Capital Gains on improved property

[David Green]

I purchased a condo several years ago and pumped quite a bit of money into it to improve the property.  I later moved out and rented the place out.  It has been rented now for more than 3 years. So I can't qualify for the 250K/500K exclusion.  

I was wondering if sell, do I have to pay capital gains on the difference between my original purchase price and the selling price?  Am I able to deduct any of the improvements I made from that gain?

Thanks
