I want to learn about real estate business and stock trading. Thanks to everyone sharing for less experience. I'm a newcomer
You appear to have taken a wrong turn then, this is an IT community...
There are so many sites about both that you must be very new not to find them. No offense intended. This site isn't about RE or stocks so the first thing to do is to lock away your checkbook and start your learning. Note "How to fish" at https://humblestudentofthemarkets.com/
As to RE, welp, that changes with time and location. There is no magic there. Thoughts? "Never own a home you don't live in."
