Listing description

Welcome to over 2700 sf of living space, where classic Conshohocken character meets beautifully updated, move-in-ready living on one of the borough’s most desirable and quiet residential streets. From the moment you arrive, the inviting covered front porch sets the tone for a home filled with warmth, charm and original architectural details. Step inside to find 9-foot ceilings, beautifully refinished original hardwood floors, original window and door trim, substantial baseboards and crown molding—details that give this home a character that is increasingly hard to find. The first floor offers a spacious, open flow designed for both everyday living and entertaining. The living room is anchored by an electric fireplace with a shiplap accent wall and floating mantel, while the formal dining room provides plenty of space for gathering. The bright white kitchen features stainless steel appliances, a center island and pantry. A conveniently located laundry area and powder room in the rear of the home complete the main level. Upstairs, the second floor offers two generously sized bedrooms, an additional smaller bedroom ideal for a home office, nursery or flex space, and a beautifully updated full hall bathroom. Continue to the third floor to discover a private primary suite retreat featuring a large closet and gorgeous ensuite bath with a dual-bowl vanity and seamless glass-enclosed tiled shower. The living space continues in the fully finished basement, perfect for a family room, home gym, playroom or media space, with additional storage and a convenient walkout to the backyard. Outdoor living is just as impressive. Enjoy morning coffee on the front porch, dinner on the rear deck, or summer evenings on the paver patio overlooking the fully fenced backyard, complete with a storage shed. And then there’s the location. West 3rd Avenue offers the neighborhood feel Conshohocken buyers love while keeping you just blocks from downtown restaurants, shops and nightlife. Walk to the train, easily access the Schuylkill River Trail, and enjoy convenient connections to major highways and everything the Main Line and Philadelphia area have to offer. Original character. Modern updates. Multiple outdoor living spaces. A fenced yard. And a walkable Conshohocken location. 138 W 3rd Avenue offers the best of borough living in a home that feels special from the moment you step onto the porch. Open Houses Saturday 8/22 & Sunday 8/23 - 1pm -3pm Both days.

Assessment note: this home is assessed at $113,930, well below the ~$171,350 its asking price implies at Montgomery County's common level ratio (29.8%). A sale near asking can invite a school-district assessment appeal that could raise the bill by roughly $1,863/year. Factor that into an offer.

Recomputed from the county assessment ($113,930, 1996 base year) × current millage. School millage is from the latest year certified by the Pennsylvania Department of Education (2025-26); districts adopt the next year's budgets each June, and we update when the state certifies the statewide file in the fall. Portals typically reprint the recorded 2026 bill. Pennsylvania does not reassess on sale. Estimate only. Verify with Montgomery County before relying on it.

Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
