Points are prepaid interest and points lower the interest rate associated with the loan. Points are a percentage of your loan amount and 1 point is equal to 1% of your loan amount.
Credits (or rebates) are the opposite of points and are created by selecting higher rate options. Credits are applied against your third party fees and lower your closing costs.
Sometimes it does make sense to look at points or credits and we can help you decide what is best for your specific financial needs.
