Construction-to-Permanent Loans: What They Are and How They Work

Building a new home is exciting, but the financing side can feel confusing — especially if you have only purchased an existing home before. One of the most common questions we hear from customers is: “What is a construction-to-permanent loan, and how does it actually work?”

The short answer: a construction-to-permanent loan is a financing option that helps cover the cost of building your home and then converts into a traditional mortgage after construction is complete.

For many homebuyers, this type of loan can simplify the building process because it combines two important steps - construction financing and long-term mortgage financing - into one overall loan structure. However, it also comes with additional documentation, lender review, and planning requirements.

At Canbury Homes, we are not a lender, and we do not provide mortgage or financial advice. However, we do work with many banks and lending professionals throughout the homebuilding process, and we understand how important the right financing relationship can be.

When helpful, we can point customers toward lenders we have worked well with in the past - particularly those who are familiar with construction lending, understand the modular homebuilding process, and have shown a strong commitment to helping customers make sound financial decisions.

Our goal is not to steer you toward one specific bank or loan package, but to help you ask the right questions, better understand the process, and, when needed, connect you with professionals who can guide you through the financing side of building a new home.

What Is a Construction-to-Permanent Loan?

A construction-to-permanent loan, sometimes called a single-close construction loan or one-time close construction loan, is a loan designed for people who are building a new home.

Instead of getting one short-term loan to build the home and then applying for a second mortgage after the home is finished, a construction-to-permanent loan combines both phases into one overall loan process.

It generally works in two stages:

• Construction phase: The loan helps fund the construction of the home.

• Permanent mortgage phase: Once the home is complete, the loan converts into a traditional mortgage.

During construction, funds are not usually given out all at once. Instead, the lender releases money in stages, often called draws, as different parts of the project are completed.

Once construction is complete and the home meets the lender’s requirements, the loan transitions into a standard mortgage with regular monthly payments of principal and interest.

How Does a Construction-to-Permanent Loan Work?

While every lender has its own process, most construction-to-permanent loans follow a similar path.

1. You Get Pre-Qualified or Pre-Approved

The first step is usually speaking with a lender that offers construction financing. Not every mortgage lender offers construction-to-permanent loans, so it is important to work with someone familiar with new construction.

The lender will review many of the same items they would for a traditional mortgage, such as income, credit, debts, assets, employment history, and overall ability to repay the loan.

Because new construction has more moving parts than buying an existing home, lenders often require more documentation than they would for a standard home purchase.

2. You Develop a Project Budget and Home Plan

Before a lender can fully approve a construction loan, they need to understand what is being built, where it is being built, and how much the project is expected to cost. This may include:

• The home design or floor plan

• Site work estimates

• Foundation costs

• Utility costs

• Permitting information

• Builder contract or proposal

• Construction timeline

• Land information, if applicable

• Estimated total project cost

For modular homes, this may also include factory pricing, delivery costs, set costs, and other project-specific details. The more organized and complete the project information is, the smoother the financing process can be.

3. The Lender Reviews the Builder and Project

Construction lenders typically want to know that the project is realistic and that the builder is qualified to complete the work.

The lender may review builder credentials, insurance, licensing, experience, project documentation, and the proposed construction timeline. They may also order an appraisal based on the estimated completed value of the home.

This appraisal is different from an appraisal on an existing home because the appraiser is evaluating what the property is expected to be worth once the home is finished.

4. You Close on the Loan Before Construction Begins

With a construction-to-permanent loan, there is typically one closing at the beginning of the process.

This is one of the main differences between a construction-to-permanent loan and a construction-only loan. With a construction-only loan, you may need to close once on the construction loan and then close again later on a permanent mortgage.

With a construction-to-permanent loan, the goal is to handle both stages through one loan structure.

5. Funds Are Released Through Draws

During the construction phase, the lender releases funds in stages as work progresses. These payments are commonly called draws. For example, funds may be released after certain milestones are reached, such as:

• Site work completion

• Foundation installation

• Home delivery or set

• Rough framing or mechanical work

• Interior finish stages

• Final completion

The exact draw schedule depends on the lender, the builder, and the structure of the project. In many cases, the lender may require inspections before releasing each draw. This helps confirm that the work tied to that draw has been completed.

6. You May Make Interest-Only Payments During Construction

During the construction phase, many construction-to-permanent loans require interest-only payments based on the amount of money that has actually been drawn. This means your payment may start lower early in the project and increase as more funds are released.

Once construction is complete and the loan converts to a permanent mortgage, your payment typically shifts to a standard principal-and-interest mortgage payment.

7. The Loan Converts to a Permanent Mortgage

After the home is complete, the lender will usually require final documentation before the loan converts to the permanent mortgage phase.

This may include final inspections, certificate of occupancy, lien waivers, updated insurance, and confirmation that the project has been completed according to the approved plans.

Once the loan converts, it functions more like a traditional mortgage.

Construction-to-Permanent Loan Eligibility Requirements

Eligibility requirements vary by lender and loan program, so it is important to speak directly with a qualified mortgage professional. That said, construction loans often have stricter requirements than standard home loans because the lender is financing a home that does not exist yet.

Common requirements may include:

Strong Credit

Many lenders look for stronger credit profiles for construction financing than they might for some traditional mortgage products. A higher credit score can also help borrowers qualify for better terms.

Stable Income and Employment

Lenders want to confirm that you have reliable income and the ability to make payments during construction and after the loan converts to a permanent mortgage.

Acceptable Debt-to-Income Ratio

Your debt-to-income ratio, often called DTI, compares your monthly debt payments to your monthly income. Lenders use this calculation to help determine whether your future mortgage payment is affordable based on your overall financial picture.

Figuring out how much home you can comfortably afford should not feel like a guessing game. Our Home Affordability Calculator can help you estimate a realistic price range by factoring in your income, monthly debts, down payment, and interest rate — giving you a clearer starting point as you plan your new home project.

Down Payment or Equity

Construction-to-permanent loans often require a down payment. The amount varies by lender and loan program. If you already own the land, some lenders may allow your land equity or prior project-related costs to count toward part of your required contribution. This depends entirely on the lender’s guidelines.

Detailed Construction Plans

Unlike buying an existing home, a construction loan requires the lender to review what is being built. You should expect to provide detailed project information, including plans, specifications, budget, and timeline.

Approved Builder

Most lenders require the builder to be properly licensed, insured, experienced, and approved by the lender.

Appraisal Based on Completed Value

The lender will usually order an appraisal based on the projected value of the finished home. This helps the lender determine whether the loan amount is supported by the future value of the property.

Pros of Construction-to-Permanent Loans

Construction-to-permanent loans can be a helpful option for many people building a new home.

One Loan Process

One of the biggest benefits is simplicity. Instead of applying for a construction loan and then applying again for a permanent mortgage, you may be able to complete one loan process.

One Closing

A single-close loan may help reduce duplicate closing costs and paperwork compared to using separate construction and mortgage loans.

Interest-Only Payments During Construction

Many construction-to-permanent loans allow interest-only payments during the construction phase. This can help with cash flow while the home is being built, especially if you are also paying rent or carrying another housing payment.

Earlier Rate Certainty

Depending on the loan terms, you may be able to lock in certain mortgage terms earlier in the process. This can be helpful when interest rates are changing, although rate-lock terms vary by lender.

Clearer Path From Construction to Mortgage

Because the permanent mortgage is built into the structure of the loan, borrowers may have less uncertainty at the end of construction compared to needing to apply for a separate mortgage after the home is complete.

Cons of Construction-to-Permanent Loans

While construction-to-permanent loans can be convenient, they are not the right fit for every borrower or every project.

More Documentation

Construction loans require more paperwork than a standard mortgage. You may need to provide plans, budgets, builder information, insurance details, permits, and other project documents.

Stricter Qualification Requirements

Because construction loans involve more risk for the lender, borrowers may need stronger credit, a larger down payment, and more financial documentation.

Cost Overruns Are Still Possible

If construction costs increase beyond the approved loan amount, the borrower may be responsible for covering the difference. This is why it is important to build realistic budgets and include contingency planning.

Not Every Lender Offers Them

Construction-to-permanent loans are specialized products. Some lenders do not offer them, and others may only offer them under specific conditions.

Draw Schedules Can Add Complexity

The draw process adds another layer of coordination between the borrower, builder, lender, and inspectors. A clear draw schedule and good communication are important.

Construction-to-Permanent Loan vs. Construction-Only Loan

A construction-to-permanent loan is not the only way to finance a new build. Another option is a construction-only loan.

With a construction-only loan, the loan covers the building phase only. Once the home is complete, the borrower usually needs to pay off that loan with cash, refinance into a permanent mortgage, or obtain a separate mortgage.

With a construction-to-permanent loan, the loan is designed to convert into a long-term mortgage after the home is finished.

The right option depends on your financial situation, lender options, timeline, and long-term plans.

How to Apply for a Construction-to-Permanent Loan

If you are considering a construction-to-permanent loan, here are the general steps to expect.

Step 1: Talk With a Construction Lender Early

Before you get too far into design decisions, speak with a lender that regularly handles construction financing.

Ask whether they offer construction-to-permanent loans, what their general requirements are, and what documentation they will need from you and your builder.

This is where Canbury Homes can help. While we are not a lender, our team of building experts regularly works with banks and lending professionals who understand construction loans and modular home projects. If you are not sure where to begin, we can help point you toward lenders we have worked well with in the past so you can start asking the right questions.

Step 2: Understand Your Budget

It is important to understand not only the cost of the home itself, but also the full project cost. This may include:

• Land purchase

• Site work

• Septic or sewer

• Well or public water connection

• Foundation

• Utility connections

• Driveway

• Permits / Building Fees

• Engineering & Design Plans

• Modular home package

• House delivery and set

• Finish work

• Contingency funds

A common mistake is focusing only on the house price and underestimating the cost of preparing the land and completing the full project.

Choosing an experienced builder like Canbury Homes early in the process can help make budgeting easier. Our all-inclusive approach is designed to help customers look beyond just the home package and think through the broader project costs that may impact financing, planning, and overall affordability.

Step 3: Choose a Builder and Home Plan

Your lender will likely need to review both the builder and the proposed home before fully approving a construction-to-permanent loan.

This is why selecting the right builder and home plan early can be helpful. At Canbury Homes, we work with customers to organize key project details - including the home design, construction scope, site-related considerations, and other documentation that may be requested during the financing process.

Step 4: Gather Financial Documents

Your lender may ask for documents such as:

• Pay stubs

• W-2s or tax returns

• Bank statements

• Asset statements

• Debt information

• Credit authorization

• Land purchase agreement, if applicable

• Construction contract or proposal

• Home plans and specifications

Self-employed borrowers may need to provide additional documentation.

Step 5: Compare Lender Options

Because construction-to-permanent loans vary by lender, it is wise to compare more than one option. When comparing lenders, ask about:

• Down payment requirements

• Interest rate structure

• Rate-lock options

• Draw process

• Inspection requirements

• Closing costs

• Timeline

• Required contingency funds

• Whether land equity can count toward your contribution

• Builder approval requirements

• What happens if construction takes longer than expected

The lowest rate is not always the only factor. Experience with construction lending matters. You want a lender who understands the moving parts of a new home build, communicates clearly, and works diligently to help you make a sound financial decision.

Step 6: Complete Underwriting and Appraisal

Once your application and project documents are submitted, the lender will underwrite the loan. They will review your financial qualifications, the builder, the budget, the plans, and the appraised value of the completed home.

This stage may involve follow-up questions, document updates, or revisions to the budget.

Step 7: Close and Begin Construction

After final approval, you will close on the loan. From there, construction can begin according to the approved budget and draw schedule.

Step 8: Final Completion and Conversion

When the home is complete, the lender will confirm that final requirements have been met. Once the construction phase is complete, the loan converts to permanent mortgage repayment.

Questions to Ask Your Lender

Before choosing a construction-to-permanent loan, consider asking your lender:

• Do you offer construction-to-permanent loans for modular homes?

• Is this a one-time close or two-time close structure?

• What down payment is required?

• Can land equity count toward my required contribution?

• What credit score and DTI range do you typically require?

• How long is the construction period?

• What happens if the project takes longer than expected?

• How does the draw schedule work?

• Who approves each draw?

• Are inspections required before funds are released?

• Will I make interest-only payments during construction?

• When does the loan convert to a permanent mortgage?

• Is the permanent mortgage fixed rate or adjustable rate?

• Are there fees if the construction timeline changes?

• What documents will you need from my builder?

• Have you worked with modular home projects before?

Common Misunderstandings About Construction-to-Permanent Loans

“The lender gives me all the money upfront.”

Usually, no. Construction funds are typically released in stages as work is completed.

“It works just like a regular mortgage.”

Not exactly. A construction-to-permanent loan eventually becomes a regular mortgage, but the construction phase involves additional steps, documentation, inspections, and draw management.

“The house price is the full project cost.”

Not always. The full project cost may include land, site work, utilities, permits, foundation, driveway, finish work, and contingency funds.

“Every lender offers construction loans.”

No. Construction lending is specialized, and not all lenders offer it.

“If I qualify for a standard mortgage, I automatically qualify for a construction loan.”

Not necessarily. Construction loans may have stricter requirements and require more documentation.

Are Construction-to-Permanent Loans Used for Modular Homes?

Yes, construction-to-permanent loans may be used for modular homes, depending on the lender and loan program.

A modular home is built in sections in a factory and then delivered and set on a permanent foundation. From a financing perspective, the lender still needs to understand the full construction project, including the home package, site work, foundation, utilities, delivery, set, and final completion.

Because modular construction has a different payment and delivery structure than some traditional site-built projects, it is important to work with a lender who understands modular home construction.

This is one of the reasons Canbury Homes values strong relationships with experienced construction lenders. A lender who understands modular construction can often help make the process more clear, organized, and manageable for the customer.
