How Much Can You Borrow With a HELOC on a Second Home or Vacation Property?

The Quick Read: The line equals the home’s value times the lender’s maximum combined loan-to-value, minus every lien already on the property, and then it is capped at the program maximum. On the wholesale network Lendmire works with, a second-home line reaches 90% CLTV only at a 720+ credit profile, and the line tops out at $500,000.

• Second-home ceilings step down with credit: 90% at 720+, 85% at 700+ and 680+, 80% at 660+, 75% at 640+.
• Below those tiers, a second home is not eligible, because 640 is the credit floor.
• Renting the home out can reclassify it as an investment property, which caps the line at 70% CLTV with a 700 minimum credit score.
• The home must be titled to an individual or a revocable living trust. An LLC cannot hold title.
• A HELOC is not a DSCR loan. It is sized on equity and personal credit, not on rent.

Lendmire is a broker. It arranges these lines through select wholesale partners, and every figure below is subject to lender guidelines and full file review. Nothing here is a commitment to lend.

What Is the Borrowing Formula?

Value times the CLTV ceiling, minus existing liens, capped at the program maximum. That is the whole calculation. CLTV means every loan secured by the home, added together, divided by its value.

The federal consumer-finance regulator’s HELOC booklet describes the same logic: lenders take a percentage of the appraised value and subtract the mortgage balance. No federal rule sets that percentage for second homes. Each lender sets its own.

Run a modeled example. Assume a home valued at $400,000, a 75% ceiling, and a $150,000 first mortgage. Total debt allowed is $300,000. Subtract the $150,000 first mortgage and the room is $150,000. Those inputs are assumptions chosen for the math, not market data.

Now change one input. At a 720+ profile the ceiling on that same home moves to 90%. The room grows, but the $500,000 cap still sits on top. On a high-value home with a small mortgage, the cap binds before the equity math does.

How Does Credit Change the Ceiling?

On a second home, credit score moves the ceiling directly. Across the network, the tiers run like this:

Below 640, a second home is not eligible. The 90% figure exists only at 720 or better. Never read it as a general ceiling.

Opendoor’s explainer puts typical second-home and investment lines at 70–80% CLTV across the broader market. The network figures above are what apply to files placed through Lendmire’s wholesale partners.

Credit is also a personal-income test. Debt-to-income runs 50% maximum on the network, and a ratio above 45% needs a 680 score. The 45% limit for profiles from 600 to 679 applies to the network’s other occupancy types, since a second home starts at 640. The line is qualified on the interest-only payment calculated at the maximum draw, not the amount you plan to use. That catches borrowers who intend a small draw.

Which Property Type Are You, Really?

Classification decides the ceiling. A second home assumes you live in another home as your primary residence. A vacation home that earns rent can be treated as an investment property instead.

Investment lines top out at 70% CLTV, and they require a 700 minimum credit score. Unlike primary-residence and second-home lines, which offer a 3-year interest-only draw with a 17-year repayment or a 5-year interest-only draw with a 25-year repayment, investment lines run the 5-year interest-only draw with a 25-year repayment structure only.

Things that can trigger investment treatment: rental income on a tax return, regular bookings, or a management agreement. A borrower with no primary residence may also be reviewed as an investment property. Some line agreements restrict renting the collateral home outright, so read the agreement before listing the cabin.

Occupancy has to be stated honestly. A file that says second home and shows booking history is a file that gets re-papered.

Can an LLC Hold the Vacation Home?

No. Title must sit with the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines.

That is the sharpest structural difference from a DSCR loan. If the vacation home is already deeded to an LLC, there are two paths: change the vesting, or use a DSCR cash-out refinance instead, subject to program terms. Re-deeding can have its own consequences, so sort out the title question before anything else on the file.

What Else Limits the Line?

Beyond CLTV and credit, a handful of mechanical rules shape the number:

• Line size: $25,000 to $750,000 overall, but a second home caps at $500,000. Lines above $500,000 are primary-residence only.
• Valuation: lines at or below $500,000 ordinarily use an automated valuation rather than a traditional appraisal. A higher CLTV may require a secondary valuation, and a borrower can request a full appraisal in any case.
• Property type: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial or agricultural-zoned property are not.
• Exposure: a borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
• Structure: a standalone line in first or second lien position. Pricing floats and never converts to fixed. At least 75% of the line is drawn at closing.

Condotels matter for vacation buyers. A resort unit with hotel-style rental programs is often exactly what the network does not offer on this product.

Value can also move against you. The CFPB notes that if the home’s value drops significantly, the lender might not allow more credit. A line sized at peak value is not a guarantee of future access.

Collateral Choice: Vacation Home or Primary Home?

Many buyers ask the wrong question. The line does not have to sit on the vacation home. A line on your primary residence can fund a vacation purchase, because lenders look at the collateral, not the use of the funds.

The tradeoff is risk. Securing the line against your primary home puts the home you live in behind the second property. Securing it against the vacation home keeps the exposure on the asset it supports.

The numbers can differ too. Primary-residence lines can run above $500,000, up to $750,000, but only at a 700 or better credit profile (720 on the longer-runway structure), a 75% CLTV cap, and a full appraisal. Compare the two options on the same file, not by habit.

Where DSCR Fits (and Where It Doesn’t)

A HELOC and a DSCR loan answer different questions. The HELOC asks whether you, personally, can carry the debt and whether there is enough equity. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide covers the mechanics.

For a vacation home that is run as a rental, the decision often turns on a few points:

DSCR compares rent to PITIA only. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation. A cash-out refinance on a short-term rental typically tops out at 70% LTV, and expect a 640+ score and about 12 months of hosting history.

A second lien also eats into the equity a later cash-out could use. Stacking a line first can shrink a future DSCR cash-out. Lendmire’s piece How Much Can You Borrow on an Investment Property HELOC on a Vacation Home With High DTI? covers the debt-ratio side of this decision.

What Documents Does the File Need?

Expect a credit report no more than 90 days old at closing, proof of income, the property’s insurance and tax records, and a valuation. Credit runs on a single-bureau score keyed to the primary wage earner, with no rescores.

Housing history applies across all financed properties, not just the one being pledged. Derogatory events carry seasoning: a bankruptcy needs 4 years from discharge or dismissal. Foreclosure-family history varies by program, so a borrower with one on record needs the file matched to the right lender before anything is submitted.

Availability is narrower than most readers expect. Lendmire arranges these lines in 16 states, not across the whole DSCR footprint. Properties listed for sale, or listed within the past 60 days, are ineligible in several of them.

Texas has its own rules. Texas second homes and investment properties are eligible as non-homestead transactions, and Texas properties are limited to 10 acres.

Key Terms Defined

CLTV: combined loan-to-value, the total of all loans secured by the home divided by its value.

Equity: the home’s value minus what you owe on it.

Draw period: the stretch when you can borrow from the line, usually interest-only. The CFPB gives 10 years as an example, and the network’s structures run 3 or 5 years.

Occupancy type: how the lender classifies the home: primary residence, second home, or investment property.

PITIA: principal, interest, taxes, insurance, and association dues, the monthly obligation a DSCR compares rent against.
