It's probably too late to get into real estate. The market is high in most areas or at least back to where it was pre-2008. You would be buying high, adding more money to fix it up and then you can't sell it if the economy crashes like 2008. You can rent but when the economy crashes even renters can't afford reasonable rent so then you have the house sitting there while you are paying a mortgage, property taxes, insurance and maintenance. When your mail person tells you about how many houses they bought and are renting them out you need to get out of real estate. In the Tampa Bay area all of the professional house flippers are either buying the few properties at decent prices that are left and then turning around and selling to new flippers without remodeling or they are making money giving advise to new flippers. My wife and I bought a second property several years ago as an investment and for vacations since it's near the beach. The seller bought it in 2005 from a flipper for several hundred thousand more than he sold to us. We might be able to rent it on a short term basis to pay for property taxes and insurance for the few people who can afford a vacation in an economic crash.
Baby Boomers will be selling their larger homes for smaller homes if they can get one for a reasonable price so all of those homes they are selling will be flooding the real estate market and make things even worse.
But, like you said, if you are smart and you really know what you are doing then you may come out ok in real estate in the current environment.
