Hi Estevam, thanks for your comment in my profile. So. about your question above I didn't understand property because as you know everything in this great language depend to context. This way I'll try helping you ok!
We can say "Do you have Something this means like " Você tem ( no sentdo de posse) and when we use got, depending to context, it's no translated. It's a way that speakers found to talk in informal way. Did you got it?
For exemple: I have got to go - eu tenho que ir.
I've gotta go - é a mesma coisa mas para a pronúncia fica mais sonoro e mais rápido ..... Then, I think it's that..... Take care.
