How Much Can You Borrow on an Investment Property HELOC When Heirs Will Not Sell?

The Quick Read: Usually you cannot borrow anything on the shared house, because a lender needs a lien on the whole property and every heir on title must sign, so the borrowable amount stays at zero until title is consolidated or everyone agrees. Once title is clean, a formula sets the amount. Across our wholesale network, an investment-property line is limited by value, existing debt, and a fixed dollar cap.

• Title comes first. A house with several heirs on the deed cannot carry the line until the owners agree or one person holds title.
• The formula: value times 70% CLTV (combined loan-to-value), minus every existing lien, capped at $500,000.
• Credit floor: 700, a hard floor with no tier beneath it. Scores of 700 and 720 both reach the same 70% ceiling, so a higher score adds no leverage.
• Real exits: all heirs sign, one heir buys out the rest, a line on a property you own alone, or a rent-qualified DSCR cash-out refinance.

Why One Heir Cannot Borrow Over the Others’ Objection

Inherited real estate often passes to heirs as tenants in common. Each heir owns an undivided fractional share, and no single heir can convey the whole property alone. A North Carolina law firm’s Q&A on co-heirs explains that each co-owner can convey only their own interest, and a deed to the full tract needs every owner’s signature. State rules differ, so treat that as an illustration.

A mortgage lien works the same way. A home equity line is secured by the property, and the lender wants that security on the entire house. You could try to pledge only your fractional share, but that leaves the lender holding a slice of a house with a hostile co-owner attached.

A line on a shared inherited house is also a title problem before it is a credit problem. Probate has to be finished and the deed recorded to the heirs. Until then, only the executor can act, and only for the estate. That is an estate-level loan, not a home equity line.

Some assets skip probate, such as a funded trust or a survivorship deed, subject to title review. Those cases still run into the same wall if several heirs hold title and one refuses to sign.

What “Will Not Sell” Does and Does Not Mean

A refusing heir cannot stop a sale forever. In states that have adopted the Uniform Partition of Heirs Property Act, the court must first order an appraisal. The other co-owners then get a chance to buy out the heir who wants out.

The American Bar Association’s legislative update reports that roughly two dozen states, plus the U.S. Virgin Islands and D.C., have enacted the Act. Its stated purpose is to keep heirs’ property in the family where possible and to ensure heirs receive fair market value when a sale cannot be avoided.

For you, the point is leverage in the negotiation. The heir who says no has less power than they think. Pricing the court route, with its appraisal and buyout steps, gives both sides a concrete alternative to weigh.

How Much Can You Borrow Once Title Is Clean?

Once one person holds title, or every heir signs, the maximum line comes from a short formula. Take the property value, multiply by 70%, then subtract the first-mortgage balance and any other liens. What remains is the most the line can be, before the $500,000 cap.

Here is how it looks in percentages, with no dollar figures needed.

The 70% ceiling binds first on lower-value rentals. On a high-value house with modest debt, the $500,000 dollar cap binds instead. The minimum line is $25,000, so a thin sliver of room may not produce a usable line at all.

Other terms on an investment line across our network:

• Credit: a 700 floor with no tier beneath it, and no extra leverage above that floor.
• Debt-to-income: 50% maximum, qualified on the borrower’s credit and income profile rather than the rent.
• Structure: a five-year draw period followed by a 25-year repayment period. At least 75% of the line is funded at closing, and the pricing floats. That makes it a poor fit for small, staged draws.
• Valuation: an investment line tops out at $500,000, so valuation is typically automated and commonly closes with no traditional appraisal, though you may request one.
• Title: an individual or a revocable living trust. An LLC cannot hold title on this product, so a property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
• Limits: up to three lines per borrower, and a borrower with more than 15 financed properties is not eligible.
• Availability: this line is offered in 16 states, a narrower footprint than the DSCR programs in 41 markets, including Washington, D.C.

NerdWallet reports that investment-property lines typically ask for a credit score around 720, a maximum LTV of 80% with many lenders sitting below 70%, and DTI between 40% and 50%. That is a market-wide picture. On our network, the investment ceiling is 70% CLTV with a 700 credit floor, and all figures stay subject to lender guidelines and full file review.

One more point matters. The full credit limit counts toward your leverage and debt ratios even if you draw nothing.

Key Terms Defined

Tenants in common: a form of co-ownership where each owner holds an undivided share and can deal only with that share.

CLTV (combined loan-to-value): all loans secured by the property, added together, divided by its value.

Partition action: a court case that divides a co-owned property or orders it sold when owners cannot agree.

DSCR (debt service coverage ratio): monthly rent divided by the full monthly obligation of principal, interest, taxes, insurance, and any HOA dues.

Lien: a lender’s legal claim on a property as security for the loan.

Who Has to Sign?

When one heir borrows and the others agree only to sign the lien documents, the non-borrowing owners sign an acknowledgment and the security instrument. Their income does not help the file unless they are also borrowers. A departing owner who must come off an existing mortgage needs a payoff, a refinance, or the lender’s formal release.

What Are Your Options When Heirs Refuse?

You have four practical routes. Each solves a different problem.

Buyout sizing. Say the first mortgage is 40% of value. Equity is the other 60%. An heir who owns half of the equity is owed 30% of value, so your CLTV after the payout lands at 70%, exactly at the investment ceiling. That is the best case.

Now consider three siblings who split the equity equally, where two of them buy out the third. Each sibling’s share is one third of the equity, so the payout is at most about a third of the property’s value, and less whenever a mortgage exists. With a first mortgage at 40% of value, equity is 60% and the departing sibling is owed 20% of value. CLTV after that payout is 60%, which fits under the ceiling. With a first mortgage at 55% of value, equity is 45% and the payout is 15%, which puts CLTV after the payout at 70%, right at the limit. Any more debt than that calls for a phased buyout or a different product.

Another property. If you own a different property outright, a line against it may work without any heir signing. The new line is underwritten on that property and your own profile.

When a DSCR Cash-Out Beats a HELOC

A DSCR cash-out refinance replaces the existing first mortgage with a new loan sized on the rental’s income. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ceiling on a standard rental is around 75% LTV on a cash-out, with about six months of seasoning as a common expectation. A 75% cash-out ceiling leaves more room than a 70% CLTV line when the buyout is large.

Coverage matters here. A 1.00 DSCR is where many select programs start, and a stronger ratio opens better pricing and leverage. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. For DSCR loans specifically, most programs want a credit score near 660, with a 620 floor in parts of the network and 700-plus unlocking the strongest tiers. That differs from the investment HELOC, which has a hard 700 floor.

Reserves vary by lender, leverage, loan size, and transaction type. Around six months of PITIA (principal, interest, taxes, insurance, and association dues) is common. Loans above $1,500,000 typically step up to about nine months.

Two cautions apply. A cash-out loan replaces the inherited mortgage, which matters if that loan is one you would rather keep. And clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation.

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. Subject to program terms, an LLC can hold title on a DSCR file. If the title sits in several names, every owner still has to sign.

What Protections Do Heirs Have on an Inherited Mortgage?

Heirs who inherit a house with a mortgage get some federal protection. The CFPB’s mortgage servicing rule treats a confirmed successor in interest like a borrower for servicing purposes, and its categories track section 341(d) of the Garn-St Germain Act. Those protections help keep the existing loan from being called due on a covered transfer.

They do not give any heir a new line of credit. Do not read them as permission to borrow against the shared house.

Heirs also generally are not personally liable for the decedent’s debts. Debts secured by the property still follow the property.

The Risks Worth Pricing In

An investment line carries real risks. The payment floats, and at least 75% is funded at closing, so you start with a large balance. A line secured by an inherited rental puts that rental on the table if you cannot repay.

Lenders view default risk as higher on investment properties than on a primary home, which is why the ceilings are lower. Investors in a BiggerPockets discussion on financing repairs for an inherited property describe a line on non-owner-occupied property as hard to get, and they float alternatives such as a cash-out refinance or borrowing against a primary home. That thread is anecdotal.

Property type also matters. The investment line covers single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. It does not cover manufactured homes, co-ops, condotels, log homes, or commercial, mixed-use, or agricultural zoning. DSCR loans in our network are likewise not offered on manufactured homes, log homes, or barndominiums.

Ask early whether an offer is a true revolving line, a fixed second, or a cash-out refinance, because labels such as investment property HELOC are used loosely. A paid-off inherited house may also be treated as cash-out rather than rate-and-term, and treatment varies.

Step-by-Step: The Order That Works

1. Confirm who is on title. Finish probate and record the deed, or confirm a trust or survivorship deed.

2. Decide the structure. Pick from all-heirs-sign, buyout, another property, or DSCR cash-out.

3. Size the payout. Convert the buyout to a percentage of value and check it against the 70% CLTV limit.

4. Check your profile. Credit of 700 or better and DTI under 50% for the line, or rent coverage for a DSCR loan.

5. Apply. Valuation is typically automated on an investment line.
