As suggested by the other posters, there are two main approaches to the business. First, you can buy rental properties to hold and rent. Second, you can “flip” properties - buy them, fix them up, and sell them.
The trouble with the first approach is that it takes a long time to build up gains, and you have to be a landlord.
Of course, the second approach is somewhat riskier.
But the thing about real estate is that it’s not as efficient as the stock market. If you know the market well, and are patient and thick-skinned, you can get a bargain.
So, if I were in your position, I would consider doing it, assuming that you are interested in real estate.
You’ll need to look at lots of houses in your area, so you know the market really really well.
IMHO, the best way to get a really good deal on a house is to find a house that’s overpriced, and has been sitting on the market for a while. Then hit them with a “low-ball” offer - something way under the market value. Of course, most sellers will be insulted and blow you off. But once in a while, you’ll hit, for any number of reasons.
Another approach is to look at public records and find out homeowners who are getting divorced or having financial problems. Then approach the people with a quiet, all-cash offer for their house. (Yes this is kinda scummy.)
You need to find houses that need only cosmetic repair. If the house has structural/electrical/plumbing problems, it will likely be too expensive to fix and still make money.
You will also want to line up financing so that you can come in without a financing contingency. Sellers always worry that buyers will flake.
You need to learn how to sell a house too. There’s a lot of issues here, but the main thing is - don’t overprice it!!
