The Quick Read: You qualify in two stages: first the lender classifies your second home and approves a line against its equity, then a separate loan approves the rental you want to buy with that money. The classification of the second home sets the leverage, the credit score and the line size you can reach.
- A true second home can reach 90% combined loan-to-value (CLTV) on the Lendmire network, but only with a credit profile of 720 or better. The floor on a second-home line is 640.
- If the home is rented out, it is reviewed as an investment property. That caps the line at 70% CLTV and $500,000, with a 700 credit floor.
- The line must sit in your own name or a revocable living trust. An LLC cannot hold title on these lines.
- The rental you buy with the money is a second file. It is usually a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Which Property Are You Actually Borrowing Against?
The title mixes two ideas, and the lender separates them on day one. One is the collateral, which is the second home you own. The other is the purpose, which is funding an investment property. A line secured by your second home is priced as a second-home line, not as an investment line, as long as the home is truly used personally.
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.
Lenders sort every property into primary residence, second home or investment property. That label drives everything else. Across the wholesale network Lendmire works with, the label changes the maximum CLTV, the minimum credit score and the draw structure.
Here is how the three look side by side on the lines Lendmire brokers, subject to lender guidelines and full file review.
| Factor | Second home | Investment property |
|---|---|---|
| Max CLTV | Up to 90% (720+ only) | 70% |
| Credit floor | 640 | 700 |
| Max line | Up to $500,000 | $500,000 |
| Draw structure | 3-yr or 5-yr draw | 5-yr draw, 25-yr repay |
A line above $500,000 exists only on primary residences, so neither of these categories reaches it. The 90% figure never applies without the 720 score attached. A borrower at 640 sits in a lower CLTV tier, and the exact step-down varies by program.
How Does the Lender Decide It Is Really a Second Home?
Lenders look at how the property is used, not what you call it. A home you occupy yourself for part of the year, and do not rent out, reads as a second home. Regular rental use can move it into the investment column.
NerdWallet discusses how a property’s use can affect whether it counts as a second home or an investment property. Tax definitions of that use may differ from a lender’s own definition. Treat the guidance as a hint, not a safe harbor.
The decision runs in roughly this order:
1. Do you use the home personally, and is that documented by your own occupancy statements?
2. Is it listed on a rental platform or leased out under a lease?
3. Does the file show rental income from it?
4. Does the overall arrangement look like a business or a personal retreat?
Misstating occupancy is the fastest way to lose a file. If the home does produce rent, apply as an investment property from the start. You get a lower ceiling, but the file is clean.
Rental use matters for another reason. The CFPB’s HELOC booklet warns that a line’s terms may prohibit renting out the home that secures it. Read your line agreement before you list the property.
Stage One: What the Line Itself Requires
The line is a standalone second-lien or first-lien product, so an existing first mortgage does not block it. The lender adds your first mortgage and the new line, then divides by the appraised value. That is your CLTV.
Here are the main checks.
Credit. A second-home line floors at 640, and 720 or better is needed to reach the top CLTV tier. The lender uses a single-bureau score tied to the primary wage earner. The report must be no more than 90 days old at closing, and there are no rescores. Tradeline and housing-history standards differ by program. Housing history is applied across all financed properties, so a late payment on a different property still counts.
Debt-to-income. The ceiling is 50%, dropping to 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Plan for that stricter test.
Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you can ask for a full appraisal in any case.
Title. Fee simple or leasehold title held by you individually or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. If your second home sits in an LLC, you need a vesting change before applying.
Property type. Single-family, 2-4 units, PUD, townhome and condominium (including non-warrantable) all work. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not eligible.
Exposure. A borrower may hold three lines at most, and a borrower with more than 15 financed properties is not eligible. If you already own a stack of rentals, check that count first.
Location. Lendmire’s HELOC availability covers its 16 full-service states only: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. That is narrower than its DSCR footprint. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX and WA. New Mexico and Ohio set a CLTV cap that depends on credit. Texas second homes and investment properties are treated as non-homestead transactions.
How the Line Behaves After Closing
Plan for a variable structure. A line is an open-end credit, which means you borrow, repay and borrow again within the limit. The CFPB describes a draw period followed by a repayment period.
On a second home, the network offers a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Tennessee shortens both. Pricing floats through the draw and the repayment and never converts to fixed. At least 75% of the line is drawn at closing. After that, the minimum draw is $1,000, with Texas at $4,000, on the longer-runway structure.
That 75% draw rule shapes the strategy. You cannot open a large line and leave it idle as a safety net. You will carry the payment from day one, so size the line to what the purchase needs.
Stage Two: Qualifying for the Rental You Are Buying
The line only supplies money. The investment property is its own file, and you will typically finance it with a DSCR loan. The complete DSCR loans guide covers the full mechanics.
Across the wholesale network, purchase leverage mostly lands at 75% to 80% LTV, which means a 20% to 25% down payment. Select programs reach 85% LTV with roughly a 700-plus score. Credit floors start at 620 in parts of the network, and most programs want around 660. Coverage of 1.00 is where select programs start, not a universal standard. A separate select-lender path goes below 1.00 with leverage and terms adjusted. Reserves commonly run around 6 months of PITIA (principal, interest, taxes, insurance and association dues), though they vary by lender, leverage and loan size.
Here is where your line collides with the purchase loan. The DSCR lender reviews where your down payment and reserves came from. Money borrowed against another property is a documented source, but some lenders treat borrowed funds differently from cash in the bank. Disclose the line early and ask how each lender counts it. Reserves held in the drawn balance may not count the way savings do.
One contrast is worth knowing. The DSCR purchase can sometimes be titled in an LLC, subject to lender program eligibility. The HELOC on your second home cannot. Different loans, different vesting rules.
A Worked Example (Percentages and Ratios Only)
Say you own a lake cabin that you use personally and do not rent out. Its first mortgage balance is about 50% of the home’s value. You have a 740 credit score and a DTI well under 45%. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
- The network’s second-home ceiling for your score is 90% CLTV.
- A line that brings your total debt to roughly 70% CLTV is a cautious draw, leaving 20 points of cushion below the ceiling.
- You use that money for the down payment on a duplex, financed at 75% LTV through a DSCR loan.
- The duplex’s rent covers its full monthly obligation at roughly 1.2x. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The numbers clear both tests: enough equity on the cabin and enough rental coverage on the duplex. Now change one fact. If you rented the cabin on a lease, it would be reviewed as an investment property. The ceiling falls to 70% CLTV and the credit floor rises to 700. In this example you would have much less room to draw.
One caution on that 1.2x. DSCR compares rent to PITIA only. Clearing it does not mean positive cash flow, because repairs, vacancy, management, utilities and capex sit outside the calculation. You will carry the line payment on top of the duplex’s costs.
Which Property Should Be the Collateral?
You have three possible collateral choices. Weigh them honestly.
| Collateral | Typical strength | Typical drawback |
|---|---|---|
| Second home | Higher CLTV ceiling (720+) | Rental use risk |
| Primary residence | Higher ceilings, larger lines | Puts your home at risk |
| Target rental itself | Keeps other homes clear | 70% CLTV, 700 floor, $500K cap |
The second home often has the better ceiling than an investment line. The tradeoff is a personal-use requirement that you must keep honoring. Market surveys report that investment-property lines typically want a 720 score (NerdWallet) and cap CLTV at around 80% (Experian). On the Lendmire network, an investment line floors at 700 and caps at 70% CLTV. The higher market ceiling is not available here.
Because an investment line never exceeds $500,000, it falls in the automated-valuation lane and commonly closes with no traditional appraisal. That is convenient, but not a reason to put a rental on the hook if a second home has the equity.
When This Strategy Is the Wrong Tool
Skip it if you plan to hold the rental for decades on thin coverage. A floating payment on top of a DSCR payment can squeeze a rental that barely clears coverage. A DSCR cash-out refinance on an existing rental, with typical seasoning of about 6 months and a ceiling around 75% LTV on standard rentals, may fit better. Details sit in Lendmire’s guide to cash-out refinancing an investment property. Also pause if your second home is in an LLC, if it is on the ineligible property list, or if you lose sleep over variable payments. Falling behind can put the pledged home at risk of foreclosure. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Existing liens matter too. Lendmire’s piece How to Qualify for an Investment Property HELOC With an Existing Second Lien on Your Home explains how a line interacts with a loan already in second position.
Pre-Application Self-Check
Run this list before you apply:
- Credit score: 640 or better for a second home, 720 or better for the top tier.
- Title: your name or a revocable trust, not an LLC.
- Use: personal, with no lease or rental listing on the home.
- Property: not a manufactured home, co-op, condotel or log home.
- Debt-to-income: under 45% if your score sits under 680.
- Location: one of the 16 states, and not recently listed for sale where that bars eligibility.
- Existing lines: fewer than three, and no more than 15 financed properties.
- Purchase file: a rental with coverage that works at your planned leverage.
Key Terms Defined
Combined loan-to-value (CLTV): your first mortgage plus the new line, divided by the home’s appraised value.
Second home: a home you use personally for part of the year and do not rent out.
Draw period: the stretch when you can borrow from the line, usually with interest-only payments.
DSCR: the ratio of a rental’s income to its full monthly housing payment, used to qualify a rental purchase.
PITIA: principal, interest, taxes, insurance and association dues, the full monthly housing obligation.
Frequently Asked Questions
Can I use a line on my second home for a rental purchase down payment?
Often, yes, if the lender approves the line and your purchase lender accepts the source of funds. Disclose the line early. Eligibility depends on your credit, the home’s use and the loan program. This is not a commitment to lend.
What happens if I start renting the second home after I get the line?
The home can be reclassified as an investment property in the lender’s eyes. Your line agreement may also restrict rental use. Talk to the servicer before listing the property.
Can an LLC own the second home that secures the line?
No. These lines require the individual borrower or a revocable living trust to hold title. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance may fit better.
Does the line payment count against me on the rental loan?
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lenders still review your overall obligations and reserves. Ask each lender how it treats a drawn line.
How much can I borrow?
Second-home and investment lines on the Lendmire network top out at $500,000, with a $25,000 minimum (Michigan $10,000). Your CLTV ceiling and credit tier usually bind first.
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. Lendmire brokers through select wholesale partners and is not the lender, and the 16-state HELOC footprint is narrower than its DSCR coverage of 41 markets, including Washington, D.C.
