There's so many catalysts for population and job growth (Intel, Honda, Amazon, Nationwide Hospital, etc).

That's great, you have developed a system that works for you, my son-in-law in New York flips many properties nationwide, i guess I have  some credit to his success after taking my training in Baltimore - last conversation I had with him he had 150 properties under contract - he's created a machine that seems to be working.

Or, you could contact some local property management companies and see if they might be willing to give you some insight.Most traditional "property managers" would not manage properties in another state, unless they are a nationwide business.

Are there any websites where I  can search nationwide for good RE investment deals advertised by such successful flippers who are looking for private funds?

I have a few great nationwide investor friendly lenders if you need a referral. 

As for credibility, we are the 2nd largest REO real estate team in CO (volume & $), and in the top 10 for our company nationwide.

If 10% appreciation continued....it could be $560k extra equity per year.Of course, admittedly, nice appreciation on the large portfolio works both ways....you could be subject to losing 10% of the larger portfolio if there was a down turn in your market or nationwide.

Nationwide,I've seen a similar calculation in Patrick Rice's book on this subject.

I'm not sure if its nation wide or just washington, but here you are supposed to have or be a licensed contractor in order to flip a house with more than $500 in repairs.

Remember that we're a nation-wide housing shortage right now.
