What an OTC construction loan actually is

A one-time close construction loan is a single mortgage that covers two phases of your project. Phase one is the construction period — typically eleven months — during which the lender funds the build in scheduled draws. Phase two is the permanent mortgage that takes over the day construction is complete. Both phases are closed at the same settlement table, the same day, on the same note.

That single-closing structure is the whole point. With a traditional two-close construction loan, you sign once for the construction note, then again months later for the permanent loan — and you re-underwrite, re-appraise, and re-pay closing costs the second time. An OTC skips that second round entirely.

Who OTC is built for

• Land owners who have held a parcel for a year or two and are ready to build.
• First-time builders who want one lender, one loan officer, and one rate strategy from lot to move-in.
• Families trading up who plan to sell their current home once the new one is finished — bridge-plus-construction in one file.
• Rural and semi-rural buyers in counties where the conventional path (buy lot, build, refinance) adds months of friction.

Rate lock before you break ground

The single biggest structural advantage of an OTC is that you lock your permanent rate before the first concrete is poured. A two-close borrower is exposed to whatever the bond market does during the eleven months of construction. An OTC borrower isn't. Ask about our extended-lock options on your scenario call — rates move with the market, so we don't publish numbers that would be stale by the time you read them. Call for current rates.

The eleven-month construction period

Most OTC programs give you eleven months from first draw to certificate of occupancy. That window covers permitting lag, weather delays, and the usual surprise with subcontractors. If your builder needs longer, extensions are available on a case-by-case basis.

During construction, you pay interest-only on the amount drawn. You are not making principal-plus-interest payments on money the builder hasn't spent yet. When the final draw funds and the house is complete, the loan "modifies" to its permanent amortizing structure — same note, same lender, no new closing.

How the draw schedule works

Construction money doesn't land in your account in one lump. It releases in stages, each one tied to a physical milestone. A typical schedule looks like:

1. Closing draw. Lot payoff or refinance, plans, permits, soft costs.
2. Foundation. Site work, excavation, footings, slab or basement.
3. Framing + dry-in. Roof on, windows in, exterior sheathed.
4. Mechanicals. Rough plumbing, HVAC, and electrical inspected.
5. Interior finish. Drywall, cabinets, flooring, paint.
6. Final. Trim, fixtures, final inspection, certificate of occupancy.

Your builder requests each draw, an inspector verifies the work in place, and the funds release to the builder. No advances. No funny money. Every dollar is tied to work already completed.

Modification to permanent: the day the loan "flips"

When the last draw funds and the CO is issued, the loan automatically converts to its permanent terms. You start making principal-and-interest payments the following month. There is no second closing, no second set of title fees, no second appraisal. The note you signed at the beginning is the note you pay off at the end.

What you will need to qualify

OTC borrower guidelines are close to conventional, with two added layers: the builder must be approved, and the project itself has to appraise. We cover the full checklist in our OTC Requirements post, but at a high level you are looking at:

• Credit and income underwriting, same as a conventional purchase.
• Builder approval — we walk them through it.
• Land either owned outright or included in the loan.
• A signed fixed-price contract with your builder.
• A contingency fund to cover overruns.
• An appraisal supporting the completed value.

Why OTC beats the traditional "lot loan + construction + refi" stack

Many builders still recommend the three-step approach: buy the lot with a lot loan, take a short-term construction loan, then refinance into a permanent mortgage. Every one of those steps is a separate closing with separate costs. Every one is a separate underwrite. Every one is a chance for your rate to move against you. An OTC collapses the stack into a single file. One closing, one set of fees, one rate decision, one relationship.

Colorado-specific notes

Jon Howard is licensed in Colorado. If your lot is in Larimer, Weld, El Paso, Douglas, Jefferson, or any other Colorado county, we can underwrite it. Mountain lots and rural parcels add a few wrinkles — private well, septic, access easements — but none that disqualify the loan. Our Larimer market report and El Paso market report walk through the county-by-county specifics.

Your OTC file, step by step

1. Scenario call. Fifteen minutes. Lot, build budget, credit band, timeline.
2. Builder vetting. We review the builder's license, insurance, and project history.
3. Pre-approval. Written conditional approval with program, LTV, and estimated closing costs.
4. Plans and contract. Final plans and a signed fixed-price contract.
5. Appraisal. As-completed value based on plans and comps.
6. Closing. One table, one note, construction begins.
7. Draws. Monthly, tied to milestones.
8. Modification. Permanent phase begins the day the CO is issued.

Next step

The fastest way to know if OTC fits your project is a scenario call. Bring the lot address (or the address you are targeting), an approximate build budget, and a builder name if you have one. We will tell you which program fits, what your draws would look like, and what it takes to close in the current market.
