Some very big assumptions being made about the op's ability to save built on not a lot of knowledge of the person in question (nothing new there from what I've read in the past).
How do you know their personal circumstances? There could be divorce or some kind of colamity in the past that has sucked up all cash. Depressing as it it for the rest of us, but there are some professions (medics for example) that can virtually start their working life in the upper tax band but with some serious debts to pay off. I could well imagine a couple of doctors only a year or two into their working life "only" having 10K saved.
Then of course there is the fact that rental rates are not a great deal different from mortgages which makes saving harder than it seems even for those lucky enough to earn that sort of cash. As one of the last of the generation that got through education with not a lot of debt, it must be pretty sucky at the moment being fairly newly graduated - you have studied hard all you life getting good grades then done "the right thing" and gone to uni only to be saddled with £20K of debt and even if you do get (and keep) a good job, you have years of paying back the debt before starting to save way more (as a proportion of income) than my generation had to before having the abilty to buy a house.
Good luck with it - if you can get a descent offer, now would seem like a good time to get into the housing game with the rest of us having just taken a 20% hit. You might not have much to offer interms of savings at the moment, but as they say, if you don't ask, you don't get!
