Can You Get an Investment Property HELOC With a Solar Lien or an Unpermitted ADU?

The Quick Read: It depends on which instrument sits on title: an unpermitted ADU usually does not block an investment property HELOC because the line can be sized with the unit valued at zero, while a recorded solar mortgage or a PACE assessment has to be paid off or counted against your equity, and an equipment filing is handled lender by lender. Think of it as two separate problems. The solar item is a title problem, and the ADU is a valuation problem.

• A solar lien is not one thing. An equipment filing, a county fixture filing, a recorded solar mortgage, and a PACE assessment each behave differently.
• PACE is the hardest to work around, because it is a tax assessment that gets paid ahead of mortgages.
• An unpermitted ADU rarely gets value credit or rent credit, so size the line as if the unit were not there.
• Across Lendmire’s wholesale network, an investment property line caps at 70% CLTV and $500,000, with a 700 minimum credit score, subject to lender guidelines.
• If the equity only works with the ADU counted, the file probably does not work.

Why Solar and ADUs Create Different Problems

A solar lien affects who gets paid first. An unpermitted ADU affects what the property is worth. Investors often lump the two together because both show up as “weird stuff on a rental,” but they get fixed in different ways and on different timelines.

The lien problem lives in the title report. Lenders want a clear picture of every claim against the property. The valuation problem lives in the appraisal or automated value. The question there is whether the unit counts toward the property’s worth at all.

Why does that split matter? A solar issue can often be cleared with paperwork and a payoff. An ADU issue usually cannot be paperworked away. It takes a permit process, or it takes a plan that never leans on the unit.

Key Terms Defined

CLTV: Combined loan-to-value, meaning every lien on the property added together and divided by its value.

UCC-1: A state-level filing that gives a solar lender a claim on the equipment, such as the panels, rather than on the land itself.

UCC-3: The termination filing that removes a UCC-1 from the record, which the secured party files after payoff.

Fixture filing: A UCC-1 recorded in the county land records, so it shows up in a title search and is treated much like a lien on the property.

PACE: A property tax assessment used to finance energy improvements, repaid through the tax bill.

Subordination: A recorded agreement in which one lender agrees to rank behind another.

What Kind of Solar Item Is on Your Title?

Five arrangements cover nearly every rental with solar. Each one leaves a different footprint, and that footprint decides whether the HELOC is easy, awkward, or off the table.

The federal consumer-finance regulator’s Issue Spotlight on solar financing notes that solar lenders commonly file UCC liens on the panels themselves. That lien is technically not on the property, but it can muddy title because some jurisdictions treat it as reaching the whole property. That is why title companies often ask for a termination or a recorded subordination even when the balance is small.

Across the programs Lendmire places files with, the equipment-only filing is the gray zone. Some lenders accept it with a release letter. Others want it gone. A recorded solar mortgage or a fixture filing is stricter, since it reaches the real estate. Lenders treat it as a lien that counts.

The PACE Exception

PACE gets its own paragraph because it behaves differently. The CFPB describes these loans as secured by a property tax lien and repaid through property taxes. In its proposal announcement, the agency notes that PACE loans get paid ahead of first mortgages at a foreclosure sale.

That priority is the reason a new lender will not take a position behind it. The rule itself addresses ability to repay at origination. It does not change where PACE ranks. In practice, a PACE balance has to be paid off before a new line goes on.

How to Find Out What Is Actually Recorded

Start with facts, not guesses. Many investors inherit a solar system from a prior owner and have never seen the paperwork.

1. Pull the title report or commitment and classify every solar item.

2. Check the county records for fixture filings and the state UCC index for equipment filings.

3. Look at the tax bill for a PACE line.

4. Ask the solar provider whether the system is owned, financed, or leased.

5. Pull permit history for every structure on the lot, including the ADU.

A lease or PPA often leaves only a provider filing. There may be no balance to count. Whether the lease payment counts as debt varies by lender.

Clearing a Solar Filing: Payoff, Transfer, or Subordination

There are three clearing paths, and they are not interchangeable.

The first is payoff plus a UCC-3 termination. Paying the loan does not clear the filing by itself. The secured party has to file the termination, and the title company will want to see it recorded or confirmed. Many investors pay off the balance and assume the record cleans itself. It does not.

The second is a lease or PPA transfer, which needs the provider’s consent. The third is a signed subordination. Here is the catch: a signed letter is not the same as a recorded one. Title companies want a recorded termination or a recorded subordination. The request goes to the solar lender, not the new lender, and it is never guaranteed.

What the Network Actually Offers on Investment Lines

An investment property HELOC placed through Lendmire’s wholesale network is a standalone line in first or second lien position. Across the select lenders involved, the main figures look like this, always subject to lender guidelines and full file review:

• Leverage: 70% CLTV on an investment property, with no higher tier.
• Credit: 700 minimum. Both the 700 and 720 tiers reach the same 70% CLTV, so a higher score buys eligibility, not leverage.
• Line size: up to $500,000 on an investment property.
• Structure: a 5-year draw followed by a 25-year fully amortizing repayment, with at least 75% of the line drawn at closing.
• DTI: 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
• Property types: single-family, 2-4 units, PUDs, townhomes, and condos. Manufactured homes and log homes are not offered.

Market surveys report that investment property HELOCs commonly ask for a 720 credit score and are stricter than lines on a primary home. The network figure for an investment line is a 700 floor and 70% CLTV.

The line is reviewed on the borrower’s personal credit, DTI, and CLTV, not on the property’s rent. Availability is limited to Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint.

Worked Example: The Same Property Two Ways

Run the numbers on a modeled rental. These are assumptions, not market data. Say the automated value is 100 units, and 8 of those units come from credit for an unpermitted ADU. The first mortgage is 50 units, a recorded solar mortgage is 6, and the new line would be 12.

• ADU counted: 68 units of liens against 100 of value is 68% CLTV, just under the 70% ceiling.
• ADU at zero: value falls to 92 units, and the same 68 units of liens equals roughly 74% CLTV.

At 70% of 92 units, the room for liens is about 64 units. The first mortgage and solar balance already use 56, so the line shrinks to roughly 8 units, not 12. The deal moved because of the ADU credit, not because of the solar.

Now clear the solar mortgage first. With the 6-unit solar balance gone and the ADU at zero, liens are 62 units against 92 units of value, roughly 67% CLTV. That sits under the 70% cap, so the full 12-unit request would fit. Solar payoff and ADU valuation both change the same number, so fix them in one order.

The Right Order When You Have Both

Sequencing keeps the borrowing number from moving twice.

1. Classify the solar item from the title report.

2. Decide whether to pay it off, transfer it, or seek a subordination.

3. Confirm the termination or subordination is recorded.

4. Size the line with the ADU at zero.

5. Decide separately whether legalizing the ADU is worth doing before a later refinance.

6. Disclose the unpermitted unit accurately. Hiding it creates risk that outlives the loan.

Title Vesting: The LLC Problem

This is where many investors get stuck. On this network’s HELOC, the property has to be titled in the individual borrower’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change before a line is possible. Otherwise the better route is a DSCR cash-out.

When the HELOC Is the Wrong Tool

A HELOC fits when you want a revolving line and have the personal credit and DTI to carry it. A DSCR cash-out refinance fits when the rent should drive qualification. As Lendmire’s complete DSCR loans guide explains, qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.

Most DSCR cash-out files in this network want about six months of seasoning and a first-lien position that is clean. A solar filing has to be cleared or subordinated there too. Coverage clears at 1.00 on select programs, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, and management sit outside the ratio. For a closer look at the line product, Lendmire’s look at the best investment property HELOC program with a solar lien or an unpermitted ADU compares how the pieces fit together.

Mistakes That Cost Investors a Line

• Treating a UCC-1 as paperwork. It can muddy title, and many title companies want it gone.
• Skipping the UCC-3. Paying off the loan does not clear the filing until the termination is recorded.
• Trusting an automated value. It cannot see permits, so the number may not hold up later.
• Counting ADU rent. A HELOC does not use rent, and rent-based loans generally exclude unpermitted units.
• Assuming a signed subordination is enough. Only a recorded one counts.
• Ignoring vesting. An LLC-titled rental cannot take this line.
