Keeping money in my pocket vs. paying the tax man

[Neal Collins]

Is there any way to avoid paying personal income tax when flipping a house?

Could you hold it for longer than 365 days and only be subject to longterm capital gains tax?

Alternatively, could you fix it up and call it your temporary residence and then buy a place of equal or greater value?

Is there any difference between putting the property in your personal name vs. a business entity's name?

Thanks in advance!
