There are many cleaners available for pet odors, smoking, etc. that you can also investigate to help you with minimal work.
Good luck I've included a link with stuff I've used.

1.Remove any soft surfaces like drapes, upholstery, carpet and wall paper. You may be able to remove the odor from drapery by having them dry cleaned, but you will never be able to totally remove smoking odors from carpet or upholstered furniture no matter how many times you have them cleaned. Wallpaper is porous and absorbs odors. Remove it as you cannot remove smoking odors from it 100%.
2. Have the ducts cleaned and change any furnace filters.
3. Paint every painted surface, using Kilz as a primer. If you just paint with no primer, you will get nicotine stains seeping through within a few months.
4. Change all light bulbs and tubes. Nicotine coats all surfaces and as the light bulbs heat up, they act as fragrance diffusers of smoking odors.
I hope this helps!
Hope this helps!
Dan's advice about encapsulating the odor is good. However, before you do that, thoroughly wash and clean all the hard surfaces. If you use Kilz--a very good product, by the way--use the original formula.
I've also had some success with ozone machines. You have to use a heavy-duty one--you can rent or buy them. Check with your Realtor--he or she may have a source. Then you have to blast the home. They work well on things like cooking odors and smoke. (They don't work as well on things like cat urine. I know; I've tried!) I bought one from this company: http://www.maxblasterusa.com/ There's also a lot of good information on their web site.
The main point is that you can't just cover the odor up. You have to remove anything that's capturing the odor. You have to clean and then encapsulate hard surfaces. And you have to get to areas (with an ozone machine) that either you overlooked or you couldn't reach.
Having said all that, if the house is a good one--meets all your requirements--and it's priced low enough to compensate for the time and effort you'll put into getting rid of the tars, the odor, etc.--certainly consider it.
Hope that helps.
Most of my buyers just pass on smokers homes.
Unless you want to completely redo the house find another. It could be weeks getting all of that done and you feeling sick from the smell all of that time. Then you have more time waiting for the paint smell to go away.
Don't forget to change the furnace filters.
