Personally, I think it is better to keep your day job until real estate is providing an income stream to live off.

Frankly, using the free sources is the best thing to do for now--unless you want to spend a bunch of time and money going "all in" to focus on that one lead stream.

If all are under the same entity, you can activate the "Location" feature to keep track of the separate revenue streams, then use "Class" to track each property. 

@Kevin Hofstee I cannot qualify without my co-signer due to their inability to consider my income streams reliable (I have several different income streams as an independent contractor, and only one part time job as a "traditional" employee).

Here are some of my favorites:Pocasting and Zoom Calls: Camo Studio, Elgato Wave 3 Mic, Elgato Stream Deck, Podbean, CalDitit Thunderbolt 3 dockTask and Project Management: Things 3, Trello, ActiveCampaignAutomation: Zapier, Hazel, ActiveCampaign, TextExpander, Keyboard Maestro

Lots of vendors will up charge and rebate back to the PM as an additional profit stream.  

I recently left my W2 job to pursue a W9 income stream.

If its a property management company, you wont get much above rent payment and deposit return info, dates etc...... if its a private LL, they may spill their guts.....

I also recommend really looking for another way to add another income stream to the property (rent advertising sign space on the backs of the SS buildings, adding billboard signage facing toward the nearest highway, subleasing part of the storage unit rental office to another small business, adding a cell tower, adding metal railway containers as SS units, adding truck/trailier rentals, moving supplies retail, Amazon locker location). 

To exchange your equity for a more passive income stream, like notes?
