Ground-Up Construction Loans: How to Finance Your Dream Home From the Foundation Up

Jun 17

Building a custom home is exciting, but financing it works very differently than buying an existing house. A ground-up construction loan pays for the build in stages instead of handing you one lump sum. Here is how it works, whether you can buy land now and build later, how long the process takes, how funding is released, and what documents you will need.

What Is a Ground-Up Construction Loan?

A ground-up construction loan finances the actual construction of a new home, starting with raw or vacant land and following the project through to a finished, move-in ready house. Unlike a traditional mortgage, the lender does not release the full loan amount upfront. Instead, funds are paid out in stages as the home gets built.

Many lenders offer this as a one-time close loan. That means the construction financing and the permanent mortgage are combined into a single loan with a single closing, rather than two separate loans and two separate sets of closing costs.

Why a One-Time Close Loan Matters

One closing, one set of closing costs. You are not paying to close twice, once for construction and again to refinance into a permanent mortgage.
One approval and one credit pull. Your financing is underwritten once at the start, rather than requalifying after construction ends.
One rate, locked early. Your permanent mortgage rate is set at the initial closing. Some lenders, including UWM, also offer a float-down option, so if rates improve during the build, you can lock in the lower rate before your loan converts to permanent financing.
Automatic conversion. Once the home is complete, the loan modifies into a standard mortgage without a second closing or new appraisal process.

How the Loan Is Funded: The Draw Schedule

Construction loans do not pay your builder in one check. Instead, the loan is funded through a draw schedule tied to completed stages of work.

How Draws Work

The builder completes a stage of construction, such as the foundation, framing, roofing, or interior finishes.
An inspector confirms the work matches the approved plans and budget.
The lender releases that portion of the loan, called a draw, directly to the builder.
The next phase of construction begins, and the process repeats until the home is finished.

During the build, most loans require interest-only payments, and interest only accrues on the funds that have actually been drawn, not the full loan amount. This keeps monthly costs manageable while the home is under construction. Many programs, including UWM's, are built around an eleven-month maximum build period, with an additional one-month modification window as the loan converts to permanent financing.

Can You Buy Land First and Build Later?

Yes. There are two common paths, and the right one depends on your timeline.

Buying Land and Building Right Away

If you already own your lot, or you purchase it as part of the same transaction, the value or equity in that land can typically count toward your down payment or borrower contribution on the construction loan. This can meaningfully reduce your out-of-pocket cash needed at closing.

Buying Land Now, Building Later

If you are not ready to build immediately, some lenders allow a separate land loan first, with the option to roll any remaining balance into a construction loan once you are ready. Land loans typically require a larger down payment, often in the 15% to 20% range, along with strong credit. Keep in mind that most construction loan programs are not designed for indefinite land banking. Many lenders expect construction to begin within a set window, commonly within a year or two of purchasing the land, so this path works best if you have a realistic build timeline in mind rather than an open-ended one.

Either way, owning your land outright before applying for construction financing is often viewed favorably by lenders. It shows equity and commitment to the project, which can help with approval and terms.

How Long Does It Take to Get a Construction Loan?

Timelines vary based on how complex your project is and how quickly your documentation comes together.

Loan approval alone typically takes 3 to 5 weeks.
Building with lender-approved, standard plans can close in as little as 3 to 6 weeks.
Building on land you already own with complete plans usually takes 4 to 8 weeks.
Fully custom builds with new permits or complex sites can take 6 to 12 weeks or longer.
One-time close loans overall generally close in 45 to 60 days, though more complex projects can extend to 75 days or more.

The construction phase itself is separate from the closing timeline. Once the loan closes and the build begins, the construction period itself commonly runs 11 to 12 months, though this depends heavily on your builder, permitting, and project size.

What Documentation Do You Need?

Construction loans require more documentation than a typical mortgage because the lender is underwriting both you and the project.

Borrower Documentation

Standard income and asset documentation, such as pay stubs, tax returns, and bank statements.
Credit history and, in most cases, a minimum credit score threshold.
Proof of funds for your down payment and reserves.

Project Documentation

Architectural plans and specifications, signed off by the design professional.
A detailed, line-item construction budget covering both hard costs, like materials and labor, and soft costs, like permits, engineering, and legal fees.
A fixed-price construction contract with your builder that includes a start date, completion date, and payment or draw schedule.
Proof of land ownership or purchase contract, if the land is not already owned.

Builder Documentation

Current contractor license.
Proof of general liability insurance.
A track record of completed projects, sometimes with references.

Gathering this paperwork early is the single biggest way to keep your approval and closing timeline on track. Incomplete builder documentation or unapproved plans are among the most common causes of delay.

Bottom Line

A ground-up construction loan lets you finance your dream home from raw land to a finished house, with funds released in stages as work is completed. Choosing a one-time close option, like the program offered through UWM, simplifies the process into a single closing, a single rate lock, and a single approval, rather than juggling separate construction and permanent loans. Whether you already own your land or are planning to purchase it as part of the process, working with your lender and builder early to line up plans, budgets, and documentation is the best way to keep your build on schedule.
