The housing market has been booming in 2021, thanks to low interest rates and motivated buyers. In many demographics, this has led to low inventory and sky-high asking prices. If you can’t seem to find your dream home for sale, purchasing land and having a house built is a great option. 

Of course, building a house comes with a lot of choices, contractors, permits, unforeseen costs, and waste. Prefab homes offer a more sustainable, and often more affordable, alternative. These prefabricated modular homes are built off-site in a factory, reducing water usage and material waste, and then shipped to your build site for installation and assembly.

Curious? We’ve rounded up nine affordable prefabs you can move into in as little as a few months.

Why should you buy a prefab home? 

If you’re thinking about going prefab, chances are you’ve been crunching some numbers. According to Home Guide, the average modular home costs between $80 and $160 per square foot to build and install. Meanwhile, the average cost to build a house in 2017 was $153 per square foot. So while you can purchase a fancy prefabricated home that rivals the cost of a regular house, there is lots of room for savings.

Some of that savings comes from building permits, which are less expensive for modular homes. And aside from costs, prefabs can also be built more quickly and with less waste, thanks to their standardized format, and they're usually built with superior insulation that'll save on energy usage down the line. Convinced? These nine affordable prefab homes are move-in ready.
