Levi, I actually think there is a big difference between passive stock investing and managing rental properties. Day trading is definitely not passive, but investing into the S&P 500 broadly, without picking stocks - or just "buying a slice of American business" as Warren Buffett calls it - is very passive. I'm actually a huge fan of Buffett, and re: his quote about purchasing SFH's, he specifically said the management of them was what was problematic to him, which is exactly the point I've been making. And apart from an investment he recently made in Sears' troubled real estate assets, I'm pretty sure he is not in real estate in any meaningful way.
And Joe, I actually don't think I'm missing the point, though we clearly have two different points of view. Veering off course here, but it's an interesting point - when you are first getting rich, I believe your income and savings rate are more important than your rate of return. As I mentioned, I majored in math so I understand compound interest (and Einstein's quote was a great one).
But let's say you have an engineer making $50,000/year and it costs them $40,000 to support their family, so they can save $10,000/year. It's much safer and better for that person to try to increase their income to $100,000 instead of chasing outsized returns. Maybe get an MBA to take your salary to $80,000 and have your spouse make $20,000 selling real estate part-time while the kids are in school.
If you keep your expenses at $40,000, ignoring taxes for a minute, then you can invest annually $60,000 = $100,000 - $40,000. If you start at $0 and invest $60,000/year for 20 years at 7%, you'll have $2,632,000.
But if you keep your income at $50,000 and invest just $10,000 over 20 years, then to end up with the same $2,632,000, YOU NEED TO BE EARNING A RETURN OVER 21% (and just for comparison, Warren Buffett became the greatest investor of all-time by earning a 20% return over his 50-year career)! So if you ask me, is it safer and more likely to try to be the Warren Buffett of real estate, or to just get an MBA and be frugal, I think the answer is pretty clear.
And that doesn't even take into account how leveraged you have to be to earn 21% over the long-haul. Or what if you lose your job - having that higher income means you can accept a lower salary and still make things work out, instead of having to sell assets and potentially at a loss. I'm sorry but for any number of reasons, I think earning a higher income and being frugal is the better path.
Now once you have the $2,500,000 in assets, then your investment returns really take over and you don't even have to work, so income and frugality are less important at that point. At that point, you can be content 3% in dividends from stocks, giving you a $75,000 income. Or I can get in touch with you for some killer 10% unleveraged deals and have a $250,000 income off of my $2,500,000.
