Can I sell my car and borrow against my house at the same time?

Yes. Selling first shrinks what you borrow: every $1,000 less saves about $217 of interest over a 5-year payoff at our example rate of 8.00%.

Is HELOC interest tax-deductible if I use it for bills?

No. The IRS lets you deduct home equity interest only when the money buys, builds or substantially improves the home that secures the loan, and only if you itemize deductions.

Need cash fast? Selling your car vs. borrowing against your home

A junk car sale can put cash in your hand within days and leaves you owing nothing, but our estimate for a non-running junk car is about $205 to $520, depending on its size. Borrowing against your home can raise far more. It also takes longer, costs interest and fees, and makes the house the collateral.

How fast does each option put cash in your hand?

Peddle, the buyer we partner with, says its process from offer to payment typically takes 2 to 5 days and sometimes finishes the same day. Take a check at pickup and you are paid on the spot. Peddle pays us a commission when you sell through it.

Borrowing against a home runs through an application, a review of your credit, income and the home's value, and a closing. Navy Federal, a credit union open to the armed forces, the DoD, veterans and their families, currently estimates 30 to 40 calendar days to close a new home equity loan or HELOC once it has your application. Federal rules also set minimum waits that no lender can shorten:

Home equity loan or cash-out refinance: the lender must deliver your Loan Estimate no later than the seventh business day before closing.
HELOC, home equity loan, cash-out refinance and most reverse mortgages on your primary home: you can cancel until midnight of the third business day after closing, and the lender may not release the money until that window has passed.
Reverse mortgage (HECM): you must first get counseling from a HUD-approved reverse mortgage counseling agency.

For these rules a business day is every day except Sundays and federal holidays. So on a home equity loan against your primary home at least 10 business days pass between the Loan Estimate and the first dollar: about two weeks at the earliest. You can waive the waits only for a bona fide personal financial emergency, in a dated statement describing it and signed by every borrower and owner. Preprinted forms are not allowed.

What does each option cost?

Selling costs you the car. Peddle says there are no fees and towing is included, so the offer you accept is what you are paid, if the car matches how you described it. Impound or storage fees to release the car, and a notary if your state requires one, are on you. Check what the car is worth first with our junk car value calculator.

Borrowing costs interest for as long as you carry a balance, plus fees. A HELOC rate is usually variable: an index such as the U.S. prime rate plus a margin the lender adds, so your payment moves with the index. To see what a line would cost at your own balance and rate, run the numbers in Home Equity Calcs. Home Equity Calcs is a free calculator site from the team behind JunkCarValue.com.

The CFPB lists the fees a HELOC can carry: an application fee, appraisal and other closing costs, an annual or membership fee, an inactivity fee, and a cancellation fee for closing the line early, usually within the first two or three years. Some real terms: Bank of America charges a $450 early closure fee on most lines closed within 36 months, and PenFed charges $99 a year.

Lines also have minimum sizes far above what a junk car brings. Navy Federal's start at $10,000 and Figure's at $15,000, while PenFed's start at $25,000, which is also Bank of America's usual minimum.

One tax point: if the money pays personal bills or buys a personal car, the interest is not deductible. The IRS allows the deduction only when the funds buy, build or substantially improve the home that secures the loan, and only if you itemize.

Worked example: you need $10,000 this month

Say you own a midsize sedan that no longer starts and a home with equity. With a clean title and its catalytic converter, our estimate for the sedan is $225-$280: about 3% of the $10,000, paid within days, with nothing owed afterward.

Below is a $10,000 HELOC draw at an example rate of 8.00%: the prime rate of 7.00% on October 2, 2026, plus an example margin of 1 point. Your lender's margin will differ.

Repayment path (example rate)	Monthly payment	Interest paid
Pay it off over 5 years	$202.76	$2,166 in total
Interest only for 10 years, then repay over 20	$66.67, then $83.64	$18,075 in total
Interest only after a 2-point rate rise (10.00%)	$83.33	$1,000 a year

Paying only the interest is cheap each month and expensive overall: that path costs $15,909 more interest than the 5-year payoff. Every $1,000 you raise by selling something instead of borrowing it saves about $217 of interest on the 5-year path. For a shortfall of a few hundred dollars the car may be all you need.

For a gap of a few thousand dollars, below the smallest line among the lenders above, the CFPB's comparison table lists sources that leave your home out of it. A personal line of credit needs solid credit and, like a credit card, charges a higher rate than a loan secured by your home. A 401(k) loan is generally capped at 50% of your vested balance or $50,000, whichever is less, and if you leave or lose your job you repay it in full or pay taxes and penalties. Borrowing from friends or family means less waiting and paperwork, at some risk to the relationship.

Five ways to tap home equity, and who each one fits

Option	How it works	Who it fits
HELOC	A credit line you draw from as needed. Some plans allow interest only while you draw; then principal and interest, often over 10 to 20 years	Costs that arrive in pieces, with room for a payment that will rise
Home equity loan	One lump sum, repaid in equal payments, typically at a fixed rate	One known bill and a need for a steady payment
Cash-out refinance	A new, larger mortgage replaces yours and you take the difference; one payment on the whole new balance	Owners whose current mortgage rate is no lower than today's rates
Home equity investment	A lump sum from a company. No monthly payments; one settlement, based partly on the home's value, at the end of the term or at sale	Owners turned down for a HELOC or refinance who accept a higher cost
Reverse mortgage (HECM)	Borrowing against the home at 62 or older. No monthly mortgage payments; the balance grows and is repaid when you no longer live there, usually by selling	Owners 62 or older who plan to stay and can keep paying taxes and insurance

HELOC: the CFPB gives 10 years as an example of a draw period, and some plans demand the whole balance at once when it ends, a balloon payment.

Cash-out refinance: the CFPB notes that closing costs are generally higher, it may take longer to pay off your mortgage, and the new rate may be higher than your current one. For loans it buys, Fannie Mae generally requires the first mortgage being paid off to be at least 12 months old and a borrower to have been on title for at least six months.

Home equity investment: the CFPB found these contracts are often more expensive than traditional home-secured borrowing, with origination fees typically much higher than a HELOC's. You still pay property taxes and insurance. The term is often 10 to 30 years, the single repayment can run into the hundreds of thousands of dollars, and an owner who cannot pay it may have to sell or face foreclosure.

Reverse mortgage: you must live in the home as your principal residence, keep it in good condition and owe no federal debt such as unpaid income tax, though the loan can pay that debt off.

What can go wrong when your home is the collateral?

You could lose the home. The CFPB's advice is to consider a HELOC only if you are confident you can keep up with the payments.
The payment jumps when the draw period ends. The CFPB says monthly payments are often significantly higher once repayment starts.
The rate floats. In the example above, a 2-point rise adds $16.67 a month to the interest-only payment on $10,000.
The line can shrink. Federal rules let a lender freeze or cut a HELOC while the home's value is significantly below its appraised value, or when it reasonably believes a change in your finances will keep you from repaying.

How to decide: a short checklist

Put a date on the need. A home equity loan or cash-out refinance on your primary home cannot pay out until at least 10 business days after the Loan Estimate, about two weeks at the earliest, unless you waive the waits for an emergency.
Price the car and compare buyers before you borrow: see who pays the most for junk cars.
Check the gap against lenders' minimum line sizes. If you need a few hundred dollars and lines start at $10,000 or more, you would put a lien on your home for a sum the car sale may cover.
Test the payment at a rate 2 points higher and after the draw period ends. If either strains your budget, borrow less.
Ask whether the money will go into the home. Only then can the interest be deductible.
If you are 62 or older and plan to stay, the required counseling session is the place to ask whether a reverse mortgage fits.
Offered a home equity investment? Ask for the settlement amount under several home-price scenarios and set it beside a HELOC's total interest.

Frequently asked questions

It can be. The seven-business-day wait before closing covers home equity loans and cash-out refinances, and a HELOC is a line of credit. Both share the three-business-day right to cancel on a primary home.
