Hey @Justin Haughton,
Typically hard money lenders will not lend to owner-occupied situations. You'll see that more with BRRRR's and Flips. High interest rates, interest only, it's designed for acquisition and incentives borrowers to sell or refinance quickly. On a 3-4 unit situation, you'll have to go FHA. This is great because you only need 3.5% down! PMI is pretty pricey, as soon as you are in the 70-75% LTV range, I'd refinance to a conventional.
We bought a 4plex here in Oregon back in August of 2020. We got lucky when we closed since it was right before the market prices in my area started going nuts. We used FHA with 2.75% interest rate and we went a few thousand over asking and asked for closing credit. Because all of the units were vacant, the self-sufficiency test used market rent rates. The mortgage was about $1800-1900 so we were fine.
The self-sufficiency test is a difficult hurdle to get over though, especially if the tenants living there are significantly below market rent. In this situation (as you should in almost all deals) see if the sellers would consider seller financing the property. You may have to give a little (sweeten the pot for them since they feel they're having to compromise with a seller finance request). But it mitigates the financing hurdles you'll find in traditional financing.
Even if you find something that doesn't completely cover your mortgage (a duplex, a home with an ADU, etc.), you're still winning big, and even more than you would if you bought a non-owner occupied rental that cashflows.
1. You're replacing your living expense and leveraging it through rental income. If you're mortgage is $4,500 but rent is $3,000 for your other unit in this hypothetical duplex, your net payment is only $1,500. But that is a huge savings compared to renting, you're cutting your cost in half. And you have to live somewhere. So why not try to find a way to reduce the cost of the most expensive living expense? The best way to look at it is like you are giving yourself a $1,500 raise. Live like you pay $3,000 and reinvest that $1,500 into yourself or save it for another duplex.
2. Tax incentives. You can depreciate 50% of that living space since it is being used as a rental! That's a huge help in offsetting your taxable income. Plus any repairs or maintenance can be written off as well (for that unit).
3. And you're having your principal paid down every month partially by your tenant.
It may be hard to find a 3-4 unit that you can owner-occupy in Southern California, but if I were you and were in a position to where you can house hack, I wouldn't dismiss duplexes or SFR's with ADU's. Live in them for two years and sell them if there's no way they can cashflow them when you move out and reinvest that profit into a cashflowing property. Even if you don't cashflow, the equity and appreciation might be more profitable than the cashflow in your market.
If you could profit $40,000 tax free (since you lived in it for 2 of the most recent 5 years in this hypothetical situation), how much cashflow would you need per month to net the same amount? If you netted $250/door, that's $500/month, that would take you 80 months, or 6.67 years! Then deploy that profit into a commercial property, partner with someone on a larger multifamily, or buy another house hack.
Cashflow isn't bad, but in your market, make sure you are looking at all different angles to see what makes sense to you and your situation.
I hope that helps and answers more questions and doesn't complicate things more. Let us know how your search goes and if you find anything!
