My husband and I got married in 2015. We both owned houses and lived in them as our primary residence through 2016. (I had lived in mine for 9 years and he had lived in his for 4 years since purchasing). In 2017, we rented my house and moved into his house as our primary residence. We want to sell both houses and upgrade to a different house this year. We meet ownership and residence requirements, individually for both houses. If we sell both in the same year, will that impinge on the look back requirement? Could we still qualify for the gain exclusion if we change our filing status to married, filing separately?
