How Much Can You Borrow on an Investment Property HELOC on an Inherited Rental?

The Quick Read: The line is the gap between a 70% combined loan-to-value ceiling and whatever liens already sit on the house, capped at a $500,000 maximum line on Lendmire’s network, and only after the heir holds recorded title.

• On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), subject to lender guidelines.
• The maximum line on an investment property is $500,000, with a 700 minimum credit score.
• A 720 score and a 700 score reach the same 70% ceiling, so a higher score buys eligibility, not more leverage.
• A paid-off inherited house leaves the full ceiling open. An inherited mortgage uses part of it.
• No lien can be placed until the deed is recorded in the heir’s name.

Heirs often look at an inherited rental and see a large equity number. The usable line can be smaller than that number suggests. Three limits stack on top of each other: the CLTV ceiling, the liens already on the property, and the program’s maximum line. This article walks through each one, then covers the title problems that can stop an inherited-property line before the math starts.

What Sets the Maximum Line?

The line equals the smaller of two numbers: the room left under the CLTV ceiling, or the program’s maximum line size. CLTV adds every lien on the property and divides by current value. No federal regulator sets a CLTV cap for investment-property lines. The limit is lender and investor policy.

NerdWallet confirms that a HELOC on an investment property is possible, but that not every lender offers one and qualification is strict. Investment lines run tighter than lines on an owner-occupied home.

On the wholesale network Lendmire brokers through, the investment-property figures are:

• Ceiling: 70% CLTV.
• Maximum line: $500,000.
• Minimum credit score: 700.
• Debt-to-income (DTI): 50% maximum, qualified on the interest-only payment calculated on the maximum draw.

All of this is subject to lender guidelines and full file review. It is not a commitment to lend.

The formula is simple. Take 70% of the property’s value. Subtract the balance of every existing lien. What remains is the room. Then compare it to the $500,000 line cap.

Worked Example: Paid-Off Rental vs. Inherited Mortgage

Run it as percentages of value, not dollars.

Scenario one: free and clear. An heir inherits a rental with no mortgage. Existing liens are 0% of value. Room under the ceiling is the full 70% of value, though the line still stops at $500,000. On a modest house, the ceiling binds first. On a high-value house, the line cap binds first.

Scenario two: inherited mortgage. Say the decedent’s first mortgage equals 45% of current value. Room under the 70% ceiling is 25% of value. The line cannot exceed that, even if the heir feels the house holds far more equity.

A line can sit in first or second lien position on this network. In scenario two, it would be a second lien behind the inherited mortgage.

On an investment line, valuation is usually automated. Because an investment line caps at $500,000 and full appraisals begin only above that, these lines commonly close without a traditional appraisal. A borrower can still request one.

Can an Heir Borrow Before Title Transfers?

Usually not. A HELOC is a lien, and the borrower needs legal authority to pledge the property. While probate is open, the estate generally holds title, not the heir.

Closed probate is not the same as a recorded deed. The deed must be recorded in the heir’s name before any lender can move forward. Property passing through a transfer-on-death designation or a revocable trust can reach the heir without probate, but the vesting still has to show the borrower.

An executor may be able to act for the estate, and some lenders make estate-level loans. Those are different products from an heir’s personal line. This article covers the heir’s line.

Co-heirs

When several heirs own the property together, every owner generally has to sign. One tenant-in-common heir cannot borrow against the whole house over the others’ objections. Lendmire’s piece Bank Statement Cash-Out Refinance Rules on an Inherited House covers that co-owner problem in more detail. Most lenders will not lend against a fractional interest, so plan on a buyout or a unanimous signature.

Title held by an LLC

This is the sharpest structural limit. On this network, the borrower must hold title individually or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on a HELOC. If a decedent’s LLC still owns the house, the heir needs a vesting change first. Or the better route may be a DSCR cash-out refinance, which can work with an entity borrower, subject to lender program eligibility.

What About the Decedent’s Existing Mortgage?

The lien survives the death, and it counts toward CLTV. Get a payoff statement from the servicer before doing any math.

Federal law limits a servicer’s ability to call a mortgage due when a home passes to certain family members. The CFPB’s mortgage-servicing amendments define a confirmed successor in interest, who is entitled to servicing communications like payoff statements. A Yahoo Finance explainer notes that servicers accept documents such as a death certificate, a will, or a probate order. It also stresses that none of this forgives the debt.

So the practical rule is: protection from a due-on-sale call is not a lien payoff. Every dollar owed still reduces your room.

Who Underwrites the Line: You or the Rent?

You. A HELOC on this network is reviewed on personal credit, DTI, and equity. The rent on the inherited rental is not underwritten the way it is on a DSCR loan. NerdWallet lists a DTI range of 40% to 50% for these lines in the broader market and says 50% may be acceptable based on projected rental income. Treatment of rent varies by lender.

Here are the network’s credit and DTI points:

• Minimum score for an investment line: 700.
• DTI maximum: 50%. Because every investment line already requires at least a 700 score, the 680 minimum that applies to ratios above 45% on other lines is never the binding limit here.
• Credit report no more than 90 days old at closing. No rescores.
• A bankruptcy needs 4 years of seasoning. Foreclosure seasons at 7 years, and a deed-in-lieu, pre-foreclosure, or short sale at 4 years, on investment files.
• A borrower with more than 15 financed properties is not eligible.

Typical documents: the first-mortgage statement (if any), insurance declaration, the vesting deed, and a lease if the lender asks for one.

Property and Structure Limits That Catch Heirs

Eligible property types include single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. An inherited farmhouse or a rural property on agricultural zoning will not fit.

The structure on an investment line is fixed:

• A 5-year interest-only draw period, then a 25-year fully amortizing repayment.
• At least 75% of the line is drawn at closing.
• Pricing floats across both the draw and repayment periods and never converts to fixed.
• Minimum subsequent draw: generally $1,000 after closing.
• Line size starts at $25,000.

That 75% draw at closing matters. A HELOC here is not a standby line you leave untouched, so size it to the actual use, not to the maximum.

Availability is also narrower than the DSCR footprint. These lines are offered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.

Does the Tax Step-Up Raise What You Can Borrow?

No. Lenders use their own valuation. The tax step-up is a separate matter. IRS Publication 551 says inherited-property basis is generally the date-of-death value. That sets depreciation and future gain. It does not set the CLTV denominator. Tax treatment varies; consult a qualified professional.

When a DSCR Cash-Out Fits Better

An investment HELOC tests the borrower. A DSCR loan tests the property. DSCR compares rent to PITIA, and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. An heir with solid rent but heavy personal debt, or with title sitting in an LLC, may fit DSCR better.

The leverage picture is different too. Most DSCR cash-out files on the network top out around 75% LTV, with about 6 months of seasoning as the common expectation. Coverage of 1.00 is where select programs start, not a universal standard. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Credit floors, reserves, and property eligibility still apply, and clearing the ratio is not the same as positive cash flow, since repairs, vacancy, and management sit outside the calculation. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Key Terms Defined

CLTV (combined loan-to-value): All liens on the property added together, divided by current value.

Lien position: Your line’s place in line for repayment; first lien is paid before a second.

Draw period: The stretch when you can borrow, paying interest only.

Successor in interest: A person who takes ownership of a home from a borrower, often by inheritance.

DSCR: Monthly rent divided by the full housing payment, including principal, interest, taxes, and insurance.
