When comparing mortgages, it's important to look for the best mortgage rates but don't get caught out by additional mortgage fees that can end up making your mortgage more expensive. Not all of the following charges will apply to all mortgages, but some of the main costs involved with getting a mortgage include: Broker fee - Some mortgage brokers charge for their services, but if you compare mortgage rates with Mojo they offer their expert advice free of charge. Booking fee - This is a non-refundable upfront charge that secures your loan when you make a mortgage application. Arrangement fee - Also known as a completion fee, this is the amount you pay your lender to set up your mortgage. This can typically cost up to £2000, which you can choose to pay upfront or add to your mortgage. If you decide to add the fee to your mortgage, remember that you'll have to pay interest on it. Valuation fee - The lender values your property to ensure it's worth the amount you're borrowing. Some mortgage lenders won't charge a fee, others will, and the cost varies depending on the value of the property. Solicitor fees - Is the amount your solicitor charges to handle the legal side of buying the property. This includes services such as transferring title deeds and arranging contracts. The fee can be anywhere from £850 - £1,500.
