That depends on several things.
The neighborhood, the quality of the house, average prices in that area, whether you have to take a credit or whether you saved the money for it. Consider the running costs (repairs, water, power, heating)... and whether think you can sell it for the same or a similar price later if you ever want to move. For example if you found a good job elsewhere.
There is no general rule as to how much a place should cost. Except: "No more than you can afford without accumulating debts" and "As much as it is worth."
You have to be able to finance living there paying your running costs, repair costs, costs of living and the credit rates (if any) all with your normal income.
If you bought one, my fear is that you would be stuck with it. The housing market isn't expected to be that great, especially with the debt crunch the western world is having. If you're going to use it a lot, then by all means, ignore this. If you're attempting to make a profit off of it, I see it being rather risky.
You will have taxes(annually) and assessments(monthly) that you'll have to pay. Keep in mind on top of the maintenance and monthly bills that the assessments will run your costs up a significant amount. Price also depends on what neighborhood you choose to live in.
