You might invest in an asset that will return after-tax cash flow to you of $2,700 per month for 15 months (first cash flow one month from now), and after receiving the last cash flow youll immediately receive after-tax net proceeds from liquidation equal to $95,600 . You make an offer to buy the asset so that youll get your target annual rate of return of 18.20% (compounded monthly). The seller makes a counteroffer that is $9,600 higher than your offer. Find your annual rate of return if you buy at the counteroffer price and receive the expected cash flows.
