The Canadian Last Will and Testament will work in the USA. But it will involve a court proceeding in Arizona in the local Probate Courts in order for the heirs to take title to the property. (Translation: time, aggravation, money.) Better to consider using some sort of simple holding structure. The idea for this is not to achieve any particular tax savings because they won't, probably, be designed for that. They're designed to do one thing and one thing only -- when the owner dies, the heirs inherit the asset quickly and without court proceedings.
Ideas we use: trusts, limited liability companies, life estates.
I do this stuff all day every day, so yes I am a lawyer but this is not legal advice and you're not my client, etc. etc. Insert standard disclaimer, waiver, pre-emptive strike, warning shot here.
