The Quick Read: a more affordable-looking HELOC is rarely the strongest offer, because the advertised figure leaves out the margin that applies after any introductory period, the fee stack, the minimum draw, the step-up when the draw ends, and the lender’s right to freeze the line, so a fair comparison puts every offer on the same written worksheet. Check eligibility first, then compare cost, then compare structure. For investors who plan to use the equity toward a rental purchase, the structure rows matter more than the starting price.
- Eligibility comes before price. Occupancy, credit tier, combined leverage, and line size decide which offers you can actually receive.
- Compare the margin, not the teaser. The formula after the discount period is the lasting cost.
- Price the full fee stack, including minimum draws, annual fees, and early-closure terms.
- Model the day the interest-only period ends, not just the first year.
- Ask how and when the lender can freeze or shrink the line before you count on the cash.
Why a Low Starting Number Misleads
An advertised HELOC figure is a snapshot, not a price. It usually reflects a discount period, a specific credit tier, and a specific draw amount. Change any one of those and the figure changes with 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.
Most HELOCs float. The cost of borrowing is an index plus a margin, and the index is the same no matter which lender you pick. That makes the margin the one number that is truly comparable across offers. A lender that advertises a low starting figure with a thick margin can cost more over time than a lender with a plainer start and a thin margin.
Teaser periods need a second question: what is the margin once the discount ends? An introductory price that sits below the index can reverse quickly once the formula takes over. Ask for the post-introductory margin in writing, along with how often the price adjusts and whether there is a cap or a floor on each adjustment.
One structural fact surprises many borrowers. Across the select wholesale programs Lendmire places primary-home lines with, pricing floats through both the draw and the repayment period and does not convert to fixed. Many retail HELOCs let you lock part of the balance. If a fixed-price lock matters to you, it is a reason to compare this structure against other products, and the worksheet below makes that visible.
Filter by Eligibility First
Eligibility is the first filter. Comparing a quote you cannot receive wastes your time and can cost an application fee. Four inputs decide most outcomes: occupancy, credit profile, combined loan-to-value, and line size.
Combined loan-to-value (CLTV) adds your first mortgage and the new line, then divides by the home’s value. The equity-room formula is simple. Take the home’s value, multiply by the CLTV ceiling that fits your credit tier, subtract your existing liens, and then apply the line-size cap. Whatever is lowest is your room.
Here is the formula in percentages. Say your first mortgage sits at 60% of the home’s value and your credit profile supports an 85% CLTV ceiling. That leaves room for a line worth up to 25% of the value, subject to the line cap and the lender’s review. Add a higher first mortgage and the room shrinks one-for-one.
On a primary residence, the select wholesale programs in Lendmire’s network step the ceiling by credit tier. These are typical guideline ranges, subject to lender guidelines and full file review:
| Credit profile | Max CLTV (primary home) | Max line at that CLTV |
|---|---|---|
| 720+ | 90% | $500,000 |
| 660+ | 85% | $500,000 |
| 640+ | 80% | $500,000 |
| 620+ | 70% | $400,000 |
| 600+ | 60% | $400,000 |
The 90% ceiling exists only at a 720 credit profile. Below that, the ceiling steps down, and the network floor is 600.
The network runs on two wholesale programs, and where their terms differ, each figure here applies only within its own program. A 720 profile on a primary home carries a real tradeoff. You can take 90% CLTV on a line up to $500,000, or take a larger line up to $750,000 at a reduced 75% CLTV. The larger line requires a credit profile of 700 or better (720 on the longer-runway program, the one built around the five-year interest-only draw), a full appraisal, and a primary residence. If you need the extra room, you give up leverage. If you need the leverage, you give up size.
Debt-to-income is the other gate. The ceiling is generally 50%, and it drops to 45% for credit profiles from 600 to 679. Qualification typically runs on the interest-only payment calculated on the maximum draw. That detail matters when you compare offers, because a lender that tests the full line can qualify you for less than one that tests only what you draw.
Two more eligibility checks catch borrowers off guard:
- Title: The home must be held by you personally or by a revocable living trust. An LLC, corporation, partnership, or land trust cannot hold title on these lines.
- Property type: Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial or agricultural properties are not.
This product is also only available where Lendmire operates full-service mortgage brokerage, which covers 16 states. That is narrower than the 41-market DSCR footprint, so confirm your state before you collect quotes.
The Comparison Worksheet
Put the same questions to every lender, in writing, and fill in one column per offer. The Consumer Financial Protection Bureau’s HELOC brochure includes a worksheet for exactly this purpose, and lenders must hand borrowers the brochure when they provide an application, per the CFPB’s consumer information page. The rows below follow that structure and add the ones that matter most to investors.
| Row | What to ask | Red flag |
|---|---|---|
| Pricing formula | Index, margin, adjustment schedule | Only a single figure offered |
| Discount period | How long, and what margin follows | Margin withheld until closing |
| Caps and floors | Limits on each adjustment | No cap, or a high floor |
| Fee stack | Appraisal, origination, annual, inactivity | Fees waived only with a catch |
| Minimum draw | Amount funded at closing | Large forced draw |
| Draw and repayment | Length of each, payment type | Balloon at the end |
| Freeze rights | Triggers for freezing or cutting | Vague triggers |
| Early closure | Fee clawbacks, exit costs | Steep exit charges |
Two rows deserve extra attention.
The first is the minimum draw. Across the primary-home programs Lendmire works with, at least 75% of the line is drawn at closing. That makes the line behave like a funded loan from day one, and the payment starts on that balance whether you need the cash or not. A lender with a low minimum draw gives you real flexibility. A lender with a high one costs you carry on money you may not have a use for yet.
The second is the structure of the draw. Two draw structures exist on primary residences. One is a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other is a 5-year interest-only draw followed by a 25-year repayment. A few states shorten both. The longer runway delays the payment step-up, and the shorter one starts paying principal sooner. Neither is wrong, but they fit different plans.
Run a Two-Offer Comparison
Consider two offers described in words rather than dollar figures.
Offer A advertises the lowest-looking starting figure. It carries a discount period of limited length, a higher post-discount margin, an origination fee, and an annual fee. Offer B starts higher. It has a thinner margin from day one, no annual fee, and a smaller minimum draw.
Over a short hold with a modest balance, Offer A can win, because the discount period covers most of the time you carry the debt. Over a long hold, or with a larger balance, Offer B tends to win, because the lasting margin does the damage over time and the fee stack compounds. If you plan to repay inside the discount window, Offer A’s early-closure terms become the deciding row.
Do not compare these offers on the first twelve months alone. Decide your holding period and expected balance first, then test each offer against both. The offer that wins depends on how long you carry the balance, how much you draw, and what the early-closure terms cost you.
What the Repayment Phase Does to Your Budget
The payment you pay during the draw is not the payment you pay after it. During the interest-only period, you cover interest on what you drew. When the draw ends, the line converts to a fully amortizing schedule, and principal joins the payment. Because pricing keeps floating, the payment can also move with the index.
Ask each lender to show you the payment structure at the start of the repayment phase on your expected balance. A 25-year repayment spreads the step-up over a longer period than a 17-year one, though the draw period is also longer in that structure. Compare the two phases together, not separately.
This is also where primary-home risk becomes concrete. The collateral is the home you live in. The CFPB’s brochure states the worst case plainly: if you fall behind or cannot repay on schedule, you could lose your home. Offers that give you payment predictability, sensible caps, and the ability to stop borrowing deserve extra weight for that reason.
Freeze, Reduce, and Cancel Rights
A line of credit is not cash in hand. The CFPB’s brochure notes that lenders generally can freeze or reduce a line if the home’s value falls significantly or your circumstances worsen. That matters most when your plan depends on a funded purchase.
Ask each lender to name its freeze and reduction triggers in writing. The more specific the trigger, the easier it is to judge the risk. A lender that cannot state its triggers clearly is telling you something.
Federal rules also set limits after the line opens. Under the eCFR’s change-in-terms rules, a lender that changes terms generally owes written notice at least 15 days before the change takes effect, and it must send written notice when it stops further advances or cuts the limit. Fees on an opened plan generally cannot rise. That protects you from price creep, though it does not stop a lender from freezing draws under the triggers in your agreement.
Where the General Rule Breaks
Several edge cases change the comparison, and an investor should know them before choosing.
Renting the home out. Many HELOC agreements restrict or prohibit renting the home to others, and the CFPB brochure warns about this directly. If you might convert your primary home to a rental later, read the occupancy language before you sign. A line written for a primary residence is not a line written for a landlord.
Primary versus rental collateral. A HELOC secured by a rental puts that rental at risk, while a line secured by your primary home puts your home at risk. Experian notes that rental-secured lines generally demand stronger credit, lower debt ratios, and larger reserves. In the network Lendmire works with, an investment-property line caps at 70% CLTV, runs only the 5-year draw and 25-year repayment structure, and stops at $500,000 total. A primary home reaches higher, but the highest leverage and the largest line do not come together:
| Factor | Primary residence | Investment property |
|---|---|---|
| Max CLTV | 90% (720+ only, line to $500,000) | 70% |
| Largest line | $750,000 at 75% CLTV (700+, full appraisal) | $500,000 |
| Draw structures | 3/17 or 5/25 | 5/25 only |
Business accounts. If you plan to qualify using business bank statements, the deposit analysis requires a 680 minimum. A 640 borrower can qualify for the line itself but cannot use business accounts, which is a real gate on a primary residence where the floor is 600.
Past credit events. A bankruptcy needs 4 years of seasoning on both programs. Foreclosure history splits: one program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4, while the other declines the history regardless of age.
State terms. A handful of states apply their own caps or shorter repayment periods. Confirm state terms before you compare, because they can change which offers are even available to you.
Tax treatment. 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.
Using Primary-Home Equity Toward a Rental
Many investors take a HELOC on their own home to fund the down payment on a rental. It can work, but the structure deserves a hard look before you commit. BiggerPockets commentary confirms that some lenders allow a HELOC for a rental down payment, including with a DSCR loan. It also raises the question that matters most: are you willing to risk your primary residence to buy a rental?
Two tests run in parallel. The HELOC qualifies you personally, on income, credit, and debt-to-income. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Across the network, most purchase files land at 75%-80% LTV, and select programs reach 85% LTV with roughly a 700+ score. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.
Keep a few points straight. DSCR compares rent to the full monthly obligation of principal, interest, taxes, insurance, and any HOA dues. It does not measure cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Your HELOC payment also sits outside the DSCR figure, yet you still pay it from personal income. Reserves on the DSCR side commonly run around 6 months of the monthly obligation, though they vary by lender, leverage, loan size, and transaction type.
Borrowed down-payment money also raises sourcing and reserve questions that differ by program, so confirm how a given DSCR lender treats HELOC funds before you apply. For the full picture of how rental financing works, see Lendmire’s complete DSCR loans guide. For a walkthrough of the strategy itself, Lendmire’s piece How to Use a Bank Statement HELOC on Your Primary Home to Buy a Rental covers the mechanics.
The investor profile decides whether this is wise. A borrower with strong income, a modest first mortgage, and a rental that clears coverage comfortably is in a different position from one who needs the HELOC to make the purchase work at all. If a deal only works when you borrow against your home, that is a signal to revisit the deal, not the loan.
Valuation and Credit Details
Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation. A full appraisal is required on every line above $500,000, and you can request one in any case. Appraisal terms often differ between lenders, so ask whether the cost is waived or charged.
Credit reports can be no more than 90 days old at closing, and the programs use a single-bureau score model keyed to the primary wage earner. A borrower is limited to three lines, and a borrower with more than 15 financed properties is not eligible. If you own many rentals, run that count before you start collecting quotes.
Key Terms Defined
Margin: The fixed number a lender adds to the index to set your borrowing cost, which stays the same while the index moves.
Index: The published benchmark that your pricing follows, which is the same no matter which lender you choose.
CLTV: Your first mortgage plus the new line, divided by the home’s value.
Draw period: The stretch when you can borrow against the line and usually pay interest only.
Repayment period: The stretch after the draw when the balance amortizes and principal joins the payment.
Minimum draw: The amount you must fund at closing or with each advance, whether you need the cash or not.
Frequently Asked Questions
Is the lowest advertised offer a more affordable HELOC?
Not reliably. The advertised figure often reflects a discount period that ends, and the margin that applies afterward is the lasting cost. A higher starting figure with a thinner margin and fewer fees can cost less over a long hold. Compare offers on the margin, the fee stack, and your expected balance and timeline.
How many offers should I collect?
Three is a practical number because it matches the worksheet format and gives you leverage to negotiate fees. Use the same questions with each lender and get terms in writing. Multiple HELOC applications can show up on your credit file, so gather quotes within a short window and ask whether a lender can share terms before a full application.
What happens when the draw period ends?
The line stops being interest-only and converts to a fully amortizing schedule. Principal joins the payment, and because pricing floats, the payment can also move with the index. On the primary-home programs Lendmire places files with, the repayment period runs 17 or 25 years depending on the draw structure, and a few states shorten both.
Can a lender freeze my line?
Yes, under the triggers written in your agreement, such as a significant drop in the home’s value or a worsening of your circumstances. Ask each lender to name the triggers specifically, and do not count on an unfunded line as cash for a time-sensitive purchase.
Can an LLC hold the home for these lines?
No. Title must sit with you personally or with a revocable living trust. A property already deeded to an LLC would need a vesting change, or a DSCR cash-out refinance might be the better route, subject to program terms.
