While there is often a delay from sale to distributing to investors to cover various bills that were incurred during ownership but received post close, typically these are cleared up within a month, maybe two.The bigger issue is not "doing what you say you will do".  

Tesla will help you set up and do the billing.

@Jose QuinonesHow much is the water bill?

Depending on the amenities offered, and many HOAs in my market will also pay water bill, possible cable/internet, pools, hot tub.

No Bill Pay for the Cash Management accounts...
