Surprises can be fun at parties, but never in real estate. I’ve focused on details my entire professional life, because the fine print is so important. A seemingly small detail can unravel a transaction.

But there’s the big picture, too. For me, real estate isn’t about buying or selling a home. It’s about helping people realize a life change. I grew up in the business and saw first-hand the human side of real estate. My mother ran a brokerage in New York, and I held a sales license there.

After a career in corporate finance—including time as a fraud investigator and forensic accountant (how’s that for watching the details?)—I relocated to Tucson with Cathleen, my wife and business partner. We received our Arizona sales licenses at the same time and started with Long Realty on the same day.

We tell people we’re not natives, but we got here as fast as we could. We also say we love the sunshine, because you don’t have to shovel it.

My interest in astrophotography is a perfect metaphor for how I approach real estate. To take photographs that bring out the faint details of galaxies and nebula, you need both a close attention to detail and a clear view of the big picture. Leave out one or the other and all you’ll get is a snapshot. In a real estate transaction, ignoring details or forgetting the client’s perspective will result in a disappointed client, a rough transaction, or both.

People who know me say I’m honest and very focused. I agree—honesty and integrity are very important to me. Cathleen and I always tell the truth to every client. And no surprises.

Client Reviews

"We used Mike and Cathy DeSantis as our real-estate agents recently to buy our new home and they were great.  As we had just move to Tucson they helped us feel out the different areas and were very patient with our many, many questions. Ultimately they took note of our likes and dislikes and found us the perfect home.  I don't think they could have been more helpful with the closing and inspections either!"

I would like to take this opportunity to thank Mike and Cathleen DeSantis!  They are wonderful, diligent, responsive, and yet very patient. They obviously take great pride in what they do as real estate agents; both are very professional yet personable. I could not imagine my first home buying experience going any smoother than it did, largely due to the DeSantis team!  Thank you both so very much!

We would like to thank Mike and Cathleen Desantis for giving us a wonderful experience while selling our Townhome. The photographs Mike produced of our property were beyond good.  The consultations and advise from both Mike and Cathleen were excellent.  From beginning to end they were there for us. If or when we purchase another home in Tucson we would use Long Realty and most definitely request Mike and Cathleen as our agents.  We would recommend  working with them to anyone moving here.  Over the years we have built and sold homes numerous times and can say without a doubt that Mike and Cathleen gave us the best experience without the stress usually associated with selling a property.  They were there for us 24/7. Thank you so very much Mike and Cathleen!

Mike an Cathleen worked with us to find and sell a home. They are very professional, a joy to work with and always had our best interest at heart. They were in constant communication which kept us at ease when there were changes. They are the best and I would recommend them to anyone who is buying or selling their home.

As a first time home buyer I wasn’t sure what to expect. Micheal and Cathleen were great about explaining how the whole process worked every step of the way. They explained all my options to me. They were never pushy on any property we looked at. Looking at comps could have been confusing but they were sure to break them down and help me decide how much the property was worth so I wouldn’t over pay. They were able to show me properties at a drop of a hat and were very flexible. Once I had an accepted offer they were very helpful at outlining what I needed to do next and were always available to answer questions. They really made my home buying experience easy.


Loved working with Mike and Cathleen DeSantis. They went above and beyond to find our new Townhome and sell our home. We have worked with them in the past and will work with them if the need arises again. Beautiful agents with the utmost with helping us. Five stars for sure! Gary and Linda Thate

Cathleen and Michael DeSantis are excellent agents. We were wanting to purchase a home in Arizona while we still lived in Illinois. We communicated back and forth by phone and email about what we were looking for and what was available. On our first day out with the agents in person we purchased a lot and floor plan to be built for us. What was very evident was that they really listened to us and found a perfect reflection of that. They remained very communicative during the building process and made sure we understood the process. We had never had a home built for us, much less having it done while we lived very far away. The whole process from purchase, building and closing actually seemed easy. We never felt like we were not in the loop. We could not be happier now that we have closed on our new home. BEST. AGENTS. EVER.
