Nationwide increased the minimum deposit required to secure its best rates from 10% of the value of the property to 25%. With the average price of a London house now more than £300,000, buyers will have to raise at least £75,000 up front. It is a major blow for first-time buyers in particular. The clampdown by Nationwide comes as banks and building societies tighten lending conditions following the credit crunch. Until today, borrowers needed only to raise a deposit of 10% or more to take advantage of Nationwide’s best rates. They now need 25% or more - or face an extra 0.2% of interest. The rise only affects new borrowers and wipes out the benefit they would have enjoyed following this month’s cut in interest rates by the Bank of England. Nervous rival lenders are set to follow suit as they chase margins rather than market share.
