I've been fairly lucky, foul cooking odors and cigarette burnt carpets biggest headaches.

Doing it the way Nuhan described above, shouldn't fall foul of Dodd-Frank.

There are some paint strippers that are non-flammable and odor free.

It is common to grab a roll of blue painters tape and tear a 1" piece off to spot fouls that need to be fixed in the industry.

Exhaust fans should do just that, exhaust foul or humid air outside of a space.

A lot of people I've spoken to with experience selling houses suggested that I try to do FSBO but since this is my first time, I really wanted the learning experience of working with a realtor so no harm no foul.

So with the balloon experience in hand, maybe that smell isn’t stale, rather it has kept it’s odor fidelity all these years!

Smells and odors, especially urine. 

Residents who wish to be "grandfathered" and continue smoking will be allowed to do so; however, if odors from someone's smoking can be detected in another unit or common area, then the Board can permanently remove the "grandfathered" exception for that owner.  

Hire a company that has special services for pet staining and pet odor and deduct from the deposit at the end.In my opinion a pet fee does not cover damage to the property.
