I live on the border.  

Yes, they do - but that knowledge doesn't exist only within the state's borders.  

@Scott E.I live in South Texas right by the border and many towns in my region are growing and rents are increasing with every year that passes by.

This is a particularly strong issue in border areas right near a state line.

The problem is that I found out from the plat map that on the .27 acre lot, there is a drive way encroach on one side and there is a corner of a townhome complex encroaching on the other border. 

As you pointed out with Castle Point...it is not a good area at all, and it borders Bissel Hills, which is a much more investment-friendly area. 

It enables your company to legally pursue growth opportunities across state borders without having to incorporate a new business entity.

I've dealt with TD also but found RBC to be much easier to work with for cross-border purposes. 

Your friend should also check with an accountant or a cross border specialist on the best way to approach this, if they are not already set up to do business in the US.  

If you want more control of your rentals, why don't you look just over the border in NW Indiana.
