I am a newly admitted Florida attorney. As a favor, I am creating a trust for my best friend's mother. Her goal is to avoid probate and leave her residence to her three adult children in equal shares after she dies. I have two questions. First, will transferring the deed to the trust extinguish her Florida homestead tax exemption? Second, will transferring the deed to the trust ruin the step up basis in the house the kids would get if it was left to them in a will (let's assume she bought the house for $100k, and at the time of her death it is worth $500K)? Any guidance would be appreciated.
