First of all, you picked a great PM with WHM - Ed has been running a very good business for a long time! 

Pick one forum where your question makes the most sense.

Your best bet is to find someone doing the work in your area and picking his/her brain. 

I live in MN and fully trusted my original realtor when he said it was a great area and I bought right after the hurricane so every corner had garbage and debris waiting for city pick up, now a year removed, it's much clearer that my neighbors are not interested in cleaning up their properties as other areas are now. 

I've heard of mentees who started cleaning up construction areas on a flip at the end of each work day or picking up supplies at Home Depot and delivering them to the job site.

That leaves a grey area in between, what if you are not swinging a hammer, but just picking up trash in the yard as you walk by?

Last time I was there, the indigineous people would pick the beans. $5 for a 5 gallon bucket full.

a lot of folks in California pick out a property they don't see in person, trust people they don't know to manage it, and then it goes south. 

I picked up another duplex for my personal portfolio that will bring me to 14 doors.

I hope they all turn out great, and the best case scenario is you struggle to pick which one to buy with next because they are all so great!
