The most common surprise on a first construction or renovation loan is this: the money doesn’t arrive up front. A $500,000 construction loan doesn’t land $500,000 in your account at closing. Instead, the lender pays you back in stages as the work gets done — you (or your general contractor) pay for a phase of work, then request reimbursement, and the lender releases that slice of the loan after checking the work is real.
Those slices are called draws. Understanding how they work — and the timing gap they create — is the difference between a project that runs smoothly and one that stalls because you ran out of cash waiting to be reimbursed. The mechanics protect both sides: money tracks actual progress instead of promises. But they also mean you need working capital to float the gap between spending and getting paid back.
Draws, not a lump sum
A construction loan funds against completed work, not against your signature. The lender approves a total budget — say $500,000 — and breaks it into a draw schedule tied to milestones: site prep and demo, framing, mechanical systems, finishes, and completion. As each milestone is finished, you request the draw that covers it.
This is the opposite of a permanent mortgage, where the full amount funds at closing. Here the loan releases in pieces, and you don’t get the next piece until the last one is verifiably done. The upside for you: you’re not paying interest on money you haven’t used yet (more on that below). The catch: you have to pay first and collect second.
The draw process, step by step
- Draw request — you submit a request for the completed phase, with invoices, receipts, and a schedule of values showing what percent of each line item is done.
- Inspection / verification — the lender sends an inspector (or reviews photos and a title update) to confirm the work is actually in place and matches the request. No verified work, no release.
- Lien waivers — subs and suppliers sign waivers confirming they’ve been paid for the work in that draw, so no one can later file a lien against the property.
- Funds released — the lender releases the draw, usually minus retainage (a held-back slice), and the loan balance you owe interest on goes up by that amount.
The mechanics that catch owners off guard
Retainage. Lenders typically hold back roughly 5–10% of each draw and don’t release it until the whole project is complete and final-inspected. It’s a completion incentive — it makes sure the last, least glamorous 10% of the work actually gets finished. Plan for it: you won’t see that money until the end.
Interest only on what you’ve drawn. You’re charged interest on the funds actually released, not the full loan amount, so early months cost little and later months cost more as the balance climbs. Many construction loans build in an interest reserve — a pool inside the loan that covers interest payments during the build, so you’re not paying out of pocket while the project has no income yet.
The float. Because you pay contractors before the draw reimburses you, and because retainage stays behind, you need working capital to bridge the gap. Underestimating that float is the single most common way a well-funded project runs short of cash mid-build.
A $500,000 renovation, released in draws
Illustrative only — real draw schedules vary by lender, project, and how line items are grouped. But the shape is real: money follows finished work, retainage waits until the end, and you carry the gap in between.
| Total renovation budget | $500,000the full loan amount |
|---|---|
| Draw 1 — demo & framing | $120,000less ~7% retainage held → ~$111,600 released |
| Draw 2 — systems (mechanical, electrical, plumbing) | $150,000less retainage → ~$139,500 released |
| Draw 3 — finishes | $180,000less retainage → ~$167,400 released |
| Draw 4 — completion | $50,000final phase, less retainage → ~$46,500 released |
| Retainage released at completion | ~$35,000~7% held across all draws, paid after final inspection |
Notice two things. First, you pay each contractor before the draw reimburses you, and each release comes up short by the retainage — so at any given moment you’re out of pocket for work already done plus the ~$35,000 held back to the end. That’s the float you must carry: budget for it in cash, not just in the loan. Second, because interest is charged only on funds drawn, your early payments are small and grow as the balance builds — the interest reserve, if you have one, is what keeps those payments from hitting your bank account mid-build.
What owners expect vs. how draws actually work
What owners expect
- The full loan lands in my account at closing.
- I pay interest on the whole amount from day one.
- I get every dollar of the budget as I go.
- Once the loan closes, cash flow is handled.
How draws actually work
- Money releases in stages, after each phase is finished and verified.
- Interest is charged only on funds actually drawn, so it starts small and grows.
- The lender holds back retainage on each draw until final completion.
- You pay first and get reimbursed second — you need working capital to float the gap.
Common questions
- Do I get the construction loan money up front?
- No. A construction loan reimburses completed work in stages called draws. You (or your contractor) pay for a phase of the work, submit a draw request, and the lender releases that portion after verifying the work is done. The full amount is never deposited at closing the way a permanent mortgage is.
- What is retainage?
- Retainage is a portion of each draw — typically 5–10% — that the lender holds back and doesn’t release until the entire project is complete and passes final inspection. It’s a completion incentive that makes sure the last details of the job actually get finished. Plan for it in your cash budget, because you won’t see that money until the end.
- When do I start paying interest on a construction loan?
- You pay interest only on the funds that have actually been drawn, not on the full loan amount. So interest is small in the early months and grows as more draws are released and the balance climbs. Many construction loans include an interest reserve — money set aside inside the loan to cover those interest payments during the build, before the property produces income.
- What is a draw inspection?
- Before releasing a draw, the lender verifies that the work you’re requesting payment for is actually in place. That usually means an inspector visits the site, or reviews dated photos and a title update, and confirms the completed work matches your draw request. If the work isn’t verifiably done, the draw isn’t released.
- What are lien waivers and why does the lender want them?
- A lien waiver is a signed document from a subcontractor or supplier confirming they’ve been paid for the work covered by a draw. Lenders require them so that no one who worked on the project can later file a lien against the property claiming they weren’t paid. Missing or incomplete waivers can hold up your next draw.
- What happens if a draw gets delayed?
- A draw can stall if paperwork is incomplete, an inspection hasn’t cleared, or lien waivers are missing — and in the meantime you’ve already paid contractors for that work. That’s why the timing gap matters: a delayed draw doesn’t pause your bills. Keeping draw requests clean, documented, and submitted early is the best way to keep releases on schedule.
- Do I need working capital on top of the construction loan?
- Yes. Because you pay for each phase before the draw reimburses you, and because retainage is held back until completion, you’re always out of pocket for work already done. You need cash reserves to float that gap. Underestimating the float is the most common reason a fully financed project runs short of cash mid-build.
