Which verb is best in this case?:
If I won €1m, I would finish paying/repaying/paying back my house.
Ps: Can we ever use the structure "finish to do smth"?
Will, in the US, we'd say "I'd pay off my house."
I can't think of a time when "finish to do" would sound right, but every time I say "never" someone comes up with an example. Generally, though, it's finish Xing.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
