Doesnt matter, no second best. Rebalance = Sell the winner to buy the loser.

There is no point to money of you never intend to spend it... If you have no property, buying some is a lower time preference decision than continuing to rent something forever. Allowing you and your future kin to stack more in the future.
Yes that i dont disagree with. But buying a property to live in isn't the same as buying up properties as investment. A rebalance implies putting it into a different investment vehicle to gain future wealth
There is no second best. Buy corn, practice low time preference and use corn to buy things that meaningfully improve your life and will last generations.
