You were recommended to me by my daughter-in-la, a realtor herself in Arizona. She had quizzed several Boulder County realtors and found your answers the best. You made sure, always, that I understood what was being done. Please use my name so I may provide the outstanding recommendation you have earned.

Hi All, if your looking to buy a home around Longmont, give Mary Powell Colwell with 8z real esate a call. I just copied my zillow review here but if you want to talk about our experience give me a call or shoot me message. She is one in a million We came to Mary with dreams of acreage and not a big budget. We thought we might be able to find a property within our budget with around 2-3 acres. Mary found us the most darling farm house on 10 acres!!! We were over the moon. We put in an offer on the home, went back and forth few times and we were under contract! In the contract Mary asked the seller to certify the septic tank. This was not on my radar, but when Mary suggested it seemed like a good idea and the sellers agreed. Low and behold the septic tank was bad. But Mary had us covered. Her wording in the contract made it so the seller had to replace the septic tank. There was no negotiation about if this would happen and who would pay. We were surprised, the sellers were surprised. Mary was the only one who was not surprised. She is a master. We also had to change the zoning on the home so the bank could lend on it. Mary worked as a team with the sellers to get it done. Long story short. Mary knew what we wanted in a home. She knew going into it that the nature of what we wanted to buy was going to create more work for her at a lower pay off. She found us the perfect place. She worked her butt off for us to get it on the best terms possible. She jumped through all the hoops the bank required and got us into our new home before I needed to have my family out of our rental. She did it all with a smile on her face, upbeat and singular sense of purpose. Thank you Mary. We love our home and will always be grateful to you for getting us here.
