Rooftop solar shouldn't stall a mortgage refinance — but in Massachusetts it often does, because most lenders see a UCC-1 fixture filing or a third-party lease agreement before they see an appraisal. This guide walks through exactly how MA homeowners clear solar encumbrances during a refi: subordination agreements, PPA buyouts, lease acknowledgment letters, and how Fannie, Freddie, FHA, and VA each treat owned vs. leased panels.

What MA homeowners refinancing with solar need to know in 60 seconds
Rooftop solar does not block an MA refinance. It adds one document step: a subordination agreement (for secured solar loans) or a lease acknowledgment letter (for leases and PPAs). Most solar lenders sign these routinely.
Owned panels add appraised value. Leased panels do not. Fannie Mae and Freddie Mac both require appraisers to document the solar ownership structure. If you own the system, it counts toward the home's market value. If a TPO owns it, it's personal property and cannot contribute to the appraisal.
Section 25D is irrelevant to refinance. The residential solar tax credit expired December 31, 2025. It doesn't appear on any refinance paperwork. What matters is your UCC-1 status, your lease assumability clause, and whether your PPA has a buyout schedule you want to trigger. MA's SMART 3.0 production payments do show up indirectly — they document income-producing property for appraisal purposes.
How your system was financed determines the refinance paperwork. Start here.
You paid for the system in full. You own the panels, inverter, and racking outright. No lender or TPO has any claim.
Lien impact
No lien. No subordination needed.
Refi impact
Treated by underwriters like any real-property fixture. Typically adds measurable appraised value.
You financed the system through a solar-specific lender (Sunlight, GoodLeap, Mosaic, Dividend, EnerBank, Technology Credit Union, etc.). The loan is usually secured by a UCC-1 fixture filing recorded at the Registry of Deeds, NOT a second mortgage.
Lien impact
UCC-1 fixture filing at your county Registry of Deeds.
Refi impact
Your refinance lender will usually require the solar lender to sign a subordination agreement so the new mortgage sits in senior position. Expect a fee and a 2–4 week review cycle.
Some solar loans (Sungage, some credit unions) are unsecured personal loans with no property claim at all.
Lien impact
No recorded lien.
Refi impact
Treated like a personal loan for DTI purposes only. No subordination step. Your appraisal may still reflect the system as property.
A third-party owner (Sunrun, Sunnova, Tesla, SunPower, Trinity, etc.) owns the equipment on your roof. You pay a monthly lease in exchange for the electricity produced.
Lien impact
UCC-1 fixture filing on the EQUIPMENT ONLY (not the real property).
Refi impact
Lease must be assumable. Lender usually requires a lease acknowledgment letter and copies of the lease and any production guarantee. Most agencies do not count the lease payment against DTI if the system offsets the electric bill.
Same third-party ownership as a lease, but you pay per kWh generated instead of a fixed monthly fee. Price per kWh is usually below retail.
Lien impact
UCC-1 fixture filing on equipment.
Refi impact
Very similar to a lease for underwriting. PPA must be assumable and the buyer (refi borrower) needs to sign the acknowledgment. Some PPAs include a pre-payment or buyout option that can simplify the transaction.
The single document that trips up the most MA solar refinances.
A UCC-1 financing statement is a public record that declares a secured interest in personal property. Solar lenders and TPO companies file UCC-1s at the county Registry of Deeds to protect their claim on the equipment — specifically the panels, inverter, racking, and wiring. They are filed as fixture filings because the equipment is attached to real property but the lender's claim is only on the equipment, not the home itself.
In Massachusetts, UCC-1 filings are recorded at the Registry of Deeds for the county where the property sits. They're searchable by owner name at masslandrecords.com. Each UCC-1 stays active for five years and can be continued by a UCC-3 continuation filing. A release is filed as a UCC-3 termination when the underlying loan is paid off.
During refinance, the UCC-1 matters because your new mortgage lender wants to sit in first-lien position. A lien filed before the new mortgage would be senior unless the solar lender signs a subordination agreement that places the UCC-1 junior to the new mortgage. Without that document, the refi cannot close — title insurance will not issue.
Equipment lien
Covers panels, inverter, racking — not the home.
5-year term
Renewable via UCC-3 continuation. Released when loan paid.
Subordinate, don't remove
Refi needs subordination, not termination.
Run these seven steps in order. Most Massachusetts refinances with solar close in 40–60 days.
Find your original loan, lease, or PPA contract. Look specifically for the UCC-1 filing information, the subordination clause, the assumption clause, and any prepayment terms. Call the solar lender or TPO and ask for their refinance/subordination package by name.
Massachusetts Registry of Deeds records are searchable by county at masslandrecords.com. Look up your property by owner name and note every UCC-1 filing tied to the address. Your refinance lender will do this too — but surprises at closing delay you.
Once you have a new mortgage lender in underwriting, submit their subordination request to your solar lender. Typical fee is $250–$600. Turnaround is 10–30 days. GoodLeap, Sunlight, and Mosaic each have their own form. The document must match the new mortgage amount and recording county.
For leased or PPA systems, the TPO provider signs an estoppel/acknowledgment certifying that the agreement is assumable, that you are not in default, and that the equipment is not a fixture of the real property. Your refinance lender sends the form; the TPO returns it signed.
Tell the appraiser upfront that the system exists, who owns it, and the age. Provide the interconnection agreement, the SMART 3.0 statement, and any production records. Owned systems can be included in market value; leased and PPA systems typically cannot. Fannie Mae and Freddie Mac both require the solar-ownership structure to be documented in the appraisal.
PPAs and leases usually include a buyout schedule — often at year 5, year 7, and at the end of term. The buyout price is set by the contract, not the market. If your refi underwriter is balking at the lease, or you want to remove the UCC-1 entirely, a buyout during refinance can fold the cost into the new loan if your appraisal and LTV support it.
Eversource, National Grid, and Unitil all require a net metering agreement transfer when title changes — but refinance is not a title change. Keep your NM agreement on file at closing. If the refi involves removing a spouse from title, the utility needs a new customer-of-record on the interconnection.
Every agency treats owned vs. third-party-owned solar differently. Here is what MA appraisers are required to document.
| Loan Program | Appraisal Treatment |
|---|---|
Fannie Mae | Owned solar panels are considered real property and should be included in appraised value. Leased or PPA panels are personal property of the TPO and must not contribute to appraised value. UCC-1 for leased equipment is acceptable. |
Freddie Mac | Same general treatment as Fannie. Owned systems can be valued as a fixture; third-party-owned systems cannot. Appraiser must note the ownership structure in the report. |
FHA | Owned solar that is free of UCC-1 can be included in appraised value. Leased systems require the lease to be assumable and not pose a risk to title. HUD Handbook 4000.1 addresses solar specifically. |
VA | VA loans allow owned solar to contribute to value. Leases must be assumable and not a lien on the real property. Loan must still meet minimum property requirements. |
USDA Rural Housing | Rare in MA but present in some western/central counties. Follows general GSE treatment — ownership structure matters. |

At MA's electric rate of ~$0.28–$0.32/kWh, the math often works. Here are the variables.
At year 6 of a 20-year PPA on a 7 kW Sunrun system in Natick, the buyout price might land around $13,500–$17,000 depending on the contract. The system produces ~8,400 kWh/year. At an Eversource blended rate of $0.30/kWh, that's ~$2,520/year of offset value. Post-buyout, you stop paying the PPA ($0.14–$0.18/kWh) and keep the full offset plus any remaining SMART 3.0 payments. Whether the buyout pencils depends on your exact contract schedule, remaining SMART term, and how long you plan to own the home.
Example figures only. Request your actual buyout quote from the TPO provider — contracts vary.
Local bank, national lender, and credit union each handle solar differently in MA.
Local Massachusetts banks — East Boston Savings, Rockland Trust, Cambridge Savings, Eastern Bank, Salem Five — often keep loans on their own books and have internal policies for solar-equipped homes. Generally easier for unconventional ownership structures; some will work with unseasoned leases. Ask specifically about the solar UCC-1 policy before lock.
Most national lenders — Rocket, Guaranteed Rate, Movement, loanDepot — sell loans to Fannie or Freddie. They follow agency selling guide rules strictly: leased panels get lease-acknowledgment packages, owned panels with UCC-1 get subordination packages. Expect a more rigid process and less flexibility on unusual contracts.
MA credit unions — DCU, Workers, Metro, Hanscom, RTN — range from highly solar-friendly (DCU originates solar loans directly) to stricter than agency lenders. DCU's own solar loans require specific internal handling in a refi. Ask whether the credit union will subordinate its own solar loan during a mortgage refi — not all do.

MA homeowner refinance + solar, answered.
No, but it adds a subordination step. The UCC-1 is a fixture filing on the equipment, not a mortgage. Your new mortgage lender wants first-lien position, so the solar lender signs a subordination agreement that keeps the UCC-1 junior to the new mortgage. Fees are typically $250 to $600 and the turnaround is 10 to 30 days.
Yes. Most Massachusetts refinance lenders are familiar with leases from Sunrun, Sunnova, Tesla, and SunPower. The TPO provider signs a lease acknowledgment or estoppel letter certifying the agreement is assumable and that you are not in default. Fannie Mae, Freddie Mac, FHA, and VA all have written policies accepting leased solar as long as the lease is assumable and the equipment UCC-1 does not encumber real property.
Owned systems typically add measurable value in MA — published research suggests roughly a 3 to 4 percent lift in a high-rate state like Massachusetts, though individual appraisals vary widely by age of system, SMART 3.0 enrollment status, and comparable sales in the neighborhood. Leased and third-party-owned systems cannot legally contribute to appraised value per Fannie and Freddie policy.
No. The federal residential solar tax credit (Section 25D) expired December 31, 2025 and is not an active incentive for 2026 installations. It does not appear on mortgage paperwork. If your system was installed before the sunset and you already claimed the credit, it is irrelevant to the refinance. What does matter is SMART 3.0 enrollment (if applicable) because production payments can document income-producing property.
Not usually. Most solar lenders (GoodLeap, Sunlight, Mosaic, Dividend, EnerBank) routinely sign subordination agreements. The exceptions are some credit-union loans with strict seniority clauses. If the subordination is denied, you can either roll the solar loan payoff into the new mortgage (cash-out refi) or keep the existing loan and the refi in parallel.
Your loan or lease continues with the finance company, not the installer. Sunrun, GoodLeap, and Mosaic have servicing teams independent of the installer. Contact the finance company directly for the subordination or acknowledgment paperwork. If you cannot identify the loan servicer, pull the UCC-1 from your county Registry of Deeds — the filer is on the record.
Refinance does not transfer title, so your net metering agreement with Eversource, National Grid, or Unitil does not need to transfer. The only time NM transfer comes up is an actual sale. If the refinance changes the customer of record (for example, removing a spouse), the utility needs a new interconnection agreement signed by the new account holder.
Yes, and it can simplify underwriting. The PPA contract has a buyout schedule — typically available at years 5, 7, and at end of term. If your current appraisal and LTV support it, you can roll the PPA buyout into a cash-out refinance and eliminate the UCC-1 entirely. The math usually works if your electric rate is high (Massachusetts qualifies) and you plan to stay in the home more than five more years.
A typical MA refinance closes in 30 to 45 days. Add 10 to 21 days for solar subordination or lease acknowledgment in most cases. A PPA buyout rolled into the refinance can add another two weeks for the TPO to quote and process the buyout. Start the subordination request the same day you lock your rate.
