Hi @Kent Nielson, I think most folks from Portland do tend to stay in Portland since there is so much more to do there then across the river. I feel that it is more likely that you would have people from Vancouver crossing the river to go to Portland versus the other way around. There is one exception I have found with real estate investors. I am finding Portland follks are investing into buy and holds up in Clark County. Flipping is not as much fun in Vancouver due to the excise tax when selling.
All in all I think it makes sense to continue networking with people in Portland because as time goes on more and more people will be moving across the river when their financial and family situation aligns with moving north. It is hard to deny the appeal of 0% income tax and the overall quality of schools and infrastructure that is being put in place in Southwest Washington. If you have a family, make a good income, and have the ability to work out of a home office it is a compelling move. Also, if you are retired it makes a lot of sense as well.
It also depends on who you are trying to network with. Is it future clients, vendors, or partners?
