Yes, 6.5% is a great rate but there is more to it than that.
Make sure you understand all the terms of the loan. Interest rate is only one cost of the loan. Lenders do a good job disguising those costs. If you're not aware of them, you may think you're getting a good deal when you really aren't. How many points are being charged? If you're getting charged 4 points, all of a sudden 6.5% isn't so great. What about all of the other costs (i.e. processing fee, application fee, underwriting fee, etc.)? The best way to compare is using the APR.
The annual percentage rate (APR) is the effective rate of interest that is charged for the loan. The Truth in Lending Act requires lenders disclose the APR on all loans. Its purpose is to allow consumers to shop for credit by comparing the fine print. In the absence of such requirements, it would conceivably be possible for a lender to misrepresent a loan with a 20 percent effective interest rate as a 10 percent loan. However, the APR can be calculated in different ways and can sometimes cause rather than eliminate confusion.
Bottom line is, although the APR may not be perfect, it's a far better way to compare loans than just comparing the simple interest rate.
Hope this helps. Good luck to you.
