New Haddonfield Listing: 421 E Cottage Ave, a 2024 Custom Home for $3.69 Million

Only one new home hit the market at a true Haddonfield address in our latest check, and it is a headliner. 421 E Cottage Ave is listed at $3,690,000. It is a five bedroom custom house built in 2024, and the listing agent is Joseph Anthony (Joey) Malcarney of Greenside Realty LLC.

The listing went live in Bright MLS on Nov. 8, 2026 (MLS #NJCD2130368). Here is what you need to know.

The basics

Five bedrooms. Five full baths and one half bath. Redfin and most MLS feeds put it at 8,000 square feet on a 0.44 acre lot. One feed shows 8,925 square feet of total living area, with about 6,635 finished, so ask the agent which number counts what. There is an oversized two car garage.

One MLS feed lists annual property taxes of $57,183. That is a number to confirm before you run your monthly payment.

What the listing highlights

The house sits at the end of a cul de sac and backs to wooded open space, per the listing. Inside: wide plank wood floors, an open kitchen and family room with two large islands, a walk in pantry, and Sub-Zero and Wolf appliances. The primary suite has a heated floor bath and a big walk in closet.

The lower level is where it gets unusual for Haddonfield. The listing describes a theater room, a home gym, and a spa area with a sauna and a cold plunge. Outside there is a pool and hot tub, a covered patio and a fenced yard.

The back story

This is not the house's first trip to market. Redfin's history shows it was listed in December 2025 and sold on Feb. 17, 2026, for $3,500,000. The new asking price is $190,000 above that sale, about 5% more, nine months later.

Why it is back so fast, we don't know. The listing doesn't say, and we won't guess. If you are a serious buyer, that is your first question for the agent.
