But despite this the new mortgage has been criticised by some in the industry.
Nick Hopkinson, Director of Property Portfolio Rescue (PPR) said: "Nationwide’s 125% mortgage offering amounts to assisted financial suicide for today’s borrowers – sheer madness for both them and the lender.
"I expect the purpose of this latest offer is more of a marketing stunt than a feasible product, as the loan criteria and small print will make it almost impossible to access – wasting everyone’s time with false hope."
