How Construction Loans Work in 2026: A Complete Guide

If you’ve ever dreamed of building your own home, you’ve probably discovered something pretty quickly:

Construction loans can sound complicated.

Between buying land, choosing a builder, permits, inspections, loan draws, and hearing terms like construction-to-permanent or one-time close, it’s easy to feel overwhelmed.

The good news is that once you understand how the process works, it’s actually much more straightforward than most people expect.

I talk with people about construction financing fairly regularly, and most of the questions I hear are the same:

  • How much money do I need?
  • Can I finance the land?
  • Do I have to refinance after construction?
  • How does the builder get paid?

Let’s walk through it.

What Is a Construction Loan?

A construction loan is a mortgage specifically designed to finance the building of a new home.

Unlike buying an existing home, where the seller receives all of the money at closing, a construction loan releases funds over time as your home is being built.

This allows the lender to verify that construction is progressing before additional funds are released.

Not All Construction Loans Are the Same

One thing many buyers don’t realize is that there are different types of construction loans.

The two most common are two-time close construction loans and one-time close construction-to-permanent loans.

Two-Time Close Construction Loans

With this type of loan, you typically:

  • Obtain a construction loan.
  • Build the home.
  • Apply for a brand-new mortgage once construction is complete.

The permanent mortgage is used to refinance and pay off the original construction loan.

That means a second closing, likely additional closing costs, more paperwork, and potentially another round of qualifying.

One-Time Close Construction-to-Permanent Loans

This is the type of construction financing I personally work with.

Instead of obtaining two separate loans, everything happens under one loan.

Once construction is complete, the loan automatically converts into your permanent mortgage.

There is no second loan application and no refinance simply because construction is finished.

Personally, I think this is one of the biggest advantages of this type of program.

Step 1: Buying the Land

Every project starts somewhere.

Some buyers already own their land. Others need financing to purchase it.

Depending on the loan program, you may be able to:

  • Finance the land purchase.
  • Use land you already own as part of your equity.
  • Pay off an existing land loan as part of the construction financing.

Every lender handles this a little differently, which is why it’s important to discuss your situation early in the process.

Step 2: Choosing a Builder

One of the biggest parts of the process is selecting your builder.

Most lenders require builders to go through an approval process before construction begins.

Typically, they’re looking for things such as:

  • Proper licensing
  • Insurance
  • Experience building similar homes
  • Recent construction history

The goal isn’t to make the process harder. It’s simply to reduce the risk that construction gets delayed or left unfinished.

Step 3: Finalizing Your Plans and Budget

Before construction financing can close, you’ll generally need:

  • House plans
  • Plat map
  • Building contract
  • Construction budget
  • Building permits or evidence that they are in process

This becomes the roadmap for the entire project.

What Is a Construction Contingency?

Many construction loans include a contingency reserve, typically around 5% to 10% of the construction budget.

This provides extra room in the budget for unexpected costs. If the contingency isn’t used, you simply don’t borrow that money, and it does not become part of your final loan balance.

How Builder Draws Work

This is probably the biggest question I get.

The builder doesn’t receive all of the construction money on day one.

Instead, money is released in stages called draws.

For example, draws may be requested after milestones such as:

  • Foundation completion
  • Framing completion
  • Roof installation
  • Drywall completion
  • Interior finishes
  • Final completion

As work is completed, the builder requests a draw.

The lender verifies that the work has been completed, often through an inspection, and then releases the appropriate funds.

Depending on the loan structure, those funds may be sent directly to the builder or to the homeowner for payment to the builder.

This process continues until the home is complete.

What Are Payments Like During Construction?

Another pleasant surprise for many buyers is that you generally aren’t making full mortgage payments while the house is being built.

With many construction-to-permanent loans, you’ll make interest-only payments during construction.

Your loan does not begin at its full balance. As builder draws are released, your outstanding loan balance gradually increases.

Because you’re only paying interest on the amount that has actually been disbursed, your payment generally increases gradually throughout construction.

Once construction is complete, the loan automatically converts into a traditional principal-and-interest mortgage based on the final amount borrowed.

What Can Be Included in a Construction Loan?

Many buyers assume they’re only financing the house itself.

Often, that’s not the case.

Depending on the loan program, construction financing may also include items such as:

  • Well installation
  • Septic system
  • Driveways
  • Landscaping
  • Solar panels
  • Shops
  • Swimming pools
  • Retaining walls
  • Site preparation

Every lender has different guidelines, but construction financing can often include much more than just the home itself.

Credit Score and Down Payment Requirements

Construction loans typically have somewhat stricter qualification requirements than traditional purchase loans.

While every lender is different, you’ll often see:

  • Higher minimum credit score requirements
  • Larger down payment requirements
  • Cash reserve requirements

For example, the construction loan program I work with generally requires a minimum credit score between 680 and 720, depending on the down payment and loan amount.

It may allow financing up to 90% loan-to-value for qualified borrowers. That could mean approximately 10% down, or financing up to 90% of the completed value when land is already owned.

Programs vary, so it’s always worth discussing your specific situation with a lender.

What If I Already Own a Home?

This comes up fairly often.

Some buyers plan to remain in their current home while construction is taking place and then sell it after the new home is finished.

Normally, the existing mortgage payment must be included when determining how much the borrower qualifies for.

However, some lenders, including the program I work with, may be able to use projected rental income from the current home to help offset that mortgage payment.

The projected rent must be supported by the lender’s guidelines and documentation, such as an acceptable market-rent estimate. This may be possible even though the borrower continues living in the home during construction and does not plan to rent it until moving into the newly completed home.

Not every lender offers this option, but it’s another reason construction financing isn’t always one-size-fits-all.

Is Building More Complicated Than Buying?

Honestly?

Yes.

There are simply more moving pieces.

But that doesn’t mean it’s something to be afraid of.

A good builder, an experienced lender, and clear communication make an enormous difference.

Most buyers only build a home once or twice in their lifetime. It’s perfectly normal to have questions.

Frequently Asked Questions

Can I finance the land?

Often, yes. Depending on the loan program, you may be able to finance the land purchase as part of the construction loan.

If you already own the land, the construction loan may be used to pay off an existing land loan. In many cases, equity you have in the land can also count toward your required down payment or overall project equity.

Do I make full mortgage payments during construction?

Typically, no. Many construction loans require interest-only payments during the construction phase before automatically converting into a regular principal-and-interest mortgage once the home is complete.

Can I finance a shop, well, or septic system?

Often, yes. Many construction loans allow improvements such as shops, wells, septic systems, driveways, landscaping, solar panels, and swimming pools to be included if they are part of the approved project and meet the lender’s guidelines.

Can I be my own builder?

Some lenders allow owner-builder construction loans, while others require you to use an approved professional builder. The construction loan program I work with requires an approved builder.

If something prevents an owner-builder from completing the project, it can be difficult to find someone willing to step in and finish the home within the original budget and timeline. Working with an approved builder helps reduce that risk for everyone involved.

Can I build a tiny home or barndominium?

It depends on the lender. Some lenders finance unique properties such as barndominiums, tiny homes, or container homes, while others do not.

These properties can be more difficult to finance because there may be fewer comparable sales available for the appraisal. The construction program I work with does not currently finance tiny homes or barndominiums.

If you’re planning a unique build, it’s best to discuss it with your lender before purchasing land or finalizing your plans.

How long does construction usually take?

Every project is different, but many custom homes take approximately 8 to 15 months, depending on the size of the home, weather, permitting, material availability, and contractor schedules.

What credit score do I need for a construction loan?

Requirements vary by lender, but construction loans often have higher credit score requirements than traditional purchase loans.

Expect to need a credit score of 680 or higher. The construction loan program I work with generally requires a minimum score between 680 and 720, depending on the loan amount and down payment.

Do construction loans have higher interest rates?

Rates vary by lender and loan structure, but construction-to-permanent loan rates may be similar to conventional mortgage rates.

Your exact rate will depend on factors such as your credit, loan amount, down payment, market conditions, and the specific construction program.

Do I have to refinance when construction is finished?

That depends on the type of construction loan.

With a two-time close loan, you generally need to obtain a new permanent mortgage to refinance and pay off the construction loan.

With a one-time close construction-to-permanent loan, the loan automatically converts into the permanent mortgage after construction is completed.

Final Thoughts

Building a home can seem intimidating at first, but once you understand how the process works, it becomes much easier to see how all the pieces fit together.

Every construction project is different.

Every lender has different guidelines.

Every builder has a different process.

And every buyer has different goals.

The most important step is having a conversation early in the process so you understand what’s possible before purchasing land or signing a building contract.

Whether you’re just starting to look for land or already have building plans in hand, talking with a lender early can help you understand your financing options, avoid common surprises, and put together a plan that fits your goals.
