need opinions about selling a house

[lauralynne]

I'm having a disagreement with my mother in law. They're going ot put their house on the market but...they're both smokers. heavy duty, yellow walls, dirty window smokers. 2+ packs a day EACH. She says that people won't care about the smell. They're going to repaint, clean the windows, and take out possibly replace the carpets. But it still stinks.

Do people care?
Will buyers be turned off? I know I am - I can't hardly stand being in her house for any period of time even when she's NOT smoking in front of me. But I MAY be overreacting...
