Hi Jason,
A lot of this looks good, but I'd just note a few things. Non-owner occupied loans usually carry 1 or 2 % higher interest rate than owner-occupied. I don't think legally we can "quote" rates over the phone or internet, but the last non-owner-occupied loan I saw was in the 5% range. You can talk to a mortgage broker, bank, credit union, or any lender about this for more details. Message me if you want a referral to a good mortgage broker, I know a great one in Bakersfield. Anyway, you can always get an owner-occupied loan for a multi-unit, but you are promising to live there yourself (for at least 1 year I think). If you don't want to do that, then you gotta get a non-owner-occupied loan, which is has a slightly higher interest rate.
Also, as a general tip, I'd say the best ROI I see in multi-units in Bakersfield tend to be properties in the 93305, 93301, and 93308 zip codes. These tend to be older neighborhoods that have a lot of multi-unit properties, and therefore make for a hotter rental market, due to older zoning. My favorite area for these is the 93305 zip code for sure. I'd also echo what others have said about 2 or 3 bedroom units having longer-term tenancies and less vacancies overall, compared to studios or 1 bedroom units. I'd also recommend getting in touch with a local real estate agent that can set you up with MLS access so you can see whats out there - Loopnet is good but it's designed more for for large scale commercial, not so much for small scale residential income properties like duplexes, triplexes, fourplexes, etc.
