In the prestigious enclave of Riomar Bay, this 0.55-acre property with 135 feet of river frontage is ideally positioned to capture the prevailing southeastern breeze. Previously the guest house for a larger estate, the 3,806 square foot building could easily be adapted for full time residency or start over and build your dream home. Combine this with the adjacent parcel (510 River Drive) for a legacy property without equal (a total of 594 feet of river frontage and 2.18 acres). The possibilities are endless. Golf cart to town, restaurants, the beach, farmer's market and Quail Valley River Club.
