Finding a trusted builder is the first step toward realizing your dream of owning a modular house. Unfortunately, It can be difficult to identify expert builders because of the proliferation of misinformation on the internet. To save you the trouble of sorting through a myriad of information, we compiled a list of some of the best prefab home builders in New Hampshire to help you choose a partner in building your dream home. 

Why Build a Prefab or Modular Home in New Hampshire?

You can’t go wrong with New Hampshire if you want a place to settle. According to Wallethub, New Hampshire is 6th best state to live in. New Hampshire is considered one of the top 10 states in terms of safety, health and education, and economy. However, a house in New Hampshire is more expensive than similar ones in other states, which is why a modular home is an attractive and affordable alternative. 

Prefab houses are faster to build than traditional houses, so you can move in quickly. If you are renting a temporary place while waiting for your house to be built, a shorter construction time can help you save on rental costs. 


One disadvantage of building a modular home in New Hampshire is its high property tax. At 1.77% of a property’s assessed value, New Hampshire has the fourth-highest property tax in the country. However, since these homes are cheaper to build, your property tax obligations will still be lower than those who own traditional houses. 

New Hampshire is a popular summer destination so prepare for traffic congestion when tourists start pouring in. Memorial and Labor Days see traffic gridlocks that make daily errands challenging. The best thing to do is to plan your activities during the summer months to avoid getting stuck in traffic.
