Why Construction Loans Are Different from Regular Mortgages
If you've bought a house before, you know how a mortgage works. You get approved, find a house, close, and start making payments on day one. Simple enough. But building a house? That's a whole different animal.
When you build a home, there's no finished house to use as collateral. There's a plot of land, a set of plans, and a hole in the ground. Banks can't hand you $400,000 and say "go build." They need to protect their investment. That's where construction loans come in — they're structured completely differently from standard mortgages, and honestly, they take some getting used to.
Here's the thing that surprises most people: construction loans aren't disbursed as a lump sum. The lender pays the builder in stages — called "draws" — as milestones are completed. You pay interest-only on the amount drawn so far, not on the full loan. And once the house is finished, the loan either converts to a permanent mortgage or gets paid off with a new loan.
In this guide, I'll walk through every type of construction loan, the down payment requirements, the rate structure, how the draw process works, and the gotchas that trip up first-time builders. If you're thinking about building your own home in 2026, this is everything you need to know.
🏗️ Quick Facts: Construction Loans in 2026
- Down payment: typically 20%–25% minimum
- Rates: 7.0%–8.5% during construction (interest-only)
- Construction phase: 6–18 months (12 months typical)
- Draw schedule: 5–7 payments tied to construction milestones
- Contingency reserve: 5%–10% of total budget required
- Closing costs: $5,000–$12,000 for one-time close
Construction-to-Permanent vs. Stand-Alone Construction Loans
These are the two main options, and the one you choose has a big impact on your closing costs, your interest rate, and how much work you'll have to do during construction.
Construction-to-Permanent Loan (One-Time Close)
This is the option most people choose, and for good reason. You apply once, close once, and pay closing costs once. The loan starts as a construction loan — with interest-only payments on the drawn amount — and automatically converts to a permanent mortgage (fixed or adjustable) once the home is finished. One closing, one set of fees, one underwriting process. Simple.
With a one-time close loan, your interest rate is locked before construction begins. In 2026, that means you're locking at the current rate plus a premium for the construction phase. After construction, the rate either stays the same (if it's a fixed-rate conversion) or adjusts to the permanent rate based on the terms you agreed to at closing.
The big advantage: you're protected from rate increases during the 6-18 months of construction. If rates go up while your house is being framed, it doesn't matter — your permanent rate was locked at closing. In a rising rate environment like 2026, this is a significant benefit.
Stand-Alone Construction Loan (Two-Time Close)
With this option, you take out a construction loan first, build the house, and then apply for a separate permanent mortgage at the end. You close twice, pay closing costs twice, and go through underwriting twice.
Why would anyone do this? Two reasons:
- Lower initial costs: You might get a marginally better rate during construction because the lender doesn't have to price in the permanent mortgage terms.
- More flexibility at conversion: If rates drop during construction (unlikely in 2026, but possible), you can shop for the best permanent mortgage rate when construction finishes.
The downside? You need to qualify twice. If your credit score drops during construction, or your income changes, you might not qualify for the permanent mortgage and could be stuck. You also pay $3,000 to $7,000 more in closing costs. For most people, the one-time close is the better option.
| Feature | One-Time Close | Two-Time Close |
|---|---|---|
| Number of closings | 1 | 2 |
| Closing cost estimate | $5,000 – $12,000 | $8,000 – $19,000 |
| Rate lock at closing | Yes — permanent rate locked upfront | No — only construction rate locked |
| Qualify for mortgage | Once | Twice |
| Construction rate | Typically 0.25% – 0.5% higher | Slightly lower |
| Permanent rate shopping | Not available | Shop at completion |
| Best for | Most borrowers | Borrowers expecting rate drops |

Down Payment Requirements — Why They're Higher
Here's something that frustrates a lot of builders: construction loans require bigger down payments than regular mortgages. While you can put 3% down on an existing home with a conventional loan, construction lenders typically want 20% to 25% down. Why?
Because construction loans are riskier. There's no finished house to sell if the borrower defaults. The lender is funding a project that could go over budget, hit delays, or — worst case — end up half-built. The larger down payment gives them a cushion and demonstrates that you're financially committed to completing the project.
The good news: your down payment can come from multiple sources:
- Cash: The most straightforward. Money in a bank account for at least 2-3 months (to season it).
- Land equity: If you already own the lot free and clear, its value counts toward your down payment. Bought a lot for $80,000? That's $80,000 of your required equity.
- Home equity from your current house: If you're selling your current home or using a bridge loan, that equity can be rolled in.
- Gifts: Family gifts are allowed, but with strict rules. The gift donor must document the transfer, and your down payment typically needs to come entirely from your own funds if you're putting less than 20% down.
| Loan Type | Minimum Down Payment | Construction Phase Terms | Best Use Case |
|---|---|---|---|
| Conventional One-Time Close | 20% (some 15%) | Interest-only draws; rate-lock for permanent | Standard new construction |
| FHA 203(k) Renovation | 3.5% | Single-close; limited to $35k-$50k repairs | Existing home gut renovation |
| FHA Construction-to-Perm | 3.5% | HUD-approved builder required | First-time builders, limited cash |
| VA Construction Loan | 0% | VA-approved builder; strict timeline | Veterans and active duty |
| USDA Construction Loan | 0% | Rural areas; income limits apply | Rural home construction |
| Owner-Builder Loan | 30%+ | Proven construction experience required | DIY builder acting as GC |
Requirements as of August 2026. VA construction loans are less common — not all VA lenders offer construction-to-permanent products.
How the Draw Process Works
The draw process is the single biggest difference between a construction loan and a regular mortgage, and it's where most confusion happens. Here's the deal:
The lender doesn't hand over all the money at once. Instead, they release funds in stages called "draws" as the builder completes specific milestones. A typical draw schedule looks like this:
| Draw # | Milestone | Typical % of Total Loan | What the Lender Checks |
|---|---|---|---|
| 1 | Foundation / Slab | 10%–15% | Footings poured, forms set, inspected |
| 2 | Framing / Rough-In | 20%–25% | Walls up, roof sheathed, windows installed |
| 3 | Mechanical Rough-In | 10%–15% | Plumbing, electrical, HVAC rough-in completed |
| 4 | Drywall / Interior | 15%–20% | Drywall hung, taped, mudded; insulation installed |
| 5 | Trim / Fixtures | 10%–15% | Cabinets, flooring, trim, plumbing fixtures installed |
| 6 | Final / Certificate of Occupancy | 10%–15% | CO issued, final inspection passed |
Draw schedules vary by lender and project complexity. Some lenders use 5 draws, others use 7 or more. Builder may request draws at different thresholds.
Here's how each draw works in practice:
- Builder completes the milestone (e.g., foundation is poured and cured)
- Builder submits a draw request to the lender, often with invoices and photos
- Lender or a third-party inspector verifies completion — they visit the site, check the work, and confirm it matches the draw request
- Lender releases funds — typically within 3-7 business days of inspection approval
- You get a statement showing your new loan balance and your interest-only payment for the next period
One thing builders and homeowners both hate: the inspection gap. If the lender's inspector takes a week to get to the site, the builder is sitting idle waiting for funds. Good builders factor this into their schedule. Good homeowners build a friendly relationship with the inspector.
Interest Rates and Payments During Construction
During construction, you pay interest-only payments. But here's the key: you only pay interest on the amount that's been drawn so far, not the full loan amount. So in month one, you might pay interest on $40,000 (the foundation draw), and by month 12, you're paying interest on the full $350,000.
In 2026, construction loan rates range from 7.0% to 8.5% for the construction phase, typically tied to the prime rate (currently 7.5%) plus a margin. Most construction loans use a variable rate during the construction phase, meaning your payment can go up or down as the prime rate changes. This is one of the risks — if the Fed raises rates during your 12-month build, your interest-only payment goes up.
Let's run a realistic example. Say you're building a $450,000 home with a $360,000 construction loan (20% down). Your draws are spread across 10 months:
| Month | Amount Drawn | Total Drawn to Date | Interest-Only Payment (7.5%) |
|---|---|---|---|
| 1 (Foundation) | $50,000 | $50,000 | $313 |
| 2 (Framing) | $80,000 | $130,000 | $813 |
| 4 (Mechanical) | $50,000 | $180,000 | $1,125 |
| 6 (Drywall) | $70,000 | $250,000 | $1,563 |
| 8 (Trim) | $50,000 | $300,000 | $1,875 |
| 10 (Final) | $60,000 | $360,000 | $2,250 |
Example assumes 7.5% interest rate during construction. Actual rate may vary. Interest calculation: balance × rate ÷ 12.
Notice how the payment starts low and ramps up. Your $313 payment in month one becomes $2,250 by month ten. That's intentional — it keeps cash in your pocket during the early months when unexpected costs usually pop up. But you need to budget for the rising payments. A common mistake builders make is assuming the payment will stay flat.
Working With Builders — What the Lender Requires
Your builder matters to the lender just as much as your credit score does. Lenders want to know the builder is licensed, bonded, insured, and financially stable enough to finish your project. Here's what most lenders want to see:
- Valid contractor's license for your state — check it's active and doesn't have complaints
- General liability insurance — typically $1 million minimum coverage
- Workers' compensation insurance — protects you from liability if a worker is injured on your property
- Completed projects — at least 3-5 comparable homes built in the last 2 years
- Financial statements — the builder needs to show they're solvent and can handle the cash flow timing
- Fixed-price contract — the contract must specify a fixed price, detailed scope of work, and completion timeline
Here's a tip that saved one of my clients $30,000: verify the builder's prior projects by talking to those homeowners directly. Not just the references the builder gives you — find your own. Drive around neighborhoods where the builder has worked and knock on doors if you have to. Ask about change orders, timelines, and whether the builder finished within budget.
The fixed-price contract is key. A cost-plus contract (where you pay the builder's costs plus a percentage) is risky because you don't know the final price until the end. Lenders prefer fixed-price because it gives them a firm number to underwrite against. If your builder insists on cost-plus, that's a red flag.
The Contingency Reserve — Why You Need It
Every construction loan includes a contingency reserve — typically 5% to 10% of the total construction budget. This is money set aside to cover cost overruns, change orders, or unexpected site conditions. On a $400,000 build, that's $20,000 to $40,000 held in reserve.
The contingency isn't optional — lenders require it. And honestly, they're right to. According to the National Association of Home Builders, roughly 65% of custom home builds experience at least one unexpected cost increase. The average overrun is about 7% of the total budget. Common sources:
- Site conditions — unexpected rock removal, soil remediation, or groundwater issues
- Material price increases — lumber, steel, and concrete prices have been volatile in 2026
- Change orders — you decide you want better cabinets or a different floor plan (this is the most common one)
- Permit delays — extended inspection timelines that push the builder into overtime
- Labor shortages — which can force you to pay premium rates to keep the project on schedule
If you finish construction without using the contingency, the unused funds reduce your loan balance. In a one-time close loan, that means a smaller permanent mortgage. If you need more than the contingency, you pay out of pocket — which is why having your own reserve fund beyond what the lender requires is a smart move.
One-Time Close Construction Loan Rates in 2026
As of mid-2026, one-time close construction loan rates are pricing roughly 0.75% to 1.5% above standard 30-year fixed mortgage rates. With the standard 30-year fixed at 6.625%, a construction-to-permanent loan might carry a permanent rate of 7.25% to 8.0% depending on your credit, down payment, and the lender.
Here's the rate breakdown by credit tier for a typical one-time close construction loan in August 2026:
| Credit Score | Down Payment | Construction Rate (Interest-Only) | Permanent Rate (Fixed 30yr) |
|---|---|---|---|
| 760+ | 25% | 7.00% variable | 7.125% |
| 720–759 | 20% | 7.50% variable | 7.500% |
| 680–719 | 20% | 8.00% variable | 7.875% |
| 640–679 | 25% | 8.50% variable | 8.375% |
Rates are estimates for a $400,000 loan as of August 2026. Actual rates vary by lender, region, property type, and loan-to-value. Construction phase rate is typically prime (7.5%) + margin.
VA construction loans are worth mentioning separately. If you're a veteran, some lenders offer construction-to-permanent VA loans with zero down payment. The rates are typically 0.25% to 0.5% lower than conventional construction loans. The catch? Not all VA lenders offer this product, and you need a VA-approved builder — plus the builder has to agree to VA's inspection requirements, which some builders won't do because of the paperwork.
Land as Equity — A Smart Strategy
If you already own the land you're building on, you've got a head start. Land that's paid off counts as equity toward your down payment. Here's how it works:
Say you own a lot worth $80,000 free and clear. You want to build a $400,000 home. Total project cost: $400,000. If your lender requires 20% down ($80,000), your land equity satisfies the entire requirement. Zero cash needed for the down payment.
Even if you still owe money on the land, the equity portion counts. If the lot is worth $80,000 and you owe $30,000, your equity is $50,000 — which counts toward your down payment. You just need to cover the remaining portion in cash.
But there's a nuance: the land needs to be appraised as a developed building site. If the lot doesn't have access to utilities, isn't zoned for residential, or has environmental issues, its value as collateral is limited. Check these before you assume the lot value covers your down payment.
Budgeting for the Total Cost of Building
Here's something the glossy builder brochures don't tell you: the cost of building a home goes far beyond what the lender finances. You need to budget for:
- Architect and design fees: $5,000–$15,000 for a custom home plan
- Permits and impact fees: $2,000–$10,000 depending on your locality
- Utility connections: $3,000–$15,000 for water, sewer, electric, gas, internet
- Site preparation: $3,000–$20,000 for clearing, grading, soil testing
- Temporary housing during construction: 6-18 months of rent or mortgage on your current home
- Landscaping and hardscaping: $5,000–$25,000 (often not included in construction loan)
- Furnishings and window treatments: Don't forget the new house needs blinds, curtains, furniture
I tell my readers to budget at least 10% to 15% of the total project cost in cash beyond what the construction loan covers. If your build is $400,000, have $40,000 to $60,000 in liquid cash on top of your down payment. You might not need all of it. But the builders who come up short are the ones who end up stressed and making bad decisions.
Construction Loan Alternatives
If a construction loan doesn't work for you — maybe you don't have 20% down, or you can't qualify for the higher rate — there are alternatives:
- Builder financing: Large production builders often have their own mortgage companies and offer below-market rates or reduced down payments. The catch? You must use their builder and their floor plans. No custom homes.
- Home equity loan on current house: If you have equity in your current home, you could take out a HELOC to fund the construction and then get a regular mortgage on the new home. This is risky because you're leveraging your current home.
- FHA 203(k) renovation loan: Not for building from scratch, but if you're buying a fixer-upper and doing a major renovation, the 203(k) program wraps the purchase and renovation costs into one loan with 3.5% down. Use our FHA loan guide for details.
- Cash-out refinance on land: If you own land outright, some lenders offer cash-out refinancing to fund construction, though the rates are typically higher than construction loans.
Making the Decision: Is Building Right for You?
Building a home gives you exactly what you want — the perfect layout, the finishes you've dreamed about, a brand-new house with no previous owners' wear and tear. But it comes with trade-offs: higher costs, a longer timeline, and more stress than buying an existing home.
Before you commit, ask yourself these questions:
- Can you afford to tie up 20-25% down payment plus 10-15% in additional cash reserves?
- Are you comfortable with 6-18 months of uncertainty about your completion date?
- Can you handle cost overruns without panicking?
- Do you have a licensed, experienced builder you trust?
- Is building actually cheaper than buying in your market? (In some areas, it's not — check recent sales and construction costs per square foot.)
If you answered yes to all five, a construction loan might be your path. Start with our affordability calculator to figure out what total project cost fits your budget, and check current mortgage rates to see what the permanent phase would cost you. Talk to at least 3 lenders who specialize in construction loans — not every retail lender offers them. Construction lending is a niche, and you want someone who does it every day.

Frequently Asked Questions About Construction Loans
Primary Sources
Rates, limits, and program rules change. Always confirm current figures with the issuing agency.
What is the minimum down payment for a construction loan in 2026?
Most construction loans require 20% to 25% down payment in 2026. Some construction-to-permanent loans backed by FHA (203k) allow as little as 3.5% down, but conventional construction loans typically require substantial equity. The down payment can come from cash, equity in land you already own, or a combination. If you own the land free and clear, the land equity can count toward the down payment.
How do construction loan interest rates compare to standard mortgages?
Construction loan rates are typically 0.5% to 1.5% higher than standard mortgage rates in 2026. During the construction phase, you pay interest-only on the amount drawn so far at a variable rate (usually prime plus a margin). Once construction is complete and the loan converts to a permanent mortgage, the rate becomes fixed or adjustable at standard mortgage rates. Current construction loan rates range from 7.0% to 8.5% depending on the lender and your credit profile.
Can I build my own house with a construction loan?
Yes, but it's harder. Most construction lenders require a licensed, bonded general contractor. If you want to act as your own general contractor (owner-builder), you'll typically need a larger down payment (30%+), proven construction experience, and a more extensive application. Some lenders offer owner-builder construction loans specifically for experienced DIY builders, but the requirements are strict.
What happens if construction costs exceed the loan amount?
Construction loans include a contingency reserve — typically 5% to 10% of the total budget — to cover cost overruns. If costs exceed the total loan plus contingency, the borrower is responsible for covering the difference out of pocket. This is why having a cost contingency and a realistic builder's estimate is essential. Most lenders require a signed fixed-price contract with the builder to minimize this risk.
How long does a construction loan last?
The construction phase of a loan typically lasts 6 to 18 months, with 12 months being the most common. If construction isn't completed within the construction loan term, you can request an extension — but extensions aren't guaranteed and come with fees. The permanent mortgage phase begins after construction completion and runs the full term (15 to 30 years).
Do I pay two sets of closing costs with a two-time close loan?
Yes, with a two-time close construction loan, you pay closing costs twice — once at the start of the construction loan and again when the permanent mortgage is secured. One-time close loans (construction-to-permanent) require only one set of closing costs. The savings on the one-time close can be $3,000 to $7,000 depending on the loan amount and lender fees.
