I am asked to write on "things you want to have done".
My interpretation of that question is I have to write on things I want people do for me, not things I wish I had done in the past. Correct ?
Most of the examples I found online presents sentences like this one :
"Thirdly, I should get one of my apartment’s entrance all reconstructed because it is literally falling apart."
Subject + (modal) + get/have + object + past participle + (by agent).
What I'm wondering is if I am allowed to combine have and get, as in the next sentence :
"Fourthly, in that apartment, the bath tub is also falling apart so I have to get it replaced. "
Is have to considered as a modal so the sentence is in fact a passive causative or is it incorrect to use have to the way I did ?
