The Kind of House Wilmington & Hockessin Buyers Are Willing To Pay More For
That spare room on the main floor. The finished basement with a kitchenette and its own entrance. The bonus room you've been using for storage.
To you, it's extra space. But to a growing pool of buyers across New Castle County — from Wilmington to Hockessin, Newark to Greenville — it's the reason they'd pick your house. Here's why: multi-generational homebuying is on the rise, and the Delaware/Southeastern Pennsylvania border region is right in the middle of this shift.
Millions of Families Are Living Multi-Generationally
The number of multi-generational households is climbing nationwide. That's when 3 or more generations live under one roof. Data shows those households grew from 3.2 million to almost 4 million between 2014 and 2024, according to Realtor.com.
And each year, more people — including families throughout New Castle County and the Hockessin/Wilmington area — are shopping for a larger home that fits their combined needs, whether that's aging parents relocating closer to family, adult children saving up, or households sharing space and costs in a tight housing market.
While the appetite for this type of house is rising across the board, data from USAFacts shows multi-generational living is more common in some states than others. Delaware and Pennsylvania both show meaningful demand, meaning the pool of buyers looking for a house like yours in Hockessin, Wilmington, or the surrounding New Castle County suburbs could be even bigger than you'd think.
There's a real market out there for larger homes with room for multiple generations, especially with affordability still tight across the Delaware Valley. And if you own a house like that, it's in demand.
Multi-Generational Houses Sell at a Premium
And that extra room carries real value with the right buyer. According to Realtor.com, in 2025 the median asking price for a multi-generational house was $709,000 — roughly 65% higher than the $429,900 median for a standard house.
Some of that is simply size. But compare multi-generational homes to regular homes with the same amount of square footage, and they still come out on top — $262 per square foot versus $215.
That's a 22% premium you could command for special features like in-law suites, second kitchens, and separate entries — the kind of layouts common in larger Hockessin and Greenville estates, as well as Wilmington-area homes with finished walkout basements or accessory suites.
When you sell in the Wilmington/Hockessin/New Castle County area, this could help you walk away with more money in your pocket, especially when your agent highlights your home's multi-generational-friendly features — a private in-law suite, a second kitchen, or a separate entrance — in your listing.
And Local Buyers Aren't Getting Sticker Shock
Even with slightly higher price tags, buyers aren't flinching. Multi-generational houses drew 13.5% more online views than standard ones, and they still sold just as fast — in about 59 days — per the same Realtor.com report.
Hannah Jones, Senior Economic Research Analyst at Realtor.com, explains that in inventory-constrained markets — a familiar story across New Castle County and the Delaware/PA border suburbs — there's a real mismatch between what buyers are looking for and what's actually available, making this type of home a significant asset for sellers.
Basically, when buyers want something very specific — like a Hockessin home with an in-law suite, or a Wilmington property with a private lower-level apartment — the house that checks the box tends to stand out.
Bottom Line
Your multi-generational-friendly, or simply larger-than-average, home in Wilmington, Hockessin, or the surrounding New Castle County area might meet criteria a lot of buyers can't find in a standard listing. That's what gets attention. And offers.
So, let's chat about what your home's extra space could get you in today's market.
