What Is New Construction Financing and How Does It Work?

New construction financing is short-term, stage-based funding used to build a structure from the ground up, where the lender releases money in installments called "draws" as verified building milestones are completed rather than handing over the full amount at closing. Because there is no finished building to appraise or collateralize on day one, the loan is underwritten against the project's plans, budget, timeline, and the borrower's capacity to deliver. Interest is typically charged only on the money actually drawn, and most of these loans are designed to be repaid or refinanced within 12 to 24 months once the project is complete. For the contractors and builders who execute the work, the real cash-flow problem is rarely the construction loan itself, it is covering payroll, materials, and mobilization in the gap between draws, which is where revenue-based working capital becomes the practical companion tool.

How new construction financing actually works, step by step

Unlike a mortgage on an existing property, a construction loan is a draw-against-progress instrument. The mechanics run in a predictable sequence:

1. Underwriting the plan, not the building. The lender reviews architectural plans, a line-item construction budget, the general contractor's track record, permits, and the projected as-completed value. Approval rests on whether the numbers and the timeline are credible.
2. Closing and the initial draw. At closing the borrower usually contributes equity (land or cash) first. The lender then funds an opening draw for mobilization, permits, and site work.
3. Milestone draws. Money is released in tranches tied to completed phases, foundation, framing, dry-in, mechanicals, finishes. Each draw request is verified, often by a third-party inspector, before funds move.
4. Interest-only during the build. You typically pay interest only on the balance drawn to date, which keeps early carrying costs lower while the project is producing no income.
5. Completion and conversion. Once the structure passes final inspection and receives a certificate of occupancy, the loan is repaid from a sale or converted into permanent, longer-term financing.

The core idea to internalize: the lender's risk drops every time a milestone is verified, so their willingness to release cash is directly tied to demonstrated progress, not promises.

The building blocks: draws, interest reserves, and retainage

Three mechanisms shape the cash flow of almost every new construction loan, and misunderstanding them is where builders get squeezed.

The draw schedule is the master document. It maps each release of funds to a specific, inspectable stage of completion. If your schedule says framing pays out at 40 percent completion, you finance framing yourself until an inspector confirms you hit it. That lag is real and it is where operating cash gets thin.

The interest reserve is a pool the lender may set aside from the loan proceeds to cover interest payments during construction, since the project generates no revenue yet. It is convenient but it is not free money, it reduces the funds available for actual building and it can run dry if the timeline slips.

Retainage is a percentage (commonly around 5 to 10 percent) that the owner or lender holds back from each payment until the job is fully complete and signed off. It protects against defects and abandonment, but for a subcontractor or GC it means a meaningful slice of every invoice is deferred to the very end.

Together these three features mean that even a fully approved, well-run project routinely operates with a working-capital gap. Learn more in our complete guide to business financing.

Types of new construction financing

"New construction financing" is an umbrella. The right structure depends on who is building and what happens at completion.

• Construction-to-permanent (single-close). One loan funds the build and then automatically rolls into a long-term mortgage. One closing, one set of costs, popular for owner-occupied and build-to-hold projects.
• Stand-alone construction loan (two-close). Covers only the build; you arrange separate permanent financing or a sale at the end. More flexibility, but you close, and pay closing costs, twice.
• Commercial construction loan. For ground-up commercial or multifamily projects, underwritten heavily on projected income and the sponsor's experience.
• Owner-builder / spec construction. For builders constructing without a committed buyer. Higher scrutiny and larger equity requirements because the exit is a future sale.
• Renovation and hard-money bridge loans. Faster, asset-based, shorter, and more expensive, used by investors who need speed over cost.

None of these products, however, is built to solve day-to-day operating cash flow for the contractor doing the work. That is a separate financing lane covered below.

Example project: how draws and the cash-flow gap look in practice

The table below is an illustrative, for-example draw structure on a ground-up build. Figures are round numbers to show the mechanics, not a quote, and no lender guarantees any specific schedule.

Read the right-hand column carefully. In every phase, the builder spends first and gets reimbursed after verification. On a busy shop running several jobs at once, those overlapping gaps are exactly what strains payroll and vendor terms, even when every project is profitable on paper.

Decision framework: when new construction financing fits, and when to reach for working capital instead

Use the tool that matches the job. A construction loan and revenue-based working capital solve different problems.

A traditional new construction loan works best when:

• You are financing the actual cost of building a specific, permitted structure.
• You have the equity, plans, and a completion or sale exit that a lender can underwrite.
• Your timeline allows weeks of underwriting and third-party inspection cycles.
• You want interest-only carry during the build and the lowest cost of capital.

Avoid leaning on the construction loan, and consider revenue-based working capital, when:

• The gap you need to close is operating cash, payroll, materials deposits, mobilization, not the build budget itself.
• You are waiting on a draw or on retainage and need to bridge days, not months.
• Your credit is thin or your FICO sits in the 500s, but your bank deposits show consistent revenue.
• You need funds in 24 to 48 hours, not after a full construction-loan underwrite.
• You are a subcontractor or GC who never touches the construction loan directly but still has to fund the work.

The two are complementary. The construction loan builds the building; working capital keeps your crew paid and your suppliers current in the space between draws.

The recommended path for contractors: revenue-based working capital

For the builders, GCs, and subs who actually execute new construction, the fastest and most accessible funding is not another real-estate loan, it is revenue-based financing sourced through a marketplace of funders. Here is why it fits the trade:

• Approval on deposits and revenue, not credit. Underwriting looks at your business bank statements and cash flow. Because it weighs revenue over credit score, owners with a FICO of 500+ can still qualify.
• Speed that matches a job site. Decisions and funding commonly land in 24 to 48 hours, fast enough to cover a payroll run or a materials order while you wait on a draw.
• Sized for real projects. Funding typically starts around $10,000 and scales with your monthly revenue.
• Repaid from cash flow. Repayment flexes with your receipts rather than demanding a fixed lump-sum event, which suits the lumpy, milestone-driven cash flow of construction.
• A marketplace, not a single lender. Applying once puts your file in front of multiple funders, improving the odds of a workable offer.

Nothing here is ever guaranteed, offers depend on your actual bank activity and business profile. But for closing the gap between what you spend and when you get paid, revenue-based working capital is the practical tool. See how it stacks up in our business financing guide.

Qualifying and applying: what to have ready

Whether you pursue a formal construction loan or revenue-based working capital, preparation shortens the timeline.

For a construction loan, expect to provide complete architectural plans, a detailed line-item budget, permits or proof they are in process, your contractor's license and track record, proof of equity or land ownership, and personal and business financials. Underwriting is document-heavy and slow by design.

For revenue-based working capital, the lift is far lighter, typically the last several months of business bank statements, a basic application, and proof of ownership. Because approval keys on deposit history and revenue, a lower credit score is not disqualifying, and the whole cycle can close in a day or two.

A practical move for active builders: line up a working-capital source before you need it, so a slow draw or delayed retainage never forces you to miss payroll or lose a supplier discount.
