While demand for housing in the private rental sector continues to hold strong in the current climate, investors still have to take into account the varying need for properties in different locations if they are to maximise profits and attract prospective tenants.

With this in mind, one expert believes that landlords should look for cities that have two or more universities when considering investing in student accommodation, as the increased number of prospective tenants that will be looking for rental housing nearby will enhance opportunities for profit.

Marcus Roberts, director of student investment and development at Savills, said: "You would typically be looking at those cities that have got twin universities first and foremost, so that you get a double hit of full-time students."

Despite students being well-renowned for their laziness when it comes to levels of cleanliness and general maintenance, providing housing to those who are in higher education is a profitable venture for investors, and they are able to protect their assets with efficient landlord insurance policies.

Indeed, this is just one of the many factors to take into account when investing in the overall buy-to-let sector, as protecting holdings is vital to ensuring their profitability.

When getting involved in the lettings game in general, if landlords get it right and find somewhere that generates significant interest in the tenancy then their chances for success are far higher than if they opt for property in areas that are isolated from shops, transport links and schools.

The same could be said to apply to investment in student accommodation - a sector that is widely perceived as a safe bet when it comes to investing and letting - as young people are going to be looking for housing in locations that are close to campus rather than those that require extensive travelling.

As such, opting for cities that have twin universities could be an ideal means to ensure tenancies will be quickly filled by high numbers of students requiring housing.
