On every fix & flip pro forma, add 30 days to your renovation timeline estimate.
Not because you're pessimistic. Because you're a professional.
Here's why 30 days matters in actual dollars:
At 10.25% on a $250,000 average bridge balance:
30 extra days = $2,135 in carry cost
That $2,135 is either:
(A) A buffer you modeled — which means your deal still works at the real margin
(B) A surprise you didn't model — which means your deal underperforms
Why projects run over:
→ Permit delays: 2-6 weeks is common in most markets
→ Material lead times: 1-4 weeks on cabinets, windows, HVAC equipment
→ GC resequencing: 1-3 weeks when subcontractors have scheduling conflicts
→ Listing prep and photography: adds 5-10 days after renovation completes
Total realistic variance: 3-8 weeks across a typical mid-level project.
The buffer doesn't cost you anything if the project finishes on time.
It protects you from the 38% of projects that don't.
