Banks That Offer an Investment Property HELOC for Owners Keeping Their First Mortgage

The Quick Read: A broker can place a second-position line behind your existing first mortgage on a rental through wholesale lenders, though few large banks write one, and on Lendmire’s network the investment ceiling is 70% combined loan-to-value with a $500,000 maximum line and a 700 credit minimum.

• Your first mortgage stays in place. Its balance counts against the combined-leverage cap.
• The line qualifies you personally: credit, debt-to-income, and equity. It is not a rent-based loan.
• The property must be titled to you or to a revocable living trust. An LLC cannot hold title on this product.
• Everything here is subject to lender guidelines and a full file review. It is not a commitment to lend.

What an Investment Property HELOC Is

An investment property HELOC is a revolving line of credit secured by a rental you own. It sits in second position behind your first mortgage. You borrow against equity, not against rent.

Your first mortgage keeps its balance, term, and payment. Nothing gets refinanced or paid off. That is the whole appeal for an owner who holds a low-cost first loan and does not want to disturb it.

Equity is value minus what you owe. A lender sets the line by applying a percentage to the property’s value and then subtracting the first mortgage balance.

Why Few Big Banks Write This Product

Most large retail lenders keep home equity lines to owner-occupied homes. A rental carries more risk for a junior lien, so the product is thin among the biggest names. NerdWallet reports that not every lender offers a HELOC on an investment property. It also reports that some restrict eligibility by location or by whether the home is rented year-round.

Appetite lives in a few lender types. The table shows where it tends to sit.

The best fit depends on your property type, credit profile, equity, and how much you want to draw. That is why a broker that shops several wholesale lenders can save a long round of cold calls. Lendmire is a broker. It places a file with a lender whose program fits. The lender reviews and decides.

How Underwriting Treats the File, Step by Step

An equity line reads the borrower first and the property second. The steps run in this order.

1. Lien position and occupancy. The lender confirms the line goes in second position behind your first mortgage and that the property is a rental. Ownership must sit in your name or a revocable living trust.

2. Combined leverage. The lender adds your first mortgage balance to the proposed line and divides by value. On an investment property, the network ceiling is 70% combined loan-to-value. Market surveys report higher maximums at some lenders: NerdWallet cites up to 80% with many lenders lower. On this network, the investment ceiling is 70%.

3. Credit. An investment line requires a 700 minimum. Scores of 700 and 720 or higher both reach the same 70% ceiling, so credit above 700 adds eligibility, not leverage. The score model is a single-bureau pull keyed to the primary wage earner, and the report can be no more than 90 days old at closing.

4. Debt-to-income. The ceiling is 50%. The lender reviews your file on the interest-only payment calculated at the maximum draw, not on what you plan to borrow. Plan for that larger payment when you size the line.

5. Valuation. An investment line is capped at $500,000, and full appraisals are required only on lines above $500,000. An investment line therefore ordinarily uses automated valuation with no traditional appraisal. A higher combined leverage may require a secondary valuation, and a borrower can request a full appraisal anyway.

6. Documentation. Expect a lease or rent evidence, a mortgage statement for the first loan, insurance, and proof of title. Rent supports the file. It does not qualify it.

The Worked Example: Room Under the Cap

The arithmetic is simple. Room under the cap equals 70% minus your first mortgage balance as a percentage of value. These are modeled assumptions, not market data.

• A first mortgage at 45% of value leaves room of 25% of value, though the line can never exceed $500,000.
• A first mortgage at 62% of value leaves room of 8% of value. That is a thin slice, and the line may be too small to be worth pursuing.
• A first mortgage at 70% of value or more leaves no room at all.

Run this before you apply. If your first loan is already near the cap, the product cannot help you, and a different structure is the real answer.

Structures and Variations

The investment line runs one structure: a 5-year interest-only draw, then a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed. Line sizes run from $25,000 to $750,000 across the network, but an investment line caps at $500,000.

The 75% draw at closing matters for the “keep the cheap first mortgage” plan. You do not get a mostly unused standby line. You start paying on most of the balance on day one. Size the line to what you will actually use.

The CFPB describes the general HELOC shape: a draw period, then a repayment period. The line sits on top of the first loan, so you carry two payments.

Property types are single-family, two-to-four units, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.

Exposure has limits too. Lendmire places these lines with two wholesale programs: one built for higher leverage, one for a longer interest-only runway. A borrower can hold at most three lines. Total exposure across those lines is capped separately at $2,000,000 on the higher-leverage program and at $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.

Availability is narrower than the DSCR footprint. These lines are offered in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. DSCR investor loans reach 41 markets, including Washington, D.C. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.

Where the Rule Breaks

Several situations change the answer.

Entity title. An LLC, corporation, partnership, or land trust cannot hold title on this product. A rental already deeded to an LLC needs a vesting change, or it fits a DSCR cash-out refinance better, subject to lender program eligibility.

A high first-mortgage balance. If the first loan already uses most of the room, the cap leaves little to borrow. A cash-out refinance resets the whole balance and is the usual alternative.

Seasonal or short-term rentals. Some lenders restrict by whether the home rents year-round, per NerdWallet. Disclose the rental pattern up front so the file lands with a lender that accepts it.

Derogatory credit. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years. A deed-in-lieu, pre-foreclosure, or short sale needs 4.

A line the lender can reduce. A lender can freeze or cut a line if the property’s value falls. Treat the line as available credit, not guaranteed funding.

Using the home instead. Some owners draw on a line secured by their primary residence. That is a different product with different leverage tiers. Primary-residence lines can reach 90% combined loan-to-value, but only with a 720 or better credit profile. They are not an investment property line.

Tax. Tax treatment can depend on how the funds are used and how the property is held, so keep clear records and speak with a qualified tax professional before relying on any deduction.

Keep the First Mortgage or Replace It?

The decision is not about which product is better. It depends on the size of the need and the value of the first loan.

A DSCR cash-out compares rent to the full monthly obligation of principal, interest, taxes, insurance, and any dues. One select-program starting point is 1.00 coverage. A separate select-lender path goes below 1.00 with leverage and terms adjusted. Credit typically runs around 660, and cash-out generally expects about 6 months of seasoning. A 70% ceiling applies when the collateral is a short-term rental. Clearing the coverage test is not the same as positive cash flow, because repairs, vacancy, management, and capex sit outside the ratio.

The HELOC makes sense when the first loan is worth protecting, the need is modest, and your personal profile is strong. The DSCR route fits when the need is large, the property sits in an LLC, or an investor with many financed properties is pressed on personal debt-to-income. The complete DSCR loans guide covers the property-based side in full.

A second piece covers the rules for owners holding a low first mortgage.

Key Terms Defined

HELOC: A revolving line of credit secured by property equity, with a draw period followed by repayment.

Second lien: A loan that sits behind the first mortgage and is paid second if the property is sold or foreclosed.

Combined loan-to-value (CLTV): The first mortgage balance plus the new line, divided by the property’s value.

Draw period: The stretch when you can borrow against the line, here five years on an investment property.

DSCR: A ratio of rental income to the property’s monthly debt payment, used on rent-based investor loans instead of a HELOC.

Vesting: How title is held. On this product it must be an individual or a revocable living trust.

Questions to Ask Before You Apply

Ask these to screen out a bad fit early.

• Do you write lines on non-owner-occupied rentals at all?
• Will you take second position behind my current first mortgage?
• Can I hold title personally or in a revocable trust?
• What combined-leverage cap applies to an investment property?
• How much must be drawn at closing?
• Is the pricing variable through both draw and repayment?
• Can the line be frozen or reduced if value falls?
• What happens to the line if I refinance the first mortgage later?

The last question deserves a clear written answer. A later refinance of the first loan may require the line to be subordinated or paid off.
