Yes that should be done automatically for you. Make sure to select Rental income from the dropdown menu for Select an income source when you add or edit the INCOME. Leave the End date blank. When you click submit, it’ll then ask you for the property to link the income to (it should have been previously entered in REAL ESTATE). Also make sure the property and the income have the same Owner (ie if you have a spouse and the income is joint, the property should also be joint owner). Click Submit again once you selected the property from the drop-down.
The INCOME Type should now be listed as RENTAL. The income will stop when the property is sold in the TIME MACHINE.
