How to Sell Your Car Yourself in Washington State

I wrote recently about why you should never trade in your car. The short version: the house always wins. Trade-ins give dealers multiple numbers to manipulate, and you lose thousands every time.

But I know what some of you thought: “Okay, fine. But selling a car myself sounds like a hassle.”

It’s not. Not even close. You can sell your car yourself in Washington State in a weekend.

I’m going to walk you through the entire process, start to finish—every step from detailing to title transfer at the DOL. And the payoff—keeping an extra $3,000–$5,000 that would’ve gone to a dealer—makes a few hours of work the best-paying side gig you’ll ever have.

Step 1: Get Your Car Ready

You don’t need to make your car perfect. You need to make it presentable.

Get it detailed. You can do this yourself or pay someone $200–$300 to do it. Interior and exterior. Vacuum the seats, clean the dash, wipe down the door panels. Wash and wax the outside. Clean the wheels. It’s amazing how much a clean car changes a buyer’s perception.

Handle the easy fixes. Replace burned-out bulbs. Top off fluids. If the check engine light is on for something minor like a gas cap, deal with it. You’re not trying to hide problems—you’re trying to show that you took care of the car.

Don’t fix major stuff. If the car needs a new transmission or has significant body damage, don’t dump money into repairs. Disclose it, price accordingly, and let the buyer decide. Honesty here works in your favor—buyers respect it, and you’ll attract people who are specifically looking for a project or a deal.

Remove your personal stuff. Registration, garage door opener, sunglasses, the random collection of napkins in the glovebox. Go through every compartment.

Step 2: Get It Inspected

This is the step that changes everything.

I covered why a seller inspection matters in detail in Part 1, but here’s how it fits into the practical workflow.

Before you list your car, have it professionally inspected by an independent third party. Not your buddy who’s “good with cars.” Not a quick look from a shop that’s going to try to sell you repairs. An independent inspection with documentation.

Here’s what you get and how you’ll use each piece:

• The inspection report tells you exactly what condition your car is in. No surprises. You know what’s good, what’s worn, and what needs attention. This lets you price confidently and answer any buyer question without guessing.

• The HD video walkthrough is your proof. Buyers can watch an inspector go through every system on your car before they ever contact you. Video doesn’t lie—and buyers know that.

• The Seller Certificate is your competitive edge. You get an image version to drop right into your listing photos and a PDF to print and tape inside your window. Both have a QR code that links to your full report and video.

When a buyer scrolling Facebook Marketplace sees a professional inspection certificate in your photo gallery, you’ve just separated yourself from every other listing on the page. You’re not “some guy with a car.” You’re a serious seller with nothing to hide.

A $275 inspection that helps you net $3,000–$5,000 more than a trade-in isn’t a cost. It’s a 10x return. (For context on why this matters, read about dealers vs. private sellers and who actually gets the better deal.)

Step 3: Set Your Price

Do your homework. This takes about 15 minutes.

Check Kelley Blue Book for your car’s private party value. Be honest about the condition.

Search Facebook Marketplace and Craigslist for similar cars in your area. Look at what’s actually listed (not what’s already sold). Sort by similar year, make, model, and mileage. This tells you what the market looks like right now.

Price slightly above what you’ll accept. If you want $12,000, list it at $12,500 or $13,000. Every buyer expects to negotiate a little. Build that room in.

If you have your inspection report, you can justify your price. “Here’s the full inspection—everything checks out” is a much stronger position than “trust me, it runs great.”

Step 4: Take Photos and Write Your Listing

Bad photos kill good cars. Don’t do this in your dark garage at 9 PM.

Photos:

• Shoot in natural light. Morning or late afternoon is best.
• Get all four corners, both sides, front, and rear.
• Photograph the interior: dashboard, seats (front and back), cargo area.
• Get the odometer, VIN plate, and any damage or wear spots.
• Under the hood, one clean shot.
• Include your Seller Certificate image. This goes in the photo gallery right up front—it’s the first thing serious buyers will look for.

You want 15–20 photos minimum. More is better. Buyers who can’t see what they’re looking for move on. Listing maximums vary (e.g. Facebook Marketplace is 10 images). If using Facebook marketplace, utilize their video feature (show car exterior while running, or panning shot of interior if it is exceptionally clean, etc.).

Your listing:

• Lead with the important stuff: year, make, model, mileage, price.
• Be specific about condition. “Runs great” means nothing. “New brakes at 85k, timing belt done at 90k, no leaks, cold AC” means everything.
• Disclose known issues. Seriously. If the paint is peeling on the roof, say so. Buyers who show up and find surprises walk away. Buyers who know about issues in advance have already decided they’re okay with them.
• Mention the inspection. “Professionally inspected by an independent third party—full report and video available via QR code on the certificate.”
• Include your asking price. “OBO” is fine. “$X FIRM” works if you’re priced right.

Where to list:

• Facebook Marketplace (largest audience in Spokane, free)
• Craigslist (still gets traffic, especially for cars)
• OfferUp (growing, worth the extra 5 minutes)
• Autotrader.com (not free but different audience)

List on all four. It takes 10 minutes each. Cast a wide net.

Step 5: Handle Inquiries and Test Drives

Your listing is live. Messages start coming in. Here’s how to sort the serious buyers from the time-wasters.

Screening inquiries:

• Serious buyers ask specific questions about the car. “Has it been in any accidents?” “When were the tires replaced?” “Can I see the inspection report?”
• Time-wasters send “Is this still available?” and disappear, or immediately offer half your asking price. (Sound familiar? The same red flags in used car listings apply in reverse.)
• If someone’s first message is a lowball offer, you can either counter or ignore. Don’t waste energy on someone who’s not serious.
• When buyers ask questions about condition, send them the link to your inspection report and video. This saves you time and builds instant credibility.

Test drives:

• Meet in a public place. A busy parking lot during the day is ideal. Some police stations have designated spots for exactly this.
• Bring someone with you. Don’t meet a stranger alone.
• Ask to see their driver’s license before the test drive. Take a photo of it.
• Verify they have car insurance. If they wreck your car on a test drive, you need them to be insured.
• Ride along on the test drive. Don’t hand your keys to a stranger and wait.

A note on safety: Trust your gut. If something feels off about a buyer, it’s okay to walk away. There will be other buyers.

Step 6: Close the Deal

You’ve found a buyer. They want the car. Here’s how to handle payment and paperwork.

Payment:

• Cash is simplest. Count it. If it’s a large amount and you’re uncomfortable carrying it, meet at your bank and deposit it immediately.
• Cashier’s check works, but verify it (and if you can, just ask for cash). Call the issuing bank (look up the number yourself—don’t call the number on the check) and confirm the check is legitimate. Fake cashier’s checks are the most common scam in private car sales.
• Never accept personal checks. They can bounce days later and you’ve already handed over the car.
• Never accept payment apps for large amounts. Venmo, Zelle, and Cash App transactions can be reversed or faked. Don’t risk it.

If the buyer needs financing: This is easier than you think (and for cars over $10,000, this happens most of the time). Most buyers can get a car loan from their bank or credit union for a private party purchase. Here’s the play:

• The buyer gets pre-approved for a loan from their bank or credit union.
• You meet at their bank. The bank verifies the title, cuts a check, and handles the paperwork on their end.
• You walk out with a bank check. Done.

Credit unions are especially good at this. They do private party auto loans all the time. Your inspection report actually helps the buyer here, too—lenders like documentation.

Complete a Bill of Sale: Washington State provides the Vehicle/Vessel Bill of Sale form. Both of you sign it. Include:

• Both parties’ names and addresses
• Vehicle year, make, model, and VIN
• Odometer reading
• Sale price
• Date of sale

Make three copies: one for you, one for the buyer, one for the DOL. A Bill of Sale isn’t technically required if the sale price and date are written on the title, but do it anyway. It protects both of you.

Step 7: Transfer the Title

This is the part that scares people, and it shouldn’t. Washington State makes this straightforward.

What you do as the seller:

1. Sign the title. In the “Assignment by Registered Owner” section on the back of the title. All registered owners must sign. If your title is lost, you’ll need a replacement from the DOL first—request one early, as standard processing takes 4–8 weeks (or pay an extra $50 for a Quick Title).

2. Complete the odometer disclosure. For vehicles model year 2011 or newer, you must record the current mileage on the title. This is federal law. Older vehicles are exempt.

3. Remove your license plates. This is critical and people forget it. In Washington, plates stay with you, not the car. You are legally required to remove them before the buyer drives away. You can transfer them to another vehicle you own or surrender them at a licensing office. If you don’t remove them, you’re liable for any parking tickets, tolls, or traffic camera violations the new owner racks up.

4. File the Report of Sale. You have 5 business days. The fee is $18. Do it online at License Express—it takes about 5 minutes. This officially notifies the state that you’ve sold the vehicle and protects you from liability.

5. Remove the vehicle from your License Express account if you have one.

What happens with the buyer:

• They need to get new plates and transfer the title within 15 days (or face a $50 penalty plus $2/day after that, up to $125 max).
• If they need to drive the car home without plates, they’ll need a trip permit ($36, valid for 3 days). They can get one at any vehicle licensing office.
• Pro tip: The DOL recommends meeting at a vehicle licensing office to complete the sale. It’s not required, but it makes things smooth—the buyer can handle their paperwork right there.

What about emissions testing? Washington eliminated emissions testing in 2020. There’s nothing you need to do here. One less thing to worry about.

What if you still owe money on the car? If there’s a lien on your title, you need to pay off the loan before you can transfer a clear title. Call your lender, get the exact payoff amount, and coordinate the timing with the sale. Some sellers pay off the loan with the sale proceeds—you can do this at the buyer’s bank or by having the buyer’s payment go directly to your lender. This is more common than you think, and banks handle it routinely.

You Can Do This in a Weekend

Here’s what the timeline actually looks like:

Saturday morning: Detail the car (or drop it off at a detailer Friday night). Schedule your inspection.

After the inspection: Set your price, take your photos, write your listings, post them on Facebook Marketplace, Craigslist, and OfferUp. Drop your Seller Certificate image right into the photo gallery. Total time: about an hour.

Over the next few days: Answer messages, schedule a test drive or two. Most cars sell within a week or two if they’re priced right and presented well.

When you find a buyer: Meet up, handle payment, sign the title, file your Report of Sale online. You’re done.

Total effort: maybe 4–5 hours of actual work spread over a week. For $3,000–$5,000 more than you’d get from a trade-in, that’s $600–$1,000 per hour for your time.

Stop Leaving Money on the Table

Every car that gets traded in is money transferred from a regular person to a dealership. Every one. The convenience of a trade-in is a story dealers tell you because it benefits them, not you.

Selling your car privately in Washington State is not complicated. The paperwork is a few forms. The process is a few steps. The result is thousands more dollars in your pocket.

Get your car inspected. Take your photos. Post your listing. Keep your money.

Frequently Asked Questions

What paperwork do I need to sell a car in Washington State?

You need your vehicle title (signed in the assignment section), a Bill of Sale (WA DOL Form TD-420-065), and you must file a Report of Sale within 5 business days ($18 fee, can be filed online at License Express). For vehicles model year 2011 or newer, you also need to complete the odometer disclosure on the title.

Do I need to remove my license plates when selling a car in Washington?

Yes. In Washington State, license plates stay with the seller, not the car. You are legally required to remove them before the buyer drives away. You can transfer them to another vehicle you own or surrender them at a licensing office. Failure to remove plates leaves you liable for parking tickets, tolls, and traffic camera violations.

Do I need an emissions test to sell a car in Washington State?

No. Washington eliminated its emissions testing program on January 1, 2020. There is no smog check, emissions test, or vehicle inspection required to sell, buy, or register a vehicle in Washington State.

How long does it take to sell a car privately?

Most well-priced cars with good photos and documentation sell within one to two weeks. The preparation work—detailing, taking photos, writing listings—takes about 4–5 hours total. If you have a professional inspection and Seller Certificate, you’ll attract serious buyers faster because the trust problem is already solved.

What’s the safest way to accept payment for a private car sale?

Cash is the safest option. For larger amounts, meet at your bank and deposit immediately. Cashier’s checks work but should be verified by calling the issuing bank directly. Never accept personal checks, and avoid payment apps like Venmo or Zelle for large transactions—they can be reversed or faked.

Can a buyer finance a private party car purchase?

Yes. Most banks and credit unions offer private party auto loans. The buyer gets pre-approved, you meet at their bank, and the bank cuts a check directly. Credit unions handle these routinely. Having a professional inspection report can actually help the buyer get approved, since lenders like documentation.
