If you're building a custom home rather than buying an existing one, you need a construction loan — and ideally, a construction-to-permanent (C2P) loan that automatically converts to your long-term mortgage when the home is complete. This single-close structure saves time, money, and the risk of qualifying again after construction. Here's how it works.
Construction Loans vs. C2P Loans
Stand-alone construction loan: A short-term (12–18 months) loan covering only the build period. When construction is complete, you close on a separate permanent mortgage, paying two sets of closing costs and qualifying twice.
Construction-to-permanent (C2P) / One-Time Close: You close once — at the start of construction — and the loan automatically converts to a traditional mortgage (FHA, VA, USDA, or conventional) upon completion. One closing, one set of costs, one qualification process.
C2P is almost always the better choice unless you expect interest rates to drop significantly during the construction period (in which case standing alone lets you lock a lower permanent rate later).
How the C2P Loan Works
Phase 1 — Construction:
- You close on the C2P loan before construction begins
- Loan funds are disbursed in draws to the builder as construction milestones are completed
- During construction, you typically pay interest-only on disbursed amounts
- The lender inspects completed work before each draw release
Phase 2 — Modification/Conversion:
- When construction is complete and a certificate of occupancy (CO) is issued, the loan automatically converts to the permanent mortgage
- No second closing, no new underwriting, no new appraisal (in most cases)
- Regular P&I payments begin
Eligible Loan Types for C2P
FHA One-Time Close: Available for custom builds on land you own or purchase simultaneously. 3.5% down based on the finished home's appraised value. Available in Colorado and Florida.
VA One-Time Close: Zero down for eligible veterans building a custom primary residence. Very powerful — the only zero-down construction financing available.
USDA One-Time Close: Available in eligible rural areas (much of rural Colorado and Florida qualifies). Zero down for income-qualifying borrowers.
Conventional C2P: Fannie Mae and Freddie Mac have guidelines for construction-to-permanent financing. Typically 5–20% down depending on the lender's overlay and LTV.
Jumbo C2P: For custom homes above conforming limits (common in Colorado mountain counties and Florida luxury markets). Portfolio lender products; larger down payments.
Qualification Differences From Standard Mortgages
Land: If you already own land, its equity can serve as the down payment. If purchasing land simultaneously, it's included in the total loan.
Builder approval: The lender must approve your builder — they're underwriting both you and the contractor. Builders need a valid license, proof of insurance, and sometimes a track record of completed projects.
Appraisal method: Instead of appraising an existing home, the appraiser reviews your plans, specs, and lot location to generate an "as-completed" value. Your loan is based on this estimated future value.
Interest reserves: During construction, your monthly interest payments (on the portion of the loan disbursed) may be built into the loan as reserves — so you're not making construction-phase payments out of pocket in some structures.
Typical Timeline
| Stage | Timeline |
|---|---|
| Pre-approval and lender selection | 1–2 weeks |
| Appraisal (plans/specs review) | 2–3 weeks |
| Loan approval and closing | 2–4 weeks |
| Construction phase | 6–18 months (varies) |
| Final inspection and CO | 2–4 weeks after completion |
| Conversion to permanent loan | 30–45 days after CO |
Colorado Construction Considerations
Mountain lots: Building in Eagle, Summit, Pitkin, or Routt Counties introduces significant complexity — steep terrain, high elevation, remote utilities (well, septic vs. municipal), and builder scarcity. C2P lenders serving mountain markets are fewer than in the Front Range.
Wildfire mitigation requirements: New construction in Colorado's mountain counties must meet wildfire defensible space standards. Some lenders require proof of compliance before funding final draws.
Spec homes (not full custom): Many "new construction" purchases in communities like Erie or Windsor are spec homes — builder owns the lot, builds the home, buyer purchases the finished product. These don't require a C2P loan — you get a standard purchase loan when the home is complete.
Florida Construction Considerations
Hurricane-resistant construction: Florida's building code requires wind-resistant construction (impact windows/doors or shutters, reinforced roof connections). These requirements add construction cost but also reduce your insurance premiums — factor into your budget.
Septic and well: Rural Florida construction often requires well and septic installation — significant cost ($10,000–$20,000+) that must be in your construction budget.
USDA One-Time Close rural Florida: Strong USDA eligibility in Citrus, Hernando, Marion, and north-central Florida — zero-down custom construction in rural areas is genuinely available.
FAQ
Can I act as my own general contractor? Most C2P lenders require a licensed general contractor. Owner-builder loans exist but are rare and have stricter requirements.
What if construction goes over budget? Cost overruns are your responsibility. The lender does not automatically advance additional funds. Contingency reserves (10–15% of build budget) are essential.
Can I lock my rate during construction? C2P loans handle rate lock differently by lender. Some lock at close; some lock at conversion. If rates are volatile, understand your lender's rate lock structure before choosing.
What if my builder goes out of business during construction? A nightmare scenario — this is why lender approval of the builder matters. Ensure your contract includes provisions for this scenario; some lenders require completion bonds.
