A more user-friendly option is a water-based “latex” paint, which blends acrylic pigments with a thin base for easy application with a brush or paint sprayer. Although many water-based interior paints are promoted as one-coat wonders, there can still be a need for an initial primer coat followed by one or two coats of latex paint. Water-based paints are very low in VOCs, which means minimal odors during the drying period. Most spills can be wiped away without the need for chemical cleaners, and clothing containing latex paint can be laundered in water and detergent. Water-based paint is a good choice for first-time DIYers and their younger assistants.
Some basic interior paints are sold in bulk, often in neutral colors such as white or beige. These can be very economical if the home’s color scheme is not a major consideration. However, many homeowners prefer to apply customized colors to match the furnishings or create a specific ambience for each room. Because of advancements in the industry, many manufacturers now offer a dizzying array of colors, from cool pastels to bold metallics.

On average, expect to pay $0.60–$1.60 per square foot for exterior painting. The average for painting labor across the country is $30–$40 per hour before you pay for paint, painting supplies, location costs, and equipment.

It's up to you. Outside is much harder because it requires more prep, patience, time, help, money and of course, effort. I have been painting my own houses and rental properties interiors for 20 years, and I painted the exterior of one, once. I then had it promptly done again by professionals who said it would have been cheaper if they didn't have to undo my work first. My advice is to get pros for the outside because everyone will see it.
