Core concepts

Discounted basis

Office trading at 30–50% of replacement cost in many CBDs.

Conversion math

Floorplate, window-line, plumbing dictate feasibility.

Examples

  • $30M downtown office bought for $9M; converted to 120 lofts.

Practical applications

  • Urban markets with office distress.
  • Tax-credit-stacking sophistication.

Common mistakes

  • Assuming all office is convertible.
  • Underestimating MEP rebuild costs.
