How do I make assumptions for the exit cap and discount rate in the following question using the screenshot below?

"Estimate each propertys current value by calculating the present discounted value of expected future cash flows given to you in Exhibit 11 (Screenshot Below). To complete your valuation, you will need to make an exit cap and discount rate assumption."

Please include work, calculations, and reasoning. Thank you!
