Next best strategy after house hacking

[Account Closed]

Hey everyone, I recently moved to Dallas and signed a short term lease for an apartment with the plan to move into a 2-4 unit property & househack in 2018. 

However, I've been searching online & driving around north Dallas & Dallas proper many times and I haven't seen the first 2-4 unit property. 

Some buildings I saw that resembled triplexes ended up being condos/townhomes. Also, the only duplex I could find online (Plano) was being sold specifically as a "half-duplex"- meaning you could only own and control half of a property. 

Could any Texas investors please point me in the right direction? If I can't find a small MF to househack, what's my next best option- buy a cheap single family to live in & use the rest of my income on REI?

Thanks!
