Yes, depending on the health of the person.

Sure. However, most people would be very unhappy.

However, they would need to spend less than $34000 a year($24000 from SSA and 4% of the nest egg).

If they had enough income to get be entitled to $2k/month in SSA benefits, then they were living in much, much more than $34K a year. That means they need to take a very serious look at their housing, transporation and health care.

Even if they own their own home free and clear, maintenance, taxes, insurance and utilities could consume a large amount of money. Healthcare is worse…and cars eventually need to be replaced.

that all depends on your life style and what you owe and how much you would spend monthly –no one can answer that but you

Probably not. Most FI planner would probably tell you you need at least $1 mill to retire and suppose you have pay off your house and have no debt. Also, think about SS might not be around in the future or they dont pay as much as they used to. How long she/he is going to live after 65 is also another question because of health care is so expensive for elderly.

Hope this helps
