A permit sat 111 days and took my profit from 41k to 6k
This one's finished and closed, so I can give the whole number.
1,380 sq ft bungalow, bought at 118 with hard money. Scope was a real gut: full rewire, all new supply and waste, HVAC where there'd been baseboard, new kitchen, two baths, and we were moving a wall to open the kitchen to the living room. That last item is the one that mattered.
Budget 132. ARV 310 based on four comps between 298 and 322. Modeled 120 days of carry at about 3,900 a month, so 15,600. Expected profit around 41k after selling costs. Not fat, workable.
The wall was load bearing. We knew that. Plan was a flush beam, engineer's letter, structural permit. I'd been told by two people locally that structural review in that jurisdiction ran three to four weeks.
It ran 111 days. Not because anything was wrong with the drawings. The plans examiner position was vacant for six weeks and then the backlog cleared in the order it arrived. I called every week. I escalated twice. There's no version of this where calling more would have helped.
Meanwhile: I couldn't close walls anywhere in the house because the structural work hadn't been inspected, so the electrical and plumbing rough stayed exposed and my GC pulled his crew to another job in week five, which is exactly what I'd have done in his position. When the permit came through I waited another three weeks to get him back.
Final: 251 days from purchase to closing. Carry came in at 32,900 against 15,600 modeled. Two extensions on the note at a point each, 4,700. Construction went 9k over, which is honestly fine for a gut. Sold at 307.
Profit was 6,100 on 132k of my own money at risk for eight months.
What I'd do differently, plainly. I'd sequence the structural permit application before closing, as a contingency, or at minimum file it the day I close rather than at week three when the demo revealed what I already knew was there. I'd have asked the building department directly what their current review queue looked like instead of asking two contractors what it used to be. And I'd have written the GC contract with a re-mobilization commitment and a date, because losing the crew was what turned a permit delay into a schedule collapse.
The thing I'd say to anyone modeling 90 days: the permit isn't a task on your timeline. It's a gate, and everything behind it stops.
