 "I will never leave you stranded!"

I often receive phone calls from buyers and sellers who say their agent is not responsive or is often unavailable…that will not happen with me.  I am a full time and full service Realtor.  I work to make sure every one of my clients are Top Priority.
In the Real Estate world, agents are often busy with other clients, which means, they may not be available when your dream home becomes available.  If you are working with me, you get my full service all the time, any time…
I will always be available to show you that perfect home that just came on the market before it’s gone. 

With such important decisions to make you can be confident I will be looking out for your best interest.  I will take the stress out of buying or selling your home by guiding you every step of the way.

We could not have asked for a better experience! Mariann did a thorough job of researching the market, looking at current market vs homes sold in the area and setting our home up to market perfectly. Our home sold fast and closed in two weeks! The entire process was very streamlined and easy.

I was able to purchase my home with the expertise of Mariann Egelhoff. She goes above and beyond what's required of her. She's always on time, organized and rest assured, she's an expert, very successful in her field. I've recommended her to several people and they have been so pleased - nothing but high regards about her relationship with them, how she helped them through the process. Buying or selling a home is a challenge but you can totally depend on Mariann. If you listen to her, trust her - you can bet she will get the job done. You can depend on her to answer when you call, email or text her with a question. Mariann is there - FOR YOU. If I were provided 10 stars, I would give her a 10 for excellence. She's honest and comfortable to work with, explains everything in detail. I'm African American, she's Caucasian - NOT A PROBLEM AT ALL. I've experience racism throughout my life but not with Mariann. She's a pleasure to work with and very patient. She's knows her stuff!!!! I would highly recommend her to anyone and I mean that from my heart.
