Hi @Becca F.
I don't know anyone who retired early/quit W2 at the age of 40 from their stock portfolio. They're all working until at least age 60 and paying lots in federal taxes. I personally know 6 people who have quit the W2 jobs around the age of 40 (picked the right properties and benefitted from appreciation) and age 30 (high income earners who leveraged and scaled quickly) from real estate. I'm reminded from non-RE friends about how I take risks with real estate and I should be try to be mortgage free but when I look at my stocks, I have no control over the value other than to buy or sell.
My experience with RE and stocks is RE has been good to me and the stock market hasn't. Not everyone is cut out to be a property investor and not everyone does well in the stock market. I know people that worked great high paying jobs for 40 years and retired not that rich with a pension. Good job many times equates to a good lifestyle and there is nothing wrong with that.
I scraped together (not easily) a few dollars and leveraged RE and held it long-term with little turn-over but hands on from the start. Using PM now and enjoying it. My stock market investing when working was to accumulate a $100k (back when that was a respectable amount) over a 10 year period only to see a 40% drop. Did I sell? Yes each time a big drop I am not optimistic. I buy stock out of laziness but am more heavy into cash equivalents
RE is more fun IMO but I am more entrepreneurial. I am not corporate type.
So if you are getting 8.5% on a large asset how does that compare to 10 or 20% on a small asset (stock equity)?
