I have been basing my business of of my sphere of influence no results so far.

I'm looking for not so obvious tips, sort of like:how a certain neighborhood would have provided major tax breaks but you bought property 2 houses away outside its dividing linefinding out that STRs would have yielded better income where you investedbuying a certain design of a house (whether that's describing its foundation, exterior, interior, etc.) was a bad ideapolitics and local government influenced your returnsand so forth.

In the end, if your deal is profitable with conservative assumptions, then you should be insulated from any market influences. 

This combined with the risk factors of losing potential rent on something that I would have to come out of pocket to pay the mortgage on and other factors would influence my overall decision but ultimately cash flow would determine my decision.

I agree about the influence some bloggers have.  

The other thing is TRUMP because his decisions influence what people do there is no exact answer it goes by your market and what you can obtain from it.

Make sure you make them feel responsible for part of the property even though it's yours if you make them feel good and responsible they (tenants) tend take pride in the property and the next time it may influence them to act on their own and fix the problem on their own.

Expand your sphere of influence, build the team to make the deal and set up the next one.

Don't try to stretch the number because of outside influence or emotion.

I think my blending of loan products is also influenced by how much financing I'm willing to do across my whole portfolio.
