Using stock footage models for affordable housing business

Hello, I’m starting a business targeted at housing affordability and want the local community on board.

I have an ad concept for 3 small SM videos
All runnning with the same theme.

E.G. Barista making coffee footage

With a narrator that says, This is Paul, Paul is 32 and cannot afford to move out… at least his mum still does his washing. Then Cuts to company logo.

My question is, is this permitted with stock footage models?
I am new to using stock footage and The FAQ left me unsure,
My narration scripts features no company endorsement,
but I was unsure if giving one sentence storylines along the theme of not being able to afford a house would be considered unacceptable?

Any answers would be greatly appreciated,
