BAM Team RE is pleased to present Willowest Marina, a rare, income-producing waterfront property located at 3215 W Willow Rd on Bethel Island in Contra Costa County, California. Situated on approximately 4 acres directly adjacent to Bethel Harbor, the offering combines 25 covered boat slips, a 3-bedroom residence, and a detached garage under a single ownership a configuration that seldom comes to market in the California Delta.The property has historically operated under absentee ownership with a stable, long-tenured slip tenant base many tenants have occupied their slips for more than 10 years with consistent on-time payment history. Each slip is individually metered for electricity, with tenants responsible for their own usage, minimizing owner-side utility exposure. At the current asking price, the in-place income reflects an estimated 7.4% cap rate inclusive of property taxes and insurance, offering a hands-on owner-operator or marina investor a stabilized entry point with clear upside through active management, slip-rate increases to market, and ancillary income growth. INVESTMENT HIGHLIGHTS Rare waterfront find a large-boat, covered harbor-marina asset directly adjacent to Bethel Harbor; first-time offering. Estate sale priced well below appraised value, creating an unusual basis for a Delta waterfront asset of this scale. 25 covered slips across three size classes (40', 46', 50') accommodate a range of vessel sizes and tenant demand. Diversified in-place income: boat slips, 3-bedroom residence, and garage rental, each metered/managed separately. Long-tenured, stable tenant base many slip tenants of 10+ years with strong pay history reduces lease-up risk for a new owner.
