Mortgage approvals for home purchases increased to 73,500 in February, from 71,300 in January, and their highest level since January 2014, data from the Bank of England showed.
Remortgages had also increased to 53,400.
Gross borrowing hit its highest level since July 2018 at £23.3bn, up from £22.8bn in the previous month and £22.9bn in February 2019.
The bank acknowledged the data was largely unaffected by the impact of Covid-19.
Data from another time
Andrew Montlake, managing director of Coreco, said: “Never before has such strong mortgage approvals data rung so hollow. It feels like it came from another time.
“Within just a few weeks the property and mortgage markets have gone from strength to abject uncertainty.
“To say the property market is in uncharted territory is an understatement.
“We’re confident things will eventually get back on track but the great unknown in the current highly fluid environment is when.
“The hope is that the mortgage market rebounds as fast as it is deteriorating once we come out the other side of Covid-19.
“For now the most important thing is that every lender supports borrowers as best it can in these most challenging times.”
