Loan Officer's Guide to C-PACE Financing

Your client — an investor who’s graduated into commercial real estate — is developing a mixed-use building and tells you he’s short in the capital stack. The senior loan covers most of it, but he’s facing a big gap he’d have to fill with expensive equity, and a chunk of his budget is going toward a new HVAC system, LED lighting, solar, and a resilient roof. He’s frustrated that all that “green” spending isn’t unlocking any special financing. And you, thinking in conventional mortgages, have never heard of the tool that’s built for exactly this.

That tool is C-PACE — and it’s one of the most useful, least-understood financing structures in commercial real estate. This guide explains what C-PACE is, how its unusual repayment works, how it stacks with a senior mortgage, and how — through a referral relationship — you get paid on a sophisticated deal most loan officers don’t even know exists. It links to current terms on our C-PACE financing page.

What C-PACE actually is

C-PACE stands for Commercial Property Assessed Clean Energy. It’s long-term financing for energy, water, and resiliency improvements on commercial property — and the thing that makes it unlike anything on your rate sheet is how it’s repaid.

Instead of a conventional loan payment, C-PACE is repaid through a voluntary special assessment added to the property’s tax bill, paid over a very long term (often 20–30 years). Because the obligation is structured as an assessment on the property rather than a personal loan, it behaves in a fundamentally different way:

• It attaches to the property, not the borrower. On a sale, the assessment typically transfers to the new owner.
• It offers very long terms. 20–30 years is common — far longer than most commercial debt.
• It’s competitively priced. The assessment structure and security support attractive rates.
• It funds specific improvements. Energy efficiency, renewables, water, HVAC, resiliency — on new builds and retrofits alike.
• It’s enabled state by state. C-PACE exists where state and local programs authorize it, so availability varies by market.

The mental model: C-PACE turns eligible “green” building spend into a long-term, property-secured slice of the capital stack — money a developer would otherwise have to cover with pricier equity.

What it pays for — and why owners want it

C-PACE funds a defined menu of improvements on commercial property:

• Energy efficiency — HVAC, lighting, insulation, building envelope, controls.
• Renewable energy — solar and other on-site generation.
• Water conservation — fixtures, systems, and efficiency upgrades.
• Resiliency — seismic, wind, flood, and other hardening measures.

It works on both new construction and existing buildings, which is why it shows up in two very different situations: a ground-up commercial development funding eligible improvements as part of the build, and an existing-building retrofit where an owner upgrades systems and finances it over decades. In both, the appeal is the same — long-term, competitively priced capital for spending the owner was going to do anyway.

If your client’s commercial or construction deal has an energy or resiliency component, C-PACE may fit. Send us the scenario and we’ll help you see whether it does.

How C-PACE stacks with the senior loan

This is the concept that makes you sound like you understand the capital stack. C-PACE doesn’t replace the primary commercial mortgage — it sits alongside it as a separate assessment. On a development, the stack might look like: senior loan + C-PACE + equity. The C-PACE piece fills a gap that would otherwise require more equity or expensive mezzanine debt, which improves the developer’s returns.

The catch — and the reason this is a coordinated, specialist transaction — is priority. Because the C-PACE assessment carries a tax-like priority position, it typically requires the senior lender’s consent. Structured properly, everyone wins: the senior lender keeps its position, the owner reduces required equity, and the improvements get funded over a long term. That coordination is exactly why these deals belong with a partner who arranges them, not a generalist.

The deals that are really C-PACE files

You’ll recognize the opening when a commercial-minded client describes one of these:

The borrower…	C-PACE answer
Is developing commercial property with energy/resiliency spend	C-PACE fills part of the new-construction stack
Owns a building and wants to finance an energy retrofit	C-PACE on existing-building improvements
Is short equity on a commercial project with eligible improvements	C-PACE reduces the equity gap
Is adding solar, HVAC, or resiliency upgrades to a commercial asset	Long-term assessment financing
Wants long-term, off-balance-sheet-style financing for green spend	C-PACE’s 20–30 year assessment structure

If it’s a commercial deal with an energy, water, or resiliency component and a capital gap, there may be a C-PACE referral inside it — one almost no residential LO would ever spot.

Terms and factors to set expectations

You won’t quote these, but framing them makes you the advisor who knew the tool existed:

• Term: long — often 20–30 years, matched to the useful life of the improvements.
• Rate: competitive, supported by the assessment’s security.
• Repayment: via the property tax bill, as a special assessment.
• Eligibility: the improvements must qualify under the applicable state/local program, and the property must be in a jurisdiction that offers C-PACE.
• Senior consent: typically required, so coordination with the primary lender is part of the process.

The framing that resonates with a commercial client: C-PACE is long-term, competitively priced capital for building improvements that reduces the equity you’d otherwise tie up — and it stays with the property when you sell.

A worked example you can walk a borrower through

Your client is developing a $10,000,000 commercial project, with ~$1,500,000 of eligible energy and resiliency improvements. The senior loan tops out at $6,500,000, leaving a $3,500,000 gap he’d fill with equity.

• C-PACE for eligible improvements: ~$1,500,000 over a 25-year assessment
• Result: the equity gap shrinks from $3,500,000 to ~$2,000,000
• Structure: senior loan ($6.5M) + C-PACE ($1.5M) + equity ($2M), with senior-lender consent
• Why it works: the owner finances green spend he was doing anyway over 25 years, freeing up equity for returns
• What you did: recognized that a chunk of the budget was C-PACE-eligible and routed a tool most lenders never mention

When you can sketch that stack, you’re not a residential LO out of your depth — you’re the person who brought a sophisticated commercial client a structure he didn’t know he could use.

How the C-PACE file moves, step by step

Stage	What happens
1	Borrower submits the project, the eligible improvements, and the jurisdiction
2	Program eligibility confirmed (improvements + location) and the C-PACE amount sized
3	Senior lender consent obtained and the capital stack coordinated
4	Assessment documented with the local program
5	Funding closes; repayment begins via the property tax assessment

The critical-path items are program eligibility and senior-lender consent. Coach the borrower to confirm the property is in a C-PACE jurisdiction and to loop in the senior lender early.

What your borrower will ask you — and how to answer

“I pay this through my property taxes?” Yes — it’s a special assessment on the tax bill, paid over a long term. That structure is what lets it stay with the property and offer 20–30 year terms.

“Does it replace my regular commercial loan?” No — it sits alongside it, filling part of the stack so you need less equity. Your senior lender consents to the arrangement.

“What can I actually finance with it?” Energy efficiency, renewables, water, HVAC, and resiliency improvements — on new construction or an existing building.

“What happens when I sell?” The assessment typically transfers with the property to the new owner, since it’s attached to the real estate rather than to you personally.

“Is it available everywhere?” No — it depends on state and local programs, so availability varies by market. That’s the first thing to confirm.

A second example: the existing-building retrofit

Your client owns an older commercial building and wants to finance a $600,000 energy retrofit — new HVAC, LED lighting, and a solar array.

• C-PACE for the retrofit: ~$600,000 over a long-term assessment
• Why it works: the upgrades qualify, the building is in a C-PACE jurisdiction, and the owner finances it over decades instead of out of pocket
• What you did: turned a “how do I pay for these upgrades?” question into a referable, differentiated financing solution

The lesson: C-PACE isn’t only for big new developments. An existing-building retrofit is one of the most common uses — and recognizing it is a differentiator almost no residential LO offers.

C-PACE vs. commercial vs. construction: a cheat sheet

	C-PACE	Commercial	Construction
Repaid via	Property tax assessment	Loan payment	Loan payment / takeout
Funds	Energy / water / resiliency improvements	Income property purchase/refi	Ground-up build
Term	20–30 years	5–10 yr term / 25–30 am	12–24 months
Stays with	The property	The borrower	The borrower
Role in the deal	Fills the stack, cuts equity	Senior debt	Short-term build debt

The pattern: C-PACE is a specialized slice of the commercial capital stack — long-term, property-secured financing for green and resilient improvements that reduces the equity a project needs. It complements the senior loan rather than replacing it.

Your move: refer it

C-PACE is a coordinated, specialist transaction, so the right path is to refer it:

Refer it. Send the project and the eligible improvements; Jaken Finance Group evaluates program fit and coordinates the C-PACE piece with the senior lender; you’re paid a referral fee. The right path for essentially every residential LO here.

The compliance note specific to you: your consumer-mortgage referral-fee limits come from RESPA, which governs consumer-purpose residential transactions. C-PACE is a commercial, business-purpose financing tool — a different category, which changes the analysis. Program rules and state licensing vary, so confirm your specifics with compliance or counsel before accepting a fee.

The clean start is our referral-partner program: flag the deal, we handle program eligibility, senior-lender coordination, and disclosures, and you keep the relationship with a sophisticated commercial client. If a broker relationship fits your situation, reach out here.

The bottom line

C-PACE isn’t a product you’ll underwrite from a residential desk — it’s a sophisticated capital-stack tool most loan officers don’t even know exists. The developer short on equity, the owner financing an energy retrofit, the commercial project with a resilient roof and a solar array: every one may have a C-PACE referral inside it. You don’t need to master assessment law or program eligibility. You need to recognize a commercial deal with an energy or resiliency component and a capital gap — and have a partner who arranges it.

Your client is going to build or retrofit that building this year. The only question is whether you’re the one who showed him the financing tool that made the numbers work. Send us the scenario and we’ll tell you whether C-PACE fits.
