The Nelsons purchased a new residence in 2005 for $300,000 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 $1,000 to relinquish the lease and vacate the property. In 2009, they added a family room to the house at a cost of $79,200. In 2011, they suffered hail damage to the roof and received $7,000 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?
