Tax Tips When Planning a Sale
The Federal Statue allows owners of any age who has lived in the property for any 2 year period during the last 5 years to sell capital gains tax exempt for the first $250,000 for single & $500,000 for married couples.  You  may be allowed to do this several times so long as you meet the guide line.   Remember the over 55 once in a life time $125,000 exemption from capital gains on the sale of your principal residence rule has been replaced and no longer applies.  Any tax advise should come from your CPA or accountant who knows your specific financial circumstances.
Have not lived all the 2 years yet?  There is exception to the 2 year rule for job transfers, military orders and other circumstances for which prorations are alowed.  As with all advice on this page you should consult a CPA or Lawyer before you take action.  Your specific circumstances have not been taken into consideration on this page.
Due to the vast information on the Internet regarding taxes, it was clearly important to provide you with a good summary of on-line resources.
