I live on the East Coast of the U.S. -- New Jersey.
The estimates that I got were for a 2 1/2 story detached single family home with old-style aluminum siding and an open wood "overhang"(?) of about 20 inches on all 4 sides; and a detached 1-car garage with wood siding. I had everything painted white -- walls, trim, etc. -- so no complicated cutting or multiple colors etc. Plus, no shrubs, plantings, etc. around the house to worry about. They spray painted most of it. And, I picked the $3,500 estimate and they did it in 2 or 3 days at the most.
Shortly before that paint job, I had another 2 story, 4 BR, 2 bath, colonial style home with attached 2-car garage painted. That one had asbestos siding and was painted one main color and separate colors for trim (white) and doors (green). The company that painted that one did it for $3,000 (including the paint). They mostly spray painted it and did it in 2 days. That house was bigger and more complex than the job on the other house above that I described. But, the company that did the colonial for $3,000 gave me an estimate of something like $4,800 for the smaller 1-color house, so I didn't use them.
