I agree with her on an unborn child is still a life, an American Citizen if they are in the United States.

Is Canada becoming a better place to invest in buy-and-hold real estate for US citizens/ residents?

We are one of just a couple of countries in the world that taxes citizens and residents based on worldwide income and nobody wants to deal with that stuff.

My husband is a foreign citizen and we are in the process of petitioning for him to receive a work Visa so he can live and work here.

Most transportation studies I have read indicate your average U.S.A. citizen will walk no more than 5-minutes (400 metres, ~1300 feet) to a service or work (Canadians only average 100 metres more) .. this would put 1-mile beyond the acceptable walking distance for most.Since you do not disclose which expenses you have incorporated into your analysis, we shall assume you've  not missed any.    

Puerto Ricans can travel freely to the U.S. mainland without a passport because they are US citizens.

So if an applicant has had a lot of problems as a renter or being a law abiding citizen, and you rent to them, you get a front row seat to some human drama and some headaches for sure.

It's a giant albatross that limits (affordable, especially) housing development.As a citizen, however, it's not so clear.In CA, we have a regulation called CEQA - it gets in the way of any development activity and basically says (my words): "If you're going to make the environment worse for anyone by building this, you better figure out how not to ... or pay to mitigate it some way." 

Also, citizens get to attend town hall to speak for or against your project in an attempt to influence commissioner's vote.Back to zoning - does the zoning allow for clustering, if so, how many acres are required to cluster?
