Possible to avoid Capital Gains Tax by moving into property?

[Account Closed]

In regards to the IRS rule(s) that allow single/married individuals to realize a tax free gain on real property sales up to $250k/$500k so long as they live in the property for 2 of the past 5 years, is it possible for an investor to buy a house, rent it out to tenants for many years, turn around and move in to the house, live there for 2 years, and then sell it and avoid paying the capital gains on it?

@Account Closed, 

What do you think ? If there is a hack like that, IRS already has a remedy.

There is something called non qualified use. 

So you have to prorate your gain between taxable and non taxable gain.

There’s is no non qualified use if you buy a house, live in it for 2 years, and rent it out for 3 years, in that order.
