• Bristol is ranked top, thanks to its long-term property growth (annual average of 5.1 per cent), as well as the lowest number of long-term property vacancies (0.6 per cent), and over a quarter of residents (27 per cent) renting privately
• ranked second and third respectively, Oxford and Cambridge are once again seen as profitable investment locations after coming fourth and second in 2021
• Luton shot up seven places to enter the top 10 for the first time. This is largely thanks to average annual price growth of 5.2 per cent offering landlords an attractive long-term return on investment
• London has dropped to sixth, but remains in the top 10 due to its long-term stability and high demand from tenants
• Scottish cities Edinburgh and Glasgow benefit from a low level of property supply, which is helping to push up rents and improve short-term returns for investors
