The solution for me was buying cheap houses in Detroit. For $30K you can buy a house that nets you $500 a month ($800/month rent minus expenses) so for example if you save $150K from your job that buys 5 houses yielding $2500 a month (or if you had $300K savings, $5K a month). That was the way I was able to replace at least part of my income and venture off to the land of not having a salary to free up time to pursue other projects.
