It depends on what your priorities are. On a purely economic basis, now would be an awful time to buy in my opinion. Consider that generally (with a few exceptions) prices have been falling, even with the assistance of countless Government props; but these are temporary and are starting to be withdrawn.
For example, the first-time buyer's stamp duty holiday will end in March - think how many FTBs will have brought forward their purchase and thus how few there will be after this ends (to give you an idea, transaction numbers fell by over half after the first stamp duty holiday ended
).
We also have Local Housing Allowance being reduced, which will reduce rental yields and disincentive Buy-To-Let. And on top of this, we have rising unemployment, inflation and benefit cuts eroding incomes. And to top it all, we have the possibility of another severe credit crunch (remember prices dropped by around 20% in 2008/09 during the first).
Of course people will always say it doesn't matter as long as you don't intend on selling for a while. True, but what happens when you come to remortgage and don't have sufficient equity for a decent rate, or you have to relocate for work or other reasons? Also, I'm sure that wouldn't be much consolation to those in Ireland knowing they could have bought an identical home for half the price if they hadn't bought at the peak of an obvious bubble.
Like I say, these are the economic arguments (and I come at this primarily from an investment perspective) but of course buying a home is about more than that. Just as long as you don't view it as a particularly savvy investment - those days are long gone as far as I'm concerned.
