SUMMARY
Estimated Market Value
Condition Analysis
OVERALL CONDITION SCORE
Property is extensive renovation needed.
The property, built in 1973, is explicitly marketed as an 'AS-IS' sale requiring a 'full remodel.' The residence shows significant physical depreciation, with the listing description and images indicating that the kitchen, bathrooms, and major systems are likely original or severely outdated and in need of total replacement. The primary value of this offering is concentrated in the 6.4 acres of land and the existing water meters rather than the current condition of the dwelling.
PROSSTRENGTHS & OPPORTUNITIES
- High Available Lot Utilization
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 278784, living area = 1760.
- Development Potential
The offering includes three contiguous parcels totaling 6.4 acres with gentle, usable topography, providing a rare foundation for a private estate, equestrian compound, or multi-generational development.
- Valuable Utility Infrastructure
The property is equipped with multiple 1-inch water meters through the Rainbow Water District, which are highly valuable and increasingly difficult to obtain for new land projects.
CONSRISKS & DEFICIENCIES
- MLS Listing Discrepancy
Lot size discrepancy between mls listing and other public or private record. mls listing lot size in square feet =278784, other record lot size in square feet = 94089.
- Extensive Renovation Required
The existing 1,760 sq. ft. residence is sold in 'as-is' condition and requires a full remodel, which will necessitate a substantial secondary investment of time and capital.
- Dated Structure
Built in 1973, the home likely features original systems and materials that may require modern upgrades to electrical, plumbing, and insulation to meet current building standards.
About 3655 Lupine Lane
Multi-Parcel Fallbrook Estate Opportunity | 6.4± Acres + Expansion Potential A rare opportunity to acquire three contiguous parcels totaling approximately 6.4± acres in Fallbrook’s desirable rolling countryside, offering a unique combination of existing residential improvements, highly usable land, and multiple water meters—an exceptional foundation for a private estate, multi-generational compound, or strategic land investment. The offering includes a 3-bedroom, 2-bath residence with approximately 1,760 sq. ft., situated on a 2.16-acre parcel with an attached 2-car garage. The home is being sold AS-IS and requires a full remodel, presenting an ideal opportunity for investors, builders, or end users seeking to create a custom residence or long-term estate. Also included are two adjacent parcels totaling approximately 4.24 acres (APNs 107-210-60-00 & 107-210-61-00), privately positioned on Lupine Lane just off Wilt Road. These parcels feature gentle, usable topography and are equipped with two separate 1-inch water meters through Rainbow Water District, a highly valuable and increasingly rare asset. A recorded road easement provides access through the front parcel to the rear acreage. Optional Expansion Opportunity – Adjacent Parcel Available Separately For buyers seeking additional acreage, the neighboring 4.06-acre parcel (APN 107-210-63-00, “Lot 4”) is also available for purchase separately under MLS #NDP2510861. If acquired in combination, the total landholding would expand to approximately 10.5± acres, creating an exceptional opportunity for a larger estate, equestrian compound, or expanded development footprint. Availability and terms of the adjacent parcel are subject to separate sale. Location & Lifestyle Conveniently located approximately 15 minutes to downtown Fallbrook and less than 10 minutes to I-15 and Highway 76, the property is surrounded by scenic rolling hills, citrus and avocado groves, nearby wineries, golf courses, hiking and equestrian trails, and a vibrant community known for the annual Fallbrook Avocado Festival, seasonal parades, and weekly farmers markets. Opportunities to acquire 6.4± acres with multiple water meters, existing access, and expansion potential in this prime Fallbrook location are extremely rare. Buyers interested in bundled land opportunities or the adjacent parcel are encouraged to contact the listing agent for full details. *Photos with boundary lines are approximate.
