Condition Analysis

OVERALL CONDITION SCORE

Fair
TeardownExcellent

Property is moderate renovation needed.

The property is exceptionally well-maintained by the original owner but remains largely in its original 1991 condition. While functional and clean, the kitchen and bathrooms feature dated oak cabinetry, white tile countertops, and period-specific brass fixtures that show their age. Recent updates to the HVAC (2020) and water heater (2025) provide mechanical reliability, but the overall interior aesthetic and original appliances require modernization to meet current 'Good' or 'Excellent' standards.

PROSSTRENGTHS & OPPORTUNITIES

  • Premier Location and Education

    Situated in the prestigious Timberline community, this property falls within the award-winning Walnut Valley Unified School District, a top-tier draw for families and a strong driver for long-term property value.

  • Exceptional Outdoor Living

    The large, professionally landscaped lot features a built-in BBQ, basketball court, and custom fire pit, all designed to maximize the breathtaking panoramic views of the mountains and canyons.

  • Functional Multi-Generational Layout

    The 3,028 sq. ft. floor plan includes a highly desirable downstairs bedroom and full bathroom, vaulted ceilings for ample natural light, and a spacious three-car garage, offering versatility for various living arrangements.

CONSRISKS & DEFICIENCIES

  • Dated Interior Aesthetics

    Being offered by the original owner for the first time since 1991, the home likely features period-specific finishes that may require significant cosmetic updates to appeal to modern luxury buyers.

  • Aging Infrastructure

    While the HVAC and water heater have seen recent improvements, other core systems and original 1991 components may be nearing the end of their functional lifespan, potentially leading to near-term maintenance costs.
