please dont turn it into an "open space" modern home! 

This book really opened my eyes to the possibilities of out-of-state investing and how to manage using technology - like you, I also live in an HCOL area but invest out-of-state.Best of luck and good choice choosing to learn more about RE!

It makes sense that they could apply them.HOWEVER . . . our modern world doesn't know the meaning of the word "justice" any more. 

The things to look for are: * Population growth* Job growth* Incomes* Modern/diverse economies* Capital investment and business expansion * Low property taxes* Favorable landlord/tenant regulations

Any add-on technologies I should leverage to manage the property, cleaning service, or etc?

Real estate isn’t a technology that becomes obsolete.

Also, you might live in an area with more modern house lots than I do, so you're less likely to have some of the issues I listed above. 

However, it sounds like it's fully functional and just missing some modern safety features.

I’ve been reading “Landlording on AutoPilot”and given that I  am an injured Vet(wheelchair bound) , learning I can handle everything pertaining to the business with my technology is amazing….

I did all of this quickly as any young kid who is technologically able could, and the company controller who I was working under was impressed by my speed of completion.
