The Quick Read: It is a home equity line sized so that all liens on the home, your first mortgage plus the new line, reach the lender’s combined loan-to-value ceiling. On Lendmire’s network that ceiling is 70% CLTV on an investment property. On a primary residence it reaches 90% CLTV, but only with a credit profile of 720 or better. No federal rule sets that number. Each lender or investor chooses it, and every figure here is subject to lender guidelines and full file review.
- Investment lines run from $25,000 to $500,000 at the 70% ceiling.
- On a primary residence, the ceiling reaches 90% CLTV only with a 720+ credit profile, and only for lines up to $500,000. That higher tier does not apply to investment property, where the ceiling stays at 70%.
- The full line limit counts toward CLTV, whether or not you draw it.
- Investment lines are underwritten on the borrower’s credit and income, not on rent.
- A rental held in an LLC cannot take this line, so a vesting change or a DSCR cash-out is the usual alternative.
What Does Maximum LTV Mean on a HELOC?
Maximum LTV on a HELOC is the highest share of the home’s value that all liens combined may reach after the line is added. Lenders call it combined loan-to-value, or CLTV. The line is the gap between that ceiling and what you already owe.
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.
Plain LTV looks at one loan against value. CLTV looks at every loan secured by the home. If a first mortgage already uses half the value and the ceiling is 70%, the new line can use at most the remaining 20% of value. The formula is simple: (existing balance + new line) ÷ value = CLTV.
A HELOC is an open-end line you can borrow against repeatedly. The federal consumer-finance regulator explains that you can generally draw up to your limit during the draw period, which can last 10 years. The FTC adds that these lines typically carry a variable cost of borrowing, and you pay only on the amount you actually use.
Key Terms Defined
LTV (loan-to-value): One loan balance divided by the home’s appraised or estimated value.
CLTV (combined loan-to-value): All loans secured by the home, including the new line limit, divided by value.
Draw period: The stretch of years when you can borrow from the line, usually paying interest only.
Second lien: A loan that sits behind the first mortgage and is paid in addition to it.
DTI (debt-to-income): Your monthly debts divided by your monthly income.
Vesting: The name or entity that holds legal title to the property.
How the Maximum Line Is Calculated
The maximum line is the lower of two results: the equity room under the CLTV ceiling and the program’s dollar cap. Brokers run the same sequence on every file. The steps below match how the network sizes a line.
1. Establish value. Lines at or below $500,000 ordinarily run on an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation, and a borrower may ask for a full appraisal in any case.
2. Apply the ceiling. Multiply value by the maximum CLTV for the occupancy type and credit tier.
3. Subtract existing liens. Take out the first mortgage and any other liens. The entire new line limit counts, even if you never draw it.
4. Compare to the dollar cap and floor. Investment lines run $25,000 to $500,000. A free-and-clear rental still stops at the cap. A thin slice of room can fall below the floor, and then no line is available.
5. Review the borrower. Credit, income, and DTI are checked, because the line is underwritten on the person, not the property.
The percentage is the lender’s choice.
Here is how that plays out when expressed as shares of value, using the investment-property ceiling of 70% CLTV and the primary-residence ceiling of 90% CLTV, which applies only with a 720+ credit profile and a line of up to $500,000.
| Scenario | First mortgage | Room under ceiling |
|---|---|---|
| Investment, 70% CLTV | 40% of value | 30% of value |
| Investment, 70% CLTV | 60% of value | 10% of value, may miss $25,000 floor |
| Investment, 70% CLTV | 70% of value or more | — |
| Primary residence, 90% CLTV with 720+ credit only | 60% of value | 30% of value, capped at $500,000 |
The break-even on the investment side is easy to see. A $500,000 first mortgage leaves no room until the home’s value passes roughly $714,300, because $500,000 is 70% of that value.
Maximum CLTV by Occupancy and Credit
Ceilings on this network are tiered by occupancy first and credit second. An investment line tops out at 70% CLTV with no higher tier. Primary residences reach 90% CLTV, and only at a 720-or-better credit profile.
| Occupancy and credit | Max CLTV | Max line |
|---|---|---|
| Investment, 700+ | 70% | $500,000 |
| Primary, 720+ | 90% | $500,000 |
| Primary, 700+ (720 on the longer-runway program), larger line | 75% | $750,000 |
| Primary, 700+ | 85% | $500,000 |
| Primary, 640+ | 80% | $500,000 |
| Primary, 620+ | 70% | $400,000 |
| Primary, 600+ | 60% | $400,000 |
The credit floor differs by occupancy. A primary residence can go as low as 600, and an investment property starts at 700.
Credit above the threshold does not buy investment leverage. A 700 score and a 720 score reach the same 70% CLTV on a rental. Extra score adds eligibility, not room.
The 720 Tradeoff on a Primary Residence
A primary residence at 720 carries a choice, not one answer. With a 720+ credit profile, you can take 90% CLTV up to $500,000, or a larger line up to $750,000 at a reduced 75% CLTV. A line above $500,000 is primary-residence only, requires a full appraisal, and needs a credit profile of 700 or better (720 on the longer-runway program, the wholesale option built around a 5-year draw). Lendmire places these lines with two select wholesale programs whose terms differ, so each figure applies only within its own program.
Why Approval Can Land Below the Ceiling
The ceiling is a maximum, not a promise. Several tests can shrink the line before CLTV even matters.
Credit tier. A lower score moves the borrower to a lower CLTV row and a lower dollar cap. The report comes from a single-bureau score keyed to the primary wage earner, and it can be no more than 90 days old at closing.
DTI. The maximum is 50%. It drops to 45% for credit profiles from 600 to 679, and a ratio above 45% requires a 680 minimum. The qualifying payment is calculated on the interest-only payment at the maximum draw, so a bigger line raises the test it must pass.
Valuation. An automated estimate can come in below the number an owner expects. A lower value shrinks the room directly. A borrower may request a full appraisal when the estimate looks light.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. For a foreclosure, deed-in-lieu, pre-foreclosure, or short sale, one wholesale program seasons a foreclosure at 7 years and the others at 4. The other program declines that history entirely, no matter how old it is. Investment files follow the 7-and-4-year path.
Exposure. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.
Title, Property Type, and the LLC Wall
The line must be held by an individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
That is the sharpest structural difference from a DSCR loan. A rental already deeded to an LLC needs a vesting change before a HELOC is possible, or it needs a DSCR cash-out instead. A vesting change brings its own title and insurance steps, so it deserves a conversation with the title company before it is treated as a quick fix.
Eligible properties include single-family homes, 2-4 units (with a 640 minimum on the longer-runway program), PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not eligible. A property listed for sale, or listed within the past 60 days, is ineligible in several states.
Availability is also narrower than the DSCR footprint. These lines are offered in 16 full-service states, while DSCR investor loans reach 41 markets, including Washington, D.C.
Borrowing at the Ceiling
A line sized at the ceiling leaves the least cushion if anything moves. Three mechanics matter.
Most of the line is drawn up front. At least 75% of the line is drawn at closing on both programs. A maximum line is therefore mostly a funded second payment from day one, not an unused reserve.
The cost floats. Pricing floats through both the draw period and the repayment period and never converts to fixed. Draw structures differ by occupancy. Primary residences and second homes can run a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment only. When the draw ends, the line begins fully amortizing, and the payment steps up.
The line can shrink. The CFPB notes that lenders can bar additional draws if the home’s value falls significantly. A line sized at the 70% combined loan-to-value ceiling for an investment property has little room for that kind of decline.
On a rental, the second payment must also be absorbed by cash flow. Because the HELOC is qualified on the borrower, the lender does not test whether rent covers it.
A short self-check helps before using the whole ceiling:
- Does the rental still cover its first mortgage and the new payment if a unit sits vacant for a stretch?
- Is the purpose of the money a project that adds income, or only spending?
- Would the repayment-period payment fit if the draw period ended tomorrow?
Can You Go Higher? What Market Surveys Say
Some lenders in the broader market go above these ceilings. Experian reports that some lenders allow very high CLTV for strong profiles on owner-occupied homes. Forbes Advisor says lenders typically want borrowers to keep 15% to 20% equity, which means a CLTV below 80% to 85%. Those are market-wide statistics, and they largely describe owner-occupied homes. On Lendmire’s network the figures are the ones above: 70% CLTV on an investment property, and up to 90% CLTV on a primary residence only with a 720+ credit profile.
If a HELOC ceiling is too low for the goal, a DSCR cash-out refinance is the other tool investors compare. Across the network it typically tops out around 75% LTV on standard rentals and around 70% LTV on short-term-rental collateral. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and about 6 months of seasoning is the common expectation. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and it replaces the first mortgage rather than sitting behind it. Because the test is rental income rather than the borrower’s personal profile, a property held in an LLC can be considered, subject to program guidelines. A HELOC cannot be placed on a property titled in an LLC.
The tradeoff is real. A HELOC keeps the existing first mortgage in place, which matters when that loan has terms worth protecting. A cash-out gives up that loan and resets the balance. The complete DSCR loans guide covers the cash-out side.
The DSCR route may fit better for an investor with many mortgages or hard-to-document income, because rent, not personal DTI, is the test. An investor with one rental, a low first mortgage, and strong personal income may find the HELOC fits better.
Common Misreadings of the Maximum
The maximum is a fixed number. It is not. It is set by the lender and varies by occupancy and credit.
The maximum equals total equity. The ceiling applies to total liens, so usable equity is smaller than total equity.
Only drawn dollars count. The whole line limit counts toward CLTV.
Higher credit means more leverage on a rental. On the investment line it adds eligibility only.
Approval locks the line in. Lines can be frozen or reduced if value drops.
How to Find Your Maximum
Work the number in this order and you will see your real ceiling before applying.
1. Pin down occupancy. Decide whether the property is a primary residence, second home, or investment property, since that sets the ceiling tier.
2. Estimate value. Use a realistic figure, since an automated valuation can land below an owner’s guess.
3. Add up every lien. Include the first mortgage and any other liens.
4. Run the formula. Value × ceiling − existing liens gives the equity room.
5. Check the dollar cap. Compare the result to the program cap and the $25,000 floor.
6. Confirm title. Individual or revocable trust only.
7. Gather credit and income documents. The score, DTI, and housing history all feed the line size.
Frequently Asked Questions
What is the maximum LTV for a HELOC?
No single maximum exists, because each lender sets its own. On Lendmire’s network the ceiling is 70% CLTV on an investment property. A primary residence can reach up to 90% CLTV only with a 720-or-better credit profile, subject to lender guidelines.
Does the HELOC maximum include the amount I haven’t drawn?
Yes. The full line limit counts toward combined loan-to-value, whether or not you borrow it. A larger line therefore uses more of your ceiling the day it is set up.
Can a rental in an LLC get a HELOC at the maximum LTV?
No, not on this network. Title must be held by an individual or a revocable living trust. An LLC-held rental needs a vesting change or a DSCR cash-out refinance instead.
Why was my line smaller than the ceiling suggested?
The line is the lower of the equity room and the dollar cap, and a low valuation, DTI above the limit, or a thin slice of room under the $25,000 floor can reduce or block it. The ceiling is a limit, not an entitlement.
Is a higher credit score worth more on a rental line?
It does not add leverage on an investment line, since 700 and 720 reach the same 70% CLTV, which is the ceiling for investment properties. A better score can help on a primary residence or second home, where a 720+ credit profile unlocks the 90% tier.
