The U.S. is experiencing a significant demographic shift, with the population aged 65 and older expected to double to 80 million by 2040, representing about 20% of the total population. This trend, dubbed the 'silver tsunami,' is impacting areas nationwide, including Sussex County, Delaware.
Sussex County has seen a substantial influx of new residents, particularly baby boomers, drawn by its desirable beach towns, lower housing prices, no state sales tax, and reduced property taxes compared to neighboring states. Since 2020, the county's population has grown by 17%, five times the national average, and Delaware leads the nation with a 23% surge in its senior population during the same period.
However, this rapid growth has placed a strain on local infrastructure. Roads, hospitals, and retail services are struggling to accommodate the increased demand, leading to complaints about overdevelopment from both long-time residents and newcomers. While Sussex County offers a slight advantage to homebuyers with the highest median home prices in the state ($575,000 median list price), it also leads in inventory, longest time on market (168 days), and months of supply (3.7 months), indicating more buyer negotiating power.
For many seniors, retirement in the area has brought challenges such as everyday annoyances, traffic congestion, and significant stress, compounded by difficulties in accessing healthcare with long waits for medical and dental appointments. This has prompted some residents, like retired professor Joe Pika, to form coalitions advocating for slower growth and smarter municipal planning.
Despite these issues, affordability remains a key factor attracting seniors to southern Delaware, which is less expensive than the U.S. average and significantly more affordable than nearby states like New York, New Jersey, and Maryland. Land-use regulations and the development of communities marketed to those 55 and older, often on former farmland, are contributing to this population growth.
Reverse mortgage professionals see an opportunity to assist seniors looking to relocate by leveraging their home equity. Homeowners aged 62 and older held a record $14.92 trillion in home equity in the first quarter of 2026. Reverse-for-purchase loans, which allow seniors to unlock equity to buy a new home without a mandatory mortgage payment, are underutilized due to a lack of awareness. While federally insured Home Equity Conversion Mortgages (HECMs) for purchase represent a small fraction of the market, proprietary reverse mortgages have seen significant growth, with originations soaring by 81% in 2024 and 118% in 2025.
