Easy, no work on your part.
The interest, in the form of coupon payments, and your original investment amount flow straight back into your brokerage account. That money will be available for withdrawal, or reinvestment.
If you would like to receive the payments into a different account, you can do so by editing your coupon preferences. You can choose an existing bank account you have linked to your Neighborly account – such as the account you funded your investment with – or connect a new account.
The schedule of interest payments depends on the issuance and investment maturity you choose, so you should always check the terms on the issuance page. For example, some issuances pay interest twice per year, while others, such as zero-coupon bonds, pay returns in one lump sum when the bond matures.
