LightStream home improvement loans are actually secured loans, rather than unsecured. When you apply for a loan with LightStream, they require that you use your home equity or the financed property as collateral for the loan. This means that if you fail to repay the loan, they have the right to repossess your property to cover their losses. However, since these loans are backed by collateral, they often come with lower interest rates and more flexible terms compared to unsecured loans.
