Mortgage shopping can be really frustrating. The rates change constantly; the refinance programs are always evolving and it's hard to be sure you have the most up-to-the-minute information. Read as much as you can about interest rates and the American economy. Look at sites like Bankrate.com to get information about mortgage rates and the low rates for the day. You can also check your local newspaper for local, up-to-date information. Make smart decisions about your long term financial goals, both in real estate and otherwise, by being informed.
