Depending on the number of years you have paid your mortgage, you may have enough equity built up. If that is your case, a cash-out will be the best option to pay for home improvements.
However, if you do not have that much built-up equity, you can consider using a renovation refinance loan. The loan is designed based on the value of your home after you complete your renovation project. That means you can still access finances to complete your remodeling without tapping into your equity.
