The Core Difference
A construction loan disburses money in stages as you build. A traditional mortgage disburses the full amount once, at closing, for a home that already exists.
You cannot get a standard mortgage to build a house — there is no completed asset for the lender to appraise and secure the loan against. Construction loans solve this by releasing funds incrementally as the lender verifies progress, then typically converting to a standard mortgage once the home is complete.
Construction Loan vs Mortgage — 10 Categories Compared
| Category | Construction Loan | Traditional Mortgage |
|---|---|---|
| Purpose | Funds the building process | Funds the purchase of an existing home |
| Disbursement | Released in draws as construction milestones complete | Full amount disbursed at closing |
| Interest calculation | Interest-only payments on the amount drawn so far | Principal and interest from day one |
| Interest rate | Typically 0.5–1.5% higher than a traditional mortgage | Standard market rate for the loan type |
| Down payment | Typically 20–25% (sometimes higher for owner-builder) | As low as 3–5% with conventional financing |
| Loan term | Short term — 8 to 18 months during build | 15 or 30 years |
| Inspections | Required at each draw to verify completed work | One appraisal before closing |
| Approval requirements | Plans, specs, contractor qualifications, budget, builder contract | Income, credit, property appraisal |
| Closing costs | Often two sets of closing costs (construction + permanent loan) | One set of closing costs |
| Risk to lender | Higher — project could stall, go over budget, or fail to complete | Lower — asset already exists and is verifiable |
4 Types of Construction Loans
A single loan that converts automatically from construction financing to a permanent mortgage once the home is complete. One closing, one set of closing costs, simpler process.
A short-term loan that covers only the construction period. Once construction is complete, you refinance into a separate traditional mortgage — a second closing.
For borrowers acting as their own general contractor rather than hiring a licensed GC. Requires demonstrating construction experience and project management capability.
Government-backed loan programs that combine purchase or refinance with renovation or construction funding. Lower down payment requirements but more restrictions.
Frequently Asked Questions
What is the difference between a construction loan and a mortgage?
A construction loan funds the building process and is disbursed in stages (draws) as construction milestones are completed, with interest charged only on the amount drawn. A traditional mortgage funds the purchase of an existing home, with the full loan amount disbursed at closing and principal-and-interest payments starting immediately.
Do I need a construction loan to build a new home?
If you are financing the build rather than paying cash, yes — you need either a construction-to-permanent loan or a stand-alone construction loan. Traditional mortgages are designed for purchasing existing homes and do not accommodate the draw schedule and inspection requirements of new construction.
What down payment is required for a construction loan?
Construction loans typically require 20-25% down, higher than the 3-5% possible with some conventional mortgages. Owner-builder construction loans often require 25-30% down due to higher lender risk. FHA construction loan programs can require as little as 3.5% down but have additional restrictions.
Is a construction-to-permanent loan better than a stand-alone construction loan?
For most borrowers, construction-to-permanent loans are simpler and cheaper — one closing, one set of closing costs, and the permanent loan terms are locked in before construction starts. Stand-alone construction loans offer more flexibility to shop for the best permanent mortgage rate after construction, but require two closings and two sets of fees.
How does the draw schedule work on a construction loan?
A construction loan disburses funds in stages tied to completed construction milestones — typically foundation, framing, rough-in, drywall, finishes, and final completion. The lender requires an inspection at each draw to verify the work claimed to be complete actually is, before releasing the next payment. This protects both the lender and the borrower.
