The Quick Read: Usually less than you expect. On an investment property, the most a line can reach across the wholesale network Lendmire works with is 70% combined loan-to-value (CLTV), minus every loan already on the property, and never more than $500,000 in total.
- The formula: property value × 70% CLTV − existing liens = the most the line can be, subject to lender guidelines.
- The hard ceiling: investment lines run from $25,000 to $500,000, and no investment line goes beyond that.
- Credit buys eligibility, not leverage: 700 is the floor, and a 720 score unlocks no higher percentage on a rental.
- Title matters: the borrower must hold title personally or in a revocable living trust. An LLC cannot hold title.
- California: the same investment-property rules apply, and California is one of 16 states where Lendmire offers home equity lines.

How large a line the equity supports in California.
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 Is the Maximum Line Calculated?
The maximum line equals the property’s value times the lender’s CLTV cap, minus everything already borrowed against it. That is the whole formula. The only wrinkles are the dollar cap, the minimum line size, and your personal qualifying.
Equity is simply what the property is worth minus what you owe. A lender will not let you borrow all of it. The federal consumer-finance regulator’s HELOC booklet shows the same method. It takes a percentage of the appraised value and subtracts the balances already owed. The booklet uses 75% only as an illustration of the arithmetic, not as a rule.
On an investment property, the network’s cap is 70% CLTV. CLTV means combined loan-to-value: your first mortgage plus the new line, divided by the property’s value.
Here is the sequence a lender follows:
1. Establish value. On an investment line, this is almost always an automated valuation.
2. Apply the 70% cap to that value.
3. Subtract existing liens. This means your first mortgage plus any other second liens.
4. Apply the dollar limits. The line cannot exceed $500,000, and it cannot fall below $25,000.
5. Test you. Credit, debt-to-income, and eligibility of the property and title decide whether any line is offered.
What the Math Looks Like Across Different Loan Balances
The fastest way to see the result is to hold the cap at 70% and vary how much of the property’s value is already borrowed. Everything below is a percentage of value, so you can apply it to any California rental.
| First mortgage as % of value | Room left under 70% CLTV | What it means |
|---|---|---|
| 50% | 20% of value | Strong room for a line |
| 60% | 10% of value | Moderate room |
| 65% | 5% of value | Thin; may fall under the minimum line |
| 70% or more | None | No line available |
| No mortgage | 70% of value | Cap or the $500,000 limit, whichever is lower |
Two edge cases deserve attention.
The dollar cap can bind first. California values run high. A free-and-clear rental can have 70% of its value exceed $500,000. In that case the $500,000 line limit decides the answer, and the CLTV test no longer does. The percentage cap protects the lender on modest properties, and the dollar cap does the same on expensive ones.
A thin gap may be too thin. The minimum line is $25,000. If your first mortgage already sits near 70% of value, the remaining room may not reach that floor. The lender then has nothing to offer, whatever your credit looks like.
The valuation step matters here, because value is the first multiplier. Lines at or below $500,000 ordinarily run on an automated valuation with no traditional appraisal. A higher CLTV may call for a secondary valuation. You can also request a full appraisal in any case. Since an investment line tops out at $500,000, investment lines sit in the automated lane by design.
Why Is the Rental Ceiling Lower Than on Your Own Home?
Lenders treat a rental as riskier than a home you live in, so the cap is lower. On this network, a primary-residence or second-home line can reach 90% CLTV, but only for borrowers with a 720 or better credit profile. An investment property tops out at 70% CLTV, with no tier above it.
That gap explains a common mistake. Investors hear that a home equity line can reach 80% or 90% of value. Those figures describe the owner-occupied tier. Applying them to a rental overstates your borrowing power by a wide margin.
Credit works differently on the investment tier, too. A 720 score and a 700 score both reach the same 70% CLTV and the same $500,000 ceiling. The minimum is 700, and nothing sits beneath it. A stronger score keeps you eligible. It does not raise the cap.
The same ceiling logic runs through the rest of the loan file. An excellent score will not erase a leverage cap, and a large amount of equity will not erase a credit floor.
What Else Can Shrink Your Line?
Several things besides the CLTV cap can cut the amount, or end the application before sizing begins.
Debt-to-income. A HELOC is underwritten on you, not on the property’s rent. The network allows a maximum debt-to-income ratio of 50%. It drops to 45% for credit profiles between 600 and 679, and a ratio above 45% requires a 680 minimum. On an investment line the 700 credit floor already clears these thresholds. Qualifying uses the interest-only payment calculated on the maximum draw, not on the amount you choose to borrow. A big approved line can therefore lift your qualifying payment even if you draw little after closing.
Title and vesting. The line must be on a property held by you personally or by an inter vivos revocable living trust. That is a trust you create during your lifetime and can change. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If your rental is already deeded to an LLC, you need to change the vesting or use a different product.
Property type. Eligible properties include single-family homes, 2-4 unit buildings, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not eligible.
Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. For investment files, a foreclosure needs 7 years and a deed-in-lieu, pre-foreclosure, or short sale needs 4. The credit report must be no more than 90 days old at closing, and no rescores are allowed.
Your overall exposure. A borrower is limited to three lines in total. An owner with more than 15 financed properties is not eligible.
Listing status. In some states, a property listed for sale or listed within the past 60 days is ineligible. California is not among them, but check the rule if you buy and sell in other states.
How Does the Line Behave After You Get It?
An investment line runs on a 5-year draw period, during which you pay interest only. A 25-year repayment period follows, during which the balance fully amortizes. At least 75% of the line is drawn at closing. Pricing floats through both the draw and the repayment period and never converts to fixed.
The federal CFPB explains that a HELOC is an open-end line you can draw on repeatedly during the draw period. It also warns that a significant drop in home value can lead a lender to stop further draws. Do not plan on the full line staying available forever.
The structure is a standalone line in first or second lien position. If you already have a first mortgage, the line sits behind it. A HELOC behind an existing mortgage is a second mortgage. You pay it in addition to the first one.
The risk is real, and it is the same risk as any loan secured by the property: the collateral can be taken if you do not repay. A variable-priced line with an interest-only draw can feel cheap until repayment begins. Stress-test your own cash flow at the point the 25-year amortization starts.
Where Do Most Investors Get the Wrong Number?
A few mistaken assumptions cause most of the surprises.
“I can borrow 80–90% of value.” That is the owner-occupied tier, and 90% on this network requires a 720-plus profile. The investment ceiling is 70% CLTV.
“I can borrow all my equity.” The cap stops short of full equity by design. And a dollar limit can bind before the percentage does.
“A higher score means a higher line.” On this network, scores above 700 do not raise the investment cap. They only keep you eligible.
“Any lender will do a HELOC on a rental.” The pool is small. An investor discussion on BiggerPockets makes the same point: few banks do rental HELOCs, though some exist. Large retail lenders often decline them entirely. A broker with access to several wholesale partners can search where one bank would say no.
“Moving the rental into an LLC is always safer.” For liability purposes, it may be. For a HELOC, it removes eligibility, since the line requires personal or revocable-trust title.
“A HELOC and a DSCR loan are the same thing.” They are different products, and the next section covers how.
HELOC or DSCR Cash-Out Refinance?
The two products answer different questions. A HELOC looks at you: your credit, your debt-to-income ratio, your equity. A DSCR loan looks at the property: the rent compared with the full monthly payment of principal, interest, taxes, insurance, and any association dues (PITIA). DSCR means debt service coverage ratio. Our complete DSCR loans guide walks through the full mechanics.
| Factor | Investment HELOC | DSCR cash-out refinance |
|---|---|---|
| Underwritten on | Your credit and income | Property rent vs. payment |
| Max leverage | 70% CLTV | Around 75% LTV on standard rentals |
| Title | Individual or revocable trust | LLC, subject to lender program eligibility |
| Structure | Revolving line, second lien | New loan replaces the old one |
| Loan size | $25,000 to $500,000 | Up to $3,000,000 on standard programs |
A few points sit behind that table.
On a DSCR cash-out refinance, the network tops out around 75% LTV, with about 6 months of seasoning as the usual expectation. Seasoning is the waiting period a lender wants between buying a property and refinancing it. Credit floors start near 620 in parts of the network, with most programs wanting around 660 and 700-plus unlocking the strongest tiers.
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. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation.
Roughly, a HELOC fits when you want revolving access, hold title personally, and have strong credit and low personal debt. A DSCR cash-out fits when the property sits in an LLC, you own many properties, or personal debt-to-income is heavy. DSCR programs are available across 41 markets, including Washington, D.C. The home equity lines here cover a narrower 16-state footprint.
What About California Specifically?
California rental investors face the same investment-property rules as anyone in the network’s footprint. The 70% cap, the $500,000 ceiling, the 700 floor, and the title rules do not change at the state line. There is no California-specific leverage overlay to plan around.
What does change is how often the dollar cap matters. Higher property values mean the $500,000 ceiling binds more often than it would in a lower-priced market. A California investor with a free-and-clear rental can run into the dollar cap before the percentage cap. Another with a heavy first mortgage can run into the CLTV cap before either. Run both tests on every property.
California is also one of the states where Lendmire offers these lines. Check your specific property and title against the eligibility rules above before spending time on an application.
Can You Use a Line on Your Home to Fund a Rental?
Yes, and it is a different calculation. A line on your own primary residence follows the owner-occupied tier, which is more generous than the investment tier. It is easier to qualify for. But you are putting your home at risk to finance a rental. If the rental underperforms, you owe the same balance, and your home is the collateral. The federal consumer-protection cautions about borrowing against your home apply fully here.
Another idea gets repeated among investors: open the line while the house is still your primary residence, then convert it to a rental. Check the lender’s terms and occupancy conditions before you try it. Occupancy declared at closing is a representation, and lenders hold borrowers to it.
Key Terms Defined
CLTV (combined loan-to-value): your first mortgage plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line and pay interest only. Investment lines run 5 years.
Repayment period: the stretch after the draw ends, when you pay down principal and interest. Investment lines run 25 years.
Lien position: where your loan stands in line to be repaid. A first lien is paid before a second lien.
Vesting: how title is held, such as individually, in a trust, or in an LLC.
Automated valuation: a computer-generated estimate of value, used instead of a traditional appraisal.
Frequently Asked Questions
What is the maximum HELOC on an investment property?
The most you can borrow is 70% of the property’s value, minus all existing liens, and never more than $500,000. The minimum line is $25,000. Credit above 700 does not raise this ceiling on a rental. Everything is subject to lender guidelines and a full file review.
Can I get a HELOC on a rental held in an LLC?
No. The line requires title in your own name or an inter vivos revocable living trust. If the rental is already in an LLC, you would need to change the vesting or consider a DSCR cash-out refinance instead, subject to lender program eligibility.
What credit score do I need for an investment property HELOC?
A minimum of 700. Scores of 700 and 720 both reach the same 70% CLTV on an investment line, so a higher score does not buy more leverage. A 600 program floor exists on other occupancy types, but it does not apply to rentals.
Does a rental HELOC need an appraisal?
Usually not. Lines at or below $500,000 ordinarily use an automated valuation. A higher CLTV may call for a secondary valuation, and you can request a full appraisal in any case. Full appraisals are required on lines above $500,000, which are limited to primary residences.
Does rental income help me qualify?
A HELOC is underwritten on your personal credit and debt-to-income ratio, with a maximum of 50%. The lender reviews your file on the interest-only payment calculated on the full line amount. If you want the property’s rent to carry the loan, a DSCR product is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
