I'm looking to build a wholesaling business around SFHs here in Southern California (Riverside County, specifically), then expand in time to MFHs, possibly commercial.

I am also nervous about it not cash flowing at all but I think buying in southern California and holding long term is an almost certain strategy to build wealth.

There is not a bathroom in the building so unfortunately only option is a Porter Potty.

Option 2: Purchase additional properties and build portfolio I know that there are some tax implications to no having the mortgage payment to consider.

I am open to other scenarios.We have access to $200k ish in equity in our primary.We will soon have access to another $100-150k for retirement/investing/IBC/etc.I would like to move into my young family into a (new build or fully renovated side by side) duplex.

I have been investing in Toledo, OH since 2009 and owned 2-12 unit buildings and find they are way too hyped (read lots of guys from BP want to pay too much for them) and the reality is residents in Toledo are ultimately seeking a house with a yard and a garage so as soon as a resident improves their financial situation they move into a house.

You should build versus buy.  

You need to build your team for your real estate investing business.

Basically, if you are committed to this investment thing, you will need to make some uncomfortable/hard choices to eliminate the credit card debt and lower your monthly debt.Once that goal is complete, you can begin practicing habits to live below your means and start building up your savings. 

The ability to generate money for laundry at a 2-4 unit building is totally dependent upon the tenants you have.
