NOTES FROM OUR CLIENTS

"Matt will go above and beyond to assist you in the sale/purchase of your property. He accomplished both of these for me within a minimal amount of time. He is a very caring individual, who continues to keep in contact with clients even after transactions are completed. Matt is a rarity in modern  business dealings; integrity and honesty are at the top of the way he and his team do real estate business. He is a hard worker, as is his entire team. Besides that, he is a genuine nice person!" - Nan (buyer & seller)

Nick was a phenomenal real estate agent for our first-time buying a home. He anticipated questions we would have before we even knew we had them! He made us feel very comfortable in what can sometimes be a very stressful situation. After only one time out viewing homes, Nick keyed on exactly what we were looking for, and he helped make our dream a reality. - Noah & Delaney, buyers

"Matt and his team were there with me every step of the way I really enjoyed the expertise and knowledge. Matt was very honest and helpful and letting us know what needed to be done to the home to get the best result as possible. He listed the home and it sold in 4 days, I couldn't have asked for  a better result." - Jim H, seller

"Sold my home after I'd already moved to East coast. Great neighborhood sense and interactive style. Took care of getting all house hold goods moved and all ends tied up. Effortless for me. A great person besides." —R. Simon, seller

"Matt (and his whole team) was excellent to work with, and very accommodating to my particular circumstances. They made sure to keep in contact with me and update me every step of the way; I felt incredibly comfortable having them handle my house sale." - Ashley, seller

"Katie is a rare find, because she will stay with you from the very first step all the way to the end. She keeps her finger on the pulse and does not miss a beat. She is your biggest  support, knows the business, and is an excellent coach during the entire process! I cannot recommend her enough!" — I. Schwartzman, buyer & seller

"There are no words for how amazing Sue and her team are. Within 24 hours of us starting to look for our first home, Sue had managed to help us to get our first offer accepted, after a bit of negotiation. She knew exactly what levers to pull in order to get our offer accepted though there were a number on the table." - Kim K, buyer

"I loved working with Katie and hope to work with her again. She was knowledgeable, very responsive, and really on the ball throughout our search for and purchase of a new lot. I can't recommend her enough." — K. & P. Meyer, buyer

"Working with Sue Sullivan to find and purchase our new home not only exceeded our expectations of what a realtor should do, but opened our eyes to all the things a dedicated, knowledgeable, and hard-working agent and team could do. Sue took the time to understand what we wanted, and helped us  expand our search in ways we hadn’t considered, based on her familiarity with the areas and neighborhoods, as well as a thorough understanding of the market trends. In the rare instance she was unavailable, Matt and Nick filled in seamlessly, and Sara was efficient and professional behind the scenes." - Buyer in Sherwood

"Sue was recommended to me by a close friend who has been one of Portland's top mortgage brokers for decades. I asked him who he would trust if he was buying a home for HIS family. He immediately referred me to Sue Sullivan, and I'm SO glad he did! Sue is the consummate pro, and a genuine  pleasure to work with. She and her team consistently gave great advice, and helped me land a great house in a great neighborhood They were always available when I needed them, and had terrific insight of the local market. I can't recommend Sue highly enough!" - Buyer in Portland

"Katie made our house sale so easy. From the very beginning she helped to develop a plan and then she helped us to execute it with precision. When any unexpected moments happened, she helped us breeze through it. That was the easiest house sale we have ever done!" — J. Horacek, seller

"Just completed my second real estate transaction with the Mahaffy group and wanted to especially thank Nicholas for all of his effort and the expertise he brought to the process. I have previously worked with Matt and Sue and their depth and experience always shines through. Nick's enthusiasm, level of skill and knowledge reflect competencies well beyond his age and experience -- I've worked with a number of agents in both Oregon and California and would place Nick in the top 5% of all professionals retained in the last decade. Kudos to Nicholas!" - Peter D, buyer & seller

"We wanted to sell our house quickly and Katie was able to help us out with that. She gave us great ideas about where to spend money to get it ready to sell and we were able to get the house ready in a few weeks. She had it on the market and an offer came in the first day. She is honest, fair and really went all out for us. She is very personable and funny so it felt like we had our new best friend helping us out." — K. and J. Brown, sellers

"Katie was on it. We bought a condo in PDX last summer and it was a seller's market. Very tight and very tough. Katie was knowledgeable, helpful and a pleasure to work with. Not only would I recommend her...I actually just did!" — R. Hagen, buyer

"Nick Swann is professional, attentive, patient, and detailed. He always communicated with us even when he was still waiting for updates, just to keep us in the loop which we very much appreciated. He was transparent and honest about the houses we viewed and the offers we made... I would highly recommend Nick and the Mahaffy Group!" - Chris & Frances, buyer

"Katie was great to work with. She was understanding, and patient with us. We turned down a lot of houses, and she just kept bringing us more. Eventually we were able to fine the perfect investment properties. Wouldn't do it again without her." — S. Eddy, buyer

"I have been fortunate to work with Katie for 2 home sales and one purchase. I will work with her again if/when it comes time for me to sell/aquire another home. Katie is super responsive. She is a great communicator and problem solver. I trust her personal knowledge and the expanded network she uses to support her in being an awesome realtor." —C. Driver, seller & buyer

"When you purchase a house, that's a pretty major purchase. You don't want someone who doesn't know their stuff or isn't very friendly. We've both bought and sold so many homes over the years, and this was probably the easiest, smoothest experience we could have had. We're actually selling for more than we thought it was worth. Add to that, you've got the warmth of Joe's southern charm!" - Kelly & Bruce, seller

This was a new process for us, so we had lots of questions and lots of 'talk us off the ledge' moments, and Joe was always available. He was almost at 'beck-and-call' throughout the whole process. We feel he went above and beyond, and he was really just a friend throughout it all." - Heather & Josh from Scappoose

"Katie helped us navigate what was an extremely tight market. Lets put it this way, we had a LOT of needs and Katie didn't seem to waiver in her goal to get us in a happy house. Where she really shined though, was in the mortgage process and dealing with a very difficult lender. During this arduous, inefficient process, I was out of the country a good deal of the time and Katie held everything together." —J. Ichter, buyer
