New investor seeking advices.

[Rimane Tientega]

Hello everyone, my name is Rimane I'm 23 and I'm new to this world. I was planning to buy a house with an agency who helped people apply for a grant and take care of the paperwork. But they told me I should look for a condo not a house. 
For them , I'm not able to borrow a lot of money for the house , because I don't really have a high income. But someone told me to ask them about the FHA loan. I'm a little bit confuse , why my counselor didn't talk to me about the House hacking.
So now I want to know if anyone can use this technique and what I must told her exactly?
