Acting as your own general contractor on a flip means you're the one hiring and scheduling every subcontractor, pulling permits, and making the daily calls a GC normally makes — in exchange for not paying a GC's markup, typically a meaningful percentage of the total project cost depending on the market and the contractor. That savings is real, but it only shows up if you can actually do the job well; done poorly, self-GCing tends to cost more in delays, mistakes, and rework than the markup you were trying to avoid.
What You're Actually Taking On
- Scheduling and sequencing — coordinating multiple trades so plumbing rough-in happens before drywall, electrical is inspected before it's covered, and no one shows up to a site that isn't ready for their part of the work.
- Sourcing and vetting subcontractors yourself — without a GC's existing relationships, you're finding, vetting, and building trust with electricians, plumbers, and other trades from scratch, which takes time and carries more risk of a bad hire.
- Permits and inspections — knowing what your local jurisdiction requires, when, and managing the inspection process directly rather than having a GC who already knows the local building department's quirks.
- Quality control — catching subpar work before it's covered up by the next trade, which requires enough hands-on knowledge to know what good work actually looks like.
- Liability — as the person coordinating the job, you're more exposed if something goes wrong on site. Talk to an insurance agent about what coverage you need in this role versus hiring a licensed GC who carries their own.
Questions Worth Answering Honestly Before You Decide
- Do you actually know what a fair bid looks like for each trade? Without that knowledge, you can't tell if a subcontractor's quote is reasonable or a red flag, which is exactly the judgment a GC would normally bring.
- Do you have the time to be reachable and present during the project? Self-GCing generally requires being available for site visits, decisions, and problem-solving throughout the workday, not just checking in after hours.
- Do you understand your local permitting process? Or are you willing to learn it before, not during, your first self-GC'd project?
- Can you handle a subcontractor no-show or a mid-project dispute without a GC's relationship leverage or experience to fall back on?
- Is this your first flip, or have you already been through a few with a GC managing the process? Many experienced flippers who self-GC did so after first learning the process by working closely alongside a hired GC on earlier projects.
When Self-GCing Tends to Make Sense
- You have real construction, trades, or project management background — not just DIY enthusiasm.
- You have the time to be genuinely present and responsive throughout the project, not squeezing it in around a full-time job.
- The project scope is more cosmetic than structural, reducing the complexity of coordination and the cost of a mistake.
- You already have working relationships with reliable subcontractors from past projects.
When Hiring a GC Tends to Make More Sense
- This is your first flip, or your first flip in this specific market where you don't have existing trade relationships.
- The project involves significant structural, electrical, or plumbing work where mistakes are expensive and hard to reverse.
- You can't be on-site or reachable regularly during working hours.
- Your timeline is tight enough that scheduling missteps from inexperience would be genuinely costly.
A Middle Ground Worth Considering
You don't have to choose all-or-nothing. Some flippers hire a GC for the complex, high-risk phases (structural, electrical, plumbing, permitting) and self-manage the more straightforward cosmetic phases (painting, flooring, fixtures) where the cost of a mistake is lower and the coordination is simpler. This hybrid approach captures some savings without taking on full liability and scheduling responsibility for the entire project.
Common Mistakes
- Underestimating the time commitment — self-GCing is close to a part-time job during active construction, not an occasional check-in.
- Skipping or misunderstanding permits to save time, which can create expensive problems at resale if unpermitted work is discovered.
- Hiring subcontractors based on price alone without checking references or past work.
- Not carrying adequate insurance for the increased liability of coordinating the job yourself.
- Taking on a structurally complex project as a first self-GC attempt instead of starting with something more forgiving.
Frequently Asked Questions
Q: How much money does self-GCing actually save?
A: It varies by market and project size — GC markups are typically a percentage of total project cost, but the number differs enough by region and contractor that you should get a real GC quote for comparison rather than assuming a fixed savings figure.
Q: Do I need a contractor's license to be my own GC on my own property?
A: Requirements vary by state and by whether you're doing the licensed trade work yourself (electrical, plumbing) versus hiring licensed subcontractors for those parts. Check with your local licensing board before assuming you're covered either way.
Q: What's the biggest risk of self-GCing that people don't expect?
A: Scheduling breakdowns — one trade running late cascades into every subsequent trade's schedule, and without a GC's established relationships and leverage, resolving those conflicts falls entirely on you.
Q: Should a total beginner ever self-GC a flip?
A: It's possible but risky — most people who self-GC successfully have some prior construction or project management background, or built that knowledge by working closely with a hired GC on an earlier project first.
