We bought a house and moved in 2015, then sold our prior home in 2016. Does the 2016 sale get entered as a sale of main home, or sale of second home.

[Coleen3 · Accepted solution]

The house sold in 2016 was your primary home from the time you bought it (assuming it was) until the time you moved out in 2015. You would have to meet the two out of five year rules ending with the date of sale in 2016.
