Yes, you read that right: a 2.75% assumable loan paired with three years of financials averaging $207K in annual income. Welcome to a Mission Beach tri-plex that does the math for you. Tucked just steps from both the bay and the ocean, this coastal investment delivers true SoCal lifestyle appeal. The front 2-bed/1-bath house offers a private deck, wood-burning fireplace, updated kitchen, in-unit laundry, and ample interior storage. Upstairs, two beautifully remodeled studios share a sunlit deck made for slow mornings and golden-hour evenings. An attached garage and a dedicated outdoor area for boards, bikes, and beach gear round out the package, giving guests (and owners) everything they need to live the Mission Beach lifestyle. All three units run as active short-term rentals with a proven 5.94% cap rate and consistent year-over-year performance. Whether you're an investor expanding a coastal portfolio or a buyer planning to live in one unit while the others cover the mortgage, the assumable financing alone makes this a rare opportunity. Three income-producing doors, one of San Diego's most in-demand STR markets, and a financing structure that simply doesn't exist in today's rate environment, this one will not last! All units will be available to see Monday, 6/15 at 4 PM. Multiple offers received - A few counteroffers sent but none accepted as of 6/13 you still have time to submit - Calling for all offers now!
