Leeds has the greatest number of available student properties to let at 6,033, equating to over 552sq km according to UniHomes.
London followed, with a total of 4,113 student rentals available.
Meanwhile in Bradford, there are only 70 student properties available.
Southampton has the highest density of student rental availability in the UK with a total of 1,641 properties available, which is over 50 sq km.
This was followed by Portsmouth with 1,286 available properties over 40 sq km.
UniHomes analysed market listings for student accommodation in 23 major cities across the nation and found that on average, there are 1,669 student properties available to rent per city.
Phil Greaves, co-founder of UniHomes, said: “Heading off to university means a long checklist of things to get sorted and while freshers will often organise accommodation via their university, those returning for a second or third year will need to add a place to live to their to-do list.
“Although September seems a long way off, finding the right property can be a lengthy process and our research shows that it could be far trickier in some university cities compared to others.
“The level of student lets available can differ drastically from one location to the next so depending on where you plan to study, you might need to start looking sooner rather than later.
“Even in areas with the highest levels of rental stock, leaving it until the last minute can mean settling for a property you’re not quite happy with, whether it be due to size, location or otherwise.
“Our research also demonstrates some great opportunities for landlords in cities with the lowest level of student rental stock.
“Students provide a consistent stream of rental income and in areas such as Bradford, there is a real gap in the market for student rental properties.”
