CML director general Paul Smee says: “These figures reveal growth in house purchase activity and in particular for first-time buyers.
“As ever, there is uncertainty and it will take more time and patience to understand how the market will evolve in the current environment – these figures predominantly cover activity in the run-up to the referendum.
“We still believe that the mortgage market is well capitalised, resilient and open for business, and will remain so for the foreseeable future.”
Kensington head of sales and distribution Steve Griffiths says: “It is good to see that lending was still increasing in the lead up to the EU referendum. However, with the result of June’s vote now decided, there remains considerable uncertainty moving forward.
“This uncertainty presents an opportunity for brokers to deliver real value to their clients by providing clarity and clear advice. This is particularly true for borrowers whose complicated incomes or working lives make them a more specialist case.”
Mortgages for Business managing director David Whittaker says: “June’s data shows that the stamp duty changes may have a softer long-term impact on the buy-to-let impact than many expected.
“For the second month there was a strong increase in lending to landlords, which saw a sharp decline following the introduction of the new Stamp Duty Land Tax at the end of March.
“Ultimately, strong market fundamentals and demand for rental accommodation will continue to provide good returns for landlords who take an intelligent approach to investment.”
