I am in Livonia(just over the border from Plymouth).

You are best getting professional advice from a cross border legal and tax specialist to give you the most efficient tax structure.  

I've only been involved in one pool install, and I let my pool contractor direct me, we used tinted marcite for the body, tinted concrete instead of tile for the border, and a concrete pool deck.

1) High Property taxes and corrupt government (which leads to increasing property taxes) results in population migrations across the borders (to Indiana and to Wisconsin).

The high property taxes mean BAD news for property owners in the border cities where Illinois borders with Wisconsin and Indiana.

In north Texas, Tarrant county has far higher premiums than Denton or Dallas counties (both of which border Tarrant to the west). 

I would recommend he finds a good cross-border accountant before setting up any kind of ownership entity. 

If a community is growing and new housing developments are coming in, I'd expect the schools to get better, too.All that said, you might want to also consider Sugar Land, which borders Missouri City.  

 Property owner past and home is borded what do I do to get property?.

I live in an area in Delaware that is close to the Maryland border.
