I am in rough agreement with some of the sentiments given by Saracen and TheAnimus on the current market. Yes, there will be an 'adjustment' to house prices as people suddenly realise that all that credit is unsustainable (unless you have been sensible- The only credit I have is a mortgage that I can relatively easily afford to pay and can soak up any changes to the interest rates if needs be) and I can see some reposessions as those people with poor credit and 100% mortgages are caught out. However, I don't see a huge crash, especially in those places where property will always maintain a certain value and kudos.
Just remember that buying now you have to bear a few things in mind:
1) Only buy what you can comfortably afford- don't stretch yourself with monthly payments
2) At present a home should not be an investment but somewhere to live- if it is an investment you are looking for live at home with the parents and buy when the market looks like it has bottomed out
3) Buy the worst flat in the best area possible- doing a place up allows you to actually add some value to it- this could be useful once the economy is in the boom part of the cycle again
4) Be prepared with a large deposit- no large deposit= higher interest rates and also the chance of no mortgage
5) Be prepared for the long haul- if you think that somewhere will only suit you for a couple of years- forget it!
As for flat/apartment living- its fine but just don't expect much storage space! We have completely run out of storage space and are consequently having to move- and no it can't be chucked or sold. If a flat is leasehold try to speak to some of the other leaseholders and see how the management agency act and charge. The management company for our flats are brilliant and have good value service charge/ground rent.
Also consider buying a newer flat rather than an old conversion- better insulation= lower heating bills and much less likely to go wrong.
All in all, flats are great first properties, just remember that there are a lot of people in close proximity! Also, you can buy now, just you have to be in it for the relative long term and make sure you are clever with your purchase.
