How Much a HELOC Lends Compared With a 401k Loan Limit

The Quick Read: A 401k loan tops out at the lesser of half your vested balance or $50,000 no matter how much you have saved, while a HELOC has no fixed dollar cap and instead lends a percentage of your home’s value, minus what you already owe, with ceilings that depend on occupancy and credit.

• A 401k loan is limited by your plan balance. A HELOC is limited by your property’s equity.
• On a rental you own, the network ceiling is 70% combined loan-to-value (CLTV), with a minimum 700 credit score and a maximum line of $500,000.
• On a primary residence, the ceiling reaches 90% CLTV only at a 720+ credit profile, on lines up to $500,000.
• A 401k loan on a rental purchase gets a 5-year term. The longer term is reserved for a main-home purchase.
• Neither one automatically counts as a down payment on a DSCR purchase. Each lender’s treatment of borrowed funds differs. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Investors usually ask this question because they want cash for the next down payment. The two products answer it in opposite ways. One is capped by a retirement account, the other by real estate. Knowing which wall you hit first is most of the decision.

What Sets a HELOC Limit?

A HELOC limit is a lender-set percentage of the property’s value, minus every lien already on it. There is no federal dollar cap. Equity is the starting point, but the lender never lends against all of it. The CLTV ceiling keeps a cushion in place.

The formula runs in three steps:

1. Take the property value, usually from an appraisal or an automated valuation.

2. Multiply it by the lender’s maximum CLTV.

3. Subtract the existing mortgage and any other liens.

What remains is the most the line can be. Credit, income, and debt load can pull it lower.

Market surveys show how this plays out. Experian reports that typical HELOC ceilings run up to 85% of home value across all mortgages, with some lenders going higher. Its worked example uses a $500,000 home with $250,000 owed, which yields about $175,000 at that 85% market figure. That is a market-wide statistic. Across Lendmire’s wholesale network, the ceiling depends on occupancy, as the next section shows.

The Network Ceilings by Occupancy

On the select wholesale lenders Lendmire works with, occupancy sets the ceiling more than anything else. Lendmire is a broker. It arranges these lines and does not lend them. Every figure below is subject to lender guidelines and a full file review.

Lower credit tiers step the ceiling down. On a primary residence, a 700+ profile reaches 85% CLTV on lines up to $500,000, and a 640+ profile reaches 80%. A line above $500,000 is available on a primary residence only. It requires a 700 credit profile or better (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal. The maximum line anywhere is $750,000.

Texas adds a wrinkle. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. The higher matrix tiers never apply there.

The investment-property row is the one most readers should study. Say you own a rental with a first mortgage equal to about half its value. A 70% ceiling leaves only about 20 points of value to borrow against, before any cushion. The same owner on a primary residence at 720+ could see far more room. Occupancy changes the math as much as equity does.

How a 401k Loan Limit Works

A 401k loan limit is the lesser of 50% of your vested balance or $50,000, and only if your plan allows loans. The IRS 401(k) resource guide sets out that rule. It also says repayment generally runs within five years, with payments that are substantially level and made at least quarterly.

Three parts of that rule trip people up.

Vested balance, not total balance. Your own deferrals are always fully vested. Unvested employer match is excluded from the base.

The plan must permit loans. The plan document decides. Many plans also limit how many loans you can hold and what they can be used for.

Outstanding loans count. Multiple plan loans are aggregated. A balance outstanding in the prior twelve months can shrink the $50,000 ceiling.

The arithmetic is simple. A $60,000 vested balance supports a loan of up to $30,000. At a $100,000 vested balance, half is exactly $50,000. Beyond that point, more savings changes nothing. Some plans also allow a loan of up to $10,000 when half the balance falls below that figure, but that depends on the plan.

A loan that exceeds the limit, lacks a written agreement, or misses payments is treated as a taxable distribution under the IRS rules on participant loans.

Which Limit Do You Hit First?

Most investors hit the 401k wall first, because $50,000 is small next to a typical down payment. A HELOC can be much larger. The tradeoff is that your property is pledged to get it.

The crossover depends on owner profile.

• Large retirement balance, little equity. The 401k loan is the only meaningful route, and the ceiling is $50,000.
• Heavy equity, small retirement balance. The HELOC dominates.
• Both, with a rental in the picture. The investment-property ceiling of 70% CLTV and the $500,000 line cap both bind. A primary residence usually lends more.

Edge Cases Where the Rules Bend

The rental purchase term. The long repayment window applies only to a loan used to buy your main home. A 401k loan used for a rental down payment is a standard five-year loan.

Separation from your employer. An unpaid 401k loan balance can be offset when you leave. The treatment turns on plan terms and what you do next, so check the plan document before you move jobs.

Lines can shrink after approval. A lender may reduce or freeze a HELOC if the home’s value falls significantly or the borrower’s finances change. The stated limit is not guaranteed availability. Lendmire’s piece How Much a Value Drop Cuts a HELOC Limit and What an Appraisal Fixes walks through that risk.

Title. On this network, a HELOC 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 a different product such as a DSCR cash-out refinance. This is the sharpest structural difference from a DSCR loan, subject to lender program eligibility.

Property type. Single-family, 2-4 unit, PUD, townhome, and condominium properties (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agriculturally zoned properties are not.

How the Network Structures a HELOC

The network offers a standalone line in first or second lien position. Two draw structures exist on primary residences and second homes. One is a 3-year interest-only draw followed by a 17-year repayment. The other is a 5-year draw followed by a 25-year repayment. Tennessee shortens both. Investment lines run the 5-year draw and 25-year repayment structure only.

Three more mechanics matter:

• At least 75% of the line is drawn at closing. This is closer to a funded loan than a flexible reserve.
• Pricing floats through both the draw and the repayment period. It never converts to a fixed structure.
• A line of $500,000 or less ordinarily runs on automated valuation. A full appraisal is required above $500,000, and a borrower may request one at any size.

Debt-to-income tops out at 50%, or 45% for credit profiles from 600 to 679. Qualification is measured on the interest-only payment calculated on the maximum draw. That is stricter than it sounds, because the test assumes the full line is used.

The minimum credit score is 600 on a primary residence, 640 on a second home, and 700 on an investment property. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible. Seasoning on bankruptcy is 4 years from discharge or dismissal. Availability is limited to Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That footprint is narrower than the DSCR platform, which covers 41 markets including Washington, D.C.

What Happens When the Cash Goes Into a DSCR Purchase?

A DSCR purchase reads the rental’s income against its own payment. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC or 401k loan is a separate question: where did the down payment come from?

Across the network, the picture looks like this:

• Purchases land at 75%-80% LTV on most files. Select programs reach 85% LTV with roughly a 700+ score.
• A cash-out refinance on a standard rental tops out around 75% LTV, with about 6 months of seasoning commonly expected. The ceiling on short-term-rental cash-out is 70%.
• Coverage of 1.00 is where select programs start. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Credit floors run from 620 in parts of the network to around 660 for most programs. A 700+ score unlocks the strongest leverage tiers.
• Reserves vary by lender, leverage, and transaction type, commonly around 6 months of PITIA.

Whether a purchase lender accepts borrowed funds as a down payment varies by program. Some lenders will not take a down payment funded entirely by borrowed money. Down payment and reserves are also separate tests, so a HELOC draw that covers the down payment still leaves the reserves question open. A 401k loan is usually not a credit-report item, while a HELOC adds a liability that the DSCR lender will see.

Clearing 1.00 coverage is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside that number. Adding a new monthly obligation from borrowed down-payment funds tightens real cash flow even when the ratio still clears. Lendmire’s complete DSCR loans guide covers how the ratio is built.

Which Should an Investor Choose?

The right choice depends on which risk the investor can carry.

A 401k loan costs nothing in collateral. It can be repaid to yourself through payroll, and it usually requires no credit pull. The ceiling is low, the term is short, and the money leaves the market while the loan is outstanding. A job change can trigger repayment pressure.

A HELOC lends more, but it puts the property at risk, and on a rental the ceiling is 70% CLTV. Much of the line is drawn at closing, so interest begins on most of it right away.

Neither is the stronger choice for everyone. If the investor has low equity and a modest plan balance, the better move may be a smaller purchase or a different leverage structure. Going the other way, with deep equity on a primary residence and strong credit, a HELOC may fund the whole down payment, subject to the purchase lender’s treatment of borrowed funds.

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.

Key Terms Defined

CLTV: Combined loan-to-value is all mortgage and line balances added together and divided by the property’s value.

Vested balance: The portion of a retirement account that is fully yours, which always includes your own deferrals.

Draw period: The stretch when you can borrow from the line, usually paying interest only.

Repayment period: The stretch after the draw ends, when the balance amortizes fully.

Deemed distribution: A plan loan that breaks the rules and becomes taxable income.

DSCR: Debt service coverage ratio is the property’s rent divided by its monthly PITIA.
