There is a tool on the Nationwide website and you put in your year and quarter of purchase your location and also the price you paid, you can then if you are bored enough track your house value quarter by quarter.
We bought in 2000 for £250,000, one wet cold Sunday afternoon in about 2015 I tracked every single quarter since then. ( DS was monopolising the TV, he was too young for a tv in his room and I was bored)
In short, in the quarter following 2008 the market stagnated for a whole three months, ever since it has increased quarter on quarter, some quarters slower than others but still climbed.
Our house has increased in value by 215% in 22 years so I am unsure of where your DH gets his confidence from.
I would love the market to stagnate, then DS might be able to buy around here, as it is, he lives in a three bedroom detached house bought for £250,000 and now he would love to be able to afford a one bedroom maisonette for the same price.
Your gleefulness is distasteful TBQH
