If there are only a few years left on your current loan, it's no use refinancing with a long term loan. You may need extra cash but with a long term loan, you'll end up paying more for the entire loan term.
If you want to make sure the interest rate your lender offers you is the rate you get when you close the loan, ask about a mortgage lock-in (also called a rate lock or rate commitment). Any lock-in promise should be in writing. Make sure your lender explains any costs or obligations before you sign.
Use a mortgage broker. A mortgage broker will show you mortgage products from different banks and mortgage providers. Pick a mortgage broker carefully. If the broker works directly for a company that offers financial products, make sure he shows you clearly why one of these products is better. Mortgage brokers also get a commission on their sales. Find out what the broker's services include and if he charges any fees. Many brokers do not charge fees beyond their commission. Also check the broker's credentials.
Be Proactive. Your loan representative should keep in contact with you even if there isn't any action on your loan. But do your part to keep the lines of communication open as well. If you don't hear from your loan representative for a few days, pick up the phone and ask for an update. The old adage that the squeaky wheel gets the grease definitely applies in this situation.
