If this is a “large” complex, you contact Tesla and they will help you plan, install, and setup the whole thing.

I left numerous contact me letters to speak to the owner to discuss options and potentially cash for keys.

Your scattered approach is going nowhere fast (analysis paralysis) and is highly likely to result in someone taking advantage of you:(Recommend:1) Figuring out what investment approach suits your skills & risk tolerance2) Determining where in the US to apply your chosen approach3) Learning everything you can about that market4) Networking & building contacts & team in the market5) Doing a "test" investment in that market to make sure your expectations are met6) Investing more if your expectations are met.-- If not, go back to step #1 as you many have chosen the wrong approach!

I have a friend who is very happy with Anderson so I'll be contacting them as well, although apparently they are more expensive.

Especially with contractors... my construction consulting team is nationwide so I have a lot of contacts that I trust. 

Contact a few syndicators as an investor, and ask all question you have.  

Last-minute trips are rare but can be avoided with a trusted local contact handling issues promptly.

I also tried contacting support twice, and both times they only provide a link to the book in the store without addressing any portion of the inquiry. 

Here I have contact info, lease info, AC filter, trash day etc plus all the income and expenses.Then I have a Master tab that has all properties, so I have the big picture of gross rents received.

Account Closed, I have had my 4 duplexes in Houston managed since 2008 by ELDA Management Services http://houstonpropertymanagement.com/Don't hesitate to use my name when contacting Rina or Elias Camhi.Like you I live the Bay Area (Pleasanton).Hope this helps,Fred
