Of all the types of investments Henry could have chosen, he decided to try real estate because, according to Henry, "as everyone knows, real estate never goes down". Yea, right. Last year he bought an apartment house in Camden, N.J. (Of all the places ...) Paid $400,000. One year later he decided to sell - for $360,000. OK during the year he did collect rent of $12,000 (assume no other income or expenses). Given this data, what was the rate of return on this dog of an investment?
