@Kash Tacke I'm a big fan of ADU's in general especially here in the mid west, yes you could potentially be on the front of the wave, but housing density is the solution to the affordability issue, anytime you are investing with affordability in mind is a great strategy to me, and sound like there are some incentives or at least supporting winds form the local city, that in itself seems like it would be worth at least approaching an architect or contractor to bid up some plans or concepts to take tot he city.  

I’ve been offering a $100 referral fee for existing tenants who refer a new tenant to any of my properties.

There's a few different ways to focus on a lower rate such as with house hacking and making the investment your primary residence, requesting a significant closing credit from the sellers for standard rate buy-downs (which I've had great success with recently), or utilizing lenders who offer short term rate lowering solutions such as 2-1 rate buy downs (again, ideally paid for by the sellers).

You say "skip tracing is outdated" but only make a vague reference to "creating your own leads".

Private lenders or even creating a small syndicate with a group of investors might also be worth exploring, especially since you can point to your uncle’s track record and your own experience managing rentals as a selling point.If timing is tight, you could look into a bridge loan to secure the property while figuring out a more permanent solution.

We give an A-Z Solution.

We are in a similar boat, however I have not yet found a solution for less than $5K even for above the ground.

You can also leave out some bulk hotel toothbrush/toothpastes, make up removers, earplugs, sleeping masks, etc. if you really want to step up a "In Case You Forgot" basket.You can keep a closet with extra of things that has a lock on it and if someone is irrate because they don't have enough pods, you can at least have a back up solution for them if you choose too. 

I will use that number as a reference:2.
