Verified with the GIS tool. 

I would try  to locate a "skiptracer" that manually searches EVERY lead you send over who wont just run it through a batch skiptracing tool and send over outdated phone numbers and data that you cant use for you business!

I have recently been told about Rebogateway. It helps provide leads and provides lists for you. Is anyone familiar with this website? Advice? Feedback? Thank you!

EDD is a great tool - check on the post office website.

Mini splits are easy to install yourself because they come precharged and require no special tools to install and they are also the most efficient heat pump from what I understand.  

+1 for Slack as a great asynchronous communication and follow up tool.

I use investorfuse for my automation and its a great tool to help me stay on top of followups, appointments, team members, virtual assistants and keep track of all the in's and out's of my wholesale business!

That said, my job and family situation limit my ability to travel to remote markets or personally manage properties, at least before I can replace my income with sufficient cash flow.What tools (books, threads, etc.) would you suggest for me to use to learn the basics of remote buy and hold?

Sure you can run comps first based on asking price to see if they are even in the ballpark but without knowing  what it needs in renovation cost you won't be able to evaluate it much further. also this gives you a negotiation tool if you know how much the rehab will cost, you can tell the seller why your offer is lower than their asking price 

I believe every sucessful investor should have a tool box full of skills, that include wholesaling, flipping, renting, buy and hold, creative finance and more!
