of today’s markets.  They will meet all of the future requirements of their clients and continuously improve upon the success they have achieved thus far.
