Heavy smoker rehab

[Jeff B.]

Looking at a house that has been owned by very heavy smokers. Overall the house is in poor condition and is a short sale. Nothing that scares me, except the fact that the walls, ceilings, heating ducts, windows, EVERYTHING has a very heavy coating of cigarette smoke. What is the best way of remediating the smoke? I know I can use Kilz on the walls and ceilings, but what about the ducts and the insides of everything else in the house? Is it something that I'd have to get a company like Servepro to come in and do a thorough cleaning or are there other options?

House is in an area of 130k homes (all similar) and has a shortsale price of 70k. Rehab is probably 12k-15k plus whatever the smoker cleanup would cost. It would likely rent for 1100.
