The Quick Read: Usually the answer is the lower of two numbers: the equity room under the lender’s combined loan-to-value cap, and the amount your income and monthly debts can support. Equity sets the ceiling, and income decides whether you reach it.
- Equity room equals property value times the maximum combined loan-to-value (CLTV), minus every loan already secured by the property.
- Income enters as a debt-to-income (DTI) ratio. Across Lendmire’s wholesale network, 50% is the maximum, and 45% applies to credit scores from 600 to 679.
- The ceiling depends on occupancy: up to 90% CLTV on a primary residence or second home with a 720-or-better credit profile, and 70% CLTV on an investment property.
- A line on an investment property runs $25,000 to $500,000, and the network requires a 700 minimum credit score for those lines.
- A line limit is not the same as the amount you should draw, because unused credit can still count against your DTI.
The Two-Gate Rule: Equity First, Income Second
Every home equity line passes through two gates. The first is equity, which is a property question. The second is income and debt, which is a you question. The lender sizes the line at whichever gate is tighter.
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.
Most borrowers only think about the first gate. They look at their home value and their mortgage balance and assume the difference is theirs. It is not. Lenders hold back a cushion, so a share of the value always stays untouched.
Lenders also run the second gate on the payment, not on the balance. That detail trips up many investors who hold several mortgages. A property can have plenty of equity and still produce a smaller line than expected, because the borrower’s monthly obligations leave little room.
Lendmire arranges these lines through select wholesale lenders as a broker, never as the lender. Every figure below is a range or guideline, subject to lender guidelines and a full file review.
Key Terms Defined
Equity is the property’s current market value minus what you owe on it.
Lien is a loan secured by the property. Your first mortgage is a lien, and so is the HELOC itself.
CLTV (combined loan-to-value) is every lien on the property added together and divided by its value.
DTI (debt-to-income) is your total monthly debt payments divided by your gross monthly income.
Draw period is the stretch when you can borrow from the line and payments are interest-only.
Repayment period is the stretch after the draw ends, when the balance amortizes and payments include principal.
Step One: How Much Equity Can You Use?
The formula is simple. Take the appraised or automated value, multiply it by the maximum CLTV, and subtract every lien already on the property. What is left is your equity room. Experian’s HELOC guide lays out the same logic, and Yahoo Finance notes that every loan on the property counts if you have more than one.
Only current market value counts. BiggerPockets makes the point that neither your purchase price nor a projected post-renovation value goes into the calculation.
Here is how the caps differ. Lendmire’s network sets its ceilings by occupancy, and the highest tier is reserved for stronger credit:
| Occupancy | Top CLTV in the network | Credit pairing | Max line |
|---|---|---|---|
| Primary residence | 90% | 720+ | $500,000 |
| Primary residence | 75% | 700+ (720 on the longer-runway program) | $750,000 |
| Second home | 90% | 720+ | $500,000 |
| Investment property | 70% | 700+ | $500,000 |
The 90% figure exists only at a 720-or-better credit profile. Lower credit tiers step down from there. On a primary residence, a 660 score reaches 85% CLTV, a 640 reaches 80%, and a 620 reaches 70%. The minimum score on a primary residence is 600, on a second home it is 640, and on an investment property it is 700.
Credit does not buy extra leverage once you hit the top tier. On an investment property, a 720 score gets the same 70% CLTV ceiling as a 700.
Sizing the Room With Percentages
Treat value as 100 units. Suppose you own a rental and the first mortgage equals 50% of value. At the investment-property ceiling of 70% CLTV, the most you can add is 20% of value, before the $500,000 line cap. Suppose the first mortgage is already 65% of value. Only 5% of value remains. If the first mortgage sits at 70% or above, equity room is zero.
The same house as a primary residence at 90% CLTV with a 720 score would leave far more room. That is why occupancy matters more than almost any other input.
Step Two: Where Income Actually Enters
Income does not multiply your line. It acts as a limit on payment. The lender adds your existing monthly debts to the new line’s payment, divides by gross monthly income, and checks the result against its DTI ceiling.
The network’s maximum DTI is 50%. It drops to 45% for credit profiles from 600 to 679, and anything above 45% requires a 680 score or better. Exact terms depend on lender and investor guidelines, credit profile, reserves, and property review.
There is no fixed minimum income in dollars. The requirement is expressed as a ratio. A borrower with modest income and almost no debt can clear it, and a borrower with high income and heavy obligations may not.
The Payment That Counts
This is the detail that surprises people. The network qualifies the borrower on the interest-only payment calculated on the maximum draw, not on the amount you plan to borrow. An unused line can still count against you.
Because at least 75% of the line is drawn at closing, a very large line carries a large payment from day one. Size the request with that in mind.
Documenting Income
Employed borrowers typically document income through pay records and tax filings. Self-employed borrowers can often qualify on documented income under the applicable program, subject to lender guidelines. On Lendmire’s bank-statement HELOC, that changes only how income is counted, using deposits instead of tax returns. The CLTV cap, credit floor, and DTI ceiling stay the same.
Rental income is a separate question. These lines are underwritten on you, not on the rent a property produces. Some lenders in the wider market count a portion of projected rent, but practices differ, so treat any rental-income credit as the exception.
Four Scenarios: Which Gate Binds?
These are modeled cases, expressed as percentages so the logic stays visible. Each one assumes a borrower with a 720 score unless noted.
| Scenario | Equity room | Income check | Binding gate |
|---|---|---|---|
| Rental, first mortgage at 50% of value | 20% of value | Existing DTI 25% | Equity |
| Rental, first mortgage at 65% of value | 5% of value | Existing DTI 25% | Equity |
| Primary home, first mortgage at 60% of value, 90% CLTV | 30% of value | Existing DTI 40%, line adds 12 points (52% total) | Income |
| Retiree, primary home, low debts | Ample room | Documented income covers a small payment | Equity cap or line cap |
In the third case, the equity is there, but the new payment pushes DTI from 40% to 52%. That is above the 50% maximum, so the line shrinks until the ratio fits.
In the first two cases, the property is the limiting factor. The borrower could easily carry the payment, but the 70% CLTV investment ceiling leaves little room. Paying down the first mortgage or waiting for value to rise are the main ways to create more room under that ceiling.
The retiree case works when documented income, whatever its source, supports the payment. The lender looks at what is documented, so organized records matter more than the income label.
If you have a spouse or co-borrower, their income and their debts both enter the ratio. A second income helps only if the second person’s obligations do not offset it.
Investment Property Lines: The Rules That Surprise People
An investment-property line has its own parameter set, and it is narrower than a primary-home line.
- Leverage: The ceiling is 70% CLTV on an investment property, in first or second lien position.
- Size: The line runs $25,000 to $500,000. Only primary residences can have a line above $500,000, up to the network’s $750,000 maximum.
- Structure: Investment lines run a 5-year interest-only draw followed by a 25-year repayment. Pricing floats across both periods and never converts to a fixed figure.
- Credit: Nothing exists below a 700 score on an investment property.
- Valuation: Lines at or below $500,000 ordinarily use automated valuation, though a higher CLTV may require a secondary valuation. Any line above $500,000 needs a full appraisal, and you can request one in any case.
- Exposure: A borrower can hold up to three lines. A borrower with more than 15 financed properties is not eligible.
- Derogatory history: A bankruptcy needs 4 years of seasoning. Investment files follow the 7-year seasoning path for foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale.
The network has two wholesale programs behind its primary-residence and second-home lines. This article calls them the higher-leverage program and the longer-runway program. They differ in draw structure, exposure caps, and some credit standards, and each figure applies only within its own terms. A line above $500,000 on a primary residence requires a credit profile of 700 or better (720 on the longer-runway program), caps at 75% CLTV, and requires a full appraisal.
Title Is the Sharpest Catch
Title must be held by an individual or a revocable living trust. An LLC, corporation, partnership, or land trust cannot hold title. For investors with rentals titled in an LLC, a HELOC means a vesting change first. A DSCR cash-out refinance may avoid that, subject to lender program eligibility. Some individual lenders in the wider market allow an LLC at lower leverage, but that varies by lender and is not part of this network.
The network also does not offer lines on manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, or agricultural zoning. A property listed for sale, or listed within the past 60 days, is ineligible in some states.
Lines Can Shrink
Approval is not permanent. The CFPB’s HELOC booklet points out that a lender may reduce your credit line if your home’s value drops. It also flags variable-rate exposure as a standard risk. Both matter for investors who plan to keep a large balance outstanding for years.
Four Myths That Skew the Math
Myth: you can borrow 85% of your equity. The 85% figure, where it applies, is a cap on total debt as a share of value, not a share of equity. The lender’s cap includes the first mortgage.
Myth: you can borrow all your equity. Lenders hold back a cushion. At a 70% investment-property ceiling, at least 30% of value always stays untouched.
Myth: a government rule sets the cap. Lenders set their own CLTV caps and DTI limits. The caps vary because each lender prices its own risk.
Myth: rental income qualifies me. The line is underwritten on your income and debts. The property’s rent is not the test, which is the major structural difference from a DSCR loan.
How Much Should You Borrow?
A larger line is not a better line. Because DTI is tested on the payment at the maximum draw, a bigger limit tightens your ratio for every future application. That is a real cost if you plan to buy another rental in the next year.
Think about use of funds before you decide on size. Common uses include rehab, down payments, and reserves. Improvements may support a higher appraised value, depending on comps and underwriter review, while a down payment on another property builds an asset that can carry its own financing.
Variable pricing makes a long draw period feel cheap, but the repayment period begins whether or not the project paid off. Typical primary-home HELOCs run a 10-year draw and a 20-year repayment, according to BiggerPockets. The network’s investment structure is 5 years of interest-only followed by 25 years of amortization, so the draw ends sooner.

When a DSCR Cash-Out Fits Better
A HELOC is sized by equity and personal DTI. A DSCR cash-out refinance is sized by the property’s rent against its payment. Investors with many mortgages and a high DTI often hit the debt-ratio limit first on a HELOC, even when equity is plentiful.
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. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
On leverage, a cash-out refinance on a standard rental tops out around 75% LTV across most of the network, and around 70% on short-term-rental collateral. That compares with a 70% CLTV ceiling on an investment-property HELOC. Cash-out files commonly expect about 6 months of seasoning, and credit floors and reserves vary by lender, leverage, and loan size.
Clearing 1.00 coverage is not the same as positive cash flow. DSCR compares rent to the full monthly payment of principal, interest, taxes, insurance, and any association dues. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
A DSCR cash-out also replaces the first mortgage instead of adding a second lien, which changes the leverage picture. Lendmire’s complete DSCR loans guide walks through how those files are structured.
Ways to Raise Your Limit
- Pay down the first mortgage. Every point of value you pay off becomes equity room under the cap.
- Pay off other debts. Lower monthly obligations free up DTI, which is the gate that binds for many borrowers.
- Lift your credit tier. Moving from 660 to 720 on a primary residence takes the ceiling from 85% to 90% CLTV. On an investment property, the cap does not move above 700.
- Ask for a full appraisal. On lines at or below $500,000, you can request one if you believe automated valuation understates the property.
- Request a smaller line. A smaller draw means a smaller payment and a smaller ratio, which can clear a DTI limit you would otherwise miss.
- Add a co-borrower with strong income and low debts. Their obligations count, so the net effect depends on the full picture.
Frequently Asked Questions
Is there a minimum income to get a HELOC?
There is no fixed dollar minimum in the network’s parameters. Income shows up as a ratio, with a 50% DTI maximum and a 45% limit for credit scores from 600 to 679. A lower earner with few debts can pass, and a higher earner with heavy debts may not.
Which counts more, my income or my equity?
Whichever is tighter sets the line. Equity sets the ceiling, and income decides whether you can reach it. On an investment property, the 70% CLTV ceiling usually binds first, while on a primary home at 90% CLTV, income often binds first.
Can I borrow 100% of my home’s value?
Not on this network. Market surveys report that some lenders allow up to 90% CLTV on certain lines, according to Experian. The network’s ceiling is 90% on a primary residence or second home with a 720-or-better profile, and 70% on an investment property.
Does a HELOC count my rental income?
Lendmire’s network does not underwrite the line on property rent. It tests you as the borrower, on your income, your debts, and the interest-only payment at the maximum draw. A DSCR cash-out refinance is the product that looks at the property’s rent.
Can the lender reduce my line after approval?
Yes, in some circumstances. The CFPB notes that lenders may reduce a credit line if your home’s value drops. Pricing also floats and never converts to a fixed figure, so planning for the draw and repayment periods matters.
