Housing in Aetna Township consists almost entirely of single-family detached homes and manufactured housing. The real estate market is very affordable, with median home prices falling well below the national average.
The housing stock ranges from historic late-19th and early-20th-century farmhouses to mid-century rural builds and newer custom homes situated on large, multi-acre lots. Rental properties are somewhat scarce, as the area is heavily dominated by owner-occupied households. There are few to no large apartment complexes or condominium developments within the township limits.
