HELOC Requirements for Refinancing a Balance Into a New HELOC

The Quick Read: A new home equity line that pays off your old one is underwritten from scratch, on you and on the combined loan-to-value of the property, and across our wholesale network the occupancy type sets the ceiling, the credit floor, and the maximum line size. Rent does not qualify you for a line. Here is what matters most:

• Occupancy sets the ceiling. An investment-property line tops out at 70% CLTV with a 700 minimum credit profile. Primary residences and second homes can reach 90% CLTV, only at 720 or better.
• The new line’s limit counts, not just your payoff. Lenders add the first mortgage and the full new limit, then divide by current value.
• Personal underwriting applies. Debt-to-income tops out at 50%, and the test uses the interest-only payment on the maximum draw.
• Title can end the deal. An LLC cannot hold title on these lines. A property already deeded to one needs a vesting change or a DSCR cash-out instead.
• Availability is narrower than DSCR. Lendmire places these lines in 16 full-service states, versus its 41-market DSCR footprint.

What Does “Refinancing a Balance Into a New HELOC” Mean?

It means a brand-new credit line pays off the old one. Nothing about the old line is modified. The old lien is released at payoff, and the new line gets its own limit, its own draw period, its own repayment period, and its own underwriting.

A HELOC (home equity line of credit) is a revolving line secured by the property. You borrow against the equity, repay, and borrow again during the draw period. Investors often use one for down payments or rehab. Then the draw period ends, the payment jumps, and the question shows up: can I roll this into a fresh line?

Sometimes yes. It depends on three things: the equity you have today, the occupancy of the property, and how the title is held. The value that counts is today’s appraised or automated value. The value when you opened the line is history.

Switching lenders adds a wrinkle. A new lender may be stricter than your original one, particularly if values have slipped. You are not renewing a relationship. You are applying again.

Requirements at a Glance

Across the network, the requirements split sharply by occupancy. The same borrower can face a very different answer on a rental than on a home they live in. Every figure below is an eligibility range, subject to lender guidelines and full file review.

A few notes on that table. On a primary residence, a line above $500,000 caps at 75% CLTV and needs a full appraisal. Lower credit tiers step the ceiling down. A 620 profile on a primary residence tops out at 70% CLTV, and a 600 profile at 60%. Second homes and investment properties never go below their own credit floors.

Two draw structures exist. One is a 3-year interest-only draw followed by a 17-year fully amortizing repayment (the 3/17 structure). The other is a 5-year draw followed by a 25-year repayment (the 5/25 structure). Investment lines run the 5/25 structure only. Pricing floats through both the draw and the repayment period and never converts to fixed.

One more detail matters for balance refinances. At least 75% of the line is drawn at closing. You cannot open a large line and leave most of it idle. The line should roughly match what you actually need.

How Underwriting Treats Your Existing Balance

The old balance is a payoff item. It does not shrink what the new line has to satisfy. Underwriting runs in this order:

1. Equity test. The lender adds the first mortgage and the new line’s full limit, then divides by the property’s current value. That result is your CLTV. It has to sit under the ceiling for your occupancy and credit tier.

2. Credit review. A single-bureau score keyed to the primary wage earner sets your tier. The report cannot be older than 90 days at closing, and there are no rescores.

3. Debt-to-income. The maximum is 50%. It drops to 45% for scores from 600 to 679. Above 45%, you need at least 680. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.

4. Valuation. Lines at or below $500,000 ordinarily run automated valuation with no traditional appraisal. A higher CLTV may trigger a secondary valuation. A full appraisal is required above $500,000, and you can request one in any case.

5. Payoff. The new line pays the old one off, and the old lien is released.

Step 3 is where investors get surprised. A HELOC counts your personal debts. Rental income does not carry the file. Mortgages on other properties sit in your ratio, so a larger portfolio makes this test harder.

The portfolio itself has limits too. A borrower can hold at most three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Those are the two wholesale programs behind these lines: the higher-leverage one reaches the 90% tier, and the longer-runway one carries the 5/25 draw. A borrower with more than 15 financed properties is not eligible.

A Worked Example, in Percentages

Run the numbers on an investment property, using modeled assumptions rather than market data. Say the first mortgage equals 40% of today’s value. You want a new line sized at 25% of value to pay off the old balance and leave a little room.

CLTV: 40% + 25% = 65%. That sits under the 70% investment ceiling, so the equity test passes, assuming a 700 or better score and a clean ratio.

Now change one input. A new line sized at 35% of value gives a 75% CLTV. That fails on an investment property. The fix is a smaller line, a paydown at closing, or a different product.

Notice what did not matter: the old line’s original limit. Only today’s value, today’s first mortgage, and the new limit count. Falling values can sink a refinance that looked safe on paper. (A line opened at a peak is the classic casualty.)

Key Terms Defined

CLTV (combined loan-to-value): the first mortgage plus the new line’s limit, divided by the property’s current value.

Draw period: the stretch when you can borrow up to the limit, usually paying interest only.

Repayment period: the stretch after the draw ends, when the balance amortizes and the payment rises.

Lien position: whether the line sits first or second in line for repayment. These lines can be a standalone first or second lien.

Vesting: how title is held, such as an individual or a revocable living trust.

DSCR (debt service coverage ratio): monthly rent divided by the full monthly payment on the property, including principal, interest, taxes, insurance, and any HOA dues.

What Changes and What Stays

The collateral stays. Almost everything else changes.

• Draw period: the new line starts its own clock under its own structure. Some lenders outside our network treat this differently, so confirm it on any line you consider.
• Pricing: it floats across the draw and repayment periods. Do not count on a fixed-pricing feature.
• First mortgage: a standalone line leaves it alone. That is the big contrast with a cash-out refinance of the first loan.
• Fees: expect possible appraisal, application, and closing costs. The CFPB booklet on home equity lines lists these and notes that some lenders waive some or all of them.
• Credit: you will see a hard inquiry on the application.

A balance refinance is not a pricing swap. It is a new loan with new terms. If you want the broader picture of bigger-line scenarios, Lendmire’s piece Second HELOC vs Refinancing Your Existing Line Into a Larger One goes deeper.

Where the General Rule Breaks

Five edge cases cause most failed balance refinances.

The rental-use clause. The CFPB booklet warns that renting out your home may be prohibited under the terms of a line. Read the occupancy language in any agreement you sign. A line written against a primary residence is not a license to run it as a rental.

Title held by an entity. Fee simple or leasehold title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. Rental-focused investor education notes that fewer lenders write lines on rentals and that entity titling is a common obstacle. Moving a deed into your name can trigger other consequences, so think it through before you do it.

A freeze or reduction. Lenders can freeze or cut a line when values fall or finances worsen, per the same CFPB booklet. If that already happened, a new line may be hard to get, because the same value drop hurts your CLTV. Lendmire’s article Waiting Out a HELOC Freeze vs Refinancing Into a New Second Lien covers that fork.

Ineligible property. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. Single-family, 2-4 units, PUDs, townhomes, and condominiums (including non-warrantable ones) are. Modular factory-built homes work on the longer-runway program only.

Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program. One seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines that history regardless of age.

One more note on use of funds. Tax treatment varies; consult a qualified professional before relying on any deduction.

Common Reasons for Denial, and the Fix

Most denials trace to one of these:

• CLTV too high. Shrink the line, pay down the first mortgage, or wait for value to recover.
• Credit under the occupancy floor. An investment line wants 700. A second home wants 640. Fix the score before applying.
• Ratio over the cap. Recall that the lender tests the maximum draw. Pay down other debts or request a smaller line.
• Title in an entity. Change vesting, or skip to a DSCR cash-out.
• Property type. Nothing fixes a manufactured home. Pick another route.

Gather your documents before you apply. Expect proof of income and assets, such as traditional personal-income documentation, pay stubs, or bank statements, plus government ID, current insurance, and the existing line’s statement. Three tradelines on file help too. The longer-runway program wants two tradelines seasoned 12 months or one seasoned 24.

HELOC or DSCR Cash-Out: Which Fits?

If the property is a rental and the numbers get tight, a DSCR cash-out refinance is often the cleaner path. A DSCR loan is a business-purpose investor loan, so it is reviewed differently from an owner-occupied mortgage. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Here is the honest tradeoff. A line costs less when you need flexibility. A DSCR cash-out wins when title, ratio, or leverage block the line. The cash-out uses its own LTV scale. Across most of the network it tops out around 75% LTV on a standard rental, and short-term-rental collateral sits lower. About 6 months of seasoning is the common expectation. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Coverage is where DSCR starts. A 1.00 coverage ratio is where many select programs begin. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Most programs want a score near 660, a 620 floor exists in parts of the network, and 700 or better unlocks the strongest tiers. Reserves vary by lender, leverage, and loan size, and commonly run around 6 months of PITIA. Your complete options are laid out in Lendmire’s complete DSCR loans guide.

One warning. Clearing 1.00 does not mean the property cash flows. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Treat the ratio as a lender’s test, not a profit forecast.
