A- it's a complicated issue, and there will always be someone crying foul (especially in frisco!) 

Concrete is porus so it can absorb odor.

On both of Brazilian goals there was foul on Croatian players in action before goal. 

We have seen it recommended that walls & ceilings be washed with special soap and/or vinegar and lemon water to kill the odor.

My suggestion which may differ from others is you should let the seller know up front what your intentions are so that in the event you dont sell it then no harm no foul. 

This is not tie up a house with no ability to buy it and if it doesn't sell no harm, no foul.

What if I did not like the colors, music, odor of there incense.

One thing we did discover is (this property doesn’t have a basement it’s on a slab), because of the pet urine soaking into the concrete after cleaning, bleaching… we sealed it with Kilz oil based sealer to lock in/out the odors and ran my Ozone machine for a month to help with the smell.The Bear Paint distributor for Home Depot said we should have used water based Kilz and not oil based.

Investor committees are put together lawyers come in .. they oust the GP... now you have a lawyer and investors trying to run the asset they fail miserably because the lawyer is milking the deal.. then they just all cry  foul and start getting the DA involved 500 complaints to DA they have to do something they charge the 2  not just one but 2 owners of the company with criminal... one guy got 6 years in Folsom the other 9 in San question..

The corrosive nature of soot is driven by the materials that burned, as is the odor.
