Reside in MA-Need Advice

Bought a condo. My unit has a very strong cigarette smell and the previous owner do not smoke. I found out it was the unit above me. They had been smoking on their balcony. But I strongly believe the smell is traveling down to my unit through vent or some hole. I used a flashlight and looked in every closet there is and found a giant hole on the wall. That wall has so much lint and debris because the dryer is there. The inspector didn’t tell me there’s a giant hole on the wall. The smell was coming from there.

Will the inspector pay for the repair since he missed that spot during inspection? He notice a hole under the bathroom sink vanity but not this. I would like some advice what I should do. I regret buying this condo and very upset about it. I am allergic to cigarette smell.
