(For those unfamiliar - $190000 New Zealand is roughly $106,000 US, and 800m2 is about 1/5 acre. I know neither Christchurch real estate nor its geology - but obviously that 1/5 acre carries a big "will it keep subsiding?" caveat.)

I can highly recommend buying property after a big earthquake - there's amazing bargains (lifetime wealth changing). I'm guessing more risky to buy after other disasters like fires or hurricanes or floods.

My land is not too bad actually (relatively) - heaps of other insured properties have similar slumping along the river or on the hills.

I've got friends with slumping issues - hidden nightmares for future buyers... In their houses you could feel the uneven floors before the earthquake and the earthquake just accelerated the problem. Pay attention when buying any house in an earthquake zone!!!

My house is actually fine -- only the ring foundation is broken and needs replacing. There are plenty of companies with the skills to do it reasonably, because it is a common issue in Christchurch e.g. a raft foundation.

The property was extremely cheap (less than half price) partly due to another issue - the driveway and front lawn gets flooded by the river occasionally (the house is high and dry).

Disclaimer: I like risk and can afford it.
