Investec Specialist Private Bank has seen a 46% increase in the number of mortgage deals it has completed between June and August compared to the first quarter of the year.

At the same time, the value of these mortgage loans has increased by 43%, compared to a nationwide increase of 29% over the same period.

Investec argues that increased demand for its high-end mortgages – £1 million and over – is due to inflexible lending criteria used by other lenders and its own personalised service, which is based on the income and wealth of the individual client, but within tight affordability parameters.

Wayne Preston from Investec Specialist Private Bank said: “This year we’ve seen an increase in the number of people coming to us for residential mortgages because of our highly personalised and more flexible approach. We concentrate on the intricacies of a client’s finances in order to better understand their ‘true’ wealth as opposed to taking the rigid stance adopted by many other lenders who remain focused on the property asset rather than the individual.
