First property looking to house hack

[Dallas Hoover]

Good evening, everyone. 

My name is Dallas, looking to acquire a duplex or triplex for my first property to house hack.  Using Fha of course, what are some problems a 19 year old would run into? I'm 6 -8 months looking in the dfw area like Dallas or Royse city area Tx. How much do is enough for the down payment cause I know it might not be 3.5% down.  Is the market In a good place right now or it is in shambles?
