About this home
421 ISLEBAY DRIVE
Virtually Staged. 421 ISLEBAY DR, APOLLO BEACH, FL 33572 | 4 BEDROOMS + OFFICE + LOFT | 3.5 BATHROOMS | 3,341 SQ. FT. | 70 FT SALTWATER CANAL | PRIVATE DOCK | 10,000 LB BOAT LIFT | FIRST-FLOOR PRIMARY At 421 Islebay Drive, the Florida waterfront lifestyle begins in your own backyard. Set on 70 feet of saltwater canal frontage in MiraBay, this 4-bedroom, 3.5-bath home pairs 3,341 sq. ft. of living space with a private 29x4 dock with electric and a 10,000 lb boat lift. From time on the water to evenings on the covered lanai, the home is designed around enjoying life by the canal. Inside, the two-story layout gives everyone room to spread out while keeping the primary suite and dedicated office on the first floor. The main living area brings the kitchen and family room together in an open layout, complemented by a custom feature wall, electric fireplace and built-in shelving. Luxury vinyl flooring runs through the living areas and bedrooms. The kitchen is ready for everyday meals and entertaining with stone counters, a center island, breakfast bar, pantry, natural gas cooktop and 2025 KitchenAid appliances, including a built-in oven with air fryer. The first-floor primary bedroom has a walk-in closet and tray ceiling, while the en-suite bath has marble flooring, split vanities, stone counters, a garden tub and separate shower. Upstairs, three additional bedrooms and a 16x13 loft create flexible space beyond the main living areas. Two full baths serve the second floor, including a Jack-and-Jill bath. Updated bathrooms add marble flooring, new vanities and updated lighting. Important improvements add even more value: dual A/C systems replaced in 2024, water heater replaced in 2024, KitchenAid appliances added in 2025, and a new metal roof section completed in 2026 alongside the approximately 5-year-old shingle roof. French doors lead outside to a covered lanai, patio and fenced yard overlooking the canal. The concrete seawall, private dock and boat lift put the water at the center of daily life, whether you are heading out by boat or simply unwinding beside the canal. MiraBay extends the lifestyle beyond the property with a clubhouse, fitness center, community pool, tennis courts, parks, playground, golf-cart-approved streets and community boat ramp. The required HOA is $190 annually, and the home is connected to public water, public sewer and natural gas. ***** WHAT THE SELLER LOVES Having the boat right behind the house makes it easy to enjoy time on the water, while the fenced yard and covered lanai create a comfortable place to relax outdoors. The first-floor primary suite, dedicated office, upstairs loft, updated bathrooms and major 2024-2026 improvements make the home easy to enjoy day to day, with MiraBay's recreation and waterfront lifestyle just beyond the front door.

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
