Material fact - what should be disclosed

[Patricia C.]

hi all

I recently purchased a condo in Norwalk. We have been having issues with the neighbors next door with smoking cigarettes. It’s coming into our unit.. we are going to the board come January.

We are probably going to end up selling it. My realtor is saying we have to disclose that we can smell cigarette smoke when selling or we can get sued.. I’m so confused by that. If that’s the case, we could be suing the seller for not disclosing this info to begin with. 
And now I’m afraid of loosing $ reselling cause of us having to disclose.

Can anyone help with this? Thoughts
