Stable income: Somewhat stable

I’d rate it a 3 out of 5 because while carpentry can provide a decent baseline income, it often depends on the availability of projects and client demand, which can be unpredictable. It's not as unstable as some side hustles, as skilled carpenters are often in demand, but it lacks the predictability of a regular paycheck. It's not a 2 because there is a consistent need for carpentry work, but it's not a 4 because the income can fluctuate based on market conditions and project availability.
