On Thursday, July 12 my contractor stopped communicating with me. 

Also, clear communication with your parents about goals, risks, and expectations will also help avoid tension.

Is communication prompt and reliable, K1 delivered on-time?

Our architect has been slow to communicate and get the work done.

It's not just about slapping a price tag on stuff; it's about effective communication and making sure you get those green bills in your hands.

(many contractors are going to bite off more than they can chew and communication will be key). 

We communicate almost everyday.

That can make it easier to communicate the opportunity effectivelyTo expand efficiently, consider targeting local real estate meetups or investment groups San Diego has a strong investor community.

I would work on my communication of my processes including letting them know asap of their schedule with me. 

Assuming you already paid for the first occurrence, if it happens again and the plumber doesn't find anything wrong then, yes, the tenant should be responsible for the invoice.Your PM should be setting those expectations when they communicate with your tenant."
