Auckland Buyers Storm Wellington?

In the last week I have had three offers from Auckland investors: one has bought this beauty in Thorndon from me. Way over its silly RV of $1,050,000. Yielding over 6%, on a lovely 550 m2 section in a great street in Thorndon ( Burnell Avenue). Bought without physical inspection though the buyer knew the property and carried out full diligence. The other two offers were made sight unseen also. I’ve rarely  had even one offer like that in 26 years real estate. A trend or an anomaly?
