This mortgage calculator is provided by Charters. Charters work with Mortgage Decisions to give our clients access to expert mortgage and protection advice. Mortgage Decisions have access to over 12,000 mortgages from 90+ lenders so they can find the right mortgage to suit your individual needs. Your home may be repossessed if you do not keep up repayments on your mortgage. There may be a fee for mortgage advice. The actual amount you pay will depend upon your circumstances. The fee is up to 1% but a typical fee is 0.3% of the amount borrowed.
