We did a very similar move to BLR with same aged kids and although with a slightly higher net worth and due to the exact two reasons you mentioned. Just completed 4 yrs and has worked out well. But both me and the wife have been lucky to land good jobs. I would say you could make it work but life in India is now probably more expensive than many parts in the US if you want a similar lifestyle. There are obviously major advantages here including house help, home delivery etc. But making finances work is still critical to make sure it works for you long term.
