I’m looking for suggestions for resources on researching and evaluating new markets. What are the things I should be looking for and/or avoiding etc.....
There are a lot of posts on this subject, but I'll take a crack at a high level:
Macro environment: rule of law, diversity of regional economy, positioning of regional economy, etc
Supply and demand equation for properties, both on the sale transaction side, and on the rent side.
Specifically, you're looking for pricing of both.
The higher the rent/price ratio, the better as a landlord.
