About This Home

11285 3rd Avenue Gulf

This is a great opportunity to purchase a Concrete Block Deep Water Access Canal Front Home in the Heart of Marathon on the Gulf side of US 1 below $1M. With about a 4 foot control depth and an existing concrete seawall in place and about 77 feet of frontage, this property can easily accommodate the larger center consoles. Open Water Access in just a few minutes to the Gulf and about 10 minutes to the Atlantic Ocean. The home features 3 Beds, 2 baths, with 1,242 sqft on a large 8,485 offering sqft lot with a Concrete Driveway, Room to Park a RV, Boat Trailer, and room for a pool. The rear Covered Screen Lanai overlooks the canal, and the Covered Carport has built in Storage closets. The home features a Metal Roof and inside it does offer original 1960's charm with a ton of potential as right now it has original Kitchen Cabinets, Terrazzo Floors, Mini Splits in almost all the rooms for efficient air conditioning and original windows. Both baths have original tile showers with 1 being a Full Shower and the other featured a tub/shower combo. With the house right next door just selling at 11295 3rd Avenue Gulf for $1.45M, you have a unique opportunity to acquire, make smart renovations and be sitting on strong positive equity if done right. Due to the lot size, you can even choose to knock down the existing house and build a Brand-New Modern home to your exact specs and take advantage of the deep-water canal. We currently have plans for homes ranging from 1750 sqft to just below 4000 from the well-respected local builders, Design Center. We also have local lenders in place to offer construction financing up to 80%. So much potential and routes you can with this one.
