Welcome to 800 18th Avenue N, a historic 1925 Colonial pool home in Crescent Lake, one of Downtown St. Petersburg's most desirable, walkable, and tree-lined neighborhoods. Combining timeless architectural character with meaningful modern updates, guest accommodations, and an exceptional location, this rare property sits just steps from Crescent Lake Park and approximately a 15-minute walk to Downtown St. Pete and the St. Pete Pier. Recently refreshed and reintroduced to the market, the home was temporarily withdrawn to complete updates designed to enhance both presentation and livability. The main residence has been freshly painted inside, both detached guest apartments (ADUs) have been refreshed with new interior paint, nearly every ceiling fan in the main home has been replaced, and the kitchen now features all-new appliances including a refrigerator, dishwasher, stove, and microwave. Professionally staged and thoughtfully updated, whether you toured this home before or are seeing it for the first time, this is one you need to experience in person. Situated on a beautifully landscaped corner lot, the property features a 3-bedroom, 2-bath main residence plus two private one-bedroom guest apartments above and below the detached garage-an exceptionally rare Crescent Lake configuration ideal for multigenerational living, guests, home office space, Airbnb potential, or long-term rental income. Inside, authentic 1920s craftsmanship shines with a gracious living room featuring a decorative fireplace, built-in bookshelves, exposed beamed ceilings, and engineered hardwood flooring. A sun-filled downstairs sunroom creates a perfect reading or workspace retreat, while the dining room with built-in corner hutch was designed for gathering and entertaining. The kitchen offers granite countertops, breakfast bar seating, pantry storage, hardwood flooring, and brand-new stainless steel appliances. Upstairs, original pine hardwood floors extend through spacious bedrooms filled with natural light. The primary suite features a walk-in closet and adjoining sunroom that can serve as a home office, nursery, fitness room, or future third-bath conversion. Outside, enjoy your private backyard retreat featuring a heated saltwater pool with travertine decking, spacious entertaining areas, a covered pergola, and beautifully designed outdoor living spaces. The detached guest apartments overlook the pool area, creating a private and resort-inspired atmosphere. Major updates include a new roof (2024), HVAC systems replaced in 2021, and a new water heater (2025). Additional highlights include mature landscaping, lighted palms, travertine walkways, convenient access to I-275, airports, Gulf beaches, and importantly, no flood insurance requirement. Enjoy nearby restaurants, breweries, coffee shops, pickleball courts, scenic walking paths, baseball fields, and the rich history and charm that make Crescent Lake one of St. Petersburg's most beloved neighborhoods.
