Smoking in rental unit

[Patrik Kusek]

Hi everyone

I'm am considering purchasing a couple of condos next door to each other. They are in pretty good shape and are tenant occupied with long term tenants. However, on the inspection reports the inspector listed one unit has " a tobacco odor and stains present throughout the unit" and the other has "tobacco odor in unit that seems to be coming from the neighboring unit."  Should I be concerned about this? The tenants seem to be happy and don't want to move. 

I'm thinking about the future and re-renting or selling it. Can the tobacco smell be easily removed?
