Not sure which markets you're considering, but if you set your sights on the coast I can help with local lenders, attorneys, tax pros, etc. 

I've never seen that kind of layout here is east coast.

Here in South Florida, on the Treasure Coast, we have a Real Estate Investor Association and the networking is great.

Selling now could free up your equity, giving you the option to diversify into other investments or markets that align better with your new life on the East Coast.

don't know if this is still true, but at one time foreigners could not outright purchase property in Mexico within 100 miles of the coast. 

If I'm not mistaken, you'll need to setup your RRSP with Trust holding company such as Olympia Trust or Canadian Western Trust, etc. 

I suppose this is routine for East Coast lenders.

I live in California (Central Coast) and have built a 12-door portfolio in Detroit, which has been a great market for both cash flow and long-term potential.Detroit still offers properties well below the $150k mark, with strong rent-to-price ratios and a market that’s seeing growth in key areas.

I would highly recommend talking to Jeff Weller at Coast 2 Coast and Fernando Corona both are also PadSplit hosts but we're some of the first expert lenders .

Out of your list, I suggest the Northern and Western cities you listed (Conroe, Montgomery, and Katy).
