The Quick Read: A solar lien or an unpermitted ADU rarely ends a rental-property equity line on its own, but each one changes the file differently. A recorded solar lien or a tax-assessed solar loan uses up combined equity. An unpermitted ADU can cut appraised value and remove its rent from the picture. Both problems are fixable in most cases, but the order of the fixes matters.
- On this network, an investment-property line tops out at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
- Solar is not one thing. A recorded solar mortgage or a tax-bill assessment counts against your equity, while an equipment-only filing usually does not.
- An unpermitted ADU is a value and legality problem, not a title problem. Plan on its square footage and rent not counting.
- The line must be vested in you personally or in a revocable living trust, so a property held in an LLC needs a different route.
- Treatment varies by lender and file, and every figure here is subject to lender guidelines.
What Does a Rental HELOC Ask For Before Solar or an ADU Enters the Picture?
A rental-property equity line is underwritten on the property’s liens first and on you second. On the wholesale network Lendmire places these files with, an investment line caps at 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000. Those limits are the frame everything else sits inside.
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.
Lendmire is a mortgage broker, not the lender. It arranges these lines through select wholesale partners, and the lender reviews every file. Here is what an investment-property line typically looks like on this network:
- Structure: a standalone line in first or second lien position, with a 5-year interest-only draw period and then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing.
- Credit: 700 is a hard floor, and a 720 score does not buy more leverage. The report is single-bureau, no more than 90 days old, and no rescores are allowed.
- Debt-to-income: 50% maximum, qualified on the interest-only payment at the maximum draw.
- Property types: single-family, 2-4 units, PUD, townhome and condominium, including non-warrantable condos. Manufactured homes, log homes, co-ops, condotels, commercial, mixed-use and agricultural zoning are not offered.
- Limits on you: no more than three lines, and a borrower with more than 15 financed properties is not eligible.
- Credit history: a bankruptcy needs 4 years of seasoning. A foreclosure follows a 7-year path, and a deed-in-lieu, pre-foreclosure or short sale follows a 4-year path.
The line is offered only in Lendmire’s 16 full-service states. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C. For a side-by-side with DSCR financing, see the complete DSCR loans guide.
NerdWallet notes that investment-property lines are harder to get than lines on a primary home. It cites a smaller pool of lenders and smaller borrowing amounts. That matches what you see when you shop the category.
Is a Solar Lien Always a Lien?
No. “Solar lien” covers four different instruments, and the title search tells you which one you have. Each one hits your usable equity differently, so classify yours before you talk to any lender.
| Solar item | Where it sits | Effect on CLTV | Typical fix |
|---|---|---|---|
| UCC-1 on equipment | Public notice on the panels | Usually none | Payoff, then a recorded UCC-3 |
| UCC-1 fixture filing | County land records | Usually none, but it clouds title | Payoff, then a recorded UCC-3 |
| Solar mortgage or deed of trust | Recorded junior lien | Counts in full | Payoff and recorded release |
| PACE assessment | Property tax bill | Counts, and ranks ahead of mortgages | Pay off the assessment |
An equipment-only filing is a notice of a security interest in the panels, not in the land. Solar.com explains that leased and power-purchase-agreement filings cover the system and not the home. It adds that the filing can be removed and later refiled if the system is refinanced.
A fixture filing is the same idea recorded in county land records. Because panels can be treated as fixtures, a routine title search finds it. It does not legally cover the land, but it reads like a cloud on title, so more lenders push back on it.
A recorded solar mortgage is different. It is a true junior lien, and it counts in your combined leverage just like a second mortgage would.
An unsecured solar loan records nothing on title. It matters only as a monthly obligation in your debt-to-income ratio, which this line does check.
Why Does a PACE Assessment Cause the Most Trouble?
PACE stands for Property Assessed Clean Energy. It is repaid through the property tax bill. In most states it ranks ahead of the mortgages on the home, though priority varies by state. A UCC-3 cannot clear it, because it is not a filing. It has to be paid off, or in rare cases subordinated.
The Federal Housing Finance Agency has long objected to this structure. Its notice in the Federal Register describes PACE as enabled by state law, with priority over existing and later first mortgages at a tax or foreclosure sale. That priority is why lenders treat it as the worst case.
Equity lines are not agency products, so that notice does not govern this line directly. The practical point is that a lien with this kind of priority makes lenders cautious, and you should expect a private lender to react the same way.
If you suspect PACE, check the property tax bill first, where an assessment appears as its own line.
How Does an Unpermitted ADU Change the File?
An unpermitted accessory dwelling unit is mostly a value and legality issue, not a title issue. Expect the unit’s square footage not to count in value, and expect its rent not to count either. How a lender treats it still varies by program.
Valuation comes first. Gather ADU explains that appraisers generally will not credit unpermitted square footage. Many treat it as zero value, and some treat it as a liability.
Here is how the common ADU situations play out:
| Situation | Value effect | Rent effect |
|---|---|---|
| Permitted ADU | Can support value, subject to comps | Can count, subject to lender review |
| Unpermitted, rented | Often zero credit | Typically not relied on |
| Unpermitted, vacant | Often zero credit | None to count |
Rent is the second issue. Signed leases and deposit records show the unit is occupied, not that it is legal. Occupancy by a paying tenant therefore does not turn the rent into income a lender will rely on.
The valuation lane on this line adds a twist. An investment line stops at $500,000, and full appraisals begin only above that amount. So an investment line normally runs on an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation, and you can request a full appraisal in any case.
An automated model does not walk the property. The permit question can still come up in the lender’s property review, in the insurance file and at any later sale. Do not count on the model missing it.
The line itself is underwritten on your personal debt-to-income ratio, not on rent coverage. That means the ADU rent matters less on this product than it would on a DSCR loan. It matters more if the rent is helping you carry your other debts.
Lenders do not all treat unpermitted units the same way. One lender may finance the main house and ignore the ADU, while another declines the whole file because of an overlay. Ask early, before you pay for anything.
What Happens When Both Problems Show Up Together?
When both problems are present, they stack, and they hit equity from two sides. The solar lien takes away usable equity, and the ADU lowers the value that the equity is measured against. Run the combined math before you apply.
Here is a modeled example, using assumed values and not market data. Treat the property’s value as 100 points.
- Baseline: the cap is 70% of value, or 70 points. With a first mortgage at 48 points and a recorded solar deed of trust at 7, existing liens total 55. That leaves 15 points of room for the new line.
- Solar paid off and released: existing liens drop to 48, leaving 22 points of room.
- ADU value stripped, solar still in place: value falls to 90, so the cap becomes 63 points. With liens at 55, only 8 points remain.
- ADU value stripped, solar cleared: the cap is 63 and liens are 48, leaving 15 points.
The takeaway is simple. Clearing the solar lien recovers 7 points. Losing the ADU value also costs 7 points, because the cap drops from 22 points of room to 15 even with the solar lien gone. The line size also cannot exceed $500,000 on any version of this file.
This is also where a tax-bill assessment hurts most. A PACE balance sits ahead of your new line, so it must be paid off or the line sits behind it.
What Order Should You Fix Things In?
Fix the solar item first. It is cheaper, it is mostly paperwork, and it sets the CLTV you are working with. Legalizing an ADU is a longer project that depends on your local building department. The steps below follow that logic.
1. Pull a title report and run a UCC search. Run both a state-level search and a county search. Classify each solar item as an equipment filing, a fixture filing, a recorded mortgage, a PACE assessment or nothing on title.
2. Check the tax bill. A PACE assessment appears there as its own line.
3. Resolve the solar item. For a UCC-1, pay off or buy out the system, then get a UCC-3 termination recorded. Only the secured party can file it, so you may need an attorney if the solar company will not cooperate.
4. Re-run the search. Confirm the termination actually appears in the record. Good Shepherd Energy recommends this step. Budget time for it.
5. Decide what to do about the ADU. Choose between legalizing it, leaving it out of the equation or removing it. Do not count its value or rent until it is permitted.
6. Confirm vesting. The property must be titled in you personally or in a revocable living trust.
7. Then apply. Ask for a pre-review before you pay for valuation or title work.
What Documents Should You Gather First?
Collect these before you apply, because each one closes a question the lender would otherwise ask:
- A current title report showing every recorded lien
- Solar contract, payoff letter and any recorded UCC-1, UCC-3 or deed of trust
- The latest property tax bill, with any assessment lines visible
- Insurance declarations for the main house and any ADU
- Permit records, or a written statement that none exist
- A deed showing how the property is vested
- Your credit information and debt schedule across all financed properties
Can Your LLC Hold This Line?
No, not on this product. Title must be held by you as an individual or by 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 before the line is possible, or it needs a different product.
When Should You Switch Products?
Stop chasing the equity line when the limits above cost you more than they give. A $500,000 cap, a 70% ceiling and a personal-vesting rule are real constraints. If the file cannot work inside them, a DSCR cash-out refinance may fit better.
| Factor | Investment-property line | DSCR cash-out refinance |
|---|---|---|
| Max leverage | 70% CLTV on an investment property | Around 75% LTV on a standard-rental cash-out |
| Size | Up to $500,000 | Up to $3,000,000 on standard programs |
| Reviewed on | Your credit and debt-to-income | Property rent against the full payment |
| Entity | Individual or revocable trust only | LLC allowed, subject to lender program eligibility |
| Credit | 700 minimum | A 620 floor exists in parts of the network; most want about 660 |
| Position | First or second lien | Replaces the existing loan |
A DSCR cash-out generally expects about 6 months of seasoning. Coverage of 1.00 is where select programs start, and stronger ratios can open better terms and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. The DSCR ratio compares rent to the full monthly obligation only. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy and management sit outside it.
Do not assume an unpermitted ADU will pass on a DSCR file. Select lenders differ, and rent from an unpermitted unit typically cannot be counted toward coverage. A solar lien still comes out of equity either way, whichever product you choose.
For the program-fit angle, see which line program fits a rental with a solar lien or an unpermitted ADU.

Frequently Asked Questions
Does a solar lease or power purchase agreement block an investment property HELOC?
Usually not on its own. The provider may file a UCC-1 on its own equipment, which is not a lien on the home. Lenders still look at it, and a fixture filing in county records can draw more questions than an equipment-only filing. Treatment varies by lender.
Does a solar payment count against my debt-to-income ratio?
Yes, if the solar loan is unsecured or covered only by an equipment filing, the payment still counts as a monthly debt. This line allows up to a 50% ratio, qualified on the interest-only payment at the maximum draw. A recorded solar lien counts in your combined leverage as well.
Can the solar company subordinate its lien?
Sometimes. A recorded solar lender may agree to sit behind the new line, but it is not required to, and many will not. Payoff and release is the more reliable fix, and it removes the question entirely.
Will an unpermitted ADU make the lender decline the whole file?
It can, depending on the lender’s overlays. Some lenders ignore the ADU and finance the main house. Others decline the file outright. Because a rental line of this size normally runs on an automated valuation, the unit may not be caught by the model, but it can still surface in the property review or insurance file.
Can I count rent from an ADU I rent out today?
Typically not if the unit is unpermitted. Leases and bank deposits show occupancy, not legality. On a line underwritten on your personal debt-to-income ratio, leave the rent out of your own math unless the unit is permitted.
What if my property is in an LLC?
It needs a vesting change to you or a revocable living trust, or a different product. A DSCR cash-out refinance can work with an LLC, subject to lender program eligibility.
Whichever route you take, clear the title before you choose the product, because a lien you can see now is far cheaper to fix than one a lender finds later.
