C-PACE vs bridge loan
These are usually presented as alternatives. They are better understood as tools for different jobs — and on a lot of projects the right answer is both, in the same capital stack.
| C-PACE | Bridge loan | What it means | |
|---|---|---|---|
| Cost | 5–8% fixed | Typically 9–14%, usually floating | C-PACE pricing tracks roughly the 10-year Treasury plus about 3% |
| Term | Up to 30 years | 6 months to 3 years | C-PACE term is matched to the useful life of the improvements |
| Amortisation | Fully amortising | Usually interest-only with a balloon | A bridge loan ends in a refinance or a sale, by design |
| Security | Property tax assessment | Mortgage on the property | The assessment sits ahead of the mortgage in priority |
| Recourse | Typically none | Frequently recourse or partial | Confirm with the specific provider — this varies |
| On sale | Transfers to the buyer | Must be repaid at closing | The single largest structural difference between the two |
| Speed to close | Weeks to months | Days to weeks | Senior lender consent is usually the long pole for C-PACE |
| Eligible use | Energy, water, resiliency work on the building | Almost any property purpose | C-PACE scope is set by state programme rules |
The difference that matters most
Everything in that table is secondary to one line: what happens when you sell. A bridge loan is a claim against you that has to be cleared out of the proceeds at closing. A C-PACE assessment runs with the property and passes to the buyer, along with the roof, the chiller and the envelope work it paid for.
This is why the objection people raise first — “I am not holding this for thirty years, so why would I take thirty-year money?” — has the logic backwards. The term is long because the improvements last that long, and you only carry the payments for as long as you own the building.
Where the bridge loan wins
Speed, and scope. If you need to close in three weeks, C-PACE will not get there — senior lender consent alone can take longer than that. And C-PACE only funds work that fits the state programme's eligible scope, which is narrower than “anything to do with the property.” Acquisition costs, tenant improvements outside the eligible categories, and working capital all sit outside it.
Running the numbers on your project
Our C-PACE calculator puts both structures on the same project amount so you can see the annual cost side by side, including what the bridge loan leaves owing at maturity. Then check whether your jurisdiction has a programme at all on the state coverage page.
What people ask when comparing these
Is C-PACE cheaper than a bridge loan?
Almost always on rate, and the gap widens over time because C-PACE amortises while a bridge loan usually does not. But the comparison is not clean, because they solve different problems. A bridge loan buys speed and flexibility on any property purpose; C-PACE buys duration and a fixed rate on a defined scope of building improvements.
Can I use C-PACE and a bridge loan on the same project?
Yes, and it is common. C-PACE sits in the capital stack as long-term fixed money for the qualifying improvements, and a bridge loan covers the acquisition or the non-qualifying scope. Both lenders will want to see the whole structure, and the senior lender consent conversation covers this.
Why would a lender consent to C-PACE sitting ahead of its mortgage?
Because the improvements it funds usually raise the value and the operating performance of the collateral, and because the assessment is a fixed, known amount rather than an open-ended claim. Senior lenders were sceptical of this for years and largely stopped being so around 2025, when C-PACE moved from niche to mainstream.
What if I plan to sell in three years?
That is an argument for C-PACE rather than against it. A bridge loan has to be repaid at closing out of your proceeds. A C-PACE assessment transfers to the buyer along with the improvements it paid for. Whether the buyer prices that as a liability or a benefit is a negotiation, but you are not writing a cheque to clear it.
