Genevieve bought a condo in Colorado for her personal use in 2018. She paid $250,000 at the time of sale. After a good-faith effort, it was determined that none of the cost was allocable to the land. In 2021, she replaced the furnace and air conditioning system for a total cost of $10,000. In 2022, she converted the property to a rental property. At the time of the conversion, the fair market value of the property was $300,000. What is the basis for depreciation of the condo?
