Most of the retirees in our village have invested their money in real estate particularly in apartments and houses that are for sale. The rental serves as their subsistence allowance. That is also what's on our mind when my wife retires from her job 4 years from now. We plan to buy a lot and build an apartment with 4 units to be rented out. It is scary to invest in a business because we had already tried that before and our experience was not really encouraging. With the real estate, whether it earns or not but at least the invested money seems to be intact with the market value of the real estate.
