Where to Get a HELOC for a Large Credit Line Above Conforming Limits

The Quick Read: A conforming loan limit does not cap a home equity line. The line size comes from each lender’s own dollar ceiling and combined loan-to-value test. Large lines are scarce, and they are easier to find on a primary residence than on a rental. Lines above $500,000 are the hardest to place of all.

• The conforming limit only governs which first mortgages Fannie Mae and Freddie Mac may buy. It does not set a HELOC ceiling.
• Through Lendmire’s network, an investment-property line tops out at 70% CLTV and $500,000, with a 700 minimum credit profile.
• The maximum line on a primary residence is $750,000, and any line above $500,000 is primary-residence only, capped at 75% CLTV, and needs a full appraisal.
• The title must sit with an individual or a revocable living trust, not an LLC.
• A DSCR cash-out refinance is often the better fit for large rental equity, since it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Does the Conforming Limit Cap a HELOC?

No. The conforming limit is the largest first mortgage that Fannie Mae and Freddie Mac may acquire. For 2026, the baseline limit for a one-unit property is $832,750, and in high-cost areas it reaches $1,249,125. Those numbers describe what the two agencies can purchase. They say nothing about what a bank or credit union will lend on a second lien.

A HELOC has its own ceiling. Each lender sets a maximum line and a maximum combined loan-to-value ratio. The line you receive is the lesser of the two results. A property with huge equity can still be capped by a product’s dollar limit.

Here’s where the conforming number does matter. If the HELOC sits behind a large first mortgage, the first loan may be conforming in one county and jumbo in another. That affects the first lien’s terms. It does not change the line you can open behind it.

How Underwriting Treats a Large Line, Step by Step

A HELOC is an open-end line you borrow against repeatedly during a draw period, followed by a repayment period. Underwriting runs in a fixed order.

1. Eligibility gates. Occupancy, property type, and how title is held come first. Many lines fail here, before credit or equity is even reviewed.

2. Equity and CLTV. The CFPB’s HELOC booklet describes the common method: take a percentage of appraised value, then subtract the existing mortgage balance. In formula form, value times the maximum CLTV, minus existing liens.

3. Credit and debt-to-income. A HELOC is underwritten on the borrower. Rent coverage is not the test. On Lendmire’s network the DTI cap is 50%, and 45% for credit profiles from 600 to 679.

4. Valuation. Lines at or below $500,000 usually use an automated valuation, though a higher CLTV may call for a secondary valuation. Every line above $500,000 needs a full appraisal, and a borrower may request one on any line.

5. Closing and draws. A large share of the line is drawn at closing on the wholesale programs we place, and later draws carry minimums.

What the Network Actually Offers

Lendmire is a broker. It arranges home equity lines through select wholesale partners, in the 16 states where it offers full-service lending. Two wholesale programs sit behind the line product, and their terms differ in places. Both are standalone lines in first or second lien position, with floating pricing that never converts to fixed.

Primary-residence leverage steps down with credit. A 720 profile reaches 90% CLTV on lines up to $500,000. A 700 profile reaches 85% at that size. Above $500,000, the line requires 700 or better (720 on the longer-runway program, the one with the five-year draw and 25-year repayment), caps at 75% CLTV, and needs a full appraisal.

Second homes have a 640 floor and a 90% ceiling that exists only at 720. Their maximum line is $500,000, while primary residences can reach $750,000 and accept lower credit profiles, down to 600.

Where the General Rule Breaks

Several edge cases decide whether a large line is possible at all.

LLC title. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change or a different product. This is the sharpest difference from a DSCR loan, where entity ownership is common, subject to lender program eligibility.

Primary-residence lines funding rentals. The only way to reach $750,000 is against an owner-occupied home. That works as a funding source for acquisitions, but check the line’s occupancy and use terms first. Renting out the home securing the line may be prohibited under its terms.

Portfolio size. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. Owning more than 15 financed properties makes a borrower ineligible.

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

Free-and-clear rentals. A HELOC can be the only lien. A property with no mortgage still works, within the investment ceiling.

Which Lender Type Fits a Large Line?

One BiggerPockets thread notes that many lenders do not offer HELOCs on rentals at all, and points investors toward the servicer of their first mortgage, nearby banks, and credit unions.

A broker sees many programs’ guidelines at once, so the useful question is which program’s gates your file clears, not which brand name to call first.

HELOC, Cash-Out Refinance, or Both?

A HELOC and a DSCR cash-out refinance solve different problems. A HELOC fits the investor with strong personal income, low DTI, and a property titled in their own name. Because it is underwritten on the borrower, each new financed property eats into DTI, which is why growing portfolios find lines harder to get. One investor in a BiggerPockets discussion described using a line to speed acquisitions, then refinancing to repay it.

A DSCR cash-out refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across most of the network, cash-out refinances top out around 75% LTV on standard rentals, with about six months of seasoning commonly expected. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and entity ownership is usually workable, subject to program terms. For equity above $500,000 on a rental, or any rental held in an LLC, that is typically the practical route. The complete DSCR loans guide covers how coverage ratios, leverage, and credit tiers fit together.

Clearing a 1.00 coverage ratio is not the same as positive cash flow. DSCR compares rent to the full monthly payment only. Repairs, vacancy, management, and capex sit outside the number.

Planning a Very Large Line

Floating pricing is the main structural risk. HELOCs usually carry adjustable rates, and lenders can reduce a line if the property’s value falls. The network’s lines draw interest-only for three or five years, then amortize over the remaining term, so the payment steps up at the end of the draw period. Qualification uses the interest-only payment on the maximum draw.

Plan the draw around a defined use. A line used as a bridge to buy a rental works best with a clear exit, like a later refinance. A line left open as permanent leverage carries the repayment step-up and variable-payment exposure the whole time.

• What is the combined LTV ceiling for my occupancy type and credit tier?
• At what line size does the lender require a full appraisal?
• How much of the line must I draw at closing, and what are later draw minimums?
• Is there a limit on how many lines or how much combined exposure I can hold?
