While buying an existing home costs less and saves time, some prefer to build a new one from scratch with the help of a local home builder. Sure enough, the market for custom homes is growing at a modest rate of 4% last year, with the National Association of Home Builders citing high mortgage rates as a major factor. Additionally, Residential Design finds that the custom home construction market “is less sensitive to the interest rate cycle than other forms of home building.”
It’s only a matter of finding a capable company that will help make the most of the time, money, and effort invested without compromising on quality, longevity, or energy efficiency.
