I had desisted of the idea of house hacking due to the fact that most small multifamily properties are  the most desirable areas(based on my experience).

I need some helps and advices on my next move.I'm thinking to sell my rental property to get $150,000 cash in hand, then look for a Duplex/Triplex in Garland, Grand Prairie, Irving, or Arlington to do a House Hacking method to put only 5% down.

Sounds like you may have a shot at living for free when you move into your next house hack. 

Also look into doing a live-in-flip, it's a great house hack alternative in this market.

I am thinking of house hacking through the use of an ADU since I live in a more expensive area than most.
