About this home
You won't see it from the road. The drone almost missed it too — 48 Black Flats Road sits so far back under the trees it barely shows from above, until the trees open and nearly two acres appear, Cape Cod Bay flashing beyond the marsh toward Mayflower and Bay View. The world outside disappears somewhere back along that driveway, and it stays that way.The real reason to know this address has never been square footage. This corner of Dennis grew up around one family's businesses — Roses Italian restaurant, Thelma's gift shop, mini-golf, and a handful of little cottages for rent — and for generations, every summer here revolved around them. It was the kind of place where everybody knew your name, and you didn't have to be related to belong — you just became part of the summer family anyway. Most of those landmarks are gone now, but they're still very much alive in people's hearts. It's hard to find anyone who grew up around here who doesn't have a memory tied to this stretch of Dennis — a lot of us were chambermaids in those cottages at some point, or discovered years later that the house we live in now was once one of them. Some of us still have a small treasure from Thelma's, bought with our own money as kids, tucked away in a memory box somewhere. 48 Black Flats sat right in the middle of all of it, and owning nearly two acres here means carrying a piece of that Dennis folklore forward.The house itself: a solid 1972 Garrison Colonial, about 2,100 square feet, four bedrooms, good-sized rooms, a real fireplace, mudroom, laundry, and a traditional layout. The roof, windows, and systems are all original and all working — this house hasn't been renovated, but it has been cared for. Move in as-is, rent it out for strong summer income, or take a big, solid house on nearly two private acres and make it entirely your own.Nearly two acres across two parcels, a long private driveway that keeps you completely tucked away from the road, and a wide clearing around the house with room for a pool, gardens, or whatever you're picturing. The beach is about six-tenths of a mile away as the crow flies — a bit longer on foot following the drive out, an easy bike ride any summer morning.Town water, R-60 zoning, and part of the property sits in FEMA Flood Zone AE — buyers and buyer agents should do their own due diligence on insurance, septic, and zoning.The house needs some updating. The story behind it doesn't.
