Appreciation sensitivity (20% down)

Delta at year 30
Buying beats “left in the market” only if appreciation ≥ 4.2%/yr. You’ve set 2.0%.
Appreciation / yrDelta at year 30
0.0%-$2,112,564

5.0%+$711,087
6.0%+$1,919,404

Holding revenue, rate, and costs fixed. The market baseline grows at 7%/yr — appreciation has to overcome that gap.

The mortgage never enters your portfolio — it goes to the seller. From here, the market pot grows at your market return (± the rental’s yearly cash flow) and equity grows with appreciation + principal paydown.
