The BEST way to get started in my opinion would be to buy yourself a home to house hack first. The benefit of buying something as a primary residence is that lenders are much more willing to lend to you for low money down. If you are house hacking it, you will at the very least significantly decrease your expenses (which will build your assets assuming you're saving that extra money).
I know you said duplexes are hard to find in your market. Even if you can't find duplexes, I'd look for a SFH with an ADU, a SFH you could turn into a multi-family, or buy a SFH and rent the rooms. Even if you have a family and this doesn't work for you, you could still live in a SFH and rent out the garage for storage or rent out the driveway for parking, etc. With limited options, you are forced to be creative! Even in the worst case scenario there, I still think it's smarter to buy a primary residence first so you can get in for a much lower down payment.
