Building is the one transaction where the financing structure genuinely changes the outcome. A one-time close means you sign once, at the start, and the loan converts to a permanent mortgage when the house is finished. The alternative — closing twice and requalifying at the end — means proving yourself again a year from now at whatever rates and whatever underwriting standards exist then. If your income, your credit or the market has moved in the meantime, that is a real risk you did not need to take.
You are building on land you own, or buying the land and building together
You want a custom home rather than a builder's inventory house
You are adding a substantial addition rather than a cosmetic remodel
You would rather not requalify a year from now to obtain permanent financing
You are a veteran — VA construction financing exists, though few lenders offer it
How it works
One closing, not two
A one-time-close construction-to-permanent loan is underwritten and closed before construction begins. During the build it behaves as an interest-only line drawn in stages. When the certificate of occupancy is issued, it converts to a standard amortising mortgage — no second closing, no second set of costs, no second approval.
The alternative, a two-time close, means a short-term construction loan followed by a separate permanent mortgage you must qualify for at completion. It is sometimes unavoidable and occasionally cheaper, but the requalification risk is real and it is borne entirely by you.
The builder is underwritten too
This surprises people more than anything else about construction lending.
The lender reviews your builder's licence, insurance, financial standing, references and track record, and separately approves the plans, the specifications and the budget. A builder who has not been through this before will slow the file down considerably, and some do not pass at all.
Bring us the builder early — before you sign a construction contract if possible. Discovering at underwriting that your chosen builder cannot be approved is a genuinely bad position to be in.
Draws are released against inspected work
Funds do not arrive in a lump. They release in stages as work is completed and verified by inspection — typically at foundation, framing, mechanical rough-in, drywall, and completion, though schedules vary.
Your builder must be comfortable operating that way rather than receiving a large deposit upfront. Established builders expect it. Smaller operators sometimes cannot carry the cash flow, and that is worth establishing before you commit to them.
You pay interest only on what has actually been drawn, so payments start small and grow as the build progresses.
The appraisal values a house that does not exist yet
An appraiser reviews the plans, specifications and budget and produces a subject-to-completion value — what the finished home will be worth. The loan is sized against that figure. If it comes in below your total cost to build, you cover the difference in cash, which is one of the more painful surprises in construction lending. Overbuilding for the neighbourhood is the usual cause: the finest house on the street rarely appraises for what it cost.
Land can often be folded in
If you already own the land free and clear, its value typically counts toward your equity — sometimes covering the entire down payment requirement. If you are buying land and building together, both can usually be financed in the same transaction. If you bought the land recently with a loan, that balance is generally paid off at closing and rolled into the construction loan.
The details that decide it
Contingency is not optional
Every construction budget should carry a contingency line, and lenders will usually require one. Ten percent is a common minimum and fifteen is safer.
Things move: material prices change between bid and purchase, sites reveal problems once excavation starts, and buyers make changes they swore they would not make. A change order for something you decided you wanted after seeing the framing is the most predictable overrun in the business.
Without contingency, overruns come out of your pocket in cash, at the least convenient moment. With it, they come out of the budget as designed.
How the rate works during and after the build
Approaches vary. Some one-time-close programmes lock a rate for the permanent loan at the outset, which is valuable protection if rates rise during a twelve-month build. Others use a float-down allowing you to capture an improvement if rates fall before completion. Some lock only at conversion, leaving you exposed. This is one of the most consequential differences between construction lenders and it is rarely the headline — ask specifically.
VA and USDA construction options
VA construction financing exists and can be genuinely zero down, but relatively few lenders offer it, and finding them is a real part of what a broker does. USDA also has a construction-to-permanent option in eligible rural areas with the same zero-down structure. Both are more paperwork than conventional construction lending and both have shorter lender lists. If you qualify for either, it is worth the extra effort — building with no down payment is a meaningful advantage.
Timeline, realistically
Setting up a construction loan takes longer than a purchase — plans, budget, builder approval and a subject-to-completion appraisal all have to be assembled before closing. Then the build itself runs on the builder's schedule and the weather, and lenders set a maximum construction period with extension provisions. Start the financing conversation months before you intend to break ground, not weeks.

You expect circumstances to improve
One-time close is the safer structure for almost everyone, and the requalification risk in a two-time close is consistently underrated by borrowers who feel confident about their income today. Two-time can win if you have a specific reason to expect materially better qualifying at completion.
What people get wrong
Choosing the builder before checking they can be approved
Lenders underwrite the builder as well as you. Signing a construction contract with someone who cannot pass is an expensive way to find out.
Budgeting with no contingency
Overruns are not a risk, they are a near-certainty. Without a contingency line, they come out of your cash at the worst possible time.
Overbuilding for the neighbourhood
The subject-to-completion appraisal has to support the loan. Building the most expensive house on the street is the most reliable way to get an appraisal below your cost.
Not asking how the rate is handled during the build
Locked, float-down, or exposed at conversion — the difference is substantial over a twelve-month build and it is rarely volunteered.
Underestimating change orders
Every change costs money and most cost time. Decisions made after framing are the expensive ones. Settle specifications before you break ground.
Building in Wilson County and Middle Tennessee
There is still genuine land to build on across Wilson County — out past Lebanon toward Watertown, and through the county between here and the Smith County line — at prices that make custom building a realistic alternative to buying existing inventory. Two local points matter. First, much of that same ground is USDA eligible, which means a construction-to-permanent loan with no down payment is worth investigating before you assume you need twenty percent. Second, Rutherford County around Murfreesboro carries the region's heaviest new-construction activity, and buyers there are usually choosing between a production builder's inventory home with the builder's own preferred lender, and building custom with independent financing. Those are very different transactions with very different economics, and the builder's lender will only ever explain one of them.
The honest part
Construction lending is slower to arrange than a purchase and there are more ways for it to go sideways — budget overruns, builder delays, weather, and an appraisal that comes in under your cost to build. You will be managing a project, not just a loan, and the lender's draw and inspection process adds administration on top of everything else you are doing. If you want a house next spring and are not prepared for any of that, buying existing is a legitimate answer and we will say so. Building is deeply rewarding when it goes well and genuinely stressful when it does not.
Common questions
What is a one-time-close construction loan?
A single loan that funds construction and then converts to permanent financing with no second closing, no second set of costs, and no requalifying at completion.
Do I make payments while the house is being built?
Usually interest-only on the amount drawn so far, which starts small and grows as the build progresses. Full amortising payments begin at conversion.
Can I use a VA loan to build?
Yes, VA construction financing exists and can be zero down, but relatively few lenders offer it. Finding the ones that do is a real part of what a broker adds here.
How much do I need to put down to build?
Typically ten to twenty percent of total cost, though land you already own often counts toward it — sometimes covering the requirement entirely. VA and USDA construction options can be zero down.
Does the lender have to approve my builder?
Yes. Licence, insurance, financial standing, references and track record are all reviewed, along with the plans and budget. Bring the builder into the conversation early.
What happens if the build costs more than expected?
Overruns come from your contingency if you budgeted one, and from your cash if you did not. This is why lenders require contingency and why ten percent is a floor rather than a target.
Can I act as my own general contractor?
Very few lenders permit owner-builder arrangements, and those that do require demonstrable construction experience. For most borrowers the answer is no.
What if the appraisal comes in below my cost to build?
You cover the difference in cash. The usual cause is overbuilding relative to the neighbourhood, which is worth testing against comparable sales before finalising plans.
