How Much Can You Borrow on an Investment Property HELOC for Landlords Comparing a Bank?

The Quick Read: It depends on your equity, your credit, and the lender, but on the network Lendmire works with, an investment-property line tops out at 70% combined loan-to-value (CLTV) and a $500,000 maximum line, with the cap measured against property value minus what you still owe on the first mortgage. Banks set their own limits, and many cap rentals lower than owner-occupied homes.

• The limit comes from CLTV and equity, not from rent coverage.
• Qualifying for an investment line requires a 700 minimum credit score.
• The maximum line is $500,000, and the minimum is $25,000 (Michigan’s is $10,000).
• The deed must sit in your personal name or a revocable living trust, not an LLC.
• If the property is in an LLC or you need rent-based underwriting, a DSCR cash-out refinance is the usual alternative.

The answer is mostly arithmetic, plus a handful of rules that decide whether the arithmetic ever gets applied. This article covers both.

How Is the Maximum Line Calculated?

The maximum line equals the property value times the maximum CLTV, minus the balance on your existing mortgage. The CFPB’s HELOC booklet describes this method: a percentage of the appraised value, less what you owe. Its older edition uses 75 percent as an illustration only, so treat it as a method, not a limit.

On the wholesale network Lendmire brokers through, an investment-property line reaches 70% CLTV. Credit of 720 or better and credit of 700 both reach that same ceiling, so a higher score buys eligibility, not extra leverage.

Run the formula on three situations, expressed as percentages so you can plug in your own numbers.

Ample equity. Picture a rental with a first mortgage under 40% of its value. At a 70% cap, the remaining room is roughly 30% of value, subject to the $500,000 maximum line. The line size is limited by equity and by that cap, whichever is lower.

Thin equity. Say the first mortgage is already near 65% of value. A 70% cap leaves only about 5% of value to borrow against. On a modest property, that can fall below the $25,000 minimum line, which means no line exists at all.

New purchase. An investor who bought with 20% to 25% down has a first mortgage at 75% to 80% of the price. That is already above a 70% CLTV cap, so there is no borrowable equity until the balance falls or the value rises. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

The calculator on this page gives an illustrative estimate of these relationships. It is not a quote.

What Does a Bank Do Differently on a Rental?

A bank usually lends less on a rental than on your own home, and fewer banks offer the product at all. NerdWallet’s explainer on investment-property HELOCs says borrowers face fewer lenders and can’t borrow as much as against a primary home. It also notes that strict requirements apply and that more than one appraisal may be needed to confirm value.

The reasoning is risk. A landlord who gets squeezed tends to protect the home they live in first. So lenders cap rentals lower, ask for more reserves, and sometimes decline the product entirely.

Here is how the three common paths compare on the factors that matter.

A broker doesn’t change the product’s rules. A bank gives you one answer from one set of overlays. A broker that shops a wholesale network can match the scenario to the program whose terms fit, and the best program for your situation depends on property type, credit profile, leverage need, and documentation.

What Do the Network’s Lenders Look For?

The lenders behind these lines look at credit, debt-to-income, valuation, property type, and title. The specifics below come from the network’s investment-line guidelines and are subject to lender guidelines and full file review.

Credit. Investment lines require at least a 700 score. The score model is single-bureau and keyed to the primary wage earner, and the report can be no more than 90 days old at closing. No rescores.

Debt-to-income. The maximum is 50%. Qualification runs on the interest-only payment calculated on the maximum draw, not on what you actually borrow on day one. That detail trips up borrowers who plan to draw modestly but get tested on the full line.

Valuation. Because investment lines cap at $500,000, they sit in the automated-valuation lane and commonly close with no traditional appraisal. A higher CLTV can trigger a secondary valuation, and a borrower may request a full appraisal in any case. That request matters after a rehab, because an automated model may not capture renovation value. A full appraisal is the way to put the improvements in front of the lender.

Property type. Single-family, two-to-four units, PUDs, townhomes, and condos, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.

Draw structure. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Under the program terms, pricing floats through both periods and does not convert to fixed. After closing, the minimum subsequent draw is $1,000, except in Texas at $4,000. That last figure is stated by one wholesale program; the other does not state subsequent-draw minimums.

The CFPB’s plain-language HELOC explainer describes the draw-then-repay pattern in general terms, and the same page warns that falling behind can cost you the home securing the loan.

Why Title Decides Eligibility Before the Math Does

An LLC cannot hold title on these lines. Fee simple or leasehold must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts are out.

That is the sharpest structural difference from a DSCR loan. If your rental sits in an LLC, a HELOC calculation is moot until the vesting problem is solved. Your options are a vesting change, or a DSCR cash-out refinance, which can often accommodate an entity borrower, subject to lender program eligibility. Changing vesting on a property with an existing first mortgage can touch that loan’s terms, so read the first-mortgage documents and talk to an attorney before re-deeding anything.

Other structural limits worth knowing before you apply:

• A borrower is limited to three lines, with combined exposure capped at $2,000,000 on one wholesale program and $750,000 on the other.
• A borrower owning more than 15 financed properties is not eligible.
• Lines can sit in first or second lien position.
• A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.

Availability is also narrower than Lendmire’s 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.

What About the Figures Banks Quote Elsewhere?

You will see other numbers around the market. Market surveys and lender pages report investment-property equity lines at widely different leverage levels, and some banks cap a rental well below owner-occupied limits. Those figures describe the broader market, not this network. On this network, an investment line is 70% CLTV with a $500,000 maximum, full stop.

The reason to keep the comparison straight is that primary-residence lines work differently. On a primary home, the network’s ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. A line above $500,000 is primary-residence only, requires a 700 or better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal. None of that carries over to a rental. When a bank officer quotes a primary-home number, ask which occupancy it applies to.

Should You Use Your Own Home’s Equity for the Rental?

Some landlords tap the primary residence instead, because primary lines allow higher leverage. It works mechanically, but it moves the risk onto the home you live in. The CFPB states that missed payments can put the home at risk. It also notes that some plans prohibit renting out the home and that a HELOC generally must be paid off in full on sale.

A rental-collateral line keeps the exposure on the investment. A primary-home line spreads it across your household. Neither is wrong. The decision depends on how much cushion your own income gives you if a vacancy runs long.

Pre-Application Checklist for a Bank Conversation

Before you ask a bank for a number, assemble the following. Missing items are the quiet friction on these files.

1. Vesting proof. The deed showing your name or trust, and a clear statement of whether any entity holds title.

2. First-mortgage statement. The current balance sets the equity math.

3. Insurance declarations. Current landlord coverage on the property.

4. Income documents. Lenders on rentals sometimes ask for more than a paystub. Some request a profit-and-loss statement on the rental portfolio.

5. Property list. Count of financed properties, since exposure caps and the 15-property limit apply.

6. Valuation plan. If you rehabbed recently, decide in advance whether to request a full appraisal.

Then ask three direct questions. Does this bank offer a line on a non-owner-occupied property at all? What combined leverage cap applies to rentals specifically? Is the line tested on the full limit or on what I draw?

When the Bank Says No

If the bank doesn’t lend on rentals, a broker can place the file with a wholesale lender that does. If leverage is the issue, waiting for principal paydown or value growth is the only fix. A bigger down payment on a past purchase doesn’t create new borrowing room; it simply lowers the first mortgage. If title is the issue, see the LLC section above.

If your debt-to-income fails, the line may be the wrong product. A HELOC tests you. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Self-employed investors, borrowers with many financed properties, and LLC holders often fit that structure better. Rent comes out of the calculation as rent divided by the full monthly obligation, and clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, and management sit outside it. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.

Equity: The property’s value minus what you owe on it.

Draw period: The stretch when you can borrow from the line, paying interest only on investment lines.

Repayment period: The stretch after the draw ends, when principal and interest amortize. On investment lines it runs 25 years.

Automated valuation: A model-based value estimate used instead of a full appraisal on lines at or below $500,000.

Vesting: How title is held, whether in your name, a revocable trust, or an entity.

Risks Worth Pricing In

These lines carry variable pricing that floats for the life of the line. Interest-only payments during the draw mean the balance doesn’t shrink on its own. When the repayment period starts, the payment steps up as principal begins to amortize. A lender can also reduce or freeze a line if value drops, a risk the CFPB booklet flags alongside the variable-rate structure.
