About this home

HOUSE HACK OPPORTUNITY in the heart of Affton! This rare 3-unit property offers incredible flexibility for both investors and owner-occupants. The rear carriage house (2 bed / 1.5 bath) is now vacant—perfect for an owner to move in immediately while offsetting the mortgage with income from the front duplex. Situated on one lot, the property includes a front duplex with two units (2 bed / 1 bath and 1 bed / 1 bath) plus a separate 2-story carriage house featuring its own private yard and parking. The duplex offers a full basement with individual laundry hookups, along with a covered front porch and rear deck for added tenant appeal. Currently generating $2,026/month from the occupied duplex units, with additional income potential from the now-vacant carriage house. Opportunity to significantly increase rents to market rates or owner-occupy for added flexibility. Major updates provide peace of mind, including new roof, siding, gutters, soffits, and fascia (2022), updated bathrooms...
