can you add a few details to the situation?
did these two homes have different street addresses? which did you and your spouse declare as your "home address" in 2015 and 2016? which address did you sleep in at night? did you change where you slept in 2017?
were the homes titled differently?
is one really a primary residence and the other a 'second residence'? Only the primary residence gets the benefit of the $500,000 exclusion.
I am interested in what others have to say...... I just have the questions...
