The Quick Read: A HELOC is a revolving credit line secured by a home that runs in two phases: a draw period when you borrow and often pay only interest, then a repayment period when borrowing stops and the balance amortizes, so the monthly obligation steps up. Comparing offers on draw length, repayment length, how pricing floats, fees, and combined leverage matters more than any one feature. This guide walks through the mechanics, the terms worth lining up side by side, and the points where rental owners hit different rules.
- The line is sized by combined loan-to-value (CLTV), which counts your first mortgage and the new line together.
- Interest-only payments during the draw do not shrink the balance.
- The payment can jump when repayment starts, and some lines can require the full balance at once.
- Investment-property lines run on tighter rules than lines on a primary home, and fewer lenders offer them.
- Ownership matters: on the lines Lendmire arranges, an LLC cannot hold title.
Key Terms Defined
HELOC: a home equity line of credit, an open-ended line you can borrow against, repay, and borrow again up to a set limit.
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the home’s value.
Draw period: the window when you can borrow from the line, usually with interest-only payments.
Repayment period: the later phase when borrowing stops and the balance is paid down on a schedule.
Index: the published benchmark that a floating-price line follows up or down.
Margin: the fixed amount the lender adds on top of the index.
Cap: a limit on how far the line’s pricing can move in a set period or over the life of the line.
Lien position: whether the line sits first in line for repayment (first lien) or behind an existing mortgage (second lien).
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.
How Does a HELOC Work?
A HELOC works by turning home equity into a credit limit. The lender sets a maximum CLTV, subtracts what you still owe on the first mortgage, and sizes the line to what is left. You then draw as needed during the draw period.
Here is the equity test in plain percentages. Say a primary residence carries a first mortgage equal to 65% of its value. A borrower with a 720 or better credit profile sits under a ceiling that reaches 90% CLTV for lines up to $500,000, which leaves 25 points of value as room. On an investment property the ceiling is 70% CLTV, so a first mortgage at 60% leaves 10 points. Same equity, very different room.
The ceilings across Lendmire’s wholesale network depend on occupancy and credit. Everything below is subject to lender guidelines and full file review.
- Primary residence: the ceiling reaches 90% CLTV only at a 720 or better profile, for lines up to $500,000. At 700 or better the tier is 85% up to $500,000, and at 640 or better it is 80%.
- Second home: the ceiling reaches 90% CLTV at 720 or better, for lines up to $500,000, with a 640 credit minimum.
- Investment property: the ceiling is 70% CLTV for lines up to $500,000, with a 700 credit minimum.
A line above $500,000 is available on primary residences only. It caps at 75% CLTV and requires a full appraisal. The network also offers lines as small as $25,000.
What Happens in the Draw Period and the Repayment Period?
The draw period is the borrowing phase, and the repayment period is the paying-back phase. Payments usually rise at the switch, because principal joins the payment. Many borrowers plan for the draw and underestimate the second phase.
Market surveys report that a draw period typically lasts five to 10 years, followed by a 20-year repayment period, and that some lines carry a balloon payment when the draw ends, according to Experian. The same source notes that you may be expected to pay only accrued interest during the draw.
Lendmire’s network sets its own defined structures instead. Primary residences and second homes can choose between two:
- a 3-year interest-only draw followed by a 17-year fully amortizing repayment, or
- a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
Investment properties use the 5-year draw and 25-year repayment structure only. On both, at least 75% of the line is drawn at closing. Pricing floats through the draw and the repayment period and never converts to a fixed rate.
Walk through one lifecycle in words. The balance has not moved when the draw ends. It is then spread across the repayment years, so the payment now includes principal. Anyone planning to carry a balance should test whether the property or household budget can absorb that step.
Which Terms Should You Compare?
Compare how long you can borrow, how the payment changes, how pricing moves, and what it costs to leave. A low starting figure on a short draw can cost more in practice than a steadier line with a longer runway. Line up every offer on the same checklist.
| Term | What to look for |
|---|---|
| Draw length | How long you can borrow |
| Repayment length | Years to repay after the draw |
| Payment during draw | Interest-only or principal and interest |
| Balloon risk | Full balance due at draw end |
| Pricing structure | Index, margin, caps, adjustment frequency |
| Closing and ongoing fees | Annual, inactivity, early-closure |
| Draw rules | Minimum initial draw and later draws |
| Lien position | First or second lien |
Two points deserve extra attention. First, pricing on a floating line follows an index, so the margin is the part that stays constant and the part you can compare across offers. Caps limit the swing, but only if they exist, so check for them. Second, ask what happens if your plans change. Some lenders charge a penalty if you pay off or close the line early, and the cost depends on the lender.
How to Read the Disclosures
Start with the pricing page, then the repayment page, then the fee schedule. Look for three things in the pricing section: the index, the margin, and any cap. Then find the sentence that says what happens when the draw ends.
Check whether the payment turns into principal and interest, and whether any balance comes due all at once. Next, find the minimum draw rule, the inactivity fee, and the early-closure language. Write each answer down as you find it instead of relying on memory.
Also read the qualification language. Lenders on this type of loan commonly qualify the borrower using the interest-only payment calculated on the maximum draw, not on what is actually drawn. That means a small planned draw does not shrink the payment used to test your debt-to-income ratio.
What Does It Take to Qualify?
Qualifying rests on equity, credit, and debt-to-income, plus a property that fits the program. A HELOC is underwritten against your personal profile, which separates it from an investor loan.
Across the network, the key parameters are:
- Credit: the minimum score depends on occupancy: 600 on primary residences, 640 on second homes, and 700 on investment properties. Allowed leverage steps down as scores fall, so the lowest scores qualify for the smallest CLTV tiers. The credit report can be no more than 90 days old at closing.
- Debt-to-income: a 50% maximum, with a 45% limit for profiles from 600 to 679.
- Valuation: lines at or below $500,000 ordinarily use an automated valuation, and every line above $500,000 needs a full appraisal. A borrower may request a full appraisal in any case.
- Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural properties are not offered.
- Exposure: a borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
Past credit events carry seasoning periods. A bankruptcy needs four years from discharge or dismissal.
HELOC, Home Equity Loan, or Cash-Out Refinance?
A HELOC fits staged needs, a home equity loan fits one fixed need, and a cash-out refinance fits one large permanent need. The first two leave your first mortgage alone. The third replaces it.
| Factor | HELOC | Home equity loan | Cash-out refinance |
|---|---|---|---|
| Structure | Revolving line | Lump sum | New first loan |
| First mortgage | Stays in place | Stays in place | Replaced |
| Payment pattern | Interest-only, then amortizing | Amortizing from start | Amortizing |
| Best fit | Staged draws | One known cost | One large need |
For a rental owner, the first mortgage is the deciding variable. If you hold a favorable first loan, a line lets you keep it and add capital behind it. If the first loan is poor, replacing it may make more sense.
Where the General Rule Breaks for Rental Owners
Rental owners meet three exceptions: two kinds of rental HELOC, a stricter box on investment property, and first-mortgage restrictions.
Two different rental HELOCs. One is a line on your primary residence, with the money used to buy or fix a rental. The other is a line secured by the rental itself. The first puts your home at risk if the rental underperforms. The second adds a payment that the property has to carry.
A stricter box. WhiteCoat Investor reports that qualifying is often harder than for a primary residence and that fewer lenders offer these lines. NerdWallet adds that lenders consider default risk to be higher on rentals. Those general market findings match the network’s tiers above: investment lines top out at 70% CLTV, against 90% on a primary residence with a 720 or better profile.
A first mortgage that says no. Many first-mortgage documents restrict a second lien. Your note and servicer matter more than the line’s terms, so read yours before you shop.
Title. On the lines Lendmire arranges, the property must be held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC would need a vesting change or a different product.
Refinancing out of a line. If you use a line for a rehab and later refinance, the line must be paid off at that refinance. Cash-out refinances on rentals commonly expect about six months of seasoning, so plan the sequence early.
What Are the Risks, and When Is a HELOC the Wrong Choice?
A HELOC is the wrong choice when you cannot absorb a larger payment, when you plan to carry the balance for many years, or when the property needs an entity on title. The home or rental is the collateral, and floating pricing can raise the cost.
The CFPB notes that repayment schedules are often shorter than a mortgage’s and that payments are often significantly higher in repayment. In some cases the whole amount may be due as soon as repayment begins. Interest-only payments also mean the balance does not fall, which surprises many borrowers.
The problem is sharper on a rental. A floating, interest-only line adds a second obligation that can rise, and when it converts to amortization the property’s coverage tightens. A line also doesn’t wait for a vacancy to end.
Other situations where a HELOC is a poor fit:
- You need fixed pricing for a long hold.
- You want to buy or refinance with an LLC on title.
- Your credit sits below the investment-property floor of 700.
- You need a single large, permanent sum.
When a DSCR Cash-Out Refinance Fits Better
If the property is held in an LLC, if you need more equity than 70% CLTV allows on an investment line, or if you want fixed-structure options, a DSCR cash-out refinance often fits better. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Across Lendmire’s wholesale network, a cash-out refinance on a standard rental tops out around 75% LTV, while short-term-rental collateral caps near 70% on cash-out. Credit floors start at 620 in parts of the network, most programs want around 660, and 700 or better opens the strongest tiers. Loan sizes commonly reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Reserves vary by lender, leverage, and loan size, and about six months of PITIA is common.
Coverage works differently. A DSCR compares monthly rent to the monthly PITIA and nothing else. A 1.00 ratio is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing the number does not mean positive cash flow, since repairs, vacancy, and management sit outside the calculation. Term structures start from a 30-year fixed. Extended terms and interest-only periods are available through select lenders in the network.
The complete DSCR loans guide walks through those programs in full.
A Step-by-Step Way to Compare Offers
Gather at least three offers, fill in one worksheet, and total the cost over your expected holding period. A low starting cost can lose to a steadier line once fees and the repayment step are counted.
1. Confirm occupancy, lien position, and credit tier, since these set the ceiling.
2. Pull the first-mortgage documents and check for second-lien limits.
3. Request each offer’s draw length, repayment length, and payment type.
4. Record pricing structure: index, margin, caps, and adjustment frequency.
5. Add every fee, including early closure and inactivity charges.
6. Decide how long you expect to carry a balance and how you will exit.
| Term | Offer 1 | Offer 2 | Offer 3 |
|---|---|---|---|
| Draw / repayment years | |||
| Payment during draw | |||
| Balloon at draw end? | |||
| Index, margin, caps | |||
| Fees and early closure | |||
| Lien position |
Some terms can be negotiated, such as fees. Others are fixed by the program, such as the ceiling for your occupancy and credit tier. Knowing which is which saves time.
Frequently Asked Questions
Do I have to use my current mortgage lender for a HELOC?
Generally no, and shopping several lenders is part of comparing. What matters more is your existing first mortgage. If you hold a first loan that restricts a second lien, no outside lender can place a line behind it. Read your note and ask the servicer before you apply.
Does an interest-only draw mean my debt is shrinking?
No. During the draw you may pay only accrued interest, so the balance stays where it was. Principal begins to fall only after repayment starts. Plan for the larger payment that follows the draw, because the same balance is then spread across the repayment years.
Can an LLC take out a HELOC on a rental?
Not on the lines Lendmire arranges. Title must be held by an individual or a revocable living trust, so LLCs, corporations, and partnerships cannot hold it. An investor with a property already deeded to an LLC would need a vesting change or a different product, such as a DSCR cash-out refinance, subject to program terms.
How much can I borrow against a rental property?
On an investment property, the network ceiling is 70% CLTV, with a 700 credit minimum and lines up to $500,000. Your first mortgage uses part of that ceiling, and the line gets what is left. These figures are subject to lender guidelines and full file review.
Is a HELOC available on every property type?
No. Single-family, 2-4 units, PUDs, townhomes, and condominiums are eligible. Lines are also available only in Lendmire’s 16 full-service states, a narrower set than its DSCR footprint of 41 markets, including Washington, D.C.
