Banks That Offer a HELOC for Buying Your Third Property

The Quick Read: Few banks write an equity line against a rental, so the realistic route is a line secured by your primary home, or by a rental held in your own name, that you draw at closing and use as the down payment on a separate DSCR purchase loan. You repay that line from your own cash flow, not from the new property’s rent.

• A line on a primary residence reaches much higher combined leverage than a line on a rental.
• On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score.
• The borrower must hold title personally or in a revocable living trust. LLC-titled properties are out.
• A DSCR purchase loan looks at the new property’s rent against its own payment. The line sits outside that ratio but inside your personal debt-to-income (DTI) ratio.
• The right program depends on your equity, credit, property type, and how many financed properties you already own.

Who Actually Offers a HELOC When You Are Buying Property Number Three?

Equity lines on rentals come from a small slice of the lending market, and the answer changes with the lender type. NerdWallet notes that for rental properties you may have a smaller pool of lenders and borrow less than against your primary home. It adds that the product isn’t offered by all lenders and carries strict qualification requirements.

This article does not name or rank any lender, because the lender that fits depends on your file. Here is how the categories tend to behave.

Lendmire is a mortgage broker, not a lender. It places equity lines through a network of wholesale HELOC lenders and matches your property, equity, and credit to a program. That route is available in Lendmire’s 16 full-service states, a narrower footprint than its DSCR investor lending across 41 markets, including Washington, D.C.

How Does Underwriting Treat a Line Used for a Third Purchase?

Underwriting treats the line as a personal loan secured by property. Qualification rests on your credit, your income, and your total debts, not on the rent from the home you plan to buy. The steps run in a fixed order.

1. Pick the collateral. The line can sit in first or second lien position on your primary home, a second home, or a rental you hold personally. Equity left after any first mortgage sets your capacity.

2. Value the property. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal, though a higher CLTV can trigger a secondary valuation. You can also request a full appraisal. Rental collateral may call for multiple appraisals.

3. Test credit and DTI. The network’s maximum DTI is 50%, and 45% for credit profiles between 600 and 679. A ratio above 45% requires at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, even if you plan to use less.

4. Draw the cash. At least 75% of the line is drawn at closing. Pricing floats during the draw and repayment periods and never converts to fixed.

5. Buy the property on a separate loan. The DSCR lender will ask where the down payment came from, and borrowed funds may not count toward reserves.

6. Plan the repayment. After the interest-only draw ends, principal repayment starts.

The CFPB describes how a HELOC works: a revolving line with a draw period that can last 10 years, usually at a variable interest rate. Network structures are shorter and vary by occupancy, as covered below.

The third-property effect lives in step 3. Two mortgages already sit in your DTI. Every financed property counts, and a borrower with more than 15 financed properties is not eligible for these lines. A borrower is also limited to three lines in total, with combined exposure capped by program.

Which Property Should Secure the Line?

Occupancy sets the ceiling, and the ceilings differ sharply. The primary home often offers the wider range of terms.

On a primary residence, 90% CLTV exists only at a 720-or-better credit profile, and it applies to lines up to $500,000. The tiers below that step down: 700+ reaches 85% on a line up to $500,000, 680+ and 660+ also sit at 85%, and 640+ is 80%. Lower scores step down further. On an investment property, both the 720+ and 700+ tiers cap at 70% CLTV. A second home sits between the two, with a 90% ceiling at 720+ and a 640 minimum score.

The draw structures work like this. One structure runs a 3-year interest-only draw, then a 17-year fully amortizing repayment. The other runs a 5-year draw, then 25 years of repayment. Investment lines use only the 5-year draw and 25-year repayment version. A quoted figure always belongs to its own structure.

Eligible collateral includes single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. A property listed for sale, or listed within the past 60 days, is ineligible in some states.

A Worked Example: Equity to Down Payment to Purchase

Picture an investor with a primary home and two rentals, shopping for a third. The primary home carries a first mortgage that leaves combined leverage near 60% of value. With a 720+ score, a line on that home can reach up to 90% CLTV, so room exists, up to the line limit. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Now run the same investor with the line secured on a rental. The ceiling drops to 70%. If that rental’s first mortgage already sits near 60% of value, only a thin slice remains. The investor would likely secure the line on the primary home instead.

Next comes the purchase. Most DSCR purchase files land at 75% to 80% LTV, so the down payment is 20% to 25%. A select program reaches 85% LTV with roughly a 700+ score. The investor draws from the line and puts that cash into the purchase. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

Suppose the new rental clears roughly 1.2x coverage. That means rent covers the full payment, which includes principal, interest, taxes, insurance, and any HOA dues, with some cushion. That ratio is the lender’s test of the new property. It does not mean the investor has positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside DSCR. The line payment is not in that ratio either. The Yahoo Finance explainer on using a line for a down payment notes funds can cover the down payment, closing costs, or other expenses up to the approved limit.

The practical risk is stacking. If you borrow nearly all the down payment on top of high-leverage purchase financing, you end up financing close to the whole price. A purchase lender may scrutinize that, and your three obligations (first mortgage, line, new loan) all come out of your own cash flow.

Key Terms Defined

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

CLTV (combined loan-to-value): All loans secured by the property added together, divided by its value.

DSCR (debt service coverage ratio): Monthly rent divided by the monthly payment of principal, interest, taxes, insurance, and HOA dues. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

DTI (debt-to-income ratio): Your monthly debt payments divided by your monthly income. A line is judged on this; a DSCR loan is not.

Seasoning: The waiting period a lender wants after an event, such as owning a property for about six months before a cash-out refinance.

Vesting: How title to a property is held, whether personally, in a trust, or in an LLC.

Where the General Rule Breaks

The rule is that a line on your own property funds your next purchase. Several edge cases break it.

LLC title. Individuals and revocable living trusts can hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot. This is the sharpest difference from DSCR lending, where LLC borrowers are common, subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change before it can secure a line, or a DSCR cash-out refinance instead.

A rental with an existing mortgage. The line goes in second position behind the first lien, so only the equity left over counts. Many lenders decline that position on non-owner-occupied collateral entirely.

Naming. Some lenders decline anything called a HELOC on a rental but offer a similar line under another product name. Ask what the product is, not just what it is called.

Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On primary residences and second homes, one program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4, while the other declines that history entirely. Investment files follow the 7-and-4-year path.

Single-bureau scoring. The score model is keyed to the primary wage earner, and the report can be no more than 90 days old at closing. Rescores are not available.

Variable cost. The CFPB notes HELOC rates are usually variable, so payments can change. When payments rise, a rental’s cash flow can erode.

Foreclosure exposure. Benzinga points out that failing to make payments on a line risks foreclosure on the investment property. The pledged property is at risk even when the cash goes toward a different one.

HELOC or DSCR Cash-Out: Which Fits Your Third Purchase?

Neither route is automatically better. A line suits an investor with a primary home, strong credit, and a clean personal DTI. A DSCR cash-out suits someone whose equity sits in an existing rental.

On the DSCR side, 1.00 coverage is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Most programs want a score near 660, and 700+ opens the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA (principal, interest, taxes, insurance, and HOA dues).

Some investors combine the two: draw on a line for the down payment, buy with a DSCR loan, then later pull equity out of a seasoned rental with a cash-out refinance to pay the line down. That plan only works if the rental’s cash flow can carry the interest-only line in the meantime. The complete DSCR loans guide covers the loan side in full. Lendmire’s piece Banks That Offer an Investment Property HELOC for Investors Buying More Rentals goes deeper on the scaling question.

How Do You Screen Lenders and Prepare the File?

The lenders that write these lines depend on your property type, credit profile, and title. Before you apply anywhere, ask five questions:

• Do you write lines on non-owner-occupied property?
• Do you allow second-lien position behind my existing mortgage?
• Must title be personal, or is a revocable trust acceptable?
• How do you count my existing financed properties in DTI?
• What is the draw structure, and does pricing float?

Then gather your documents. Expect a credit report, income documentation, mortgage statements on every financed property, proof of title and vesting, and the purchase contract for the third property. If you plan to use a line as a down payment, expect to document the draw and the deposit trail.

A broker that shops several wholesale lenders can run this screen for you. It is useful when your property or title does not fit a single lender’s box.

Next Step

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals.

A line gets you the down payment, but the third property still has to earn its keep on its own.
