I have a primary home in Maryland to sell next year with aproximately 500k equity and a second property ( rental) in PA that I must sell. I am married and retired. I believe I can claim residence at the second property while having work done on primary since we would live at the rental most of each year for two years prior to selling. If the two properties are sold within months of each other, is there a time limit on how soon the two properties can be sold in order to avoid capital gains on the rental? ( or as I understand, a portion of gain on the rental)
