213 N Main Street Located in the heart of Saint Charles' Historic Main Street District, 213 N Main Street presents a rare opportunity to acquire a fully stabilized, income-producing mixed-use asset in one of Missouri's most vibrant and heavily visited commercial corridors. This circa-1890 brick building offers 4, 524 square feet of well-utilized space and generates a true net operating income of approximately $83, 000 annually, translating to an attractive 5.35% cap rate at the $1, 550, 000 asking price. The ground floor is home to Reset, an established clothing and shoe resale retailer that benefits from the district's steady, year-round foot traffic. Above the retail level, the upper units operate as income-producing apartment and Airbnb rentals, capitalizing on Saint Charles' thriving tourism economy and persistent demand for short-term accommodations near the riverfront. This blend of retail and residential income creates a diversified rent roll that insulates ownership from single-tenant risk and delivers dependable cash flow from day one. Unlike value-add offerings that require capital and lease-up time, 213 N Main is a turnkey investment: the work has been done, the income is in place, and a new owner simply steps into a performing asset in an irreplaceable location. Historic Main Street draws visitors year-round with its brick-paved streetscape, boutique shopping, dining, and signature festivals, including the nationally recognized Christmas Traditions celebration. The property sits steps from the Missouri Riverfront, Frontier Park, and the First Missouri State Capitol Historic Site, with a nearby traffic count of 77, 283 vehicles per day and a Walk Score of 79/100. Downtown Saint Charles continues to benefit from sustained public and private investment, and surrounding values have appreciated 10% over the past two years. For investors seeking stable, diversified income with long-term appreciation in a proven historic district where buildings rarely trade hands, 213 N Main Street is a compelling, low-friction addition to any portfolio.
