Most investors who've done a few rehabs have a contractor story. A deposit handed over, then a crew that showed up two days a week. Work that had to be torn out and redone. A contractor who stopped answering after demo.
The usual reaction is to go find a better contractor. Sometimes that's the answer. But the same contractor can do good work on one job and poor work on the next, and the pattern repeats often enough that it's worth looking at the structure, not only the people.
It's usually a structure problem
A contractor's attention follows their cash flow. Whether your job gets their best crew this week depends on:
- How many other jobs they're running
- Their cash position this month
- Whether they've already been paid for your job
- Whether anyone is checking progress week to week
A large deposit changes the incentives on the day you sign. The money is in the contractor's account before any work is done. If they have four other jobs, the one that already paid is the easiest one to push back. Milestone payments help a little, but milestones are weeks apart, and whether one is "done" is often a judgment call.
Any contractor who needs 30–50% up front before starting may be using that money to fund other jobs. At best, your deposit buys materials for your project. At worst, it covers payroll somewhere else.
The real cost of a bad contractor: a worked example
The deposit is only the first loss. Here's a hypothetical flip, with every number labeled as an assumption, to show how the costs stack up.
The deal. A $52,000 rehab, planned for 10 weeks. The contractor takes a 30% deposit: $15,600. After three weeks of slow, partial work worth about $8,000, they stop showing up.
Direct loss. $15,600 paid, $8,000 of work in place: $7,600 gone.
Recovery. A new contractor has to assess someone else's half-finished work, and picking up a stalled job usually costs more than starting fresh. Assume the remaining scope comes in $6,000 over the original price, plus $4,000 to redo work that wasn't right: $10,000.
Time. Three weeks lost to the first contractor, a few weeks finding and mobilizing a new one, and a week of rework. Assume the project runs 5 weeks longer at $800 a week in holding costs (loan interest, insurance, utilities, taxes): $4,000.
| Cost | Example amount |
|---|---|
| Net lost deposit | $7,600 |
| Replacement premium and rework | $10,000 |
| Extra holding costs | $4,000 |
| Total | $21,600 |
That's before the opportunity cost. Your capital sits in this deal for weeks longer than planned instead of funding the next acquisition. On a thin-margin flip, a total like this can take most of the profit. For more on how slow weeks add up, see holding costs and slow contractors. If you're already in this spot, here's what to do when a contractor disappears after a deposit.
Early warning signs
Most blown jobs give signals well before the contractor disappears:
- The crew is on site fewer days than the schedule assumed
- You learn about progress only when you drive by
- Questions about the timeline get vague answers
- Requests for more money arrive before the work they're supposed to cover
- Scope changes show up on an invoice instead of in a conversation
Any one of these is worth a written question the same week you notice it.
What actually limits the damage
Most of the table above comes from two things: too much money paid before work was done, and problems found in week three instead of week one.
Pay as the work happens. With weekly labor draws, the full project price is quoted up front, and you pay a set amount each week while work is in progress, credited toward that total. There's no large check before the job starts, so what you've paid stays close to the work you've seen done. How weekly labor draws work, with a side-by-side example against a 40% deposit.
See progress every week. A weekly update with photos and progress against the timeline shows a slow start in the first week, while it's still cheap to fix. See what a useful weekly rehab progress report includes.
Write the scope first. A detailed scope of work tells you what each week should deliver. It's also what a replacement contractor would need to pick up the job without starting the assessment from scratch.
Keep materials separate. When you buy materials yourself at cost, the payments to your contractor are labor only, and a deposit can't quietly fund someone else's job.
What this doesn't fix
A payment structure doesn't turn a bad contractor into a good one, and it doesn't lower the project price. You still need to vet the contractor, check license and insurance, and write the scope. What the right structure does is make a bad fit show up early, when it costs a week, not a whole deal.
How we work
Seller's Little Helpers is a licensed and insured general contractor that works only with real estate investors in Chicagoland, and our crews handle every trade. We quote the full project price up front. Weekly labor draws are sized to each project's contract, scope, schedule and labor requirements, with a $4,000 weekly minimum; the first draw reserves your start date, and every draw is credited toward your total. You buy materials at cost from our material lists. Mason sends a weekly update with photos, progress against the timeline, draw and budget status, and any decisions that need your sign-off, and scope changes are discussed with you before any work is done.
