A unique opportunity to acquire multiple 2-4 acre homesites for spec home development within Thomas Mountain Ranch, a gated custom home community in the scenic Anza Valley. Set at the base of Thomas Mountain, this offering provides additional flexibility for buyers seeking a larger private setting, a multigenerational living arrangement, or the opportunity to plan separate custom residences on individual parcels, subject to applicable approvals. The surrounding landscape features native vegetation, mountain views, and over 150 acres of preserved open space that contribute to the community's quiet rural character. Paved roads, electrical infrastructure, and high speed fiber optic connectivity provide a valuable foundation for future residential plans. Thomas Mountain Ranch also offers access to walking and equestrian trails, recreational amenities, a community vineyard, and gathering spaces that complement the area's outdoor lifestyle. Located within reach of Palm Desert, Temecula, and Idyllwild, the community offers a compelling balance of seclusion and regional accessibility. Whether held as individual properties or considered as part of a coordinated development plan, this collection of homesites presents an opportunity to secure additional land within an established gated setting. Previously approved plans are available with purchase.
