A highly skilled Guatemalan (my preference) or Mexican laborer will cost you $150 per day.  

Regarding your situation, the appreciation strategy for real estate investment is compelling, especially in a high-demand market like Vancouver.

I considered SFH where I'd rent out all the rooms and keep one to myself, but this seems risky since I'll realistically be away for months at a time and couldn't manage the unit/other tenants.Then I came across some listings that appear to be hotel rooms for sale, with basically the facilities I need (a bed, toilet, kitchen), a price point I can handle (270-500k$, I'd do 20% down), and fairly high HOAs (~1500$/m?).

I just think the rents are low enough to get a whole apartment outside the in demand areas that you'd have a tough time with getting quality tenants wanting to rent a room over just renting a studio or 1BR apartment.

He also gets to enjoy California's low property taxes and high appreciation which has worked well for him.
