With all the measures they have, it's never been an issue to my knowledge and the neighbors would let me know in no uncertain terms, as they had a poorly managed STR in the neighborhood previously. 

The purchase decision might make itself clearer once you are here, have boots on the ground and are not pressured to make a decision from long distance.

Personally, I've felt the investment has been poorly run in almost every possible way.

I will join some local real estate groups (act poor) and see what I learn. 

Like @Collin Hays said, it is being driven more by neighbors tired of poor STR owners not keeping things sorted.We only look for places in vacation areas with a long history of owner driven STRs vs big cities and the like.

That makes me feel suspicious and my decision is to go to another one. 

I'm curious, at what point does this reflect poorly on PM and suggest I should get antoher PM?

My previous tenant left the yard in a poor condition before moving out.

Your Broker has the ultimate decision on whether or not you can do it. 

Incredibly poor business deal.
