Building a custom home means juggling two financial events at once: paying to build the house and financing the mortgage that will eventually cover it. A construction-to-permanent loan folds both into one product, but the mechanics, draw schedules, interest-only phases, appraisal timing, and the eventual conversion to a fixed-rate mortgage, trip up even well-prepared buyers. This guide walks through the construction-to-permanent loan process stage by stage, from pre-qualification to the single closing that turns your build into a permanent mortgage. Before you start, you should have a chosen builder, a rough project budget, and a sense of your target loan amount relative to the 2026 conforming limit of $806,500, since that number affects which programs are even on the table.
Step 1: Decide If a Construction-to-Permanent Loan Fits Your Build
A construction-to-permanent loan, often called a single-close loan, combines your construction financing and your long-term mortgage into one loan with one closing. You close once, before the first shovel hits dirt, and the loan automatically converts to a permanent mortgage once the home is finished. A two-time-close construction loan, by contrast, requires you to close on a short-term construction loan first, then refinance into a separate permanent mortgage once the build is done, which means paying closing costs twice and requalifying a second time under whatever rates and underwriting standards exist at that later date.
The single-close structure fits buyers who already have finalized architectural plans, a licensed and vetted builder under contract, and a realistic construction timeline, typically nine to twelve months from groundbreaking to certificate of occupancy. If your plans are still fluid or you haven’t selected a builder, you’re not ready to apply yet; underwriting for this program depends heavily on a fixed scope of work and a firm contract price.
One misconception worth correcting early: a construction-to-permanent loan is not the same product as a renovation loan like a 203k. A 203k finances improvements to an existing structure you’re purchasing or already own. A construction-to-permanent loan finances a home built from the ground up on land you own or are purchasing as part of the transaction. The underwriting, draw processes, and inspection requirements differ enough that treating them interchangeably will slow down your application.
Step 2: Get Pre-Qualified and Vet Your Builder
Before you commit to a lot, a floor plan, or a builder contract, it helps to know what you can actually qualify for. Duane Buziak’s NoTouch Credit Pull lets you pre-qualify and compare construction-to-permanent program fit, conventional, VA, jumbo, or Non-QM, without a hard inquiry landing on your credit report. That matters here more than in a typical purchase, because you may be comparing multiple program structures and don’t want each comparison dinging your score before you’ve even chosen a build path.
Builder vetting happens in parallel with your own pre-qualification, and it’s not optional. Programs generally require that your builder be licensed, carry adequate liability insurance, and in many cases be pre-approved by the broker before the loan can move forward. This isn’t a formality: the builder’s financial stability and track record directly affect the broker’s risk on a loan that will fund in stages over the better part of a year. If your builder hasn’t worked with construction-to-permanent financing before, expect an extra step where the broker collects references, licensing documentation, and proof of insurance.
Once you’re pre-qualified and your builder is vetted, bring a signed construction contract with a detailed, line-item cost breakdown, not just a verbal estimate or a rough number on a napkin. Underwriters need to see costs broken out by category: site work, foundation, framing, mechanicals, finishes, and contingency. A vague total slows underwriting because the broker has to go back to the builder for clarification, and that back-and-forth can add a week or more to your timeline before you’ve even locked a rate.
Step 3: Structure the Draw Schedule and Rate Lock
Funds on a construction-to-permanent loan don’t disburse all at once. They release in stages, called draws, tied to specific construction milestones and verified by inspections. A typical draw schedule ties payments to foundation completion, framing, drywall, and final completion, though some programs break these into more granular stages depending on the size and complexity of the build. Each draw request triggers a site visit before money moves, which protects both you and the broker from paying for work that hasn’t actually happened.
During the construction phase, you make interest-only payments, and it’s worth being precise about how those are calculated: interest accrues only on the outstanding drawn balance, not on the full loan amount. Early in the build, when only the foundation draw has been released, your payment is small. As more of the loan funds toward framing and finishes, your interest-only payment grows along with the drawn balance. This is one of the most common points of confusion for first-time custom-home builders, who sometimes assume they’ll immediately owe interest on the entire $500,000 or $600,000 loan the day they close.
You’ll also need to decide how to handle the permanent rate. Two common approaches:
- Lock at closing: your permanent rate is set before construction even begins, which protects you if rates rise over the build period but means you don’t benefit if rates fall.
- Float-down closer to completion: you retain the ability to capture a lower rate if the market improves before conversion, usually for a fee or a slightly higher starting rate, with a defined window near the end of construction to exercise it.
Neither option is universally better. A lock-at-closing approach suits buyers who want payment certainty and are building during a period of rate volatility. A float-down suits buyers with more flexibility in their budget who are comfortable trading a bit of upfront cost for the chance at a better long-term rate. This is exactly the kind of program-fit decision worth walking through with a broker rather than defaulting to whatever a builder’s preferred lender offers.
Step 4: Run the Worked Numbers Before You Sign
Numbers make this process concrete in a way that general explanations can’t. Consider an illustrative example, using rates and figures as of 2026 that you’d want to verify against your actual quote: a $500,000 single-close construction-to-permanent loan, with a nine-month interest-only construction phase during which the drawn balance averages $250,000 (since draws release gradually rather than all at once) at an 8% construction-phase rate.
The math: $250,000 multiplied by 8% annual interest equals $20,000 per year, or roughly $1,667 per month during construction. That’s the payment you’d budget for while the home is being built, not the full $500,000 loan amount accruing interest, which would be a very different number.
Once the certificate of occupancy is issued and the loan converts, the permanent phase begins. Assume a 30-year fixed permanent rate of 6.75% on the full $500,000. Using a standard amortization calculation, principal and interest come to approximately $3,244 per month. That’s the payment you’ll carry for the life of the loan, barring a future refinance.
Now compare the single-close structure against a two-time-close alternative. With two-time-close financing, you pay closing costs on the construction loan, then pay a second full set of closing costs, origination fees, title work, appraisal, recording fees, when you refinance into the permanent mortgage. Duplicate closing costs on a loan this size commonly run in the neighborhood of $6,000, though the exact figure depends on your state, title company, and loan amount, and should be confirmed against a current loan estimate. The single-close structure avoids that second fee set entirely, since there’s no second closing, no second appraisal, and no second underwriting file. That $6,000 is not a rate advantage; it’s a structural savings baked into the process itself, which is why program structure deserves as much attention as the interest rate you’re quoted.
Step 5: Manage Inspections and Draw Requests During the Build
Once construction begins, the rhythm of the loan shifts from paperwork to logistics. Every draw requires a third-party inspection to confirm the corresponding phase of work is actually complete before funds release. If your builder doesn’t coordinate inspection scheduling with the broker’s timeline, you can end up with a finished framing stage sitting idle for days while everyone waits on an inspector’s availability. Building this coordination into your builder’s project management expectations up front saves real time over a nine-to-twelve-month build.
It’s also worth setting aside a contingency reserve, commonly 5% to 10% of the total contract price, to absorb change orders or material cost overruns without derailing your budget. Lumber prices, appliance upgrades, or a change to your electrical plan midway through the build can all push costs above the original contract. A reserve, confirmed with your builder as part of the initial budget conversation, keeps a $15,000 change order from becoming a financing crisis.
One of the more common mistakes at this stage isn’t about money at all: it’s paperwork. Builders sometimes submit draw requests that are missing required documentation, an unsigned lien waiver, an incomplete inspection report, or a cost breakdown that doesn’t match the original contract categories. Incomplete submissions delay payment to the builder, which can strain the relationship at exactly the point in the project when you need that relationship running smoothly. Reviewing draw paperwork alongside your builder before submission, rather than after a rejection, keeps the process moving and keeps trust intact on both sides.
Step 6: Convert to the Permanent Loan at Completion
Conversion is the moment the construction-to-permanent structure earns its name. Once your builder secures a certificate of occupancy and passes final inspection, those two events trigger an automatic modification of your existing loan into its permanent phase. In a true single-close product, this happens without a second underwriting file, a second credit pull, or a second closing appointment. You signed once, at the very beginning, for both phases.
Before that modification finalizes, confirm the timing of your as-built appraisal. Unlike the appraisal done at initial closing, which is based on plans and projected value, the as-built appraisal happens after construction is complete and must support the loan amount as built. If the finished home appraises below the loan amount, for example because of an unexpected market shift or because change orders altered the scope from what was originally appraised, that gap needs to be resolved before conversion, either through additional funds from you or a program-specific adjustment.
Escrow setup is another detail that catches first-time builders off guard. Property tax and insurance escrow typically begins at conversion into the permanent loan, not at the original construction closing, since the taxable value of raw land or a partially built home is different from the completed property’s value. Confirm with your broker exactly when escrow collection starts and what your first permanent-phase mortgage statement will include, so there are no surprises in the first month of homeownership.
Step 7: Choose Your Long-Term Term Structure
With the worked numbers from Step 4 in front of you, the term decision comes down to what you can comfortably carry long-term versus what you save in total interest. A 30-year term at 6.75% on $500,000 runs approximately $3,244 per month in principal and interest, as calculated earlier. A 15-year term at a comparable or slightly lower rate would carry a meaningfully higher monthly payment but a much lower total interest cost over the life of the loan. The right choice depends on your cash flow during the years immediately following move-in, not just the total interest figure, since new homeowners often face unexpected costs, landscaping, window treatments, furniture, in the first year that a tighter monthly budget can’t absorb.
If your target loan amount sits above the 2026 conforming limit of $806,500, confirm early whether you need a jumbo construction-to-permanent program rather than a conforming one. Jumbo construction financing often comes with stricter reserve requirements and a narrower pool of broker options, so this is worth settling before you finalize your builder contract, not after.
It’s also useful to understand how large national retail lenders structure these products compared with a broker-guided path. Rocket Mortgage and Movement Mortgage both offer construction-to-permanent financing, but as retail operations they typically work from a fixed menu of in-house programs. A broker-guided approach can shop your specific program, conventional, VA, jumbo, or a Non-QM structure for self-employed borrowers, across multiple wholesale sources to match your build timeline and budget rather than fitting you into one lender’s standard product.
Comparing Construction-to-Permanent Programs by Fit
Program selection matters more than any single rate quote, since the structure determines your down payment, your reserve requirements, and how flexible the draw process can be. Duane Buziak, NMLS #1110647, works through this comparison with clients before a builder contract is even signed, since backing out of a program mid-construction is far more disruptive than choosing correctly at the start.
| Program | Best Fit For | Primary Advantage | Trade-Off to Evaluate |
|---|---|---|---|
| Conventional Construction-to-Permanent | Buyers with strong credit and a down payment near 20% | Widest builder acceptance, straightforward conforming underwriting | Loan amount capped at $806,500 conforming limit for 2026 |
| VA Construction-to-Permanent | Eligible veteran and active-duty borrowers building a primary residence | Remains 100% LTV where eligible, no down payment required | Fewer approved builders accept VA construction terms; longer builder-approval step |
| Jumbo Construction-to-Permanent | Custom builds above the conforming limit, move-up or luxury buyers | Finances higher-value builds in a single close | Larger reserve requirements and narrower broker/investor pool |
| Non-QM / DSCR-Adjacent Construction Financing | Self-employed borrowers or investors building rental property | Underwrites on alternative income or projected rental cash flow | Typically higher rate and larger down payment than conventional |
Where VA financing applies, it’s worth noting the contrast directly: VA construction-to-permanent loans remain available at 100% LTV where eligible, a structure that differs from the standard retail construction offerings at lenders like Rocket Mortgage or Movement Mortgage, and from what Veterans United and other VA-focused originators typically present. Confirming builder eligibility for VA construction financing early avoids a late-stage scramble to find an approved builder.
Frequently Asked Questions on the Construction-to-Permanent Process
How long does construction-to-permanent closing take? The single closing itself typically takes 45 to 60 days from application to signing, depending on how quickly your builder contract, plans, and cost breakdown are finalized.
Construction-to-permanent vs. two-time-close, which costs less? Single-close construction-to-permanent financing generally costs less overall because it avoids a second set of closing costs, commonly around $6,000 on a loan this size, that a two-time-close structure requires.
Do I make full mortgage payments during construction? No, you make interest-only payments calculated on the drawn balance released so far, not on the full loan amount.
Can I pre-qualify without hurting my credit? Yes, a NoTouch Credit Pull lets you pre-qualify and compare construction-to-permanent program options without a hard inquiry on your credit report.
Is a construction-to-permanent loan the same as a 203k loan? No, a 203k finances renovations to an existing structure, while a construction-to-permanent loan finances a new build from the ground up.
Does my builder need special approval? Yes, most programs require the builder to be licensed, insured, and often pre-approved by the broker before funding can begin.
What happens if the as-built appraisal comes in low? The gap between appraised value and loan amount must be resolved, often with additional funds, before the loan can convert to its permanent phase.
Should I lock my rate at closing or use a float-down? Lock at closing if you want payment certainty through the build; choose a float-down if you’re willing to pay a bit more upfront for a chance at a lower rate near completion.
How much contingency reserve should I budget? A reserve of 5% to 10% of the total contract price is a reasonable planning figure to cover change orders or material cost overruns, confirmed with your builder.
When does tax and insurance escrow start? Escrow collection typically begins at conversion into the permanent loan, not at the original construction closing.
