Nice investment there 300 --> 2520000, a nice 8400X move in 70 years. Actually its only a 13.77% compounded annually but still pretty good.It is believed the property last sold as an empty block for approximately £300 in the mid-1950s, according to the owner’s children.
Looks like Australia is like California here in the US. I'm sure the UK & NZ are in the same boat.
Here in the SF bay area you see the same craziness. I believe a 2 bedroom house in Palo Alto that hadn't been updated in like 30+ years sold for $4 million. The new owners tore it down and created a luxury estate from it. It was land they were buying.
