The Quick Read: The best program for your situation depends on occupancy, credit profile, and how much equity sits above the first lien. A HELOC can retire a remaining mortgage, but it swaps one home-secured debt for another and does not remove the debt. The line has to be large enough to cover the payoff and still fit under the combined loan-to-value cap.
- A payoff-sized line must cover the full payoff statement, not just the stated balance.
- Combined loan-to-value counts every lien, so a large remaining balance leaves little room.
- On an investment property, the network ceiling is 70% CLTV with a 700 minimum score and a $500,000 maximum line.
- Title must sit with an individual or a revocable living trust, not an LLC.
- The line floats in price and never converts to fixed on this network.
Lendmire is a mortgage broker, not a lender. It places these files with select wholesale lenders, and every figure below is subject to lender guidelines and full file review. This is not a commitment to lend. HELOC lending runs in Lendmire’s 16 full-service states only, narrower than the DSCR footprint.
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.
What Does “Best Program” Actually Mean Here?
There is no single best program. The right fit comes from four inputs: occupancy, credit tier, combined leverage, and how the property is titled. A broker that shops several wholesale lenders matches those inputs to a program. Ranking lenders by name answers a different question, and it misses the one that decides the file.
Occupancy sets the ceiling. The same borrower gets very different room depending on what the property is.
| Occupancy | Max CLTV | Min credit | Max line |
|---|---|---|---|
| Primary residence | Up to 90% (720+ only) | 600 | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | Up to 90% (720+ only) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
On a primary residence, the 90% tier applies at 720 or better and only up to a $500,000 line. Lines up to $750,000 on a primary residence run at 75% CLTV. A 700 score on an investment property reaches the same 70% ceiling as a 720. More credit does not buy more leverage there.
How Does a HELOC Pay Off a First Mortgage, Step by Step?
The mechanics are the same whatever the program. The order matters because each step can break the next one.
1. Pull the payoff statement. Ask the first-lien servicer for a payoff quote. It includes accrued interest and can exceed the stated balance. Yahoo Finance also flags possible prepayment penalties on the old loan.
2. Establish value. Lines at or below $500,000 ordinarily run an automated valuation instead of a traditional appraisal. A higher CLTV may call for a secondary valuation. A borrower can request a full appraisal in any case. Every line above $500,000 needs one.
3. Test combined leverage. Add the existing lien to the requested line and divide by value. For a payoff, the requested line must be at least the payoff amount. If the result lands over the cap, the line is too big for the equity.
4. Check borrower eligibility. The line is secured by the property but underwritten on the borrower: credit, DTI, and equity. DTI tops out at 50%, and 45% for scores from 600 to 679. The test uses the interest-only payment calculated on the maximum draw.
5. Close and draw. At least 75% of the line is drawn at closing. The draw pays off the first lien, and the new line becomes the only lien, in first position.
6. Repay. Payments are interest-only through the draw period, then the balance amortizes. The CFPB notes that after the draw period, payments are often significantly higher.
Can Your Equity Cover the Payoff?
Run the sizing before anything else. Three illustrative cases show where files land. These are modeled assumptions, not market data.
Strong fit. Picture a primary residence valued at $600,000 with a small remaining first mortgage. At 720 or better, the line fits well under the 75% CLTV tier. The payoff fits inside the line with room left over. Spare capacity stays available as credit.
Partial payoff. Say you own an investment property worth $400,000 with a mortgage balance near the cap. At 70% CLTV, the first lien already uses most of the allowed room. The line that remains may cover only part of the payoff. A line that only partly retires the first lien leaves two loans in place, which defeats the point.
Falls short. Consider a rental where the payoff exceeds 70% of value on its own. No HELOC line exists, because the first lien alone is above the cap. A DSCR cash-out refinance replaces the first mortgage instead. Lendmire’s complete DSCR loans guide covers how that product works.
Remember what a HELOC does not do. It does not cure a thin equity position. A larger line request only raises the CLTV, and the cap does not move.
Should You Pay Off the First Mortgage or Keep It?
Replacing a fixed first mortgage with a floating line is a bet on the index. The CFPB says HELOCs usually carry a variable rate, so payments can change month to month. On this network the line never converts to fixed.
| Factor | Keep the first mortgage | Pay it off with a HELOC |
|---|---|---|
| Payment type | Typically fixed | Floats through draw and repayment |
| Liens on the property | First lien plus any line | One lien |
| Unused credit | None | Line stays open |
| Payment reset risk | Low | Resets after the draw period |
| Underwriting basis | Varies by loan | Credit, DTI, equity |
A second-lien line is also available. Keeping a low first mortgage and borrowing against the remaining equity can beat a payoff when the first lien is cheap and the amount needed is modest. Run the comparison on a stress-tested payment, not today’s.
Which Structures Exist?
A standalone line can sit in first or second lien position. Two draw structures exist on primary residences and second homes. One runs a 3-year interest-only draw with a 17-year amortizing repayment. The other runs a 5-year draw with a 25-year repayment. Tennessee shortens both.
Investment lines run only the 5-year draw and 25-year repayment structure. The minimum line is $25,000, with a $10,000 floor in Michigan. After closing, the minimum subsequent draw is $1,000, with Texas at $4,000, as stated by the longer-runway wholesale program. The other wholesale program does not state subsequent-draw minimums.
Brokers see both programs in this network. The higher-leverage one reaches the top CLTV tiers. The longer-runway one offers the extended 25-year repayment and its own tradeline standards. Each figure applies only inside its own program’s terms.
Where Does the General Rule Break?
Several edge cases decide files before leverage ever comes up.
LLC-held rentals. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. This is the sharpest difference from a DSCR loan. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead. Files stall when the entity has to be unwound first.
Credit from 620 to 699 on a rental. The investment tier starts at 700. Below that, there is no HELOC path, and DSCR cash-out is the alternative.
Needs above $500,000. Lines above $500,000 are primary-residence only. They require a credit profile of 700 or better (720 on the longer-runway program), cap at 75% CLTV, and require a full appraisal.
Large first-mortgage balance. The line gets only the equity left under the cap. The first-mortgage balance decides how much line remains.
Primary-home line used to pay off a rental mortgage. This changes the collateral. A primary-residence line can reach a higher CLTV than a rental line. But it puts the home at risk instead of the rental, as Experian notes.
Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.
Property types. Single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable, are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural zoning are not offered.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program on primary residences and second homes. One seasons a foreclosure in 7 years and a deed-in-lieu, pre-foreclosure, or short sale in 4. The other declines that history regardless of age. Investment files follow the 7-and-4-year path.
State rules also bite. New Mexico and Ohio apply a CLTV cap tied to the credit profile. A property listed for sale, or listed within the past 60 days, is ineligible in several states. Confirm the state before pricing the file. A Texas primary residence is a homestead capping at 80% combined loan-to-value.
How Does a Rental HELOC Differ From a DSCR Cash-Out?
The two products answer different questions. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC is reviewed on personal credit and DTI and never looks at rent.
- A DSCR cash-out replaces the first mortgage. The HELOC can sit beside it or replace it.
- DSCR files can close in an LLC, subject to lender program eligibility. A HELOC cannot.
- A DSCR cash-out tops out around 75% LTV on most of the network, with about 6 months of seasoning common. The investment HELOC tops out at 70% CLTV.
- A HELOC’s payment reset can pull rental coverage down. If the line floats up, a rental that cleared 1.2x can slide toward 1.0x.
Investors with many financed properties often hit the DTI wall first. Lendmire’s piece Best Bank Statement HELOC Program to Pay Off Your Mortgage Faster covers documentation for borrowers whose income is hard to show on tax returns. Remember that a DSCR ratio compares rent to the full payment only. Clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, and management sit outside it.
What Are the Risks and Costs?
Rate type is the first risk. The line floats, so a payoff done on a low index can cost more later. Opendoor says the line freezes at the end of the draw period and the payment resets to principal plus interest. Stress-test that reset before signing.
The second is term reset. A lower interest-only payment can hide a longer payoff path. The third is foreclosure risk. The HELOC is secured debt, so the debt is moved, not erased. The fourth is prepayment charges on the old loan, which belong on the payoff statement.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Is It Worth It? A Simple Test
Compare three things in writing before committing.
1. The old payment against the line’s stressed payment, using an index several steps higher than today’s.
2. Combined leverage after the payoff against the cap, with cushion left.
3. The cost of switching to a DSCR cash-out if the HELOC fails the title or credit test.
Good fits usually share a few traits. They hold title individually or in a revocable trust. They have credit at or above the tier needed. They have a payoff small enough to leave real room under the cap. Poor fits have thin equity, an LLC deed, or a tight DTI.
What Should You Have Ready?
Prepare the file before any lender looks at it. Missing pieces are what stall HELOC files.
- A current payoff statement for the first lien.
- Vesting documents showing individual or revocable-trust title.
- A credit report no more than 90 days old at closing, with no rescores.
- Income documentation under the applicable program, subject to lender guidelines.
- A full list of financed properties and the lines on each.
- Any listing history on the property, since recent listings are ineligible in some states.
Credit pulls use a single-bureau score model keyed to the primary wage earner. The longer-runway program wants two tradelines seasoned 12 months, or one seasoned 24. Its housing history reads 0x30x6 and 1x30x12 at 640 and above, and 0x30x12 from 600 to 639. A broker can steer the file to the program whose overlays fit the borrower.

DSCR: The ratio of rent to the full monthly property payment.
Frequently Asked Questions
Can I use a HELOC to pay off an investment property mortgage entirely?
Only if the payoff fits under 70% CLTV on an investment property. The line cap is $500,000, the minimum score is 700, and title must be individual or a revocable trust. Because the new line becomes the only lien, it must cover the whole payoff. If it cannot, a DSCR cash-out is the usual alternative.
Does a higher credit score get me more leverage on a rental?
No. On an investment property, 700 and 720 reach the same 70% CLTV ceiling. Market surveys report investment-property HELOC caps of 70% to 75% across lenders, per Switchwize, but this network’s investment ceiling is 70%. Extra credit helps on primary residences and second homes, where the 90% tier requires 720 or better.
What happens if my rental is in an LLC?
The HELOC is unavailable. LLCs cannot hold title, so the property needs a vesting change first, or a DSCR cash-out, which can close in an LLC subject to lender program eligibility. Moving a rental into an LLC for liability reasons often closes the HELOC door.
Is the HELOC rate fixed or variable?
Variable. Pricing floats across the draw and repayment periods and never converts to fixed on this network. Some plans in the wider market let borrowers fix part of the balance, as the CFPB HELOC brochure describes, but that is not an option here.
Are HELOCs on investment property hard to get?
Yes, compared with primary-home lines. NerdWallet says fewer lenders offer them and caps run lower, since lenders see higher default risk. A broker that shops several wholesale lenders widens the field.
