Smaller home renovation projects with a big impact on aesthetic appeal will pack the biggest bang for the buck in 2019, a new report finds.

Less expensive but highly visible projects, like a new garage door or a minor kitchen remodel, top "Remodeling" magazine's annual Cost vs. Value report.

"When you are buying a property, one of the things you want to check off is, do I have a functional kitchen I can live with before I make it my own?" said Clayton DeKorne, chief editor of the JLC Group, which includes Remodeling magazine.

Conversely, spending hundreds of thousands of dollars on a master suite addition or a major kitchen revamp may make you and your family happy, but it won't necessarily lead to a big payday when it comes time to sell, the report finds.

While such major projects may enhance comfort or make a home more functional, you might be lucky to get a bit more than half your money back.

"That is because of all the decision making that goes into a project like that from the homeowner," DeKorne said. "There are so many particular or subjective decisions that go into that."
