HELOC Checklist to Buy an Investment Property With Home Equity

The Quick Read: Buying a rental with home equity is a two-loan move. You open and draw a home equity line of credit (HELOC), then use the cash toward a separate purchase loan. The purchase lender decides whether that borrowed money counts as your down payment, so confirm that before you draw.

• A line on an investment property tops out at 70% combined loan-to-value (CLTV) on this network, with a 700 minimum credit score and a $500,000 maximum line.
• A line on your primary residence can reach 90% CLTV, but only at a 720-or-better credit profile.
• The line’s payment is variable and interest-only during the draw, and it comes out of your pocket on top of the new loan.
• The rental still has to cover its own payment. Select DSCR programs start at 1.00 coverage, and stronger ratios open better terms.
• Every figure here is subject to lender guidelines and full file review. None of it is a commitment to lend.

How the Two Loans Fit Together

A HELOC is the source of your cash. The purchase loan is the acquisition. They are separate files with separate underwriting, and they do not have to come from the same lender.

The order matters. The line closes first. You draw. Then the purchase lender reviews the file and decides whether that draw can serve as your down payment. Some purchase programs accept a fully borrowed down payment. Others want to see a share of your own funds. Program by program, the answer changes, so ask before you open the line.

A DSCR loan is a business-purpose investment loan. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR stands for debt service coverage ratio: monthly rent divided by the full monthly payment on the property (principal, interest, taxes, insurance and any association dues). The complete DSCR loans guide walks through that math in full.

Many investors pair the two products. SuperMoney describes the usual split as a HELOC for the down payment and an investment mortgage for the rest, which balances rate risk against liquidity.

Step 1: Pick the Collateral

You have two routes, and they run on different rules.

Route A is a line on your primary home. This is a consumer-style product. It looks at your credit, your personal debt-to-income ratio (DTI) and the equity in the home.

Route B is a line on a rental you already own. The rental secures it, and the ceiling is lower because lenders treat investment collateral as riskier.

Two cautions apply to Route A. First, the 90% ceiling never applies without that 720 pairing. Second, a line above $500,000 is for primary residences only, needs a 700 or better credit profile (720 on the longer draw structure), caps at 75% CLTV, and requires a full appraisal.

Property type matters too. Single-family, 2-4 unit, townhome, PUD and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not.

Step 2: Size the Line With Equity Math

Usable equity is the home’s value times the maximum CLTV, minus what you owe on the first mortgage. Yahoo Finance gives the starting definition: equity is a home’s value minus the outstanding mortgage.

Here is the math in percentages. Say your first mortgage equals 55% of the home’s value. On a primary residence at 90% CLTV with a 720+ profile, the ceiling leaves room for a line worth up to 35% of value. On a rental at 70% CLTV with the same first mortgage, the room shrinks to 15% of value. The line caps and your DTI can shrink it further.

Now compare that number to what the purchase needs. Select programs reach 85% LTV (15% down) with roughly a 700+ score, and a lower-leverage purchase loan means a larger down payment. Add closing costs and reserves, which are commonly around 6 months of PITIA (principal, interest, taxes, insurance and association dues). Reserves are sometimes evaluated separately from the down payment itself.

Size the line to the need rather than to the maximum. At least 75% of it is drawn at closing on this network, and you pay interest on what you draw, so a line far larger than the purchase requires means paying interest on money you do not need. A later draw typically carries a minimum, often $1,000.

A larger down payment can lift your coverage ratio by shrinking the purchase loan. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Step 3: Check Your First Mortgage and Title

A HELOC here is a standalone line in first or second lien position. If you already have a first mortgage, the new line sits behind it. Read your note and security instrument for language on additional liens and transfers.

If your first mortgage is itself a DSCR loan, its documents must allow a junior lien. Some second-lien programs also exclude non-QM first loans. Find this out early, because a prohibition ends the plan before it starts.

Title is the sharpest structural difference from a DSCR loan. A HELOC property must be held by you as an individual or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a DSCR cash-out refinance instead. DSCR loans themselves can close in an LLC, subject to program terms.

Other eligibility limits apply across the network:

• You can hold no more than three lines.
• You cannot own more than 15 financed properties.
• A line on a home you plan to sell is a bad fit. Several states bar lines on properties that are listed or recently listed.
• Recently bought or refinanced rentals face seasoning limits.

Step 4: Understand How the Line Behaves

HELOC payments move. The CFPB says these lines usually carry a variable interest rate, so payments may change from month to month. It also notes the draw period could last 10 years, for example, and that some lenders let you convert part of the balance to a fixed rate.

The lines on this network work a little differently. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Primary residences and second homes also have a 3-year draw with a 17-year repayment option. Pricing floats through both the draw and the repayment period and never converts to fixed. Any quote you see carries its own draw and repayment structure.

The same CFPB booklet lists the disclosures a lender must provide and advises getting three estimates. Take that advice. Compare draw length, repayment length, minimum draws and what happens to your payment when the draw ends.

Credit and income rules come next. The program floor is 600, and it uses a single-bureau score tied to the primary wage earner. Reports must be no more than 90 days old at closing. DTI maxes at 50%, drops to 45% for scores from 600 to 679, and anything above 45% needs a 680 minimum. The qualifying payment is interest-only on the maximum draw. A bankruptcy needs 4 years of seasoning from discharge or dismissal.

Step 5: Build the Paper Trail

Document every dollar. Keep the HELOC agreement, the draw confirmation, the transfer to escrow or title, and the statement showing where the money went. A purchase underwriter will ask where the down payment came from, and a clean trail answers that.

Valuation is usually simple. A line at or below $500,000 ordinarily runs an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation. Because an investment line caps at $500,000, it commonly closes without a traditional appraisal. You may still request a full appraisal.

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

Availability is narrower than the DSCR footprint. HELOC placements run in Lendmire’s 16 full-service states, while DSCR programs span 41 markets, including Washington, D.C.

Step 6: Test the Rental on Its Own

This is where equity-funded deals fail. The new rental has to cover its own payment, and your line payment sits outside that test.

DSCR compares rent to the property’s own payment. The HELOC payment does not enter that ratio. It still comes out of your pocket, and it counts against you on any loan judged by personal DTI. Conventional and bank-statement lenders add the new line’s payment to your DTI. A DSCR purchase reviews the property’s coverage.

Coverage floors vary. 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.

Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. Run your own cash flow after the line payment too.

Stress-test the plan against four events:

If rent barely covers the purchase payment and you add a variable second lien, you may stretch the file too far. The purchase loan structure matters. The spine is the 30-year fixed. Extended 40-year terms and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them.

Step 7: Plan the Exit Before You Draw

The line is short-term money. Write down how you will repay it before you open it.

Typical exits are refinancing after the property stabilizes or selling and repaying the line. SuperMoney lists both. A refinance only helps if the property supports it. A DSCR cash-out refinance tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. Weigh that against the cost of keeping the line open before you commit to either path. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Remember what a fully financed deal means. If borrowed money covers the down payment, you have little equity of your own in the property. Appreciation is the only cushion until you repay the line.

When to Skip This Strategy

Some situations argue against using a HELOC for a buy-and-hold purchase:

• Your coverage ratio is thin and the line payment would make cash flow negative.
• You cannot repay the line if the exit slips.
• Your credit sits below the 700 investment floor or the 720 needed for top primary-home leverage.
• Your property sits in an LLC and you do not want to change vesting.
• You have no cash outside the line for reserves and repairs.
• You are unwilling to risk your home. A line on your residence puts the house on the table if the debt goes unpaid.

Short-term plans such as repaying within a refinance cycle fit a line better than a long hold.

Key Terms Defined

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

Draw period: The stretch when you can borrow from the line, usually paying interest only.

DTI (debt-to-income): Your monthly debts divided by your monthly income.

Reserves: Liquid cash a lender wants you to keep after closing, measured in months of PITIA.

Seasoning: The waiting period a lender wants after a purchase or refinance before certain loans are available.
