Is BRRRR method feasible (or mathematically worth doing) in Vancouver region?

Afterwards, plan would be to "hopefully" do some long distance investing in the Hudson Valley/Catskills or PA region and farther down the road.

I now have been able to meet people working and learn the various regions.

Personally, you should speak to a regional and mention that you will leave if this happens again as it is not the first time.

Many times these events also have opportunities to donate/support the charity in exchange for some promotional.3) Host your own local or regional meetup for accredited investors-only.

I am from upstate NY (Capital Region), and I have zero experience owning real estate. 

First step is to check zoning and discuss options and uses with the city.As far as development goes You most likely will not be able to attract a national or regional tenant with such a small demographic. 

Some things I have learned about Maine that need to be considered though:Taxes are relatively high compared to some other regions (all of New England/northeast are generally high property tax states)Heating and utilities are expensive here and often cut into landlord's profits as some of these are more difficult to pass on to the tenants than in other regionsThe housing stock is generally really really old (early - 1900s) and that comes with a lot more maintenance and CapEx than newer homes.

You can  have national. regional, and mom and pop tenants.

That will hopefully help give you some direction as to what region of the state and what types of properties you're drawn towards.
