When you first enter the residential rental property in program as a rental property, you go through several screens to describe the property you are adding as rental, the cost of the rental property, the date acquired and the date the property became available as a rental. See screenshot
One of the following screens asks about the Land Value and the Value of the Improvements. This includes the rental property as an Asset. See screenshot
So when the Rental Asset is sold the program gives you the original entries made for both the cost of the property and the the land value, as shown in my screenshot Sale_of_Rental_3.jpg
