The Quick Read: Occupancy sets your maximum combined LTV first and credit sets it second. Across Lendmire’s wholesale network, an investment property tops out at 70% combined LTV. A primary residence or second home can reach 90% only at a 720 credit profile or better, subject to lender guidelines and full file review.
- Combined LTV (CLTV) adds every loan on the property, including the new line’s full limit, and divides by the property’s value.
- The formula is value × ceiling − existing liens. The result is your room, in dollars.
- Your final line is the lowest of three tests: the CLTV room, the program’s dollar cap, and your debt-to-income ratio at the maximum draw.
- On an investment property, a 700 score and a 720 score reach the same 70% ceiling.
- Title matters. An LLC cannot hold title on these lines, which is the sharpest difference from a DSCR loan.
What Combined LTV Actually Measures
CLTV is the total of all loans secured by the property, divided by the property’s value. A regular LTV counts only the first mortgage. CLTV counts the first mortgage, any other recorded lien, and the new line you are asking for.
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.
The new line counts at its full credit limit, not at the balance you plan to draw. Money you size “for later” uses up CLTV room today.
A HELOC is a revolving line of credit. Because it sits on top of an existing mortgage, it works like a second mortgage. It can also stand alone in first-lien position if the property has no mortgage.
No single number applies to every lender. Each program sets its own ceiling based on occupancy, credit tier, property type, and its own risk limits. That is why a generic “80% to 85%” answer does not help an investor. NerdWallet reports that most HELOC lenders cap combined LTV at about 85%, and that figure describes owner-occupied homes across the broader market. On Lendmire’s network, an investment property tops out at 70%.
The 8-Step Checklist
Work through these steps in order. Each one includes what to gather before you call anyone.
Step 1: Establish current value
Value means today’s market value as the lender measures it. It does not mean your purchase price, and it does not mean a projected value after repairs.
Lines at or below $500,000 ordinarily run on an automated valuation, with no traditional appraisal. A higher CLTV may call for a second valuation. You can also request a full appraisal in any case. Every line above $500,000 requires one.
Gather: a recent valuation estimate, your purchase date, and notes on any major work done since.
Step 2: List every lien
Write down the first mortgage and every other recorded lien. That includes an existing second mortgage or an open equity line.
Gather: the current first-mortgage statement, the homeowner’s insurance declaration page, and your vesting deed.
Step 3: Count the full credit limit
The new line enters the math at its full limit. A $200,000 line with $150,000 drawn still counts as $200,000. Decide the size you want before you run the numbers.
Step 4: Pick the ceiling by occupancy and credit tier
Occupancy comes first. The table below shows the network ceilings by occupancy, as typical ranges subject to lender guidelines.
| Occupancy | Top CLTV | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% | 700 minimum | $500,000 |
| Second home | 90% at 720+ | 640 minimum | $500,000 |
| Primary residence | 90% at 720+ | 600 minimum | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
Primary residences step down with credit. On a primary residence, 90% applies only up to $500,000 and only at 720 or better. A 700 profile reaches 85% up to $500,000. A 640 profile reaches 80%, and a 600 profile reaches 60%. A primary-residence line above $500,000 caps at 75% CLTV and requires a full appraisal. The credit requirement for that larger line is 700 or better (720 on the longer-runway program described later).
On a second home, the ceiling is 90% at 720 or better, 85% at 680 and 700, 80% at 660, and 75% at 640.
On an investment line, a 680 score does not qualify at all.
Step 5: Compute the room
The formula is simple: maximum line = value × ceiling − existing liens.
Take a property worth 100 units, any currency. Liens total 40% of value, and the investment ceiling is 70%. That leaves 30% of value available. The brief version: 100 × 0.70 = 70, and 70 − 40 = 30.
Step 6: Apply the program’s dollar limits
The CLTV room is only the first test. The program also has flat dollar limits: a $25,000 minimum line and a $500,000 maximum on investment property. The lowest of the tests wins. A property with large equity still gets stopped at the dollar cap.
Step 7: Run DTI at the maximum draw
Debt-to-income (DTI) compares your monthly debts to your income. The maximum is 50%. It drops to 45% for profiles between 600 and 679, and a ratio above 45% requires a 680 minimum. The 45% tier therefore matters for primary residences and second homes, since investment lines start at 700.
The lender tests DTI on the interest-only payment calculated at the maximum draw. A big line weighs on DTI even if you plan to draw little.
Gather: recent pay documents or other income proof, a debt list, and your credit report details.
Step 8: Check title and eligibility
The property must be held by you personally or by your 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 first, or a DSCR cash-out refinance instead.
Eligible property types are single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, and agricultural zoning are not eligible.
How the Lowest-of-Three Test Works
The final line is the smallest result among three tests. Each test can be the one that stops you.
| Test | What it asks | What you check |
|---|---|---|
| CLTV room | Does value × ceiling − liens leave room? | Value, all liens |
| Dollar cap | Is the line within program limits? | $25,000 minimum, $500,000 investment cap |
| DTI at max draw | Can your income absorb the payment? | 50% maximum, 45% for 600-679 |
A low-mortgage owner with a big income can still hit the dollar cap. A high-equity owner with heavy debts can still fail the DTI test. Run all three before you decide the line is worth chasing.
Worked Examples
These examples use a property valued at 100 units so the percentages stay visible. They are modeled assumptions, not market data.
Standard case on an investment property. Liens at 40, ceiling at 70. The room is 30.
Multiple liens. A first mortgage at 45 plus an existing second at 10 puts liens at 55. At a 70% ceiling, the room is 15. Forgetting the older second lien would show 25 instead, an overestimate of 10 units, or two-thirds more than the real room.
Negative result. Liens at 75, ceiling at 70. The formula gives −5. Treat anything at or below zero as no room. The path then runs through paying down liens, waiting for value to rise, or a different structure.
Low valuation. You expect a 100 value, liens are 60, and the ceiling is 70. Expected room is 10. The valuation comes back at 90. Now 90 × 0.70 = 63, and 63 − 60 = 3. A small drop in value shrank the room from 10 to 3.
Illustrative CLTV Table
This table shows how each ceiling changes the room when liens equal 50% of a property’s value. The ceilings come from the network ranges above, and each one is tied to where it applies.
| Ceiling | Total debt allowed | Room | Where it applies |
|---|---|---|---|
| 60% | 60 | 10 | Primary residence, 600 tier |
| 70% | 70 | 20 | Investment property, 700+ |
| 75% | 75 | 25 | Primary residence line above $500,000 |
| 80% | 80 | 30 | Primary residence, 640 tier |
| 90% | 90 | 40 | Primary or second home, 720+, up to $500,000 |
The numbers show why occupancy matters so much. Moving from a 70% ceiling to a 90% ceiling doubles the room, from 20 to 40. But 90% simply does not exist for a rental on this network.
Structures and Variations
Lendmire brokers HELOCs through select wholesale partners, and the file is underwritten by the lender. Two programs sit behind the numbers above. The higher-leverage program offers a 3-year interest-only draw followed by a 17-year repayment. The longer-runway program offers a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year structure only.
At least 75% of the line is drawn at closing. This is a standalone line, in first or second lien position. Combined exposure per borrower caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower is limited to three lines.
Two exclusions matter for investors. A borrower who owns more than 15 financed properties is not eligible. And a line above $500,000 is available on primary residences only.
Where the Rule Breaks
LLC title. For experienced investors who hold rentals in entities, this is a hard stop. The fix is a vesting change into your name or a revocable trust, or a DSCR cash-out refinance, which is built for entity-held rentals subject to program terms.
Credit below 700 on a rental. No lower tier exists. A 690 score on an investment property does not move to a reduced ceiling. It does not qualify under this program.
State rules. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Ohio and New Mexico apply a CLTV cap that depends on the credit profile. A Texas primary residence caps at 80% combined LTV, so the higher matrix tiers never apply there.
Falling values. The CFPB’s HELOC booklet shows the credit limit being set as a percentage of appraised value minus the mortgage balance. It also notes that lenders can reduce a line if the home’s value declines. Your room can shrink after closing, not just before it.
Fewer lenders. NerdWallet notes that investment-property HELOCs come from fewer lenders and carry strict qualification requirements, and some lenders may require multiple appraisals. The network ceiling of 70% fits that picture.
Common Mistakes That Distort Your Number
- Counting only the drawn balance. The full limit counts.
- Using purchase price as value. The lender’s valuation sets the number.
- Forgetting an older second lien. Every recorded lien belongs on the list.
- Assuming a higher score raises a rental ceiling. On an investment property, 700 and 720 land at the same 70%.
- Assuming rent qualifies you. A HELOC is reviewed on personal credit, DTI, and equity. A DSCR loan, by contrast, qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- Borrowing the full amount of a purchase. A 70% ceiling cannot fund a whole purchase on the investment collateral alone, and a line sized that way would leave no equity in the property.
HELOC or DSCR Cash-Out?
A HELOC can win when you hold title personally, have a score of 700 or better, and carry a low first mortgage you would rather keep. It leaves the existing first lien intact.
A DSCR cash-out refinance replaces the first mortgage. It reaches about 75% LTV on a standard rental and 70% on short-term-rental collateral, with about six months of seasoning as the common expectation. It suits LLC-held properties and investors whose personal DTI is already stretched. Lendmire’s complete DSCR loans guide covers those mechanics. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
If Your Number Comes Out Low
Start by finding which test stopped you. The fix depends on the answer.
- CLTV room too small: Paying down a lien raises room dollar for dollar. A fresh valuation after improvements may support a higher appraised value, depending on comps and underwriter review.
- Dollar cap too low: A line above $500,000 is not available on rentals. A DSCR cash-out may fit a larger need.
- DTI too high: Size the line smaller, since DTI is tested at the maximum draw. Paying off a debt also helps.
- Title in an LLC: Look at a vesting change or the DSCR route.
- Credit under 700 on a rental: Rebuilding the score is the only path on this program. A DSCR file with a lower credit floor may fit sooner. A 620 floor exists in parts of the network, and most DSCR programs want around 660.
Key Terms Defined
CLTV (combined loan-to-value): The total of all loans on the property, including the new line’s full limit, divided by value.
LTV (loan-to-value): The first mortgage balance divided by value, with no other liens counted.
Lien: A recorded legal claim on the property that secures a loan.
Full limit versus drawn balance: The full limit is the most you may borrow. The drawn balance is what you have actually used. CLTV counts the full limit.
DTI (debt-to-income): Your monthly debt payments divided by your monthly income.
Vesting: How title is held, such as in your name, a revocable trust, or an LLC.
Frequently Asked Questions
What is the maximum combined LTV on an investment property HELOC?
On Lendmire’s network, an investment property tops out at 70% combined LTV, subject to lender guidelines and full file review. The minimum credit score is 700, and the line size runs from $25,000 to $500,000. Market-wide figures near 80% to 85% describe owner-occupied homes, not rentals. A 720 score buys no more leverage than a 700 score on a rental.
Does CLTV count what I draw or the whole line?
It counts the whole line, not just the balance you carry. At least 75% of the line is drawn at closing on these programs, so the gap between limit and balance is small at the start.
Can my LLC hold title on a HELOC?
No. Title must sit with you personally or in an inter vivos revocable living trust. A property deeded to an LLC needs a vesting change first. A DSCR cash-out refinance is the usual alternative for entity-held rentals, subject to program terms.
Why would a valuation change my line after I applied?
The room depends on value × ceiling − liens, so a lower valuation shrinks the result sharply. When liens are already close to the ceiling, even a modest drop in value can remove more than half the room. The CFPB booklet also notes that lenders can reduce a line if the home’s value declines later.
Do HELOC rules vary by state?
Yes, in a few places. Ohio and New Mexico apply a CLTV cap tied to the credit profile. A listed or recently listed property is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. Confirm state rules before relying on any estimate.
