"What Does CLTV Mean on a Second Mortgage or HELOC? The Formula and How Much You Can Borrow"

The approval letter for your home equity line of credit (HELOC) says the line was sized at 85% CLTV, and nothing else on the page says what those four letters mean. The percentage is built from your first mortgage balance, the new loan and your home's value, and the lender's maximum CLTV is what turned your equity into a smaller amount than you had counted on.

Combined loan-to-value, or CLTV, is every mortgage on your home, your first mortgage balance plus the full amount of the new second mortgage or home equity line, divided by the home's value. On Quorum's HELOC guideline sheet dated May 2026, the maximum CLTV reaches 95% for a 720 credit score on a one-unit home you live in.

On Luxury Mortgage's guideline sheet, the same kind of limit drops to 60% for a second mortgage that pays you cash on an investment property with a 680 score.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, licensed in fifteen states, NMLS #483943, through C2 Financial Corporation. Each lender publishes a guideline sheet, a chart of its limits. This page uses the guideline sheets of three lenders I work with. Quorum is a credit union. Angel Oak publishes one guideline sheet for its home equity line and its closed-end second mortgage, a second mortgage paid out in one fixed amount at closing, unlike a line you draw on. Luxury Mortgage publishes guidelines for what it calls Simple Seconds. For the dollar amount, see how much you can borrow with a HELOC. The home equity hub compares a home equity line, a second mortgage and a cash-out refinance state by state.

What is combined loan-to-value on a second mortgage?

Loan-to-value compares one loan to the home. The CFPB defines it as "a measure comparing the amount you are financing with the appraised value of the property." On a first mortgage, that one loan is the whole story.

A second mortgage or a home equity line is a second claim on the same home, standing behind the first, so the lender adds the two together before it divides. Luxury Mortgage's Simple Seconds guidelines, version 3.0 dated May 12, 2026, say the CLTV ratio is "calculated by dividing the total of all liens (First Mortgage Loan Amount + all subordinate financing, including the credit limit of any Home Equity Lines of Credit regardless of amount drawn) by the value to be utilized for the transaction." The total of all liens is the claims every lender has on the home.

Your first mortgage balance counts in that total, and the new second mortgage counts at its full amount. On a home equity line the full amount is the credit limit, so the amount you plan to draw does not change the ratio.

If you already have a line on the home, Luxury counts its full credit limit whether you have drawn ten dollars or all of it. An older line with nothing drawn can still push your total past the maximum CLTV.

The value the lender uses is, in Luxury's words, "the lower of the sales price, documented cost, or the current appraised value." Quorum's guideline sheet dated May 1, 2026 uses the lower of the purchase price or the appraised value if you bought the home less than six months ago.

For where that value comes from, see do you need an appraisal for a HELOC.

Your credit score, how you use the home and the size of the loan each move the maximum CLTV.

The CLTV formula, in both directions

First mortgage balance
+ Full amount of the new second mortgage or line
= Total of all liens
÷ Home's value, the lender's figure
= CLTV

Home's value, the lender's figure
× Lender's maximum CLTV for your row
= Maximum total of all liens
- First mortgage balance
= Most you can borrow in a second mortgage or line

A worked example, with invented figures

These figures are invented to show how the math works.

Say your home is worth $450,000 by the lender's valuation, your first mortgage balance is $290,000, and the lender's maximum CLTV for your file is 85%.

Home's value                            $450,000
Lender's maximum CLTV                       85%
Maximum total of all liens              $382,500
First mortgage balance                 -$290,000
                                        --------
Most you can borrow                      $92,500

Your equity is $160,000, the value less the balance. Your CLTV before any second mortgage is about 64.4%, the balance divided by the value. At 85%, the lender counts only $382,500 of the home's value, so the most you can borrow is $92,500, smaller than your $160,000 in equity. The difference is the share of the home the lender requires you to keep.

On the same home, a 95% maximum CLTV leaves $137,500, an 80% maximum CLTV leaves $70,000, and a 75% maximum CLTV leaves $47,500.

Your credit score and the maximum CLTV

Each guideline sheet publishes its maximum CLTV by credit score, for a one-unit home you live in. Angel Oak's home equity line rows in the table are its full-documentation rows, where income is verified with tax returns and pay records. Luxury's rows are for a second mortgage that pays you cash, on a home you live in.

Lender, sheet and product	Credit score	Maximum CLTV
Quorum HELOC, May 1, 2026	720 and up	95%
Quorum HELOC	680 to 719	90%
Quorum HELOC	640 to 679	80%
Angel Oak HELOC, May 8, 2026	760	90%
Angel Oak HELOC	720	85%
Angel Oak HELOC	680 or 660	75%
Angel Oak closed-end second mortgage, same sheet	720	90%, loan up to $500,000
Angel Oak second mortgage	700	85%
Angel Oak second mortgage	680	90%, loan up to $400,000
Angel Oak second mortgage	660	80%
Luxury Simple Seconds, cash-out, May 12, 2026	740	85%
Luxury Simple Seconds, cash-out	720	80%
Luxury Simple Seconds, cash-out	700 or 680	70%

On the invented home above, Quorum's 720 score (95%) and its 640 to 679 band (80%) leave you $67,500 apart in what you can borrow, and its 680 to 719 band (90%) lands between them at $115,000.

The lender reads one of your three scores, and what credit score you need for a HELOC covers which one.

Home use and the maximum CLTV

The home you live in gets the highest maximum on all three sheets, a second home gets a lower one, and an investment property gets lower still.

Quorum's HELOC covers the home you live in and a second home. A one-unit second home reaches 90% CLTV with a 680 score and 80% from 640 to 679.

On the home you live in, a two-unit property reaches 90% with a 680 score, and a three- or four-unit property reaches 75%.

For an investment property, Quorum's guideline sheet of the same date lists a separate investment HELOC that stops at 80% CLTV.

Angel Oak puts a second home and an investment property on the same rows. Its home equity line reaches 80% CLTV with a 720 score and 75% with a 700 on either one.

For a Luxury cash-out second mortgage, the home you live in gets the highest maximum CLTV and an investment property the lowest, as the table shows.

Luxury cash-out second mortgage	Home you live in	Second home	Investment property
740 score	85%	80%	70%
680 score	70%	65%	60%

Loan size and the maximum CLTV

The larger the second mortgage, the lower the maximum CLTV, and each guideline sheet pairs its maximum CLTV with a largest loan. Quorum's pairings, with the largest line for each, are in the table below.

Credit score	Maximum CLTV	Largest line
720 and up	under 65%	$750,000
720 and up	up to 95%	$500,000
680 to 719	under 65%	$750,000
680 to 719	up to 90%	$500,000
660 to 679	under 80%	$200,000

Angel Oak allows its $750,000 HELOC only at 75% CLTV with a 720 score, and its 90% line stops at $500,000.

Luxury allows 85% CLTV up to a $500,000 second mortgage and 75% up to $1,000,000, at a 740 score on the home you live in. Its guidelines also cap the first and second mortgage together at $2,000,000 when the CLTV is over 80%.

Your borrowing amount compared with your equity

In the example above, the lender counts 85% of the home's value, $382,500, and not the full $450,000. That is why the most you can borrow, $92,500, is smaller than your $160,000 in equity. A second mortgage is paid after the first if the home is ever sold to settle the debts, and the cushion protects the lender. Second mortgages and HELOCs explained covers why that position is priced the way it is.

Several things on the guideline sheets shrink the amount further. If the appraisal shows home values falling in your area, Quorum lowers its maximum CLTV, down to 65% when values have fallen more than 10%.

Quorum also sets the maximum CLTV at 65% when the valuation gives no percentage for the market at all. On a two- to four-unit home or a second home, any declining market sets it at 65%.

Quorum limits a home listed for sale in the last six months to 80% once the listing is removed, and Angel Oak's sheet does not accept a recently listed home at all.

A higher CLTV also means a fuller valuation. Angel Oak requires a full appraisal on any home equity line or closed-end second mortgage above 80% CLTV. Luxury's guidelines require a CDA, an added review of the appraisal, whenever the CLTV is over 80%. Luxury also applies a 5% reduction to its CLTV matrix on an interest-only second mortgage, one where you pay only interest for a set period.

Finding your own CLTV before we talk

You can divide your balance by the value to get your CLTV today, then multiply the value by the maximum CLTV you expect and subtract your balance to see how much you could borrow. A recent sale on your street is a fine starting point for the value, though the lender's valuation is the one that counts.

When you're ready, please provide your most recent monthly mortgage statement, all pages. The balance on it is your first mortgage, and the rate on it helps us see whether a second mortgage or a cash-out refinance fits you better. Please also tell me the credit limit of any line you already have on the home, your credit score, and how you use the home.

Your next step

You are welcome to call me at (843) 765-0000 or email jeff@solverya.com with your first mortgage balance, a value you think is close, the credit limit on any line you already have, and roughly where your credit score is. I will run the formula against each of the guideline sheets above, tell you which row your file lands on, and quote the second mortgage to you directly from the lender's current guidelines. Quorum's HELOC is not offered in Texas and Angel Oak does not offer its owner-occupied program there, so I also confirm who can lend where your home is.

If you are weighing a cash-out refinance against adding a second mortgage, Rate & Best Fit prices that first mortgage scenario on your own time. It does not price a second mortgage or a line. You can choose a rate option that works best for you, and that selection can change later.

Common questions

What does CLTV stand for on a HELOC?

CLTV stands for combined loan-to-value. On a home equity line it is the total of every mortgage on the home, your first mortgage balance plus the full credit limit of the line, divided by the home's value. Luxury Mortgage's Simple Seconds guidelines dated May 12, 2026 count a line's credit limit regardless of the amount drawn.

Is CLTV the same as LTV?

Loan-to-value divides one loan by the home's value. Combined loan-to-value divides the total of all liens on the home, the first mortgage plus any second mortgage or line of credit, by that value, because the first mortgage is still there in front of the second.

Does a HELOC count at its full credit limit or only what I draw?

Under Luxury Mortgage's Simple Seconds guidelines dated May 12, 2026, the full credit limit counts in the combined loan-to-value calculation regardless of the amount drawn. That applies to a new line being sized and to an existing line on the same home, so a line with nothing drawn on it still adds its whole limit to the total of all liens.

What is the maximum CLTV for a HELOC?

It depends on the lender's guideline sheet and your row on it. Quorum's guideline sheet dated May 1, 2026 reaches 95 percent on a one-unit home you live in with a credit score of 720 or higher, 90 percent from 680 to 719 and 80 percent from 640 to 679. Angel Oak's guideline sheet dated May 8, 2026 reaches 90 percent on its HELOC with a 760 score, 85 percent at 720 and 75 percent at 680.

A second home, an investment property or a larger line lowers the maximum on both guideline sheets.

How do I figure out how much I can borrow from my CLTV?

Multiply the home's value by the maximum CLTV for your row, then subtract your first mortgage balance and the credit limit of any line already on the home. The remainder is the most the new second mortgage or line can be under that row.
