You are fortunate in the current market that new construction prices are equivalent to the newer existing homes and even building a modular home. Make sure to use a reputable builder; I would advise going to look at other homes he/she has built and assure yourself of quality construction. Make sure that the quote includes all the aspects of building the home, including the cost of a lot, a well and septic if public water and sewer are not available, grading the lot (which can be a significant cost on a mountain lot that is not level), and putting in a permanent foundation such as a slab, a crawl space or basement. These costs can add significantly to the cost of the home. Using a Realtor who knows the best builders in the area and can walk you through each step of the process can make this a pleasurable experience rather than a time of anxiety and pitfalls. The Realtor can coordinate with a top-notch loan originator who will set up the construction loan and the one time closing to your best financial advantage. So, in answer to your question, the new construction square foot cost will vary by what is included. If it is the home only, without all the other costs mentioned above, it can be less than $100/sq ft. Adding in the other costs will take it over that and then it will need to take into account the upgrades you want such as granite countertops, jet tubs, and hardwood floors. The builder can help you with a basic model as well as your specific upgrades. Once you sit down with your Realtor and Builder, your questions will be answered and your dream will begin to take shape. Another traditional rule of thumb: the first time a home is sold, the owner generally realizes the most profit. If you have a good experience building your new home, it can be very worthwhile!
