17 year old looking to house hack in the next year

[Shane Powell]

I am receiving a settlement of almost $120k at age 21 due to a personal injury lawsuit when i was younger. I am looking into receiving the settlement when i turn 18 so that I can buy a duplex/triplex/fourplex with an FHA loan and live in the smallest room and rent out the more expensive one(s). I'm going into my bank today with my mom to get a secured credit card so I can get my credit built up. I'm going to start working at starbucks to make sure i have steady income. I have a recently started business as well that makes me an extra $200 a month. Should I consider other loan types? Would it be smart to buy with cash? (Maybe a $70k-$90k duplex and put some work into it). I live in Sonora, Ca and would be willing to relocate so long as I'm near a larger city with somewhat desirable weather. Also, how big of a loan would i be approved for if i earn ~$20k a year at starbucks combined with the rental income?
