A live-in gut that kept a valid CO through the whole job, where the utility nearly cost the schedule.
Here is a live-in flip worth writing up as a case, because the sequencing is the whole lesson. House is a 1,650 square foot 1940s two-story in a first-ring suburb, bought at 218k, worst house on a decent street. The owner runs a small crew and acts as their own GC, which mostly means the work happens in the gaps between paying jobs and the dining room disappears for a long time. Spend is 84k in materials and subbed trades over 25 months. The owner's own labor and the crew's overtime are not in that number, and priced at what a contractor bills, add maybe 55k. Sold at 402k, selling costs 24k. The thing done right is sequencing around living there. The house never loses a functioning bathroom or a functioning kitchen for more than nine days, because the second bath gets done before the first is touched, and a temporary kitchen goes into the dining room with a rental fridge and an induction burner before a single cabinet comes out. Permits go in phased, one trade at a time, so there is always a house that is legal to occupy. That matters more than people think over two years with a family in the building, and permit and owner-builder rules vary by state, so one owner's experience will not be another's. What nearly breaks it: the service upgrade to 200 amp. The utility takes eleven weeks from application to meter set, against the four weeks budgeted, and everything downstream (drywall, inspections, finishes) stacks up behind it. Some 14k of ordered materials sits in the garage the whole time. What to keep: phase the permits, and apply for anything involving a utility the day of closing. What would you cut from that sequence if you only had one bathroom to start with?
