Rehab on a burned property

[Jim S]

Has anyone rehabbed a house that had fire damage? The fire in the property that I am looking at started in the basement. The joists for the first floor living room are severely damaged and the house has a very strong smell of smoke.
My question is....how successful were you in getting rid of the smoke smell? I know they make special paint to lock in the smell. What about the insulation, subfloors, etc? The hvac was running at the time of the fire so I assume the system and duct work needs replacing too.
