|---|---|---|
| Interest Rate | Annual percentage charged on the principal. | 3%–7% for qualified borrowers |
| APR | Includes interest plus fees and insurance. | 3.5%–8% depending on lender |
| Loan Term | Length of repayment, usually 36–72 months. | 36–72 months |
| Origination Fee | One‑time charge for processing the loan. | 0%–3% of loan amount |
