This is interesting and I look forward to the feedback.But, I don't know if I want extra buoyancy in a hot tub?

CA doesn't have an extra $30b/$40b laying around to do that, not to mention the additional billion to actually do the project to be build ready. 

You are not going to qualify for active and will not get any extra depreciation.

-A water heater issue resulted in repeated mismanagement—confusing unit assignments—leading to extra costs to fix the same issue 3 times and on each occasion "more fixes" needed to the water heaters that I plumber said was needed.

Politely and clearly, make it extra clear that all information will be verified including income prior to the signing of any lease.  

Because the extra family members weren't on the original eviction, I had to wait another 3 months to get them out. 6 months altogether. 

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

I'm also working on a Google Data Analyst certification to bring in some extra income while I'm home with our 19-month-old daughter.I'm still pretty new to this, though, and I'm not sure where to start or if I'm on the right track.

If your average heating bill is $150, you may not collect enough in the winter months when the bill reaches $225 but you'll collect extra in the summer when it drops to $65.

Something like a house hack, rent out extra bedrooms in your unit, rent by the room, mid term, short term rent the owner occupied unit on busy weekends (and go stay with friends/family)...get really scrappy.
