Construction Loan Basics: How to Finance Your Building Project
Contents
Building a home for yourself from the ground up sounds exciting right up until you think about all the costs involved: land, permits, foundation, framing, finishes... And don’t forget about all the surprise expenses you’ll have to manage, too.
Commercial and residential construction loans are lifesavers for projects facing funding gaps or sudden budget cuts. You’d be surprised to know how much of the real estate market would not exist today if not for a bit of timely financial support.
But how do construction loans work in the real market? This article explores the main principles, requirements, and types of construction loans to help you make the best choice for you or your business.
What Is a Construction Loan?
A construction loan is a short-term financing plan that you can apply for to build (new construction loans) or, sometimes, to complete or heavily renovate a property (mid-project/renovation loans). Sounds just like a mortgage, but the two are actually quite different.
A mortgage allows you to buy an already-finished house in installments. A home construction loan is a “borrowed budget” for finishing a real estate project or even starting one from scratch. Construction loans often use checkpoint funding, which allows the lender to manage risk better because the “collateral” is literally turning into a house in real time. In simple terms, you get access to the next part of the loan only once you complete a certain percentage of the project.
What Costs Are Covered by a Construction Loan?
Most residential and many commercial construction loans cover both hard costs (e.g., physical construction) and soft costs (e.g., paperwork and professional services). Depending on your situation, you can expect to receive loan compensation for:
- Land purchase or land payoff (if not already owned).
- Materials and labor (e.g., paying builders or contractors, hiring subcontractors, etc.).
- Permits and fees (e.g., local permits, inspections, sometimes impact fees, etc.).
- Engineering and project planning costs (often as part of the approved budget).
- Contingency reserves (buffer for mid-project changes or price spikes).
How Do Construction Loans Work?
The main thing to know about construction loans is that you won’t get a bag of money on day one. Instead, you’ll receive the loaned funds according to an individual draw schedule after the completion and verification of the project’s phases and milestones.
For example, let’s say you get a loan for setting your building’s foundation. Once the work is completed and successfully inspected, you can get a loan for completing the framing. After that, you can deal with all the rough-ins, then with finishes and decor, and so on.
Here’s how the process looks in detail:
- You submit a request for a budget and agree to a loan timeline.
- Once one of the milestones outlined in the project timeline is reached, you can make another draw request.
- The lender inspects your results (and will ask you to address any issues they find).
- The lender then disburses another round of loaned funds (commonly to the building contractor rather than the borrower).
- As a borrower, you usually make interest-only payments on the funds you draw, not the full approved loan amount.
Certain loans can be converted into a standard mortgage upon the project’s completion (construction mortgage loans/construction-to-permanent loans). Others may require you to pay off the construction loan with a separate mortgage in two closings. You can find more about the types of construction loans below.
Construction Loans vs. Traditional Mortgages
To sum up, construction and mortgage loans are similar in nature but differ in several crucial ways:
| Construction loans | Mortgages |
|---|---|---|
Purpose | To finance a new or ongoing building construction project | To buy a completed home |
Funding | Loaned funds are disbursed in draws at each stage of the project | A one-time loaned fund is provided for a certain period |
Payments | Usually require interest-only payments during construction | Require immediate principal plus interest repayments, sometimes a down payment too |
Qualification | Lenders evaluate both your financial capabilities and your project (plans, builder credentials, etc.) | Lenders only evaluate your financial capabilities (budget, credit score, etc.) |
Construction Loan Rates
Construction loans rates are variable and can fluctuate based on the prime rate. However, they are usually higher compared to regular mortgage rates. The average interest rate for a construction loan ranges from 7% to 7.21%, while the rates for a fixed 30-year mortgage start at 6%. Here are some factors that can influence the cost of your construction loan:
- Your credit score and your debt-to-income (DTI) profile.
- Whether you can provide land for the project.
- Project risks, namely its complexity, location, timeline, volatility of materials involved in the construction, etc.
- Experience and quality of documentation of the contracted builders.
- Loan type — is it construction-only or construction-to-permanent?
Delays can double the loan rates due to extended rent and additional months of variable interest. Also, keep in mind that construction business loans tend to be more expensive than construction home loans due to increased scale.
Construction Loan Requirements
To get approved for a construction loan, you must meet the following requirements:
- Credit score: Usually, you’ll need at least 680–700, but it depends on the lender.
- Income verification and low DTI: The lender needs proof that you can handle payments while also managing your current housing costs.
- Down payment: You will have to make a down payment of up to 20% of the loan, which is notably higher than a typical mortgage down payment.
- Builder approval: You will need well-experienced, licensed builders with proper credentials and good references who are ready to sign a contract with you.
- Project documentation: You must prepare and present construction plans, the project’s timeline, and the estimated budget.
- Insurance planning: The lender will often ask for additional protection from potential issues and risks, so insurance is usually required as well.
Types of Construction Loans
Before applying for one, you should first figure out the types of construction loans you can get.
Construction-to-Permanent Loan
This kind of loan funds your construction, and is then converted into a long-term mortgage once the home is complete. This option is great for getting predictable funding from the start. In certain cases, it may also allow closing both the construction and mortgage loans in one payment.
Construction-Only Loan
This loan type covers only the construction phase. What this means in practice is that when the construction ends, you must pay the loan off. It’s an optimal choice if you want to build a house first, and then consider available mortgage options (which may or may not improve in the future).
Renovation Loan
If you’re not building from scratch, a renovation loan can help you invest in an older property and upgrade it. For example, you can submit for:
- FHA 203(k) — an insured renovation loan with contingency reserves.
- Fannie Mae Smith Renovation’s loan — bundles of renovation loans with different financing plans.
Owner-Builder Construction Loan
Experienced builders managing their own projects may apply for owner-builder construction loans. In this case, the lender allows the borrower to act as the builder, thereby eliminating the need for a third-party contractor. This option, however, is usually available only to licensed builders with a proven track record.
How to Get a Construction Loan
Getting new construction loans is easy in our day and age, but we strongly recommend that you still do it step-by-step:
- Get a preapproval for a loan (if available) to see your budget limits.
- Look for contractors and locate a licensed builder that fits your needs.
- Compare available construction loans rates and offers.
Pick a lender and submit the following documentation:
- Builder contract;
- Plans;
- Financial docs;
- Assets;
- Employment;
- Insurance.
- Complete underwriting and appraisal.
- Finalize the loan and begin construction.
Pros and Cons of Construction Loans
Pros
- Flexibility: Construction loans allow you to start the project on your own terms.
- Equity-building potential: Property can increase in value over time, sometimes exponentially, making construction loans a great investment.
- Controlled disbursement: Loan draws help combat overspending.
Cons
- Higher interest rates: Construction loan rates are higher than average due to the risks of investing in an unfinished property.
- Stricter approval process: Lenders underwrite both borrower and project documentation.
- Delays and overruns: If you go over budget, you may need to pay out of pocket.
Conclusion
Construction loans are most rewarding if you carefully manage your venture. It’s crucial to calculate not just the loan amount, but the right insurance coverage and protection plan for the project. Make sure to consult lenders, review their offers, and submit a construction loan application only once you’re sure of what you’re doing.
FAQ
Can I get a construction loan with bad credit?
Yes, but bad credit limits your choice of lenders and guarantees worse loan terms. Most lenders look for a credit score of around 680+, but some may be willing to go lower. In the US, borrowers with lower scores sometimes qualify through government-backed options (e.g., FHA programs can allow a 500 score).
How much down payment do I need for a construction loan?
On average, expect to pay about 20% of the loan upfront, but the sum can reach 25%–30% depending on the lender and estimated project risks. Some programs may allow lower down payments, but they’re rarely available for ground-up construction.
How long does it take to get approved for a construction loan?
A common timeline is about 30–45 days if your file is complete in time for lenders to underwrite everything. In practice, many borrowers wait for up to 90 days due to appraisals, plan revisions, and builder approvals.
