Sean’s Client Testimonials



Jeff Glover and Associates, Realtors were an awesome company to work with!! My sellers agent was Sean Ninness. When he first came to my home, from the marketing strategy, I knew they were the company my wife and I wanted to go with. He was extremely responsive through phone, email and text. He was very knowledgeable and answered all of our questions. He knew the market conditions very well also. The pricing strategy was awesome. he said they would price it right in the middle. Sean told us that we would get multiple offers on the home and it would go quick and it did. He put our home on the market on a Thursday evening and by that Monday we had 8 offers. With his great negotiation skills, sean was able to drive up the price of our home, where we ended up getting $8K more in our sale price!! And when we got the offers, sean went through each one in detail and gave us a recommended offer that he thought was the best deal. and he was spot on!! the deal closed in less than 2 months. We were so pleased with jeff glover and our agent Sean Ninness, that we would recommend them to everyone. Once we begin looking for our house next year Sean at Jeff Glover and Associates will be our buyers agent as well. If you’re looking, look no further Jeff and his team are amazing to work with!


From Day 1 to the final closing day Sean Ninness was top notch!!! I couldn’t have asked for better service from a realtor. He did everything it took to assist me in every way possible. Thanks, Sean. Very much appreciated!!


We listed my Mother’s home in Detroit with another agent for six months. We had hardly any showings and no offers. When it came time to put the house back on the market, we interviewed several agents for the job and Sean was by far the most prepared and professional agent we met with. He knew exactly what to do to get the job done. After only a few days on the market, we had several offers. There were a few obstacles along the way, but Sean was always available to answer questions and make sure we knew exactly what was going on every step of the way. I would HIGHLY recommend Sean to anyone that wants a professional to get the job done. Thanks Sean!


Sean is the best realtor I’ve worked with, he did everything he promised. He came out to my house gave me an honest assessment and never pressured me to sell. When I did decide to list my property was on MLS the next day, and I had several full price offers within 3 days. Sean stayed in contact constantly all the way through closing and even followed up post close.


What can I say in the past few months things have really fallen into place. I can not thank Sean Ninness enough for the great work he has done. Both on the buying end and selling end of our houses. I’m a happy man tonight and I own a lot of it to him.


I was tasked with selling the family home for my parents who had relocated to Florida. I interviewed a few agents and Sean was the last agent I spoke with. Had I met him first I would have saved my self the aggravation of meeting with anyone else. His product knowledge and good vision for marketing our family home was terrific. Sean did a careful analysis of the comps when we went to list and recommended that we price it at $174,000. The house went on the market on Wednesday and by Friday it was under contract at a price that was about $5000 over the original price. Six weeks later we closed the deal. Sean was very responsive to my questions and concerns and because we in the family are all out of town, Sean helped us by stepping up to be at the house when we couldn’t to meet movers etc. I highly recommend Sean Ninness.


Sean was great. He knew the area very well and was very helpful throughout the whole process. Sean knew what and where to look when showing me houses and was very forthcoming if he saw any potential problems with the property. He was responsive to what I was looking for and only showed me properties that he knew I would be interested in. We encountered quite a few speed bumps along the way with certain properties and appraisals but Sean was always patient and knew when to fight for something and when to move on.
