Remortgaging to raise money for home improvements can be an advanced technique to finance your remodeling project when mortgage interest rates are low. There are other things to consider.

Because you'll be raising the size of your remortgage for home, your loan-to-value ratio may rise. If you have a mortgage of £100,000 and your home was worth £200,000, you would have a loan to a value of 50% and be eligible for the excellent mortgage deals. However, if you require £50,000 to build an extension, your loan value will increase to 75%, and your remortgage options will become much more expensive.
