Earlier this month, they sent a property inspector to one of our properties without telling us beforehand which frightened our elderly tenant when she had a stranger come to her door unexpectedly. 

We’re strangers but you’re why I am here.

I've never borrowed money from a stranger.

When you trust a stranger and that stranger betrays you, there are two lessons you can choose - never trust a stranger or expect the unexpected.

The risk would also be less than trusting it to strangers in a group(my opinion).

@Russell Brazil and Account ClosedThe reason why I thought I even have a basis for suing them is:They handed off the keys to a third party who isn't named in any of the legal bidding documents I have on hand, and that opens up the possibility that they could let even more stranger in the house that the PM nor I could account for.

@CESAR BEDOLLA --- check out Crystal Stranger.

Are your long term tenants in the other unit annoyed about the strangers there each week now? 

or even just being friendly with and chatting up random strangers on the street ....?

We don't really feel comfortable leaving them home with strangers coming in and out, pounding and drilling either.
