Rent vs Buy: A Stress Test Perspective

Buying builds equity. Renting preserves flexibility. Stress testing shows which one survives pressure better.

Test Buying Scenarios

The missing variable: downside risk

Most rent vs buy calculators assume everything goes according to plan. Stress testing asks: what happens when it doesn’t?

Why renting can be safer (sometimes)

  • Lower fixed commitments
  • Faster exit in income disruption
  • No repair or escrow shock

Why buying can still win

  • Strong margin and savings buffer
  • Stable income
  • Long time horizon

How to compare properly

  1. Stress test the mortgage side.
  2. Look at runway under job loss or expense spikes.
  3. Compare flexibility, not just cost.

Use the tool to see whether buying survives stress better than renting for your situation.
