Whilst it is a lot of money, it's quite a bit less if you take into account inflation which will, in time, make the payments less in real terms and there is also the point that as your income increases the payments will be a smaller proportion of your outgoings.
A lot of people make a big thing about the house also going up in value over time but, IMO, that is a poor way of thinking about it as it'll only be realised when the property is sold and then the place you'll be moving to will also have been going up in value - net gain is probably sod all and may even be a small loss.

Best thing may be to really knuckle down in the savings now whilst looking for a good property in a good area OR an undervalued property in a reasonable area that you can renovate, but beware, it can be a lot of work and it's not always guaranteed to give you a huge profit. Regardless of what you do, putting the money in now can mean big savings overall.
