What this preset is for

BTR GDV is NOI / net initial yield. Op-cost ratio 25 to 30 percent of gross rent; yield 4.25 to 5.5 percent.

Yield-based GDV

  • BTR GDV = NOI / net initial yield. Op-cost ratio 25 to 30 percent of gross rent.
  • London Z1-Z3 NIY: 4.25 to 4.75 percent. Manchester: 4.75 to 5.25 percent. Birmingham: 5.0 to 5.5 percent.

Profit-on-cost

  • BTR PoC typically lower than build-for-sale (15 to 18 percent vs 20+).
  • Lower target return justified by certainty of forward-funded exit and yield compression.
