Work out what you can afford

Calculate your total costs
It's important to look beyond the headline interest rate and take into account all the fees you have to pay. Arrangement fees, mortgage valuation fees and insurance fees may all apply, and these costs should be added to your calculations.
Be wary of extra interest
Instead of paying your mortgage fees upfront, you may have the option of adding them to your loan. While this can be a helpful option if you're low on cash, be aware that it will result in you paying extra interest on these fees over time.
Avoid early repayment charges
By avoiding mortgages with early repayment charges, you can switch to a better deal without charge after the initial rate has ended. Make sure your mortgage is also portable, so you can keep the same deal if you move house.
Get good, unbiased advice
If you decide to consult a mortgage broker, make sure you use an independent company or adviser. An independent broker can help you find a deal that best suits your personal circumstances. But some deals are only available directly from the lender, so always do your own research as well and compare your findings with the recommendations your adviser gives you.
