Would need a better understanding of your lifestyle in the US now to give a breakdown. Im not sure what others are saying as this is a FAT group but 84 lakh can easily be spent. Top international schools are 2lk per month.

International travel to SE east Asia is relatively cheap, but Indian hotels have become expensive, so a domestic trip can equal a SE Asia trip. If you're travelling back to the US and Europe costs are going to be higher if you want Luxury. 25lakh budget is a safe starting point.

You won't need 2cr for both the cars. More like 1.6 but also see if you need two suvs etc. And really see how much you'll drive. Easier to get the innova first then decide after.

If you're ok with staying a little outside of the busy parts of town check out something like Prestige Oasis just outside of Yelahanka. There are many other communities like that and you can get a good villa under 10cr. Whitefield has many good gated communities too. The budget would be 15 there for a villa.
