The Quick Read: The highest ceiling depends on how the property is used before anything else: across Lendmire’s wholesale network, a primary residence or second home can reach 90% combined loan-to-value only at a 720 or better credit profile, while an investment property stops at 70% regardless of score. Lendmire is a mortgage broker, not a lender, so it matches your file to the wholesale lender whose program fits.
Key takeaways
- Occupancy sets the ceiling first. Credit tier, line size, and state overlays adjust it afterward.
- On a primary residence or second home, 90% combined loan-to-value is available only at 720+ credit, on lines up to $500,000. A primary-residence line above $500,000, up to $750,000, caps at 75% and needs a 700 or better credit profile (720 on the longer-runway program).
- On an investment property, the ceiling is 70% combined loan-to-value, a $500,000 maximum line, and a 700 minimum score. No higher tier exists.
- The usable line is the smallest of three limits: equity room, the program’s dollar cap, and your debt-to-income capacity.
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.
What Combined Loan-to-Value Means
Combined loan-to-value (CLTV) is every lien on the property, including the new line, divided by the property’s value. Say a home is worth 100 and the first mortgage is 55% of that. A 70% ceiling leaves room for a line worth 15% of value. A 90% ceiling leaves room for 35%.
That difference is why the “highest available” question has no single answer. The ceiling is the lender’s own policy for the occupancy class, the credit tier, and the line size. No single national number applies.
Value here means the lender’s value, set by an automated valuation or an appraisal. It is not an online estimate. The two can differ by more than borrowers expect.
How Underwriting Treats a High-CLTV Line, Step by Step
1. Value is established. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal in any case.
2. The ceiling is picked. The lender selects the CLTV cap for primary, second-home, or investment use, then adjusts for credit tier and line size.
3. Room is calculated. Value times the ceiling, minus all existing liens, gives the maximum line.
4. The full limit counts. Many lenders measure CLTV against the whole credit limit, not just the drawn balance. A line sized “for later” uses up room today. Practices differ, and a few lenders measure only the drawn amount.
5. Three limits, lowest wins. Your usable line is the smallest of the CLTV room, the program’s dollar cap, and your debt-to-income capacity.
6. Qualification runs on an interest-only payment. Underwriters calculate it on the maximum draw, not on what you plan to borrow. A 50% debt-to-income maximum applies, but profiles from 600 to 679 are held to 45%. Any ratio above 45% requires a score of at least 680.
7. Most of the line is drawn up front. On the programs in the network, at least 75% of the line is drawn at closing. Pricing floats during both the draw and repayment periods and never converts to fixed.
That last point surprises people. A HELOC through this network behaves more like a standalone second mortgage than a card you leave unused.
Where the Ceilings Sit by Occupancy
Occupancy sets the ceiling, and credit moves you within it. The figures below are typical ranges from select wholesale-network guidelines, subject to lender guidelines and full file review.
| Occupancy | Top CLTV | Credit needed | Line size |
|---|---|---|---|
| Primary residence | 90% | 720+ | Up to $500,000 |
| Primary residence (larger line) | 75% | 700+ (720 on the longer-runway program) | Up to $750,000 |
| Primary residence | 85% | 660 to 719 | Up to $500,000 |
| Second home | 90% | 720+ | Up to $500,000 |
| Investment property | 70% | 700+ | Up to $500,000 |
On a primary residence, the lower tiers continue downward: 80% CLTV at 640+, 70% at 620+ and 60% at 600+, with the lowest two tiers capped at $400,000. A primary-residence line above $500,000 caps at 75% CLTV and requires a full appraisal. Its credit requirement is 700 or better (720 on the longer-runway program, described below).
Second homes floor at a 640 score, with 75% CLTV at that level. Investment properties floor at 700. That means the sub-640 options some primary-residence borrowers see do not reach rentals.
A score above 700 does not raise the investment ceiling. It only keeps the file eligible. Borrowers who expect a 760 to unlock 80% on a rental will not find it in this network.
Structures and Variations
Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year amortizing repayment. The longer-runway program has a 5-year draw followed by a 25-year repayment. Investment lines run only the 5-year/25-year structure. Tennessee shortens both structures.
Other mechanics worth knowing:
- Lien position. The line can sit in first or second position as a standalone product.
- Line size. Lines run from $25,000 to $750,000, with a lower floor in Michigan. Anything above $500,000 is primary-residence only.
- Later draws. On the longer-runway program, a subsequent draw after closing has a $1,000 minimum, with a higher minimum in Texas.
- Property types. Single-family, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable) are eligible. Modular factory-built homes are eligible on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not offered.
- Availability. HELOC placement runs in 16 full-service states, which is narrower than the 41-market DSCR footprint.
Where the General Rule Breaks
Rental lines are scarce in the wider market. An investor in a BiggerPockets thread on rental-property HELOCs describes a line as possible but offered by few banks, with a single-property cap at one of them. That matches the pattern across the wholesale network: lenders that will take a rental line are a short list, and the ceiling is lower than on a home you live in.
Title blocks LLC-owned rentals. The borrower must hold title individually or in an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
Listed properties are ineligible in certain states. A property listed for sale, or listed within the past 60 days, is ineligible in several states. Even elsewhere, a sale generally requires paying the line off in full, as the CFPB’s HELOC brochure explains.
Credit history can shut the door. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history splits by program on primary residences and second homes. One program seasons a foreclosure at seven years and a deed-in-lieu, pre-foreclosure, or short sale at four. The other declines that history regardless of age. Investment files follow the seven-and-four-year path.
Portfolio size caps exposure. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower owning more than 15 financed properties is not eligible.
State overlays apply. Texas primary residences are homestead properties and cap at 80% combined, so the tiers above that figure never apply there. New Mexico and Ohio scale the cap with the credit profile.
HELOC or DSCR Cash-Out on a Rental?
An investment HELOC is reviewed on your personal credit and debt-to-income. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio compares rent to the full housing payment: principal, interest, taxes, insurance, and any association dues.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Leverage | 70% CLTV | Around 75% on standard rentals |
| Size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
| Underwriting | Personal credit and DTI | Rent against payment |
| Title | Individual or revocable trust | LLC possible, subject to lender program eligibility |
Clearing a coverage ratio is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
For structures that fit larger or entity-held portfolios, the complete DSCR loans guide covers the full picture. Stronger coverage ratios can improve pricing and leverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
Why Advertised and Approved Amounts Differ
The advertised ceiling is the best case, and several things can pull an approved amount below it.
- The lender’s valuation comes in below the number you had in mind.
- Your first mortgage balance eats most of the room. The CFPB’s HELOC booklet shows the basic method: take a percentage of appraised value, then subtract what you owe. It uses 75 percent only as an illustration, not a market cap.
- The full credit limit counts toward CLTV even if you plan to draw less.
- Debt-to-income, qualified on the interest-only payment at the maximum draw, turns out tighter than the equity does.
That last one can catch investors who own several properties. Equity can be plentiful while the debt-to-income math sets the real limit.
Risks of Borrowing Near the Cap
Pricing on these lines floats, and the repayment period brings a larger payment once the interest-only draw ends. The same CFPB brochure notes that a lender may reduce a line if home value falls significantly.
Borrowing at the ceiling leaves little cushion if values soften. A primary-home line also puts your home at risk, and some line agreements restrict renting the property out. Keep that in mind before using a primary-home line for rental activity.
A fair read: these lines suit short-term capital such as a down payment or a rehab. They suit permanent leverage on a rental less well, because of floating pricing and the repayment step-up.
What to Prepare If You Want the Top Tier
A short checklist, in the order it matters:
1. Confirm the occupancy class for the property you are borrowing against.
2. Pull your credit and confirm you meet the tier you want. The report cannot be more than 90 days old at closing, and no rescores are allowed.
3. Calculate your CLTV with the full line limit, not just the amount you plan to draw.
4. Add up your debt obligations across all financed properties and test them against the 50% and 45% limits.
5. Check title. The property must be in your name or a revocable living trust.
6. Confirm the property type is on the eligible list and is not listed for sale.
If you miss the top tier, the options are a smaller line, a lower tier at the same lender, a vesting change, or a DSCR cash-out on a rental. Lendmire’s piece Top HELOC Providers at the Highest Loan-to-Value Lenders Allow covers the lender side of that search.
Key Terms Defined
Combined loan-to-value (CLTV): all liens on the property, including the new line, divided by the property’s value.
Draw period: the stretch when you can borrow against the line and typically pay interest only.
Repayment period: the stretch after the draw ends, when principal and interest are both due.
Debt-to-income ratio (DTI): your monthly debt obligations divided by your monthly income.
DSCR: the debt service coverage ratio, which compares a rental’s income to its housing payment.
Vesting: how title to the property is held, such as an individual or a revocable living trust.
Frequently Asked Questions
Can I get a 90% HELOC on a rental property?
No. On an investment property, the ceiling in Lendmire’s wholesale network is 70% combined loan-to-value. The 90% tier exists only on primary residences and second homes, and only at a 720 or better credit profile on lines up to $500,000.
Does a higher credit score raise my investment-property ceiling?
It does not. A 700 score is the minimum for an investment line, and a higher score keeps the file eligible without lifting the 70% cap. Credit tiers do move the ceiling on primary residences and second homes.
Can an LLC hold the property for a HELOC?
Not on these programs. Title must sit with the individual borrower or a revocable living trust. If the property is already in an LLC, the choices are a vesting change or a DSCR cash-out, subject to lender program eligibility.
Why is my approved line smaller than the advertised ceiling?
Three limits apply at once: the CLTV room after your first mortgage, the program’s dollar cap, and your debt-to-income capacity. The smallest controls. A valuation that comes in lower than expected also shrinks the room.
Does a HELOC require a full appraisal?
Not always. Lines at or below $500,000 ordinarily use an automated valuation, though a higher CLTV may require a secondary valuation. Every line above $500,000 requires a full appraisal, and any borrower may request one.
