Stable income: Somewhat stable

A window cleaning business can provide a moderately stable income source for most people who try it. Based on online research and common experiences, individuals in this business tend to see decent baseline earnings, but there can be some unpredictability in income from month to month. While some months may be consistent, others may bring fluctuations in revenue. I'd rate it a 2 out of 3 because there is potential for a reliable income stream, but it may not offer the same level of stability as a traditional job.
