A construction loan releases funds in stages tied to completed work, unlike a standard mortgage that pays out in one lump sum.
Most construction loans convert to a permanent mortgage once the home is complete, often called a construction-to-permanent loan.
Interest during construction typically applies only to funds actually drawn, not the full loan amount.
Working with a lender experienced in construction lending, alongside your builder, keeps the draw schedule realistic.
A construction loan finances a custom home build by releasing funds in stages tied to completed work, rather than paying out the full loan amount at once the way a standard mortgage does. Most construction loans convert automatically into a permanent mortgage once the home is finished, a structure often called a construction-to-permanent loan. This page explains how these loans work and what to expect during the process. This is general financial information, not financial advice, so working with a qualified lender on your specific situation remains essential.
How construction loans differ from standard mortgages
A standard mortgage pays out the full loan amount at closing because the home already exists. A construction loan works differently because the home does not yet exist, so lenders release funds progressively as construction reaches defined milestones, protecting the lender’s investment by verifying work is actually complete before releasing the next portion of funds. This staged approach means a construction loan requires more coordination between you, your lender, and your builder than a standard mortgage does.
How the draw schedule works
A construction loan’s draw schedule typically ties fund releases to specific completed milestones, such as foundation completion, framing completion, and various interior finishing stages. Before each draw, the lender typically sends an inspector to verify the claimed work is genuinely complete, then releases funds to cover that stage’s costs. Our custom home building pillar guide covers the typical construction sequence that a draw schedule generally follows.
Interest during construction
Interest on a construction loan typically applies only to the funds actually drawn at any given point, not the full loan amount from day one. This means your interest costs during construction start relatively low and increase as more of the loan is drawn down through the building process, an important distinction from a standard mortgage where interest applies to the full loan amount immediately.
Construction-to-permanent loans
Most residential construction loans are structured as construction-to-permanent loans, meaning the loan automatically converts into a standard mortgage once construction is complete, without requiring a second loan application and closing process. This structure simplifies financing considerably compared to older approaches that required separate construction and permanent financing with two closings, and it protects you from the risk of interest rate changes between the two phases in many loan structures.
What lenders typically require
Construction loan lenders generally want to see detailed plans and specifications, a signed contract with a licensed builder, and a realistic budget before approving financing. Our post on how to hire a contractor in Asheville covers verifying a builder’s license and qualifications, which matters not just for your own protection but often as part of a lender’s approval requirements as well.
Contingency and change orders under a construction loan
Because a construction loan ties funding to a specific budget and draw schedule, change orders or unexpected costs during construction require careful coordination with your lender, not just your builder. Understanding how your specific loan handles contingency funds and change order costs before construction begins prevents a funding gap mid-project. Our post on cost-plus versus fixed-price contracts covers how contract structure interacts with budget certainty, which matters directly for construction loan planning.
Working with both your lender and builder together
A smooth construction loan experience depends on close coordination between your lender and your builder, particularly around draw timing and inspection scheduling. Choosing a builder experienced in working with construction loans, who understands how to document completed milestones clearly for a lender’s inspector, helps keep your draw schedule moving without unnecessary delays.

Summary
A construction loan finances a custom home build by releasing funds progressively as construction reaches defined milestones, with interest typically applying only to funds actually drawn. Most residential construction loans convert automatically into a permanent mortgage once the home is complete, simplifying the financing process compared to older two-closing approaches. Lenders generally require detailed plans, a signed contract with a licensed builder, and a realistic budget before approving this kind of financing. Homeowners planning a custom build should discuss construction loan options with a qualified lender early in the planning process, alongside conversations with their builder.

Frequently Asked Questions
How is a construction loan different from a regular mortgage?
A regular mortgage pays out the full amount at closing since the home already exists. A construction loan releases funds progressively as construction reaches defined milestones, verified by a lender inspection before each draw, since the home is still being built.
Do I need two separate loans to build and then finance a custom home?
Usually not. Most residential construction loans are structured as construction-to-permanent loans, converting automatically into a standard mortgage once construction is complete, without requiring a second loan application and closing.
How does interest work during construction?
Interest typically applies only to funds actually drawn at any given point, not the full loan amount from day one. This means interest costs start relatively low and increase as more of the loan is drawn down through the building process.
What do lenders require to approve a construction loan?
Lenders generally want detailed plans and specifications, a signed contract with a licensed builder, and a realistic project budget. Verifying your builder’s license and qualifications, covered in our hiring guide, often matters for lender approval as well as your own protection.
How do change orders work with a construction loan?
Change orders or unexpected costs require coordination with both your lender and your builder, since the loan ties funding to a specific budget and draw schedule. Understanding how your particular loan handles these situations before construction begins prevents a funding gap mid-project.
