Can you make money by predicting the average house price in the UK?

It feels like this should be possible, much like how you are rewarded for predicting the value of stocks.

I’d like to find the best way to do this that’s as accessible as buying & shorting stocks (buying & selling entire properties regularly being beyond most of the public, including me!)

I’ve found two REIT ETFs. UKRE’s performance looks sort of anti-correlated with UK house prices, meaning that this is my best option so far. Is there a better one?
