Unfortunately crashes aren't defined by assessing property price movements over generations. I'd also be surprised that the area you quoted suffered a fall in value between the start and the end of the eighties, as property prices in Ireland are generally accepted to have only fallen once, by a very small amount (1.6%?) in the last 35 years.

As in the UK, its the people that bought in the last few years, and who stretched (or lied) to afford a mortgage, that are in real danger. On a macro level its much more serious as property drove a large amount of the GDP growth in the last 5-10 years.
