John Duff Testimonials:

John was there every step of the way and helped us as first time home buyers to find a home we absolutely love! He explained everything in terms we could understand, and was extremely patient and attentive. He was a great negotiator too, and we will use him again. – Jim and LauraK. -Broomfield

We couldn’t have asked for a better Realtor than john. He sold our house quickly (under contract in 2 days), and had an awesome marketing plan that included a 1 year Buyers warranty that helped get our home sold because it was an older home. Then he helped us find a replacement home that is gorgeous and we closed the same day on both.John is the best Realtor we have ever worked with, and we have worked with many over the years! Diane and James D – Longmont

I was a little worried that I wouldn’t get what I needed out of my home, and be able to find another home that I would like, butJohn Duff sat down with me and explained what I could expect from my home and gave me a bunch of choices that I had a hard time narrowing to one. I sold and bought and love my new home. John was really a good, knowlegable, and great agent who does what he says he will Kendra H – Brighton
