Pramod, thanks for reading. I'm glad you found it useful. As it so happens, I have another article on my recommended books: https://themakingofamillionaire.com/26-best-books-to-build-wealth-8a784c8b4
In terms of what to invest in, there are many criteria such as location, price, returns, age of property, type of property, method of investment (direct ownership or passive), etc. It is not something I can really sum up here, and it depends on you quite a bit, your knowledge, your appetite for risk, etc. I have a collection of my best real estate articles here that you can look through for additional information: https://buildingarks.medium.com/want-to-make-money-in-real-estate-4884bb49d651
I'm happy to discuss more once you have started looking into this information so we have a good place to start.
The most important thing to remember is summed up in a quote from Warren Buffett: "Risk comes from not knowing what you are doing." So take the time to learn before jumping in.
