Ask the lender or broker for a comparison of the up-front costs, principal, rate, and payments with and without this rate trade-off.
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.
Don't escrow taxes and insurance. Unless you're undisciplined, avoid putting monies in escrow to cover your property taxes and homeowner's insurance. There's usually a fee for this privilege that runs under 1 percent of the loan amount, in states where it's allowed. "Paying the fee will allow you to time your tax and insurance payments to your benefit," says Bank South's Steve Austin. For instance, you may be able to prepay taxes that are due next year and use those payments to reduce your current tax bill. Moreover, you get to hang onto your money longer. That may be an advantage when interest-bearing accounts start paying more.
Be specific about the loan you want. The more precise you are, the easier it will be for a loan officer or mortgage broker to find the best rate. For example, do you want a 15-year or 30-year mortgage? Do you need a "jumbo" mortgage (more than $333,700)? Are you willing to pay points to reduce the interest rate? The answers to these questions will depend on several factors, including when you plan to sell the house and how soon you want to retire your debt. Only you know the answers, but the sooner you know them, the better.
