Rehabbing old St. Louis City fire damaged brick house

[Cameron Hillebrand]

Hi! I'm going to get an old St. Louis City brick house under contract this week. The only problem with it is that the kitchen had a grease fire. There was no structural damage. The entire house smells like smoke, and there is a layer of smoke on the surface of everything in the kitchen and rooms adjacent to the kitchen.

I am hoping I can prime paint the walls, replace the floors, and rehab the kitchen. Purchase price is 11k. Rehab cost is around 10k. Rent is 950/month. What surprises might I encounter?
