Investment Highlights

This is not a CAP Rate Investment deal. This is an opportunity to buy and develop the property, increase occupancy, and maximize its potential. Major Upside Potential in Rent and Redevelopment.

Financial highlights package for the sale of Grassy Key Marina, Marathon FL provided upon an executed NDA:

1. Executive Summary:

• 22,000 SF of buildings in the Marina which is located on 2.7 acres in the heart of the keys.

• This is not a cap rate investment deal but a value-add proposition or redevelopment. Carrying on the vision of the current owners or putting a different model in place.

• Important Financial metrics, such as revenue growth, profitability, and occupancy rates.

2. Financial Overview:

• Historical Financial Performance: Profit and Loss Financial statements for the past 4 years, showing revenue, expenses, and net income.

• Revenue Streams: Dockwa break down revenue by different sources (e.g., slip rentals, dry rack, outdoor storage, indoor dry stack, ramp fees). Growth has taken place in each of the last 4 years.

3. Market Position and Potential:

• Competitive Positioning: Grassy Key Marina has underperformed as a marina for years but this ownership has targeted low rents, 1st floor storage (no forklift), and appearance as areas of improvement. Less trailer storage, more boat racks, fork lift purchase, higher rents, better services, more professional appearance, and an online presence to improve occupancy.

• Growth Opportunities: Occupancy can be improved from 40% to 90% over time. The marina needs to expand services, like detailing, mechanics, and daily storage while increasing occupancy, and raising rates.

4. Operational Efficiency:

• Cost Management: Grassy Key Marina ownership has spent lots of money on improving the property from a new roof on the grocery store and re-building the upper bunks of rack storage that were taken out, while managing operational costs effectively.

• Operational Metrics: Occupancy rates have remained stable with an increase on last year, with the average price per customer rising. With average revenue per slip rising we lost some cheaper customers but replaced them with better quality boats and customers paying higher rates.

5. Investment Rationale:

• Unique Selling Points: Grassy Key Marina is the only full-service marina on Grassy Key. The property comes with 22,000 SF of buildings, including stores, storage barn, maintenance areas, 4 apartments and offices, 33 wet slips although larger boats moored in the basin allows for 23 boats comfortably. The customer base is loyal and the facilities are good. The facilities could be improved and expanded and a premium charged.

• Future Projections: We have offered a forecast of financial performance based on current trends or planned improvements. This will increase the occupancy and value of the property over the next few years. This is the vision and value add that the property offers.

6. Asset Valuation: Current Rent Rolls, Market Occupancy, and Rent information, brought us to assumptions on the projected values

2024 – approx $10,900,000 plus lots of potential (Currently 45% occupied)

2025 - approx $15,500,000, plus potential when occupancy gets to market rates

2026 - approx $20,000,000 with lots of potential if extra racks built once at market occupancy

7. Sale Proposition:

• Asking Price: The asking price reduced from $12,900,000 to $10,900,000

• Terms of Sale: Closing not contingent on any site plan approvals or any development plans. A Due Diligence Period will be given where a vault with all information, surveys, zoning,

8. Supporting Documents:
