Millennials to Boomers: "Please update your homes." Boomers: "No!"

Millennials are worried they’ll inherit properties in need of major renovations and repairs, which could further hamper affordability, a new survey shows.

Young move-up home buyers are growing increasingly worried that baby boomers, many of whom are staying put in their current home, won’t update their properties and will pass down costly renovations and repairs to the next generation of owners, according to a new study from Morning Consult and Leaf Home, a national home improvement company.

Many baby boomers are choosing not to downsize, with 68% saying they’ve lived in their homes for 30 years or more, the study shows. Many in that group admit they’ve never done renovations or replaced major appliances—and they don’t have any plans to, either.

Researchers say this could become a nightmare scenario for millennials, who may inherit or purchase these “time capsule” homes. Younger buyers’ budgets already are stretched thin by high home prices and mortgage rates. It’s difficult for many to add pricey renovations to their homebuying budget.
