Real estate business is one od the ealry businesses in the world. And it's value is increasing everyday.
If you buy a flat the value of flat increases and you get rent as well.
If I invest 3000$ in real estate in developing country how much I can make in 5 years?
I make as high as $350 monthly working as an estate manager back then in 2018. My boss had a lot of houses that he needed to be rent out and the duty was placed on it. It was easier as all I had to do was talk to my friends that helped me to market those houses.
