Investment Property HELOC Lenders to Buy Another Home

The Quick Read: A home equity line does not buy the next property; it supplies cash that you then use as a down payment on a separate purchase loan, and the lenders that write lines against a rental are fewer, stricter, and more equity-focused than those that write lines against a primary home. Lendmire is a mortgage broker, so it matches your file to a wholesale partner rather than lending itself. The best program for your situation depends on the property, the equity, and your credit.

• On an investment property, the network’s ceiling is 70% of the property’s value across all loans on it (combined loan-to-value, or CLTV), with a 700 minimum credit score and a line of up to $500,000.
• On a primary residence, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile.
• The line must be titled to you personally or to a revocable living trust. An LLC cannot hold title.
• A DSCR purchase loan judges the new property’s rent against its own payment, so the line’s payment generally sits outside that ratio. It still hits your real cash flow.

What Does a HELOC Actually Do in a Purchase?

A HELOC (home equity line of credit) is a revolving credit line secured by the equity in a property you own. It is not a purchase loan. It supplies cash, and the cash goes into a separate purchase, usually as a down payment on a DSCR loan, a conventional loan, or an all-cash offer.

DSCR stands for debt service coverage ratio. It compares the new property’s rent to that property’s own monthly payment. That is why the two products pair well: the line is underwritten on you and your equity, and the purchase loan is underwritten on the rental.

You have two choices for collateral. You can put the line on your primary home, or you can put it on a rental you already own. Many lenders write lines on primary homes. Far fewer write them on rentals, and the ones that do apply tighter limits. A broker that shops several wholesale lenders can compare those limits side by side, which a single bank cannot do for you.

How Investment Property HELOC Lenders Underwrite a Line, Step by Step

Underwriting a line is about you and the equity, not the future rental. Here is the sequence across the wholesale programs Lendmire works with, subject to lender guidelines.

1. Occupancy and collateral. The lender first asks what the line will sit on. A rental gets the investment-property table. A primary home gets the owner-occupied table, which allows more leverage.

2. Combined leverage. The lender adds the existing first mortgage and the new line, then divides by the property’s value. On an investment property, that combined figure stops at 70% CLTV. Say your rental has a first mortgage at 50% of its value. The most the line could add is roughly 20% of value, and that figure is a ceiling on the line, not a promise of what you will be approved for. Other limits apply on top of it.

3. Credit. Investment lines require a 700 minimum. On an investment line, 700 and 720 both reach the same 70% ceiling, so a higher score buys eligibility, not more leverage. The primary-home table works differently, with its top ceiling reserved for 720-or-better profiles. The lender uses a single-bureau score tied to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.

4. Debt-to-income (DTI). Maximum DTI is 50%. The lender reviews your file on the interest-only payment calculated as if the line were fully drawn, so unused room still counts against you.

5. Valuation. An investment line tops out at $500,000, and the full-appraisal requirement applies to lines above $500,000. So an investment line is commonly valued by an automated model with no traditional appraisal. A higher CLTV may trigger a second valuation, and a borrower may request a full appraisal in any case.

6. Property and title review. The collateral must be an eligible property type, and the title must sit in an eligible name. Both are covered below.

Notice what is missing: the rental’s income does not drive the line. Equity, credit, and DTI do. The DSCR test comes later, at the purchase loan.

Rental-Secured Line, Home-Secured Line, or DSCR Cash-Out?

Each route pulls equity differently. The table compares them on network figures, each subject to lender guidelines and file review.

The cash-out column works differently from the other two. A DSCR cash-out refinance replaces your existing first loan, and the new loan must be supported by the property’s rent. About six months of seasoning is the common expectation, meaning a waiting period since you bought or last refinanced.

A line keeps your current first mortgage intact. That matters when the existing loan carries terms you want to hold on to. The trade is that the line’s pricing floats during both the draw and repayment periods and never converts to fixed. A cash-out refinance can be structured on a 30-year fixed spine, with extended terms and interest-only periods available through select lenders.

Where the General Rule Breaks

The line is mostly drawn at closing. A common idea is to open a line and leave it undrawn as a standby reserve. On these programs, at least 75% of the line is drawn at closing. Investment lines also use one structure: a 5-year interest-only draw period followed by a 25-year fully amortizing repayment. Plan the line around cash you intend to use now.

Lines can be frozen. The Federal Trade Commission notes that a lender can freeze or reduce a line if the home’s value falls significantly or if it reasonably believes your finances have changed enough to endanger repayment. Do not count on undrawn availability as a reserve.

Selling or renting the collateral. The CFPB’s HELOC booklet says that if you sell the home, you are generally required to repay the line in full. It also warns that the line’s terms may prohibit renting out the home that secures it. Read the agreement before you convert a property to a rental.

LLC-owned property. Title must be held by you as an individual or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title, subject to program terms. This is the sharpest structural difference from a DSCR loan, which can close in an entity name depending on program guidelines. A rental already deeded to an LLC needs a vesting change before a line is possible. Otherwise a DSCR cash-out is the cleaner route.

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

Borrower limits. A borrower is limited to three lines in total. A borrower who owns more than 15 financed properties is not eligible. Past bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure follows a 7-year seasoning path, and a deed-in-lieu, pre-foreclosure, or short sale follows 4 years.

Self-employed borrowers. The file is reviewed on documented income under the applicable program, subject to lender guidelines. A business bank-statement deposit analysis needs a 680 minimum. Investment already floors at 700, so documentation style is never the binding limit on an investment line. Credit and equity are.

Where the broader market differs. White Coat Investor reports that investor-education sources commonly cite rental HELOC standards of a 720 credit score, 6 months of reserves, 20% equity remaining, 50% DTI, and an 80% loan-to-value cap. Those are market-wide figures. The network’s investment ceiling is 70% CLTV with a 700 minimum, and the network ceiling is the one that applies to a Lendmire placement.

The Purchase Workflow, Start to Finish

Sequence matters more than most borrowers expect. Here is how the pieces fit when the line funds a down payment.

1. Check eligibility first. Confirm the property, title, equity, and credit against the program. Also confirm that the HELOC’s state availability covers you. Lendmire places lines only in its 16 full-service states, a narrower footprint than its 41-market DSCR coverage.

2. Ask the purchase lender about borrowed funds. Whether a purchase lender accepts HELOC-sourced down-payment money depends on the program and its guidelines. Ask before you draw.

3. Open the line and draw. Because most of the line is drawn at closing, size it for the cash you need. Then keep the draw documented through the line statement and your bank statements.

4. Close the purchase loan. For a DSCR purchase, most files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV, roughly 15% down, with about a 700+ score. Credit expectations vary: a 620 floor exists in parts of the network, most programs want around 660, and 700+ opens the strongest leverage tiers.

5. Carry both payments. The purchase loan is covered by rent. The line’s interest-only payment during the draw period is a personal obligation. Plan where it comes from.

6. Repay or refinance. The line moves from interest-only to fully amortizing at the end of the draw. Many investors plan an exit before that, such as paying it down from cash flow or a later DSCR cash-out on the rental.

A Worked Example With Ratios Only

Run the numbers on this modeled scenario. These are assumptions, not market data. You buy a rental with 25% down on a DSCR loan at 75% LTV. A line on your primary home funds the entire 25%. That line would sit on the primary-residence table, and the assumption is a credit profile of 720 or better, which is the only tier where the 90% CLTV ceiling applies. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

The new property’s rent covers its own full monthly obligation at roughly 1.2x. Your DSCR reads 1.2x because the ratio looks only at the new loan. Across the two loans, your financing comes to close to 100% of the purchase price.

DSCR compares rent to PITIA only. PITIA means principal, interest, taxes, insurance, and any association dues. A 1.2x result means rent clears the payment by about 20%. It does not mean the property cash flows. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation, and so does the line’s payment.

Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A larger down payment lowers the new loan and can lift the ratio. It does not erase leverage caps, credit floors, reserve rules, or property eligibility.

Reserves vary by lender, leverage, loan size, and transaction. They are commonly around 6 months of PITIA, with conservative files at modest leverage sometimes seeing them waived. Ask whether borrowed funds can count toward reserves. That also varies by program.

How to Screen Lenders Before You Apply

Since lenders differ more than their marketing suggests, a short checklist saves effort. Ask each one:

• Does the program write lines on non-owner-occupied rentals, and what is the investment CLTV ceiling?
• Is the line a first or second lien, and does it work behind my existing mortgage?
• What is the draw and repayment structure, and how much must be drawn at closing?
• Will the line be valued by an automated model, or does it require an appraisal?
• Does my title (individual, trust, or LLC) fit program requirements?
• Will my DSCR purchase lender accept this line’s proceeds for the down payment?

The lenders that write these lines depend on your property type, credit profile, leverage need, and documentation. A broker that works with multiple wholesale lenders can match the scenario to the program instead of sending you door to door.

What Are the Real Risks?

The line is personal debt. Its pricing floats and never converts to fixed. When it sits on your primary home, you are putting your residence behind a business purchase. When it is the whole down payment, the investor is effectively financing close to the full purchase price.

When to Choose Something Else

A line is not always the right tool. Consider alternatives in these cases:

• Your credit is under 700 or your property is in an LLC. A rental-secured line is likely off the table. A DSCR cash-out refinance can work when rent supports the larger loan. Select lenders in the network offer programs below 1.00 coverage, with leverage and terms adjusted.
• You want to leave the first mortgage alone but have thin equity. The 70% CLTV ceiling may leave too little room. Cash savings may be the cleaner source.
• You are uncomfortable with a floating personal payment. A DSCR cash-out refinance keeps the debt property-level, with a 30-year fixed spine available.

DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The complete DSCR loans guide covers how that review works.

Key Terms Defined

Draw period: the stretch when you can borrow against the line and pay interest only. The CFPB explains that a repayment period follows, with no further draws.

Automated valuation: a computer-generated estimate of a property’s value, used instead of a traditional appraisal on smaller lines.

Vesting: the legal name in which the property’s title is held, such as an individual, a trust, or an LLC.

Seasoning: the waiting period a lender wants between two events, such as buying a property and refinancing it.

Lien position: the order in which loans on a property get repaid, with a first lien paid before a second.
