The Story

Coastal income, built on a corner block.

Two blocks from Windansea, on a 9,227 square foot corner lot with dual street frontage. The kind of parcel they don't zone anymore.

The Rosemont Six is a stabilized coastal multifamily property in Windansea, La Jolla's Mediterranean village. Six rental units across two stories of block construction, anchored on a flat 95 by 100 foot corner lot with frontage on both Rosemont Street and Electric Avenue, plus alley access to four single-car garages.

Of the six units, four are currently vacant and renovation-ready. Two two-bedroom, two-bath floor plans at roughly 900 square feet, two two-bedroom, one-bath plans at 800 square feet, and two one-bedroom, one-bath plans at 600 square feet. The unit mix is built for the renter La Jolla actually has: a tenured tech and biotech professional who wants to walk to the bluff before work.

Long-term market rents pencil at $29,800 monthly. Short-term and Airbnb operations reach $50,000 monthly. The four ten-by-twenty-four garages can be converted to 240 square foot studios for an additional $127,000 of annual income at current market rents. The asset is offered at $5,250,000 against an estimated stabilized market value of $6,900,000.

Windansea, La Jolla

Where the village meets the bluff.

Windansea is the south-coast village of La Jolla, organized around the surf break at Neptune Place and the Mediterranean blocks behind it. Year-round mild weather, mid-fifties to mid-seventies. A walkable retail and restaurant strip on La Jolla Boulevard. The bluff is two minutes on foot.

The local economy is anchored by education, healthcare, biotechnology, research, and professional services. UC San Diego, Salk, Scripps, and the Torrey Pines biotech corridor sit minutes north. The renter base for properties like the Rosemont Six is professional, tenured, and price-insensitive within reason.
