Best HELOC Program to Buy a Second Property

The Quick Read: A home equity line does not buy your second property; it supplies the down payment cash, while a separate purchase loan, usually a DSCR loan for a rental, pays for the property itself, and the purchase lender decides whether borrowed money counts toward the down payment. DSCR stands for debt service coverage ratio, which compares a rental’s income to its monthly housing payment. The best program for your situation depends on which property secures the line, your credit profile, and how much combined leverage you can carry.

• On an investment property line, the ceiling on this network is 70% CLTV (combined loan-to-value, meaning all loans against the property) with a 700 minimum credit profile.
• On primary-residence and second-home lines, the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile.
• A DSCR purchase loan typically lands at 75% to 80% LTV, so the line only needs to cover the down payment and closing costs.
• Clearing the DSCR test does not mean the rental cash-flows, and the line payment sits outside that test.
• Ask the purchase lender about borrowed down payment funds before you open or draw the line.

How the Two Loans Fit Together

Think of the line as a funding source and the purchase loan as the acquisition. You borrow against equity in a property you already own, move the draw to the title company, and the second property closes with a different loan. Those are two separate approvals with two separate sets of rules.

That split is why “best program” is a matching question. One lender’s line may suit a primary residence with a large equity cushion. Another suits an investor who owns a paid-down rental. The DSCR lender on the new purchase then has its own view of where the cash came from.

Lendmire is a mortgage broker, not a lender. It places both products through select wholesale lenders, which is how it can compare more than one program for a single file. The complete DSCR loans guide covers the purchase side in full.

Key Terms Defined

HELOC: A home equity line of credit, a revolving line secured by a property you own.

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

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

Lien position: Where a loan sits in line for repayment. A first lien is paid before a second lien.

PITIA: Principal, interest, taxes, insurance, and any association dues, the full monthly housing payment.

Seasoning: The time money or a loan must age before a lender treats it as settled.

Reserves: Liquid cash a lender wants left over after closing, often counted in months of PITIA.

Which Property Should Secure the Line?

The collateral choice drives almost everything else. Leverage caps, credit floors, and title rules all change with it. Across Lendmire’s wholesale network, the three options compare like this.

The primary home usually offers the most leverage and the widest property eligibility. The tradeoff is risk: if you miss payments, the home you live in is the collateral. A line against an existing rental keeps that risk off your residence, but the ceiling is lower and the credit bar is higher.

A line above $500,000 is primary-residence only. It needs a 700-or-better credit profile (720 on the 5-year draw structure), caps at 75% CLTV, and requires a full appraisal.

Title is the sharpest difference from a DSCR loan. These lines require the individual borrower or a revocable living trust on title. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold it. If a rental already sits in an LLC, the usual fix is a vesting change or a DSCR cash-out refinance instead.

How Underwriting Treats the Line and the Purchase

Here is the sequence, step by step.

1. The line is underwritten on you and the collateral. Lenders look at credit, a debt-to-income ratio of 50% at most (45% for credit profiles from 600 to 679), and equity. Qualification runs on the interest-only payment calculated on the maximum draw.

2. Value is checked. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. A higher CLTV may call for a second valuation. You can also ask for a full appraisal.

3. You close and draw. At least 75% of the line is drawn at closing on both structures this network uses. Size the line to the need, not to the maximum available.

4. The funds move with a paper trail. The purchase lender will want to see where the down payment came from. Some accept a documented draw as the full down payment. Others limit the borrowed share or want part of it in your own seasoned funds.

5. Reserves are checked separately. Many purchase lenders accept borrowed money for the down payment and closing costs but not for reserves. You may fund the purchase with the line and still need your own cash for the cushion.

The order matters. Talk to the purchase lender before you open or draw the line, because the answer on borrowed funds changes how much you need to bring from your own accounts.

The Purchase Side: What the DSCR Loan Wants

Most DSCR purchases land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV (15% down) with roughly a 700-plus score. Credit floors start at 620 in parts of the network, most programs want about 660, and 700-plus opens the strongest leverage tiers.

On coverage, 1.00 is where many select programs start, and stronger ratios earn better terms and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Reserves vary by lender, leverage, and loan size, and about six months of PITIA is common.

Manufactured homes, log homes, and barndominiums are not offered under the DSCR programs in the network.

Draw Period, Repayment, and the Payment Step-Up

On primary residences and second homes, the network offers two draw structures. One is a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other is a 5-year draw followed by a 25-year repayment. Investment lines use the 5-year draw and 25-year repayment only.

The CFPB describes a line as an open-end credit line you can borrow against repeatedly during a draw period. It gives 10 years as an example. It also notes that these lines usually have variable pricing, and some plans let you convert part of a balance to fixed. On this network, pricing floats through both the draw and the repayment period and never converts to fixed.

The CFPB’s HELOC booklet points out that the payment changes when the draw ends and repayment begins. That step-up is the moment many investors forget to plan for. The new rental needs to carry its own loan and, eventually, the amortizing line payment too.

You pay interest only on what you borrow, not the full limit. That works in your favor on a flexible line. On this network, though, most of the line is drawn at closing, so the practical savings come from sizing the line correctly. Compare total costs across options, not one headline number.

Where the General Rule Breaks

The standard pattern is a line on your home funding a down payment on a DSCR rental. These exceptions change it.

• A fully borrowed down payment. Borrowing the entire down payment means you finance close to the full purchase price across two loans. Some purchase lenders will not allow it, and combined leverage across both properties rises sharply.
• Seasoning on the funds. Some purchase lenders want drawn money to sit in your account for a period before closing. Treat this as lender-specific and ask first.
• Title already in an LLC. The line cannot be placed on it. A DSCR cash-out refinance is the usual alternative. On most of the network it tops out around 75% LTV, with about six months of seasoning as the common expectation.
• Ineligible property types. The lines do not accept manufactured homes, co-ops, condotels, log homes, commercial or mixed-use property, or agricultural zoning. Condominiums, including non-warrantable ones, townhomes, PUDs, single-family homes, and two-to-four-unit properties are eligible.
• A listed property. A property listed for sale, or listed in the past 60 days, is ineligible in some states.
• Credit events. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family history is treated differently on different programs, so the exact history matters.
• Too many properties. A borrower is limited to three lines, and an investor with more than 15 financed properties is not eligible.
• A low valuation. A lower value shrinks the line or breaks the CLTV test, which can leave you short of the down payment you planned on.
• Buy, rehab, refinance. The line can fund a purchase and renovation, with a later refinance repaying it. That plan only works if the later appraisal and rent cooperate.

Availability is narrower than the DSCR side. These lines are offered in Lendmire’s 16 full-service states, while its DSCR investor programs run across 41 markets, including Washington, D.C.

What a Worked Example Looks Like

Consider an investor with a primary home, a credit profile above 720, and a strong equity cushion. She wants a rental at 75% LTV on the purchase, so she needs 25% down plus closing costs. The line is sized to that, not to the maximum available. Her first mortgage plus the new line stays under the CLTV cap on her home. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

The DSCR lender looks at the new property’s rent against its own payment. Say the coverage comes in near 1.2x. That clears a 1.00 benchmark, but the number only compares rent to PITIA. Repairs, vacancy, management, utilities, and capital expenses all sit outside it.

Her real monthly picture carries two payments, the new mortgage and the line. The honest test is whether rent covers the new loan, the line, and the operating costs. If it only clears the first, she has a coverage ratio, not a cash-flow cushion.

Now consider a second investor who owns a paid-off rental inside an LLC. The equity is there, but the line cannot sit on LLC-titled property. He either moves title into his own name or uses a DSCR cash-out refinance, subject to program terms. Same equity, different tool.

Line or Cash-Out Refinance?

A line keeps your existing first mortgage in place and adds a second lien. That matters when your current first mortgage terms are worth keeping. A cash-out refinance replaces the first mortgage and pays you the difference, which resets the loan.

A line usually fits when you need a defined amount for a down payment and want to leave the first loan alone. A cash-out fits when the first mortgage is unattractive anyway, when the property sits in an entity, or when the line limits are too low.

If you already hold a line and wonder about adding another, read Lendmire’s guide to opening a second HELOC alongside the first.

How to Pick the Right Program

Work through these in order.

1. Name the collateral. Primary home, second home, or rental, plus how it is titled.

2. Check your credit tier. 90% CLTV on a primary or second home requires 720-plus. An investment line requires 700.

3. Size the line. Down payment plus closing costs, not the maximum equity.

4. Ask the purchase lender first. Confirm how it treats borrowed funds, seasoning, and reserves.

5. Stress the two payments. Run rent against the new loan, the line, and operating costs, including the payment step-up at the end of the draw.

6. Compare more than one option. Programs differ on credit, valuation, and property eligibility, which is where a broker earns its keep.
