I'm ready to buy my 1st rental property and have identified a foreclosure that I would like to buy.

Identify some areas you would like to invest in and get to know them well so when you see a property come available you'll know if it is a good deal or not. 

But it you cannot identify a specific cause for a problem at that location then its likely you're just looking at the first of multiple problems.The sellers may balk, but your agent should remind their agent now that they're aware of a problem they need to disclose it to future buyers. 

Hello,I've done searches on specific areas that have been identified for revitalization in Baltimore, but I keep coming up short.

How does one go about identifying reliable providers remotely, out of state?

Do you have them all laid out and just need someone to review and identify the holes?

But how do I identify value- add potential, and how do I estimate the "ARV" after improvements are made?

The good news is that most of these can be identified with a home inspection. 

Make few adjustments and use the average.What your initially doing is identifying possible properties to evaluate in more detail.
