What HCLTV and HTLTV mean
HCLTV (home equity combined loan-to-value) is your first mortgage plus the full credit limit of any HELOC, plus the balance of any other second mortgage, divided by your home’s value. HTLTV is Freddie Mac’s name for the same ratio. Because both count undrawn credit, HCLTV can decide whether a refinance that keeps a HELOC is eligible.
Each agency also writes the rule in its own guide:
- HCLTV (Fannie Mae): the sum of “the original loan amount of the first mortgage, the full amount of any HELOCs (whether or not funds have been drawn), and the unpaid principal balance (UPB) of all closed-end subordinate financing,” divided by the property value (Selling Guide B2-1.2-03).
- HTLTV (Freddie Mac): “Divide the sum of the First Lien Mortgage amount and the total HELOC credit line limit and any other secondary financing by the ‘value'” (Seller/Servicer Guide 4203.1). Freddie Mac spells it out as “Home Equity Line of Credit (HELOC) TLTV.”
The formula: HCLTV = (first mortgage + full HELOC credit limit + other second mortgage balances) ÷ home value × 100
On a refinance, “value” generally means the appraised value. On a purchase, however, both agencies use the lower of the sales price or the appraised value.
You may also see HLTV. It is lender shorthand, not a defined term in Fannie Mae’s HCLTV section or Freddie Mac’s Section 4203.1, so ask what it counts.
LTV, CLTV, TLTV, HCLTV and HTLTV compared
These ratios share one denominator, your home’s value. In other words, they differ only in which debts go on top.
| Term | Stands for | What it counts | Who uses it |
|---|---|---|---|
| LTV | Loan-to-value | First mortgage only | Every loan program |
| CLTV | Combined loan-to-value | First mortgage + drawn HELOC balance + other second mortgage balances | Fannie Mae (B2-1.2-02) |
| TLTV | Total loan-to-value | First mortgage + disbursed amount of all secondary financing, HELOCs included | Freddie Mac (4203.1) |
| HCLTV | Home equity combined loan-to-value | First mortgage + full HELOC credit limit + other second mortgage balances | Fannie Mae (B2-1.2-03) |
| HTLTV | HELOC total loan-to-value | First mortgage + total HELOC credit line + other secondary financing | Freddie Mac (4203.1) |
So Fannie Mae’s CLTV and Freddie Mac’s TLTV are the counterpart ratios that count only drawn amounts, and HCLTV and HTLTV are the counterpart ratios that count the full HELOC line.
FHA does not use TLTV, HCLTV or HTLTV. Instead, HUD Handbook 4000.1 uses CLTV, and for a rate-and-term refinance it says the lender “must utilize the maximum accessible credit limit” of a HELOC (4000.1 Update 18, II.A.8.d.vi(A)(2)(c)). In practice, then, an FHA CLTV on a rate-and-term refinance works like an HCLTV. VA’s refinance chapter (Pamphlet 26-7, chapter 6) sets no combined ratio of this kind. However, it requires other lien holders to subordinate to the new VA loan.
How to calculate HCLTV: a worked example
For example, say a hypothetical home appraises at $400,000. The owner is refinancing into a new $280,000 first mortgage and taking no cash out. They also have a $50,000 HELOC with $15,000 drawn.
| Step | Ratio | Math | Result |
|---|---|---|---|
| 1 | LTV | $280,000 ÷ $400,000 | 70% |
| 2 | CLTV (Fannie) / TLTV (Freddie) | ($280,000 + $15,000) ÷ $400,000 | 73.75% |
| 3 | HCLTV (Fannie) / HTLTV (Freddie) | ($280,000 + $50,000) ÷ $400,000 | 82.5% |
So the $35,000 of unused credit adds 8.75 percentage points to the HCLTV.
Both agencies also round up. Fannie Mae truncates each ratio to two decimal places and then rounds up to the nearest whole percent (B2-1.2-01), and the same rule covers CLTV and HCLTV. Freddie Mac says the calculated ratio “must be rounded up to the next whole number.” Under either rule, this example’s CLTV (or TLTV) is 74% and its HCLTV (or HTLTV) is 83%.
A HELOC is one type of second mortgage. By contrast, a closed-end home equity loan counts at its unpaid balance in all of these ratios.
Why HCLTV matters when you refinance
Lenders check the highest of your LTV, CLTV and HCLTV against the program limit. Your HELOC can therefore block a refinance even when your first mortgage alone fits easily.
Eligibility limits
Fannie Mae’s Eligibility Matrix (Desktop Underwriter version 12.1, as read on 2026-11-11) lists one maximum for “LTV, CLTV, HCLTV” on each loan type. For a one-unit principal residence:
| Refinance type | Fannie Mae max LTV/CLTV/HCLTV (DU loans) | Freddie Mac max LTV/TLTV/HTLTV |
|---|---|---|
| Limited cash-out (no cash-out) refinance | 97% fixed rate, 95% ARM | 95% |
| Cash-out refinance | 80% | 80% |
On a standard Desktop Underwriter loan, Fannie Mae allows more than 95% on a limited cash-out refinance only for a fixed-rate loan on a one-unit principal residence, and only when Fannie Mae already owns the existing mortgage (B2-1.3-02). Freddie Mac’s 95% figure is for Loan Product Advisor Accept loans that are not super conforming; its 80% cash-out figure also covers super conforming loans. A lender can also set a lower limit of its own, called an overlay.
In the example above, an HCLTV of 82.5% fits under both no-cash-out limits. Now say the same owner wants a cash-out refinance instead, raising the first mortgage to $300,000 and keeping the HELOC open:
- LTV: $300,000 ÷ $400,000 = 75%
- CLTV: ($300,000 + $15,000) ÷ $400,000 = 78.75%
- HCLTV: ($300,000 + $50,000) ÷ $400,000 = 87.5%
The first two ratios pass the 80% cash-out limit. The HCLTV does not, so the loan as structured would not be eligible for sale to Fannie Mae.
Pricing
Fannie Mae charges a loan-level price adjustment (LLPA) for subordinate financing on a limited cash-out refinance. According to the matrix footnote, it applies when the CLTV is greater than the LTV, and “the undrawn portion of a HELOC is not included in CLTV.” For an LTV between 60.01% and 70%, the matrix lists 0.625%, calculated on the loan’s principal balance when Fannie Mae acquires it.
In the example, the $15,000 drawn balance pushes the CLTV above the LTV. As a result, the adjustment would be 0.625% of $280,000, or $1,750. How a lender passes it on (rate or points) varies. Note that this charge follows the drawn balance, while eligibility follows the full line.
Subordination
If you refinance the first mortgage and keep the HELOC, the HELOC lender has to agree to stay in second place. Fannie Mae “requires execution and recordation of a resubordination agreement” unless state law keeps the lien in its old position (B2-1.2-04). Likewise, VA and FHA Streamline refinances require existing second liens to subordinate. The HELOC lender decides whether to sign, and some charge a fee or take time to process the request, so ask early. Learn more about FHA Streamline refinancing with a second mortgage.
If your HCLTV is too high: options
Ask for a permanent credit limit reduction. Fannie Mae uses the reduced limit in the HCLTV if the HELOC “has been permanently modified” and the lender documents it. In the cash-out example, cutting the line to $20,000 brings the HCLTV to exactly 80%: ($300,000 + $20,000) ÷ $400,000. If your balance is higher than the new limit, though, the lender uses the balance.
Pay down the balance, then lower the limit. Paying first lets you cut the line further, so your CLTV and HCLTV fall together.
Pay off and close the HELOC. With no second lien, all three ratios equal your LTV. However, Fannie Mae treats paying off a second mortgage that was not used to buy the home as a cash-out refinance, with the 80% limit, even if you take no cash. If you plan to pay the HELOC off before you refinance, ask the lender how it will classify the loan.
Lock the line or convert it. Some HELOC lenders can freeze draws or move the balance to a fixed-rate loan. Get it in writing, because the refinance lender needs proof the change is permanent. Read how a home equity line of credit works, and compare HELOC vs. home equity loan terms.
Look at another loan program. An FHA rate-and-term refinance allows a CLTV up to 97.75%, counting the full line. Meanwhile, an FHA Streamline has “no maximum CLTV,” although it only refinances an existing FHA loan. See more high-LTV refinance options.
Once your HCLTV fits, compare quotes from lenders that handle refinances with a HELOC in place.
HCLTV FAQ
What does HCLTV mean in a mortgage?
HCLTV stands for home equity combined loan-to-value. It is Fannie Mae’s ratio of your first mortgage plus your full HELOC credit limit and other second mortgage balances, divided by your home’s value.
Is HTLTV the same as HCLTV?
Yes, the math is the same. HTLTV is Freddie Mac’s term and HCLTV is Fannie Mae’s, and both count the whole HELOC credit line. Both agencies also round the result up to the next whole number before comparing it with a limit.
What is HLTV in a mortgage?
HLTV is shorthand some lenders use for a HELOC-inclusive loan-to-value ratio. Neither Fannie Mae’s HCLTV section nor Freddie Mac’s Section 4203.1 defines it. If a lender quotes an HLTV, ask whether it counts your full credit line.
What does TLTV mean, and how is it different from CLTV?
TLTV means total loan-to-value. It is Freddie Mac’s ratio of the first mortgage plus the drawn amount of all second mortgages, HELOCs included. Fannie Mae’s counterpart is CLTV. Neither counts unused HELOC credit.
Know your HCLTV before you apply
Pull your latest HELOC statement, add the full credit limit to your expected first mortgage, and divide by a realistic home value. If the result is near the limit for your refinance, talk to your HELOC lender about the credit limit before you apply.
