If you suspect someone is a trafficking victim, call The National Human Trafficking 24-hour Hotline at 1(888) 373-7888 to access Central Ohio's local response network.Danae King

But make sure to do more research, connect with local agents that know the market, connect with investors who own rental properties in that market, and then decide if that's going to be your main stomping ground. 

What are the best practices in this situation, especially considering any local laws and regulations that might apply?

If it's a commercial lender or portfolio lender or small local bank they may not care where it comes from.  

Also considering Airbnb type property and outside of local area if the numbers are right..

If you are laser focused on specific properties, door knock the owners if they are local.

Additionally, your local FB groups and REIA's will have them.

This could be contingent on the market you are in so you may want to source locals in your area and how they handle.  

Some clients of mine have used a local company called REZIO who will do the drawings and facilitate the permitting for you.

I would recommend networking with some local investors in Texas who could give you unbiased feedback (not someone trying to sell you anything) and 3 to 5 property managers.
