The Quick Read: Maximum combined loan-to-value on an investment-property equity line is 70% across the select wholesale lenders Lendmire works with, while primary homes and second homes can reach higher tiers when credit is strong; total equity never sets the limit, because every lien counts against that cap.
- On an investment property, the ceiling is 70% combined loan-to-value, with a 700 minimum credit score and a line of up to $500,000.
- On a primary residence, the ceiling reaches 90% only at a 720-or-better credit profile, and on a second home the same 90% ceiling also needs 720.
- The lender qualifies you as a borrower on credit, income, and debt. It does not test the rental’s income against its payment.
- Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on these lines.
- A DSCR cash-out refinance is the usual alternative when the property sits in an LLC or the equity line is too small.
What Is a HELOC, and Why Does the Cap Matter More Than Your Equity?
A HELOC, or home equity line of credit, is a revolving credit line secured by a property. You borrow against it, repay, and borrow again within a set period. Your equity is the property’s value minus what you owe. The lender’s cap decides how much of that equity you can actually use.
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.
That cap is expressed as combined loan-to-value, or CLTV. It adds your first mortgage balance and the new line’s full limit, then divides by the property’s value. Because it counts every loan on the property, it is stricter than a single-loan ratio.
Here is the part that surprises new investors. A property with plenty of equity can still produce a small line. Equity of 50% of value sounds large. Under a 70% CLTV cap, a first mortgage at 50% of value leaves room for a line of only 20% of value.
What Are the Core HELOC Requirements?
A lender checks six things: combined leverage, credit, debt load, occupancy and title, property type, and valuation. Each one can end the file by itself. Strong equity does not rescue a weak credit score, and a good score does not raise a cap that the occupancy tier has already set.
| Requirement | What it controls |
|---|---|
| Combined LTV | How large the line can be |
| Credit score | Whether the file is eligible, and which tier |
| Debt-to-income | Whether your total debts fit |
| Occupancy and title | Which tier applies, and who may hold title |
| Property type | Whether the collateral is eligible at all |
| Valuation | How the value is established |
Across our wholesale network, the overall credit floor on these lines is 600, and it applies to primary residences only, where the lowest tier is 60% CLTV. Second homes floor at 640, and investment properties floor at 700. The lender uses a single-bureau score tied to the primary wage earner, and the report must be no more than 90 days old at closing.
Debt-to-income, or DTI, is your monthly debts divided by your monthly income. The maximum is 50%. A profile between 600 and 679 is held to 45%, and anything above 45% needs at least a 680 score. The lender also reviews your file on the interest-only payment calculated on the maximum draw, not on the amount you plan to use.
How Is the Maximum Line Calculated, Step by Step?
The maximum line equals the property’s value times the CLTV cap, minus every existing lien. Four steps get you there, and each one is simple arithmetic.
1. Establish value. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. A higher CLTV may require a secondary valuation, and you can request a full appraisal in any case.
2. Apply the cap. Multiply that value by the cap for your occupancy and credit tier.
3. Subtract existing liens. Count the first mortgage balance and the full limit of any other line already on the property, not just the drawn amount.
4. Check the line-size limits. Lines run from $25,000 to $750,000, but only a primary residence can exceed $500,000, and it then needs a full appraisal and caps at 75% CLTV. An investment property tops out at $500,000.
The step most people skip is the third one. An undrawn line from a prior lender still reduces your room, because lenders count the limit, not the balance. Pull the payoff and the limit for every lien before you estimate anything.
How Much Do Credit and Occupancy Move the Ceiling?
Occupancy sets the ceiling, and credit decides which tier you reach beneath it. Investment property is the tightest tier at 70%. Primary residences and second homes have more room, but their top tier is reserved for the strongest credit.
| Occupancy | Credit | Max CLTV | Max line |
|---|---|---|---|
| Primary residence | 720+ | 90% | $500,000 |
| Primary residence (larger line) | 700+ (720 on the longer-runway program) | 75% | $750,000 |
| Primary residence | 700+ | 85% | $500,000 |
| Primary residence | 640+ | 80% | $500,000 |
| Second home | 720+ | 90% | $500,000 |
| Second home | 640+ | 75% | $500,000 |
| Investment property | 700+ | 70% | $500,000 |
Notice what the investment row does not show. A 720 score earns the same 70% as a 700 score, so a better score confirms eligibility there but does not raise the cap.
Lendmire is a mortgage broker, not the lender. It places these lines with two wholesale programs. One is a higher-leverage program, with combined exposure of up to $2,000,000 across three lines. The other is a longer-runway program, with combined exposure of up to $750,000. Where their terms differ, each figure here applies only inside its own program.
Lines above $500,000 exist only on primary residences. They need a credit profile of 700 or better (720 on the longer-runway program), cap at 75% CLTV, and require a full appraisal.
What Does a Low Appraisal Do to the Line?
A lower value shrinks the line twice: the cap applies to a smaller number, and your first mortgage becomes a larger share of it. The examples below use percentages of the value you expected, with a 70% cap, which is the investment-property tier.
| Case | First mortgage | Max line |
|---|---|---|
| Value holds | 50% of expected value | 20% of expected value |
| Value comes in 10% low | 50% of expected value | about 13% of expected value |
| Heavy existing balance | 65% of expected value | 5% of expected value |
The middle row is the one that hurts. A 10% valuation miss cuts the line by about a third in this example. Size your plan on the low-appraisal row, not the optimistic one, if the money has a specific job to do.
What Draw Structures Exist?
Primary residences and second homes can choose between two structures. The first is a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The second is a 5-year draw followed by a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment structure only.
Both programs require that at least 75% of the line be drawn at closing. That detail changes the decision. You are not opening a large, mostly idle reserve. You are taking most of the money on day one and carrying a floating-price balance on it.
Pricing floats through the draw period and the repayment period and never converts to a fixed structure. After closing, the longer-runway program sets a $1,000 minimum for each later draw.
The practical read: this product suits a short, defined use of cash. It is a poor fit for a permanent funding source.
Where Does the General Rule Break?
Title held in an LLC. Only you personally or a revocable living trust can hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. If the rental is already deeded to an LLC, you need a vesting change or a different product. This is the sharpest difference from a DSCR loan.
Property type. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable ones) are eligible. The 2-4 unit category carries a 640 minimum on the longer-runway program. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by occupancy. Investment files follow a path of 7 years after a foreclosure and 4 years after a deed-in-lieu, pre-foreclosure, or short sale.
Portfolio size. You are limited to three lines at once, and an investor with more than 15 financed properties is not eligible.
Listed properties and geography. A property listed for sale, or listed within the past 60 days, is ineligible in several states. Lendmire places these lines only in its 16 full-service states, which is narrower than its 41-market DSCR footprint that includes Washington, D.C.
Scarce lenders. Few lenders write equity lines on rentals at all, a point investors raise often on BiggerPockets. A broker that shops several wholesale lenders matters here, because one lender’s exclusion is rarely every lender’s exclusion.
Can You Borrow Against Your Home to Buy the Next Rental?
Often, yes, and that is why many investors take the line on their primary residence instead of the rental. A primary residence carries higher CLTV tiers than an investment property, and the cash can fund a down payment. Tax treatment varies; consult a qualified professional.
The tradeoff is that your home becomes collateral for the investment. If the rental underperforms, the lender still looks to the house.
What Are the Risks of Borrowing Near the Cap?
Borrowing near the cap leaves no cushion against a falling value, a rising payment, or a repayment period that arrives sooner than expected. Each of the three can hurt on its own, and they can arrive together.
The federal consumer HELOC booklet explains the basic method lenders use: set the limit as a percentage of value, then subtract the mortgage balance. Its 75% figure is only an illustration, and the federal government sets no maximum. The ceiling is each lender’s own policy.
The government’s HELOC overview also warns that you could lose the property if you cannot repay. For an investor, that risk shows up in three ways.
- Floating cost. The balance reprices through draw and repayment, so a payment that works today may not work later.
- Repayment reset. The interest-only draw ends and the loan begins amortizing, which raises the monthly obligation.
- Value drops. A lender may reduce or freeze a line if the property value falls.
A safer plan sets the line below the maximum and treats the cap as a limit, not a target.
Does a DSCR Cash-Out Refinance Fit Better?
It often does when the rental sits in an LLC, when the line would be too small, or when you want the property’s rent to do the qualifying. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A HELOC qualifies you as a borrower.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
| Factor | Investment HELOC | DSCR cash-out |
|---|---|---|
| Reviewed on | Your credit, income, DTI | Rent vs. payment |
| Max leverage | 70% CLTV | About 75% LTV |
| Title | You or revocable trust | LLC allowed* |
| Lien type | Revolving, floating | Fixed-spine term loan |
| Seasoning | None stated | About 6 months |
*LLC titling is subject to lender program eligibility.
The 75% figure applies to cash-out on standard rentals. Short-term-rental collateral is held to 70% on cash-out. A DSCR loan sets the combined leverage at the new first lien, because it replaces the existing mortgage.
Coverage runs differently. A 1.00 ratio is where many 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 1.00 does not mean positive cash flow. The ratio compares rent to PITIA (principal, interest, taxes, insurance, and association dues) only, so repairs, vacancy, management, and utilities sit outside it.
Credit also differs. A 620 floor exists in parts of the network and most programs want around 660, with 700+ unlocking the strongest leverage tiers. Loans run up to $3,000,000 on standard programs (smaller balances available through select lenders), and the spine is a 30-year fixed structure. Extended 40-year terms, interest-only periods, and ARMs are available through select lenders.
The complete DSCR loans guide walks through those requirements in detail.
How Do You Know Your Number?
Work from the cap downward, not from your equity upward. The order below keeps the file clean.
1. Confirm occupancy and who holds title.
2. Pull your credit profile and identify your tier.
3. Gather the first mortgage payoff and every other line’s full limit.
4. Estimate value, then rerun the math at a lower value.
5. Calculate DTI on the maximum draw’s interest-only payment.
6. Choose a line size below the result.
If title, property type, or portfolio size fails, no amount of equity changes the answer. That is when the second option in the table above deserves a look.
Key Terms Defined
Lien: A legal claim against a property that secures a loan. A first mortgage and a HELOC are both liens.
Draw period: The stretch of time when you may borrow against the line, usually with interest-only payments.
Repayment period: The stretch after the draw period when the balance amortizes and you can no longer borrow.
DTI (debt-to-income): Your total monthly debts divided by your monthly income.
Vesting: The way title is held, such as in your own name or in a revocable living trust.
Automated valuation: A computer-generated property value used in place of a traditional appraisal.
Seasoning: The waiting period a lender wants after you buy or refinance before another cash-out.
DSCR (debt service coverage ratio): A property’s rent divided by its full monthly payment of principal, interest, taxes, insurance, and dues.
Frequently Asked Questions
Can I get an equity line on a rental owned by my LLC?
Not directly. On these lines, title must be held by you individually or in a revocable living trust, and LLCs cannot hold it. A property already deeded to an LLC needs a vesting change first. The other path is a DSCR cash-out refinance, which can accommodate an LLC, subject to program terms.
Does the whole line count toward CLTV, or only what I draw?
The whole limit counts. Lenders add the first mortgage balance and the full line limit before they divide by value. An undrawn line on the same property still reduces what a new lender will allow. Pull the limits, not just the balances.
Will a higher credit score raise the cap on an investment property?
Not within the investment tier. A 700 score and a 720 score both sit at 70% CLTV there, and 700 is the minimum to apply. A higher score matters more on primary residences, where the top tier reaches 90% at 720 or better.
What happens if the appraisal comes in low?
The line shrinks, and by more than the percentage the value missed. The cap applies to a smaller value while your first mortgage stays the same. Lines at or below $500,000 ordinarily use an automated valuation, and you can request a full appraisal in any case.
Can I use a home equity line for the down payment on my next rental?
Many investors do, usually with a line on their primary residence. The lender reviews your file on your credit and debt, and the line must clear that residence’s own cap. Because most of the line is drawn at closing, plan the payment on the full draw.
