My sister and I own two separate houses jointly. The one house is deeded between her and I with a fmv of 700K orig purchased 20 years ago for 370 ) with depreciation an adj cost basis of 120K and mortgage balance of 530K . The other house is deeded between her and my husband valued at about 400K with a mtg balance of 225 and basis of 250K . Purchased in July 2006. Although fair market values are unequal our equity in both houses is equal at approx. 170 K each. We want to gift each other our share so that we will both own one house outrightly.. I will own w my husband the downtown house for 700K she will own the uptown house for 400K.. What are the tax ramifications of such a move should I sell my downtown home in two years after making it my primary residence with my husband for two years. Thank you
