17850 Santa Rosa Ave, Guerneville, CA — Value-Add River Community

A rare value-add opportunity in the heart of Guerneville, one of Sonoma County’s most desirable vacation and lifestyle-driven submarkets. Located near the Russian River and surrounded by strong demand for both short-term and long-term housing, this property offers investors a compelling opportunity to capitalize on renovation upside, Airbnb potential, and long-term appreciation in a highly supply-constrained market.

With approximately 1,850 sq ft across multiple levels after reconfiguration, the property offers strong potential for a value-add fix-and-flip project, luxury vacation rental, or long-term investment hold. Opportunities with public sewer, public water, usable square footage, and redevelopment flexibility are increasingly difficult to find in Guerneville.

Key Investor Highlights

Ideal Airbnb / Vacation Rental Opportunity
Homes near the Russian River with functional square footage, public utilities, and strong accessibility are becoming increasingly difficult to source in Guerneville. The area continues to attract strong tourism demand from Bay Area travelers, wine-country visitors, and second-home buyers, making this a compelling short-term rental candidate.

Public Sewer & Public Water
A significant advantage for the submarket. Many surrounding river properties still rely on older septic systems and private utilities, making public sewer and public water highly desirable for future ownership, renovations, and Airbnb operations.

Flexible Zoning with Additional Upside Potential
Property is zoned R1 B6 4 DU, suggesting potential flexibility for additional dwelling units or future redevelopment opportunities (buyer to verify with Sonoma County). This creates additional long-term upside beyond a standard single-family renovation.

Clear Value-Add Fix & Flip Potential
Property appears to require a full interior remodel, presenting investors with an opportunity to create substantial forced appreciation through:
• Layout optimization
• Interior modernization
• Cosmetic renovations
• Outdoor entertainment improvements
• Airbnb-oriented repositioning

Large Functional Square Footage
At approximately 1,850 sq ft after reconfiguration, the property offers a larger functional layout than many competing river properties in the area, creating stronger resale and rental appeal.

Strong Lifestyle & Emotional Buyer Demand
Guerneville remains one of Northern California’s most recognized river communities, attracting buyers seeking vacation homes, Airbnb investments, and lifestyle-driven properties near wineries, redwoods, hiking trails, restaurants, and river recreation.

Multiple Exit Strategies
• Value-add fix and flip
• Airbnb / short-term vacation rental
• Mid-term furnished rental
• Long-term appreciation hold
• BRRRR refinance strategy
• Potential future multi-unit redevelopment (buyer to verify)

Supply-Constrained Market
Properties offering public sewer, public water, usable square footage, redevelopment flexibility, and proximity to the Russian River are increasingly limited within Guerneville, supporting long-term value and strong buyer demand for renovated inventory.
