You can model selling your primary home in the future. This is the best option if you plan to rent. State tax modeling will update to your new state at the time of the sale.
On My Plan > Home & Real Estate, open the "Future changes to primary residence" section
Select "Sell/Rent" when asked what type of change you would like to model
Enter the age that "You" will be at the time of relocation
Select the account to fund the sale proceeds or down payment
Enter the estimated rent for your new residence in today's dollars
Enter the state of your new residence
Make sure to add a one-time expense in My Plan > Expenses for taxes you'll need to pay as a result of the sale of your primary residence
