Assuming that the average market rate for tax-exempt municipal bonds is five percent, the following would apply.
When an applicant with a service area population of twenty-five thousand or less can demonstrate that its sewer user rates for the proposed project are between three and five percent of the MHI, the applicant may be eligible for a twenty-year repayment term and a one percent interest rate. This interest rate represents twenty percent of the average market rate for tax-exempt municipal bonds (see figure 2).
| Sewer User Fee divided by MHI | Below two percent | Two percent and above, but Below three percent | Three percent and above, but Below five percent | Five percent and above |
| Hardship Designation | Nonhardship (Low sewer user rates in relation to MHI) (Not funded with grant or forgivable principal dollars) |
Moderate Hardship | Elevated Hardship | Severe Hardship (Very high sewer user rates in relation to MHI) |
| Loan Hardship-Funding Continuum | Loan at sixty percent of market rate | Loan at forty percent of market rate | Loan at twenty percent of market rate | Loan at zero percent interest |
