Dennis O'Riley's Reviews & Ratings

Tell us about your experience with Dennis O'Riley

    • "Dennis was the perfect realtor for our first home purchase. Dennis was available any time we needed him. We made our initial contact on a Sunday evening, expecting we'd hear back in a few days. Dennis responded within the hour. He was always available when we had questions, and as first-time home buyers, we had a lot! Dennis took our wish list and made it real. He helped us decide on the best home for our budget and preferred neighborhood. He helped walk us through the financing process as well. We 100% trusted Dennis with every aspect of this home purchase. We were so impressed when Dennis was honest with us about whether or not he would buy one of our home choices himself. That shows that he's not just about making a sale, but about helping us find the perfect home. When the time comes to sell our house (which will be a while, since he found our perfect one!), we will definitely contact him again. Dennis is a fantastic realtor, and we are very thankful."

    • I found Dennis to be the consummate professional. His energy level is contagious. Whatever services I needed from staging, drone video, open house, etc., Dennis had the right resources available at the right time. Dennis truly understands how to market your property to get the most exposure possible. In purchasing a property, Dennis was an advocate for me to make sure I got the best price, and made sure anything that was owed to me was not missed, no matter how large or small that amount proved to be. Bottom line is that Dennis really cares for his clients.

    • If there is a walking definition of a real estate agent who listens to what your needs are, accommodates those needs in a professional manner, and takes the extra time to communicate every step of the way that would be Dennis. My experience with Dennis was outstanding on every level. If you are looking for something other than the "run of the mill' real estate agent who seems too busy to customize his time to your needs, look no further, contact Dennis.

    • I just want to relay to anyone interested in selling a home why I think you will make a mistake if you do not consider Dennis ORiley to represent you. First, a little background on Dennis: I had the privilege of working with him many years ago in the corporate world. Dennis was also successful in that environment and for many of the same reasons: Commitment to his clients, integrity, willingness to do the hard work and consistent follow through.We recently listed our home with Dennis and in typical fashion his planning for the sale was excellent, his execution on the marketing plan thorough and his support through the entire effort was outstanding. Of course, it didnt require a very long time because we went from listing to a closed deal in less than 30 days. Along that short path Dennis helped with everything from negotiating the final agreement to helping line up the right contractors on several repairs from the inspection follow-ups. Here is the net on this, Dennis will provide a very focused and personalized level of service and he will do what it takes to get your house sold.

    • I used Dennis' services to help me with the sales of my town home, and the purchase of my new home. The sale went extremely smoothly. Dennis hired at his own expenses a staging expert and photographer. Our listing looked great and the town home was gone in a matter of days. Dennis was very reactive and available for the showings. He was able to guide us thru the whole buying process. Also, He did not hesitate to recommend that we avoid buying some specific properties, if he thought they would not be a fit for us. His advice has been sound and honest. I will definitely use Dennis again if I have to move and buy/sell another place.

    • "Polite, punctual, expert and knowledgeable, he met all the criteria for a good professional agent. He was up-to-date and represented very useful information I needed to know for buying a house. He never tried to persuade me to buy something I didnt like. He always tried to describe honestly what problems the houses had. I was so glad to have him as my agent".
