My dad did pay for my undergraduate degrees (I earned both a BS & a BA in 4 years) and my senior year in college he bought me my first car, a beater, (after somebody hit me on my bicycle...-fortunately I was not seriously hurt-). Looking back that was good because when I got out of college I didn't have any student loan debt and I had functional transportation. But beyond that? No help. Not even spending money. For that I had part time jobs on or near campus.
I went to graduate school on my dime (and made a 4.0 because less than that was disrespectful of my own money). I went straight to work full time after college graduation, as in the Monday after graduation. I made peanuts for a number of years (as in less than 20K annually...academia does not pay well!)
As far as what I do I'm a consultant in healthcare. Like Neil I earn about $85 hour per client per contract. I also have 45 rental units. The annual rents are about 140K to 160K depending on the vacancy rate. In a full earning year consulting I earn roughly 200K. So 200K consulting plus 150K-ish gives 350K, of which the rental income portion is passive.
I first made 150K+ at age 32. I have consistently done that ever since. By age 35 I was supporting my family solely on my income alone. This with a bachelor level education. Also at 35 I got serious about real estate investing.
So that is just the income side. Equity is about 1.2M on a portfolio worth 1.8M or so in the current markets (I'm regionally diversified). So I do still have debt service on about 600K, but the portfolio carries that easily. Many of my units are free and clear. My net worth is over 1M. So I'm a millionaire, but not a multimillionaire, not yet.
I could quit tomorrow and live on the passive income, but I'm saving for college costs and optimizing the portfolio (accelerating debt service). Once I pay off a handful more houses (this year and next) I'll drop out of the workforce for a while to be home with my kids full time as they get ready to leave the nest. And I'll do it with a 100K passive income. I will likely take the occasional part time consulting client while I put them through college. Once you have children your priorities change.
