Basement Remodel questions, answered by experts

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
