Looking at their forums, their moderators are against any kind of growth or adaptation of new technologies. 

Those losses can be substantial, by the way within an HVAC system-Again I doubt these technologies would hold up under scrutiny within a court of law because all it takes is one person with even a basic grasp of principles of engineering and you’d find an easy 10+% delta in these systems’ measuring abilities.

I have a background in technology and real estate (I was a previous VC-backed technology company founder), so I am very tech-friendly, and I like to adopt solutions that streamline workflow/enable best practices. 

If you do not like bookkeeping/accounting/technology, hire a bookkeeper specializing in real estate investors.

These types of places typically don't use alot of technology or have great systems, making it easy from a management perspective to turn things around. 

Technology is a good partner the more you know on your own.You should make a list of areas you might be interested in first - maybe you lived there or have friends there, you always wanted to go there - and then compare that list to some best areas list, do some of your own research, and then use a major data tool to look.

I will add, with technology, it is quite easy for overseas investors to invest practically anywhere in the US.

Technology has been been a huge factor for both. 

I wouldn’t invest too much in old technology right before demand creates improvements. 

I'm an IT Consulting guy by day & RE investor by night so getting into the details of all of the technology offerings, how they integrate, which capabilities overlap/don't, where integrated value sits, etc. exposes my nerdiness/love for this kind of stuff.
