Construction Loans
Construction loans are short-term loans designed to finance the building or major renovation of a home or property, with funds released in stages as construction progresses. Unlike traditional mortgages, borrowers typically make interest-only payments during construction before the loan is either paid off or converted into a permanent mortgage.

What Is a Construction Loan?
A construction loan is short-term financing used to build a new home, complete a custom home financing project, or fund renovation financing. The lender does not release all funds at once. Instead, money is advanced through phases called draws, and borrowers often pay interest-only payments during construction on the amount that has been disbursed. When the project is complete, some loans refinance while others convert into a permanent construction mortgage automatically.

Types of Construction Financing
Short-term build financing with refinance after completion
This structure funds construction as a temporary build a house loan, usually with interest-only payments during construction. After the home is completed, the borrower refinances into a permanent mortgage.
Pros: Flexibility, ability to shop permanent financing later, potentially lower short-term costs.
Cons: Two closings, requalification risk, additional closing costs.
Best for: Experienced builders, investors, borrowers expecting future rate improvements.
One-time close that converts automatically
A construction-to-permanent loan uses one closing and then converts into a long-term construction mortgage once the project is complete.
Pros: One closing, simpler process, rate security, easier budgeting.
Cons: Less flexibility later, potential to lock into a higher long-term rate.
Best for: Primary residences and first-time custom home borrowers.
Rehab and remodel-focused financing
Renovation financing options may include FHA 203(k) and conventional renovation loans, depending on project scope and borrower profile.
Pros: Can finance purchase plus improvements, strong for value-add projects.
Cons: Documentation-heavy, contractor bid standards can be strict.
Best use cases: Older homes needing major updates, strategic repositioning projects.
Borrower serves as general contractor
Owner builder loan structures are possible in limited cases, but many lenders do not allow owner-builders due to higher project execution risk.
Raw land and improved lot financing
A land loan can fund raw or improved land, but lot financing is generally tougher than financing a completed home.
Traditional banks prefer completed homes because completed homes are easier to appraise, easier to sell, and have more stable collateral value.
Why Construction Loans Are Harder to Qualify For
A standard mortgage is secured by an existing property. A construction loan is funding something that does not fully exist yet. The lender is underwriting projected future value, timeline performance, and build execution quality. That is why construction loans usually have tighter standards than a typical home loan.
What lenders typically want to see
Why Builder and Borrower Experience Matters
Banks typically prefer licensed builders with a history of completed projects. First-time builders and owner-builders can still qualify in some cases, but they usually face stricter scrutiny and documentation standards.
First-Time Custom Home
Usually financeable with a strong builder and full documentation package, but underwriting is more conservative.
Experienced Builder
Prior successful projects can reduce risk perception and improve execution confidence.
Investor Spec Build
Can work well with proven timelines, strong reserves, and realistic exit strategy assumptions.
Major Renovation Project
Detailed scope, vetted bids, and contingency planning are critical for approval and budget control.
How Interest-Only Construction Payments Work
Construction loans typically charge interest only on funds already disbursed. As draw balances rise, monthly payment amounts often rise too. Draw schedules and delays directly influence total interest expense.
