Great, there is a lot of guides and resources on managing properties here, and analyzing deals.

We use Avail.co to manage our rentals' leases, rent collection and checks.

Not fully rented, but in a highly desirable location? 

What I'm hoping to find: I'm hoping to make connections, for mutual benefit; this could be investor friendly agents who have experience with identifying promising house hacks, investors who are looking for an additional financial partner, investors who are looking for a partner to help manage the load of projects (I am naturally drawn to planning and execution), and more broadly anyone who is willing to share experience and create new connections!

.: I’m currently renovating a rental property and exploring ways to manage costs without compromising on quality.

I'm looking for a spreadsheet or tool to use an example to log and track hours spent on real estate Managment.

Property managers and agents can be really helpful as well as they’ll give you insight into the market and could have some opportunities for you down the road.In the meantime, try researching the areas you're interested in.

We live in Northern Florida and manage our 10 long term rentals and do flips in northern Florida and we decided not to go that route with this south Florida home after we started digging into it.  

Quote from @Jacklyn Robins: You've "never" had this issue, but you've only managed a few properties for five years.

@Brice Alef-Torrisi putting each property in its own LLC is usually overkill.Getting a bank account for each LLC is typically something you need to do to avoid "piercing of the LLC corporate veil" (actually depends on tax selection you made for LLC), but is also overkill.You haven't indicated how you are holding the deed for the latest property.If in your name or same LLC, you don't need a separate bank account.If in separate LLC, you can create a Master LLC, have each property LLC hire the Master LLC to manage their affairs, and just get a bank account for Master LLC.This is an opinion, not advice, so lookup CPA Frank Alcini in Troy for expert advice.
