Explanation:
6 month free concession in first year drops rent to:
= 20 / 2
= $10
Effective rent = [Present value of Year 1 rent + Present value of Year 2 rent + Present value of Year 3 rent ] / [ 1 - (1 / (1 + rate)^ number of years) / rate]
= [(10 / (1 + 10%) ) + (21 / (1 + 10%)²) + (22 / (1 + 10%)³)] * [1 - (1 / (1 + 10%)³/ 10%)]
= (9.09 + 17.355 + 16.5289) / 2.48685
= $17.28
