Property Description
Value-add opportunity in the heart of the Russian River area. 17850 Santa Rosa Ave offers approximately 1,336 sq ft of existing living space and is ready for the right investor, contractor, or buyer looking to build equity through renovation. With the right vision and improvements, the property has the potential to be expanded and transformed into an approximately 1,850+ sq ft home with up to 5 bedrooms and 3.5 bathrooms (buyer to verify). Investor projections suggest a possible after-repair value exceeding $800,000, creating an exciting opportunity for a flip, vacation rental, or long-term hold. Located minutes from downtown Guerneville, the Russian River, wineries, and outdoor recreation. Surrounded by Sonoma County’s redwood beauty, this property offers the perfect canvas for a renovation project with strong upside potential. Bring your contractor and imagination—opportunities like this are increasingly rare in this desirable river community.

Recorded sales in this period (0)
No recorded sales in this range. Select All available for older records; missing records do not mean the home never sold.
ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
