I don't really want to invest in a D-class area.Tangentially, what are some of your "it's time to sell this property" red lines when it comes to the changing economic conditions of an area?

DOM nationwide isn't really terribly useful; in extreme situations we will already know the national economic situation.

The state's economic dynamism, natural beauty, cultural attractions, and educational institutions continue to draw people and investment.

KNOWING real estate (or delivering babies) is a requirement for an expert. 

I am definitely not an expert on international investing as a whole though so I agree that it is a great idea to get in touch with someone who has more experience with it!
