Investment projection · LEGO Ideas tier

Is LEGO Tree House a good investment?

Based on the lego ideas tier historical appreciation rate of 14.3% annually (from the HSE 2022 LEGO investment study + BrickEconomy theme data), a $450 sealed LEGO Tree House could be worth:

In 5 years
$878
1.95× your $450 starting value
In 10 years
$1,713
3.81× your $450 starting value
In 20 years
$6,518
14.49× your $450 starting value

Projections assume the set stays sealed. Opening typically removes 30–50% of resale value. Past performance doesn't guarantee future returns — supply, demand, and condition all matter.
