Property Description

**Spacious One-Floor Living with Character, Updates & Over 1,800 Square Feet!** Welcome to 3128 Diamond Avenue—a spacious and distinctive 3-bedroom, 1.5-bath ranch offering more than 1,800 square feet of comfortable one-floor living. One of the largest homes on the street and ideally situated at the end of a cul-de-sac, this well-maintained home combines the character and craftsmanship of an older home with many important modern updates. A handsome stone facade and covered front porch create an inviting first impression. Inside, you’ll find an open and easy-flowing floor plan connecting the kitchen, dining, and living areas—perfect for both everyday living and entertaining. Large windows fill the home with natural light, while beautiful original hardwood floors, coffered ceilings, and a wood-burning fireplace add warmth and architectural character rarely found in newer construction. The updated kitchen features granite countertops, a stylish backsplash, stainless steel appliances, and plenty of workspace, all opening naturally to the main living and dining areas. Fresh interior paint provides a clean, move-in-ready feel, while an updated roof and HVAC system offer added peace of mind. All three bedrooms, both bathrooms, and the main living spaces are conveniently located on one level—making this an excellent choice for buyers seeking comfortable, accessible one-floor living without sacrificing space. Outside, enjoy both covered front and rear decks, providing inviting spaces to relax, entertain, or enjoy the outdoors in any season. Conveniently located near shopping, dining, and major highways, this home stands apart with its generous size, desirable location, recent updates, and a spacious one-level layout that is increasingly difficult to find. **If you’ve been searching for a ranch home with lots of space, character, and the right combination of classic craftsmanship and modern updates, you won’t want to miss this turn-key home.**
