FWIW, I'm currently saving in a HYSA for a down payment on a rental. I don't expect we'll be seeing a 30% year like we did last year, and all metrics indicate were more likely to see a -30% year, so if you have a short term need for the money just keep it cash, IMO.
Other than that, depends on how much you want to be a homeowner
If you house hack and rent out you can significantly accelerate your path to FI, but there is a significant and real cost in the time and stress involved with landlordism
If you're a regular homeowner, expect a never-ending stream of maintenance projects that need done. Windows, water heaters, furnaces, ac, mowing the yard, fixing the lawnmower, etc ...
If that doesn't bother you, go for it, but if your lifelong rent philosophy includes not worrying about those things, tread carefully.
Personally, i could never imagine being happy as a lifelong renter, it was only ever a stopgap to purchasing something. But I can see both sides. As cchrissyy pointed out, your reasons are kinda thin. Buying just because you'll be in a city for an extra 600 days and you might get a 10% discount seems like it might be overkill.
