How Much Can You Borrow on an Investment Property HELOC to Fund a Flip or BRRRR Project?

The Quick Read: You can usually borrow up to 70% combined loan-to-value (CLTV) on an investment property, capped at a $500,000 line, minus every lien already on that property. The line is sized on the equity in the property that secures it, not on the flip or BRRRR project you plan to buy. The approved amount then has to cover purchase, rehab, and carry.

• Ceiling: 70% CLTV on an investment property, with a $500,000 maximum line.
• Credit: 700 is the hard minimum, and a 720 score reaches the same 70% CLTV, so credit above 700 buys eligibility rather than extra leverage.
• Formula: value × CLTV cap − existing liens = room.
• Draw: at least 75% of the line is drawn at closing.
• Title: an LLC cannot hold title on the collateral property.

Subject to lender guidelines and full file review, and not a commitment to lend. Lendmire brokers these lines through select wholesale partners in its 16 full-service states. Its DSCR investor programs cover 41 markets, including Washington, D.C.

How Is the Maximum Line Calculated?

Multiply the property’s value by the CLTV cap, subtract the first mortgage and any other liens, then apply the dollar cap. That result is the most a lender can offer. It is not a promise of what you will get.

Take an illustrative case. A rental valued at $400,000 with a 70% cap supports $280,000 of total debt. If a $150,000 first mortgage is already in place, the room is $130,000. These are modeled numbers, not market data.

Three things shrink the answer:

• Higher existing liens, including hard money or a prior second.
• A valuation that comes in below the owner’s estimate.
• The dollar cap, which sits at $500,000 on an investment line.

Lines of $25,000 or more are the usual entry point. The network floor is $25,000, with a lower floor in Michigan.

Why Is an Investment HELOC Smaller Than a Home HELOC?

Lenders treat rentals as riskier collateral, so the cap is lower. NerdWallet notes that investors face a smaller pool of lenders and can’t borrow as much as against a primary home, because lenders see higher default risk on rentals.

The same split shows up in our network. Occupancy sets the ceiling:

The investment tier has just two credit levels, 720 and 700. Both reach 70%. Credit above 700 buys eligibility, not extra leverage, and 700 is a hard floor.

In this network, the 70% ceiling already implies at least 30% equity.

What Does the Line Have to Cover on a Flip or BRRRR?

A flip or BRRRR budget has four parts: purchase, rehab, carry, and closing costs. The line can pay for any of them, but only up to the room the collateral gives you. Many projects need more than a single rental line supplies.

A common mix is a HELOC for the purchase or down payment and other money for the rest. Investors on BiggerPockets describe using private money first and a line for the overage.

Two program rules shape the carry:

• At least 75% of the line is drawn at closing. You pay interest on that draw whether the rehab needs it yet or not.
• Investment lines run a 5-year interest-only draw followed by a 25-year repayment. Pricing floats the whole way and never converts to fixed.

Borrower qualification uses a 50% maximum DTI, calculated on the interest-only payment at the maximum draw. A large line can therefore push DTI up before you spend a dollar.

Which Property Carries the Line?

The line sits on a property you already own, never on the flip or BRRRR deal you are buying. A HELOC does not borrow against the after-repair value of a project. The line makes you a cash buyer, with money secured by equity in another property.

That has two consequences:

1. The equity must already exist in your primary home, second home, or an existing rental.

2. The collateral property carries the risk. If a project stalls, your rental or home is what’s pledged.

Title matters too. Fee simple or leasehold title must be held by you individually or in an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

Eligible collateral includes single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.

Flip vs. BRRRR: How Does the Exit Change the Math?

A flip repays the line from sale proceeds. A BRRRR repays it with a cash-out refinance after the rehab and lease-up. The line has to survive the whole holding period in either case.

On a flip, the risk is time. Interest accrues on the drawn balance while the property is listed, and the draw is interest-only, so the balance doesn’t fall until you sell.

On a BRRRR, the risk is the appraisal. If the refinance appraises low, the cash-out returns less than planned and you cover the HELOC shortfall yourself. The rehab has to lift value enough for the new loan to pay off the line.

A DSCR refinance is the usual exit. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across our wholesale network, DSCR cash-out loans top out around 75% LTV, with roughly 6 months of seasoning as the common expectation. Select programs start at 1.00 coverage, and stronger ratios open better leverage and pricing. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. HELOC debt on a different property generally does not enter the new property’s coverage calculation, though that depends on the file.

Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to the full payment only. Repairs, vacancy, management, and utilities sit outside it. The complete DSCR loans guide walks through the mechanics.

What Can Freeze or Shrink an Undrawn Line?

A lender can stop further draws. The CFPB explains that if home value falls significantly, a lender may decide not to allow additional credit. It adds that a lender may also freeze draws if your financial circumstances change and it doubts you can repay.

So undrawn credit is not committed project money. Because at least 75% of the line is drawn at closing, the amount that could be frozen is the remaining 25% or less. Still, a rehab that plans to draw late should not assume that money will be there.

How Do Valuation and Documents Affect the Amount?

An investment line is capped at $500,000, and full appraisals are required only above $500,000. So an investment HELOC normally sits in the automated-valuation lane and commonly closes with no traditional appraisal. A higher CLTV may require a secondary valuation, and you may request a full appraisal in any case.

Credit details to plan around:

• Minimum 700 on an investment property, using a single-bureau score keyed to the primary wage earner.
• Credit report no older than 90 days at closing, with no rescores.
• Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history follows a 7-year path, and deed-in-lieu, pre-foreclosure, or short sale a 4-year path.
• Borrowers are limited to three lines. Anyone owning more than 15 financed properties is not eligible.

Also note availability. These lines are offered only in Lendmire’s 16 full-service states, narrower than its DSCR footprint.

HELOC, DSCR, or Hard Money: Which Fits?

When the money is for a single flip, a HELOC is often a more affordable bridge if you have the equity. When the goal is to scale BRRRR cycles, DSCR financing tends to scale better because it looks at each property’s rent, not your personal ratios. A rental held in an LLC points toward DSCR, since a HELOC can’t be placed on an LLC-titled property.
