"Going Rate" (Interest Rates and Costs)

As of April 2026, the referendum is under consideration and specific interest rates for a potential new issuance have not been locked in, as they depend on market conditions at the time of sale.

Preliminary Estimates: A $500, 000 home might see a tax increase of roughly $65 per month, or $777 per year, depending on final interest rates, project scope, and timing.


Historical Context: In September 2023, the Board approved 20-year term bonds, with rates locked in at the time of sale. This current referendum might entail a 30-year term.
