One of the first questions a new flipper asks when they apply for a rehab loan is simple: do I have to hire a licensed general contractor, or can I run the job myself? The answer drives your budget, your draw process, and sometimes whether the deal gets approved at all. This guide walks through how fix and flip lenders actually treat the contractor question in 2026, when you can act as your own general contractor, and what it costs you either way.
Why lenders care who is doing the work
A fix and flip loan is underwritten against a future value. The lender is advancing money today against the after repair value the property should hit once the rehab is finished. That number only comes true if the work gets done, gets done to code, and gets done on the timeline the loan was built around. So the lender has a direct financial stake in whether the crew swinging the hammers can actually deliver.
That is the real reason the contractor question comes up. It is not bureaucracy. The lender is protecting the collateral. A verified, experienced crew lowers the odds that a 150,000 dollar purchase with a 60,000 dollar rehab budget stalls out half-finished, which is the scenario that turns a performing loan into a workout file.
Do you legally need a licensed general contractor?
There are two separate questions here and investors constantly blur them. The first is what your state and municipality legally require. The second is what your lender requires. They are not the same thing.
On the legal side, most states let a property owner pull permits and act as their own general contractor on a property they own, within limits. Some trades, electrical, plumbing, and gas work in particular, almost always require a licensed sub regardless of who is running the overall job. If you are doing structural changes, additions, or anything touching the building envelope, expect the permit office to want licensed trades on the technical work. Always confirm with the local code office before you assume you can self perform, because the rules vary block by block, not just state by state.
On the lender side, the policy is usually risk based rather than a flat yes or no. A lighter cosmetic rehab on a borrower with a track record often gets approved with the borrower acting as their own general contractor. A heavy or structural rehab, a first time flipper, or a large loan tends to trigger a requirement for a licensed general contractor on file, with a signed contract and a scope of work.
When you can be your own general contractor
Self performing the general contractor role, meaning you manage the subs, order materials, and control the schedule yourself, is most commonly allowed when several things line up: the rehab is cosmetic to moderate rather than structural, you have completed flips before, the loan is modest, and your rehab scope of work is detailed and realistic. If your underwriting file shows two or three finished projects and clean payoff history, most lenders will let you run a straightforward cosmetic job.
Acting as your own general contractor saves real money. A general contractor typically marks up the job 10 to 20 percent to cover their overhead and profit. On a 60,000 dollar rehab, that markup is 6,000 to 12,000 dollars that stays in your pocket if you self perform competently. On a thin flip, that spread is the difference between a good month and a wasted quarter.
The catch is that self performing eats your time and exposes you to the schedule risk the general contractor would normally carry. If your day job or your next acquisition needs your attention, the money you saved on markup can evaporate in extra holding costs when the job runs long.
When a licensed general contractor is required
Expect the lender to require a licensed general contractor when the rehab is structural, when you are adding square footage, when the loan is large, or when you have little or no flip history. In those cases the lender wants a signed construction contract, the general contractor’s license and insurance on file, and a fixed scope tied to the draw schedule.
The requirement is not just a signature. The lender will often verify the license is active, confirm the contractor carries liability and workers compensation coverage, and in some cases run a lien and litigation check on the contractor. A general contractor with a stack of open mechanics liens is a red flag, because those liens can jump ahead of the lender’s position on title.
How the contractor choice runs through your numbers
Walk a simple deal. Purchase price 150,000 dollars, rehab budget 60,000 dollars, after repair value 280,000 dollars. Say the lender funds 90 percent of purchase and 100 percent of rehab, so you bring 15,000 dollars down plus closing costs, and the loan draws the 60,000 dollars of rehab in stages as the work passes inspection.
If you hire a general contractor at a 15 percent markup, your true rehab cost is closer to 69,000 dollars once the markup is baked in, but the loan still only advances against the approved 60,000 dollar budget. That extra 9,000 dollars either comes out of your pocket or has to be negotiated into the original budget the lender approved. Investors who skip this math get surprised at the closing table when the funded rehab does not cover the contractor’s real invoice.
If you self perform and hit the 60,000 dollar budget, your spread on the deal improves by that markup, but you carry the risk that a missed subcontractor or a failed inspection pushes your timeline and your interest cost. Either way, run the deal both ways in the deal calculator before you commit, and keep a contingency reserve so a cost overrun does not force a hard-money bridge to finish.
Documenting the contractor for approval
Whether you self perform or hire out, the paperwork the lender wants is similar. Have a line item rehab budget that matches the scope of work. If you use a general contractor, add the signed contract, the license number, and proof of insurance. If you self perform, be ready to name the licensed subs handling electrical, plumbing, and mechanical, and to show you have done this before. A clean, specific package moves approval faster and protects your profit margin by keeping the loan structured around real numbers.
Lien waivers and paying the crew
Whoever does the work, the way you pay them protects your loan and your title. Lenders want to see that subcontractors and suppliers are paid as draws are released, because an unpaid sub can file a mechanics lien against the property, and that lien can take priority over parts of your loan. The tool that manages this is the lien waiver: a signed release from each sub or supplier confirming they have been paid for the work covered by a given draw.
On a general contractor job, the contractor usually collects waivers from the subs and passes them up with each draw request. When you self perform, that collection job is yours. Get a conditional waiver when you schedule a payment and an unconditional waiver once the sub has actually been paid, and keep the paper. This matters at the exit as much as during the rehab. When you go to sell, a clean title with no open liens is what lets the closing fund on time. A single forgotten waiver from a plumber can hold up a sale and cost you weeks of extra carry, which is a self inflicted wound that has nothing to do with the quality of the renovation.
The habit that keeps you safe is simple: never release your own money or request a draw without a matching waiver, and reconcile your budget against paid invoices every draw cycle. It is unglamorous, but it is the difference between a clean flip and a title mess.
Bottom line
You do not always need a licensed general contractor for a fix and flip loan, but the deal, your experience, and local code decide it, not your preference. Light cosmetic jobs from an experienced flipper often clear with self performing. Structural work, big loans, and first timers should plan on a licensed general contractor with a signed contract. Get the contractor question answered before you write the offer, because it changes both your budget and your approval odds.
