Buying real estate for short-term or long-term rentals is buying yourself a second job.
If you want something more passive, consider investing in several different real estate syndications. You can find them on CrowdStreet or FundRise although I believe you will get into better deals if you join a local investor group and learn from the experienced members. If there isn't a group near you, I'm enjoying participating in www.506investorgroup.com
This style is probably only practical if you already have a net worth of at least $1m. The best book I've found is Investing in Real Estate Private Equity by Sean Cook.
I think it is reasonable to expect a diversified portfolio of real estate syndications to return 10-15% annually although it will be bumpy and your money will be locked up for years.
