How the math works

Drift = |current − target|. Trade dollars = Σ|drifts|/2 × portfolio value.

Res 10% + Com 7% + Ind 3% drift = 10% max. (10+7+3)/2 = 10% × $80M = $8M trades required.

Frequently Asked Questions

Why rebalance a real estate portfolio?

Property values grow at different rates. A portfolio started 60% residential / 30% commercial / 10% industrial may drift to 70/20/10 after 5 years if residential appreciates faster. Drift increases concentration risk. Rebalancing back to target means either acquiring underweight assets or selling overweight ones (plus 1031 exchange to defer tax on gains).

Typical threshold bands?

Liquid stock portfolios use 5% bands (±5% off target triggers rebalance). Real estate uses wider 10-20% bands due to transaction cost. Example: 30% target, bands 25-35%, rebalance triggered at 24% or 36%. Bigger bands mean less frequent trades = less transaction cost but more drift. Most sophisticated real estate portfolios rebalance every 24-48 months.

Rebalance mechanics?

(1) Organic: direct new capital to underweight asset class until balance restored. Cheapest, slowest. (2) Selling overweight: realize gains, pay tax or 1031 into underweight. Moderate cost, moderate speed. (3) Refinance overweight: pull equity, deploy to underweight. Keep assets but rebalance economic exposure. Most tax-efficient. (4) Combo approach most common in practice.

When to skip rebalancing?

(1) Small portfolio (<$5M) where transaction cost dominates. (2) Strong conviction that drift reflects rational capital allocation. (3) Tax cost of selling exceeds rebalance benefit. (4) Market-specific cyclicality expected to mean-revert within 1-2 years. Most practitioners: rebalance quarterly on paper, act only on 15%+ drift from targets.
