Remember also that the interest on the loan is taxed at ordinary income rates.So for example lets say you have 100k and were making 8% in the markets - 8k per year and say you are in top bracket, you will pay $1600 in taxes per year or netting 6400.Now lets say you did a loan and were at 5% you are earning $5k per year (actually less because principal is being paid down and some of money goes into essentially a 0% checking account).
