"We could not have asked for a better partner to navigate the home buying process for the first time! Mark's experience, extensive knowledge of the area, guidance on what to look out for in homes and key considerations when it came to home inspection items were invaluable to us as we were making a decision. Not only does he bring 39+ years of experience to the table, but he also is an extremely dedicated professional - he spent hours with us during our home search - coming prepared with research on all of the properties we visited to make it as easy as possible for us to consider the options. Once we had decided on a property, he went above and beyond to answer all of the questions we had - countless texts, emails and phone calls were exchanged to ensure every detail had been addressed. We felt completely comfortable putting our trust in him to negotiate on our behalf, and we were very pleased with the final terms of the deal. He was there to support us every step of the way."

"We were referred to Mark when we were buying a condo in 2014. As first time home buyers he was very informative and helpful. 3 years later, ahead of schedule we decided to sell our condo and buy a house. Mark was again very helpful in coordinating and assisting us in coordinating the contingent sale and purchase. Mark was again very knowledgeable about all the neighborhoods we were interested and helped us a lot to make a great final decision. He has also given us great contacts and advice on home improvements. He was accommodating to our work schedules and always prompt. When we closed our home purchase he sent us pizza and beer for our friends and family moving crew, a great housewarming gift. We would highly recommend working with Mark Kloss!"

"I had the pleasure of working w/Mark when he handled the sale of my home. Mark came highly recommended to me by some trusted friends but I interviewed several Realtors to make sure that Mark was the best fit for me. The home that I sold was a bit unusual -- all the Realtors that I spoke with told me that it was a challenging house to price. Mark and I agreed quickly on a listing price and then the magic happened. Before the house was truly "listed" Mark told me that he knew of a buyer that was looking for a home similar to mine. This buyer came in , loved my home and the whole deal was negotiated quickly and painlessly. I never had to go through the headache of home showings, staging, open houses, etc. Mark made the buyer - seller connection via his network. Additionally, Mark has resources to assist in all areas of real estate transactions. He recommended my mover and they were top notch. I cannot recommend Mark more highly!"

"Mark helped my wife Barb & I through the entire process. He staged the house for us, posted Pictures on line and they were excellent! Our house sold in no time at all! Best part of all, he even showed up because it was snowing on moving day and laid down carboard throughout the house so the movers wouldn't get the house wet & snowy. Then when we moved into the new house ( which he also orchestrated) he did the same thing when we moved in. If you want the true pro to sell and help you find your next house, Mark Kloss is the best!!!!!!"

  -Matt & Barb B, Client

"Mark's knowledge and experience is exceptional. Because of this, he was able to handle any situation that arrived in the selling of our home. He is extremely diligent and hard working and was always available to answer any questions that we might have. From the beautiful professional photos of our home that he had done to the wording of the listing, he was able to generate interest from prospective buyers. Mark made the whole process of selling our home a positive experience and we would highly recommend him."

  -Lou & Kathy P, Client

"Mark Kloss was very courteous and professional throughout the whole sales transaction. He is the best realtor I have ever worked with in my 4 house sales. Mark's staging and photo team did an excellent job in displaying the house. I would recommend Mark Kloss to anybody interesting in selling or buying a home or condo."

  -Dan V., Client

"Great Realtor! Knows his stuff, Marks 39+ years experience in real estate shows! His experience in the Chicagoland area is great, helpful on what renovations to do first! He was very helpful from beginning to end on the sale."

  -S. Berichon, Client

"Mark Kloss is the BEST realtor to work with anywhere in the world. By far, he's the person you may count on to help you sell your home and buy a home and do it all right...AND he's efficient, caring, thoughtful and protects his customers and clients from areas that some realtors don't seem to understand. I met Mark watching him sell other homes near my home years ago that were difficult to sell, old homes beautiful yet difficult to get buyers in. Once I called Mark, my home that had been on the market with another realtor for a LONG time--he sold quickly in a short period of time. He just focuses and does the job. He makes it simple and pleasant...a rare bird he is. He's helped us in a variety of communities and is always top notch! The BEST realtor anywhere!"

  -Mary Felish, Client

"Mark is great. He's personable, knowledgeable and a professional. On more than one occasion he walked us through properties that we liked but weren't sold on and talked to us frankly about the positives and negatives on the property from the mundane like driveway access onto a busy road to potential remodel ideas. We had a great experience with him."

  -Will & Jessica, Client

"Mark worked hard to get our home sold, was very committed and realistic about pricing. He knows his market and can read his buyers. Great work ethic. I highly recommend Mark Kloss!"
