Ann, who died in January 2012, was survived by her husband, Jack. Ann and Jack were married in 1996. Ann's federal gross estate was equal to $6,000,000 on the date of her death. When Ann died, Ann's assets included an undeveloped parcel of real estate in Jacksonville in the names of "Ann and Jack, as joint tenants with right of survivorship." The fair market value of the land on the date of Ann's death was $750,000. Jack provided all of the consideration for the purchase of the land, paying $200,000 for it in 2000. Alternate valuation is not available to Ann's estate as all assets owned by Ann will pass, either under Ann's last will and testament or by operation of law, to Jack. What is Jack's basis in the real estate after Ann's death?
