@Llewelyn A. Regarding the CD, why is the average return($25,967/30k)over the 10 years 8.66% but the interest rate paid is 6.43%? If you were to take the annual interest payment every year and not leave it in the CD to compound, you would be receiving $1,930 every year for 10 years, which is a 6.43% return. When the money is left in the CD to compound, your average return is greater that the quoted rate.
If we are not going to touch the annual payment from the CD, but rather leave the money in the CD to compound, wouldn't we need to do the same with the annual cash flow from the property? Somehow reinvest the cash flow into another investment?
If I understand the whole concept of your post, you are just trying to compare different investment products based upon the total you have invested, the total you collected at the end of year 10 and what that rate of return is. Each product will have very different variables and investment features, so you are trying to match up the total money received at year 10?
