To refinance a mortgage is to get a new loan for the home or business, typically at a lower interest rate. This new loan is then used to pay off the first mortgage and continue forward as the lone mortgage for the property. Many people choose to refinance their property in order to lower their monthly payments, take out equity, or take advantage of low interest rates. But refinancing can have major disadvantages, too, so it’s a good idea to work with a real estate lawyer who is experienced in the area of refinancing.
