The study by Landbay analysed 2,000 private renters in the UK.
This comes after Landbay recently announced a £1bn funding line.
The decrease is part of a planned adjustment to 16 products, nine of which see a reduction in rates, refreshing the range for professional landlords.
Remortgage approvals were 1.4% lower and approvals for other secured borrowing were 5.3% lower than the same month a year earlier.
House price growth was strongest in the North West where prices increased by 3.4% in the year to May, up from 3.3% in the year to April.
Landbay has seen lending volumes rise by 200% over the last 12 months.
The number in May was 9.1% higher than in the same month in 2018.
Over the past three years there has been a general slowdown in UK house price growth, driven mainly by a slowdown in the south and east of England.
