Britain's cheapest ever mortgage deal - which charged an astonishing 1.29pc fixed for five years - has been pulled after just nine days.
The mortgage was so low it charged borrowers a far lower rate than savers could earn if they tied up cash for a similar period.
The mortgage, offered by digital lender Atom Bank, came with a £900 fee and was available to those with equity in their property of 40pc or an equivalent deposit.
The nearest equivalent deal, from Barclays, is 36pc more expensive at 1.75pc.
The Atom Bank deal was withdrawn as of midnight last night.
Atom Bank refused to disclose how much money had been lent under the arrangement, but it is estimated that borrowers applied for loans totalling several hundred million pounds.
The 1.29pc deal, over five years, was comparable in price to the best available deals offered over a two-year term.
There was a fee-free version at a rate of 1.67pc over five years, also now withdrawn.
Borrowers with smaller deposits can still get a five-year fix for the same price as a best-buy two-year deal, as seen below - but these rates are also expected to be available for a limited time.
Experts said the banks was likely to be losing money on the loans, as part of its strategy to grow.
Atom Bank said its rates "are continuously under review and subject to change".
Borrowers can access Atom Bank’s mortgages via a panel of brokers. Customers need to request a list.
They can track their application via Atom’s smartphone app, which is also how they have to manage the mortgage.
David Hollingworth from London & Country, one of the brokers who offer Atom Bank's mortgage range, said his firm processed more than 400 applications to Atom since April 12.
The vast majority of those have been on the five-year rates and amounted to more than £100m of lending.
Mr Hollingworth said: "The rates available to those with a 25pc deposit start at 1.34pc, which is only 0.05pc higher than the withdrawn deal.
"Highlighting just how far ahead these rates are, those with only a 10pc deposit can get a five-year fix at 1.99pc, which is on par with other lenders’ rates for borrowers with substantially bigger deposits."
What is the next best five-year deal with a 40pc deposit?
Atom Bank customers were getting an incredible deal.
Those with a 40pc deposit borrowing £240,000 to put towards a £400,000 house would pay £936 a month plus a fee of £1,250 (£900 plus £350 valuation fee). In total this would cost £57,430 over five years.
Based on the same requirements, Barclays offers the next best five-year fix at 1.75pc. There is a £999 fee and monthly repayments are £988. A total of £60,575 will be repaid over the term.
What about a 10pc deposit?
Atom Bank customers with a 10pc deposit who require a mortgage of £360,000 for the £400,000 house would pay 1.99pc plus £1,250 in fees. Over the five-year term this would total £92,695.
The next cheapest loan is from HSBC. It charges 2.74pc and borrowers will need to pay a £1,262 fee. Total repayments come to £100,795.
