Condition Analysis

OVERALL CONDITION SCORE

PROSSTRENGTHS & OPPORTUNITIES

  • Great Schools

    Elementary School: Warner Avenue Elementary School (9/10).

  • Modern New Construction

    Built in 2025, this 5,400 sq ft masterpiece features cutting-edge architectural design, high-end finishes, and the rare luxury of elevator access to all three levels.

  • Prime Sherman Oaks Location

    The property boasts exceptional walkability to Ventura Boulevard, placing the city’s finest restaurants, cafes, and boutique shopping just moments away.

CONSRISKS & DEFICIENCIES

  • Limited Yard Space

    With a massive 5,400 sq ft footprint on a roughly 7,000 sq ft lot, the building-to-land ratio leaves a relatively compact outdoor area for a home of this scale.

  • Market Pricing Adjustment

    A recent $200,000 price reduction shortly after listing suggests the initial valuation may have been aggressive relative to current buyer demand.

  • Inconsistent School Ratings

    While the area is served by some high-performing schools, several nearby middle and high schools carry lower ratings, which may be a concern for education-focused families.
