## The short answer

Yes. In my files, a documented HELOC draw on your home is an accepted source for your next down payment and closing costs, and its payment counts in your debt-to-income. Open the line while you live there, before you shop, draw only what the purchase needs, and tell the lender the real purpose. On a $400,000 home, 5% down plus about 2.5% in costs is about $30,000: about $188 a month interest-only at an example rate of 7.5%.

You have equity in the house you live in, and you want the next one without selling this one first or emptying your savings. You can use a HELOC for a down payment, and it is one of the most useful moves I teach. Here is how to size the draw, document it for the new loan, time it, and what it does to your qualifying.

## Can you use a HELOC for a down payment?

Yes, you can borrow from your home equity to buy another house. The rule underneath it: borrowed money can go into a purchase only when something you own secures it. You can't use unsecured debt to get secured debt, so a personal loan or a credit card cash advance will not work for a down payment. A draw on a line against your own home is secured borrowing. On a Fannie Mae loan, money borrowed against an asset you own, real estate included, is an accepted source for the down payment, closing costs and reserves, and its payment counts as a debt. Other loan programs have their own version of that rule, and I check it on your file.

Three things come with it:

1. The draw gets documented like any other money, with a paper trail from the line to your account to the closing table.
2. The line's monthly payment counts as a debt on your new loan.
3. Everything on both applications is true: the line's purpose, whether you live in the home, and what you plan to do with it.

The next home has to be what you say it is, too. A primary residence is a home you genuinely move into and live in. A property you plan to rent out is an investment property, and it gets financed as one.

## How much should you draw? Down payment plus closing costs

Draw what the purchase needs, not what the line allows. The math is the same [cash to close](https://nobullshitloans.com/buy/cash-to-close/) every buyer runs: down payment, plus closing costs and prepaids, minus any seller credit. My working assumption on a next primary residence is about 5% down plus about 2.5% for closing costs and prepaids.

**Worked example: Sizing the draw on a $400,000 next home**
- Down payment (5%): $20,000
- plus Closing costs and prepaids (about 2.5%): $10,000
- minus Seller credit: $6,000
- equals: Draw from the line: $24,000
Note: Interest-only on $24,000 at an example rate of 7.5% is $150 a month. Without the seller credit the draw is $30,000 and the payment is about $188.
_Hypothetical. Your real closing costs come from your Loan Estimate. A seller credit can pay closing costs and prepaids, never the down payment, and every loan program caps it._


That seller credit row is why, in late 2026, I lead with concessions over price cuts. Every dollar the seller puts toward your closing costs is a dollar you do not draw and do not pay interest on. How to ask for it is in [making an offer](https://nobullshitloans.com/buy/making-an-offer/).

Your loan program sets the minimum down payment. If you are a veteran keeping a VA loan on the old house, what you need down on the next VA loan depends on your remaining entitlement, covered in [VA entitlement](https://nobullshitloans.com/veterans/va-entitlement/).

Then leave the rest of the line alone. The unused part is an extension of your reserves, for the month the old house sits empty or the water heater goes. On a $150,000 line, a $24,000 draw leaves $126,000 of standby room. One caution: an open line is not cash, so it does not count toward any reserve requirement on the new loan. Plan those reserves from savings.


**Chart: A $150,000 line with only the purchase drawn.** Draw the $24,000 the purchase needs and leave $126,000 open for an empty month or a water heater. Open room isn't cash, so it doesn't count as reserves.

| | Part | Amount |
|---|---|---|
| Your line of credit | Drawn for the down payment and closing costs | $24,000 |
| Your line of credit | Left open as standby room | $126,000 |
| Your line of credit | Total | $150,000 |

_A $150,000 line opened while you still live in the home, with the real purpose and your plans for the house stated on the application. $24,000 drawn at an example rate of 7.5%, interest only during the draw period, is $150 a month. The draw covers 5% down plus about 2.5% for closing costs and prepaids on a $400,000 next primary residence, less a $6,000 seller credit. Hypothetical, not a quote._


## Sourcing the draw for the new loan

Underwriters source large deposits. On a Fannie Mae or FHA loan, that means any single deposit over half your monthly qualifying income, and a down payment draw will clear that bar. A HELOC draw is one of the easiest deposits to source, because the paper trail writes itself, as long as you keep it clean:

- Keep the line's closing documents, which show the line amount, the rate terms and the required payment.
- Draw what you need in one move, into the account you will close from.
- Keep the line statement that shows the draw and the bank statement that shows the deposit.
- Leave the money where it landed until closing. Bouncing it through several accounts only adds paper.

Tell me the date and the amount when you draw. One deposit with its source attached is a non-event in underwriting. An unexplained deposit is not.

## How the HELOC payment counts in your debt-to-income

The new lender counts the line's required monthly payment on what you have drawn as a debt, right next to the new mortgage. During an interest-only draw period that payment is small, which is a big reason this works for working households.

**Worked example: Debt-to-income on the next home, $9,000 a month gross income**
- New home payment (principal, interest, taxes, insurance, PMI): $2,991
- plus HELOC interest-only on $24,000 drawn: $150
- plus Car payment: $400
- equals: Monthly debts: $3,541
Note: $3,541 ÷ $9,000 is about 39%. The line adds less than 2 points.
_Hypothetical: $380,000 loan at an example rate of 6.5% on a 30-year fixed, Chesterfield's 2026 tax rate, $1,500 a year of insurance and PMI at 5% down with a 740 credit score. Assumes the old home's rent fully offsets its payment under the program's rules._


The line is rarely what breaks the ratio. The old house is. If its $2,000 payment counts in full, the same file runs about 62%, far over the line for any loan I would put in front of an underwriter. Whether rent from the home you are leaving can offset its payment depends on the loan program: on a Fannie Mae loan, since September 2, 2026, the lender uses 75% of market rent (not a lease), and that can only offset the old home's payment. The rules for every program are in [keeping your house as a rental and buying the next one](https://nobullshitloans.com/wealth/rent-out-your-house/).


**Chart: What the lender counts each month on $9,000 of income.** The line's $150 is a sliver. Count the old house's $2,000 payment in full and the same file goes from about 39% of income to about 62%.

| | Part | Amount |
|---|---|---|
| Monthly debts when the old home's rent offsets its payment | New home payment | $2,991 |
| Monthly debts when the old home's rent offsets its payment | HELOC, interest only | $150 |
| Monthly debts when the old home's rent offsets its payment | Car payment | $400 |
| Monthly debts when the old home's rent offsets its payment | Total | $3,541 |
| Monthly debts when the old home's payment counts in full | New home payment | $2,991 |
| Monthly debts when the old home's payment counts in full | HELOC, interest only | $150 |
| Monthly debts when the old home's payment counts in full | Car payment | $400 |
| Monthly debts when the old home's payment counts in full | Old home's payment | $2,000 |
| Monthly debts when the old home's payment counts in full | Total | $5,541 |

_$9,000 a month of gross income.

The first row assumes the old home's rent fully offsets its payment under the program's rules; on a Fannie Mae loan the lender uses 75% of market rent, and it can only offset that payment.

Before you shop, I run both versions, with the rent and without it, and check that you can carry two mortgages at once.

## When to open the line: before you shop, while you live there

This is the part people get backwards. This is not "go find the house and then open the HELOC." You open the line, then you shop.

**My take**
My house rule: no more showings until the line has closed and funded. A line you open after you go under contract is racing your closing date, and it changes your file in the middle of underwriting.


Why the order matters:

- **The strongest terms are on the home you live in.** Lines on a primary residence get the highest limits and lower margins, and once you have moved out, that version of the line is gone for that house. The details are in [how a HELOC works](https://nobullshitloans.com/refinance/heloc/).
- **Lines take weeks.** The ones I see most often take about 30 days to close, and a purchase contract runs on deadlines that will not wait for a second loan.
- **New credit in the middle of a purchase causes problems.** Open a line while you are under contract and your credit and debts change mid-file, which sends the underwriter back through it. That is one of the big items in [what not to do before closing](https://nobullshitloans.com/buy/what-not-to-do-before-closing/).
- **The truth has to line up.** The line's application asks whether you live in the home and what the money is for. Once you are under contract on a new primary residence, the honest answer about this house has changed, and the line you would qualify for changes with it.

1. Open the line on the home you live in. Tell the lender the real purpose, the down payment and closing costs on your next home, and your plans for this house.
2. Wait until it has closed and funded.
3. Get pre-approved for the next home with the line's payment counted. I issue a pre-approval only after your income, assets and credit have been documented and reviewed, not estimated: we only pre-approve, we don't pre-qualify. More on that in [pre-approval vs pre-qualification](https://nobullshitloans.com/buy/pre-approval/).
4. Shop and go under contract, using a seller credit to shrink the draw.
5. Draw the down payment and closing costs, and keep the paper trail.
6. Close, move in and make it your home.
7. Rent the old house or sell it, as you planned. Before a tenant moves in, read what your line agreement says about occupancy and renting, and ask the lender if it is not clear.


**Watch out**
Never describe a home on a loan application as one you will keep living in when you are already under contract on the next one. That is a false statement on a loan application. Answer every question truthfully and let the lender decide what it offers.


## HELOC for a second home, investment property or rental

You can put a draw toward other purchases, but the type of property changes the math, and the classification has to be truthful. A second home you will use yourself is its own category with its own rules, so tell me how you will use it and we finance it as what it is. A property you will rent out is an investment property.

An investment purchase needs a much bigger down payment. In my files, plan on 20% down plus closing costs, call it 25% all in. On a $200,000 rental that is about $50,000 of your line, while 5% down plus closing costs on a $400,000 primary residence takes about $30,000 and leaves the old house ready to rent. So if you were moving anyway, buying the next home as a primary residence you move into, and renting the one you leave, takes far less of the line than buying a rental outright.

## The risks, and how to keep them small

- **Your house secures the line.** Fall behind and it is your home at risk, not just your credit score.
- **The rate floats.** Each 1-point rise in prime adds $20 a month on $24,000 drawn.
- **Two houses, two sets of repairs.** Vacancies and repairs on the old house show up at the worst times. That is what the undrawn part of the line is for.
- **The open room can be frozen.** If your home's value drops sharply or your finances change for the worse, federal rules let the lender stop new draws or lower the limit. Don't let the undrawn line be your only cushion.
- **The draw period ends.** Never pay the draw down and the payment converts to principal and interest: $24,000 repaid over 15 years at the same example rate is about $222 a month instead of $150.
- **Selling the old house pays off both loans on it.** If you sell later, the first mortgage and the line both get paid from the sale.

The fix for most of these is paying the line down on purpose. Rent pays the old mortgage first, and every dollar left over goes at the line until it is back to zero. If $800 a month is left over, a $24,000 draw is gone in under three years at an example rate of 7.5%. You borrow the down payment against the first house, and the first house's rent pays it back.

## Where the Blue Collar House Hack fits

My [Blue Collar House Hack](https://nobullshitloans.com/wealth/blue-collar-house-hack/) runs this move as a repeating cycle: open the line on the home you live in, use it for the down payment on your next primary residence, move in, and rent the old home at fair market rent. Every dollar of rental profit goes to the line until it is back to zero, and after at least a year living in the new home, you can do it again.

The line is the easy part. The real decision is whether you can carry two homes and whether the old one will rent for more than it costs. Run those numbers first, then size the draw to what the purchase actually needs.

## Frequently asked questions

### Do I have to sell my house to buy another one?

No. A line on the home you own can fund the down payment and closing costs on the next one while you keep the old home and its mortgage. The catch is qualifying, because the new lender counts the old home's payment unless the loan program lets its rent offset it. I run both versions before you shop, so you know which one you are living in.

### Do I have to tell the HELOC lender the money is for a down payment?

Yes. The application asks what the money is for, and the answer has to be the real one, along with whether you live in the home and what you plan to do with it. If you are not sure a detail matters, tell them and let them decide.

### Is a home equity loan better than a HELOC for a down payment?

For most of my clients, no. A fixed home equity loan charges principal and interest on the whole amount from the first payment, so it weighs more on your debt-to-income than an interest-only draw, and once you pay it down you cannot reuse it. My HELOC vs cash-out refinance page compares all three options side by side.

### What if my purchase falls through after I open the line?

Keep the line. Closing it inside the early-closure window, two years on the lines I see most often, means paying back the setup costs the lender covered, while leaving it open usually costs nothing. It will be there for the next house or the next emergency.
