I too believe my choice to retire early should not penalize our kids with a higher EFC. We have a firehose of cash coming in right now, so it's hard not to work OMY to fund what would otherwise cost our kids substantially more time. We're almost done funding the the oldest's account and we'll tweak it in ~5 years if needed, depending on how the market is doing.
There are ways to hack educational costs, but usually it's a tradeoff. College is about more than just a piece of paper, it's also about learning, instilling a love for learning, building connections and relationships (friendships to jobs), etc. Some of the ways to reduce costs compromise these other goals. I've had community college courses, good state university courses, and courses at a top 10 school. The quality of education improved substantially for each level up. Knowing this, I'm not a fan of encouraging my kid to take a scholarship at a state school if they don't want to go there. Many top schools don't allow athletic scholarships (and that's a dicey strategy to employ anyways). My family has a military background, and knowing what I do, I'm not comfortable encouraging them to go into the military for the free education. We earn more at our current jobs than we would we tried to get a job at a university for the free tuition. Etc. But it's not mustachian, so I don't usually advertise our plans to fund most if not all of college. That all said, yes, I'm looking into how to reduce our income to lower our costs for FAFSA, but 1) some places use CSS, and 2) we'd need to manage to keep the income low for 7 years.
