You won’t owe anything for capital gains. Even if you only paid $100,000 your gain would be $210,000. The exemption limit is $250k for a single person and $500k if married. You are good either way as long as you lived there for 2 years.
but doesn’t the sale still trigger a form to the IRS? They don’t know if it was your primary home or a vacation home, or investment property… I thought you’d still have to go through the paperwork, but end up not owing.
That’s only if it’s your primary home and you lived there a certain number of years in the past 5 years.
Lots of people try to declare their shore houses or investment rental property as their “primary” residence.
