    Overview

    Gulf Front Estate in Marathon

    Located in the heart of Marathon, Casa Manana Shores is a secured gulf front estate offering 3.86 acres of land. The property is surrounded by an eight-foot concrete wall with three gated entrances. It features approximately 540 linear feet of highway frontage and 695 linear feet of water frontage, along with 218 feet of concrete dockage, including a protected boat slip. There is also room for a helicopter landing pad. Zoned mixed-use commercial, this property comes with one commercial transferable building right. Currently a private residence with a separate garage and workshop, the 10,852 square foot mansion is of solid concrete construction with concrete pilings and copper pipes. It has ten bedrooms, six and a half bathrooms, a sauna, game room and great room. Repairs are needed, and the interior needs substantial updating. An attached partially screened enclosure holds a 25 x 50 ft swimming pool that is 12 ft deep. The garage/workshop is a separate structure with two rooms with mini split air conditioning. The existing structures could be demolished, leaving a 3.86 acre blank canvas in the center of town. Its versatile designation offers multiple possibilities for residential and/or commercial use. Over the years it has previously housed a motel with a marina, a 19-unit trailer park, and a restaurant. This property lends itself to a variety of development or rehabilitation possibilities.

    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.
