How Much Can You Borrow on an Investment Property HELOC as a BRRRR Investor?

The Quick Read: Usually up to 70% combined loan-to-value (CLTV) on an investment property, minus every lien already on it. The line is capped at $500,000 and sized on today’s value rather than the after-repair value of your BRRRR project, and a 700 credit score is the entry point. The line goes on a property you already own, not the one you are about to buy. Everything below is subject to lender guidelines and full file review.

• The ceiling: 70% CLTV on an investment property, at both 700 and 720 credit scores.
• The size: lines run from $25,000 to $500,000 on investment property.
• The collateral: a rental you already own, titled to you personally or to a revocable living trust.
• The qualifier: your credit, income, and debt-to-income ratio, not the rental’s coverage ratio.
• The exit: most BRRRR investors repay the line with a DSCR cash-out refinance once the rehab is done.

How Is the Maximum Line Calculated?

The maximum line is the property’s current value times the CLTV ceiling, minus every lien already on the property. Credit, debt-to-income, and the valuation can trim it further. The line cannot exceed $500,000 on an investment property.

Here is a mini-picture. Say you own a seasoned rental with a first mortgage equal to 45% of its value. The ceiling is 70%, so the most room you have is 25% of the property’s value. Any trims come off that number.

Run the same math on a rental with a first mortgage at 60% of value. Now you have 10% of value to work with. That is why a property you already leveraged heavily often yields little.

Two limits sit on top of the percentage:

• The cap: on a high-value property, the $500,000 line limit binds before the 70% ceiling does.
• The floor: if the room left over would produce a line under $25,000, there is no line to write.

The line can sit in first or second lien position. Either way, the first-lien balance counts in the CLTV math.

Why Is the Investment Ceiling Lower Than on a Home?

Lenders treat rentals as riskier collateral than a primary home. NerdWallet notes that investment-property HELOCs are possible but not offered by every lender, and that maximum loan-to-value is generally lower than on a primary residence.

Across the wholesale network Lendmire works with, the tiers are tied to occupancy. On an investment property, the ceiling is 70% CLTV. Primary-residence and second-home lines can reach 90% CLTV, but only at a 720-or-better credit profile.

Market figures vary by lender. In this network, the investment floor is 700, and a 720 score reaches the same 70% ceiling. A higher score adds eligibility, not leverage.

The higher primary-home tiers carry a trade-off. Borrowing against your own home puts that home at risk if a rehab stalls. A larger line also needs a full appraisal and a primary residence as the securing property.

Which Property Should Secure the Line?

Secure it with a property you already own, because you cannot borrow against the BRRRR property you have not closed on. For most investors that means a seasoned rental or the primary home.

The title matters too. The property must be held by you as an individual or by an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on this product. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

Eligible property types are single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.

What Do Lenders Underwrite on a HELOC?

They underwrite you, not the rent. A standard investment-property HELOC is reviewed on your credit, income, and debt-to-income ratio (DTI), which compares your monthly debts to your monthly income. The rental’s DSCR is not the test.

Typical network parameters, subject to lender guidelines:

• Credit: 700 minimum on an investment property, with no tier beneath it. The credit report is single-bureau and no more than 90 days old at closing.
• DTI: 50% maximum, qualified on the interest-only payment calculated on the maximum draw. A ratio above 45% requires a 680 score or better, which the 700 investment floor already clears.
• Draw at closing: at least 75% of the approved line is drawn when the loan closes.
• Structure: a 5-year interest-only draw period followed by a 25-year repayment period.
• Exposure: a borrower is limited to three lines, and owning more than 15 financed properties makes you ineligible.
• Listings: a property listed for sale, or listed within the past 60 days, is ineligible in several states.
• Availability: the HELOC product is offered in 16 states, narrower than Lendmire’s DSCR footprint of 41 markets, including Washington, D.C.

The 75% draw rule shapes your BRRRR plan. You carry most of the line from the first day. Size the line to what the project needs, not to the maximum you can get.

How Is the Line Valued?

The line is sized on what the property is worth today, not on what it will be worth after your rehab. Do not count on a rehab to enlarge a line.

Because investment lines cap at $500,000, they usually run on an automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation. You can also ask for a full appraisal in any case. NerdWallet adds that multiple appraisals may be required on some rental HELOCs.

Automated models see the property as it sits now. A fresh renovation may not show up in them, and that is another reason to plan on current value only.

Why Can a Line Shrink Mid-Rehab?

The line is not locked in at the amount you were approved for. Lenders may freeze or reduce it if the property’s value drops significantly. The CFPB’s HELOC booklet lays out the same sizing method: take a percentage of appraised value and subtract the mortgage balance.

The booklet is written for owner-occupied homes, so it does not set a rental limit. No agency sets a cap for investment-property lines either. Each lender and program sets its own CLTV, credit floor, and line size.

If you are halfway through a rehab and a line gets cut, you have to fund the rest yourself. Keep a cash buffer outside the line.

How Does the HELOC Fit Into the BRRRR Cycle?

The HELOC is the bridge, and the refinance is the real constraint. BRRRR stands for buy, rehab, rent, refinance, repeat. The line covers the down payment, closing costs, and rehab or holding costs. A refinance then pays it off.

The sequence looks like this:

1. Open the line first. Set it up on a rental you already own, before you take on more leverage elsewhere.

2. Buy and rehab. Draw for the down payment and the work.

3. Rent it. Get a lease in place so the property shows its income.

4. Refinance. Most BRRRR investors use a DSCR cash-out refinance, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

5. Repay the line. The refinance proceeds retire the HELOC and free the room to use it again.

For a standard rental, a DSCR cash-out refinance tops out at about 75% LTV across most of the network. About 6 months of seasoning is the common expectation. Short-term rental collateral is more restrictive, with cash-out at 70% LTV. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Plan the refinance before you buy. If the appraisal comes in low or the lease-up drags, you are carrying a variable-price line with no exit.

HELOC or DSCR Cash-Out: Which Do You Use?

They do different jobs, and many BRRRR investors use both. The HELOC funds the front end. The DSCR cash-out replaces it on the back end.

The DSCR is monthly rent divided by PITIA, which is principal, interest, taxes, insurance, and any association dues. Clearing the program’s coverage minimum does not mean the property cash flows. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Treat 1.00 as where many select programs start, not as a standard. Stronger ratios open better terms and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Investors with many properties or LLC-titled rentals often skip the HELOC and go straight to DSCR. The complete DSCR loans guide covers how that exit works in detail.

What If the Rental Is in an LLC?

If your rental sits in an LLC, the HELOC cannot go on it. This is the sharpest difference from a DSCR loan, which can lend to an LLC, subject to program terms. You have two options: deed the property into your personal name or a revocable trust first, or use a DSCR cash-out refinance instead.

Retitling has side effects. Review insurance, your lender’s terms, and any liability concerns before moving a property out of an LLC. Many investors choose the DSCR cash-out refinance for LLC-owned properties and use the HELOC only on a personally titled property.

If you own the property free and clear, a first-lien line is also possible.
