Unless you choose a lender’s standard variable rate mortgage you can expect to pay an arrangement fee for your mortgage. Arrangement fees vary wildly, and may be expressed as a fixed fee or as a percentage of the loan. This means it is difficult to give an accurate estimate but it is not unusual to pay something in the range of £500 – £2,000 or more.
You will usually have the choice of paying the arrangement fee up front or adding it to the loan. Adding it to the loan may ease your cash flow but will cost you more as you will pay more interest.
