21 and what rental portfolio to start with?!

[Josh Brosius]

I'm 21 and out of college with a full time job and saving for a down payment with help of a grant from my bank. In ten months the bank will match up to 7,500 dollars that I save which I plan to use for a down payment. I would like to live in a duplex and house hack then rent it out when I move to my own home. The dilemma is I have been looking for over a year now at what is out there and there aren't many small multi-families for sale in my area. Especially ones worth buying. I ask should I try doing single family rentals. Buy a house, fix it up, then rent it out or should I keep looking for multifamiles. I'm not in the hunt for get rich quick but to build wealth for my family when I'm older. My future self. I would love to get my rental portfolio started anyone way possible. Thanks for the help
