If you have substantial savings, it will probably cost a lower percentage of interest to use your liquid assets than to obtain a loan, but better be sure!
Obtain a home equity loan. Many institutions offer very attractive interest rates for loans to remodel your home. Remember, if you plan to sell your home within a relatively short period (three years or less) you may find that the interest paid is greater than the amount of value added to your home's sale price. When talking to your loan institution, request an amortization document to demonstrate the actual cost of the money you are borrowing over the period of loan.
It may be worth hiring a real estate professional or to get an accurate estimate of your home's market value, including the new kitchen you have planned.
Use a credit card. Many companies that sell products used for home remodeling also offer credit cards. The interest rates and terms vary. Some may offer "no interest until……" or other special arrangements. The advantage of using a such a credit card lies in the ease with which you may exchange merchandise if you make a mistake or are not satisfied with the products you purchase using it.
Whatever financial route you choose to the kitchen of your dreams, rest easy! You will have substantially increased the value of your home, and made it easier to use and a more attractive space for you and your family day after day!
