The construction-to-permanent loan, commonly called a C2P loan or construction-perm, combines the construction loan and the permanent mortgage into a single financing instrument that funds the project through construction and automatically converts to a long-term permanent loan at project completion. For developers who want to minimize the complexity of managing two separate loan closings, lock in permanent financing before construction begins, and avoid the refinancing risk that comes with a standalone construction loan, the C2P structure offers real advantages. Understanding how the C2P works, and where it differs materially from a separate construction loan and permanent financing combination, is essential knowledge for any developer financing ground-up construction.
How the C2P Structure Works
In a C2P loan, the lender provides a single commitment covering both the construction phase and the permanent phase. During construction, the loan functions like a standard construction loan: funds are advanced on a draw basis as construction progresses, interest accrues on outstanding balances, and the monitoring and draw inspection process functions the same as on any construction loan. At project completion, when the certificate of occupancy is issued and, for income-producing properties, when a specified occupancy threshold is reached, the loan converts from the construction phase to the permanent phase.
The conversion is administrative rather than transactional. The developer does not need to refinance, pay new closing costs for a new loan, or qualify with a different lender at a different rate environment. The loan simply transitions from construction-phase terms to permanent-phase terms that were established at the original closing.
This is the C2P’s primary advantage: rate certainty and structural simplicity. A developer who closes a C2P in a favorable interest rate environment and builds over 18 months knows exactly what their permanent financing rate will be when the project stabilizes, even if interest rates have moved materially during the construction period.
C2P vs. Standalone Construction Loan: The Key Differences
The alternative to C2P financing is a standalone construction loan that the developer refinances into permanent financing at project completion. This two-step approach is more common for large commercial and multifamily projects, the construction loan closes with one lender (or a bank group), and the permanent loan closes with a different lender (often an agency lender like Fannie Mae or Freddie Mac, a life insurance company, or a CMBS lender) after the project stabilizes.
The standalone two-step approach offers advantages that the C2P does not: flexibility to select the best permanent lender at stabilization based on market conditions at that time, ability to use agency financing (which C2P products typically can’t access because agency programs don’t fund the construction phase), and potentially lower permanent loan rates if the market improves during construction.
The tradeoffs: refinancing risk (if rates rise or the credit market tightens during construction, permanent financing may be more expensive or less available than anticipated), two sets of closing costs, and two qualification processes, one for the construction lender at origination and one for the permanent lender at stabilization.
Where C2P Financing Is Most Common
C2P financing is most commonly used for smaller commercial projects and owner-occupied commercial real estate, the product types served by SBA 504 financing, community bank construction programs, and the credit union construction lending programs that many small business owners use. For these borrowers, the simplicity of a single loan closing, a single lender relationship, and a defined permanent loan from the start is worth the tradeoff of less flexibility on permanent financing terms.
For large multifamily development, the product type that accesses agency financing through Fannie Mae’s multifamily programs or Freddie Mac’s multifamily programs, C2P financing is less common because the agency programs’ underwriting requirements and loan sizes don’t typically accommodate the construction phase in a single instrument. These projects use standalone construction loans and refinance into agency permanent financing at stabilization.
The Rate Lock Question
One of the most discussed questions in C2P financing is how the permanent loan rate is locked. Rate lock options vary by lender and loan program:
Lock at closing. Some C2P programs allow the developer to lock the permanent loan rate at the construction loan closing, providing certainty for the full term from closing through permanent loan maturity. This option is valuable in rising rate environments, a developer who locks at 6% at closing is protected if rates reach 8% by the time the project stabilizes. The cost of this protection is that the developer is also locked in if rates fall during construction.
Lock before conversion. Other programs allow a rate lock window as the project approaches stabilization, typically 60 to 90 days before the conversion date. This approach provides less certainty during construction but allows the developer to benefit if rates decline.
Floating to fixed at conversion. Some C2P products use a floating rate during construction that converts to a fixed rate at conversion, with the fixed rate determined by market conditions at conversion. This approach provides no rate certainty during construction but may offer a lower all-in rate if the construction period is short and market conditions are favorable.
Qualifying for C2P Financing
C2P qualification requires demonstrating creditworthiness for both the construction phase and the permanent phase at origination, the lender is making a commitment that covers both phases simultaneously. The underwriting evaluates the project’s economics (pro forma, comparable rents or sale values, absorption assumptions), the developer’s experience and financial strength, and the construction program’s credibility (GC qualifications, construction budget adequacy, schedule achievability).
Developers evaluating construction-to-permanent financing should compare the rate certainty and structural simplicity of the C2P structure against the flexibility and potentially lower permanent rates of a two-close approach, anchored to their specific project’s timeline and likely permanent lender options.
