How Much Can You Borrow on an Investment Property HELOC to Fund Rehab in Stages?

The Quick Read: It depends on your equity, not your rehab budget: on an investment property, the line tops out at 70% of the property’s current value minus every loan already on it, capped at $500,000, and at least 75% of that line is drawn at closing, so staging is limited.

• The ceiling is 70% combined loan-to-value (CLTV) on an investment property, and a credit score above 700 buys no extra leverage.
• Lines run from $25,000 to $500,000, with a 5-year interest-only draw period and then 25 years of repayment.
• Value is measured as the property stands today, so after-repair value does not raise the limit.
• Staging is limited, so a plan that relies on drawing only as costs arise rarely fits.
• Rentals held in an LLC do not fit this product. DSCR cash-out is the usual alternative. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

How Is the Maximum Line Calculated?

The maximum line is the property’s current value times 70%, minus the first mortgage and any second lien. That is the whole formula. Your rehab budget, your credit score above the 700 floor, and the property’s rent never enter it.

Here is how it plays out in percentages of value. Say your first mortgage sits at 55% of the property’s value. The 70% ceiling leaves room for a line of at most 15 points of value. If your first mortgage sits at 40% of value, the room is 30 points.

The $500,000 line cap only matters on higher-value properties. On most rentals, the 70% ceiling binds first. The $25,000 floor matters at the other end. A heavily mortgaged property can leave so little room that the line falls below the minimum, and then there is no line at all.

Think of the formula as a leftover. The lender sets the total debt allowed on the property, and the line is whatever space remains after the first mortgage.

Across the wholesale network Lendmire works with, this sizing logic is consistent.

Key Terms Defined

Combined loan-to-value (CLTV) is every loan secured by the property, added together, divided by the property’s value.

Draw period is the window when you can borrow from the line. On an investment property here, it lasts 5 years and payments are interest-only.

Repayment period is the phase after the draw ends. The line stops lending and amortizes over 25 years.

Closing draw is the minimum amount you must borrow when the line opens. Here it is at least 75% of the approved line.

After-repair value (ARV) is what the property is expected to be worth once the work is finished. A home equity line does not lend against it.

Lien position is where the line ranks behind other loans on the property. A line can sit in first or second position.

Why Doesn’t the Rehab Budget Set the Limit?

Because the lender sizes the line on what the property is worth now. Unfinished work does not count, and the planned renovation does not raise the ceiling. A rehab that would add real value later gives you no extra room today.

A line that covers a rehab is therefore a matter of arithmetic. If your equity room is larger than the first phase, you can fund it. If the room is smaller, the line falls short no matter how strong the project looks on paper.

Valuation also works differently than most investors expect. Because an investment line caps at $500,000, it normally runs on an automated valuation rather than a traditional appraisal. You can request a full appraisal if you want one. NerdWallet notes that some lenders on investment-property lines may require multiple appraisals, so valuation practices differ across the market.

A low valuation hurts in a specific way. The line shrinks by the ceiling’s share of the lost value, and your first mortgage does not shrink to make room. A modest dip in value can push a thin file below the $25,000 minimum.

An automated valuation also will not credit a fresh rehab. If you finish phase one and want to resize the line, expect the new number to reflect only what the data can see.

Can You Really Draw in Stages?

Only partly. At least 75% of the approved line is drawn at closing, and interest runs on the drawn balance from the first day. That makes this a mostly lump-sum product with a small reserve for later phases.

Later draws carry a $1,000 minimum, with one state setting it higher. The draw window ends at year 5. After that, you repay principal and interest over 25 years.

You open the line and draw at least 75% at closing. Later, you take a draw of roughly 10% of the line for a rehab phase. That leaves about 15% still available, and everything must be drawn before year 5 ends.

Do the staging logic in your head before you apply. If the first phase costs far less than 75% of the line, you will be holding drawn cash that sits idle. That cash still carries interest. If the first phase costs more than the line allows, later phases can only draw from the undrawn remainder.

Opening a line early and drawing late does not fit this product, because most of the line is funded at closing.

On this product, pricing floats through both the draw and repayment periods and does not convert to fixed. The federal CFPB booklet on home equity lines explains that plans with variable pricing can change your payment over time, and that each plan sets a fixed draw period followed by repayment or renewal.

Market-wide, draw periods can run up to about 10 years, according to the same NerdWallet page. On this network’s investment-property lines, the draw period is 5 years, and that is the figure to plan around.

How Do You Size the Line Around Phase One?

Size it around the first phase of work, not the whole project. The line is mostly drawn on day one, so the first phase should account for most of the dollars you plan to pull.

A practical approach starts with a simple list. Write down the phase-one cost and the cost of each later phase. Then compute your equity room with the formula above.

• If phase one fits comfortably inside 75% of the line, the structure works with little idle cash.
• If phase one is much smaller, the line is probably too large for your first phase, and you will carry extra interest on unused money.
• If your equity room only covers phase one, treat later phases as funded from another source, such as cash flow or a different loan.

Another option is to let the rehab itself raise the next line. After phase one is complete and the property is worth more, you could revisit the equity picture. This is a planning idea, not something to count on, because value is measured by an automated model unless you ask for a full appraisal.

Qualifying also uses the largest possible payment. The maximum debt-to-income ratio (DTI) is 50%, and it is calculated on the interest-only payment on the maximum draw. That means you are tested as if you borrowed all of it, even if you plan to draw less.

What Can Go Wrong Mid-Rehab?

The two big risks are a stalled project and a shrinking equity cushion. Each one runs into the same hard dates and caps.

A stalled rehab collides with the end of the draw period. Contractors slip, permits drag, and a project planned for one phase can run into year 5. When the draw ends, undrawn room disappears and payments shift to principal plus interest over 25 years.

Pricing risk adds to this. Because pricing floats, the carrying cost of the drawn balance can change while the work is unfinished and the unit is empty. Budget for interest-only carry through the full rehab and the lease-up, not just the construction months.

A lower-than-expected valuation is the third risk. It cuts the line before you draw, and it can sink the file if the resized line falls under $25,000.

One more point is worth keeping. At a 70% ceiling, at least 30% of the property’s value stays untouched. That cushion protects you and the lender. It also means the HELOC can never fund a project that needs more equity than you own.

Who Qualifies for an Investment Property HELOC?

You qualify on personal credit, DTI, and equity, not on rent coverage. The minimum credit score is 700, and the DTI cap is 50%. Title must be held in your own name or in a revocable living trust.

The product is a standalone line in first or second lien position. Eligible properties include single-family homes, 2-4 unit properties, 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. A borrower owning more than 15 financed properties is not eligible.

Title is the sharpest dividing line. LLCs, corporations, partnerships, and irrevocable, land, or blind trusts cannot hold title. If your rental is already deeded to an LLC, you need either a vesting change or a different product.

This line is also available in a narrower set of states than the DSCR footprint. Lendmire’s home equity line offering covers 16 full-service states, while its DSCR investor programs reach 41 markets, including Washington, D.C.

Yahoo Finance reports that lenders weigh both your credit and the property’s finances, and that investment-property lines carry stricter criteria than lines on a primary residence. It also cites a 20% minimum equity stake for an investment property in market surveys. On this network, the investment-property ceiling is 70% CLTV, which keeps at least 30% equity in place.

If you want to look at the full picture, Lendmire’s complete DSCR loans guide walks through the other route many investors use.

When Does DSCR Cash-Out Fit Better?

When the rental sits in an LLC, when the rehab needs more equity than a 70% CLTV line leaves, or when you want rent coverage rather than personal DTI to carry the file. DSCR cash-out replaces your first mortgage and releases equity in one loan.

A debt service coverage ratio (DSCR) loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Placing one in an LLC’s name is possible, subject to lender program eligibility.

On a cash-out refinance of a standard rental, leverage across most of the network tops out around 75% LTV, and about 6 months of seasoning is the common expectation. That is a different structure from the line. It pays out proceeds as a lump sum, and you accept a new first mortgage in exchange. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

A rehab loan is built for the staged use case. It sizes on project cost and ARV, and releases funds in draws against a documented budget. The HELOC does not do that.

Keep a ledger of every draw and what it paid for.
