How Much Can You Borrow on an Investment Property HELOC for an Equity-Rich Landlord?

The Quick Read: On a rental property, the most a landlord can borrow through Lendmire’s wholesale network is a $500,000 line at up to 70% combined loan-to-value (CLTV), and extra equity does not raise either cap. The line size is the property value times 70%, minus every lien already on the property, and the result is then limited by the $500,000 ceiling and the borrower’s debt-to-income ratio.

• The minimum credit profile is 700, and the minimum line is $25,000.
• A score of 700 and a score of 720 both reach the same 70%.
• Debt-to-income (DTI) tops out at 50%, and it often binds before equity does.
• Title must sit in your name or a revocable living trust. An LLC cannot hold it.
• Equity beyond the HELOC cap is usually reached through a DSCR cash-out refinance, which tests rent instead of personal income.

Everything below is subject to lender guidelines and full file review. It is not a commitment to lend.

What Is the Formula for the Maximum Line?

The formula is value times the CLTV cap, minus all existing liens. CLTV counts the first mortgage plus the new line’s limit, divided by the property’s value. On an investment property, the cap is 70%.

The CFPB’s HELOC definition describes equity as value minus what you owe on the mortgage. Its older HELOC booklet shows the same method: take a percentage of the home’s value, then subtract the mortgage balance. The booklet uses 75% purely as an illustration. Investment-property lines in the network use 70%.

Run three scenarios, each expressed as percentages of value.

• Lightly leveraged rental. The first mortgage is about 30% of value. The 70% cap leaves roughly 40 points of value for the line. If the property is valued high enough that 40% of its value exceeds $500,000, the dollar ceiling binds first. On a lower value, the percentage cap still sizes the line.
• Typical leveraged rental. The first mortgage is about 55% of value. The cap leaves roughly 15 points. The line is sized by equity, and the dollar ceiling is far away.
• Paid-off rental. There is no first mortgage. The cap allows 70% of value, again limited to $500,000 once 70% of value passes that figure.

The takeaway: the percentage cap binds on most mid-priced rentals with a mortgage, and the dollar cap binds on high-value, low-debt properties. Being equity-rich pushes you toward the dollar cap. It never lifts it.

What Limits the Line Besides Equity?

Five tests apply, and failing any one shrinks or kills the line. The table shows each one.

Credit works differently here than on a purchase loan. Scores of 700 and 720 both reach 70% on a rental, so a higher score buys eligibility, not leverage. The 90% CLTV ceiling that appears in some advertising applies only to primary residences and second homes, and only at a 720-or-better profile. It does not apply to rentals.

DTI is the quiet constraint. This line is qualified on the borrower, meaning credit, income, and debt load, and not on the rent. A landlord with several mortgaged rentals carries a lot of existing debt, and the 50% DTI maximum can cap the line before the 70% CLTV does. The qualifying payment is calculated as interest-only on the maximum draw, which is a conservative test.

Why Doesn’t More Equity Raise the Cap?

The cap is a program rule, not an equity calculation. The network’s investment line tops out at $500,000 regardless of how much equity the property holds. Lines above $500,000 are limited to primary residences, where the maximum reaches $750,000 at up to 75% CLTV with a full appraisal.

This surprises landlords who read general guidance. NerdWallet’s overview of investment-property HELOCs notes that the lender pool is smaller and that borrowing is lower than against a primary home. That matches what brokers see across wholesale channels: fewer lenders, tighter leverage, and hard dollar ceilings on rentals.

One more contrast helps. Some lenders will go higher on a primary-residence line. The network’s investment figure stays at 70% CLTV, and that is the number to plan around.

How Do Title and Entity Structure Change Eligibility?

Title must be held by you personally or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this line.

This is the sharpest structural difference from a DSCR loan, which commonly closes in an LLC, subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead. Moving title into your own name can have insurance and liability consequences, so settle that question before the application, not during it.

Two more eligibility points matter for portfolio owners:

• Each line is secured by one property. Equity in one rental cannot support a line on another.
• A borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.

Property type also matters. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.

How Does the Line Work After Closing?

An investment line runs a 5-year interest-only draw period, then a 25-year fully amortizing repayment period. At least 75% of the line is drawn at closing. Pricing floats for the whole life of the line and never converts to fixed. The CFPB notes that if you fall behind on a HELOC, you could lose the property securing it.

The 75% draw-at-closing requirement matters for planning. A landlord who wants a standby line, with little drawn, does not fit this structure. It works better for someone with a defined use for most of the funds, such as a down payment on the next rental or a renovation budget.

Valuation is usually automated. Because an investment line caps at $500,000, and full appraisals are required only above that size, these lines ordinarily run an automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation, and the borrower can always request a full appraisal. If the automated value comes in low, the line shrinks with it, because the formula starts with value.

Documentation is the other friction point. Expect to supply a credit report no more than 90 days old at closing, evidence of the borrower’s income and debts, a mortgage statement for every existing lien, and proof of title in the correct name. The file stalls when a lien is missing from the application or when vesting does not match the title report.

When Does a DSCR Cash-Out Beat the HELOC?

A DSCR cash-out refinance fits better when the equity exceeds what the HELOC cap allows, when the first mortgage is not worth keeping, or when personal DTI is the constraint. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, so a landlord with heavy portfolio debt is not tested on personal DTI the same way.

The two products solve different problems:

The decision rule is simple. If the existing first mortgage is worth keeping and the equity needed fits under $500,000 and 70% CLTV, the HELOC leaves that mortgage untouched. If the first mortgage needs replacing, or the amount needed is larger, the DSCR cash-out is the cleaner path. On a cash-out, about 6 months of seasoning is the common expectation, and reserves commonly run around 6 months of PITIA, varying by lender, leverage, and loan size.

Coverage is where files get tripped up. A DSCR compares rent to PITIA only, and many select programs start at 1.00. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Lendmire’s complete DSCR loans guide lays out how those programs work. For a head-to-head view, see Lendmire’s piece on choosing between an investment property HELOC and a DSCR cash-out for an equity-rich landlord.

How Should a Multi-Property Landlord Size a Line?

Size it against one property at a time, then check the combined DTI. Because each line is secured by a single property, a portfolio does not pool equity. A landlord with five rentals evaluates five separate formulas, and the line on any one property is capped by that property’s value, its liens, and the $500,000 ceiling.

The three-line limit and the 15-financed-property limit shape the strategy. A landlord who wants to tap equity across many properties will hit those limits, and a DSCR cash-out on the largest-equity property may do more work than several small lines.

Draw strategy matters because the payment floats. Stage spending where you can, and stress the interest-only payment at a higher variable figure before you commit. Keep draws and receipts organized by use, since tax treatment can depend on how the funds are used and how the property is held. Borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
