Establish the Montana family legacy home act

This bill, titled "Montana Family Legacy Home Act" (SB 500), clarifies administrative rules for selling Montana state-owned cabin and home site properties, directly affecting current lessees of these properties. It reduces the required deposit (bid bond) for prospective buyers from 20% to 5% of the sale price and allows current lessees to cancel a sale with 10 days' notice (unless another bid is placed), while requiring lessees to pay upfront for sale preparation costs (like appraisals or surveys). If the lessee doesn’t buy the property, they get their costs refunded; if someone else buys it, the new owner pays the actual costs at closing. The bill also exempts cabin/home site sales from standard environmental review requirements and makes the state cover survey costs upfront.
