The Quick Read: It depends on which problem you have, because an active solar lien on the rental makes the property ineligible, so the line is $0 until the lien is paid off and released, while an unpermitted ADU is left out of both rent and value, so the line is sized on the main house alone.
- Solar lien: not a haircut. The line is unavailable until the lien is paid off and the release is recorded.
- Unpermitted ADU: the main house carries the whole file, on its own value and its own rent.
- Your ceiling: 70% combined loan-to-value on a second lien at a 720 score or better, on lines of $50,000 to $500,000, subject to underwriting.
- Coverage test: 1.10x minimum, measured on a stress payment over the entire line.
- Fix order: clear the solar filing first, settle the ADU question second, then apply.
A DSCR HELOC is a home equity line on a rental, qualified on the rent instead of your personal income. Across the wholesale network where Lendmire places these files, the program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. The rules below are ceilings and floors, not offers. Every file is underwritten individually.
Your Max Line, in One Formula
Your maximum line is the lesser of three limits. The first is the equity limit: appraised value of the main house times the leverage cap, minus what is already recorded against it. The second is the program limit, which is $500,000 on a second lien. The third is the coverage limit, because the rent has to clear 1.10x on the whole line.
On a second lien, “recorded against it” means your first mortgage plus any solar mortgage still on title. If the room left is under $50,000, there is no line to write, since the program starts at $50,000. Because at least 80% of the line is drawn at closing, the line you are approved for is largely the amount you borrow on day one, even though later draws remain available on the revolving line.
The two problems hit different inputs. Solar sits outside the math and sets the line at $0 until the lien is cleared. The ADU works inside the math, taking rent and value out of the inputs.
What Is a DSCR HELOC, and Where Does Leverage Stop?
A DSCR HELOC is a revolving line written as a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien on a rental with no mortgage. The rent qualifies it, and the LLC can stay on title, subject to program terms. For a deeper walk through how these loans work, see Lendmire’s complete DSCR loans guide.
Here are the leverage tiers on an investment property, through select programs and subject to underwriting:
| Position | Score | Max leverage | Line size |
|---|---|---|---|
| Second lien | 720+ | 70% CLTV | $50,000-$500,000 |
| Second lien | Below 720 | Not offered | N/A |
| First lien, no mortgage | 740+ | 75% LTV | Up to $500,000 |
| First lien, no mortgage | 700-739 | 70% LTV | Up to $500,000 |
| First lien, no mortgage | 720+ | 65% LTV | $500,000-$1,000,000 |
The coverage test comes next. Gross monthly rent divided by the qualifying payment must reach 1.10x. That payment is a fully amortizing payment on the entire credit limit at a stress rate, not on what you draw. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. If you have a first mortgage, confirm on the file how the lender treats that payment in the coverage calculation.
Three file rules matter for what follows. Lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Waivers are not accepted. And a rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
How Does a Solar Lien Change the Line?
An active solar lien takes the line to $0. Across the network, a rental with a solar lien is outside the program, so there is no reduced version to negotiate. Once the lien is paid off and released, the standard leverage grid applies.
The reason is title. Lenders often file a UCC-1 on the panels themselves. The CFPB’s issue spotlight on solar financing notes that such a lien is technically not on the property but can muddy title, since some jurisdictions treat it as reaching the whole property. A second-lien lender sitting behind your first mortgage will not take that risk on a file where the title is unclear.
Not every solar arrangement is the same. Each one leaves a different mark and clears a different way:
| Arrangement | What is on record | Clears by |
|---|---|---|
| Owned outright | Nothing | Nothing to clear |
| Solar loan | State UCC-1 on equipment | Payoff, then UCC-3 |
| Solar loan with fixture filing | County land records | Payoff, then UCC-3 |
| Solar deed of trust | Recorded mortgage | Payoff and release |
| Lease or PPA | Provider’s UCC-1 | Confirm program fit first |
| PACE | Tax assessment | Payoff, usually |
Two traps catch owners here. First, paying the loan does not remove the filing. A UCC-3 termination has to be recorded as well. A title-industry practitioner describes three clearing paths: payoff and termination, a lease transfer with provider consent, or subordination of a fixture filing. Whether subordination alone satisfies this program is a question for the lender before you order anything.
Second, a plain state-level UCC-1 may not show up in a county title search. A fixture filing is recorded in county land records and does show up. Run a UCC search as well as a title report.
PACE is the hardest case. PACE repayment is secured by a property tax lien, and Mayer Brown’s summary of the federal PACE rule notes that lien takes priority over existing and future mortgages. A UCC-3 does not clear a tax assessment. Payoff is the usual route.
A leased system adds a different wrinkle. The equipment belongs to the provider, so it typically adds no appraised value. Confirm how the program treats the provider’s filing before you spend money on an appraisal.
One more point on math. A recorded solar deed of trust counts toward combined leverage. Paying it off frees both the lien problem and that slice of CLTV room, but it also costs you cash.
What Happens to the Line With an Unpermitted ADU?
The appraiser decides how the ADU is treated, and the lender follows the appraisal. A unit with no permit is generally left out of both value and rent. The main house then has to carry the file by itself, and the line is sized on the main house’s value and rent only.
The 1.10x test therefore runs on main-house rent. Market rent comes from the appraiser’s rent schedule, Form 1007 on a single-family home and Form 1025 on a two-to-four-unit property. An unpermitted unit cannot be supported on those forms. That leaves the lender with no third-party income documentation for it.
Collected rent does not override this. Your tenant may pay on time every month, and the legal-use analysis in the appraisal still outranks the rent roll.
This is the effect of permit status on the three inputs:
| Input | Permitted and finaled | Unpermitted |
|---|---|---|
| Rent in coverage test | Can count | Generally excluded |
| Value in leverage | Can count | Generally excluded |
| Appraiser notes | Routine | Often flagged, sometimes a repair condition |
A permitted but not finaled unit sits in between. Rent is often excluded until the unit is finaled, and the appraiser may condition the report.
Leaving the unit out of the numbers does not make it harmless. Appraisers generally note an unpermitted structure and assign it little or no value, and in some cases it can lower the main property’s value. Treat the ADU as upside, not as part of the base case.
Three Properties, Side by Side
Run the numbers on a rental with a second lien in mind. All figures below are modeled assumptions in percentages and ratios, not market data, and the lender’s own calculation governs. Assume the first mortgage sits at 45% of appraised value and the cap is 70% CLTV on an investment property.
| Step | Clean | Solar only | Solar plus ADU |
|---|---|---|---|
| Line today | Open | $0 | $0 |
| After solar release | N/A | Open | Open |
| Equity room (cap minus first) | 25% of value | 25% of value | 25% of the lower main-house value |
| Coverage test | Full rent | Full rent once the solar lien is released | Main-house rent only |
Walk through the third column. The solar lien is cleared first. The appraiser then values the main house alone, so the 70% cap applies to a smaller number and the room shrinks in dollars even though the percentage is the same. Next, coverage is rerun. A file that clears 1.10x with the ADU rent can land near or below 1.00x without it. That is an illustrative ratio, not a prediction.
If coverage falls short, the options are a smaller line, which lowers the stress payment, or a different product. Whether either one fits depends on lender guidelines, credit approval and property review.
Capacity can also vanish in one step. If a solar payoff eats your cash, or the ADU removal pushes the room under $50,000, there is no line at that property.
Fix First, Apply Second
The order matters because each step changes the next one’s inputs.
1. Pull the title report and run a UCC search. Know exactly what is recorded before you do anything else.
2. Classify each solar item. Owned, loan, fixture filing, deed of trust, lease or PPA, or PACE.
3. Gather the paperwork. You need the contract, the UCC-1 and any fixture addendum. For PACE, add the agreement, the tax statement and a payoff statement.
4. Pay off and confirm the UCC-3. Check the recorded termination, not just the payoff letter.
5. Decide on the ADU. Either legalize it, or underwrite the property on the main house alone.
6. Rerun the coverage test on main-house rent, then ask the lender what the valuation will count before paying for one.
Legalization can turn lost rent and value into usable income, but the route varies by place. California is one example. California’s housing department describes a program for legalizing unpermitted ADUs built before a statutory cutoff date. Most places have no equivalent, and a unit that fails health and safety standards may not qualify even where one exists.
Treat legalization costs as a reason to get a local quote, not as a number to plan around. An improvement may support a higher appraised value, depending on comps and underwriter review.
When a Different Product Fits Better
If the fixes will take a while or the equity is too thin, a different product may fit better. These are other programs with their own rules, not features of this one:
| Option | Reviewed on | Fit |
|---|---|---|
| DSCR cash-out refinance | Rent | Replaces the first mortgage |
| Bank statement HELOC | Documented deposits | Personal-income file |
| Investment-property HELOC | Personal income | Traditional documentation |
| Wait and legalize | N/A | Repairs the inputs first |
Each still sees the solar filing in title and the ADU in the appraisal, since those are facts about the property. The product changes the income test, not the property’s problems.
Key Terms Defined
DSCR: debt service coverage ratio. It is gross monthly rent divided by the qualifying monthly payment.
CLTV: combined loan-to-value. It is the first mortgage balance plus the new line, divided by property value.
UCC-1: a public notice that someone has a claim on equipment, such as solar panels.
UCC-3: the filing that terminates a UCC-1. Payoff alone does not replace it.
Fixture filing: a UCC-1 recorded in county land records, so it appears in a title search.
Subordination: a notarized agreement where the solar creditor agrees to rank behind the new lender.
PACE: a clean-energy assessment collected through the property tax bill.
ADU: accessory dwelling unit, a second small home on the same lot or inside the main house.
Frequently Asked Questions
Can the line pay off the solar balance?
No. Under the network’s rule, a property with a solar lien is ineligible, so the lien has to be released before you apply. Your payoff source is cash or another loan. Then confirm the UCC-3 is recorded so title shows clean.
Does the rent I collect from the ADU ever help?
Not when the unit is unpermitted. The appraiser’s legal-use analysis controls, and the lender follows the appraisal. Collected rent can help in a permitted and finaled unit, where the appraiser can support it on the rent schedule.
Is a subordination agreement enough for a solar filing?
Possibly for some programs, but ask first. Subordination is a notarized agreement, and providers may charge for it. On this program, a property with a solar lien is ineligible, so put the question to the lender before ordering anything.
Can I legalize the ADU and then apply?
Yes, where your area offers a path. After the unit is permitted and finaled, a new appraisal can address legal use. The 6-month seasoning and title rules above still apply, so check your dates against them.
What should I ask before paying for an appraisal?
Ask what the lender will count. Is the ADU excluded from rent and value? How does the lender treat a lease or PPA filing? Confirm on the file how the lender treats the first-mortgage payment in the coverage calculation. The answers decide whether the appraisal is worth ordering.
