Savings Bonds
If you have Savings Bonds, they are a financial asset, too. Since you hold the actual bonds in your possession, the easiest and best way to verify them for your mortgage lender is to make photocopies of them. If you choose to cash them in for down payment or closing costs, you should do this at your local bank. Be sure to keep copies of the paperwork the bank provides because that will establish the current value of the bonds and show that you received their cash value.
