Description
LETTER OF DETERMINATION WITH 3 RIGHTS | SELLER FINANCING | INCOME-PRODUCING TRIPLEX IN MARATHON
Building rights are the scarcest asset in the Florida Keys, and this property comes with a Letter of Determination confirming 3 rights. That makes it an opportunity to hold, improve, or reposition a triplex in the Middle Keys with the entitlements already documented.
Seller financing is available: $500,000 down over a 5-year term at a competitive rate, a real advantage in today's rate environment.
The Property:
Three fully renovated units, all currently leased:
Unit 1: 2BR/1BA, spacious layout, modern open-concept interior
Unit 2: 2BR/1BA, fully renovated
Unit 3: Efficiency with a well-equipped kitchenette, ideal for a single tenant or short-term renter
Tenants are on flexible month-to-month leases, which gives a buyer immediate cash flow and room to change course later. Ample on-site parking keeps the property easy to manage.
Location:
In the heart of Marathon, minutes from shops, restaurants, and everything the Middle Keys lifestyle offers.
Who It's For:
Investors building a rental portfolio, or an owner-occupant who wants to live in one unit and let the other two help cover the cost of ownership.
Schedule your private showing today. Properties with documented building rights and owner financing don't come along often in Marathon.
