What is PACE Financing and When Is It the Right Choice
PACE (Property Assessed Clean Energy) is a financing mechanism for solar and energy improvements repaid through your property tax bill. SundayBuild recommends avoiding PACE — its senior lien position blocks Fannie/Freddie/FHA/VA refinancing, rates run 5-9%, and the door-to-door sales channel is aggressively misaligned with borrower interests.
PACE (Property Assessed Clean Energy) is a financing mechanism for solar, battery, HVAC, and energy-efficiency improvements that is repaid through a special assessment on your property tax bill rather than a conventional loan. It sounds convenient — a contractor at your door offers 'no-credit-check financing with payments on your taxes' — and that convenience is exactly the problem. SundayBuild recommends avoiding PACE in almost every situation, for three structural reasons that do not change with market conditions: (1) PACE liens are SENIOR to your first mortgage, which means Fannie Mae, Freddie Mac, FHA, and VA all require PACE payoff before they will refinance your mortgage or issue a new first lien. Taking PACE blocks your ability to refinance until you pay it off. (2) PACE rates are typically 5%-9% APR with significant origination and administrative fees — higher than nearly every alternative (HELOC, solar-specific loan, personal loan, or including the cost in a new construction loan). (3) PACE is aggressively sold by door-to-door contractors and home improvement sales reps who receive referral compensation — the incentive alignment favors the seller, not the homeowner. The only situations where PACE is genuinely the right answer are narrow: (a) you have no other financing option (poor credit, no equity, no cash) AND you urgently need the improvement (e.g., a failing HVAC system in summer), AND (b) you do not plan to sell or refinance your home during the repayment period. For California solar specifically, the better answers in priority order are: cash, HELOC (see Q48), manufacturer solar loan, or folding solar costs into a construction loan on new builds (see Q45).
Key Facts
- PACE liens are SENIOR to your first mortgage. This is the defining structural problem — most other financing types sit BEHIND the mortgage, but PACE sits AHEAD of it.
- Fannie Mae, Freddie Mac, FHA, and VA all require PACE payoff before they will refinance your mortgage or underwrite a new first lien. Taking PACE effectively locks you out of refinancing until the PACE balance is cleared.
- PACE rates are typically 5%-9% APR, higher than HELOC (which usually prices at Prime + 0%-2%), solar-specific loans, personal loans for prime borrowers, and construction loans.
- PACE is repaid through a property tax special assessment — the payment is added to your annual tax bill, not as a separate loan payment. Missing it can trigger tax-lien consequences.
- PACE is aggressively sold by door-to-door contractors and home improvement sales reps who receive referral compensation from PACE administrators. The sales channel incentive is not aligned with borrower interests.
Decision Rules
If: You have any other financing option available (HELOC, solar loan, personal loan, cash, construction loan)
Then: Use that option. PACE's rate, sales channel, and refinance-blocking problems make it worse than every standard alternative.
If: You plan to sell or refinance your home within the PACE repayment period (10-25 years)
Then: Avoid PACE. You will have to pay it off (or the buyer will demand a price reduction) at the time of sale or refinance.
If: You have poor credit, no equity, and an urgent energy improvement need (failing HVAC, critical solar install)
Then: PACE may be a last resort. Verify you understand the refinance-blocking implications and do not plan to move. Consider whether delay or a government assistance program is viable first.
If: You're building new construction and want solar
Then: Fold the solar cost into your construction loan rather than using PACE. The construction loan rate is lower, and it avoids all PACE structural problems. See Q45.
California-Specific
- California was the original PACE market — HERO (Renovate America), Ygrene, and CaliforniaFIRST are the three dominant California programs.
- California law requires PACE administrators to comply with ability-to-repay rules and enhanced consumer protections under AB 1284 (2017) and subsequent updates. Nonetheless, enforcement against aggressive sales tactics has been inconsistent.
- California homeowners with PACE liens frequently discover the refinance-blocking problem only when they try to refinance a year or two later — long after the contractor has moved on.
- For California solar specifically, a HELOC is almost always a better answer than PACE. California credit union HELOCs at Prime + 0%-2% beat PACE at 5%-9% by hundreds of basis points.
Common Misconceptions
PACE is a government program so it must be safe.
PACE is a government-enabled private financing mechanism. The local government authorizes the assessment but private PACE administrators (Renovate America, Ygrene, CaliforniaFIRST) set the terms and collect the interest. Government authorization doesn't make it a good financial product.
PACE payments are tax-deductible because they're on the tax bill.
The interest portion of PACE payments is NOT deductible as property tax. Only the base property tax portion is deductible. The PACE assessment is more analogous to a loan payment than a tax.
PACE has no impact on my mortgage.
PACE is a senior lien that takes priority over your mortgage. It directly blocks your ability to refinance with Fannie Mae, Freddie Mac, FHA, or VA — the four largest mortgage programs in the U.S.
Limitations & Gaps
- Specific current PACE program rates are not tracked in this topic. Rates vary by program, improvement type, and loan term.
- Some niche situations (very-low-credit borrowers with urgent weatherization needs) may still make PACE the least-bad option. This topic does not deep-dive those edge cases.
