4 Green St

Incredible Opportunity with Tremendous Upside in Martinez! Bring your vision and unlock the potential of this 3-bedroom, 2-bathroom, approximately 1,200 sq. ft. fixer-upper in a desirable Martinez location! Sale includes two adjoining parcels with separate APNs: the existing residence at 4 Green Street (APN 372-114-002-2) and an adjacent approximately 1,800 sq. ft. vacant lot (APN 372-114-001-4). Whether you're an investor, contractor, or buyer looking to create your dream home, this unique offering presents exciting possibilities. Renovate the existing residence and potentially increase the living space by utilizing the underused basement-level area, or explore expansion opportunities onto the adjoining vacant parcel. Consider the possibility of constructing an ADU for rental income or multigenerational living, or transform the additional land into a beautiful, park-like outdoor retreat with gardens, entertaining areas, and added privacy. The existing home requires substantial repairs and updating, but the potential upside is compelling. A rare opportunity to acquire two adjoining parcels and create something special in an established Martinez neighborhood! Property is being sold as-is. Buyer to independently verify square footage, parcel boundaries, zoning, and all expansion or development possibilities with the appropriate authorities.
