I got married in mid-2017 and both my husband and I owned houses that we are getting ready to sell. We will probably both sell them in 2018. We each lived in our individual houses all of the last 5 years (except for 1year), so individually we meet the ownership and residency requirement. I've read that we can each claim up to 250k capital gains deduction when we sell. Do we need to file separately to do so, or are we able to claim both houses on a joint return? If we have to file separately, would there be any issue with filing jointly for our 2017 taxes and then filing separately on our 2018 taxes? Can we switch filing strategies?
