The Nelsons purchased a new residence in 1992 for $300600 from David who owned and used the residence as rental property. When the Nelsons wanted to purchase the property it was being rented to tenants who had four months remaining on their lease. The Nelsons paid the tenants $1000 to relinquish the lease and vacate the property. In 1996 they added a family room to the house at a cost of $79200. In 1998 they suffered had damage to the roof and received $7000 from the insurance company. They did not repair the damaged roof, and no casualty loss deduction was allowed. What is their adjusted basis for the house today?
