Someone can use foul language and call you names and that doesn't immediately invalidate a lease.

Smoking not only leaves an unpleasant odor, but it can also pose significant risks.

It really boils down to "trust", if a seller believes that you can perform as stated by the contract in a timely manner than no harm no foul.

If you don't plan to enforce it, then get rid of the rule.The entire house needs to be deep cleaned, then you paint with an oil-based primer to seal in the odor and nicotine.

This week, I had someone from our team review one of our higher end units and he reported back that it had strong cat odor and dog scratches.

The story in a nutshell; I learned a lot about how to remove cat pee odor, and also that I will never have a male cat.

If it's an empty house, it doesn't really matter how long it takes you to get a deal, no harm, no foul.

Even though carpets are professionally steam cleaned between tenants it is not unusual for someone who does not have a pet to walk in and comment about a pet odor (and this does not have to be from animal "accidents"; but simply from a pet living in the area.)Ironically I do animal rescue myself (cats and dogs) so no carpet in my house! 

Does she have pets - any pet odors (owners don't realize that pets have an odor).Have someone give the home a good look and give her an honest opinion about anything negative about the house.

SANITIZING AND ODOR REMOVAL (IF ANY) ARE NOT INCLUDED HERE AND WILL BE PART OF THE RESTORATION PROCESS.5.
