Master in real estate finance - what are my chances??

With a 2.2, you won't get into lse or Cambridge. That much is for certain. Even with a low 2.1, it might be tough to gain entry.

You really cannot get a 2:2. You need to aim for a 1st really. You can get into cass with just a 2:1 but ucl/lse/cambridge will like to see a high 2:1/1st.

For the likes of Oxbridge and lse, they receive tons of applicants who get 1st or high 1st. Even though they mention that the minimum requirement is a 2.1, that's all that it is. The minimum. You'll be fighting with other candidates who have a first.

I myself will be applying to the lse for September 17 intake. Although I'll be applying to a different course, I'm not entirely confident I'll get in, even though I've maintained a high first average throughout my time here in my undergraduate. That's simply how competitive the spots are in these schools.

The only way I see you gaining entry is if you have something that sets you apart from other candidates that they're willing to 'overlook' tour relatively poor results.

I can't comment about cass or ucl.

You should consider applying to 'lower tier' schools as well.
