Home Building questions, answered by experts

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

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.

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.

The number of rooms a guest house should have really depends on your needs. A small guest house might only need one bedroom, a bathroom, a living room, and a kitchen. Larger units may have multiple bedrooms and bathrooms. Your local building codes may limit the number of rooms or square footage you can have in a guest house.
