The Quick Read: A vacation home line is limited by each lender’s combined loan-to-value ceiling for that type of occupancy, minus every lien already on the property, so the answer changes with the lender, your credit score, your lien position, and how you use the home. Across the wholesale network Lendmire works through, second-home lines reach 90% combined loan-to-value only at a 720 or better credit profile, with a $500,000 maximum line. Investment-property lines stop at 70%. Lendmire is a broker and never the lender, and every figure here is subject to lender guidelines and full file review.
- The limit is a percentage of the home’s value, not a percentage of your equity.
- The full credit line counts toward the ceiling, not just the amount you draw.
- Credit score steps the ceiling up or down on second-home lines.
- Renting the home out can change how a lender classifies it, and that changes the ceiling.
- A line is reviewed on your personal credit and debt-to-income ratio, not on rent coverage.
What Is a Vacation Home HELOC, and Who Sets the Limit?
A home equity line of credit (HELOC) is a revolving line secured by a property you own. You draw, repay, and draw again during a set period. On a vacation home, the lender takes that property as collateral and decides how much it will lend against it.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
No single industry maximum exists. Each lender sets its own ceiling, and many hold these lines in their own portfolio rather than selling them, which is why Opendoor’s explainer on borrowing against one home to buy another notes that cutoffs differ from one lender to the next. That is also why no honest table can list every lender’s limit side by side. Programs change, and each file is underwritten individually.
What a broker can do is compare how lenders behave in categories. That is the approach below.
How HELOC Equity Limits on a Vacation Home Are Calculated
The formula has three parts: value times the lender’s ceiling, minus every existing lien. The result is the largest line the lender will consider, before credit, debt-to-income, and dollar caps trim it further.
The ceiling is called combined loan-to-value (CLTV). It adds your first mortgage balance and the full requested line, then divides by the home’s value. Equity is simply value minus what you owe, as the CFPB’s HELOC overview defines it. Equity and borrowing room are different numbers, because the ceiling leaves a cushion untouched.
Here is the room under the ceiling, expressed as a share of the home’s value. Dollar conversion is left to you.
| First lien (% of value) | CLTV ceiling | Room for the line (% of value) |
|---|---|---|
| 0% (paid off) | 90% | 90% |
| 40% | 90% | 50% |
| 60% | 85% | 25% |
| 60% | 75% | 15% |
| 50% (investment) | 70% | 20% |
Two things shrink these results. A $500,000 dollar cap applies to second-home and investment lines on this network, so a valuable, mortgage-free home can hit the cap before it hits the percentage. And the full line counts, so a line you plan to draw only partly still uses up its entire share of the ceiling.
Which Ceiling Applies: Primary, Second Home, or Investment?
Occupancy sets the ceiling table. A lender first classifies the property as a primary residence, a second home, or an investment property. Each class gets a different maximum, and the investment class gets the lowest.
On the network, the ceilings run like this:
| Occupancy | Top CLTV ceiling | Condition |
|---|---|---|
| Primary residence | 90% | 720 or better credit profile |
| Second home | 90% | 720 or better credit profile |
| Investment property | 70% | Minimum 700 credit profile |
Market surveys report that home equity loans and HELOCs may allow borrowing up to 85% of a home’s value, according to Experian. That is a market-wide figure. On Lendmire’s network, the second-home ceiling is the tiered one shown in the next section, and 90% exists only at 720 or better.
The Second-Home Ceiling by Credit Tier
On second-home lines, your credit score decides the ceiling. Minimum credit is 640, and every tier carries the same $500,000 maximum line.
| Credit score | Max CLTV (second home) | Max line |
|---|---|---|
| 720+ | 90% | $500,000 |
| 700+ | 85% | $500,000 |
| 680+ | 85% | $500,000 |
| 660+ | 80% | $500,000 |
| 640+ | 75% | $500,000 |
A 660 borrower and a 720 borrower can own the identical home and see ceilings ten points apart. Where programs differ, each figure applies only inside its own program’s terms, which a loan officer confirms against the specific file.
How Underwriting Treats a Vacation Home Line, Step by Step
A vacation home line moves through the same sequence on most files. Knowing the order helps you spot where a limit gets cut.
1. Occupancy is classified. The lender decides whether the home is a second home or an investment property. This picks the ceiling table.
2. Credit is tiered. The score steps the ceiling up or down. The model is a single-bureau score keyed to the primary wage earner, and the report is generally no more than 90 days old at closing.
3. The home is valued. Lines at or below $500,000 ordinarily use an automated valuation model with no traditional appraisal. A higher CLTV may call for a secondary valuation. You may also request a full appraisal in any case.
4. Liens are counted. Every existing lien comes out of the ceiling, and the full line counts.
5. Income and debt are tested. The lender reviews your file on personal credit and debt-to-income (DTI), meaning your monthly debts as a share of your gross monthly income. The cap is 50%, or 45% for credit profiles from 600 to 679, and a ratio above 45% needs a 680 minimum. The test uses the interest-only payment calculated on the maximum draw.
6. The line is structured. At least 75% of the line is drawn at closing, a point many borrowers miss.
Notice what is absent: rent. A HELOC does not ask whether the vacation home’s rental income covers anything.
Draw and Repayment Structures
The line can sit in first or second lien position. If you hold a low-cost first mortgage, a second-lien line leaves it untouched. A cash-out refinance replaces it.
Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other has a 5-year draw followed by a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment structure only.
The line is variable on both structures and never converts to fixed, so payments can rise. The CFPB’s HELOC overview also warns that if you cannot repay, you could lose the property that secures the line. A minimum subsequent draw of $1,000 applies after closing on the 5-year structure.
How Limits Differ by Lender Type
Lenders fall into rough groups, and the group predicts your limit better than any single name.
Big banks and large retail lenders. Many offer lines only on an owner-occupied primary home. If they do lend on a second home, expect a lower ceiling than on a primary, and some add a dollar cap regardless of your equity. Jumbo-size lines often carry lower ceilings too.
Portfolio lenders and credit unions. These institutions hold the loan themselves, so their policies vary the most. Some are flexible on a second home, and some refuse it outright.
Specialty lenders in a wholesale network. This is where a broker adds value. Because a broker sees many lenders’ guidelines at once, a file that one lender declines can fit another’s tier. The tiers above come from that network.
NerdWallet’s guide to investment-property HELOCs notes that not every HELOC lender accepts investment properties, and that terms run stricter.
The HELOC product itself is available in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint.
Second Home or Investment Property? Where the Rule Breaks
The gap between a 90% ceiling and a 70% ceiling turns on classification. Several situations push a vacation home toward the lower class.
- Regular rental use. A home rented out heavily may be underwritten as an investment property. Any tax-reporting definition of personal use is a separate test from the lender’s occupancy rules. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
- Rental clauses in the line. The CFPB’s HELOC booklet warns that renting out your home may be prohibited under the terms of a line. Read that clause before you list the home.
- Title. The line must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A home already deeded to an LLC needs a vesting change, or a DSCR cash-out instead, subject to lender program eligibility.
- Property type. Single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
- Exposure. A borrower is limited to three lines in total, and anyone with more than 15 financed properties is not eligible.
- Listed for sale. In several states, a property listed for sale or listed within the past 60 days is ineligible.
A consistent pattern shows up on files like these. The borrower expects the 90% tier and discovers the lender reads the home as a rental. It is far cheaper to learn that before applying than after an appraisal order.
Equity in the Vacation Home or in Your Primary Home?
People searching this topic mean two different things. Some want a line against the vacation home. Others want a line against their primary home to buy or improve the vacation property.
Each route puts a different property at risk. A line on the vacation home pledges that property only. A line on your primary home pledges the place you live. The primary route can reach further, since lines above $500,000 are primary-residence only. Those lines cap at 75% CLTV and require a full appraisal, and credit must be 700 or better (720 on the longer-runway program).
For most investors, pledging the vacation home keeps the downside contained. Using the primary home gives bigger numbers, but the tradeoff is real.
Why Was My Limit Lower Than Expected?
A smaller-than-expected line usually traces to one of these causes:
- The ceiling applies to value, and the valuation came in below the price you paid.
- Seasonal or rural homes can confuse an automated valuation, and a full appraisal may read differently.
- The full line counted, not just the draw.
- Credit landed one tier lower than you assumed.
- The home was classified as an investment property.
- Debt-to-income, tested on the maximum draw, was the binding limit.
Some credit details also trip files. The history standards on tradelines and housing payments vary by program. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program, with one seasoning a foreclosure at 7 years and the other declining it entirely.
If a HELOC Isn’t Enough: The DSCR Alternative
A HELOC looks at you. A DSCR loan looks at the property. That difference matters when a vacation home earns real rent.
A DSCR (debt service coverage ratio) loan compares the property’s rent to its monthly payment covering principal, interest, taxes, insurance, and HOA dues, together called PITIA. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide covers that in full.
On the network, a DSCR cash-out refinance tops out around 75% LTV on standard rentals, and 70% on short-term-rental collateral. About 6 months of seasoning is the common expectation. Select programs start at 1.00 coverage, and a separate select-lender path goes below 1.00, with leverage and terms adjusted. Most programs want a score around 660, and 700 or better unlocks the strongest leverage.
Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
A DSCR loan also replaces your first mortgage rather than sitting beside it. If you want to keep a low-cost first lien, compare that tradeoff with Lendmire’s piece Rental HELOC vs Home HELOC Equity Limits With a Low First Lien. One more line on money: tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Can I get a HELOC on a vacation home at all?
Yes, through lenders that offer second-home lines, though many large banks do not. On Lendmire’s network, second-home lines run from 640 credit and up to a $500,000 maximum line, with the ceiling set by credit tier.
How much equity do I need left after the line?
At the top 720-plus tier on a second home, the ceiling leaves 10% of value untouched. At the 640 tier, it leaves 25%. Your existing mortgage and the full line both count toward that cushion.
Does renting the home out lower my limit?
Yes, it can. Regular rental use may cause a lender to classify the home as an investment property, where the ceiling is 70% instead of up to 90%. The line contract may also restrict rental use altogether.
Is the limit the same for a HELOC on an investment property?
No. Investment lines on the network cap at 70% CLTV, need a 700 credit profile, and run only the 5-year draw and 25-year repayment structure.
Can the HELOC fund the purchase of the vacation home?
A line on your primary home can fund a down payment, but it puts your primary home at risk. For a rental-oriented purchase, many investors compare that against a DSCR purchase loan, where leverage typically runs 75% to 80% LTV.
Next Step
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. The site calculator gives an illustrative estimate only. A vacation home that earns steady rent often deserves a DSCR comparison as well, since the two products measure different things.
