Multi-generational homebuying is surging—and it's not just a national trend. In 2025, 17% of homebuyers reported they are purchasing a property to share with parents, adult children, or extended family, according to the National Association of Realtors (NAR). In South Carolina, this trend aligns with broader housing pressures: the state has added more than 30,000 households since 2018, but housing supply has not kept up, according to the SC Department of Employment and Workforce.
Why SC Families Are Choosing Multi-Generational Homes
Cost Savings Are the Biggest Factor
According to NAR, 36% of multigenerational buyers in 2024 said “cost savings” was the primary reason for buying together—up dramatically from 15% in 2015.
By pooling incomes, families can afford a larger or higher-quality home than they might on their own.
Flexible Living Designs Are in Demand
Homes with dual master suites, separate entrances, guest homes (“casitas”), and private in-law areas are becoming more common, especially in thriving SC markets like the Lowcountry.
These layouts give families both shared and private spaces—ideal for caregiving, work-from-home arrangements, or renting out a portion of the property.
Resale Appeal & Investment Potential
Multi-generational homes are more attractive to a broader buyer pool. As more families look for flexible living, having extra living space or an accessory dwelling unit (ADU) could make a property more marketable in the future.
For investors, a house designed for multiple generations can be leveraged for rental income while still serving as a primary residence for family.
Long-Term Wealth Building
By living together, generations can contribute to mortgage payments, utilities, and maintenance—helping build joint equity.
It’s not just about saving now: this structure can form part of a generational wealth strategy.
Challenges to Consider
Financing Complexity: Lenders may require co-ownership agreements or joint loan applications. Be sure to talk to a mortgage broker who understands multigenerational purchases.
Permitting & Zoning: Some areas of SC may restrict accessory dwelling units. Make sure you check local zoning laws before planning a guest suite or separate living structure.
Design Trade-offs: You’ll need to balance shared vs. private space to make the home work for everyone.
Future Flexibility: Think ahead—how will the space be used if family circumstances change? The more flexible the design, the more value you’ll ultimately get.
Why Now Is a Good Time to Buy
The housing supply gap in SC gives multi-gen buyers leverage: as more households are created but homes are not built fast enough, finding flexible, family-friendly properties is a strong opportunity.
With mortgage rates still challenging, sharing costs with loved ones makes homeownership more achievable.
Demand for homes with adaptable living spaces is rising—making these types of properties potentially more valuable down the road.
