On a 100 year old home with 12 coats of peeling paint on it, then the prep costs can be very high and can easily exceed 50% of the job's labor cost. A 2100 sq ft two story home could easily cost $1000 just for the labor to prep for the paint job. That number could climb too. Throw in lots of caullking or window glazing, and you could be talking a couple or a few hundred dollars more for labor.

I would love to know the total sq footage of that 10 room house that you charged $9000+ to paint. Yes the wall sq footage was 5900, but $1.80 per square foot of wall space is a bit high for a residential repaint IMO. Take for example, I charge 1.75 sq foot for 10x10 room with 8 foot ceilings.
