Raising money by mortgages and borrowing the money directly from financial institutions. The presence of debt financing provides financial leverage, which tends to magnify the effects of increased operating profits on the individual and corporation's returns. Interest is tax deductible. Further, leverage is desirable as long as the borrowed funds produce a return in excess of their cost. However, to much debt can result in higher levels of financial risk in meeting the principal and satisfying interest payments. Excessive debt will make it more difficult to raise funds and will increase further borrowing costs.
