Several years ago, shortly after their marriage, Ian and Jenny purchased for $2,000,000 beachfront land held for speculative investment, title to which they took as joint tenants with rights of survivorship. Ian died last year and the land was appraised at $8,000,000 for inheritance and estate tax purposes. Jenny sold the land this year, and her amount realized was $7,800,000. How much gain or loss has Jenny realized and recognized?
