Power washed, painted and cosmetically I removed the popcorn ceiling throughout the house.

Damage is pretty broad, is at a scratch, or shattered.Is the car lowered, was he driving at the legal parking lot speed?

Outside its definitely a plus....but inside I think its a wash unless you are a pro and bang that stuff out real quick..... the prep and the clean up wipes much of the time gain.

Power washed and painted exterior, removed trees, new windows, painted front door, updated garage door and back door, added door entry from garage into house, new paint throughout the house, renovated 2 bathrooms (one of these bathrooms was a 1/2 bath that we converted into a full bath by combining the adjoining closet and rerouting the plumbing), added a kitchenette/kitchen in the basement.

Exellent lists.I put vinyl under sinks, dishwashers and most washing machines.
