I may have picked it up wrong, but I think i read somewhere that European and Canadian based travel providers are already reporting a 40% reduction in travel bookings to the US.

That might require a fact check, but if true, that could be quite devastating for the US tourism industry. And we're only a few months into his presidency, so one might expect that to drop further.

I also read that realtors in Florida specifically are being overwhelmed with requests for quick sales on foreigner owned properties.

It's not nothing.
