[Landlord, U.S.-GA] Is anyone else pausing construction projects?

A couple of years ago I had the chance to buy a string of 10 adjacent lots in a decent, in town, pre-war neighborhood zoned to allow multifamily. I had planned on starting construction this month. But since our illustrious leader just kinda sorta maybe announced a 250 percent tariff on Canadian lumber and 25 percent on other projects. Since 30 percent of our construction lumber comes from Canada and 70 percent of the Gypsum used in drywall also comes from Canada, as does a bunch of our construction materials. Then there's the potential labor disruption that will come if the mass deportations ever start.

I have until next week to cancel my contractors with a minimal kill fee. I hate to do it because I've been working on this for years -- and I've been building a relationship with this contractor for years and canceling would damage that -- but given the unpredictable vacillation of our current political regime I'm almost certain it's smarter to wait anywhere between two to four years before starting construction.

Am I being too alarmist here? I was never a fan of the current President, and given his recent action I'm concerned about the economy. But, how much of this is just my own political prejudice? Arguably it looks like Trump has no moral center, no economic understanding , by his own admission isn't "even looking at the stock market," and can't hold a thought in his head for more than a day. But, ya'know I'm not the most objective person here.
