Bond

A note that a government or corporation gives an investor, which promises to repay the borrowed amount plus interest on a specific date

Bonds help finance large, expensive projects, such as building new bridges or highways. When you buy a bond, the seller agrees to repay the bond principal to you when it matures, and to make interest payments.

The longer the bond takes to mature, the higher the interest payments since there is more risk at stake. If you are looking to raise money for a down payment, you might want to consider investing in short-term bonds since they have a low risk factor.
