Condition Analysis
See Full ReportOVERALL CONDITION SCORE
Good
TeardownExcellent
Property is move-in ready.
Built in 1993, this property has been well-maintained and features significant updates that appear to be within the 5-15 year range. The kitchen is modernized with stainless steel appliances and stone countertops, and the bathrooms show contemporary finishes. The home is move-in ready with high-end systems like a professional Dolby Atmos setup, though the overall age of the structure and style of renovations place it in the 'Good' category rather than 'Excellent'.
PROSSTRENGTHS & OPPORTUNITIES
- Premium Waterfront Amenities
The property features a private dock equipped with dual HydroHoists and direct access to 1,100 miles of Delta waterways, offering an elite setup for boating enthusiasts.
- Superior Vehicle Storage
An oversized 4-car shop-style garage with 10'6" ceilings and a 10' RV door, plus a large 'U'-shaped driveway, provides exceptional space for boats, trailers, and luxury vehicles.
- Expansive Custom Layout
With nearly 4,700 sq ft of living space, the home includes a massive 725 sq ft primary suite and high-end features like a professional-grade 11.1 channel Dolby Atmos surround sound system.
CONSRISKS & DEFICIENCIES
- MLS Listing Discrepancy
Bedroom count discrepancy between mls listing and other public or private record. mls listing bedroom count = 4, other record bedroom count = 3.
- Extended Market Time
The property has been active for 139 days, significantly exceeding the typical market duration, which may lead to buyer skepticism regarding its liquidity or condition.
- Price Volatility
Three consecutive price reductions from the original $1.65M listing price suggest a struggle to align with current market value, potentially impacting buyer confidence.
