Middle School: Pioneer Junior High School (9/10).
The 'Grey Haven' backyard is a standout feature, boasting a 13-foot swim spa, a high-end outdoor bar with Twin Eagles and Perlick appliances, and professional landscape lighting.
The solar system is leased rather than owned, which requires the buyer to assume an ongoing financial obligation and contract as part of the purchase.
Despite its custom charm, the 1989 interior features—such as full mirrored walls—may feel dated to contemporary buyers looking for a fully modernized aesthetic.
