Building a new house can be very exciting. When you are in charge of creating your own place to live (or to sell for somebody else to live in), you’ll be able to control many of the most important details, including the aesthetics, the architecture, its key features, and—at least in some situations—its location.

However, one of the reasons many people choose to live in a pre-built home rather than build one of their own is that, generally, building a home from scratch can be very expensive. According to recent estimates, the average cost of building a new home is 250K, which is just a little bit higher than the average cost of a new mortgage. However, there are still plenty of situations in which building a home from scratch might end up being the cheapest option you have available.

About half of all people building a home from scratch will spend between 120K and 450K, not including the cost of land. Of course, if you are looking for a home with a ton of crazy features, the costs can be considerably higher.

But what if you are looking to build a home for as little money as possible? Suppose you are looking to build a home for less than 100K—is that even possible?

The short answer is yes. But, as you’d probably imagine, if you are hoping to build a new for as cheap as you possibly can, you are going to need to be willing to make a few sacrifices.
