@Jon Schwartz beat me to the punch!
But I would just like to piggyback a little more on what he said. First off glad to see a neighbor on here, we're located in newport beach so you're not too far away. I will say that you won't really see multifamilies in irvine, you usually find those type of properties in the older areas on orange county like santa ana, fullerton, or along the coast where you're dealing with a much higher cost. You will find much more availability of multifamilies in Los Angeles but just make sure to decide where in LA you'd like to live as safety and environment can differ from street to street and community to community rather quickly.
Also, it was touched on in the last comment but there's a very very good chance you will not see positive cash flow, at least not until you move out in the future. Prices are much too high and your down-payment will be far too low for it to end in positive cash flow. Now once you move out in the future, you'll more than likely see some cash flow and you'll have appreciation to help.
One thing that hasn't been discussed will be the eviction moratorium, rent control, and california just in general being a very tenant friendly state. That is just something you absolutely have to keep in mind, ESPECIALLY if you're going to be living in the property as well. This is not to scare because a large portion of the risk can be avoided by good tenant selection but it's still something to consider.
We personally invest in Cleveland where we rehab and hold or flip. There's positives and negatives to each scenario so I'm just making sure you see the whole spectrum.
