How Much Can You Borrow on an Investment Property HELOC for Rental Owners Funding Repairs?

The Quick Read: It depends on your equity, but the formula is simple: on an investment property, your line is 70% of the property’s value minus every lien already on it, up to a $500,000 maximum, subject to lender guidelines and credit approval.

• The 70% figure is a combined loan-to-value cap. It counts your first mortgage plus the new line.
• Credit must be at least 700 on an investment line. Scores of 700 and 720 both reach the same 70% ceiling, so a higher score does not buy more leverage.
• Debt-to-income can run up to 50%, tested on the interest-only payment on the full line.
• Title must sit in your name or a revocable living trust. An LLC cannot hold title on this product.
• At least 75% of the line is drawn at closing, so size it to your repair budget rather than your maximum.

How Is the Limit Calculated on a Rental?

Take the property’s value and multiply it by the 70% cap. Subtract your first mortgage and any other liens. What remains is your borrowing room, before dollar limits and your own credit and income checks.

Combined loan-to-value (CLTV) is the total of all loans against the property divided by its value. The new line counts at its full limit, whether you draw it or not.

Run the numbers on a modeled example. Assume a $400,000 rental with a $240,000 first mortgage. That mortgage already sits at 60% of value. A 70% cap leaves 10% of value, or $40,000, before any other test applies.

The first mortgage balance drives everything. This table shows how much room is left at different balances:

The 65% row catches people off guard. On a $400,000 rental, 5% is $20,000. The minimum line is $25,000, so there is nothing to borrow.

At the other extreme, a high-value rental with little debt hits the $500,000 line maximum before it hits the 70% cap. Whichever limit is lower wins.

Why Do Rentals Get Less Than a Primary Home?

Lenders see more default risk on rentals. NerdWallet’s explainer on investment-property HELOCs notes that this leads to fewer lenders offering the product, stricter requirements, and sometimes multiple appraisals.

Across our wholesale network, the gap is built into the tiers. On a primary residence or second home, the ceiling reaches 90% CLTV, and only with a 720-or-better credit profile. On an investment property, it stops at 70% CLTV with no tier above it.

That gap is why some owners look at their own home first. Hold that thought, because it carries a real tradeoff, covered below.

What Else Can Shrink Your Line?

The CLTV formula gives you the ceiling. These checks can pull the number down:

• Credit. Investment lines require at least 700. Below that, there is no lower tier.
• Debt-to-income. The limit is 50%, and the lender tests it on the interest-only payment on the maximum draw. A big line can use up your DTI even if you never draw it all.
• Valuation. Lines at or below $500,000 usually run on an automated valuation with no traditional appraisal. An automated value may not reflect work you just finished, so you can ask for a full appraisal if you want one.
• Ownership. The borrower must hold title individually or in a revocable living trust. A rental already deeded to an LLC needs a vesting change, or a different product.
• Property type. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not.
• Portfolio size. A borrower can hold up to three lines. Owners with more than 15 financed properties are not eligible.

Availability is also narrower than the rest of the business. Lendmire arranges DSCR investor loans across 41 markets, including Washington, D.C. The equity line described here is limited to its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. Lendmire is a broker, not the lender, and none of this is a commitment to lend.

How Do You Size the Line to a Repair Budget?

Start with the scope of work, not the maximum. Get contractor bids, add a contingency cushion for overruns, and treat that total as your target. Then work backward to the line.

One rule changes the usual HELOC logic. At least 75% of the line is drawn at closing. You can’t open a large line and let it sit untouched until the roof bill arrives. Most of it is borrowed on day one.

Here is how that plays out:

• Match the line to the upfront need. If your project needs most of its money early, a line sized near the budget fits well.
• Staged projects fit less neatly. If you turn units one at a time over many months, a big opening draw means carrying a balance you haven’t spent.
• Later draws are allowed. After closing, you can take the remaining draws, each with a minimum of $1,000 (Texas is $4,000).
• Keep the floor in mind. The smallest line is $25,000. A small repair does not fit this product.

The line also leaves your first mortgage in place. If your existing loan is worth keeping, that is a real advantage over refinancing the whole thing.

How Do Draws and Repayment Work?

An investment line runs a 5-year draw period followed by a 25-year repayment period. During the draw period, payments are interest-only. In repayment, the balance amortizes fully.

Pricing floats across both periods and never converts to fixed. The CFPB’s HELOC booklet says home equity lines typically carry variable rates, so payments can rise. Your lease doesn’t rise with them. You carry that risk.

The line also isn’t guaranteed to stay open. The CFPB’s HELOC overview notes a lender may restrict further credit if the home’s value drops significantly. Don’t plan a project around draws you might not get later.

Stress-test the plan before you sign. Ask what happens if repairs run long, the unit sits vacant an extra stretch, or the payment moves up. If the property can’t carry the line during those gaps, size down.

HELOC, DSCR Cash-Out, or a Line on Your Home?

Each option solves a different problem. This table compares them:

A DSCR cash-out refinance replaces your first mortgage. It runs around 75% LTV on standard rentals across most of the network, and about 6 months of seasoning is the common expectation. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. LLC-owned rentals can be eligible, depending on program guidelines.

Coverage works like this. A 1.00 ratio is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Reserves commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and association dues), though they vary by lender, leverage, and loan size.

One caution: clearing 1.00 does not mean positive cash flow. DSCR compares rent to the monthly payment only. Repairs, vacancy, management, and utilities sit outside it.

Choose the line when you have solid equity, a first mortgage worth keeping, a 700-plus score, and title in your own name. Choose cash-out when the first mortgage has eaten the room, the LLC holds title, or the repair is large. A line on your own home may price better, but you put your residence at risk. The complete DSCR loans guide covers the rent-qualified side in depth.
