If your property value reduces and you refinance up to 80% of the reappraised value, your original mortgage amount may be higher than this amount. Thus, the new loan will not be sufficient enough to help you pay down the existing one.
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.
If your new mortgage rate seems too good to be true then it probably is. Check for hidden fees in your mortgage that will make up that suspicious difference.
Carefully review the estimated closing costs. If you decide to lock in the rate, the lender will send you a "good faith estimate" of your closing costs within three days. Go over the numbers carefully, and compare them to the ones that appear on the final settlement statement (the HUD-1) from your previous mortgage.
