Using a HELOC for a Fix-and-Flip Down Payment

You may be able to use an investment property HELOC for a fix-and-flip down payment if both lenders approve the borrowed funds. The line is secured by a rental you already own. The flip loan finances a separate purchase. That setup can supply cash, but it also puts debt on two properties.

Start with the source of repayment. A flip may sell late, need more work or bring less than planned. Your HELOC payment remains due while you wait. The best use of the line is a defined cash gap with a clear plan to restore the balance.

The investment property HELOC program is for a non-owner-occupied source property. It includes a debt-to-income review. Rate and payment terms are quoted per file. Do not assume a loan against your own residence follows these same rules.

Use the calculator to explore the funding plan. Then replace estimates with the two lenders’ written terms and the closing agent’s figures.

How the estimate adds up

Total equity, unfunded rehab, and fees	$42,200
Earnest money credited once	$5,000
Own cash used, including deposit and later payments	$40,043
One extra month: interest and property carrying cost	$4,034

• These are planning estimates before tax, not a loan offer. Property value, title, documented income, existing debts, and lender approval can reduce the available amount.
• The HELOC draw occurs at closing. Hard-money rehab funding is spread evenly at the start of each hold month. Unfunded rehab is included in cash needs; use the separate draw-timing guide to model reimbursement delays.
• Profit deducts interest and fees. Principal repayment is handled through the sale and cash contributions, so it is not deducted twice.

Name the two properties and two debts

Call the existing rental Property A and the new flip Property B. Put those labels on your loan worksheet. This simple step keeps each debt tied to the right asset.

A HELOC is a line that lets you draw against equity during its borrowing period, subject to its terms. The CFPB’s HELOC explanation describes this basic structure. For an investment property line, rely on the actual business loan agreement for fees, access to funds and repayment.

Debt	Property securing it	Planned use
Existing first mortgage.	Rental A.	Debt already owed on that rental.
Investment property HELOC.	Rental A.	Approved cash for the next project.
Fix-and-flip loan.	Flip B.	Purchase advance and approved rehab funds.

This example uses a HELOC behind an existing first mortgage. The available lien position depends on the file. Review the investment property HELOC requirements before treating estimated equity as usable credit.

Equity is an estimate of value less debt. It is not the same as an approved line or money ready to wire. The lender still needs to review value, current liens, title, income and other file details. A line approval may also have conditions that remain open before funding.

Get agreement on borrowed funds before committing cash

Ask the HELOC lender whether the proposed flip use is allowed. Ask the flip lender whether its required contribution may come from that line. Show the amount, property securing the debt, payment terms and expected draw date.

Some loan programs allow secured borrowed funds under specific rules. For example, Fannie Mae’s secured funds guidance addresses debt payments, loan terms and proof of the transfer. Those rules do not establish eligibility for a private flip loan. Get a decision for your actual purchase.

Use direct questions when you send the deal. Will you accept this HELOC for the purchase contribution and closing costs? Does any required cash have to come from my own unborrowed funds?

What loan documents and bank records do you need? How will the new debt affect qualification and required reserves? Can the line also fund early rehab bills under both agreements? Which approvals must be complete before the purchase closing?

Do this before waiving a financing condition or placing more money at risk. A lender’s review of the flip value does not prove acceptance of your cash source.

The fix-and-flip down payment funding overview covers another way to address a cash gap. Compare the collateral, payment and total debt of each route. A lower closing wire alone does not tell you which choice costs less.

Keep the HELOC income review in the plan

This investment property HELOC uses debt-to-income qualification, or DTI. DTI compares monthly debt payments with gross monthly income. The CFPB’s DTI definition explains that calculation and notes that limits vary by loan and lender.

Have the HELOC team review your income, existing mortgages and other debt. Ask how it will treat the planned flip loan and the HELOC payment. Do not assume rental income will be accepted dollar for dollar or that vacant property has qualifying rent.

The two reviews can move at different speeds. A strong flip may still wait on source-property title or income documents. A funded line may still be unusable for a specific purchase if the flip lender rejects the source.

Build the schedule around completed conditions. Leave time to transfer funds and show the bank trail. Avoid making the first line draw on the morning the seller expects a closing wire.

Work the purchase cash gap from actual costs

The following numbers are hypothetical, not a customer result or a Jaken Finance Group quote. Assume both lenders have accepted the plan. The flip lender funds a $225,000 purchase advance and holds $70,000 for approved rehab work.

Purchase item	Amount
Price of Flip B.	$250,000
Initial purchase advance.	$225,000
Purchase price gap.	$25,000
Closing and financing costs paid with cash.	$8,000
Total borrower funds for closing.	$33,000
Earnest money already paid from investor cash.	$5,000
Remaining closing wire from the HELOC.	$28,000

The deposit reduces the closing wire. It does not make the purchase cost $5,000 more. The investor has supplied $33,000 at closing: $5,000 of cash and $28,000 of borrowed funds.

If the deposit had also come from the HELOC, its balance would include that draw. The wire might still be $28,000, but total line use for closing would be $33,000. Record both the source and the credit.

Actual costs may include lender charges, title work, taxes, insurance, recording and prepaid interest. Ask which costs reduce loan proceeds and which require a separate payment. Use the final settlement statement to replace each estimate.

Budget the gap before the first rehab draw

A rehab holdback is money set aside under the flip loan for approved work. It is not always available as cash on the day you close. Review the fix-and-flip draw process before promising a contractor immediate payment from loan funds.

In this example, assume $15,000 of early eligible work must be paid before the first reimbursement. The investor draws that amount from the HELOC. The balance rises from $28,000 to $43,000.

Two months later, assume the flip lender releases a $15,000 draw after its required review. The investor uses it to repay the same $15,000 on the line. The HELOC returns to $28,000. The flip loan balance rises as its rehab funds are drawn.

There is no new profit from this transfer. One debt has funded the work until the other loan reimburses it. If you spend the draw on a different project, the first HELOC balance remains higher.

Agree on the details before work starts. Which work must be complete before a draw request? What proof of payment, photos or lien documents are required? Who pays inspection and draw fees?

Is any part of the approved amount held until final completion? How much cash can you provide if a draw takes longer?

Use a clear scope of work to link each bill to the approved budget. A paid invoice for extra work does not prove that the lender will fund it.

Build a weekly cash schedule during the busiest rehab phase. List each bill’s due date, the cash available that week and the expected draw date. Test what happens if one draw arrives a week late. The largest gap may occur before the final project balance peaks.

Leave room for work that was missed in the first scope. A change order can require cash before the lender has reviewed the revised budget. Get the price and funding answer before telling the contractor to proceed. This also helps keep the line available for its approved purpose instead of spending every dollar at closing.

Separate interest cost from the required payment

For cost planning only, assume a 10% annual rate on the line. This is an invented rate for the example. It does not describe the program’s rate or promise interest-only payments.

Assume the balance stays at $43,000 for two months, then $28,000 for four months. A simple monthly interest estimate is:

Period	Calculation	Estimated interest
First two months.	$43,000 × 10% × 2 ÷ 12.	$716.67
Next four months.	$28,000 × 10% × 4 ÷ 12.	$933.33
Six-month total.	Sum of both periods.	$1,650.00

Real interest may use daily balances and the agreement’s day-count method. The required payment may also include principal. If so, model the cash payment and the changing balance. Principal repayment uses cash but is not an added interest expense.

Ask about opening costs, annual charges, minimum draws, early closure costs and any change from the draw period to repayment. Check whether the quote is fixed or variable. If variable, test the stated rate adjustment terms. Do not infer those terms from the word HELOC.

Show the sale payoff and profit separately

Assume all $70,000 of rehab funds are eventually drawn. The flip loan’s principal reaches $295,000. The following example also assumes $16,000 for senior loan interest and property carrying costs. Those costs are paid along the way from investor cash.

Whole-project cost	Amount
Purchase.	$250,000
Rehab.	$70,000
Initial closing and financing costs.	$8,000
Senior interest and property carrying costs.	$16,000
HELOC interest estimate.	$1,650
Selling costs at an assumed 7% of $400,000.	$28,000
Total cost.	$373,650
Sale price less total cost.	$26,350

That is estimated profit before income taxes and any costs omitted from the assumptions. It is not the amount wired to the investor at sale.

At a $400,000 sale, subtract $28,000 of selling costs and $295,000 of flip principal. That leaves $77,000. Repaying the remaining $28,000 HELOC principal leaves $49,000.

The investor previously paid $22,650 from cash: the $5,000 deposit, $16,000 carrying costs and $1,650 line interest. Recovering that cash leaves the same $26,350 profit. This second check prevents loan principal from being counted twice as a project expense.

Get dated payoff statements for the actual sale. Since the line is secured by Rental A, do not assume Flip B’s closing will clear it automatically. Arrange the payment and verify the posted balance.

Stress the sale date and price together

Now assume the sale slips by three months and closes at $385,000. Added senior and property carry is an assumed $2,500 per month. Interest on the unchanged $28,000 line adds about $233.33 per month at the example rate.

The delay adds $8,200 in total. The lower price cuts revenue by $15,000, while the assumed 7% selling cost falls by $1,050. Estimated profit drops from $26,350 to $4,200.

This stress case includes no new rehab cost or loan extension fee. Add them if the situation calls for them. Also check the line’s required payment dates during the delay. A near-break-even flip can still require substantial monthly cash.

An undrawn line balance is not automatically accepted as a reserve. Ask each lender what funds qualify. Keep enough accessible cash for the approved reserve requirement and your own delay plan.

Prepare one clear funding file

Keep the source rental and flip records distinct, but show how the money moves between them. Include the HELOC agreement, latest mortgage statements, income records and the line’s current available balance.

For Flip B, include the purchase contract, deposit receipt, rehab scope, lender terms and estimated closing statement. Add bank records showing each HELOC draw and transfer. Explain any entity or account names that differ between the two files.

Maintain a small ledger with date, amount, use, property and proof. Track line principal apart from interest, fees and rehab bills. Save the final sale statement and the payment that restores the line.

Before choosing the amount, compare other investment property HELOC uses. If you plan to keep the next property as a rental, review using a HELOC for a DSCR down payment. Long-term rent needs a different repayment plan from a flip sale.

Bring both property addresses, the cash gap and your payoff plan to an investment property HELOC review. Ask for written terms that fit the full deal before treating the line as closing cash.
