Investment Property HELOC Credit and Equity Requirements for Investors

The Quick Read: Across Lendmire’s wholesale network, a home equity line of credit on a rental needs a credit score of at least 700 and caps combined borrowing, called combined loan-to-value or CLTV, at 70% of the property’s value, so the equity you leave untouched matters as much as your score. A score above 700 does not raise that ceiling. Your first mortgage balance decides how much line is left.

• Credit: 700 is a hard floor on an investment line, and 720 reaches the same 70% CLTV ceiling as 700.
• Equity: the first mortgage plus the new line cannot exceed 70% of value, and the line tops out at $500,000.
• Title: the property must sit in your personal name or a revocable living trust, not an LLC.
• Valuation: lines this size commonly run on an automated valuation, with no traditional appraisal.
• Availability: the product is offered only in the 16 states where Lendmire is a full-service mortgage broker, which is narrower than its DSCR footprint.

What Is an Investment Property HELOC?

An investment property HELOC is a revolving line secured by a rental you own. You borrow against equity, then repay over a set schedule. It is a niche product. Bankrate notes these lines aren’t nearly as common, or as easy to get, as HELOCs on a primary home. It also notes they are a type of second mortgage and that lenders weigh both the borrower’s creditworthiness and the property’s financials.

The structure on this network is specific. An investment line runs a 5-year draw period, then a 25-year repayment period. You make interest-only payments during the draw, and the balance fully amortizes afterward. At least 75% of the line is drawn at closing. Pricing floats during both periods and never converts to fixed.

The line can sit in first or second lien position. Lendmire is a broker and arranges these lines through select wholesale partners. It does not lend, and every figure here is subject to lender guidelines and full file review.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage balance 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.

Repayment period: The stretch after the draw ends, when you pay down the full balance on a fixed schedule.

Automated valuation: A model-based estimate of value used in place of a traditional appraisal.

DTI (debt-to-income): Your monthly debts divided by your monthly income, tested at the full draw.

DSCR (debt service coverage ratio): Monthly rent divided by the full monthly property payment, tested on the property instead of on you.

What Credit Does an Investment HELOC Require?

You need a score of at least 700. Investment is the strictest occupancy tier on this network, and no tier sits beneath 700. Primary residences can go lower, with a program floor of 600, but that does not carry over to a rental.

Credit above 700 buys nothing extra on leverage. A 720 and a 700 both reach the same 70% CLTV ceiling on an investment line. Your score decides whether you are eligible, not how much equity you can reach. A file at 700 with healthy equity beats a file at 760 with thin equity.

Other credit rules still apply:

• The lender uses a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.
• A bankruptcy needs 4 years of seasoning from discharge or dismissal.
• On investment files, a foreclosure needs 7 years of seasoning. A deed-in-lieu, pre-foreclosure, or short sale needs 4.
• DTI tops out at 50%. The lender reviews your file on the interest-only payment at the maximum draw, not the amount you plan to use.

The DTI point surprises many investors. Even if you intend to draw half the line, the lender tests you as if you drew all of it. Rental income documentation, such as leases, supports the file, but the line is underwritten mainly on you. For self-employed investors, business bank statements need a 680 minimum for deposit analysis. Investment already floors at 700, so that rule never becomes the binding constraint.

How Much Equity Do You Need?

You need enough equity that your first mortgage plus the new line stays at or under 70% CLTV. That is the ceiling on an investment property, with no higher tier. Market surveys report 75% to 80% combined caps on rental lines at banks, per Bankrate. On this network the investment ceiling is 70%.

The sizing is one subtraction. Take 70% of the property’s value, then subtract what you already owe. What remains is the most the line can be, subject to the $25,000 minimum and the $500,000 maximum.

The table has two lessons. First, a property you bought with 20% to 25% down has little room. A purchase at 75% to 80% LTV already sits above the 70% CLTV ceiling, so a new line has nothing to borrow against until you pay down the loan or the value rises. Second, a very valuable, lightly mortgaged property hits the $500,000 cap before it hits 70%. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Equity also protects you. Funding a down payment entirely with a line leaves no cushion if values drop. BiggerPockets’ Rookie Reply on borrowing against home equity explains the common alternative: draw on the primary home and pay the line down with cash flow.

How Does Underwriting Treat the File, Step by Step?

Underwriting follows a set order, and a weak step anywhere can stop the file.

1. Eligibility screen. The property type, title, state, and your portfolio count are checked first. A fail here ends the file before credit matters.

2. Credit. The lender pulls the score and checks the 700 floor and any derogatory seasoning.

3. Equity. The lender orders a valuation, then runs the CLTV math against your first mortgage balance.

4. DTI. Your debts, including the new line at its maximum draw, are tested against your income.

5. Documents. Expect proof of income, leases for the rental, and proof of property insurance.

Valuation deserves a closer look. Because an investment line caps at $500,000 and full appraisals begin only above that size, an investment line is structurally in the automated-valuation lane. A secondary valuation may be required at higher CLTV, and you may request a full appraisal in any case.

That choice matters after a renovation. An automated model may not see the value you just added. A full appraisal may support a higher value, depending on comps and underwriter review.

What Structures and Variations Exist?

The core structure is the 5-year draw and 25-year repayment, and it is the only one offered on investment lines. Other occupancies have additional options, but an investment property does not.

Here is how the pieces fit:

• Line size: $25,000 to $750,000 overall. Anything above $500,000 is for primary residences only.
• Subsequent draws: the minimum is typically $1,000 after closing on the longer-runway wholesale program, which offers the longer interest-only options.
• Exposure: you can hold up to three lines. Combined exposure caps at $2,000,000 on the higher-leverage wholesale program and $750,000 on the longer-runway program.
• Property types: single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos.
• Not offered: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, or agriculturally zoned property.

Compare that with a primary residence, where the ceiling reaches 90% CLTV only at a 720 or better credit profile. The investment line stays at 70%, which is the main reason rental owners find it tight.

The variable payment is the structural risk. The CFPB’s HELOC booklet says that on a variable-rate plan your monthly payments may change even if you don’t draw more money. The same booklet notes that some plans allow interest-only payments during the draw. When the draw ends, you enter a repayment period, as the CFPB’s explainer on how a HELOC draw and repayment period work describes. Underwrite the rental with the line’s payment included, not just the first mortgage.

Where Does the General Rule Break?

Several edge cases catch investors who thought they qualified.

Your rental sits in an LLC. This is the sharpest edge. Title must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change before a HELOC, or a different product. Entity-held rentals are a common reason investors get turned down. If that happened to you, Lendmire’s piece Investment Property HELOC for Investors Turned Down by a Credit Union covers the next steps.

You own many financed properties. A borrower with more than 15 financed properties is not eligible, whatever the equity.

The property was recently listed. In several states, a property listed for sale, or listed within the past 60 days, is ineligible.

You need more than $500,000. An investment line cannot go there, and larger lines are limited to primary residences.

Your equity is real but your score is 680. That score clears no investment tier. The fix is raising the score, not adding equity.

You are recycling equity after a rehab. The automated valuation lane and the 70% ceiling make this tight.

HELOC or DSCR Cash-Out: Which Fits?

Choose the product that matches where your strength sits. A HELOC is underwritten mainly on you. A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Pick the HELOC when you have strong personal credit, modest first-mortgage debt, and want flexible draws. Pick DSCR cash-out when your DTI is stretched, the property is in an LLC, or you want a larger sum.

On DSCR files, 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 does not mean positive cash flow, because repairs, vacancy, and management sit outside the calculation. Cash-out files commonly expect about 6 months of seasoning and reserves that vary by lender and loan size. Read the complete DSCR loans guide for the full mechanics.

A rental that clears 1.00 on coverage but fails the HELOC’s DTI test is a common mismatch. Brokers see it often because the two products test different things.

What Should You Do Before Applying?

Run a short self-test first.

• Pull your score and confirm it is 700 or higher.
• Calculate CLTV: first mortgage plus the line you want, divided by value.
• Confirm title is in your name or a revocable trust.
• Count your financed properties.
• Check that the property is not recently listed.
• Gather leases, income documents, and insurance proof.

If you fall short, fix the binding item first. Under 700 means credit repair. Over 70% CLTV means paydown or waiting for appreciation. LLC title means a vesting change or a DSCR cash-out.
