The Quick Read: No single provider is the right answer, because which lenders will write these files depends on how the solar item is recorded, what the appraisal does with the ADU, and the occupancy of the property. Lendmire is a mortgage broker, not a lender, and does not rank providers. It shops a network of wholesale HELOC lenders and matches the file to the program.
- A solar lien is several different instruments under one label. A lease or equipment-only filing is treated very differently from a recorded deed of trust or a property-tax assessment.
- An unpermitted ADU is usually left out of living area and often out of value, so it shrinks your equity base instead of adding to it.
- On an investment property, this network’s home equity lines top out at 70% combined loan-to-value (CLTV) with a 700 minimum credit score.
- Clearing a solar item before you apply, or legalizing the unit first, often changes which lenders will look at the file.
- Every outcome is subject to lender guidelines, full file review, and underwriting. Nothing here is a commitment to lend.
Why Providers Can’t Be Ranked
A ranking would mislead you. Each lender in a wholesale network sets its own overlays for solar filings, permit status, and combined leverage. A lender that shrugs at a precautionary equipment filing may refuse a file with a recorded solar mortgage. Another may take the solar item but decline any property with an unpermitted second unit.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
That is why a broker’s job here is matching, not listing. The best program for your situation depends on the instrument on title, the appraisal result, your credit profile, and how much combined leverage you need.
This article walks through how underwriting treats each problem, the structures that exist, where the general rule breaks, and what the decision looks like in practice.
What Is a HELOC, and How Is It Different From a DSCR Loan?
A HELOC is a home equity line of credit. It is a revolving line secured by a lien on your property, and it sits in first or second position depending on what is already recorded. On this network it is a standalone line, not a feature bolted onto your mortgage.
A DSCR loan works differently. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide covers that product end to end.
A HELOC leans on your personal profile. It uses a debt-to-income (DTI) ratio capped at 50%, calculated on the interest-only payment at the maximum draw. Credit and equity matter most.
The title structure also differs. HELOC collateral must be titled in your own name or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your rental already sits in an LLC, you need either a vesting change or a DSCR cash-out refinance, which is available subject to lender program eligibility.
The Program Parameters That Frame Everything
Occupancy changes the numbers a lot, so the ceiling for your line depends on what the property is. The figures below are typical ranges from select wholesale lenders, and each is subject to lender guidelines.
| Occupancy | Max CLTV | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% | 700+ | $500,000 |
| Second home | 90% | 720+ | $500,000 |
| Primary residence | 90% | 720+ | $500,000 |
The 90% figure on second homes and primary residences exists only at a 720-or-better profile. Lower scores step the ceiling down. On an investment property there is no tier above 70%. If a market survey tells you equity lines reach higher, that describes the broader market and not this network.
Other features matter for these two problems:
- Draw structure: Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Primary and second-home lines can also use a 3-year draw with a 17-year repayment.
- Draw at closing: At least 75% of the line is drawn at closing. The line behaves like a mostly funded loan, which matters if you plan to retire a solar balance from proceeds.
- Valuation: Lines at or below $500,000 ordinarily use automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you can always ask for a full appraisal. Every line above $500,000 gets a full appraisal.
- Availability: These HELOC programs are offered in 16 full-service states, a narrower footprint than Lendmire’s DSCR platform of 40 states plus Washington, D.C.
- Ineligible properties: Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.
How Underwriting Treats a Solar Lien, Step by Step
Underwriting starts by asking what is recorded, because a HELOC takes its position from the public record and not from the product name. That means the first question is which solar arrangement you have.
Step 1: Classify the solar arrangement
Lenders sort solar into owned outright, leased or power purchase agreement (PPA), financed with a filing, financed with a recorded deed of trust, or PACE. The evidence is your financing agreement, a county recorder search, and a separate line on your tax bill.
| Instrument | Where it shows | Typical effect |
|---|---|---|
| UCC-1 on equipment | State filing office | Often tolerated |
| UCC fixture filing | County land records | Priority problem |
| Solar deed of trust | County land records | Counts in CLTV |
| PACE assessment | Property tax bill | Hardest case |
Step 2: Run title
A fixture filing and a recorded solar mortgage both surface in a title search or commitment. A plain state-level UCC-1 may need its own search, so a county title commitment can miss it.
Step 3: Choose a clearance path
There are three: payoff, release, or subordination. Payoff means the solar creditor issues a payoff statement and gets paid at closing. The creditor then files a UCC-3, which is the termination form.
Paying the balance does not remove a filing until that UCC-3 is on record. Subordination moves the solar creditor behind the new lien without removing it. It needs the solar company’s agreement and the new lender’s acceptance, and nothing forces either party to agree.
Step 4: Count combined leverage
Any recorded solar lien or assessment joins your first mortgage in the CLTV total. On an investment line capped at 70% CLTV, that balance eats usable equity directly. This is where files with thin equity stop working on paper.
Step 5: Document it
Gather the title report, the solar contract or lease, the UCC-1 itself, any payoff or subordination letters, and your tax bill. If PACE is involved, add the PACE payoff statement.
Where the Solar Rule Breaks: Named Edge Cases
Lease or PPA. The provider usually files a UCC against its own equipment, so the panels are not your collateral. In the agency channel, Fannie Mae’s guidance on special property considerations says panel value must not be counted when a lease or PPA controls, even with a precautionary filing. That is a contrast point only, since agency rules do not govern these wholesale HELOC programs.
Fixture filing versus plain UCC-1. A fixture filing, if properly made, can have priority over a later-recorded mortgage. An equipment-only filing with the state is generally the milder problem.
The “is it a lien on my house” argument. Solar providers describe their UCC as notice of equipment ownership. Title companies often still want it handled. Treat the answer as lender-specific and file-specific.
PACE. This is the outlier. Fannie Mae’s PACE loan guidance says these loans typically carry first-lien priority over earlier-recorded mortgages. It also says the borrower needs enough equity to pay off the PACE obligation as a condition of a new mortgage. A law-firm publication on PACE securitizations adds that the assessment is repaid through the property tax bill and travels with the property, not the borrower.
A UCC-3 does nothing for PACE. Only a payoff clears it. For most wholesale lenders, a PACE balance is the solar item most likely to end the conversation unless you retire it first.
An open zero-balance line. An earlier HELOC stays a recorded lien until it is formally closed. Subordination is not automatic, so confirm any old line is closed on the record.
How Underwriting Treats an Unpermitted ADU
The appraisal decides the ADU’s fate, not your rent roll. The appraiser determines whether the unit is legal, legal non-conforming, or unpermitted, and whether it counts in gross living area. The lender follows that appraisal.
NerdWallet quotes the Appraisal Institute’s president saying that unpermitted construction could make a home tough to sell or refinance and could invite zoning enforcement. AAA AMC, an appraisal management company, says unpermitted space may be excluded from gross living area and can lead to delays or denial. Gather ADU reports that most lenders assign no value to unpermitted structures and that appraisers must note them.
Outcomes still depend on the appraiser and the lender. Missing permits do not always erase value entirely, but you should plan on the unit being excluded.
| Scenario | Valuation effect | Typical fix |
|---|---|---|
| Permitted, legal unit | Counted in value | None needed |
| Legal non-conforming | Depends on appraiser | Document history |
| Unpermitted unit | Often excluded | Legalize first |
| Unpermitted, rented | Rent still not counted | Legalize first |
Collected rent from an unpermitted unit does not override the appraiser’s legal-use analysis. A tenant paying you does not make the space count.
The automated valuation that ordinarily applies to lines at or below $500,000 does not make the unit invisible. A lender can still require a secondary valuation or a full appraisal. The unit still affects resale and future refinancing, and a late-surfacing title or appraisal issue can force a renegotiation.
What Happens When You Have Both Problems
When both issues sit on one property, they hit from two directions. The solar item reduces usable equity, and the ADU adds no appraised value. The result is a smaller value base carrying a bigger lien stack.
A common sequence works like this:
1. Get the facts. Pull the permit history, order a title search, and read your solar agreement.
2. Fix the instrument that blocks the most lenders. For PACE, that means a payoff. For a fixture filing, that means a release or subordination.
3. Decide on the ADU. Either legalize it, which involves permits, inspection, and a new appraisal, or accept that it carries no value and size the line without it.
4. Recalculate CLTV. Use the appraised value without the ADU and with the remaining liens.
5. Then shop the file. Bring the updated numbers to the lender match once the earlier steps are settled.
Paying off solar before you apply shrinks the combined-lien count, but the cash has to come from somewhere. Some appraisals can be made subject to legalization, which means the work happens before the loan funds. Ask the lender whether it will accept that structure.
Owner-Occupied Versus Rental: What Changes
Occupancy changes the ceiling, the credit floor, and the line size. A primary residence can reach 90% CLTV at 720 or better, up to $500,000. An investment property is capped at 70% CLTV with a 700 minimum.
That gap makes the solar balance and the ADU more costly on a rental. The same lien stack that fits under a primary-residence ceiling can push an investment file over 70%. Lendmire’s walkthrough of how an investment property HELOC works with a solar lien or an unpermitted ADU goes through that math.
Alternatives to a HELOC
Sometimes the line is the wrong tool. A few cases push investors elsewhere:
- The property sits in an LLC. A HELOC cannot be written there. A DSCR cash-out refinance, subject to program terms, may fit better.
- PACE is the problem. Paying it off through a refinance can be cleaner than layering a second lien over it.
- The ADU is the equity issue. Legalizing it first can restore value, though any lift depends on comps and underwriter review.
DSCR loans have their own limits. Most programs in the network start coverage at 1.00, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, and management sit outside the calculation.
Key Terms Defined
UCC-1: The filing that gives a creditor public notice of its claim on personal property, such as solar panels.
UCC-3: The termination form a creditor files to remove a UCC-1 after payoff.
Fixture filing: A UCC-1 recorded in county land records, which can rank ahead of a later mortgage.
PACE: A clean-energy assessment repaid through the property tax bill that typically outranks the mortgage.
CLTV: Combined loan-to-value, meaning all liens on the property divided by its appraised value.
Subordination: An agreement that moves an existing lien behind a new one, which the existing lender must approve.
Pre-Application Checklist
- Title report or commitment
- Solar contract, loan, or lease, plus the UCC-1
- Payoff or subordination letters
- PACE payoff statement and the tax bill, if applicable
- Permit history for the ADU
- Proof of vesting in your name or a revocable trust
- Recent credit report, since lenders pull a single-bureau score; how recent it needs to be varies by file and lender
Frequently Asked Questions
Can I get a HELOC if I have a solar loan, lease, or PPA?
Often, yes, but it depends on the instrument. A lease or PPA usually puts only an equipment filing on record, which many lenders tolerate. A recorded solar deed of trust counts in combined leverage, and PACE is the hardest case. Treatment varies by lender and file.
Do I have to pay off the solar loan first?
Not always. Payoff is one of three paths, alongside release and subordination. Subordination needs the solar company’s cooperation, and nothing forces it. Payoff is the cleanest route when PACE is involved, because only a payoff clears that assessment.
Does an unpermitted ADU count toward my home’s value?
Usually not. Practitioners report that unpermitted space is typically excluded from living area and often from value. The outcome depends on the appraiser and the lender. Plan the line without the unit’s value unless you legalize it first.
Which type of lender will lend behind these problems?
That varies by lender, which is why a broker shops several. Some will take an equipment-only filing but not a recorded solar mortgage. Others decline unpermitted units outright. Lendmire cannot name a provider that will approve your file, because every file is underwritten individually.
What if I own the rental through an LLC?
These HELOC programs cannot hold title in an LLC, so you would need a vesting change or a different product. A DSCR cash-out refinance is the usual alternative, subject to lender program eligibility.
