Interesting question, and one no doubt in the minds of millions throughout Trump's Presidency.
Let's take this top scale and then scale it down a bit. Globally, if you look at the Housing Bubble in 2007, this shook the world. Especially for us Westerners. I'd hope that humanity has learnt it's lesson following this but looking at the course of history, this is unlikely.
As such, Global issues create volatility, volatility creates unease and this means people move money. Where money is moved, some markets receive the money, some lose it. But again over history, it always seems to find it's way back!
Now on a smaller scale, the UK for example, the property market can be seen as simple (although let's face it, it's not). Supply vs Demand. If there are 100,000 properties for sale, and 200,000 households are looking to buy, they enter into a bidding war. Highest bidder tends to win. If there are 100,000 properties for sale and only 10,000 people want to buy, those motivated sellers (i.e. those who can't comfortably hold onto their homes) will have to bend to the buyers offers, making it a 'every man for himself' situation. i.e., take what you can and run.
So to bring it back full circle and in my opinion, yes the huge cogs that shape a countries economy will change, which will in turn have an effect on the UK property market. But it's easier and again in my opinion, just as effective, to base predictions on what's happening closer to home with supply and demand.
I'd be interested to hear what you think.
