Due to continually rising housing prices, we are finding a growing number of individuals are turning to prefab construction to buy an affordable home. At one end of that scale, we have found that many buyers are looking for low construction costs and are interested in prefab homes under $100k & modular homes under $100k.

While it is not impossible to find a prefab home that can be built for less than $100,000, it’s important to distinguish what is included in that number. On our site, we often use cost estimates that refer to turnkey housing prices, which include the cost of the finished home, site work, and permitting.

Due to the difficulty of finding a turnkey prefab home for sale under $100k, we have also included a few entries where the home itself is less than $100,000, though the total project cost might slightly exceed that amount. In those instances, we have made a note. Also, due to the highly regional markets of many of the companies on our list, we have noted which geographies they serve.

It is also important to note that prefab construction encompasses a range of construction styles and simply refers to a home that is built with components that are built offsite. So when looking for affordable prefab homes, this can include modular homes under $100k, manufactured homes under $100k, kit homes under $100k, and even tiny homes under $100k (specifically, tiny homes on wheels).
