Could look at Food Truck rental spots. 

With the right tools and a bit of hands-on management, you could effectively manage the property yourself and cater to this steady stream of potential tenants.

When I'm not listening to podcasts or doing something business related, I am usually outside, dancing, or learning how to make some tasty new food! 

I don't know Orange County too well to answer your questions, so will just add a few other tidbits as food for thought. 

@Rob Ibarra No matter where you look, start with the zoning and make sure you can have a food oriented business at the property. 

I also cater to how they do things if they already have existing books.

You have $606 after tax dollars to spend on the rest of life's expenses, including investing, buying flowers for your significant other, cell phone bill, water/electric/vehicle expense/food/childcare/hair cuts/vacation. 

It's like asking what the best food is.

It's because you didn't get rid of all the food and drinks left on the studs by the electricians and plumbers, before the sheetrock crew does their thing. 

Food for thought: it is easier to get a loan of any sort on the owner occupied part, to include HELOCs.
