Hired a pro to paint interior and exterior of my house. It was new construction. Outside is approx. 50% board and batten, also had cedar beams inside and out on porches. Outside was 3000 and inside was 8000. this included prime and paint all base, doors, closets and cabinets. All paint and stain was Sherwin Williams, high quality stuff. I highly recommend getting pros you dont have to bird dog and punch over and over! May cost a little more initially, but you'll be alot happier with the results!!
Pricing by the square foot for painting walls is typically between $1.75-$2.00 based on the floor plan, which equates to about $.55-.75/sq ft of overall wall space. So a 10x10 bedroom would typically cost between $175-$225 for the walls alone. Ceilings are generally between $.75-$1 a square foot, so another $75-$100, and trim should cost at least $1 a linear foot, but prices up to $3 a linear foot are pretty common, so trim for that 10x10 room would add between $75-$200. And doors should cost between $20-$50 per side.
Whether doing it yourself or hiring someone, buy the best quality paint you can afford; it lasts longer and in some situations requires only one coat of paint instead of two.

If you want to upgrade your home’s interior, or if you’re starting with a blank canvas, find a painter nearby so the project can go smoothly. Interior painting contractors and companies work hard to turn your house into a home. Hire a professional painter to add a fresh coat of paint on your walls, ceilings or window trim in any room in the house. Browse through the top-rated painters, read their customer reviews and ask for a cost estimate.
Take for example, I charge 1.75 sq foot for 10x10 room with 8 foot ceilings. By my calculations this would cost $175 with floor space sq foot, but with you method, it would cost $576.00 That is outrageous. Of course I didn't subtract the windows and doors, which is another thing that makes no sense. Cutting in around those windows takes more time, then just rolling a wall.
"William and the entire Edge team were such a pleasure to work with. It was a joy to find craftsman who take their work seriously, listen to the homeowner, give fair prices, and leave your home better than they found it. I recommend William and the edge team without hesitation. They repaired all of the damaged wood around my homeâ s exterior and sanded and painted potion clean upAfter themselves immaculately. I cannot recommend Edge strongly enough and without hesitation, I would hire them again."

If you're thinking about selling your home, you might want to repaint areas that look especially worn, dull or chipped so your house looks fresh and new to potential buyers. On the other hand, it’s possible some potential buyers will repaint the home upon moving in. So if you have a limited budget, your money (and time) might be better invested in other types of home projects, such as remodeling your bathroom or kitchen, installing new floors or fixing broken appliances.
