HELOC Lenders With the Highest Available Loan-to-Value Limit

The Quick Read: No single lender holds the top limit. The ceiling depends on how the property is used, your credit, and each lender’s appetite for risk. On the wholesale network Lendmire brokers through, an investment-property line tops out at 70% combined loan-to-value, and the higher ceilings exist only on homes you live in or use as a second home.

• Investment property: up to 70% CLTV, with a 700 credit score or better and a line up to $500,000, subject to lender guidelines.
• Primary or second home: up to 90% CLTV, but only at a 720 credit profile or better and on lines up to $500,000.
• Market surveys report 80% as a typical cap on investment lines, and many lenders sit lower. The network figure for investment lines is 70%.
• The first mortgage counts. The cap covers every loan on the property, so recent buyers often have no room left.
• A DSCR cash-out refinance is sized on rent instead, which is a different test entirely.

Why No Lender Owns the Top Number

The highest limit changes with the borrower’s file. A lender that stretches on a home you live in may cap a rental far lower, or decline it. Many lenders do not offer investment-property lines at all.

NerdWallet explains why: lenders see a higher default risk on rentals, so these lines are harder to get. Market surveys from that same source report a maximum of 80% on investment lines and 90% on primary homes. They also note that many lenders’ real thresholds sit below 70%. Treat those as market-wide figures. On Lendmire’s network, the investment ceiling is 70% CLTV and 90% appears only on primary and second homes at a 720 credit profile or better.

Lendmire is a mortgage broker. It works with a nationwide network of wholesale HELOC lenders, so it never lends the money itself. The useful question is not “which lender is highest?” It is which program fits your property, credit, and leverage need. The best program for your situation depends on those three things, and a broker that shops several wholesale lenders can match the file to the guideline.

How the Limit Gets Calculated

Every HELOC limit comes from the same formula: value × CLTV cap − existing loans = maximum line. CLTV (combined loan-to-value) is the share of the property’s value already pledged, counting every loan against it, including the new line. Most lenders count the full credit limit, not just what you draw.

Run it in percentages of value. These are modeled assumptions, not market data.

• Investment property, 70% cap, first mortgage at 50% of value. Room for a line of up to 20% of value.
• Investment property, 70% cap, first mortgage at 60% of value. Room shrinks to 10% of value.
• Investment property, 70% cap, first mortgage at 70% of value or more. Zero room. Not ideal, and common for recent buyers.
• Primary home, 90% cap at a 720 profile, first mortgage at 60% of value. Room for up to 30% of value, but the line still cannot exceed $500,000 at that leverage.

So comparing lenders really means comparing how many points of value remain after your first mortgage. A 90% headline means little if your first mortgage already uses 75% of the value.

What the Network Allows by Occupancy

Occupancy sets the tier before anything else does. Here are the network’s ceilings, each tied to its property use and credit tier.

Two points about the table. First, ceilings step down as scores fall. A primary residence reaches 85% at scores from 660 to 700, 80% at 640, and drops to 70% at 620 and 60% at 600. A second home floors at 640 and an investment property at 700, so those lower tiers apply to primary residences only.

Second, a line above $500,000 is for primary residences only. It caps at 75% CLTV, requires a full appraisal, and needs a credit profile of 700 or better (720 on the longer-runway line, described next).

Two line structures sit behind these numbers. The higher-leverage line has a 3-year interest-only draw followed by a 17-year repayment. Investment lines run the longer-runway structure only. Both are standalone lines in first or second lien position. Pricing floats during the draw and the repayment and never converts to fixed. Beyond 90%, nothing is available here. That includes the 95% and 100% lines you may see advertised elsewhere.

How Underwriting Treats a Rental Line, Step by Step

This is personal underwriting. It is not DSCR underwriting. The lender is mostly asking whether you can carry the debt, not whether the rent covers it. Here is how a typical file moves.

1. Credit. Lenders use a single-bureau score keyed to the primary wage earner. The report must be no more than 90 days old at closing, and rescores are not allowed. The program floor is 600, but investment lines start at 700.

2. Debt-to-income (DTI). DTI is your monthly debts divided by your monthly income. The maximum is 50%, and it is 45% for scores from 600 to 679. A ratio above 45% needs 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. Market sources cite a similar 40-50% range.

3. Valuation. Lines at or below $500,000 ordinarily use an automated valuation, with no traditional appraisal. A higher CLTV may call for a second valuation, and you can always ask for a full appraisal. Every line above $500,000 requires one. NerdWallet notes that rentals can require more than one appraisal.

4. Title. The property must be held by you personally or by a revocable living trust. More on that below.

5. Property. Single-family homes, 2-4 units, PUDs, townhomes, and condos all qualify, including non-warrantable condos. Modular factory-built homes are eligible on the longer-runway line only. A 2-4 unit property needs a 640 score on that line.

6. Closing draw. At least 75% of the line is drawn at closing. That matters because interest starts on that balance right away.

Rental income helps your DTI only partly, if at all. Portfolio investors often hit a personal DTI wall well before they reach the CLTV cap.

Where the Rule Breaks: Edge Cases That Change the Answer

A rented home is an investment property. If you rent the property out, it is underwritten as an investment, even if you call it a second home. The occupancy tier follows how the property is actually used.

An LLC cannot hold title. This is the sharpest structural difference from a DSCR loan. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead.

Exposure limits. A borrower is limited to three lines in total. Combined exposure caps at $2,000,000 on the higher-leverage line and $750,000 on the longer-runway line. A borrower with more than 15 financed properties is not eligible.

Credit history has seasoning rules. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year seasoning path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale. On primary and second homes, one program applies those same periods, while the other declines foreclosure history regardless of age.

Some property types are out. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.

Availability is narrower than DSCR. These lines are offered only in Lendmire’s 16 full-service states. That is a smaller footprint than the 41-market DSCR platform, which covers 40 states plus Washington, D.C.

A lender can shrink or freeze your line. The CFPB notes that if values fall significantly, a lender might decide not to allow additional credit. Its HELOC booklet shows the same logic as the formula above: the limit is a percentage of appraised value, minus what is owed. For the full mechanics, read Lendmire’s piece How Much a Value Drop Cuts a HELOC Limit and What an Appraisal Fixes.

There is no national cap on rentals. The Federal Reserve’s interagency real estate lending guidelines tell banks to set their own loan-to-value limits. That is why the cap on a rental line is a lender credit-policy choice and why it varies so widely. Lenders that keep loans on their own books can set their own limits. Lenders that sell loans follow the buyer’s rules. Neither is automatically more generous.

Key Terms Defined

• CLTV: the total of every loan on the property, including the new line, divided by the property’s value.
• Interest-only draw period: the early years when you can borrow from the line and pay only interest on the balance.
• Repayment period: the later years when you can no longer draw and the balance pays down with principal and interest.
• DTI: your monthly debt payments divided by your gross monthly income.
• Automated valuation: a computer estimate of value that stands in for a traditional in-person appraisal.
• DSCR: debt service coverage ratio, which compares a property’s monthly rent to its monthly principal, interest, taxes, insurance, and any association dues.

What Higher Leverage Costs You

A higher ceiling is not free. At 90% CLTV you keep a thin equity cushion. A modest drop in value can leave you underwater, and it can also lead a lender to freeze or reduce the line.

Payments float, so the cost of carrying a balance can rise without your changing anything. Interest-only draws feel light, but when the repayment period begins, the payment steps up because principal joins the bill. The CFPB warns that if you fall behind, you could lose your home. On a line secured by a rental, that means the rental.

Ask Every Lender These Questions

Published numbers conflict because lenders mix definitions. Before you rely on a figure, ask:

• Is that LTV or combined LTV?
• Is it a line or a fixed-rate home equity loan?
• Does it apply to owner-occupied, second-home, or investment property?
• Which credit tier does it belong to?
• What is the maximum line at that percentage?
• When is a full appraisal required?
• Can the lender freeze or reduce the line, and under what conditions?

A broker asks these for you across several lenders, then matches the answers to your file.

When a HELOC Is the Wrong Tool

If your rental has little room left, a line may not be the answer. Two alternatives are worth knowing.

A line on your own home. You can pull equity from your primary residence to fund a rental purchase. The line is underwritten on that home, so the home carries the risk if the rental struggles.

A DSCR cash-out refinance. 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. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The complete DSCR loans guide walks through how it works.

On this network, cash-out refinances top out around 75% LTV on standard rentals and 70% on short-term-rental collateral. About 6 months of seasoning is the common expectation. Most programs want a score around 660, with a 620 floor in parts of the network and 700 or better unlocking the strongest leverage. 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. These loans can close in an LLC, subject to lender program eligibility.

One caution. A DSCR number above 1.00 does not mean positive cash flow. It compares rent to the payment only, so repairs, vacancy, management, and utilities sit outside the calculation.
