Absolutely stunning 21.42-acre horse property on sought-after Mason Hill Rd! Originally developed as a premier equestrian facility in 2019, this unique property is fully fenced and cross-fenced, with 200 feet of serene Jackson Creek frontage. The impressive 19-stall barn features oversized 12x14 fully matted stalls — 10 with attached runs — plus a wash rack, paddocks, and lush pastures for turnouts. A Tuff Shed serves as the tack room, and two utility garages/workshops with power offer abundant space for equipment or hay storage. Ride year-round in the large covered arena with sand footing, lights, and breathtaking Mt. Hood and territorial views. Enjoy trails that wind through the property, down to the creek and around the perimeter. A finalized building permit for a future residence is in place with Washington County, and a new septic system and perc test have been approved. A new well was installed in 2023. This truly special property combines top-notch equestrian amenities with the rare opportunity to build your dream home in an idyllic, private setting — ready to make your equestrian vision a reality!
