Refinacing your mortgage can allow you to take cash out of the equity which you have built in your home. You can pay off your higher interest debts and pay all of your debts at a lower interest rate. This will allow you to save money on a monthly basis and achieve your financial security.
These days most people request a Good Faith Estimate (GFE), but have no clue what to look for on the GFE. Make sure you request a GFE that has ALL fees estimated and disclosed. This includes: origination points, processing, lender, appraisal, title, escrow... ALL FEES... especially the Yield Spread Premium or YSP.
When refinancing, don't take the first offer that comes around. Instead you should actively compare both interest rates and lenders.
When it comes to lowering your rates you will need to weight the benefits of having a lower rate vs. paying points up front. You may end up paying a lot more depending on your choice and how long you plan on keeping your mortgage.
