Single Family Home for sale in Soap Lake, WA

for $1,300,000 with 6 bedrooms and 4 full baths. This 4,371 square foot home was built in 1953 on a lot size of 3.96.

Set across beautifully cultivated grounds, The Soap Lake Rosarium Estate unfolds as an immersive property where architecture and landscape exist in quiet continuity. Meandering pathways, established trees, and layered gardens create a sense of cohesion, offering both intimacy and scale. At its center, a formal two-acre rose garden - home to more than 1,500 rose bushes - anchors the estate, balancing structure and romance with spaces for gathering and reflection. Verdant arborvitae, planted three-deep, encircle the four-acre property, creating both privacy and beauty. Two distinct residences are thoughtfully positioned across the grounds: one set within the rosarium, intimate and closely tied to the gardens, and the other on its own landscaped parcel, offering greater scale and separation. Together, they create a natural rhythm between living, hosting, and retreat. The property is both a personal sanctuary and a successful vacation rental, offering immediate income potential, with opportunity to evolve into a destination for private events, weddings, or wellness retreats - subject to buyer vision and local guidelines. Within close reach of Soap Lake, nearby wineries, and the seasonal energy of The Gorge Amphitheatre, the estate balances proximity and seclusion - offering a place to live, to host, and to return to, across seasons and over time. https://rosariumestate.com/
