    What's special

    Enclosed front porchOversized yardDetached garage
    An extra-deep lot in downtown San Mateo with two units and room to grow. Built in 1907, this single-family home retains its original character, including an enclosed front porch. It has been converted so that each unit has its own full kitchen and bath. The front unit offers 2 bedrooms and 1 bath, and the back unit offers 1 bedroom and 1 bath. New heating and air conditioning are already in place. The possibilities are wide open. Live in one unit and let the rent from the other help cover the mortgage. Use both for multigenerational living, with privacy and independence under one roof. Or add it to your portfolio as a two-unit investment. The property is delivered vacant, so you can set your own rents and move at your own pace. Out back, the oversized yard is a rare find in such a central location. Mature fig and lemon trees frame a generous space for gardening and entertaining, with the potential to expand the existing home or add another dwelling. A detached garage and long driveway offer off-street parking, along with flexibility for storage, a workshop, or a possible future ADU conversion. Walk to the shops and restaurants of downtown San Mateo, with Caltrain and Hwy 101 close by for an easy commute anywhere on the Peninsula.
