Mimi Collins’ Restored Hinsdale Mansion Listed for $7M

A fully rehabilitated Hinsdale mansion that was saved from demolition two years ago has hit the market.

Spanning more than 7,000 square feet at 420 South Park Avenue, it is listed for just shy of $7 million, Crain’s reported. Mimi Collins of Jameson Sotheby’s International Real Estate owns the house and is the listing agent.

Hinsdale has been grappling with a demolition spree for decades, and a quarter of homes in the town have been torn down and replaced since 2000, the outlet said. This trend has prompted preservationists and officials to take action to protect historic homes in the southwest suburb.

Collins bought the house for $1.8 million in November 2021, and the rehabilitation project shows that “you can make these old homes livable now.”

The home needed major structural and aesthetic upgrades. Rehabbing it involved restoring windows, upgrading utility systems, revamping the exterior stucco and redesigning interiors to blend modern conveniences with the home’s vintage appeal. The outcome underscores the mansion’s transformation into one of Hinsdale’s most enviable homes.

“It’s hard, but it’s worth the effort and the money because these houses are what makes Hinsdale special and charming,” Collins told the outlet.

A recent effort to demolish a house four blocks away was temporarily halted by the town’s historic preservation commission, although the village board has the ultimate decision.

Hinsdale’s historic district also features a 19th-century home that was saved from demolition by a Cincinnati couple in 2021.

When Collins acquired her property, it had lingered on the market for years. It was listed for nearly $3.8 million in 2015.

The restored Park Avenue residence ranks as Hinsdale’s second-most expensive property, trailing a County Line Road mansion priced just below $10 million.
