Generally revise tenant landlord laws

This bill updates Montana's residential landlord-tenant laws to modernize how security deposits are handled and to allow for electronic communication and payments. It directly affects landlords and tenants by changing rules for cleaning charges, damage deductions, and the return of security deposits. Key provisions include allowing landlords to deduct reasonable cleaning labor costs, requiring written notice before charging for cleaning, and permitting landlords to send notices and refund deposits via email or electronic transfer. The bill also clarifies that landlords remain liable for returning deposits even if tenants fail to provide a new address, and it allows for immediate implementation upon passage.
