关于avoiding capital gain tax, 这里说：

Keep in mind a few rules for this special exclusion: 

• It only applies to a home if it is your primary residence. It doesn’t apply to rental properties. 

• You must have lived in the home for at least two of the past five years. However, you don’t need to have lived in the home for two consecutive years. 

• You can only take advantage of this exclusion once every two years.

另外问了chatgpt, 说是ira contribution 也能抵税。如果是，我可以用这个抵掉一些，毕竟房子便宜。
