Investment Property HELOC Requirements to Buy Before You Sell Your Home

The Quick Read: A home equity line of credit (HELOC) can supply down-payment cash for a rental before your current home sells, but the line must be open first, the purchase lender must accept borrowed funds, and the rental still has to pass its own coverage test.

• On an investment property, the network’s ceiling is 70% combined loan-to-value (CLTV), with a 700 credit minimum and a line of up to $500,000.
• Lines on a primary residence reach 90% CLTV only at a 720-or-better credit profile.
• Most DSCR purchase programs treat HELOC cash as a down-payment source, but reserves usually have to come from unborrowed money.
• The HELOC payment generally stays outside the DSCR ratio, but it still comes out of your real cash flow.
• A HELOC never makes a purchase zero-down. It only changes where the down-payment cash comes from.

What does a HELOC actually do in a buy-before-you-sell plan?

A HELOC is a loan separate from your purchase loan, and it exists to put cash in your account. The purchase loan is a second, independent approval.

Picture an owner who wants a rental but whose money is locked in a home that has not sold. Selling first means a gap with no rental and a cash pile with nowhere to go. Buying first means finding down-payment cash while the old home still has a mortgage on it. The line fills that gap.

Equity is the home’s value minus what you owe. A line borrows against that equity, which is why the first question is always which property secures the line. Many articles blur this, and you should not. The answer changes the rules, the limits and the risks.

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 purchase loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide covers that loan in full.

Which property secures the line: the rental or the home you’re selling?

There are two versions of this plan, and they run on different tables. One line sits on a rental you already own and keep. The other sits on the home you plan to sell and is repaid when that sale closes.

Two details in that table matter most. On an investment property, 720 and 700 both reach the same 70% CLTV. Higher credit buys eligibility, not extra leverage, and nothing sits below the 700 floor. And the 90% figure on a primary residence exists only at a 720-or-better profile, so treat it as a top-tier ceiling.

If you have no rental, the home you are selling is the only collateral available. If you already own a rental with equity, a line on that rental funds the down payment without touching the home you are about to list.

What are the investment property HELOC requirements across the network?

Lendmire arranges these lines through select wholesale partners and is never the lender. Every figure below is a typical guideline range, subject to lender guidelines and full file review, and none of it is a commitment to lend.

Leverage and size. An investment line caps at 70% CLTV. CLTV counts your first mortgage plus the new line against the property’s value. A first mortgage at 45% of value leaves room for a line of up to about 25% of value, within the $500,000 maximum. Market surveys report that some lenders allow up to 80% on investment lines, per Experian, but the network’s investment ceiling is 70% CLTV.

Credit. An investment line requires at least a 700 score. The score comes from a single credit bureau and is keyed to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores.

Debt-to-income. The maximum is 50%. Lenders review your file on the interest-only payment calculated against the maximum draw, not on what you actually borrow. A large line therefore weighs on your debt ratio even if you plan to draw little.

Valuation. An investment line tops out at $500,000, and full appraisals begin above that size. So an investment line is structurally an automated-valuation file and commonly closes with no traditional appraisal. You can ask for a full appraisal in any case.

Structure. The line sits in first or second lien position. Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment, and no other structure. At least 75% of the line is drawn at closing. The cost floats through both periods and never converts to fixed.

That 75% rule changes the plan. You cannot open a big line as a standby reserve. Most of it is borrowed on day one and accrues cost from then on.

Property and title. 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. The individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot.

Derogatory history and exposure. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files season a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure or short sale at 4. A borrower is limited to three lines, and anyone with more than 15 financed properties is not eligible.

Where these lines are available. The lines are offered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. That is narrower than the DSCR footprint of 41 markets, including Washington, D.C.

How does the purchase lender treat the borrowed cash?

This is the real gate. Across the wholesale network, DSCR purchase programs split three ways on documented borrowed funds. Some accept them as a down-payment source. Some cap the borrowed share. Some want a portion of the down payment from unborrowed money.

Secured borrowing, such as a HELOC draw, is generally treated differently from unsecured borrowing. Credit card advances and similar unsecured sources are generally not accepted. Whatever the source, the cash has to be documented.

Think of three buckets, because lenders do. Reserves commonly run around 6 months of PITIA. They vary by lender, leverage, loan size and transaction type. Some conservative rate-and-term files at modest leverage under $1,500,000 see reserves waived, and larger loans typically step up to about 9 months.

An undrawn line does not count as reserves either. A DSCR lender sees it as permission to borrow, not as money you hold. Your own savings carry the reserves.

On the purchase itself, most files land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV with a 700+ score. A bigger down payment shrinks the loan and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear two tests: enough equity and enough rental coverage.

What is the step-by-step order of operations?

1. Open the line before you list. Lenders look at your equity, credit and debts. A line is hard to open once a home is listed or under contract. In NC, PA, TN, TX and WA, a property listed for sale, or listed within the past 60 days, is ineligible for these lines.

2. Draw the cash and document it. The funds need a paper trail from the line to your account. Some lenders want borrowed funds seasoned in the account before the purchase. Others do not. Seasoning rules vary by purchase lender, so ask before you draw.

3. Run the purchase lender’s borrowed-funds test. Confirm which of the three treatments your program uses before you commit to a contract.

4. Split the cash into down payment, closing costs and reserves. Confirm that the reserve bucket comes from unborrowed money.

5. Close the purchase. The DSCR loan tests the new property’s rent against the new loan’s payment.

6. Choose the exit for the line. You can sell the old home and pay the line off at that closing. Or you can keep the line and carry the balance.

If the line sits on the home you sell, the sale pays it off alongside the first mortgage. Selling the secured property also ends the line.

How do the draw and repayment periods work?

The Consumer Financial Protection Bureau describes a HELOC as an open-end line you can borrow against repeatedly during a draw period, for example 10 years. It also notes that a lender may stop further draws if the home’s value drops significantly. If you fall behind, you could lose the home that secures the line.

The same agency says a HELOC on a home with an existing mortgage is a second mortgage, paid in addition to the first. The Federal Trade Commission adds that HELOCs typically carry variable rates and that you pay only on what you borrow. On the network’s investment lines, the interest-only draw lasts 5 years, then the line fully amortizes over 25 years. The monthly obligation steps up when the draw ends.

Where the general rule breaks

The payment stays out of the ratio, but not out of your life. DSCR compares rent to the new loan’s PITIA only. On most files the HELOC payment is not in that ratio. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, management, utilities and capital expenses sit outside the calculation. A down payment funded 100% by borrowing means two loans carried against one rent stream.

Coverage below 1.00. 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. Stronger ratios open better pricing and leverage.

Conventional loans work differently. A purchase loan that is reviewed around debt-to-income would count the HELOC’s minimum payment against you. DSCR avoids that particular math, which is a main reason investors move to it for a pure rental purchase.

Title. An LLC cannot hold title on the line. A DSCR purchase can often close in an LLC, subject to lender program eligibility. If a property is already deeded to an LLC, it needs a vesting change or a DSCR cash-out instead of this line.

Lender discretion. Lender pools for investment-property lines are smaller than for primary homes, and borrowing limits are lower, per NerdWallet. That source also notes that some lenders restrict these lines by location and by whether the home is rented all year.

Draw cliff. A line used for a purchase can reach repayment before the new property stabilizes. Plan the exit before you draw, not after.

Existing first mortgage. A HELOC can limit your ability to refinance the first mortgage later, because the line’s lender may need to approve the change.

Ineligible properties. Manufactured homes, log homes and barndominiums are not offered through the network’s DSCR programs, and the HELOC side excludes the same types.

What does the decision look like in practice?

Run the numbers as percentages. Say you own a rental worth 100 units of value with a first mortgage at 45%. At 70% CLTV you could draw up to about 25% of value, subject to the $500,000 cap. You then buy a new rental with 25% down plus closing costs, which puts the purchase at 75% LTV. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

The line has to cover that down payment and closing costs while your own savings cover reserves. The DSCR file asks only whether the new rent covers the new payment. A ratio around 1.2x would be a comfortable read. Your own budget asks the harder question of whether rent also covers the HELOC payment, the vacancy and the repairs.

If the plan is to sell the old home, ask what happens when the sale stalls. The line’s cost keeps floating. The new rental’s payment starts. A pause in the sale is survivable only with unborrowed cash behind it.

The alternatives deserve a look too. A cash-out refinance on a rental you keep is a one-time lump of cash, while a line is a revolving one. The right choice depends on your equity, your credit profile and your timeline.

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, which on network investment lines is 5 years of interest-only payments.

Reserves: Liquid funds you hold after closing, usually counted in months of PITIA.

DSCR: Debt service coverage ratio, which compares a property’s monthly rent to its monthly payment of principal, interest, taxes, insurance and HOA dues.

Seasoning: The time money sits in your account, or a loan sits on a property, before a lender counts it.

Automated valuation: A computer-based estimate of home value that stands in for a traditional appraisal.
