Revise laws on Montana housing infrastructure revolving loan fund on deed restrictions, usage, and interest

This bill directs the Montana Housing Infrastructure Revolving Loan Fund to keep all interest and income it earns rather than distributing them elsewhere. It also requires that the fund's principal can only be used if approved by a two-thirds vote in both legislative chambers. The legislation authorizes the state treasurer to transfer $50 million from the general fund to the account in 2025 and another $50 million in 2026. Additionally, the law applies retroactively to interest and income earned since June 2023.
