When you dream of building your own home from the ground up, one of the most critical pieces of the puzzle is financing. A construction mortgage (or construction loan) can help turn that dream into reality. But unlike traditional home loans, construction mortgages come with unique requirements, timelines, and structures that are important to understand before you dive in.
What Is a Construction Mortgage?
A construction mortgage is a short-term loan designed to cover the cost of building a new home or completing major renovations. Instead of receiving a lump sum like with a traditional mortgage, the borrower receives funds in installments (called draws) as construction progresses.
Once the home is completed, the loan is either converted into a traditional mortgage (a process known as construction-to-permanent loan) or paid off entirely, depending on the loan terms.
How Does a Construction Mortgage Work?
Construction mortgages work in phases. Here’s how:
Pre-Approval & Planning
Before construction begins, you need detailed architectural plans, a builder contract, and a clear budget. The lender uses these to assess the loan risk.Draw Schedule
Funds are released in stages aligned with construction milestones (foundation, framing, roofing, etc.). Each draw typically requires an inspection to confirm progress.Interest-Only Payments
During construction, you usually pay only the interest on the drawn amount. This helps keep payments manageable while you’re still building.Conversion or Repayment
Once construction is complete, the loan may convert into a traditional mortgage with regular payments, or you may need to secure a new loan to pay off the balance.
Types of Construction Mortgages
1. Construction-to-Permanent Loan
A single loan that transitions into a permanent mortgage once construction ends.
Benefits: One closing, lower costs.
2. Construction-Only Loan
Short-term financing that must be paid off or refinanced at project completion.
Benefits: Flexibility in choosing long-term mortgage providers later.
3. Owner-Builder Loan
For borrowers acting as their own general contractor.
Requires experience or proof of competency in managing construction.

A down payment of 20% or more
A contingency reserve to cover overruns
