Most of what is written about Facebook Marketplace and cars is about buying. The flipper’s problem is the other end: the car is reconditioned, the money is in it, and every day it sits is a day the capital is not working. Cox Automotive had cars under $15,000 at 29 days’ supply in August 2026, which means a correctly priced cheap car in a normal market should be gone inside a month, and the good ones inside a week.
Here is the week, day by day. It assumes the car is ready, because a car listed before it is ready produces messages you cannot act on and a listing that goes stale.
Day 0: the price, before anything else
Everything downstream depends on this number, and it is set by the market, not by what you need.
Open Marketplace as a buyer would. Search the make and model, set the distance a buyer would travel for a car at that price, and sort by the listings a real person sees. Write down the three to five cars that are genuinely comparable: year band, mileage, condition. Yours needs to be at or just under the lowest of them for a car in equal condition, because the cheapest of four identical cars is the one that sells this week and the others wait.
If that number is below your cost, the mistake was made at the buy and this is the wrong place to fix it. How to price a car to flip is the walk-back that prevents it; today the choice is between a thin margin now and a thinner one in six weeks. Days on the lot has the arithmetic on why waiting rarely pays.
Set the price to end in a round hundred, not a 999. Marketplace buyers filter by price bands and a car at $8,400 shows up in a search capped at $8,500; a car at $8,499 reads as a trick.
Day 0: twenty photos in good light
The first photo decides whether anyone taps. The other nineteen decide whether they message.
Clean car, early morning or late afternoon light, a plain background without other cars or a house number. Front three-quarter as the first photo, then the full walk round, every seat, the odometer, the dash with the engine running and no warning lights showing, the tires with the tread visible, under the hood, the trunk with the spare, and every flaw you would otherwise be asked about: the scuffed bumper, the worn bolster, the chip in the glass. A flaw you show is a detail; a flaw a buyer finds is a renegotiation.
No filters, no wide-angle distortion, no photos from the listing you bought it from. Twenty honest photos read as a seller with nothing to hide, which is the entire reputation a private seller has.
Day 0: a listing that answers the five questions
Buyers ask the same five things, and a listing that answers them in the first lines gets fewer messages and better ones.
Why are you selling? Say it plainly: bought it, replaced the brakes and tires, detailed it, moving it on. Is the title clean and in your name? Say which. What has been done? List the parts, with the month. What is wrong with it? List it; there is always something. Is the price firm? Say so, or name the lowest you will take, and say the car goes to the first person who shows up with the money.
Then the facts: year, trim, engine, mileage, number of keys, recent service, tire brand and depth. Then one line on how to buy: cash or cashier’s check, test drives at a named public place, paperwork done at the bank. No life story, no capital letters, no “serious buyers only”, which attracts the opposite.
Post it in the evening when the feed is busiest, and post the same listing to two or three local buy-and-sell groups where that is allowed.
Days 1 to 2: the message filter
The first 48 hours bring the most messages and the worst ones. The job is to sort them in seconds without being rude to the few real buyers.
Every message gets the same reply: thanks, the car is available, when can you come and see it? People who answer with a day and a time are buyers. People who answer with a number are not yet, and the second reply to them is the price line from the listing, once. People who ask whether it is still available and vanish were never there.
Lowballers are not insults, they are noise. A flat “the price is firm, happy to show it to you” ends most of them, and the ones who come anyway often pay the asking price once they have seen the car. The one thing never to do is drop the price in a message; the price moves on the listing, for everyone, or it does not move.
Keep a short list of the serious ones with their times, and confirm each the morning of. The flipper who runs the week well is scheduling two or three viewings for Day 3, not answering forty messages on Day 1.
Day 3: the viewing and the test drive
A public place with cameras, in daylight, with a second person if you can. A bank car park is ideal because the paperwork can be done inside afterwards. Photograph the buyer’s licence before the test drive and go with them. Have the title, the bill of sale and the service receipts in a folder on the seat; a seller who has the documents ready is a seller who is not hiding anything.
Let the car speak. Point out the flaws before they are found, because you already listed them and a buyer who finds one you did not mention stops trusting the rest. Know your total cost and your floor before they arrive, which is what the two numbers on every car are for, and do not renegotiate in the car park. If they want to think, say the car goes to the first person with the money and give them the evening.
Days 3 to 5: the money
Nothing moves until the money is real. Cash counted at the bank, with the teller. A cashier’s check verified by calling the issuing bank on a number you looked up, not one printed on the check. A transfer that shows as cleared in your own banking app, not on their screen. Personal checks and reversible payment apps are not payment until they have settled, and a flipper who hands over keys against a screenshot has given away a car.
If the buyer is financing, the lender pays you and the timeline is theirs; get the lender’s name and let them tell you how they pay sellers. If the buyer pays more than $10,000 in cash and you are in the business, that is a Form 8300 within 15 days and a written statement to the payer by the following January 31. Car flipping taxes covers what the sale means for the return.
Take a deposit only against a short, written hold, and only once; a car “held” for a week for a buyer who never returns is a week the car was off the market.
Day 5 to 7: the paperwork that protects you
A private sale needs three documents and one habit.
The title, signed over correctly to the buyer with the odometer reading, in the fields the state uses, with no corrections. A title with a crossed-out name is a title the DMV may reject, and a rejected title is a buyer at your door. The title has to be in your name; selling a car you never titled to yourself is title jumping, which is an offence in most states and is covered in title jumping and curbstoning.
A bill of sale, two copies, with both names and addresses, the VIN, the mileage, the price, the date and the words “sold as is, no warranty”, signed by both. It is your record of the sale price for the books and your protection against the buyer who calls in a month about the transmission.
The notice to your DMV that you have sold the car, which most states require within a set number of days, and which is what stops the buyer’s parking tickets and tolls arriving at your address. Florida, for one, requires the seller to notify the department within 30 days.
The habit: the plates come off before the car leaves, if your state’s plates stay with the seller, and the sale date and price go into your records the same day, because the real profit on the car and the days it took are only true if they are written down when they happen.
If you sell or offer more than five used vehicles in twelve months, the FTC Used Car Rule requires a Buyers Guide displayed on the car and given to the buyer, with the contract referring to it. It is a printed form and it is not optional at that volume.
What the week tells you about the buy
A car that sells on Day 4 at the asking price was bought right. A car that needs a price cut on Day 10 was bought $300 too high, or was the wrong car for the market, and the week just told you which. Either way the lesson is only useful if it is recorded against the car: sale price, date, days held, real profit.
That record is what the free car flipping spreadsheet keeps, and what the Deelary app keeps on the phone you took the photos with, with the receipts attached and the days counted. After six cars it will tell you which lane sells in a week and which one sits, and the next listing starts from a better buy.
Frequently asked questions
Why does a car sit on Facebook Marketplace?
Almost always the price, then the first photo, then the description. Buyers scroll a feed of near-identical cars and give each one about a second. If yours is not the cheapest of the four comparable cars on the screen, or its first photo is worse, it does not get the tap, and a car that does not get tapped does not get messages.
How should I price a flipped car on Marketplace?
At or just below the lowest live comparable for a car in equal condition, within the distance a buyer would drive. Not the guide value, not what you need to make. If the number the comparables give you is below your cost, the problem was the buy price, and holding out for more usually costs more in days than it recovers in dollars.
How many photos do I need?
Twenty or more, taken in good light with the car clean, and the first one chosen as the one that would stop your own thumb. Every angle outside, every seat, the odometer, the dash with the engine running and no warning lights, the tires, under the hood, the trunk, and any flaw you would otherwise be asked about. Fewer photos reads as something to hide.
How do I deal with lowballers and time wasters?
With a filter in the listing and a script in the messages. State the price is firm or state the lowest you will take, say the car is sold to the first person who shows up with the money, and ask every enquirer when they can come and see it. People who answer with a day and a time are buyers. People who answer with a number are not, yet.
Should I accept cash, Zelle, cashier's check or a loan?
Cash counted at a bank, a cashier's check verified at the issuing bank, or a transfer confirmed in your own banking app before the keys move. Personal checks and payment apps that can be reversed are not payment until they have cleared. If the buyer is financing, the lender pays you and the timeline is theirs. Cash over $10,000 in a trade or business means a Form 8300 within 15 days.
What paperwork does a private sale need?
A title correctly signed over to the buyer with the odometer reading, a bill of sale with both parties, the VIN, the price, the date and "sold as is", and, in most states, a notice from you to the DMV that you sold it. Past five used vehicles sold or offered in twelve months, the FTC Used Car Rule requires a Buyers Guide on the car as well. The state rules differ, so check yours before the first sale.
