Is an Equity Sharing Agreement a loan?

No. There's no interest rate, no monthly payment, and no debt added to your credit profile. Unison invests in your home and shares in its future change in value. Your only payment is based on the home's final market value due when you sell, buy out the agreement, or reach the end of the 30-year term. If you sell after the restriction period and your home has lost value, you could owe less than the amount you received up front. In cases of significant depreciation, Unison's final payment could even drop to zero.
