Charles McDowell, Commercial Director, Mortgages at Aldermore, said: “These changes are good news for both landlords and limited company Buy-to-Let investors.
“Whilst there have been many changes to the Buy-to-Let market over the last 12 months, the improvement in affordability on our 5 year fixed rate products will provide much needed support to the market.
“The increasing number of renters combined with the on-going supply pressures across the private rental sector is evidence of the integral role Buy-to-Let plays within the UK’s housing market. Our new products reaffirm our commitment to supporting UK landlords.”
