Rare NextGen in-law living in Walnut! This Spanish-style home offers a flexible NextGen in-law suite – perfect for multi-generational living or guests – plus 4 bedrooms, 3.5 bathrooms, 2,473 sq ft, a 3-car garage and gated RV parking, all on an approx. 19,606 sq ft lot, one of the largest in this established Walnut Valley Unified School District neighborhood.

Completed in 2019, it lives like new construction: a private courtyard with an outdoor fireplace, approx. 11-ft ceilings, open living and dining areas, a kitchen with a large center island, a low-maintenance artificial turf front yard, and a backyard pergola patio. Built green and smart with whole-house spray foam insulation and an owned, fully paid-off solar system (ground-mounted, no lease and no monthly solar payments) – per the seller, AC is rarely needed in summer. No HOA, no Mello-Roos, and a low total tax rate of approx. 1.2%.

Bonus: plans for a proposed detached 1,200 sq ft ADU (2 bd / 3 ba plus a 218 sq ft covered patio) are in application with the City of Walnut, and the rear-yard site is already graded and leveled.
