A commercial construction loan is not like a purchase loan. The lender does not hand you the full amount at closing. The money is released in stages, as the work gets done. Each release is called a draw, and the draw process is where construction loans succeed or stall.
Understanding how draws work before you sign the loan documents is one of the highest leverage things a developer or owner builder can do. Most borrower frustration during construction is not about the rate or the terms. It is about a draw that did not arrive when the bills did.
What a draw actually is
A draw is a disbursement of loan funds tied to completed work. Your loan has a total amount, and that amount is divided across the project budget line by line: site work, foundation, framing, roofing, mechanical systems, finishes. When a line item's work is finished, you request the money assigned to it.
This structure protects everyone. The lender never has more money in the project than the completed work is worth. You never pay interest on money that is still sitting undisbursed.
The budget you and the lender agree to at closing is called the schedule of values. Every future draw request is measured against it. Getting this document right at closing matters enormously, because every dollar you can ever draw is limited by what it says.
How a draw request moves through the lender
A typical draw follows the same path on every project. You, or your general contractor, submit a draw request listing the work completed since the last draw. The lender reviews the request against the schedule of values. An inspector visits the site and confirms the work is actually done. The title company updates the title to make sure no new liens have appeared. Then the funds are released.
Each of those steps exists for a reason, and each one can slow the draw down if the paperwork is not clean. The most common delay is a draw request that does not match the inspector's findings. If the request claims the roofing is complete and the inspector finds it half done, the draw gets reduced or held until the work catches up.
Smart borrowers treat the draw request like a discipline. Submit it on a regular cycle. Document everything with photos and invoices. Keep the request consistent with what the inspector will see on site. Lenders process clean requests fast. Messy ones sit.

Inspections are the heartbeat of the loan
Every draw involves an inspection, and the inspector works for the lender, not for you. Their job is to verify that the percentage of completion claimed in the draw request matches reality. They photograph the site, compare progress to the plans, and sign off on the amount the lender can release.
This means the relationship between your contractor's billing and the actual site progress has to stay honest. A contractor who bills ahead of the work will create a mismatch the inspector will catch, and the resulting draw reduction lands on your cash flow, not the contractor's.
Walk the site yourself before every draw request goes in. If you can see that the work is not as far along as the request claims, fix the request before the inspector finds it. The small delay of a corrected request is nothing compared to the delay of a disputed one.
Retainage: the money held back on purpose
Most construction loans hold back a portion of every draw. This is called retainage, and it is released at the end of the project when the work is fully complete. The logic is simple: it gives the lender and the owner leverage to make sure the last details actually get finished.
Retainage catches first time developers off guard because the draws never quite cover the full billed amount. Plan your cash reserves for this from day one, or the final months of the project get tight.
Interest during construction works differently
During the construction phase, you generally pay interest only on the money that has actually been disbursed. Early in the project, when only a few draws have funded, the payment is small. As more draws release, the payment grows. This is one of the genuine advantages of the draw structure: you are not paying for money you have not received yet.
That said, the interest clock runs on the disbursed balance every month, and construction timelines have a way of stretching. Time is quite literally money on a construction loan, which is why schedule discipline matters as much as budget discipline.
Change orders are where budgets go to die
A change order is any change to the plans after the loan closes: different finishes, a moved wall, an upgraded system. Each one changes the cost, and the loan amount does not automatically change with it. Small changes add up fast, and they are the single most common reason projects run out of money before they run out of work.
The lender has to approve significant change orders because they change the collateral the loan is based on. This approval takes time, and draws can pause while it happens. Build a contingency into your budget, and treat every change order as a formal decision with a real cost, not a casual upgrade.
Why draws get delayed, and how to prevent it
Draw delays almost always trace back to a short list of causes. The draw request does not match the site progress. The contractor's invoices are missing or inconsistent. A lien has been filed by a subcontractor who was not paid. The title update shows a problem. Or a change order is sitting unapproved while work continues.
Every one of these is preventable with process. Pay your subcontractors on time so liens never get filed. Keep the draw paperwork complete and consistent. Do not let the request get ahead of the work. And keep the lender informed when something changes instead of letting them discover it from the inspector's report.
When timing pressure is the real problem, short term financing can bridge the gap while a construction loan is being arranged. For that scenario, read: Bridge Loans: When the Deal Cannot Wait for the Bank.
From construction to permanent financing
A construction loan is temporary by design. When the project is complete, the loan has to be resolved, usually by converting to permanent financing or refinancing into a long term loan. This is called the takeout, and it should be planned from the beginning, not discovered at the end.
The permanent loan prices off the finished property: its value, its income, its occupancy. If the project leases up slower than planned or appraises below expectations, the takeout math changes. Start the permanent financing conversation early, with a lender who has reviewed the plans and the pro forma, so the exit is arranged rather than wished for.

The bottom line
The draw process is the operating system of a construction loan. Learn it before you need it: a clean schedule of values, honest draw requests, site walks before every submission, cash reserves for retainage, and a takeout plan from day one. Borrowers who run this process well barely notice it. Borrowers who do not feel every delay in their cash flow. If you are planning a commercial build, tell me the project and the timeline.
