I am looking for some advice and recommendation on what all-in-one software I could use to track our investment properties. 

What software do you and your teams use for contacting owners, follow up, virtual assistances, etc?

When I lived in Silicon Valley at one point I was running a software start-up in my dining room.

Are there recommendations on self-manage rental property software?

Does anyone on here have any suggestions as to any bookkeeping software they use and/or if you've used QuickBooks Online for your real estate investments? 

I'm not looking for anything super fancy and I'm definitely trying to keep the cost as low as possible but I also would like to automate as much of this as possible.

Can I ask, which site or software did you use for the crime map?

Whether it's paper and filing cabinets or property management software, the sooner you have structure in your management, the easier management will be.

Ditto to what everyone else has said continue to invest and perfect your management skills and make it to were it's almost automated and then expand on both acquiring more properties and managing other people's as well.
