Fellow dual expat here, don't forget the joy of owning a US LLC in foreign countries..
MOST of the prospecting can be done remotely, if you narrow it down to a specific state or geo area. Either hire someone in the US to make calls or get ready to stay up late.. I've done both :stuck_out_tongue
The final part is visiting the park, but I can tell you that a lot of stuff doesn't pass very early DD or doesn't have the terms necessary to make a bad park doable in terms of financing. Ask me about the Park in Ohio that trucks water in every day..
Feel free to drop me a PM if you want to commiserate on the unique issues we tend to face..
