If you want a home improvement loan, here's something you want to avoid at all costs. Suppose you've had your mortgage for years. The interest rate is low and the monthly payments fit nicely into your budget, but you could use some extra money for a home improvement project. A lender calls to talk about refinancing, and using the availability of extra cash as bait, claims it's time the equity in your home started "working" for you. You agree to refinance your loan. After you've made a few payments on the loan, the lender calls to offer you a bigger loan for, say, a home improvement project. If you accept the offer, the lender refinances your original loan and then lends you additional money. In this practice-often called "flipping"-the lender charges you high points and fees each time you refinance, and may increase your interest rate as well. If the loan has a prepayment penalty, you will have to pay that penalty each time you take out a new loan.
