Millions of Baby Boomers are planning move over the next several years – everyone knows this. But it could mean big things for agents working in Miami.

There are three reasons most homeowners between the ages of 61 and 90 want to sell their home and move elsewhere: they want to be closer to friends and family; they want to downsize; or they’re planning on retiring. And as Sue Rossi, broker and owner of the Illinois-based RE/MAX 2000, wrote in a recent Builder article: “That’s not new news.”

The news is how widespread this age group is.

In, 2014, when the U.S. Census last released population data, an analysis from Pew Research Center discovered that 97 percent of counties saw an increase in their 65-and-older population since 2010.

By state, the 65-and-up population varies (see our table at the end of this article). It makes up over 19 percent of Florida’s general population.

Florida is the oldest state in the U.S., and likewise, Miami is one of the top 10 oldest cities. In 2010, it’s 60-and-up population accounted for 19.1 percent of the general population, according to Census numbers. And considering the rapid growth of Miami-Dade County’s 55- to 59-year-old population (35.3 percent from 2000 to 2010) and 60- to 64-year-old population (27.5 percent from 2000 to 2010), we can assume the city’s population will continue to age over the foreseeable future.

Why this matters

The reason these figures are so important, is because 27 million Baby Boomers plan to eventually move – and 13 percent of them within the next four years.

Older buyers are particular in ways much different than their younger counterparts. They want homes and neighborhoods with very specific amenities, like close bus stops, drug stores and churches.

“The decisions the nation’s Baby Boomers and other older homeowners make will have an enormous impact on the demand for housing and new mortgage credit for the foreseeable future,” said Dave Lowman, executive vice president of single-family business at Freddie Mac. “Whether they buy new homes or decide to refinance and renovate their current ones, the size of this generation, and the fact that they hold approximately $8 trillion of the nation’s home equity, makes it very important that we watch what they do.”
