when your happy that washinton d.c. is gaining stuff

Answer 2

Say you buy something for $1000.

Over time it gets more valuable, so say now it's worth $1200.  You would say it has appreciated by $200.  You don't have any capital gains yet because it's still yours.

NOW, say you sell it for $1200.  Your capital gain is $200.

In other words, appreciation = how much more is it worth than when you bought it?

Capital gain = how much more than what you paid for it did you sell it for?
