Best Investment Property HELOC Program to Buy Another Home

The Quick Read: The right program depends on which property secures the line, how much equity sits above existing liens, and your credit and debt load; on an investment property, the lenders Lendmire works with top out at 70% CLTV and $500,000, and the line funds the down payment while a separate DSCR loan buys the new rental.

• A HELOC (home equity line of credit) turns equity into cash for a down payment and closing costs. It cannot cover the whole purchase.
• Two separate approvals happen. The line is judged on you and your equity. The purchase loan is judged mainly on the new property’s rent.
• On an investment property, the line caps at 70% CLTV and $500,000, and 700 is the minimum credit score.
• Clearing the DSCR test on the new property does not mean the deal cash flows. The line payment still comes out of your bank account.

Why “Best” Means Best Fit

No single product wins for every investor. Lendmire is a mortgage broker, not a lender. It places files with wholesale lenders, so the program that suits you depends on your property, your credit, your leverage need, and how you document the deal.

NerdWallet notes that rental lines come with a smaller pool of lenders and lower borrowing amounts than primary-home lines, because lenders see higher default risk on investment property. Yahoo Finance adds that lenders weigh both the borrower’s credit and the property’s financials, and that pricing and fees tend to run higher.

That is why a broker helps. A broker shops several wholesale programs and matches your scenario to the one whose rules you actually meet. Availability for these lines is limited to Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint, including Washington, D.C.

How the Two Loans Fit Together

Think of two files that never talk to each other. The first is the equity line. The second is the purchase loan on the new rental.

The line is secured by the property but underwritten on you: your credit, your debt-to-income ratio (DTI, the share of monthly income that goes to debts), and your equity. The purchase loan is a DSCR loan. DSCR stands for debt service coverage ratio, which compares the property’s monthly rent to its monthly payment of principal, interest, taxes, insurance, and any HOA dues (together, PITIA). Rent that covers PITIA once gives you a 1.00. Many select programs start there, and a separate select-lender path goes below 1.00, with leverage and terms adjusted.

Your line payment generally stays outside that ratio. Some non-DSCR purchase lenders do count it in DTI, so the loan type matters. For more on how these loans work, see the complete DSCR loans guide.

Step by Step: From Equity Line to Closing

1. Size the line. Start with the property’s value times the allowed CLTV, then subtract every lien already on it. CLTV (combined loan-to-value) adds all loans on the property together and divides by its value.

2. Qualify personally. The lender checks your credit, your DTI, and the property type. On an investment line, DTI maxes out at 50%, and it is calculated on the interest-only payment at the full line amount.

3. Value the property. An investment line tops out at $500,000, and full appraisals begin above that size. So an investment line is almost always valued with an automated model, and many close without a traditional appraisal. You can still ask for a full appraisal.

4. Draw the funds. At least 75% of the line is drawn at closing. Size the line to the down payment and closing costs you need, not the most equity you could pull.

5. Document the money. The purchase lender wants a paper trail showing where the down payment came from. Borrowed funds are commonly accepted for the down payment or closing costs with documentation. They do not count toward reserves, which are the cash you hold after closing.

6. Close the DSCR purchase. That loan looks at the new rent against the new payment.

Experian lists buying another rental as a common use for these lines, since it can supply the down payment without draining savings or refinancing your current mortgage.

A Worked Example in Percentages

Say your existing rental is worth 100% of its value, and its first mortgage is 45% of that value. At a 70% CLTV ceiling, total debt can reach 70%, so the line has room for about 25% of the property’s value. The $500,000 cap and your DTI can shrink that further.

Now run the purchase. A DSCR purchase typically lands at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage purchase programs reach 85% LTV with about a 700 score or better. If the line funds that down payment, the new property carries near-full financing across two properties and two liens.

Say the new rental’s rent clears roughly 1.2x coverage. The lender may approve that purchase on the property alone. But your real monthly picture also includes the line payment, the new loan, the old mortgage, repairs, vacancy, and management. DSCR counts none of those except PITIA. A strong ratio is not the same as positive cash flow.

Two Ways to Choose the Collateral

You can borrow against your own home or against a rental you already own. Each works differently.

The rental line keeps the lender’s claim on the rental if it underperforms. The primary-home line is easier to size, but a default puts your house on the line. Both Experian and NerdWallet stress that a HELOC is secured by the property, so foreclosure risk is real. Texas primary residences are capped at 80% combined loan-to-value, so the higher tiers never apply there.

The genuine toss-up is leverage versus risk. Primary-home equity usually runs deeper. The rental route keeps your family home out of the picture. Plenty of investors choose the second, even though it caps the line lower.

What Lenders Look For

Across the wholesale network, a few rules shape every file.

• Credit: On an investment line, 700 is a hard floor with no tier beneath it. Scores of 700 and 720 both reach 70% CLTV, so a higher score buys eligibility, not extra leverage.
• Property type: Single-family homes, 2-4 units, PUDs, townhomes, and condos (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural property are not offered.
• Title: The property must sit in an individual’s name or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest difference from DSCR loans, where LLC ownership works subject to program terms. If your rental is already in an LLC, you need a vesting change or a DSCR cash-out refinance instead.
• Structure: Investment lines run a 5-year interest-only draw, then a 25-year repayment. Pricing floats the whole way and never converts to fixed.
• Line size: $25,000 to $500,000 on investment property.
• Exposure: You can hold up to three lines, and borrowers with more than 15 financed properties are not eligible.
• Listed property: In some states (IN, NC, PA, TN, TX, and WA), a property listed for sale in the past 60 days is ineligible.

These are typical guideline ranges, not guarantees. Every figure is subject to lender guidelines and full file review.

Where the Rules Break

Market figures run higher. Experian reports that a typical investment-property line allows up to 80% loan-to-value across the broader market, with at least 20% equity left after a full draw. On this network, an investment line stops at 70% CLTV.

A bigger line is not always better. Because 75% of the line draws at closing, an oversized line becomes debt on day one.

Credit and a bigger down payment cannot erase caps. A larger down payment can lift your coverage ratio, but it never erases leverage caps, credit floors, or reserve rules. The strongest files clear both tests: enough equity and enough rental coverage.

Sub-1.00 files and no-ratio loans. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. A no-ratio structure is available only through select lenders, generally for borrowers who already own a primary residence. Both are narrower paths than a standard file.

Reserves vary. DSCR reserves change with lender, leverage, loan size, and transaction type. They are commonly around 6 months of PITIA, can be waived on conservative rate-term files at modest leverage under $1,500,000, and step up toward 9 months on larger loans. Borrowed down-payment funds do not count toward them.

Is It the Right Move? A Short Checklist

Lean toward this strategy if:

• Your equity after existing liens clears the 70% CLTV test with room to spare.
• Your credit is at 700 or better and your DTI sits comfortably under 50%.
• The old rental’s cash flow or your salary can carry the line payment even if the new unit sits vacant for a while.
• The new property’s rent supports a coverage ratio well above the minimum.

Think twice if you would be stretching the line to its maximum, if a vacancy would force you to cover three payments from salary, or if you do not have reserves left once the money is drawn. The line is only as safe as your ability to pay it while the new property stabilizes.

If you would rather pull equity without a personal-DTI test, a DSCR cash-out refinance is underwritten on the property’s rent instead. Lendmire’s piece DSCR Refinance vs Investment Property HELOC to Buy Another Rental walks through the tradeoffs.

Key Terms Defined

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

DSCR: Debt service coverage ratio, the property’s monthly rent divided by its monthly PITIA.

DTI: Debt-to-income ratio, the share of your monthly income that goes to debt payments.

Draw period: The stretch when you can borrow from the line and pay interest only.

Reserves: Cash you must hold after closing to cover future payments.

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