A survey conducted by Bradford and Bingley of almost 5,000 buy-to-let landlords across the UK has revealed that the vast majority of investors remain confident over the future of their investment portfolios.

The study revealed that 94% of landlords were expecting rents to either increase or stay the same over the next six months, which is a rise of 7% on figures released 12 months ago.

Investors with buy-to-let mortgages largely use their ventures as a way of recouping additional income, with just one in ten employed as a full-time professional landlord.

Andy Wiggans, director of mortgages at Bradford and Bingley, said: “Buy-to-let remains a popular market that attracts a wide spectrum of people from all walks of life looking for long-term capital growth or a means of supplementing their pension.”
