Building a home from scratch is one of the more ambitious things you can do in real estate. It requires a specific type of financing that works very differently from a standard mortgage — and understanding those differences upfront can save you a lot of frustration down the line.
A construction loan is a short-term loan designed to fund the building or substantial renovation of a residential property. Unlike a traditional mortgage, where the lender hands over a lump sum to purchase an existing home, construction loans release funds in stages as work is completed. Rates are typically variable, qualification criteria are stricter, and the whole structure is built around a project timeline rather than a property value.
This guide covers everything you need to know: how construction loans work step by step, the main loan types, what lenders require, common pitfalls, and how to apply.
How Does a Construction Loan Work?
At its core, a construction loan is a temporary line of credit that covers the cost of building a home. The initial term is typically 12 to 18 months — just long enough to get a house built. At the end of that term, you either repay the loan in full or convert it into a permanent mortgage, depending on the loan structure you chose.
Here is what the process looks like from start to finish.
Step 1: Assess your finances
Before anything else, lenders will review your credit history, income, assets, and existing debts. Most construction loan lenders require a credit score of at least 680, though some will consider borrowers at 620. Your debt-to-income ratio should generally sit below 45%.
Down payments are higher than on conventional mortgages. Plan for 20% to 25% of the total project cost. The property under construction acts as collateral, but since it doesn’t yet exist at the time of application, lenders are taking on more risk — hence the stricter requirements. You can use our construction loan calculator to get a rough sense of numbers before you approach a lender.
Step 2: Choose a licensed builder
Lenders don’t just approve borrowers; they also scrutinize the builder. Your general contractor needs to be licensed and insured, and the lender will typically want to review their company financials, references, and credentials before giving the green light. The reason is simple: the funds get paid directly to the builder, not to you.
Choose carefully. A contractor with a poor track record or thin financials can hold up your draw schedule, complicate your lender relationship, and cost you more in the long run.
Step 3: Prepare your project documentation
This is where construction loans differ most sharply from standard mortgages. Beyond the usual financial paperwork, you’ll need to provide:
- Architectural drawings and detailed floor plans
- A full itemized budget
- A signed contract with your general contractor
- A project timeline with construction phases
- Proof that all necessary permits have been obtained or applied for
- Builder’s risk insurance documentation
Lenders use all of this to structure your draw schedule and confirm the project is viable before committing funds.
Step 4: The draw schedule
Once approved, you enter the draw schedule. Instead of receiving the full loan amount upfront, funds are released in stages tied to construction milestones. Common draw points include completion of the foundation, framing, roofing, mechanical rough-in, and final inspection.
Before each draw is released, a lender-appointed inspector visits the site to verify that the milestone has been reached. The inspector’s report determines how much gets paid out to the builder for that phase. During construction, you pay interest only on the funds that have been drawn, not on the full loan amount. This keeps your monthly outgoings lower while the project is underway.
Step 5: Project completion and loan conversion
Once construction is finished and the home passes its final inspection, your loan enters its end phase. Depending on the loan type, you’ll either convert it to a permanent mortgage or repay it in full (often by taking out a separate mortgage). Principal payments begin at this point.
Construction Loan vs. Traditional Mortgage: The Key Differences
People often ask why they can’t just use a regular mortgage to build a home. The short answer is that a mortgage is secured against an existing property. There’s nothing to appraise until the house is built, so the risk profile is completely different.
| Feature | Construction loan | Traditional mortgage |
|---|---|---|
| Purpose | Funds the building of a new home | Purchases an existing property |
| Loan term | 12–18 months | 15–30 years |
| Fund disbursement | Released in stages (draws) tied to milestones | Lump sum at closing |
| Interest rate | Variable, typically 1–1.5% above conventional rates | Fixed or adjustable |
| Repayments during loan | Interest only on drawn funds | Principal + interest from day one |
| Down payment | Typically 20–25% | As low as 3% (conventional) |
| Credit score | 680+ typical (620 minimum with some lenders) | 620+ for most conventional loans |
| Collateral | Future property (higher lender risk) | Existing property |
Types of Construction Loans
Not all construction loans are the same, and the type you choose will affect your costs, closing timeline, and how much flexibility you have if your financial situation changes during the build.
1. Construction-to-permanent loan
Also called a one-time-close loan, this starts as a construction loan and converts automatically into a permanent mortgage once the home is complete. You go through a single closing, pay one set of closing costs, and choose your long-term rate structure (fixed or adjustable) upfront. This is the most common choice for borrowers building a primary residence.
Government-backed versions exist too. An FHA construction-to-permanent loan has more lenient approval standards, while a VA construction loan is available to eligible veterans and often requires no down payment.
2. Construction-only loan
This covers the build phase only. Once construction is complete, you repay the loan in full, usually by taking out a separate mortgage. The upside is that you can shop for the best mortgage rate at the end of the project. The downside is two closings, two sets of fees, and the risk that your financial situation changes during construction and you can’t qualify for the second loan. For most borrowers, that risk is not worth the potential rate savings.
3. Construction-to-permanent end loan
Similar to the construction-to-permanent structure, but with a separate closing at conversion. Some lenders offer this when they prefer to underwrite the permanent mortgage independently rather than lock in terms at the start of construction.
4. Renovation loan
If you’re improving an existing property rather than building from scratch, renovation loans are the relevant product. Options include the FHA 203(k), Fannie Mae HomeStyle, Freddie Mac CHOICERenovation, and VA or USDA renovation loans. These combine purchase (or refinance) and renovation costs into a single loan. New Silver’s fix and flip loans serve investors renovating properties for resale.
5. Owner-builder loan
If you’re a licensed contractor planning to act as your own general contractor, you may qualify for an owner-builder loan. These are harder to get than standard construction loans because lenders face more risk without an independent contractor managing the project. Expect to provide detailed evidence of your credentials and experience.
6. Ground-up construction loan (hard money)
For real estate investors building to sell or rent, private lenders like New Silver offer ground-up construction loans with faster approvals and more flexible terms than conventional lenders. New Silver’s Ground Up loan covers up to $5,000,000, offers loan terms up to 18 months, and can fund in as little as five days. Approval in 48 hours is standard. These loans are designed for investors who need speed and flexibility, not the slow underwriting timeline of a bank.
Pros and Cons of Construction Loans
| Pros |
|---|
| Interest-only payments during the build You only pay interest on drawn funds, keeping costs lower while construction is underway |
| Flexible draw structure Funds release as milestones are hit, so you borrow only what you need, when you need it |
| Build to your exact specs Finance a property built precisely to your needs rather than compromising on existing stock |
| One-time-close option saves on fees Construction-to-permanent loans roll into a mortgage with a single closing, cutting out a second round of closing costs |
| Cons |
|---|
| Higher rates than conventional mortgages Variable rates typically run 1–1.5 percentage points above standard 30-year mortgage rates |
| Larger down payment required Most lenders require 20–25% down versus as little as 3% on conventional mortgages |
| Strict qualification criteria Credit score, DTI, builder credentials, and detailed plans — the approval bar is higher than for a purchase mortgage |
| Construction-only loans mean two closings A separate end mortgage means two sets of closing costs and going through underwriting twice |
Construction Loan Requirements: What Lenders Check
Qualifying for a construction loan takes more preparation than a standard mortgage application. Here’s a consolidated checklist of what most lenders want to see.
Financial requirements
- Credit score of 680 or higher (some lenders allow 620)
- Debt-to-income ratio below 45%
- Proof of stable income (pay stubs, two years of tax returns)
- Sufficient cash reserves for the down payment and contingency fund
- Down payment of 20–25% of total project cost
Project documentation
- Signed contract with a licensed general contractor
- Itemized project budget
- Detailed construction timeline with phased milestones
- Architectural drawings and floor plans
- Permits obtained or in process
- Zoning compliance documentation
Builder and contractor credentials
- Valid contractor’s license and insurance certificate
- Builder’s financial statements
- References and project history
- Builder’s risk insurance policy
Property appraisal
An appraiser will assess the lot value and blueprints to estimate the finished home’s value. For construction-to-permanent loans, this figure becomes the collateral basis for your mortgage. Lenders want to see that the finished home will be worth what they’re lending.
If you already own the land, you may be able to use its equity as part or all of your down payment, but check with your specific lender, as policies vary.
What Does a Construction Loan Cover?
Construction loans typically fund the following:
- Raw land purchase (or the remaining balance if you already own it)
- Site preparation and excavation
- Foundation, framing, roofing, and structural work
- Mechanical systems (plumbing, electrical, HVAC)
- Interior finishing (flooring, fixtures, cabinetry)
- Building permits
- Contractor labor
Not typically covered: architectural and design fees, landscaping (in most cases), home furnishings, and any costs incurred before the loan closes. Budget for these separately.
Common Pitfalls and How to Handle Them
Construction projects rarely go exactly to plan. Here are the most frequent issues borrowers run into and the practical ways to mitigate them.
Budget overruns
Material prices can rise during a multi-month build, and unexpected site conditions — poor soil, hidden utilities, weather delays — can add costs quickly. Build a contingency reserve of 10–15% of your total budget before you start. Don’t treat that buffer as spending money; it’s insurance.
Draw delays
If a lender’s inspector is slow to schedule site visits, your builder doesn’t get paid on time, and work stalls. Before you commit to a lender, ask how quickly they process draw requests and what their average inspection turnaround is. One week is reasonable; three weeks is a problem.
Appraisal gaps
If the finished home appraises below expectations — because comparable sales dropped during construction or the plans were too ambitious for the neighborhood — you may face challenges converting to a permanent mortgage. Use conservative comps when estimating finished value and avoid over-improving relative to the surrounding market.
Contractor problems
A contractor who goes out of business or abandons the project mid-build is a lender’s worst nightmare (and yours). Vet contractors thoroughly: check license status through your state’s contractor licensing board, review their insurance, and ask for bank references. Some lenders also review contractor financials as part of their approval process.
Changes in your financial situation
With construction-only loans, your mortgage application comes after the build is complete. If your income drops, your credit score falls, or rates spike during that period, you may struggle to qualify for the end loan. This is one of the strongest arguments for choosing a construction-to-permanent structure instead.
How To Get a Construction Loan: Step by Step
1. Get your finances in order
Review your credit report and correct any errors. Pay down debt to improve your DTI. Build up your down payment reserve plus a contingency fund. Use New Silver’s construction loan calculator to estimate project costs and check how different loan amounts affect your monthly payments.
2. Choose your builder before applying
Most lenders want to see a signed contract or at minimum a letter of intent from your contractor. Search the NAHB’s directory of local home builders’ associations to find licensed contractors in your area. Get quotes from at least three builders before committing.
3. Research lenders
Not every lender offers construction loans. Options include national banks, regional banks and credit unions, and private lenders like New Silver. Compare rates, draw processes, inspection timelines, and how quickly they can fund. For investment projects, private lenders often move faster and have more flexible underwriting than banks.
4. Compile your documentation
Pull together your financial documents, builder credentials, architectural plans, budget breakdown, permits, and timeline. The more complete your file, the faster the approval process tends to go.
5. Get pre-approved
Pre-approval confirms your borrowing capacity before you finalize builder contracts or purchase land. It gives you a clear budget ceiling and signals to contractors that you’re a serious buyer.
6. Arrange builder’s risk insurance
Your homeowner’s insurance policy doesn’t cover a home under construction. You’ll need a builder’s risk policy (also called course of construction insurance) to protect the partially built structure against fire, theft, and weather damage. Some lenders require this before they will fund.
7. Close and begin the draw schedule
At closing you’ll sign final loan documents, confirm the draw schedule, and authorize the first disbursement. From there, construction begins and draws are released as each milestone is inspected and approved.
FAQ
In many cases, yes. If you own the lot free and clear, many lenders will credit its appraised value toward the down payment requirement. If there’s an existing mortgage on the land, the lender will factor in how much equity you actually hold. Confirm this with your specific lender before assuming it applies.
You’ll need to cover the overage out of pocket unless you negotiate a loan modification with your lender. This is why a contingency reserve of 10–15% is not optional, it’s a basic risk management tool for any construction project.
With conventional lenders, the approval process can take 45 to 60 days given the volume of documentation involved. Private lenders like New Silver can approve in 48 hours because they underwrite against the asset and the project rather than running a lengthy institutional process.
Not necessarily, but lenders will factor your existing mortgage payments into your DTI calculation. If carrying two housing costs pushes your DTI too high, you may need to sell first, or find a lender with a higher DTI tolerance.
Yes, and you should. The builder is not assigned by the lender. You select your contractor and bring them to the lender for approval. The lender evaluates whether they are sufficiently licensed and financially stable to complete the project.
Construction loans have fixed terms. If your project runs longer than the loan term allows, you’ll need to request an extension from your lender. Extensions are common but not automatic, expect additional fees and paperwork. Choosing a contractor with a strong completion record is the best way to avoid this situation.
Most conventional lenders want to see 680 or above. Some will go down to 620 for well-qualified borrowers with strong income and a large down payment. Hard money and private lenders often have more flexible credit requirements but compensate with higher rates.
Final Thoughts
Construction loans make it possible to build exactly the home you want — but they require more preparation, more documentation, and a higher tolerance for complexity than a standard mortgage. The borrowers who navigate them successfully tend to go in with a realistic budget (including a solid contingency buffer), a vetted contractor, and a clear sense of which loan structure fits their situation.
If you’re building as a primary residence, a construction-to-permanent loan is usually the cleanest route. If you’re an investor building to sell or hold, a private lender like New Silver can get you to funding significantly faster than a bank.
