The Quick Read: It depends on whether you want to keep your existing first mortgage and how you plan to use the money: a HELOC typically adds a second lien and leaves the first mortgage alone, a cash-out refinance replaces it with one larger loan, and on a second home the lender’s occupancy rules can decide the question before preference does. Both tools are priced and underwritten differently on a second home than on a primary residence. Both hinge on how the property is classified.
- A HELOC leaves your first mortgage untouched. A cash-out refinance replaces it.
- On the Lendmire network, second-home lines start at a 640 credit score. The 90% combined LTV ceiling needs a 720 score or better.
- Investment-property lines top out at 70% combined LTV. A genuine second home cannot go into a DSCR loan until it is reclassified as a rental.
- HELOC pricing floats and never converts to fixed. Cash-out refinance terms are set once.
- Qualification on both depends on lender guidelines, credit approval, and property review.
What Each Option Does
A HELOC is a line of credit secured by the property, sitting behind or beside your existing financing. A cash-out refinance is a new first mortgage that pays off the old one and hands you the difference.
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.
That structural gap drives almost every other difference. With a HELOC, you carry two obligations and the first mortgage stays exactly as it is. With a cash-out refinance, you carry one new loan, and whatever terms you had on the old loan are gone.
On the wholesale network Lendmire works with, the HELOC product is a standalone line. It can sit in first or second lien position. Most borrowers will use it as a second lien behind an existing first mortgage. Lendmire is a broker. It arranges these lines through select wholesale partners and does not lend.
How a Second Home Changes the Equation
A second home is a property you use yourself. That one fact changes which products are open to you, which lenders will say yes, and how the file is underwritten.
Lenders sort properties into three buckets: primary residence, second home, and investment property. The bucket sets the leverage ceiling, the credit floor, and the documents you provide. Many borrowers assume a vacation property gets primary-residence treatment. It doesn’t.
Here is how the network’s HELOC program treats a second home. These figures reflect select wholesale-network guidelines and are subject to lender review.
- Minimum credit score is 640.
- Combined LTV (CLTV, meaning your first mortgage plus the new line against the home’s value) scales with credit. A 640 profile reaches 75% CLTV, 660 reaches 80%, 680 and 700 reach 85%, and 720 or better reaches 90%.
- Second-home lines cap at $500,000.
- Title must sit with an individual or a revocable living trust. An LLC cannot hold it.
- Debt-to-income runs to 50% at most. It drops to 45% for credit profiles from 600 to 679, and a ratio above 45% needs a 680 score.
An investment property gets tighter treatment. The ceiling is 70% CLTV, the minimum score is 700, and the line caps at $500,000. Investment lines run a single draw structure.
The line is also not a free-roaming credit card. At least 75% of it is drawn at closing. Treat it as a mostly funded second loan with a small reserve of access behind it.
Side-by-Side: Cash-Out Refinance vs. HELOC
| Factor | Cash-out refinance | HELOC (network line) |
|---|---|---|
| Structure | New first mortgage replaces old | Standalone line, first or second lien |
| Existing first mortgage | Paid off | Stays in place |
| Funds | One lump sum | At least 75% drawn at closing |
| Pricing behavior | Set once for the loan | Floats; never converts to fixed |
| Qualification (second home) | Borrower income and credit | Credit, DTI, and equity |
| Main drawback | Gives up your current terms | Payments change; two loans |
The Pivotal Question: Keep or Replace the First Mortgage?
Start here. If your existing first mortgage has terms you would not match today, a HELOC lets you keep it. If those terms are no better than what a new first mortgage would carry, replacing it costs you little and simplifies the file.
The honest way to compare is blended cost. Add up what you would carry on the existing first mortgage plus the new line, and compare that against a single new first mortgage. Run it both ways. A line behind a good first mortgage can come out ahead even when the line itself looks expensive. A cash-out refinance can win when the first mortgage is nothing special.
Closing costs also differ. A new first mortgage usually carries heavier closing costs than a line. Price that in before deciding.
This is a decision for your own numbers, not a rule of thumb. Keep the existing first mortgage when its terms are worth protecting. Replace it when they aren’t.
A Worked Example
Run the numbers on a second home with an existing first mortgage equal to about 55% of its value. The borrower holds a 720 credit score. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
At 720, the second-home table allows up to 90% CLTV, subject to the $500,000 line cap. That leaves room of up to roughly 35% of the home’s value in combined equity access, before the line cap is applied.
Drop the score to 680 and the ceiling falls to 85% CLTV. Room shrinks to about 30% of value. Drop to 640 and the ceiling is 75% CLTV, leaving about 20%.
Same house, same first mortgage, three very different lines. Credit does as much work as equity here.
Now flip it to an investment property with the same first mortgage. The ceiling is 70% CLTV at a 700 minimum. Room tops out near 15% of value, however strong the credit.
That is the math. A second-home file can stall when the borrower sizes the line to the primary-residence tier.
Choose a HELOC If…
- Your first mortgage has terms you want to keep.
- You hold a 640 or higher score, and ideally 720 for the top leverage tier.
- The property is a genuine second home or sits in a revocable trust.
- Your DTI sits at or below 50%, with a 680 score if it runs above 45%.
- You are comfortable with payments that can change over time.
- The property is in one of the 16 states where Lendmire arranges these lines: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.
Choose a Cash-Out Refinance If…
- Your first mortgage carries no terms worth protecting.
- You need a single lump sum for a known, large use.
- You want one payment and one lien instead of two.
- You want a fixed structure, not a line that floats.
- You need to exceed line limits. A line above $500,000 is available only on a primary residence.
- The property is deeded to an LLC and you don’t want to move title. A DSCR cash-out is the path in that case.
When a DSCR Loan Enters the Picture
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It is built for non-owner-occupied investment properties. Because these are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
That is why a genuine second home cannot go straight into one. You use a second home yourself. A DSCR file treats the property as a rental. You cannot be the borrower-occupant and the landlord on the same file.
So the real question is whether you want to change the property’s classification.
- Keep it a second home. Use a HELOC or a conventional-style cash-out refinance. A bank-statement path can sometimes finance a genuine second home on documented income under the applicable program, subject to lender guidelines, without forcing a rental conversion.
- Convert it to a rental. Refinance it as non-owner-occupied under a DSCR program, or place the line against it as an investment property. That puts it on rental-coverage rules, and on a different leverage table.
Once converted, the numbers shift. Across the wholesale network, standard rentals on a DSCR cash-out refinance top out around 75% LTV, with about 6 months of seasoning as the common expectation. Short-term rental collateral on a cash-out refinance tops out at 70% LTV. Short-term rental programs typically want a 640 or better score and about 12 months of hosting history. 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.
Coverage matters most after conversion. A DSCR compares rent to PITIA only, meaning principal, interest, taxes, insurance, and association dues. A 1.00 ratio is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better leverage.
Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation. Plan for them separately.
On a conversion, DSCR often binds before equity does. You can have plenty of equity and still fall short because the new, larger payment is tested against rent. If the borrower holds title in an LLC, DSCR files are available subject to program terms. HELOC title cannot sit in one.
Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months.
Credit also matters on this side of the fence. A 620 floor exists in parts of the network. Most programs want around 660. A 700 or better score unlocks the strongest tiers. The complete DSCR loans guide covers the full set of program mechanics.
Risks and Downside Scenarios
HELOC payment changes. The CFPB’s explainer on home equity lines says these lines usually carry variable pricing, so payments can change from month to month. It also describes a draw period that could last 10 years, as an example. On the network’s lines, pricing floats across both the draw and the repayment period.
Payment shock at conversion. The CFPB’s HELOC brochure notes some plans are interest-only during the draw period. The network’s lines work the same way. One structure runs a 3-year interest-only draw followed by 17 years of full repayment. The other runs a 5-year draw followed by 25 years. When the draw ends, the payment steps up. Qualification itself is calculated on the interest-only payment at the maximum draw, so the test already assumes a full line.
Two obligations. A line behind a first mortgage means two payments, and both count toward DTI. A borrower with several mortgages can hit the 50% ceiling sooner than expected.
Exposure limits. A borrower is limited to three lines. A borrower owning more than 15 financed properties is not eligible. Combined exposure caps at $2,000,000 on one wholesale program and $750,000 on the other.
Value risk. If values drop, a line sized at high CLTV leaves little cushion. A cash-out refinance has the same exposure on one bigger loan.
Cash-out is not all cash. Payoff, closing costs, reserves, and any prepayment charge come out first.
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.
Common Mistakes on Second-Home Equity Files
1. Assuming any lender offers a second-home line. Availability is lender-specific. Some lenders skip second homes entirely.
2. Applying primary-residence leverage. The 90% CLTV tier is tied to second homes at a 720 or better score. It is not a general ceiling.
3. Holding title in an LLC. A property deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
4. Ignoring property type. Manufactured homes, co-ops, condotels, log homes, and agricultural or mixed-use zoning are not eligible. Condos, including non-warrantable ones, townhomes, PUDs, and 2-4 unit properties can be.
5. Skipping the property listing check. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
6. Expecting an appraisal. Lines at or below $500,000 ordinarily run automated valuation, though a higher CLTV may require a secondary valuation. A borrower can request a full appraisal in any case. Above $500,000, a full appraisal is required.
A Practical Decision Process
1. Classify the property. Decide whether it is a genuine second home or a rental. Occupancy sets the whole table.
2. Pull your first-mortgage terms. Decide whether they are worth keeping.
3. Check your credit tier. The score sets your CLTV ceiling on a line and your leverage on a DSCR loan.
4. Check title. Individual or revocable trust for a line. An LLC points to DSCR.
5. Size the use of funds. A known lump sum favors a cash-out refinance. Staged or partial access favors a line.
6. Run the blended-cost comparison. Existing first plus new line, against one new first.
7. Test DTI and, if converting, DSCR coverage. Whichever test binds first sets your limit.
8. Gather documents. Entity or trust documents, a current mortgage statement, insurance, and for a conversion, lease evidence or hosting history. The credit report must be no more than 90 days old at closing.

Frequently Asked Questions
Can I get a HELOC on a second home?
Yes, through select lenders, though availability varies by lender. On the network Lendmire works with, second-home lines start at a 640 score and reach 90% CLTV only at 720 or better. Lines cap at $500,000, and title must be held by an individual or a revocable trust. The line must be in one of 16 full-service states.
Is it harder to qualify on a second home than a primary residence?
Yes, usually. Second homes floor at a 640 score on the network, with leverage that scales by credit tier. Investment properties are stricter still, at a 700 minimum and 70% CLTV. Qualification is always subject to lender guidelines and full file review.
Which is better if I plan to rent the property out?
Neither product treats a rental the way a DSCR loan does. Once the property is a rental, it is an investment property. A line against it caps at 70% CLTV. A DSCR cash-out refinance qualifies primarily on rental income covering the payment, with standard rentals topping out around 75% LTV and short-term rentals at 70% on a cash-out refinance. Which one fits depends on how much leverage you need and how strong the rent coverage is. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Can I use second-home equity to buy another property?
Yes, but how you do it matters. A line or cash-out refinance delivers the cash, and you then use it as a down payment. Keep in mind the equity comes with a payment on the second home, and the next lender may ask to see the funds. The DSCR test then applies to the new property, not the old one.
Can I put my second home into a DSCR loan?
Not while it stays a second home. A DSCR loan is business-purpose and non-owner-occupied. The property must be reclassified as a rental first. A bank-statement path can sometimes finance a genuine second home on documented income, subject to lender guidelines, with no occupancy change.
