With Prop 19, this will trigger a re-evaluation of the property unless my husband makes the property his primary residence.

If the property has already transferred to three siblings, the act of a buy out will trigger reassessment on 2/3 of the property.If the property is still in trust and has not yet been distributed, there may be more options.

If you close in your name and transfer the deed after it is a SALE this can trigger the lender to call the loan, you can't get insurance to match the note and they check.

I would suggest that you look into whether holding title as joint tenants will trigger the change in ownership needed to effect pre-Prop 19 benefits.

My understanding is, that a parent to child tfr or grandparent to grandchildren tfr (only if all parents of those grandchildren are deceased), or inheritance from parent, may not trigger a reassessment as long as the child/grandchild is using the property as their primary residence. 

You’re talking fix and flip investments.What triggered your concern?  

But, when one is serious and can pull the trigger it makes the journey getting there TOTALLY WORTH IT! 

The plan is to have several months of expenses set aside for the initial ramp-upI do like your idea of having everything lined up and to be ready to pull the trigger on things as soon as the license is active! 

The main fear is having a Canada revenue agency loss, this can trigger a "Why is your property losing money" survey.

Not ready to pull the trigger to start building.
