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.

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?

We are now the Central Florida Real Estate Investment Hub.....but it's all people who have met or found the meetup on BP that are involved. 

Once those funds land in your Roth IRA, you can withdraw those “contribution” funds shortly there after penalty free with no further taxes to pay.If you really want to accelerate that 10-year plan to FI, you may need to play more offense and generate higher levels of income preferably through multiple complimentary income streams.
