I’m no defender of Mexico, but it has been a good investment for alot of people over the last 30 years. It all comes down to risk reward. I’ll say this in defense of Mexico. If its so unstable at this point, why can you get American title insurance? I know you can as my father lives there.
I haven’t been to Manzanillo since my fathers boat broke down in the bay next to Las Hadas almost ten years ago. It was nice and sleepier than Mazatlan or PV. Its also a heavy port so there is industry other than tourism.
As to Canadians, there are alot of them in PV and Manzanillo, as well as Mazatlan. The pacific coast of Mexico seems to be a favored travel destination. Most places you go put out Canadian flags whenever they put out an American one (PV at least.)
