Question

Some friends are urging you to chip in with them to buy a vacant parcel og land on the outskirts of your city. A one-fourth interest would cost you $10,000.Total annual expenses on the property are $2,200.When the property is sold,assume that you'll have to pay a real estate commission of 10% of the selling price and that the income taxes on any profit will be 15% of the profit.If the property is sold after 3 yrs,how much will it have to sell for so that you can reap an average annual net return of 10% of your $10,000?HELP PLEASE!
