Good luck RR and missus!!
I started a new job last Monday, and one of my colleagues was telling me similar stories about property sales at the moment.. their original house is now red zoned, so they (along with many others in that position) started seriously house-hunting as soon as the announcement was made.
In one case they and 2 other couples decided to put in full asking price offers within an hour of viewing a house - the owner, presumably very pleased, gave them all his preferred completion date and said that if they were willing to agree to that date could they get back to him by COB with their very best offer.
I am so very VERY glad that we got sorted before the quakes.. it was so close that sometimes I boggle rather than grinning madly.
