Guillaume Derouet - Testimonials

Tell Us Your Story

I am a first-time property buyer.

Not only that, I am Australian and have been residing in Australia for the duration of the somewhat lengthy purchasing process which, I might add, was only lengthy because a co-op was involved and my overseas status complicated matters. Throughout all of this, Guillaume was my guide, my guru and my "go-to" guy. He negotiated all the minutiæ magnificently, frequently made suggestions which made negotiations easier and more cost effective and his communication was always immediate and exemplary. I cannot recommend him any more highly, a consummate professional. Merci Monsieur!


Guillaume has been fantastic to deal with.

Excellent communication and helped me picked my dream apartment. He was always very quick to respond to my text messages and was available whenever I called him and needed to ask him questions. He provided me with all the information I needed to make my decision. He definitely set my mind at ease as well with my decision because he showed me all the other options that were great places in Detroit before I made my decision. I would recommend him to anybody, he definitely knows a lot about the area and definitely had a large array of options for me to review.


Guillaume is the hard working real estate agent that you have been searching for to help you find that next home.

He is very responsive and listens to meet your needs. After first talking with Guillaume he had 5 properties that I wanted to see. He was able to meet my busy schedule and got me into my next home within two weeks. Great Agent!

I've had a great experience with Guillaume so far.

He's very fast to respond to messages and has given me some good insight into the R.E. market that I never considered prior. He seems like a hard working, dedicated, and dynamic agent. Also very funny and entertaining to work with. Would highly recommend!

All I can say is WOW!

Absolutely consummate, attentive and committed agent. Making our purchase from the Antipodes, even with great time differences, remote transfer of all documents, and personal handling of visual and infrastructure inspections, Guillaume never missed a beat. I will ALWAYS recommend Guillaume to anyone looking to buy or sell property in the Detroit area. Guillaume made our dream purchase possible.


My husband and I worked with Guillaume and he was incredible.

He was very responsive if we had any questions, and he always kept us updated. I would recommend him to anyone.

Guillaume Derouet has intimate knowledge of the local market, we especially appreciated his ability to understand our needs and translate that to finding properties that matched our needs.

The advice and recommendations were also spot on and put us in a better position to negotiate.

Guillaume has always been of a great help for our divers House Hunting in Ann Arbor and Michigan.

He is very nice, easy to deal and all on the top of any request. Of course, the fact that he speak French helped us a lot - When I first came to USA from France, I was lost and he was so kind taking time to explain over and over again! I can not find a stronger word to say how satisfy of him I have been. I highly recommend him.

I met Guillaume while looking for an apartment to rent.

He narrowed down the list of apartments to fit my criteria and preferences and showed me a number of great places including one in a building I loved. I shifted to looking for a place to buy in that building. Guillaume was on top of apartments going on sale in and around that building, and once we found the perfect place, he assisted with the entire purchasing process.

Guillaume was the constant professional.

.Being disabled I had special requests, He listened and met my needs... He was always on time and answered all messages in an acceptable time frame..I have already told potential clients about him....


We had a fantastic experience with Guillaume during the initial buying process.

Once we negotiated the deal Guillaume was absolutely amazing to work with up to and throughout the closing process. Thanks for everything you did for us in finding our new Forever Home.


Guillaume went above and beyond for what I expected out of a realtor.

I reached out to him on a Sunday afternoon and he responded promptly. I flew out to Detorit that same week and only had two days to look for a place. Guillaume not only was able to make time for me on such a short notice, but he arranged around 15-20 properties for me to see in that short time span. He found places that fit my style and gave me a good variety of places to look at within my price range. Best of all, I never felt pressured and felt as of a good friend of mine was showing me my future home. His work ensured I got the place I wanted at a price that fit our budget. I would highly recommend anyone looking for their perfect place to work with Guillaume.
