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 is 42' x 140' and 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 20' x 20' garages/workshops with power offer abundant space for equipment or hay storage. Ride year-round in the large 80' x 120' covered arena with sand footing, lights, and breathtaking Mt. Hood and territorial views. A second outdoor grass arena is 90'x180'. Enjoy trails that wind through the property, down to the creek and around the perimeter. There is also a trail course. 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. Backs to BLM land and next to a vineyard. 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!
