I am a big fan of the "x-in-ounces-of-gold" calculation to get a real sense of "prices".
Last year, a house in my neighbourhood went on the market for £280K in August and I think sold for around £290k in November, when gold was around £490/oz.
Using the November figures, factoring in a 30% drop from the peak (I will use £290k here), and the subsequent rise in the ££ price of gold, the cost of the house has dropped from 592 to 335 ounces of gold.
I find that amazing.
