What, statistics?
Having student debt doesn't rule you out from getting a mortgage? I have student debt and have a mortgage. The debt payments are minimal when you're on a lower wage to start with (like in the region of £300 a year if you're on £30k) and it gets written off after 30 years if you don't repay it all anyway.
The impact of having a student loan on your ability to get a mortgage is outweighed by the increase in salary. If you're on £30k without a loan, you can, on average, borrow up to £135,000. If you have the current type 2 loan and say you get a £40k job, you can borrow up to £172,305. So the salary increase has a more positive effect than the student loan does a negative one. Coincidentally, £10k is how much more graduates earn a year than non-graduateshttps://www.which.co.uk/news/2018/02/tuition-fees-reform-can-student-debt-stop-you-getting-a-mortgage/https://infogram.com/student-loans-1h7v4pxk01gj2k0https://www.gov.uk/government/news/graduates-continue-to-benefit-with-higher-earnings
