Baby Boomers Are Leaving Florida for a Surprising New Beach Haven

Delaware’s coastal communities are emerging as a surprising new magnet for retirees, as Baby Boomers increasingly look past long-favored havens like Florida and Arizona in search of a more affordable place to enjoy retirement.

Since 2020, Sussex County has welcomed more than 40,000 new residents, pushing the population of the largely rural seaside county up 17 percent — roughly five times faster than the national growth rate, according to Bloomberg.

That wave of newcomers has helped make Delaware a standout in America’s retirement migration boom. Census Bureau figures show the state’s 65-and-older population has climbed 23 percent since 2020, the biggest increase recorded anywhere in the country.

A major reason behind the shift is Delaware’s growing reputation as a financially attractive retirement destination.

Florida once dominated the conversation for older Americans seeking sunshine and savings, but surging home values and steep property insurance premiums have made retiring in the Sunshine State far less budget-friendly than it used to be.

Delaware, by contrast, still comes in slightly below the national average for overall costs and remains notably cheaper than nearby high-cost states such as New York, New Jersey and Maryland, based on estimates from the US Bureau of Economic Analysis.

Its tax structure adds to the appeal: Delaware has no sales tax, and homeowners can often find property tax bills that are far lower than those across state lines.

That combination has proved especially enticing to retirees from the Northeast. Some homeowners trading New Jersey for southern Delaware have swapped annual property tax bills of about $18,000 for payments closer to $1,500, Bloomberg reported.

Jason Gerstenberger, an independent insurance broker specializing in retirement income and wealth transfer, said retirees need to look at more than just state taxes when deciding where to move.

‘Retirees have to look at the full picture when pivoting to a fixed income,’ he said, pointing to property insurance, natural disasters and leisure costs.

Delaware property insurance averages around $1,374 annually compared with roughly $7,100 to $8,500 in Florida, based on recent surveys, Gerstenberger said.

‘Florida’s insurance bill alone can be larger than the entire state income tax bill a typical retiree would have in Delaware,’ he said. ‘People crunch the numbers and Florida loses a bit of its luster.’

The newcomers are also significantly older and wealthier than longtime residents.

Sussex County’s median age reached 53.2 last year, nearly five years higher than it was in 2015 and almost 14 years above the national average.

Families moving to Sussex from other states earned more than $136,000 annually, according to the latest available Internal Revenue Service migration data, compared with less than $92,000 among existing residents.

The pandemic accelerated the trend, with some homeowners turning beach vacation properties into year-round residences.

Others are drawn by the area’s proximity to major cities including New York, Philadelphia and Washington, allowing retirees to remain relatively close to family while enjoying a quieter lifestyle.

Towns including Lewes, Rehoboth Beach and Milton have seen an influx of older residents, while developers have responded by building large numbers of new homes farther inland.

Much of the new construction is marketed specifically toward people aged 55 and over.

But southern Delaware is no longer uniformly cheap.

The average price of a home sold in Sussex County was around $471,000 during the three months through June 2026, according to Alexei Morgado, a Florida real estate agent and founder of Lexawise.

‘Southern Delaware, especially the part near the coast, can no longer be said to be affordable,’ he said.

The population boom is also putting pressure on the very amenities that attracted retirees in the first place.

Sussex’s roads, hospitals, schools and other services are struggling to keep pace with the rapid growth, while increasing development has fueled complaints from longtime residents and newcomers.

Traffic has become an increasingly visible problem, particularly along Route 1, as tourists heading to the beach compete with residents navigating their daily commutes.

However, despite the rapid acceleration of infrastructure, healthcare remains a major concern.

Sussex County was already classified as medically underserved before the recent population surge, and the number of residents aged 80 and over is projected to more than double by 2040.

Gerstenberger said the healthcare system is struggling to keep up with the influx.

‘There’s 130 primary care doctors for over 271,000 people,’ he said. ‘Most people moving in have no idea of how inundated the healthcare system is here due to the boom.’

He said the biggest concern is that new housing is being approved faster than doctors and other healthcare workers can be recruited.

‘New buildings are getting approved faster than doctors are getting recruited,’ he said, warning that the shortage could hit the growing Medicare population particularly hard.

Beebe Healthcare, the county’s main hospital, has responded by expanding its workforce and facilities. It has hired more than 50 doctors in four years, a 47 percent increase, and launched a family medicine residency program.

But the growing population has created another problem: finding enough workers to support the expanding healthcare system.

For every new doctor, the hospital needs roughly six additional support workers, according to Bloomberg, and many of those employees struggle to afford housing close to their jobs.

The influx has also transformed the local economy.

The number of business establishments in Sussex County jumped 49 percent between 2020 and 2025, according to Bureau of Labor Statistics data, while nearly 100 restaurants have opened.

But the rapid development could eventually threaten the qualities that made the area attractive to retirees.

Morgado said the beach access, relaxed lifestyle and relatively affordable cost of living are the region’s biggest draws, but those advantages could deteriorate if growth is not properly managed.

Sussex County’s population reached an estimated 277,140 in 2025, up from 237,378 in the 2020 Census, while the county issued 3,885 building permits in 2025, according to Morgado.

The county’s growth is now becoming a major political issue, with development and concerns over overcrowding taking center stage in local elections.

Then there are the concerns about property taxes.

Sussex County recently completed its first property tax reassessment since 1974, and Gerstenberger said some tax bills along the coast jumped between 200 and 500 percent.

There is another tax catch for newcomers: Since 2018, retirees have had to live in Delaware for 10 years before becoming eligible for the state’s Senior School Property Tax Credit.

Despite the concerns, the area’s fundamental appeal remains strong.

‘The main reasons why people go there in the first place aren’t going away just because more people move in,’ Gerstenberger said. ‘The beach is still the beach.’

Morgado expects the migration to continue, with development increasingly moving inland as coastal communities become more expensive and crowded.

‘Five to ten years from now the beach towns will be totally full so the growth will spill inland,’ he said.

‘The farm fields everybody sees while driving in and out of town will all be subdivisions.’

The challenge, he said, will be expanding the region while preserving the qualities that made it attractive in the first place.
