Find and compare tracker mortgages online in just a few minutes
The Base Rate of interest is how much it costs banks to 'buy' money. It is set by the Bank of England and depending on how the economy is behaving they'll make this cheaper or more expensive.
Following this means your interest rates will go up and down in line with the performance of economy, so when times are tough your repayments should be smaller and vice versa should the economy be booming.
It's simply the base rate, plus a charge to you on top that will be pre-agreed for set amount of time. For example, if your tracker mortgage is the Base Rate +2%, and the Base Rate rate is 1%, you will pay 3%. If the Base Rate rises to 2%, you will pay 4%.
Tracker mortgages can be a risk - if the Base Rate rises, your payments will rise accordingly. However, if they fall, so will your mortgage repayments.
Some tracker mortgages are capped - this means that there is a limit to the maximum amount your mortgage rate can rise to, irrespective of how high the Base Rate goes.
If the Base Rate goes down, you also have the opportunity of paying more of your mortgage off each month. That way, you are taking advantage of the low rates and minimising the total amount of debt payable if the rates go up.
A variable rate mortgage will follow the Standard Variable Rate of the bank which has made the loan, whereas a tracker mortgage follows the Bank of England's Base Rate.
Most mortgage lenders will provide a tracker mortgage as one of their options alongside variable and fixed rate mortgages.
Is there a catch with tracker mortgages?
Although there's no catch per se, be aware that if interest rates rise so do your mortgage repayments. Therefore, you may find budgeting for your monthly bills more difficult as the rate at which you pay could change regularly.
That said, you are reliant on the Bank of England rather than changes your lender is likely to make in reaction to interest rates, so you can monitor changes with more clarity.
The Bank of England makes their decision on whether the bank charges change and by how much on the first Thursday of every month.
It is strongly dependant on the strength of the economy and the rate of borrowing nationwide.
Most banks will allow you to change your mortgage, but many will charge an early repayment charge for leaving before your mortgage term has ended.
