Description

Two homes being sold together make this an excellent house hack + future development opportunity! Live in the brand-new ADU and let the main house help pay your mortgage. On roughly 7,800 sq ft in San Jose, this property has a newly built, detached 2BD/2BA ADU (749 sq ft), vacant and ready for you to move in. The renovated 1BD/1BA main house (744 sq ft, built in 1930) rents at $3,000/mo. Prefer to hold both as rentals? The ADU projects at around $3,500/mo, for about $6,500/mo combined. BONUS 2 additional homes in the pipeline: Plans for a two-story duplex, with two 3BD/3BA units of 1,188 sq ft each, are already in permit review with the city. The design work is done, so you pick up where it leaves off instead of starting from scratch. Live on-site while you build out to four units. Close to Downtown, major tech employers, San Jose State University and freeway access. Excellent opportunity for investors, developers, builders looking for the next project.
