My dad used to manage other people's properties but eventually quit because the money wasn't worth it and he always ended up prioritizing their properties so as not to get any hassle from them.Another way to approach this might be to go all in on one project yourself and see how far that money gets you. 

They eventually declared bankruptcy.

This leads to state funded insurance which will be very costly because only those at highest risk will participate in it and if the losses continue, they eventually will need to get the money from someone (rest of people in california?) 

Value and rents should eventually increase to turn cashflow positive and build your wealth.You're next learning experience will be, now that you are out of day-to-day management, how will you be able to handle the inevitable expense challenges?

After ignoring them they eventually went away. 

It was a long and expensive journey, but eventually, we won the court battle and were able to move them out.After they were gone, we cleaned up the house and decided to list it as-is instead of flipping it.

As someone who eventually wants to buy, I don't see that making much sense.

I'd guess half of this final third eventually sold, even if several years later. 

I have a commitment to invest in rental properties, meet professionals  & eventually meet potential business partners!

I made an effort to connect with everyone until I eventually connected with the top investor/broker.
