"What impressed us most about Jon was his integrity. He was completely honest about what would and wouldn’t work for our goals - even when it wasn’t what we expected to hear. He always put our best interests first, and that made us trust him completely. We went to Jon with a rough idea of adding an ADU, but no clear direction. His expertise turned that idea into a real, well-planned project. He walked us through zoning, design, costs, and ROI with total confidence. If you’re considering an ADU in Boise, Jon is the expert you want."
"Without Jon we would have never considered the lot we chose, he saw the potential in it and for that we are indebted. He was by our side every step of the way - from driving us to every neighborhood we were interested in, to the initial meeting with the builder, and over-seeing the entire process for us while we were out of state. He helped us navigate it all, staying in constant communication and always willing to take us on a walkthrough of the build."
"Jon did an outstanding job for us and was very patient with our needs. We look forward to working with him again in the future when we downsize into a new home. He is very responsive and knew how to get us in to see properties as soon as they came on the market. He also listened to what we were looking for and made great recommendations."
