How Much Can You Borrow on an Investment Property HELOC Across a BRRRR Pipeline?

The Quick Read: Usually you can borrow up to 70% combined loan-to-value (CLTV) on a single investment property, minus the mortgage already on it, with a line of $25,000 to $500,000, because each line is sized against one property you already own and never against the whole BRRRR pipeline or the property you are buying. BRRRR means buy, rehab, rent, refinance, repeat. A home equity line of credit (HELOC) is one way to fund the early steps, and the refinance is what repays it.

• The formula: property value × 70% CLTV, minus the first mortgage balance, on an investment property.
• The dollar cap: lines run from $25,000 to $500,000 per line, subject to lender guidelines.
• The credit floor: 700 is a hard minimum on an investment line, and 720 reaches the same 70%.
• The pipeline rule: equity in one rental cannot back a line on another, and the BRRRR property you are buying cannot secure the line.
• The title rule: the property must be held by you or your revocable living trust, not an LLC.

How Is the Limit Calculated on One Rental?

The limit is the property’s value times the CLTV cap, minus what you already owe. On an investment property in Lendmire’s wholesale network, the cap is 70% CLTV. CLTV adds your first mortgage balance and the requested line, then divides by the property’s value.

Run the numbers with percentages. Say a rental’s first mortgage sits at 50% of its value. The 70% ceiling leaves room for a line worth 20% of value. If the first mortgage is only 30% of value, the room is 40% of value, but the $500,000 cap can still bind first.

That dollar cap matters most for larger holdings. A property with substantial equity can hit $500,000 before it hits 70% CLTV. The calculator on this page gives an illustrative estimate once you enter your own value and balance.

Your credit score does not stretch the ceiling. On an investment line, 700 and 720 both reach 70% CLTV. A higher score buys a cleaner file, not extra leverage. Primary residences and second homes sit on a different table, which is why the occupancy of the property matters before anything else.

The idea that a HELOC limit comes from appraised value minus the existing mortgage is standard across the industry. The Consumer Financial Protection Bureau describes a HELOC as open-end revolving credit, with available equity equal to the home’s value minus the mortgage balance. NerdWallet adds that the lender pool for rentals is smaller and you cannot borrow as much as against a primary home.

Why Does “Across a Pipeline” Change the Answer?

Each line is secured by exactly one property, so the pipeline never pools. Your total borrowing power across several BRRRR deals is the sum of separate, property-by-property tests. Each seasoned rental that qualifies gets its own CLTV math, and the weakest equity position in the group stays weak.

Two structural rules shape everything:

• The line goes on a property you already own. It cannot sit on the BRRRR property you are about to buy, because that property has little usable equity early on.
• The line cannot borrow against a different property’s equity. A rental with a low balance can back its own line, but not the next deal’s.

Across the network, a borrower is limited to three lines. Combined exposure is capped at $2,000,000 on one of the two wholesale programs behind these lines and $750,000 on the other. A borrower with more than 15 financed properties is not eligible.

Here is how capital typically moves across cycles.

Repeated cycles do not recreate your equity automatically. After the refinance, the new loan on the BRRRR property replaces the old one, and the repaid line can be drawn again only if the collateral property still fits under its cap. This is why scaling is really a game of rotating collateral.

What Do Lenders Check Before Setting the Line?

They test you, not the rent. This is a personal-credit product, so the file turns on credit, income and total debt. It does not turn on whether the rent covers the payment. That is the biggest difference from a DSCR loan, which looks at the property.

Here is what the file covers on an investment line:

• Credit: 700 minimum, using a single-bureau score keyed to the primary wage earner, with the report no more than 90 days old at closing.
• Debt-to-income: 50% maximum, calculated on the interest-only payment at the maximum draw. Borrowers in the 600 to 679 credit range face a 45% limit, but investment lines already floor at 700.
• Structure: a standalone line in first or second lien position, with a 5-year interest-only draw and a 25-year fully amortizing repayment.
• Draw at closing: at least 75% of the line is drawn at closing, and pricing floats across the draw and repayment periods.
• Valuation: a $500,000 cap keeps an investment line in the automated-valuation lane, so a traditional appraisal is not usually needed. A higher CLTV may call for a second valuation, and you can request a full appraisal.
• Documents: the current first-mortgage statement, the insurance declaration and the vesting deed.

A bank-style line from a depository lender is often built differently. The network’s investment line runs a 5-year draw instead.

Bank-statement income changes only how your income is counted, and it does not change the 70% CLTV, the 700 credit floor or the $500,000 limit. These lines are offered in a smaller set of states than the DSCR footprint: the 16 states where Lendmire offers full-service lending.

Where Does the Line Fit in the BRRRR Sequence?

It sits at the front, funding the purchase or the rehab, and the refinance sits at the back, repaying it. Investors commonly pull from a line on a rental they already own, buy and renovate the next property, then refinance after rent-up to pay the line down.

The refinance side deserves its own attention. A DSCR cash-out refinance on a standard rental tops out around 75% LTV, with about 6 months of seasoning as the common expectation. Seasoning is the waiting period a lender wants between buying or refinancing a property and the next cash-out. Lenders in the network order their own appraisal for value and market rent, and they size the loan at the lower of the value limit or the rent-coverage limit. They do not use your after-repair-value estimate. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

DSCR is the ratio of monthly rent to the full monthly obligation (PITIA: principal, interest, taxes, insurance and any association dues). It is not the same as positive cash flow. Repairs, vacancy, management, utilities and capital spending sit outside the calculation.

Some points trip investors up in the middle of the sequence:

• Borrowed down payments still follow the purchase lender’s rules. Reserves and source-of-funds checks apply even when the cash came from a line.
• Borrowed money is close to 100% financing. If you borrow the down payment against a different property, the new rental still needs to cover its own costs plus the line payment.
• Equity in the BRRRR property is thin early. Do not count on it as collateral for the next deal.
• Seasoning on the exit varies by lender. Treat the six-month expectation as common, not universal.

What Are the Edge Cases?

Most of the surprises come from title, credit and property type. Check these before you plan a pipeline around a line.

LLC-owned rentals. An LLC, corporation, partnership, or irrevocable, blind or land trust cannot hold title on this product. Title must sit with you or your revocable living trust. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead, which can generally keep the LLC on title, subject to program terms.

Credit between 620 and 699. The investment line has no tier below 700. These borrowers usually look at a DSCR cash-out refinance instead, where a 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage.

Needs above $500,000. A line above $500,000 is for primary residences only, needs a full appraisal, and caps at 75% CLTV. It requires a 700 credit profile or better, or 720 on the longer-runway structure. An investment property cannot use it, so larger needs usually point to a cash-out refinance.

Recently bought or refinanced properties. A fresh BRRRR property is generally not line-eligible. That is another reason the line has to sit on an older rental.

Property types. Single-family homes, 2-4 units, PUDs, townhomes and condominiums (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned property are not offered.

Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path after foreclosure and 4 years after a deed-in-lieu, pre-foreclosure or short sale.

HELOC or DSCR Cash-Out: Which Fits the Pipeline?

A HELOC fits when the rental is titled personally, the need sits under the cap, and you want to keep the existing first mortgage. A DSCR cash-out fits when the property is in an LLC, the need is large or the portfolio is big. Many investors use both, assigning each to the properties where it fits.

The tradeoff runs both ways. A HELOC leaves a first mortgage you may want to keep. A cash-out reaches a higher leverage point on standard rentals, but it replaces the old loan and starts a new clock.

What Are the Risks Across Several Cycles?

The risks stack as the pipeline grows. A line is borrowed money secured by a property you own, so a missed payment puts that property at risk. If the collateral is your primary home, the stakes are higher.

• Line reductions. The CFPB’s HELOC brochure notes that lenders may reduce your credit line if the home’s value drops materially. A frozen line mid-rehab can strand a project.
• Floating pricing. Pricing floats and never converts to fixed on these lines, so the payment can rise. Test your deals against a higher payment before you borrow.
• The draw clock. Interest-only payments run during the 5-year draw, and the repayment period then begins. A slow rehab or lease-up eats into that window.
• A refinance that comes up short. If the lender’s appraisal or market rent lands below your plan, the cash-out may not repay the line in full.
• Stacked exposure. Three lines, several first mortgages and new purchase loans add up. Cap your total before you start.

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Lendmire arranges financing as a broker through select lenders in its wholesale network, and all figures are subject to lender guidelines and full file review. This is not a commitment to lend.

A BRRRR pipeline grows by rotating collateral, so the investors who keep scaling are the ones who track which property secures which line before they buy the next one.
