My goal is to shift from buying to paying off my properties as soon as the paid off property bar hits $11k per month. 

Turn the water heater valve off and see if that stops the pressure loss. 

In the last couple months, the zoning has changed for my home, and the lot is now classified as RM1 (low-density multifamily), and I have learned that I can build 3+ units, and don't need to include any off street parking. 

An example would be that you kept your crew working rather than laying them off.

This was found off-market through a wholesaler.

Depending on the condition you'll command a better price on the MLS vs. off market.

Do you want to be hands-off?

In that case, you’re living for $2,000 a month—while building equity in the home, benefiting from potential appreciation, and taking advantage of valuable tax write-offs!

Regarding solo 401k, maybe this is slightly off topic, I use equity trust and they say you cannot have any employees other than a spouse.

If I were ever forced to take Section 8, I would start selling off anything I had in that jurisdiction.
