Get a construction loan that converts — a construction-to-permanent, or "one-time close," loan — when you have a signed fixed-price contract, permits in hand or clearly pending, a qualified builder, and a permanent repayment source (stabilized property income or predictable business cash flow) you can document. That combination is the trigger. The right moment is before you break ground but after your budget, timeline, and take-out are all real on paper — because a converting loan locks your permanent terms up front and saves you a second closing, but it also freezes those terms months before the building is finished. If any leg of that stool is still soft — the scope keeps changing, the tenant is not signed, the numbers only work on a spreadsheet — you are too early, and locking now costs you flexibility you will want later.
The rest of this guide gives you a decision framework for that timing, walks through the cash-flow test most owners skip, and covers what to do when your build is ready but the bank's underwriting calendar (30-60 days on a good file) is not — including a faster revenue-based path for the working-capital gaps a construction loan was never built to cover.
Key takeaways
- Get a construction-to-permanent loan when five things are true at once: signed fixed-price contract, permits in hand or pending, equity ready, a documented take-out, and a budget contingency.
- A converting loan locks permanent terms up front — its advantage is one closing and cost certainty; its trade-off is committing to those terms months before the building exists.
- Bank construction underwriting typically runs 30-60 days on a clean file, which often does not match a contractor who is ready to start now.
- The step most owners skip is stress-testing cash flow: interest-only draw payments plus normal operating costs through the full build, with a buffer for a 30-60 day overrun.
- A revenue-based advance from an MCA marketplace complements — not replaces — a construction loan, covering deposits, soft costs, and the working-capital gap during underwriting.
- Revenue-based advances are approved on bank deposits and revenue rather than credit-first, consider FICO 500+, start around $10,000, and decide in roughly 24-48 hours.
- No construction or converting loan is ever guaranteed; conversion depends on the project meeting agreed conditions, so keep contingency and cash-flow buffers in place.
What a "loan that converts" actually is
A construction loan that converts is one financing instrument that funds the build and then rolls into permanent financing without a second closing. During construction you draw funds in stages against completed work and typically pay interest only on the outstanding balance. When the project hits completion and passes inspection, the loan converts — the same note becomes a fully amortizing term loan (or permanent mortgage) at terms set at the original closing.
Two structures dominate:
- Construction-to-permanent (one-time close): You close once, at the start. Your permanent rate and term are locked or floated with a fixed conversion date. One set of closing costs, one underwriting event.
- Construction-only, then refinance: Two separate loans and two closings. More flexible on the back end, but you re-qualify — and re-pay closing costs — when the build is done, exposing you to rate movement and any dip in your financials during construction.
The converting version wins on cost and certainty. Its trade-off is commitment: you are agreeing to permanent terms today for a building that will not exist for six to twelve months. That is why when you pull the trigger matters as much as whether you qualify.
The signal to get one: five things that must be true
Do not apply because rates look good this week. Apply when the project itself tells you it is ready. All five of these should be true before you submit:
- Signed, fixed-price contract with a real builder. Cost-plus and open-ended scopes make lenders nervous and make your budget a guess. A GMP (guaranteed maximum price) or fixed-price contract is the cleanest signal.
- Permits in hand or clearly in the pipeline. Entitlement risk is the fastest way to blow a timeline. Lenders want to see the path to permits, not a hope.
- Equity/down payment ready. Most construction lenders want you in for 15-25% of total project cost, and they usually want your equity spent first, before their money draws.
- A documented take-out. This is the permanent repayment source: a signed lease or LOI for the space, stabilized rent projections, or business cash flow that clearly services the converted payment. No credible take-out, no conversion worth locking.
- Contingency in the budget. A 5-15% contingency line is not padding — its absence signals to an underwriter that you have not built before.
When four of five are solid and one is still moving, you are close but early. Locking permanent terms around a variable is how owners end up refinancing out of a loan that was supposed to be permanent.
The decision framework: should you get one now, wait, or bridge?
Run your situation through these four gates in order. The first one you fail tells you your move.
Gate 1 — Scope certainty. Is the contract fixed-price and the design final? No → Wait. Finalize scope first; a converting loan is the wrong tool for a moving target.
Gate 2 — Take-out certainty. Can you document the permanent repayment source (lease, stabilized income, or cash flow)? No → Wait or pursue construction-only, so you are not locking permanent terms against an unsigned tenant.
Gate 3 — Cash-flow carry. Can your business absorb interest-only draw payments plus its normal operating costs through the entire build, with a buffer for overruns? No → Fix the working-capital gap before you break ground (see the next section).
Gate 4 — Timeline fit. Does the lender's 30-60 day underwriting window fit your groundbreaking date? No → Bridge the gap with faster capital, then let the construction loan take over on its own schedule.
Pass all four and the answer is clear: get the converting loan now, while your file is at its strongest. Fail one and the framework has just saved you from locking the wrong terms at the wrong time.
Timing scenarios (illustrative)
| Scenario (for example) | Scope | Take-out | Cash-flow carry | Best move |
|---|---|---|---|---|
| Owner-user building a new shop, lease-to-self, 6-mo build | Fixed-price, permits pending | Own business occupies it | Comfortable | Get the converting loan now |
| Spec build, tenant not yet signed | Fixed-price | Unsigned LOI only | Comfortable | Wait or go construction-only |
| Restaurant expansion, contractor ready Monday | Fixed-price, permits in hand | Documented cash flow | Tight during build | Bridge working capital, then convert |
| Design still changing, GC not chosen | Open scope | Vague | Unknown | Too early — finalize first |
Figures and scenarios above are illustrative examples, not quotes or guarantees.
The cash-flow test most owners skip
A converting loan is underwritten on the project. Your business still has to run while the project is being built — and that is where owners get caught. During construction you are typically paying interest on a growing balance as draws release, while the new space produces zero revenue. If your existing operation is already running lean, those interest-only payments plus a single change order can tip a healthy business into a cash crunch three months before the building opens.
Before you break ground, pressure-test the build against your actual deposits, not your best month:
- Can your current revenue cover normal operating costs and the rising draw interest through the full timeline?
- What happens to cash flow if the build runs 30-60 days long — the norm, not the exception?
- Is there a buffer for the overrun the contingency line does not cover?
If the honest answer is "it would be tight," the problem is not your construction loan — it is a working-capital gap sitting underneath it. Solve that first, with capital built for cash flow, and let the construction loan do the one job it is good at: funding the build.
When the build is ready but the bank calendar is not
The most common timing failure is not disqualification — it is speed. Your contractor can start Monday, your equity is ready, the scope is locked, but bank construction underwriting runs 30-60 days on a clean file and longer when appraisals, environmental checks, or draw schedules get involved. Miss the contractor's window and you can lose your slot, your pricing, or your season.
This is exactly the gap a revenue-based advance from an MCA marketplace is built to close. Instead of underwriting the project, this financing underwrites your bank deposits and revenue — approval is driven by cash flow, not primarily by credit score. Typical parameters look like this:
- Approval on business bank deposits and revenue rather than credit-first underwriting
- FICO 500+ considered — revenue carries more weight than the score
- Funding amounts starting around $10,000
- Decisions in roughly 24-48 hours, with funds behind the decision
It is not a replacement for the construction loan. It is the tool that keeps the project moving in the days the construction loan cannot: covering deposits to lock a contractor, bridging the soft costs before the first draw releases, or carrying operating cash flow through the build so the interest-only period does not starve the rest of the business. When the converting loan closes and begins drawing, the advance has already done its job. To weigh it against other short-term options, see our pillar guide to business funding options for small businesses.
Getting one vs. skipping the conversion
Sometimes the smarter timing move is not to lock permanent terms at all. Choose the converting structure when certainty is worth more to you than flexibility — the scope is fixed, the take-out is signed, and you would rather pay one set of closing costs and know your permanent payment today. That is the owner-user building for their own business, or the developer with a pre-leased project.
Skip the conversion — go construction-only and refinance later — when the back end is genuinely uncertain: the tenant is not signed, you expect your financials to strengthen during the build (which could earn you better permanent terms later), or you may sell or recapitalize on completion. You pay for that flexibility with a second closing and exposure to rate movement, but you are not married to terms set around assumptions that had not come true yet.
And when neither the build nor the take-out is ready but you need capital now for a time-sensitive opportunity — a deposit, an equipment slot, a supplier discount — a revenue-based advance stands on its own, independent of the construction timeline entirely. Match the instrument to where your certainty actually is, not to which product has the lowest headline rate.
How to get the timing right — a short playbook
Put the framework into motion with these steps:
- Lock scope and price first. Get to a fixed-price or GMP contract before you talk to a construction lender. Everything downstream depends on it.
- Document your take-out early. Signed lease, LOI, or a clean cash-flow projection. This is what makes the "permanent" half of the loan real.
- Stress-test cash flow against real deposits. Run the interest-only carry plus operations plus a 30-60 day overrun. Find the gap before the lender does.
- Solve the working-capital gap before you break ground. If the carry is tight, line up revenue-based capital now — approval on deposits, funding from ~$10,000, decisions in about 24-48 hours — so the build never stalls on cash.
- Apply to the construction lender when your file is strongest. All five signals true, contingency built in, timeline mapped to the underwriting window.
- Reconcile the two timelines. Use fast capital to hold the contractor and cover soft costs during the 30-60 day underwriting gap, then hand the build off to the construction loan as draws release.
Get those steps in order and the converting loan does its one job cleanly, on a project that was ready for it. For the full menu of short- and long-term tools, keep our business funding options guide handy.
Frequently asked questions
When is the right time to get a construction loan that converts?
When five things are true at once: a signed fixed-price contract, permits in hand or clearly pending, your equity ready, a documented permanent repayment source (take-out), and a contingency in the budget. That is the moment to lock — before you break ground but after the budget, timeline, and take-out are all real. If any of those is still moving, you are early, and locking permanent terms around a variable usually leads to refinancing out of a loan that was meant to be permanent.
What's the difference between a construction-to-permanent loan and construction-only?
Construction-to-permanent (one-time close) closes once, funds the build, then converts to a permanent term loan automatically at terms locked up front — one closing, one set of costs, more certainty. Construction-only is a separate loan you refinance into permanent financing later — two closings, but more flexibility if your back end is uncertain. Choose converting when certainty beats flexibility; choose construction-only when the take-out is not yet signed or your financials should improve during the build.
Can I qualify with a low credit score or tight cash flow during construction?
Bank construction loans lean heavily on the project, your equity, and your credit. If your credit is thin or cash flow is tight during the build, the gap is often best solved separately with a revenue-based advance, which is approved on your bank deposits and revenue rather than credit-first, considers FICO around 500 and up, and starts near $10,000. It funds the working-capital gap under the construction loan rather than replacing it.
How long does construction loan approval take, and what if my builder is ready sooner?
A clean construction-loan file typically underwrites in about 30-60 days, longer with appraisal, environmental, or complex draw schedules. If your contractor can start before that, a revenue-based advance with decisions in roughly 24-48 hours can bridge the gap — covering deposits and soft costs to hold your slot — then hand the build off to the construction loan once draws begin.
Should I get the converting loan or just refinance after the build?
Get the converting loan when scope is fixed and the take-out is signed and you want one closing and known permanent terms today. Skip the conversion and refinance later when the tenant is not signed, you expect your financials to strengthen during the build, or you may sell or recapitalize on completion. You pay for that flexibility with a second closing and rate exposure, but you are not locked into terms built on assumptions that had not come true.
How much cash flow do I need to carry a construction loan?
Enough to cover your normal operating costs plus rising interest-only draw payments through the entire build, with a buffer for a 30-60 day overrun and overruns the contingency line does not catch. Pressure-test this against your real deposits, not your best month. If it would be tight, the issue is a working-capital gap under the loan — solve that first with cash-flow-based capital before you break ground.
What can a revenue-based advance be used for around a construction project?
For the gaps a construction loan was not built to cover: deposits to lock a contractor before underwriting finishes, soft costs before the first draw releases, and operating cash flow through the build so the interest-only period does not starve the rest of the business. It is underwritten on deposits and revenue, funds from about $10,000, and decides in roughly 24-48 hours. It complements the construction loan rather than replacing it.
Is a construction-to-permanent loan guaranteed once I start?
No financing is guaranteed. Converting loans usually set the permanent terms at the initial closing and convert on completion and inspection, but conversion still depends on the project meeting the agreed conditions. Treat the numbers you are quoted as terms, not a certainty, and keep a contingency and a working-capital buffer so a delay or overrun does not derail the conversion.
