About Our Agents

Here at Simply Smart Realty Group we pride ourselves for being honest. We will NOT sell you a house, just to sell you a house. We will make sure it is the right fit for you!  We view our customers and clients as people looking to make one of  the biggest decisions of their lives.  Whether is it through the excitement of purchasing a home, the mixed emotions of selling, or looking for a beneficial investment; we will give 100% of our attention to helping you.

 Unlike most Real Estate Agents today, WE WILL NEVER view you as just a paycheck!

Besides being a Realtor, I have worked in Mortgage and Title. I understand all aspects of what you need to get a loan, get the home, and get the title.  My husband and I were married in 2001 and we have 2 kids.  I started Simply Smart in 2013 with the vision of giving sellers financial options when it comes to selling a home.  The process doesn't change, so why should one pay more than another.

We worked with Stephaine Ziemann when we recently sold our home. She was always available for a quick question and solid advice. Very knowledgeable about the real estate business. We trusted her input and expertise. The buyers also didn't use an agent so with neither side represented in the traditional sense, partnering with Stephanie helped us navigate the process, stay on track with our timelines and get to the closing table effectively. Stephanie also gave us names of companies for estimates on repairs needed. I would recommend Stephanie. Flat fee brokers are the way to go. Very fair fees and it allows for competitive pricing of homes without having to take into account a potential 6% extra costs to selling a home. Gwyn Garner
Stephanie was easy to work with and ended up making me $28,000 more than I thought I would. "Thank You", Stephanie! Jace Wainwright
