Despite the original structure being built in 1978, the property has undergone extensive and recent renovations. The ADU was built 5 years ago, and the main house was 'recently remodeled' with significant upgrades (200-amp electrical panel, 6 kW solar system, 18 SEER HVAC) also completed 5 years ago. The images confirm modern, high-quality finishes in the main house kitchen (white shaker cabinets, quartz counters, stainless steel appliances, wood-look flooring) and bathrooms (modern vanities, fixtures, and flooring). All major systems are new or recently updated, permitted, and meet current quality standards, indicating virtually new components and no deferred maintenance.
Pros & Cons

Pros

Exceptional Income/Multigenerational Potential: This property is a true triplex, featuring a main house, a fully equipped ADU, and a JADU, offering significant rental income opportunities or ideal accommodations for large multigenerational families. Each unit boasts its own private outdoor space.
Extensive Modern Upgrades & Energy Efficiency: Recent remodels to the main house, a newly built ADU (5 years ago), a fully paid 6 kW solar system, high-efficiency HVAC systems (18 SEER for main/JADU, 20 SEER for ADU), and a 200-amp electrical panel ensure modern comfort, lower utility costs, and reduced maintenance.
Permitted & Inspected Improvements: All significant improvements, including the ADU, JADU, pool, solar, HVAC systems, and electrical panel, are fully permitted and have passed all city inspections, providing peace of mind and ensuring compliance.
Resort-Style Outdoor Living: The spacious backyard features a heated swimming pool, patio, kids’ playground, automatic landscape lighting and sprinklers, and a diverse orchard of numerous fruit trees, creating an ideal environment for relaxation and entertainment.
Enhanced Security & Views: Equipped with a Ring alarm and camera system for modern security, the property also benefits from desirable mountain views, adding to its aesthetic appeal and value.

Cons

MLS Listing Discrepancy: Living area discrepancy between mls listing and other public or private record. mls listing living area = 3011, other record living area = 1859. Bedroom count discrepancy between mls listing and other public or private record. mls listing bedroom count = 7, other record bedroom count = 4.
Age of Original Structure: While the main house is recently remodeled, the original structure was built in 1978, which may imply older foundational elements or infrastructure not covered by recent upgrades, potentially leading to future maintenance considerations.
Complex Management: Operating as a triplex, managing multiple tenants or family units across three distinct living spaces can be more complex than a single-family residence, requiring additional oversight for leases, maintenance, and shared utilities.
Potential for High Utility Costs: Despite the solar system and high-efficiency HVAC, a property with three units and a heated swimming pool can still incur substantial utility expenses, especially if the solar system does not fully offset the total energy consumption of all units and amenities.
