    Overview

    Historic Mixed-Use Income Property

    Located in the heart of downtown Charleston, 21 Broad Street presents a rare opportunity to own a fully renovated, income-generating historic property. Originally constructed in 1802 and completely updated in 2018, with additional improvements in 2023, this 4,254 square foot mixed-use building spans four floors, providing both commercial and residential income streams. The first floor features a professional office suite with a shared conference room and four private offices, suitable for business tenants or an owner seeking a Broad Street address. The second floor is a 2-bedroom residence operating as a successful short-term rental with a grandfathered B&B license. The top two floors house a spacious 3-bedroom, 2.5-bath apartment with updated kitchen and baths, ideal for long-term rental income or owner occupancy. The property is currently fully leased with tenants in place, grossing $242,000 annually. Additional features include two off-street parking spaces, updated systems and finishes throughout, and a location within walking distance to the Battery, White Point Gardens, restaurants, coffee shops, and galleries. The property sits on a lot of 0.07 acres. Whether maintained as a turn-key investment, converted to a live-work arrangement, or adapted for full owner occupancy, 21 Broad Street blends Charleston's historic charm with modern function and proven rental income.

    Realmo Value Estimation

    Realmo estimates a property’s market value using a proprietary methodology that incorporates public data and user-submitted information. This cumulative value is generated by integrating a variety of conventional and innovative methods. 

    Disclaimer

    These figures are not official appraisals and should not be used as a substitute for a valuation performed by a licensed appraiser.

    Actual market value may differ due to factors not captured in the data. Estimates are offered for informational purposes only, and users should conduct independent research before making financial or investment decisions.

    By using this feature, you acknowledge that Realmo is not responsible for actions taken based on these estimates.

    AI approach

    Realmo AI Method estimates property value using machine learning models trained on millions of comparable listings, transactions, and market signals. It analyzes property features, location intelligence data, and current market dynamics to predict the most probable market value in real time.

    Cap approach

    Capitalization Method calculates value based on estimated net operating income (NOI) and applying a market-based capitalization rate (cap rate), we estimate what a typical investor might be willing to pay for it.

    Comparable approach

    Comparable estimate is based on recent sales of similar nearby properties, adjusted for factors like size, condition, and location.

    Relative

    Relative property class coefficient uses factors that account for typical price differences between various asset types (e.g., retail vs. industrial) to provide a more accurate market-aligned estimate.

    Geo

    Comparable Sales Method, enhanced by Geo coefficients — location-based adjustment factors that reflect differences in price levels across neighborhoods, cities, or regions ensuring a more accurate, market-sensitive valuation.

    Alternative use

    Estimate considers the property’s potential value if used for a different purpose-based on zoning, demand, and market feasibility.
