Construction loan lenders fall into three main groups — community banks and credit unions, specialty construction lenders, and a handful of larger national banks with construction divisions. Community banks and credit unions actually dominate this market because they hold loans on their own books rather than selling them, which gives them flexibility to underwrite construction projects that don’t fit standard mortgage rules. The biggest national banks (Chase, Wells Fargo, Bank of America) generally do less construction lending than people expect.
Construction loans differ from regular mortgages in three important ways: they’re short-term (typically 12–18 months during construction), they fund in draws tied to construction milestones rather than as a single lump sum, and they convert into a permanent mortgage upon completion. The Consumer Financial Protection Bureau publishes a clear plain-language explanation of how construction loans work, which is worth reading before you start your application.
The Three Lender Categories
| Lender Type | Typical Loan Size | Strength | Drawback |
|---|---|---|---|
| Community banks/credit unions | $200K–$2M | Local relationships, builder familiarity, portfolio flexibility | Limited geography, slower decisions |
| Specialty construction lenders | $300K–$5M+ | Construction expertise, faster builder relationships | Higher rates, less flexibility on terms |
| Large national banks | $500K+ (often jumbo) | Brand, product menu | Less construction focus, stricter rules |
For most owner-occupied builds in the $300K–$800K range, community banks and credit unions are the right first call.
How Construction Loans Actually Work
A typical construction loan has four phases:
1. Approval and setup. Borrower qualifies, lender approves, builder is vetted, construction budget is finalized. Closing happens before construction begins.
2. Construction phase (12–18 months). Funds release in draws tied to construction milestones — foundation poured, framing complete, mechanical rough-ins done, interior finishes. The borrower pays interest only on drawn amounts, not the full loan.
3. Conversion to permanent mortgage. Once construction is complete and the home passes final inspection, the loan converts to a standard 15- or 30-year mortgage. With a true construction-to-permanent loan, there’s only one closing (saves thousands in fees).
4. Permanent mortgage phase. Normal monthly principal-and-interest payments going forward.
The draw process is one of the most underappreciated parts. Each draw requires inspections and lender approval before funds release, which can create timing pressure with contractors expecting prompt payment.
What Construction Lenders Require
| Documentation | Why |
|---|---|
| Builder license and references | Confidence in the contractor |
| Construction contract | Defines scope, cost, timeline |
| Detailed budget | Line-item breakdown of costs |
| Architectural plans | What’s being built |
| Soil tests, surveys, permits | Risk verification |
| Larger down payment (20–25%) | Reduces lender risk during construction |
| Higher credit score (often 680+) | Compensates for construction risk |
The 20–25% down payment is meaningful. Many buyers comfortable buying an existing home at 5–10% down find construction loans require significantly more cash upfront.
Rates and Costs
Construction loan rates have two components:
| Phase | Typical Rate |
|---|---|
| Construction phase | Prime + 1–2% (variable) |
| Permanent loan after conversion | Locks at market rate at closing |
The construction-phase rate is often variable, tied to prime — one reason builders aim to keep timelines short. Closing costs run 2%–5% of the loan amount; construction-to-permanent loans avoid a second closing, saving $3,000–$7,000.
Where to Start Your Search
- Your local credit union if you’re a member — relationship pricing often beats banks
- Community banks in your area — especially ones known for working with local builders
- Specialty construction lenders — firms with construction-specific divisions
- National banks — only if your loan size or location requires them
The single best signal of a good construction lender is the answer to “how many construction loans does your branch close per year?” If the answer is “a handful,” look elsewhere.
Common Pitfalls
Underestimating the budget. Construction routinely runs 10%–20% over the initial estimate. Loans built tight to the original budget require change orders or additional funding.
Builder problems. A delayed builder stretches the construction phase, accruing more variable-rate interest. Vet your builder as carefully as your lender.
Permanent rate uncertainty. If your construction-to-permanent loan doesn’t lock the permanent rate at initial closing, you bear interest rate risk during construction. Ask explicitly.
Insufficient down payment. Many buyers underestimate the 20–25% requirement and end up unable to close.
Bottom Line
Construction loan lenders are mostly community banks, credit unions, and specialty firms. Start with local institutions where you already have relationships. Bring a strong builder, a buffered budget, and 20%–25% down. The process is more involved than a standard mortgage, but for a custom build, there’s no alternative path.
