Home Building questions, answered by experts

You can’t add home addition costs to an existing mortgage, but you can include them in a new mortgage if you take out a rehab loan. Rehab loans—FHA-backed 203k loans and conventional rehab loans—are for more than the value of a property, and the excess is meant to cover the cost of a renovation or home addition.

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

Since building up tends to provide useful bedrooms and other extra spaces without the need to do a lot of foundation work and cut into your yard, second stories tend to have better ROI—up to 65%—than other kinds of additions. But ROI will depend on the type of rooms you are planning and what your current house has. It’s not a very reliable way to judge the success or failure of a project, so consider other factors as well.

Some, but not all, home improvements are tax deductible or offer other tax benefits. For example, if you make green improvements to your home, such as installing a heat pump or solar panels, you may qualify for a tax credit. You may also deduct the cost of home improvements you make to improve the accessibility of your home or to allow yourself or another resident to age in place.

Framing tends to be the longest step in the construction process, especially for larger homes. It takes anywhere from one week to a couple of months, depending on the house size, the number of people on the construction crew, and the time of year. The design stage often takes a long time, too. Some people spend months or even years contemplating their house’s size, layout, and materials before construction begins.
