I regret splitting my taxable account into US and international instead of simplifying with VT, but it's too late to change now. So now it's become a hassle to rebalance and potentially in the future I may not even be able to as the divergence can grow too big.
Anyways how close should the percentages be to avoid going too far off target? For example let's say I want 62% US and 38% international. What would be an acceptable range before needing to rebalance? I assume 63%/37% would still be pretty close, what about 65%/35%, what about 70%/30%? Where is the limit exactly?
