Testimonials


Colby was fantastic to work with, he was always available when we had any questions and had tips and tricks for us throughout our purchase. He gave us advice and kept us up to date throughout the entire process. We would absolutely use him again if we ever decide to move, purchase a second home, or if anyone we knew was looking to sell or buy.

- Meagan Williams

As we were looking to move out of the Eugene area to someplace that fit our values and lifestyle better we dealt with a number of realtors until we met Colby Marshall. If I had to describe Colby in as few words as possible I would say honesty and integrity would be the first two words I used. He is very knowledgeable and not afraid to tell you if he doesn't know something. Colby went above and beyond what we expected in a realtor and I couldn't recommend him highly enough.

- Jesse Rodolf

Working with Colby at Blackburn was a great experience. I bought the house site unseen. Colby answered all my questions, he's just what you're looking for in a realtor, honest, friendly and knowledgeable.

- Dawn Lippert

My husband and I were essentially first time buyer and sellers. We had purchased our home through a friend and now we're faced with a huge move from Oregon to New Mexico. We read all the "Dummy" books so that we would know what to look for in a realtor. We picked Colby because of his past work ethics. We were faced with buying a home in New Mexico while still living in Oregon. Colby worked with the realtor we had picked in New Mexico and helped us understand the different rules and regulations. He also made a very stressful situation of selling a home while my husband was living and working in New Mexico. We had a unique older home and he and Blackburn Real Estate found us the right buyer. We would recommend him to anyone needing real estate services.

- Rhonda/John Petty

Our Agent Colby Marshall was great. He found exactly what we were looking for. We Bought it sight unseen except for our Daughter looking at it for us. Not only did he get all of the paper work done for us he has also helped with other things that we have needed to get done and pointed us in the right direction. I highly recommend Colby Marshall or any one in that office.

- Eagle Ridge Kennels

Colby was phenomenal through the process of purchasing our new home and business. He's professional, prompt, knowledgeable, straightforward, reassuring, personable, and FUN to work with. He's an asset to our community, and I'd steer anyone his way in a heartbeat.

- Roger & Shani Hodge

Colby went above and beyond to help us purchase our first house! He helped us with everything from knowing how to start the process of buying a house to showing us potential properties to becoming successful homeowners. Colby was knowledgable about the different types of home loans and what houses would best fit our family. He helped us navigate buying a house from half way across the country by setting up meetings at times that worked for us and showing us properties virtually. Colby was an amazing asset to have on our team as we worked through buying a house and we highly recommend him!

- Matt & Katie Hanneman

Very friendly, and knowledgeable about the area. Quick to respond to questions/requests. Worked well with our schedule coming in/out of town from out of the area to find a home. We were grateful for his service and in a tough market, he was able to help us find the home that fit us!Cody & Jamie Rusow

- Cody & Jamie Rusow

Colby helped us sell our horse property/home and helped us buy a hay farm we didn't think possible to get. He was so helpful, professional and easy to work with. We highly recommend him to anyone looking for a Realtor to help them sell or buy. He was also very patient with us through the process as our financing took us a bit of time to attain.

- Derek & Amanda Hammer

Colby was super helpful and knowledgeable. He was available and willing to answer all the phone calls and questions we had. He was patient with our search process to find our new home. Thank you Colby we love our place.

- Larry & Renne Griggs

Many qualities of personal relationships are lost in today's high-paced world of technology. I can honestly say that Colby Marshall holds his business relationships in the highest regard, honesty, integrity, and loyalty are a few words I would use to describe Colby. Not only is he extremely knowledgeable about ranch land, farming, buildings, livestock, and real estate in general, but he is also great with people, very well-spoken, and a superb listener. Colby has turned a great buying experience for us into a lifelong friendship.

- Bob & Lisa McLean

From the first time I spoke with Colby Marshall, I knew he had my right interest. Help me get my first house and sell that house later on. If you want someone to go over and beyond to make things happen, then he is your guy. Blackburn Real Estate is a great team to work with. Colby ended up being a good friend that I can trust and count on. Call anytime for advice.

- Frank Cole

Colby hit it out of the park. My wife and I worked with Colby to purchase a small piece of property adjoining our home. Financially, this was not a large deal but there were multiple layers of complexity involving multiple owners and issues with the existing deed. Despite the preceding, Colby worked his butt off and somehow, improbably, made it all come together. Can't ask for more than that and we would definitely work with Colby again. I highly recommend reaching out to Colby for any of your real estate needs.
