The Quick Read: It depends on occupancy, credit profile, and which solar instrument is recorded, because the limit is a formula: property value times the lender’s combined loan-to-value cap, minus your first mortgage and any solar debt that counts as a lien, then held to the program’s maximum line. Closing-cost geography changes your net cash, not the formula.
- On an investment property, the ceiling across Lendmire’s wholesale network is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a maximum line of $500,000.
- On a primary residence or second home, the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile.
- A recorded solar mortgage or deed of trust uses up room dollar for dollar. A tax-assessment solar lien generally has to be paid off.
- High closing costs and a solar payoff shrink the cash that lands in your account. They do not move the CLTV cap.
- Everything here is subject to lender guidelines and full file review. This is not a commitment to lend.
What Is the Formula for the Maximum Line?
The maximum line is value times the CLTV cap, minus every lien that counts, held to the program’s top line size. Start with current market value, not what you paid. Apply the cap for your occupancy and credit tier. Subtract the first mortgage and any solar debt that is recorded as a lien. Whatever remains is your equity room.
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.
Then the program’s dollar cap steps in. You get the lesser of the two numbers.
Here is a modeled example, using percentages only. These are assumptions, not market data.
- Assume a rental with a first mortgage equal to 45% of value.
- Assume a recorded solar loan equal to 8% of value.
- On an investment line with a 70% CLTV ceiling, those two liens already use 53% of value.
- That leaves 17% of value as room for the new line.
- If 17% of value comes to more than the $500,000 investment-line cap, the cap binds first. If it comes to less, the equity binds first.
Run it with the solar loan removed, and the room grows to 25% of value. That is the whole story of what a solar lien does: it takes equity you could have borrowed against.
Market surveys often describe about 85% of value as a typical limit on owner-occupied lines, per the BiggerPockets HELOC glossary. That is a market-wide rule of thumb, not a network figure. On this network, an investment-property line tops out at 70% CLTV, and a primary residence or second home reaches 90% CLTV only at a 720-or-better credit profile.
What Does Each Occupancy Allow?
The ceiling depends on how you use the property. Credit tier and occupancy set the CLTV, and the network’s line caps differ by occupancy too. These are typical ranges from select lenders in the network, not guarantees.
| Occupancy | Top CLTV | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% | 700 minimum | $500,000 |
| Second home | 90% | 720+ for 90% | $500,000 |
| Primary residence | 90% | 720+ for 90% | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
A primary-residence line can exceed $500,000 only with a credit profile of 700 or better (720 on the longer-runway program). Such a line is capped at 75% CLTV and requires a full appraisal. Investment lines never pass $500,000.
Credit moves the numbers further down the ladder. A second home at 640 tops out at 75% CLTV. A primary residence at 620 tops out at 70% CLTV with a smaller line. Investment property has one gate: a 700 score, which gives you the 70% cap.
A few other rules matter for rental owners:
- Title must sit with you personally or in a revocable living trust. An LLC, a corporation, or a land trust cannot hold title on these lines.
- The line is a standalone product in first or second lien position.
- A borrower can carry up to three of these lines, and owning more than 15 financed properties makes you ineligible.
- Manufactured homes, log homes, condotels, and mixed-use properties are not offered. Single-family, 2-4 units, townhomes, PUDs, and condominiums, including non-warrantable, are eligible.
- The product is available in 16 states, a narrower footprint than Lendmire’s DSCR platform.
Not All Solar Liens Are the Same
“Solar lien” covers at least five different instruments. They behave differently, and your line depends on which one you have. A federal regulator’s Issue Spotlight on solar financing explains that lenders commonly file a UCC lien on the panels themselves. That lien is technically not on the property, but it can muddy title because some jurisdictions treat it as applying to the whole property.
The same report notes that some solar loans are secured while others are unsecured. Here is how each type tends to play out.
| Instrument | Where it sits | Counts in CLTV? | Usual path |
|---|---|---|---|
| Owned outright | No filing | No | Nothing to clear |
| Lease or PPA | UCC-1 on panels | No balance | Consent, transfer, or termination |
| Solar loan, UCC-1 only | State or county filing | Often reviewed case by case | Payoff or title confirmation |
| Recorded deed of trust | County land records | Yes | Payoff or subordination |
| PACE assessment | Property tax bill | Yes, and it ranks first | Full payoff |
| Unsecured solar loan | No lien | No lien, but payment may count in DTI | None |
Two points deserve emphasis.
First, a recorded deed of trust is a real lien. It sits in your CLTV math exactly like a second mortgage.
Second, a PACE assessment is the hard case. A Mayer Brown analysis of the federal PACE rule describes it as a lien that takes priority over existing and future mortgages. A new lender will not want to sit behind it. Plan on paying it off, and confirm the details of your specific assessment with your PACE administrator and a qualified local professional.
Does the Solar Payment Count in My Debt Ratio?
On a HELOC, yes, it can. This is where a HELOC differs from a rental loan. These lines review your personal debt-to-income ratio (DTI), which is your monthly debts divided by your monthly income. The maximum is 50%, and the line is qualified on the interest-only payment calculated on the maximum draw.
A solar loan with no lien still carries a monthly payment, and that payment can count against your DTI. A lease payment can too. So even where a UCC-only filing leaves your CLTV untouched, it may still hit your ratio.
A DSCR loan reads the file differently. DSCR means debt service coverage ratio: the rent divided by the property’s full monthly obligation (principal, interest, taxes, insurance, and any HOA dues). It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A solar payment on your home is not the test there. Coverage on the subject rental is.
Can the HELOC Pay Off the Solar Loan?
The payoff comes out of the closing draw, which means two numbers must fit together. At least 75% of the line is drawn at closing on both wholesale programs. If your solar payoff is bigger than that first draw, the file does not close as structured.
So the useful number is not the line size. It is this:
- Equity room under the CLTV cap, held to the line cap.
- Minus the solar payoff.
- Minus closing costs.
- Equals the cash you can actually use.
That last figure is the one investors forget to calculate.
Sequence matters. Order a title search and a separate UCC search first, because a standard county title search may not surface a state-level filing, as a real estate investor’s closing guide points out. Get a payoff letter. Then confirm the termination is actually filed. Paying the loan does not clear the record automatically. The secured party must file a UCC-3 termination.
A title agent’s guide to clearing fixture filings lists three clearing paths: payoff and termination, a lease transfer with the provider’s consent, or subordination to the new mortgage. Subordination is negotiated, not a right. And a UCC-3 does not clear a PACE assessment. That takes full payoff.
Why High-Cost Closing States Change Your Net, Not Your Limit
Closing costs vary widely by state, and in the expensive ones they cut into what you pocket. They do not change how much equity the lender will count. Transfer taxes, recording taxes, attorney requirements, and title premiums drive the spread.
The National Association of Realtors summarized a study showing state averages ranging from 1.2% to 2.47% of a home’s value. That is a purchase-cost estimate and it is dated, so read it as a sense of the spread. No state-by-state HELOC figure is published that we can cite, so budget by getting a written cost estimate early.
Two practical effects show up in a high-cost state:
- Title and recording charges on the solar payoff and the new lien come out of your proceeds.
- A thin equity cushion gets thinner. If your room is already small after the solar balance, costs can leave very little usable cash.
This is the point where the payoff-versus-subordination choice gets real. If the solar provider will subordinate, you may avoid paying off a balance you were happy to keep. If title will not accept that, payoff is the cleaner route. A seasoned broker looks at both before telling you the line is worth doing.
When the Solar Lien Stops the Line Cold
Several situations shrink your line, and a few stop it outright.
- PACE. Generally has to be paid off first.
- A fixture filing title will not clear. A county-recorded fixture filing shows on the title commitment, and the title company may require a payoff, a consent, or a subordination. In some cases a title company confirms in writing that a fixtures-only filing can stay. That is a case-by-case outcome, not a rule.
- A lease or PPA with no consent. There is no balance to count, but the provider may need to sign off before title moves.
- A property listed for sale or listed in the past 60 days. It is ineligible in several states on the network’s list.
- A property already deeded to an LLC. The line needs a vesting change first.
On the other side, an owned-outright system carries no filing, and an unsecured solar loan carries no lien. Those clear the title test. You still face the DTI test.
Decision Table: Pay Off, Subordinate, or Wait?
Pick the path by what the instrument is and how much room you have left.
| Situation | Usual best move |
|---|---|
| Recorded deed of trust, ample equity | Pay it off inside the closing draw |
| UCC-1 only, title will confirm in writing | Ask title to let it remain |
| Lease or PPA | Get provider consent or a buyout |
| PACE assessment | Pay it off in full |
| Thin equity after solar | Wait, or look at a different structure |
The question to ask first is not how much can I borrow. It is how much of my equity is already spoken for.
Where a HELOC Is the Wrong Tool for a Rental
A HELOC is not built for most rental investors. The investment-property ceiling is 70% CLTV, the line caps at $500,000, and you need a 700 credit score. Pricing floats during both the interest-only draw and the repayment period and never converts to fixed. Title must stay in your name or a revocable trust.
Investor commentary on BiggerPockets suggests investment-property lines are scarce and carry reserve expectations. That is anecdotal and dated, but it fits what you see in practice.
So when does a DSCR cash-out refinance make more sense? Think about three situations.
- The rental is in an LLC. A DSCR loan can close in an entity, subject to lender program eligibility. A HELOC cannot, without a vesting change.
- You want to clear a solar filing and replace the first lien in one move. A cash-out replaces the first mortgage, so any solar filing must be cleared or subordinated to put the new lender in first position.
- You need more than the line cap allows. DSCR loans typically reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
For a standard rental, cash-out refinances typically top out around 75% LTV, with about 6 months of seasoning as the common expectation. Short-term-rental collateral usually lands lower at around 70% on a cash-out. Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing the ratio is not the same as positive cash flow, because repairs, vacancy, management, and capex sit outside the calculation.
Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Larger loans typically step up from there. Credit floors run from a 620 floor in parts of the network to most programs wanting around 660, with 700 or higher unlocking the strongest leverage. Qualifying documentation for DSCR files runs on the applicable program, not a personal income test.
Our complete DSCR loans guide lays out the program ranges in one place.
Key Terms Defined
CLTV (combined loan-to-value): All liens on the property added together, divided by its value. It includes your first mortgage and the new line.
UCC-1: A public notice filed against equipment, such as solar panels, to show who has a financial interest in it.
UCC-3: The filing that ends a UCC-1. Proof of payoff means this termination is on record.
Fixture filing: A UCC-1 recorded in the county land records against the property, so it shows up in a title search.
PACE assessment: A home-improvement financing repaid through your property tax bill. It sits ahead of mortgages in priority.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income. HELOCs review it. DSCR loans read the property’s rent against its payment instead.
Frequently Asked Questions
Does a solar lien reduce how much I can borrow on a HELOC?
Only when it is a recorded lien that counts in CLTV. A solar mortgage or deed of trust takes room dollar for dollar. A lease or PPA has no balance to count. A UCC-1 on the panels may not count in CLTV, but title can still require action before the line funds.
Can a HELOC pay off my solar loan?
Often, yes, as long as the payoff fits inside the first draw. At least 75% of the line is drawn at closing on both wholesale programs, so the payoff must come out of that. The leftover equity and the net cash after closing costs are the numbers that decide whether the move is worth it.
Does a high-cost closing state lower my HELOC limit?
No. The limit is value times the CLTV cap, minus liens, held to the line cap. High transfer, recording, and title charges reduce the cash you actually receive. They do not change the formula. Get a written cost estimate before deciding whether a payoff is worthwhile.
Can I get a HELOC on a rental held in an LLC?
Not as titled. These lines require the individual borrower or a revocable living trust on title, and an LLC cannot hold it. A property already in an LLC needs a vesting change first, or a DSCR cash-out refinance, subject to program terms.
What is the maximum CLTV on an investment property line?
70% CLTV across the network, with a 700 minimum credit score and a maximum line of $500,000. The 90% ceiling applies only to primary residences and second homes at a 720-or-better credit profile. Every figure is subject to lender guidelines and file review.
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals.
