@Henry Clark I think 'your thinking' is sound. 

Possible perhaps but I don't think probable.While there have been some exceptions and special programs that perhaps pay a bit more than market rent, I don't think it is that common.

Understand your risks and think through your worse-case scenarios before proceeding. 

But I don't want to be living with strangers, I was thinking if I make my own room(something small like in the garage). and only sleep/be at the house half of the time will I still be considered a primary resident and will that be okay with FHA guidelines as long as I don't tell them?

Why do you think purchase contracts are so long and have such small print?

(Which depends on how much money I need to save up for) I was thinking about doing that for about 3ish years.

I realize this is a nice thing you are thinking about.
