with financial advisors and underwriters, issues the debt to fund school construction, expansion, and infrastructure repairs. (WASBO.com)

"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.
