    Description

    This exceptional 2,280 square foot retail space is located in a beautifully renovated (2011) 4,150 square foot building in the heart of downtown Danielson, CT. Built in 1900, this iconic structure boasts unique architectural details, including beautiful woodwork and a charming design, making it one of Connecticut's most recognizable commercial properties. The space features a large reception area, front, side, and rear entrances, a private loft office, a cleverly concealed maintenance closet, and a full bathroom with a shower. Benefit from easy access to ample free public parking (70+ spaces) and extremely high year-round vehicle and foot traffic. Currently, there are tenants in place at below-market rents with upcoming lease renewals, offering an owner-occupant the potential for significant rental income to offset expenses. The central business district (CBD) zoning allows for a variety of uses, including but not limited to a dispensary, liquor store, restaurant, coffee shop, or specialty store. The entire building is also available for purchase. This is a truly unique opportunity to own or lease a piece of Connecticut history in a thriving downtown location.

    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.
