Banks That Offer an Investment Property HELOC With a Solar Lien or an Unpermitted ADU

The Quick Read: The lenders that write these lines depend on the instrument filed against the property and on the permit status of the unit. Few lenders write a line on a rental at all, and fewer will do it with a recorded solar lien or a unit the appraiser cannot count. Lendmire is a mortgage broker, so the useful question is which wholesale program fits the file, not which bank has a sign out front.

• On Lendmire’s network, an investment-property line caps at 70% CLTV and $500,000, with a 700 minimum credit profile.
• Not every solar item is a lien on the home. “Solar lien” can mean a recorded deed of trust, a fixture filing, a UCC-1, a PACE assessment or a lease or PPA, and these are five different problems.
• An unpermitted ADU is usually left out of value and rent, so the main house carries the file alone.
• The line must be titled to an individual or a revocable living trust. An LLC cannot hold title.
• A DSCR cash-out refinance is the usual fallback when the title or the collateral does not fit a line.

Why Do So Few Banks Write a HELOC on a Rental?

Big banks and large retail lenders mostly decline investment-property lines, or they offer a similar product under another name. The line is a second mortgage when a first mortgage exists, and the lender is taking a junior position behind a loan on non-owner-occupied collateral. That is a harder sell internally than a line on someone’s own home.

A HELOC is an open-end credit line you can draw on repeatedly, and the CFPB HELOC booklet describes sizing as a percentage of appraised value minus what is already owed. That math is simple. The hard part is the underwriting around it.

Across the wholesale network, the programs that do write investment lines share a profile. They underwrite the borrower personally, on credit and debt-to-income, not on the rent. They want the title in an individual’s name or a revocable trust. And they cap leverage tightly. That is why a broker who sees several programs is more useful than a single bank branch. The right program depends on property type, credit, how the property is titled, and what is recorded against it.

What Does an Investment-Property Line Look Like on This Network?

On an investment property, the ceiling is 70% CLTV. Both the 720-plus and 700-plus tiers reach that same 70%, so a higher score buys eligibility, not extra leverage. The minimum credit profile is 700, with no tier beneath it. The line runs from $25,000 up to a $500,000 maximum on an investment property.

Structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats and never converts to fixed. At least 75% of the line is drawn at closing. Debt-to-income tops out at 50%, and the lender reviews the file on the interest-only payment calculated on the maximum draw.

Because an investment line stops at $500,000, and full appraisals start only above that, these files normally run on an automated valuation. That matters for the ADU question below. Eligible property types include single-family, 2-4 units, PUDs, townhomes and condominiums. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural zoning are not eligible.

Availability is narrower than the DSCR footprint. These lines are offered in Lendmire’s 16 full-service states only. All figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend.

How Does Each Solar Instrument Show Up on Title?

“Solar lien” covers five different things, and lenders treat them differently. Classify yours before you ask anyone for a line.

PACE is the one federal agencies have addressed directly. The Federal Register notice on PACE records FHFA’s concern about super-priority liens and its direction that Fannie Mae and Freddie Mac not purchase or refinance mortgages carrying them. Those are agency rules and do not govern a wholesale HELOC. They do explain why lenders of every kind treat PACE as a priority-lien problem, since the assessment can rank ahead of a new lender.

A plain UCC-1 is the gray area. One lender reads it as a lien on equipment, not the home. Another wants it cleared. Ask before you pay for anything.

How Is a Solar Lien Cleared Before a Line?

Clearing depends on the instrument, and each type has its own paper trail.

1. Order a title report and a state UCC search. A county title search can miss a plain UCC-1. A fixture filing will appear.

2. Classify every solar item. Sort it as nothing, UCC-1 only, fixture filing, recorded deed of trust, or PACE.

3. Get a payoff or subordination letter. A lender may accept subordination on some items. Others require payoff.

4. Confirm the release. A UCC-1 or fixture filing is cleared by a filed and confirmed UCC-3. A recorded deed of trust needs a recorded release. PACE needs a payoff statement, full payoff and the administrator’s release. A UCC-3 does not clear PACE.

5. Order the appraisal or valuation only after that. This avoids paying for a valuation on a file that cannot move.

Paying off the solar loan does not remove the filing by itself. Someone has to file the termination, and someone has to confirm it posted. That is the step files skip.

A solar mortgage or PACE balance also reduces usable equity. A recorded solar deed of trust counts toward combined leverage, which at 70% CLTV leaves little room on a rental.

What Happens to an Unpermitted ADU?

The appraisal’s legal-use call governs, and an unpermitted unit is typically left out of both value and rent. Collected rent does not override that call.

The Urban Institute’s ADU financing paper notes that some ADUs counted in appraisal data may be unpermitted, and that rental income from a prospective ADU does not count in cash-out or home-equity products. Those products look at the property’s current value. The same paper reports, among California owners who built permitted ADUs and used mortgage products, that 56% used a HELOC or home equity loan, 35% used cash-out refinancing and 6% used renovation financing. Those figures describe permitted units, which is the point: permits are what let the unit count.

On a line that runs on an automated valuation, the unit may not be visible at all, but a borrower can request a full appraisal, and a lender can ask for a secondary valuation at higher leverage. Do not assume the unit stays hidden. Disclose it, and plan on the main house carrying the value.

Legalizing the unit can change this. It may require permits, inspections and a new appraisal before the unit counts. That work happens before the line, not after.

What If the Property Has Both Problems?

Fix the solar item first. It is usually the cheaper, faster-to-document problem, and it decides how much equity you have to work with. The ADU is a valuation question and a legalization project.

Think of the file in two layers. Layer one is title: what is recorded, what must be released. Layer two is collateral: what the appraisal will count. A line that clears layer one but sizes on a house with the ADU excluded may be smaller than the borrower expected.

A worked example in ratios, not dollars. Say an investor owns a rental whose first mortgage and a recorded solar deed of trust together already use most of the 70% CLTV cap. The room left for a new line is thin or gone. Pay off the solar item and that room reopens. Now suppose the appraisal also excludes the ADU. Value drops, and 70% of a lower number shrinks the line again. The order matters: classify, clear, then value.

Who Cannot Use This Product?

Anyone holding the rental in an LLC. Title must sit with the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a different product.

Other limits apply too. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible. Credit must be 700 or better on an investment property, and the report cannot be more than 90 days old at closing. Bankruptcy needs 4 years of seasoning. Foreclosure history follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure or short sale follows 4 years.

When Does a DSCR Cash-Out Fit Better?

A DSCR cash-out fits when title, leverage or collateral rule out a line. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, not on the borrower’s personal income and DTI. It can be held in an LLC, subject to lender program eligibility. For background, see the complete DSCR loans guide.

The tradeoff is real. A cash-out refinance replaces the first mortgage instead of sitting behind it, so the borrower gives up the existing loan. On the network, cash-out tops out around 75% LTV on a standard rental, with about 6 months of seasoning the common expectation. Select lenders in the network also offer coverage below 1.00 with leverage and terms adjusted. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Remember what DSCR measures: rent against the full monthly obligation. Clearing the ratio does not mean positive cash flow, since repairs, vacancy, management and utilities sit outside it. Unpermitted ADU rent is typically excluded, so the main house must carry the ratio alone, and PACE or recorded solar debt typically has to be resolved first.

Key Terms Defined

UCC-1: a public notice filed to claim an interest in equipment, such as solar panels.

UCC-3: the filing that terminates or amends a UCC-1; it must be filed and confirmed.

Fixture filing: a UCC filing recorded in county land records, so it appears in a title search.

PACE: an assessment repaid on the property tax bill that carries tax-lien priority.

CLTV: combined loan-to-value, meaning all liens added together and divided by value.

DSCR: the ratio of a property’s rent to its monthly obligation (principal, interest, taxes, insurance and any HOA dues).

What Should You Gather Before Calling Anyone?

• The solar contract, plus the loan, lease or PPA paperwork
• The UCC-1 itself, and a payoff or subordination letter
• A current title commitment showing how the property is vested
• Permits and final inspection for any ADU
• Your first mortgage statement and a credit profile at 700 or better
