I am looking for something that would rent easily and quickly and also mostly looking for appreciation since I know getting positive cash flow is next to impossible in the Bay Area market.

oh yea BRRRFiguring out the total return would seem impossible using ROI, but all you need to do is think about it in terms of things that put money in your pocket every year. 

In addition, the owner of the home must not own more than three single-family homes.3) They are unable to provide sufficient documentation, such as the emotional support animal letter, that verifies the ESA is necessary for their health and well-being.4) The tenant provides fraudulent documentation attesting to their need for an emotional support animal (usually a fake emotional support animal letter).5) The landlord can demonstrate that making accommodations for an ESA would impose undue financial burden or logistical burden. 6) The animal is destructive to the property or displays threatening behaviors that could put other tenants or yourself at risk.7) The size or nature of the animal makes it impossible to house safely or humanely. 

Remember, you are occupying one of the units...it would be impossible to cashflow in that scenario.

Getting smoke odor out of a home is nearly impossible  Months later, the smell of smoke remained despite attempts to mitigate and eliminate this odor.  

Carpeted floors above would also helpBut you have sound and vibration and vibration is impossible to get rid of.

@John Brown this would be next to impossible for us to know.  

It looks like it's impossible for me to be successful in all three at the same time.

Also I am self employed and it is almost impossible for me to find reasonable conventional financing, almost limited to these type deals or owner financing.

I was wanting to lump all the money together and buy one investment property, but it sounds like it may be complicated or impossible to keep track of who owns what percent of everything if it's all mixed together.
