A repayment mortgage is one where the borrower pays the amount of capital borrowed plus the interest on the loan. This is the most straight forward type of mortgage, as borrowers know exactly what they are paying back – the amount borrowed plus interest. If you intend to move home with this type of mortgage, you will most likely have to arrange another mortgage with a term of 25 years or so, in order to keep your payments affordable. You usually do not require to have an additional investment policy for this type of mortgage, so are not investing in the stock market.
