Nobody Knows Homes Better

We had the pleasure of working with Mike Ertmer in selling our home and finding us a new one. He was very professional and was detailed in explaining how the market was doing so we could feel comfortable selling our house at the right price. He listened intently to what we were looking for in a new home and he was very patient with our many questions. He made sure he was always available to us if we had any concerns or more questions. He was very determined to sell our house and to find us a new one with marketing and networking with other agents. He walked along side us from start to finish making sure everything went smoothly.

Excellent experience selling my home with Mike Ertmer. I interviewed 4 realtors and Mike stood out as very professional and extremely knowledgeable of our local market. He did a beautiful job of making sure I knew the “game plan” and always followed through with every aspect of the sale from listing to closing. Mike was very fast to respond to questions and communication was always easy. He described the buyer that would want to purchase my property and he was spot on. He seems to have great insight and that was a plus! I HIGHLY RECOMMEND Mike when looking for the best!

We had a fantastic experience working with Mike Ertmer as our real estate agent. From start to finish, Mike was incredibly responsive—always quick to answer any questions we had, whether it was about properties we were exploring or the home we ultimately made an offer on. He was by our side every step of the way, making the entire process smooth and stress-free. Mike went above and beyond by not only helping us find a great home but also sharing valuable insights about country living. He gave us excellent local recommendations—from restaurants and plumbers to carpenters and more. His knowledge of the area was a huge asset, and it made us feel confi...

If you need a realtor anywhere in the Green Lake area - Call Mike Ertmer! I was the buyer on a property he had listed - when I say Mike went above and beyond, I mean it! He went out to the house for me a couple of times and when closing day was 90+ degrees, he actually helped me put in a window air conditioner. Literally white glove service and someone who I don't hesitate to recommend. Way to go Mike - I will definitely keep referring you to people!

Our experience working with Mike Ertmer was absolutely outstanding! He skillfully helped us navigate both selling our existing home and purchasing a new one with remarkable efficiency and professionalism. The results speak for themselves- our house sold immediately! What impressed us most was how seamlessly he coordinated the entire process. Mike was patient, always available and a pleasure to work with. His expertise and positive attitude made the whole experience enjoyable . I would recommend him to anyone looking to buy or sell a property.

Thanks to Emily Bonfiglio's savvy negotiation skills, we were able to get a great deal on our purchase our home for a fantastic price .We wholeheartedly recommend Emily to anyone looking for an agent who is knowledgeable, dedicated, and genuinely cares about their clients' best interests.

Jeff is absolutely the Very Best! Great communication, super professional, he had an entire plan and roadmap - He exceeded every possible expectation we had. Highly, highly recommended.

Jeff did a great job selling our lake house! For higher end property he's definitely the "go to" in Green lake! Would definitely work with him again and not hesitate to refer to friends and family.

Sarah Loberg is the best. I’ve worked with prominent brokers representing Fortune 50 corporations in Global markets and Sarah is as good as it gets. She’s smart, very knowledgeable, ethical and no one works harder. Sarah creates enormous value for her clients.

Bianca is very passionate about her profession. She is tough and great to work with. I recommend her highly!

Sarah Loberg is amazing! If you need a realtor, she's the best! And our house sold quickly! Thank you, Sarah!

Great selection, helpful staff.

Great people, easy to work with. Quick replies. Made selling my home quick and easy.

Wonderful, knowledgeable, hard working agents.

We had a great experience working with Mike Ertmer when buying a house recently on Green Lake. Mike was very attentive, thorough and knowledgeable. We would highly recommend Mike and the entire staff at Special Properties.

Great staff that is extremely friendly.

Mike Ertmer did an excellent job helping us find and close the deal on our dream property. He was very knowledgeable about the area, guided us effortlessly through the process and was very responsive!

We had Sarah list and sell our home at a time when there were many similar homes for sale, and a buyer's market (2015). After a couple of months, she had an open house and sold the home. Then four years later (2019), we listed a lot (with a free-standing storage garage on it) through her, and it was sold within a month or two. She is very attentive to detail, responsive, and thoroughly enjoyable to work with.

The folks at SP do a great job. They are reliable, responsive, and take responsibility on behalf of their clients to get the job done. We were very happy with the service and flexibility they offered in order to find us the perfect property.

Working with Mike was great! Definitely recommend as he sold our lot the first day! Will hopefully get a chance to work with him in the future!

This company is as good as it gets. Friendly and helpful, and willing to go the extra mile to get your property sold!

Buying a home was never so easy!

Mike Ertmer is a fantastic choice for a realtor! First, I am also a realtor in another state and I was looking for a home in the area. He is incredibly genuine, has vast knowledge, but mostly, truly cares about his clients and their best interest! I’ve dealt with a lot of agents that only care about the money and he is not one of them! You’re in good hands with this one.
