Hariharan,
I love what you are planning to do unfortunately no one can tell you the perfect plan for you it comes down to your comfort with debt and leverage its an emotional decision not math.
What is guaranteed is your long term 25 year plan will not work the way originally planned.
Leverage is the double edged sword naturally most investors love it and they only hate it when it turns on them.
When Ramsey pops up in your feed think about what happened when he went BK in real estate? Was he just unlucky in real estate, not a good operator or could it have gone the other way ?
Real estate is not risk free it's just a reality your long term planning is truly impressive but realize life is going to happen.
Caveat, I did the infinity leverage approach when I started but never take it for granted you never have full control in this business its just an illusion get comfortable with it and you'll survive and thrive.
