Don't go into a lot of debt to start investing in real estate.
If you want to buy rental property, you should save up enough money to pay the repairs to the property, down payment and transaction fees.
You can buy real estate investment trust shares like stocks. You can also buy exchange traded funds that focus on real estate, with some specializing in commercial real estate or health care real estate. These investments require a few hundred or few thousand dollars, however much the brokerage requires to set up an account. And unlike a rental house, you can sell the shares and access the money quickly.
