You should be scouting deals daily and that will provide you the necessary feedback.  

Steven, do you know how many letters I get daily from people wanting to buy my house and other properties?

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.One thing to note when looking at the individual markets, you can make or loose money in any market.

Call volume and inquiries haven't decreased a bit and no one ever mentions the crisis.

Also, there are cases where the expenses will be higher, particularly in an RV park that has a large amenity package and daily RV traffic.  

The property manager should be refreshing those ads daily so it’s at the top when people are searching.

Grow that to 300+ properties and you've reached a point of critical mass where the level of quality if sacrificed simply because the same level of efficiency at a small scale is very difficult if not possible with increased volume. 

As a PM this makes our jobs harder a good PM has automated systems with their maintenance team, you are asking them to change their routine, and trust me most preferred vendors are a lot harder to get to a job site or to even just get a hold of than the ones we speak to on a daily basis.3.

If you would be scared to walk the streets at night and don't have the ability to do daily checks i would stay away from the historic district if you're buying a value add property.

Keep putting one foot in front of the other on a daily basis.
