How a HELOC Works or Home Equity Loan on a Primary Home

How a HELOC Works or Home Equity Loan on a Primary Home

The Quick Read: A home equity loan pays out one lump sum with a fixed payment schedule, while a HELOC is a revolving line you draw from during a set window. Both sit against the home you live in, and both put that home at risk if you stop paying. On Lendmire’s network, only a primary-residence line can run above $500,000, up to the $750,000 maximum.

  • A home equity loan is a second mortgage with its own separate payment, per the CFPB’s home equity guide.
  • A HELOC lets you borrow, repay, and borrow again during a draw period, then moves into repayment.
  • On the network Lendmire brokers, primary-residence lines reach 90% CLTV only at a 720 or better credit profile.
  • Lines run $25,000 to $750,000, and anything above $500,000 is primary-residence only.
  • Investment-property lines stop at 70% CLTV, so the home you live in is the stronger collateral.

Why would an investor tap a primary home at all? The equity in a primary home is often a more affordable pool of capital they own, and a rental down payment is where many want to spend it. This guide covers the mechanics, then the places where the general rule bends. Lendmire arranges these lines through select wholesale partners and is never the lender. Every figure below is subject to lender guidelines and full file review.

Editable Equity Scenario

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.



70%Max combined LTV, this tier
$500K maxLine cap, this tier

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.

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.


What Is Home Equity, and How Do Lenders Count It?

Equity is the home’s value minus what you owe on it. A home worth $500,000 with a $300,000 first mortgage has $200,000 of equity. Lenders do not let you borrow all of it.

The measure that matters is combined loan-to-value, or CLTV. It adds every loan secured by the property and divides by value. The CFPB guide notes that lenders typically want the borrower to keep a cushion of equity, commonly 10% to 20% of the home’s value.

On the network Lendmire works with, the ceiling depends on credit tier. A 720 or better profile can reach 90% CLTV on a primary residence, up to a $500,000 line. A 700 profile reaches 85% up to $500,000. A 640 profile tops out at 80%, and a 620 profile at 70%. The floor is a 600 score, which supports 60% CLTV.

Each step down in credit tier takes a visible bite out of the borrowing room.

How Does a Home Equity Loan Work?

A home equity loan is a closed-end second mortgage. You receive the full amount at closing and begin repaying principal and interest on a fixed schedule. There is no draw period and no redraw.

That predictability is the product’s main selling point. You know the obligation from day one. The tradeoff is rigidity. If you borrow too much, you pay on all of it. If you need more later, you apply again.

The CFPB guide frames it as a new mortgage with the home as collateral. If the home is already paid off, the new loan becomes a first mortgage on the property. Most borrowers still carry a first mortgage, so the new loan sits behind it.

A lump sum fits a known, one-time cost. A rental down payment is a decent example, because the number is fixed before you shop.

How Does a HELOC Work?

A HELOC is a revolving line of credit. You draw what you need, repay it, and draw again up to the limit. Payments during the draw window are typically interest-only on the balance you have drawn, and the pricing floats.

That floating structure is the part borrowers underestimate. Bankrate’s HELOC calculator page explains that HELOC pricing is variable, that lifetime caps usually apply, and that the payment can step up sharply once the draw period ends and amortization begins.

Here is the lifecycle in three phases:

1. Application and closing. The lender values the property, checks credit and debt load, and sets the limit.

2. Draw period. You borrow against the line and pay interest on what you use.

3. Repayment period. Borrowing stops, and principal plus interest come due on a fixed schedule.

On Lendmire’s network, a primary-residence line comes in two draw structures. One runs a 3-year interest-only draw followed by a 17-year amortizing repayment. The other runs a 5-year draw followed by a 25-year repayment. Tennessee shortens the repayment on each: the 3-year structure repays over 12 years, and the 5-year structure over 10. Pricing floats across both phases and never converts to fixed.

One more detail matters for planning. At least 75% of the line is drawn at closing on both structures. So a network line behaves less like a standby reserve and more like a mostly-funded loan with a small flexible remainder. The minimum draw after closing is $1,000, except in Texas at $4,000.

Home Equity Loan vs. HELOC: Side by Side

Factor Home Equity Loan HELOC
Payout One lump sum Draw as needed
Rate type Usually fixed Floating
Payment pattern Fixed from day one Interest-only, then amortizing
Best use One known expense Phased or uncertain costs
Main risk Overborrowing Payment jump after draw ends

Notice that the network line described above blends the two. Borrowers who want a true fixed payment should compare a fixed-rate second mortgage elsewhere.

What Changes When the Collateral Is a Primary Home?

Occupancy sets the ceiling. The CFPB guide says the borrower must live in the home and keep paying property taxes and homeowners insurance. In return, a primary residence earns the strongest terms.

Occupancy Max CLTV Notes
Primary residence 90% (720+ credit only) $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program)
Second home Up to 90% (720+ credit only) 640 minimum score
Investment property 70% 5-year draw, 25-year repayment only

A few primary-residence specifics stand out:

  • At 720 or better, you choose between 90% CLTV up to $500,000 or a larger line up to $750,000 at a reduced 75%.
  • A line above $500,000 requires a 700 or better credit profile (720 on the longer 5-year-draw structure), caps at 75% CLTV, and needs a full appraisal.
  • Lines at or below $500,000 ordinarily use automated valuation, though a higher CLTV may require a second valuation.
  • Maximum debt-to-income is 50%, and 45% for scores from 600 to 679. The lender reviews your file on the interest-only payment at the maximum draw.

Title matters here too. The borrower must hold title personally or through a revocable living trust. An LLC, a corporation, or an irrevocable trust cannot hold title on these lines. That is the sharpest difference from a DSCR loan, which commonly closes in an entity name, subject to program guidelines.

Eligible property types include single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable ones. Manufactured homes, co-ops, condotels, and log homes are not eligible.

Key Terms Defined

CLTV: Combined loan-to-value, the total of all liens on the property divided by its value.

Draw period: The window when you can borrow from a HELOC, usually with interest-only payments.

Repayment period: The phase after the draw ends, when principal and interest are both due.

Lien position: Whether a loan is paid first or second if the property is sold or foreclosed.

Cross-collateralization: Using one property, here your home, to secure money spent on another.

How Does Underwriting Actually Treat a Line on Your Home?

Underwriting follows a short sequence, and each step can stop the file.

1. Credit. The network uses 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 floor is 600.

2. Housing and credit history. Depending on the program, expect tradeline and mortgage-payment standards applied across all financed properties.

3. Debt load. The lender calculates DTI using the interest-only payment on the full line.

4. Value. An automated valuation or full appraisal sets the CLTV math.

5. Title and property check. Vesting, property type, and occupancy are confirmed.

Derogatory events carry real weight. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history splits by program on primary residences. One program seasons a foreclosure at 7 years and a deed in lieu, pre-foreclosure, or short sale at 4. The other declines that history entirely, regardless of age.

Business bank accounts for deposit analysis require a 680 minimum. A borrower at 640 clears the 600 floor and so can qualify for the line itself, yet cannot use business accounts to document income. That is a real gate for self-employed investors.

Exposure caps apply as well. A borrower may hold three lines, with combined exposure capped 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. Large portfolios hit this wall.

Where the General Rule Breaks

The standard picture is a borrower with one home, one first mortgage, and a clean file. Several situations bend it.

Texas. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. The higher matrix tiers never apply. A 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning bind primary residences only. Texas second homes and investment properties are eligible as non-homestead transactions. Properties are limited to 10 acres. Lendmire’s piece Texas Home Equity Loan and HELOC Limits for a Primary Home covers that state in detail.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.

Credit-dependent caps. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.

Sub-640 borrowers. Under the longer-runway program, these profiles are limited to single-family residences with a clean 12-month housing history. Because second homes floor at 640 and investment properties at 700, that restriction reaches primary residences only.

Entity-owned homes. If the property is already deeded to an LLC, it needs a vesting change first. A DSCR cash-out may fit better.

Availability. These lines are offered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the 41-market DSCR footprint.

The Investor Decision in Practice

Picture an investor with a primary home carrying meaningful equity and a rental target in view. The line on the primary home funds the down payment. The rental then needs its own financing.

That is where the two products meet. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The line on your home is a separate obligation. Whether a DSCR lender accepts borrowed funds for the down payment or reserves is a program question, and it is worth settling before you sign anything. The complete DSCR loans guide covers the rental side.

On the DSCR side, many select programs start at a 1.00 coverage ratio. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Clearing 1.00 only means rent covers the payment. It does not mean positive cash flow, because repairs, vacancy, management, and utilities sit outside the ratio.

Here is the stress test that matters most. Your home now carries two obligations: the first mortgage and the line. The rental must carry its own debt, and you still need to cover the line payment from other income. One investor discussion on BiggerPockets notes that HELOCs on investment property exist at some banks but are limited to a smaller set of lenders. That is why many investors turn to the primary home for the line instead.

Three scenarios show how the choice flips:

  • A single known cost. A lump-sum down payment points toward the fixed-schedule second.
  • A phased renovation. Staged repairs on a first rental favor a line you can draw over time, though the 75% drawn at closing on network lines reduces that flexibility.
  • Debt consolidation ahead of a DSCR purchase. Paying down personal debt can improve your DTI and credit profile before the rental loan, but it ties your home to that debt.

When Neither Product Fits

Skip both if the numbers only work at maximum leverage. A line on your home at 90% CLTV leaves almost no cushion if values dip. Lenders can reduce a line when the home’s value falls, so the available credit is not guaranteed.

Alternatives exist. A cash-out refinance on the primary home replaces the first mortgage instead of adding a second. A DSCR cash-out on an existing rental taps equity in the investment itself, with the rental as collateral rather than your residence. If you own the rental free and clear, that route keeps the risk off your home. The DSCR cash-out refinance page covers how that works.

Cross-collateralizing is the real cost. When your home secures the money that buys the rental, a failed rental can threaten the roof over your head. A line on the rental itself caps the damage at the rental, but it comes with the 70% CLTV ceiling.

Frequently Asked Questions

Can I use a HELOC on my primary home for a rental down payment?

Often yes, but the rental lender decides whether borrowed funds count. Whether a DSCR program accepts line proceeds as a down payment or reserves, and whether the line payment enters the file, depends on the program. Confirm that first. The transaction trail from the line to closing should be clean and documented.

How much can I borrow on a primary residence?

Lines run $25,000 to $750,000. At 720 or better, you can reach 90% CLTV up to $500,000, or 75% CLTV up to $750,000. Lower credit tiers carry lower ceilings. Every figure is subject to lender guidelines and a full file review.

Does a primary residence line need an appraisal?

Not always. Lines at or below $500,000 ordinarily use automated valuation, though a higher CLTV may require a second valuation. Anything above $500,000 requires a full appraisal. You can also request one in any case.

Will the rate stay the same for the life of the line?

No. Pricing floats through both the draw and repayment periods on network lines and never converts to fixed. Payments can step up when the interest-only draw ends. Budget for the higher amortizing obligation before you borrow.

Can an LLC borrow against my home?

No. Title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title on these lines. Entity-owned properties need a vesting change first, or a DSCR cash-out may be the better fit.
