@Andrew Johnson  they self manage.. its a JOB big time and all consuming.. you cannot make a go of it out sourcing management and repairs you will bleed to death. 

I am just happy that the bleeding stopped.

With it being so close to Dignowity and down town the values will eventually cap and start to bleed over.

@Thomas S. Well

I am more interested in long term wealth building but also looking for some cash flow to ensure that I won't be bleeding money every single month going forward.Has anyone successfully hacked a 4plex in San Francisco or in bay area in recent past? 

I bought in Somerville in 2009, Medford in 2014, and am now seeing that insane growth trajectory start to bleed over into other towns--and I want to get in ahead of the curve again like in Somerville and Medford.Background: I bought the house in 2014 and invested about $30k in the past two years while living in one unit and renting the other.

Sounds swell, doesn't it?

They must be trying to limit the bleeding by renting.  

I would be bleeding money every minute we spent together.

There are times you can save money for sure, but if you are not managing their time and productivity well or don't have houses to work on, you will bleed money.
