@duffy44 So what amount would you quantify as substantive?and are you planning to FIRE in the US? Or coming back to India for retirement?
Based on the information you've given:
A. Your savings rate currently is roughly 25% of your salary, considering you don't pay for rent or food you can try improving.
B. If you want to have better returns on your portfolio you will have to expand more on Small or Midcap MFs which come with higher risks.
C. In my experience, if you're not in Tech or in business the RE part of your goal is difficult to achieve especially if you're going to immigrate to the US and start from zero at 32, it only gives you only 13 years of earnings. Not trying to deprecate your dream, just setting realistic expectations.
