The Quick Read: A lender sets a combined loan-to-value ceiling, counts every lien on the home including the full new line, and lets you borrow only the room under that ceiling, so a paid-off home starts from value times the ceiling, never from 100% of value, and other limits then trim the number further. Paid off does not mean unlimited.
- The ceiling depends on occupancy: investment properties top out at 70% combined loan-to-value, while primary residences and second homes reach 90% only at a 720-or-better credit profile.
- On a paid-off home the existing mortgage is zero, so the new line is the only loan counted.
- The accepted value, a dollar cap, credit tier, and debt-to-income ratio can each shrink the line before the equity ceiling does.
- Title matters: an LLC cannot hold title on these lines, which is the sharpest difference from a DSCR loan.
- Required equity is the unborrowable cushion. Available equity is what is left after that cushion.
What Does “Required Equity” Actually Mean?
Required equity is the share of your home’s value that must stay free of debt after the line is in place. If a lender caps combined leverage at 70%, it is requiring 30% of value to stay unencumbered. Same rule, two ways of saying it. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
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 borrowers hear “equity” and think of value minus mortgage. That is the plain definition, and the Consumer Financial Protection Bureau uses it for its description of a home equity line of credit. A lender then applies a ceiling below 100% to that value. The gap between your raw equity and the ceiling is the cushion you cannot touch.
Brokers see the same surprise on file after file. An owner with no mortgage assumes the whole value is on the table. The ceiling, set by the lender’s credit policy rather than by any federal formula, says otherwise.
Key Terms Defined
Home equity line of credit (HELOC): a revolving line secured by your property that you can borrow against repeatedly up to a set limit.
Combined loan-to-value (CLTV): all loans secured by the property, divided by the property’s accepted value.
Required equity: the portion of value a lender insists stay unborrowed, equal to 100% minus the CLTV ceiling.
Accepted value: the property value the lender actually uses, which may come from an automated valuation or a full appraisal and may differ from your own estimate.
Draw period: the stretch of the loan when you can borrow, usually interest-only, before repayment begins.
Debt-to-income ratio (DTI): your monthly debt obligations divided by your monthly income.
Lien position: the order in which lenders get paid from the property if the loan defaults. On a paid-off home, a new line is the first lien.
How the Equity Cap Becomes a Line Size
The line equals accepted value times the CLTV ceiling, minus every existing lien. Experian lays out the same formula and notes that credit and other factors can move the final limit up or down. Here is how it plays out in order.
1. Establish the accepted value. Lines at or below $500,000 ordinarily run an automated valuation rather than a traditional appraisal, though a higher CLTV may require a secondary valuation. A full appraisal is required on every line above $500,000, and you may request one in any case. A lower accepted value shrinks the line one-for-one.
2. Apply the ceiling for your occupancy and credit tier. The ceiling is not one number. It moves with whether the home is your residence, a second home, or a rental, and with your score.
3. Subtract existing liens. On a paid-off home this step is zero.
4. Apply the program’s dollar cap. On a high-value property, the maximum line can bind before the percentage does.
5. Test the borrower. Credit, DTI, and housing history decide whether the room under the ceiling is usable.
6. Set the structure. The line is a draw period followed by repayment.
The full new line counts in the CLTV, not just the amount you draw. Leaving most of it undrawn does not buy you extra room.
Paid Off Does Not Mean 100%: The Arithmetic
With no mortgage, the maximum line is simply accepted value times the ceiling. That is bigger than the same property would support with a mortgage on it, which is why a free-and-clear home is the strongest HELOC candidate. It is still a fraction of value.
Run it without dollars. On an investment property, the ceiling is 70% combined loan-to-value, so the cap is 70% of accepted value. If the valuation comes in 10% lower than you expected, the cap falls by the same 10%. Now take the identical property carrying a first mortgage. The mortgage balance comes off the top of that same 70%, so the line shrinks by exactly the amount owed.
| Scenario | What counts in CLTV | Line becomes |
|---|---|---|
| Paid off, investment | New line only | 70% of value, up to the cap |
| Mortgaged, investment | Mortgage plus new line | 70% of value minus balance |
| Paid off, valuation low | New line only | Ceiling applied to lower value |
The CFPB’s HELOC booklet says you can typically borrow up to a specified percentage of your equity, and it warns you could lose the home if you cannot repay. Both points matter here. The percentage is the lender’s choice, and the home is the collateral.
Ceilings by Occupancy
The occupancy of the property sets the ceiling, so quoting one number for every home is wrong. These are the figures on the wholesale network Lendmire works with, each tied to its occupancy and credit tier, and each subject to lender guidelines and full file review.
| Occupancy | Top ceiling | Credit needed | Max line |
|---|---|---|---|
| Investment property | 70% CLTV | 700+ | $500,000 |
| Second home | 90% CLTV | 720+ | $500,000 |
| Primary residence | 90% CLTV | 720+ | $500,000 |
Primary residences also carry a separate tier for larger lines. A primary-residence line above $500,000 caps at 75% CLTV, requires a full appraisal, and runs to a $750,000 maximum. The credit requirement for that larger line is 700 or better (720 on the program built around the longer 5-year interest-only draw). Investment lines never exceed $500,000 in total, and there is no tier above 70% for them.
Lower credit on a residence lowers the ceiling. A 640 score on a primary residence sits at 80% CLTV, and the ladder steps down from there. Investment lines floor at a 700 score, so a 720 score reaches the same 70% a 700 does. Better credit does not lift an investment ceiling.
Market surveys describe much higher figures for standard home equity lines on primary homes. Treat those as market-wide statistics about the wider lending world. For an investment property on this network, the ceiling is 70%.
What Trims the Line Below the Ceiling
Equity gives you the first number. Several other limits can cut it down before you ever see an offer. Check them in this order.
1. Valuation. The lender uses its accepted value, not your estimate. A self-estimate from a listing site is how most borrowers overshoot.
2. The dollar cap. A $500,000 maximum on investment lines means a very valuable rental never gets 70% of its value. A $750,000 maximum applies only to primary residences.
3. Debt-to-income. The maximum DTI is 50%, with a 45% limit for credit profiles from 600 to 679. A ratio above 45% requires a score of at least 680. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. NerdWallet reports that investment-property lines in the broader market lean on a DTI of roughly 40% to 50%.
4. Credit tier. Residences lose ceiling as the score drops. Investment lines simply stop below 700.
5. The draw requirement. At least 75% of the line is drawn at closing, so the line is not a pure undrawn safety net. It also carries a floating cost across the draw and repayment periods and never converts to fixed.
That last point surprises owners who wanted a standby reserve. A large line you must mostly draw on day one behaves more like a loan than a cushion.
How the Draw and Repayment Fit
Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Primary residences and second homes can choose between that structure and a 3-year draw with a 17-year repayment. After closing, a minimum subsequent draw applies, typically $1,000.
For comparison, NerdWallet describes the typical market line as a 10-year draw followed by repayment of up to about 20 years. Structures differ by lender, so compare terms rather than assuming.
Interest-only during the draw feels cheap and hides the real exposure. When repayment starts, the obligation steps up, and the cost floats the whole time. A borrower who sized the line to the ceiling should test the repayment phase before signing.
Where the General Rule Breaks
The equity ceiling is a good first estimate, and these are the cases where it misleads.
LLC-held rentals. Title must be held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change, or the owner moves to a DSCR cash-out refinance instead. Programs that lend to entities do so subject to program terms, and this one is not among them.
Property types. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. Modular factory-built homes are eligible only on the longer-runway program, and 2-4 unit properties need a 640 minimum there.
Exposure limits. A borrower is limited to three lines, with combined exposure capping 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.
Credit history. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history splits by program on residences, and investment files follow a seven-year foreclosure and four-year short-sale or deed-in-lieu path.
State rules. A handful of states apply their own caps or waiting periods to primary residences, and some bar properties that are listed or were recently listed for sale. These lines are available only in Lendmire’s 16 full-service states, a narrower footprint than its DSCR investor platform.
Acreage and the unusual. Rural parcels with acreage beyond program limits can fall out of eligibility in certain states.
How Investors Should Read the Cap
The decision comes down to two questions. How much equity can you reach, and which product measures the property the way you want it measured?
A HELOC is sized on equity plus your personal credit and income. A DSCR cash-out refinance is sized on LTV plus how well the property’s rent covers its full monthly obligation. It tops out around 75% LTV on a standard rental and 70% on short-term-rental collateral. DSCR programs also need enough coverage, with 1.00 being where select programs start. Clearing it is not the same as positive cash flow, because repairs, vacancy, management, and capex sit outside that calculation. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Consider an investor who owns a rental free and clear in her own name, with a 700 score. The cap is 70% of accepted value, so the line is limited by the lower of that and the $500,000 maximum. She keeps every dollar of equity she does not borrow, and she carries a line whose cost floats. That is the HELOC trade.
Now take a second investor whose paid-off duplex sits in an LLC. The equity is identical, yet the line is unavailable until title changes. This is where a DSCR cash-out refinance often takes over, since the loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
Honestly, this is a toss-up for many owners. The HELOC keeps leverage at 70% on an investment property and uses your personal credit. The DSCR route can leave more leverage available in exchange for a first-lien refinance of the whole property. Neither is better in the abstract, and the right choice depends on how much you need, how long you will hold the debt, and how many loans already sit on your credit file. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
For a side-by-side look at those two property types, see Lendmire’s piece Paid-Off Rental HELOC vs Home HELOC Equity Ceilings Compared. If you are an owner-occupant weighing a line on your own house, Lendmire’s explanation of how to qualify for a first-lien HELOC on a paid-off home walks through that file. The complete DSCR loans guide covers the rent-based alternative in full.
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 When Estimating Your Own Line
- Using your own value. The lender’s accepted value is the number that counts, and the two often differ.
- Assuming one ceiling. Occupancy and credit move it. Check the tier for the property you are actually borrowing against.
- Ignoring the dollar cap. A valuable rental can hit $500,000 before it hits 70%.
- Forgetting the DTI test. The lender reviews your file on interest-only payments at the maximum draw.
- Treating the line as a reserve. With at least 75% drawn at closing, you are borrowing most of it.
- Counting only the drawn balance. The full line limit enters the CLTV math.
- Overlooking title. If an LLC holds the deed, the line is not available as structured.
Frequently Asked Questions
Can a paid-off home get a HELOC?
Yes, and it is often the best-positioned candidate because the new line is the only lien counted. The ceiling still applies. The line starts at value times the CLTV ceiling for your occupancy and is then trimmed by valuation, the dollar cap, credit, and DTI.
Is the equity cap a law?
No. Federal rules do not set the percentage of equity you can borrow against. The cap is the lender’s or investor’s own credit policy, which is why ceilings differ so much between occupancy types and between programs.
Does the cushion apply when the line is fully drawn?
The full line limit counts toward CLTV whether or not you draw it. On this network at least 75% of the line is drawn at closing anyway, so the practical gap between limit and balance is small from day one.
Can I borrow 100% of my home’s value?
No. On an investment property the ceiling is 70% combined loan-to-value. On a primary residence or second home it reaches 90% only at a 720-or-better credit profile. The unborrowed remainder is the required equity.
Does a higher credit score always mean a bigger line?
Not always. On residences, a higher tier raises the ceiling, with the top tier at 720 and above. On investment properties the ceiling is 70% at both 700 and 720, so a higher score does not lift it.
