Research by Lomond has found that two weeks after the Autumn Budget, fewer landlords are looking to leave the sector.
The number of tenanted properties listed for sale fell by up to 3% in some areas.
Lomond analysed properties currently for sale with tenants and noted changes since the Budget.
There were concerns about a potential rise in Capital Gains Tax (CGT), which some thought might push more landlords out of the rental market.
However, these concerns eased when it was confirmed that increases in CGT would not apply to residential property.
While second homebuyers and buy-to-let investors faced a 2% increase in Stamp Duty costs, the overall sentiment among landlords appears to have improved.
The figures showed a slight decline of 0.6% in the number of tenanted properties for sale across England, with a sharper drop of 3% in the East of England.
The South West saw a decrease of 2.5%, while the North East recorded a decline of 1.9%. Four additional regions also experienced reductions in tenanted for sale stock.
The East Midlands saw a 1.4% increase, and the West Midlands showed a rise of 0.8%.
Ed Phillips, CEO of Lomond, said: “It’s becoming fairly apparent that the exodus of buy-to-let landlords has been somewhat exaggerated and the vast majority continue to see the rental sector as a secure and consistent avenue of investment, despite the government’s best efforts to dent profitability.
“The good news is that having escaped a capital gains tax increase, we simply haven’t seen a rush for the door following the Autumn Budget.
“We expect the buy-to-let landscape will continue to remain positive now that the budget dust has settled.”
