IE is it just effectively a secured parking lot that renters can come and go as they please with minimal oversight? 

But, could I minimize risk of renter defaulting on payments for the 2nd property by turning this property into a section 8 housing unit with guaranteed income from the gov't?

My headaches have been minimal thus far.However, most important for you is to look for a base hit, not a home run.

.**** At some point, future, I think I will want most all properties paid off so I can have great flow with minimal stress and maintenance numbers but kinda feel growth phase is still smartest as of now. 

Jumping in is very nerve racking and I'm trying everything I can to minimize my risk, but I guess I can only do some much planning before jumping right in

How do you make connections with these owners and pitch to them?

Most of my units are 1 / 1 apartments of similar configuration which has made it a lot easier to slot in new tenants with minimal gaps in the schedule.  

The idea that you can build wealth without putting any money into it is a recipe for disaster and the sales pitch of gurus trying to steal your money.

Was going for a 5% down loan but last minute had to adjust it to a 7.5% down but still a pretty minimal cash layout.

@Mary Joe in most states, a property tax reassessment chases market value.So, if you do the 2nd transfer soon after the first, the impact on property tax amount should be minimal.
