Does OTC lock the permanent rate up front?

Many programs lock the perm rate at closing with optional float-downs. Others lock within a window. Confirm in your term sheet.

How are draws released?

Against a schedule of values with inspections; retainage 5–10% until completion. Photos/invoices speed releases.

What contingency is required?

Commonly 10–15% of hard costs, plus separate interest reserves or verified liquidity.

What are typical leverage limits?

Often up to 80–85% Loan-to-Cost and 70–80% of as-complete value, depending on experience and credit.

One-Time-Close Construction: Builder Math & Milestones

Because two closings is one too many.

For small builders, One-Time-Close Construction (OTC) financing can feel like hitting the turbo boost—just make sure you’re not steering with your knees. It wraps construction and long-term financing into a single loan, a single close, and a lot fewer headaches—if you respect the budget, control the draws, and don’t treat the timeline like a suggestion.

🧠 TL;DR (You’ve Got Lumber to Price, So Here’s the Short Version)

OTC loans combine your construction phase and your end mortgage in one closing. Lock the rate (usually), draw funds as you build, then auto-convert to your permanent loan at completion. No second loan. No second round of underwriting. Just one shot to structure it right—budget tight, timeline realistic, and draw process bulletproof.

🏗️ What Does “One-Time-Close” Actually Mean?

One Closing: One set of docs, one pile of fees, one trip to the notary.
Rate Locked Upfront: Most OTC programs let you lock the permanent rate before you pour a foundation—some offer float-downs just in case rates drop.
Draw-Based Construction: Rehab or new-build funds sit in escrow. Funds release based on a pre-agreed Schedule of Values (SOV) and confirmed progress.

🎯 When OTC Works (And When to Back Away Slowly)

✅ Great fit:

Small builders with clean, shovel-ready SFR or duplex projects
Permits in sight, plans in hand, and buyers/end users lined up
Builders who love spreadsheets as much as siding

⚠️ Risky fit:

Complicated entitlement deals, speculative modern castles, or anything labeled “infill”
GCs juggling too many jobs or missing bonded subcontractors
Projects with a design team that says “What if we…” after you’ve ordered windows

📐 Key Ratios & Guardrails

LTC (Loan-to-Cost): Usually capped at 80–85%, unless you’re flipping blueprints for fun
LTV on As-Complete Value: Often limited to 70–80% of appraised post-construction value
Contingency Budget: Required on many programs—10–15% of hard costs is the norm
Interest Reserve: Pre-escrowed or documented liquidity to cover construction interest

🔢 Worked Example (No smoke, just numbers)

Land (owned): $180,000
Hard + Soft Costs: $520,000
Total Project Cost (TPC): $700,000
As-Complete Appraisal (ACV): $900,000

Let’s test the caps:

85% of TPC: $595,000
75% of ACV: $675,000
→ Lower number wins: $595,000 max loan
→ Equity required: $105,000 + closing costs + contingency (if not baked in)

🧱 Draw Mechanics That Keep You Moving (Not Chasing Inspectors)

Budget → SOV: Break it into chunks—sitework, framing, MEPs, finishes, landscaping, punch-list.
Inspections: Done by third-party or lender’s panel. 48–72 hour turnaround. Paid invoices + photo evidence speed things up.
Retainage: 5–10% withheld until completion of each line item. Final chunk released at CO/punch-out.
Change Orders: Must be pre-approved and funded (via contingency or your own cash). No “oops” allowed.

📋 Milestone Draw Template (Copy/Paste Ready)

Permits, sitework, utilities rough-in (10–15%)
Foundation/slab, vertical framing (20–25%)
Roof/windows/doors “dried-in” (10–15%)
Rough MEPs + inspections (10–15%)
Insulation, drywall, prime coat (10%)
Cabinetry, fixtures, finishes (10–15%)
Exterior, landscaping, flatwork (5–10%)
Punch-list + final retainage (5%)

No fluff. No mystery milestones. No check released for “vibe improvements.”

🔁 What Happens at the End

Once you get the Certificate of Occupancy and final inspection clears, your construction loan automatically converts into the permanent loan you locked upfront—fixed, ARM, interest-only, whatever was agreed.
Any float-down terms, escrow setup, and prepayment penalties? Those should be clear before you break ground.

🗂️ Docs That Make Underwriters Say “Yes” Instead of “Hmm…”

Stamped plans, permit status, and geotech if needed
Full budget, detailed SOV, and a timeline (Gantt-lite will do)
GC license + insurance, subcontractor list, and backup bids
Appraisal showing “as-complete” value, with comps that match your spec
Builder’s risk insurance + general liability, and proof of interest reserve

🚩 Common Red Flags (and How to Fix Them Before They Kill Your Deal)

Too-thin contingency: Raise it to 10–15%, or show a backup liquidity source
Unrealistic timelines: Build in buffer for weather, subs, inspections, and whatever the city dreams up
Permit mysteries: Sort out utilities, encroachments, and demo approvals before close
GC risk: Weak resume? No bonded trades? Fix it or expect pricing to reflect the doubt

🧠 Is OTC Worth It for Small Builders?

Yes—if you’re disciplined with your build plan and want to avoid two closings, two sets of fees, and the joy of re-qualifying mid-project.

No—if your permits are stuck in limbo, your design is still “evolving,” or you need to push leverage beyond comfort.

Best move: Price it out against the classic two-step (construction loan → take-out). Then pick the structure that protects cash flow, timeline, and sanity.
