Tell Us Your Story

I met Mark as I was calling on one of the properties he listed.

That property ended up not working for my family, however my interaction with Mark was so pleasant, I wanted to work with him on my home search. Mark is professional, patient, and has a great sense of humor. Even my toddler still asks about him. He doesn't try to push you into anything just to make the sale and he truly cared about my family's needs. Although he led us through the process, every decision was discussed and agreed upon before moving forward. He's very easy to contact and if you can't reach him immediately, he responds promptly. Mark was everything that we needed in a Real Estate Professional and he is who I will go to first should the need arise again.

He answered all of our questions and was very knowledgeable. I feel we have gained a new friend in our community and would recommend his services to friends and family.

David and Alicia Maxwell

Mark got us an offer on our house within 4 days of our listing with him.

The offer we got was for the full asking price, but was contingent on the sale of our buyers house. The sale of the buyer's house was quite a process that lasted several months, pushing the sale of our house back several months. However, Mark personally handled all the issues that came up in a timely manner and kept us aprised every step of the way. His service was EXCELLENT and he was great to work with. In fact, we're still working with him - he has found us our new house and we're currently in escrow. We would recommend Mark to anyone interested in buying or selling a home. Thanks Mark!!!

Clay & Susan McDonnell

Mark Wisterman was my realtor when I bought my home.

Before choosing my home Mark showed me many, many houses. He always made himself available to me if I wanted to see a house. We looked at close to 20 houses. Including houses located from Kelly Ridge across Oroville and Thermalito to Biggs. I purchased my home in November and now months later he is still assisting me with home warrantee/pest issues. I would recommend Mark to anyone who wants a realtor that really cares about and goes out of his way for his customers. Thanks,Gavin

Gavin Zarate- Home Buyer

Mark is a great asset to our community.

I bought and sold my home through him. He was always available when I called for clarification on something. He’s so great that he has become our family realtor. My sister and grandparents chose to work with him and he has always came through! He has integrity (which is rare these days) and is knowledgeable about our market. I strongly recommend working with him.

Bri Medford

Mark is an outstanding realtor who, with a sense of humor, professionally and quickly worked through a myriad of difficult issues to deftly sell my home.

I live on the east coast and therefore was unable to handle any of the issues in person. Mark was always just a phone call away to answer my numerous questions and to keep me apprised of the status of the selling process. It was a true pleasure working with Mark. and I highly recommend his services to anyone considering selling their home and/or buying a new home. Thanks Mark for all of your excellence assistance!!!!!

Shirley B.

Hello all, just want to take a moment to say a few words about my first home purchase.

As i am sure it is in most cases it was very stressful and nerve racking. Not only did i have very little knowledge about the whole process but it is great responsibility. From day one my realtor has been a very big help. Through all the bumps along the way Mark was very informal and helped make everything as smooth as possible. Mark is very quick to return your call and never makes you feel like a bother. He is very hard working and great at what he does. I would strongly recommend Mark Wisterman to anyone and everyone interested in buying a home.

Mark Wisterman is an outstanding broker and is one of Oroville's greatest assets.

In concert with Renee Jones of Commerce Home Mtg., Mark helped us through a deal which had some complications; he adeptly guided us through these difficulties. I believe Mark possesses the perfect combination of intelligence and personality which gives him the ability to make anyone feel at ease in what is a very difficult and stressful process for most. Mark is both friendly and professional, and has a vast wealth of real estate knowledge. I am lifelong client of Mark's...whether he likes it or not. :) Thank you, Mark.

E. Heitz-Seller

Mark is a very professional but very personable person.

He did a great job selling our property. The photos he took brought out its beauty. I would recommend him and have done so.

Danny Raynor

In 2014, my elderly parents developed health problems and needed to sell their property in Bangor Ca.

I was referred to Mark Wisterman by a local Realtor and I was so glad I was. Mark was able to realistically assess the value of the property and then place the property on the market for sale quickly. My parents had an offer within two weeks. The sale finalized within several months in the asking price range of my parents. Thanks to Mark's skill and professionalism, I found selling my parent's property much easier then my family ever anticipated. I would strongly recommend Mark Wisterman to anyone interested in selling their property in the Oroville area.

James F. Richardson

We used Mark Wisterman's services as a realtor and were very impressed.

He always answered our calls in a timely manner and knew the answers as well. He was obviously very knowledgeable about the Oroville market and had suggestions based upon this knowledge. We particularly liked that he was computer savvy and used this tool in all aspects of his business; especially so in the marketing process. We would highly recommend him as a realtor, particularly in the Oroville market.

maynard and dorothy nichols

Mark was a true professional.

He helped me sell my fathers home in CA when I lived in MA. He handled a lot of things I could not due to the distance. For example, he coordinated repairs that came up during inspection. He also walked me through on where to negotiate on the offers I had received. Well worth the fee he earned from selling the property.

Carl I

What can I say?

I completed my purchase of a home through my brother's trust for his daughter with only one trip from the Monterey Bay Area to meet Mark in Oroville. He immediately inspires trust and confidence. He only showed me homes that fit my criteria and price range. He returned my many calls and emails promptly. He understood the importance of finding the perfect fit for my niece, the trust, and me, as trustee, and sensitivity of my particular circumstance. He held my hand through the process of Esign, as I am not a computer whiz, and completed tasks that I couldn't, being hundreds of mile away, such as walk-through, overseeing repairs, etc. a truly spectacular experience working with a truly spectacular agent.

Karen Friedman

Mark Wisterman has always gone the extra miles when needed to either help us acquire or sell our properties.

I highly recommend Mark for all your real estate needs- he is professional, honest, respectful at all times, and just an all around wonderful human !

My husband and I would highly recommend Mark Wisterman to family or friends or anyone who will be selling their property.

Mark is a very knowledgeable, personable, honest and forthright realtor and a truly kind man. We had many laughs together. He worked tirelessly to help fix issues that came up during our home sale. He stands up for his clients and is very professional. He even spent several hours of his personal time on a Saturday to come to our home and resolve misunderstandings and made certain we were clear about all of the choices available to our situation. He became a friend to us.

aresa floyd-Coderre

Mark has sold two properties for us and has made everything smooth as can be.

..we really appreciate it! Thank you Mark! Charlie, Judy and Jana

Charles and Judy Jensen

Mark worked with me for nearly a year while I looked for the perfect house.

He was more then patient with my picky nature and adapted his house searching to my needs. He was accessible any time I would text, email or call. Mark went over the call of duty to find and close my most perfect house. Thank you Mark! I love my home.

Charles Tracy

Mark Wisterman is the best we’ve worked with!

He is kind, professional, and very knowledgeable! He sold our first home and most recently, our property in such short periods of time. I would not go to anyone else! We highly recommend Mark!

Yvonne Katsuyama

Selling a house with Mark Wisterman was one of the most positive experiences of my life.

He helped me price our house perfectly so it would sell in a reasonable amount of time. Since I live out of town I thought it would be a nightmare having to take trips to Oroville to sign papers, etc. The process was made simple through "e-signature" of which I had no prior knowledge. It streamlined the sale and took the stress off by not having to make those trips. Mark took a difficult situation and made a positive outcome. He made sure all the "i's" were dotted and all the "t's" were crossed so that nothing could hamper a sale. Not only did he sell the house in record time, but also over asking! What more could I ask for. Mark is pleasant with a good sense of humor. I would not hesitate to recommend him and have already told a realtor friend that if she gets any clients looking in the Oroville area, to send them to Mark.

Mary Fox

We loved working with Mark.

He is very friendly and easy to talk to. He was always very accommodating and wonderful at helping us navigate which houses fit our loan and price range. He has plenty of wisdom and insight to share and is obviously extremely knowledgeable and capable when it comes to the housing market. We recommend Mark wholeheartedly and would definitely contact him again if we were to buy another home!

Jonathan and Ashley Dow

Selling a house for the first time can be scary.

Thank goodness we had Mark. He was available at all times to answer questions and assure the process was as smooth as possible.

Jeff Uecker

Mark is a true professional.

Extremely dedicated to every client. He is always available and agressively solves any problems. Our house was listed, sold in 3 days at full price and closed in 30 days without issue.

Leonard Newton

For several years now, Charlie & I had been dropping by to see Mark and asking a question or two about the home sales market in Oroville ; never really sure that we wanted to move here locally or away from the area totally.

He would chat with us each time and somehow, I think he realized that we weren't really quite ready. Patient; that's what I liked about Mark. When we noticed a home we might be interested in on the market, Mark made time to show it to us that same day and we made an offer the next day. Now the big job of selling our current home . . .the listing went up and he was able to obtain 3 offers that very week, one of which we accepted at above our asking price. His professional manner and ability to guide us through the successful closing of both homes made the ordeal totally painless for us. I most heartily recommend Mark to anyone who is either buying or selling a home. His business ethics are above reproach and I feel confident that we chose the very best realtor for both transactions.

Judy Jensen

Mark was a joy to work with having the knowledge of a true professional.

Making the sale of our property for top dollar in a timely matter. We were glad he was working for us with great ideas and good suggestions.

Patrick McKinney

Before listing our home, we met with Mark at his office.

He prepared for us a strategic pricing analysis on the value of our home. This comprehensive booklet compared our home with others and helped us to decide on the listing price. Mark guided us through the process of selling our home: how to prepare the house for inspections, respond to multiple offers, even helping us learn how to sign paperwork on the computer. Mark did a fabulous job on the multiple sales listing which went on the internet right away. The photos were great, the text honest and appealing, attracting buyers. The journey was swift, the house sold and was in escrow within three weeks. We agree, Mark Wisterman is trustworthy, always available, a true professional and lots of fun to work with.

Philip and Mary Hall

We recently completed a sale with the excellent efforts of Mark Wisterman.

We purchased the home with Fannie Mae as the seller and, of course, dealing with a government agency always presents unique problems. Mark's experience and patience helped to exepedite the closing, which was done in record time. As a former real estate agent myself, I appreciated his constant communication and his "we can get it done" attitude. I would certainly recommend Mark for all of your real estate needs and be able to feel confident that he will represent you in a professional and caring manner.

"I have now worked with Mark from both sides...the purchase of a home, and the sale of a home. He does not skip a beat anywhere in the processes. He is thorough, anticipates and mitigates all possible issues. He is responsive in a timely manner, explains every step along the way, and relieved me of all the pressures surrounding both the purchase of a home, and the sale of a home. I can not recommend him in glowing enough terms! You won’t make a mistake by choosing him to represent you on either side of the table."
