Buying and Selling in Colombia: Marketplace Culture, the 'What Is Your Minimum Price' Rule, and the Scams That Will Drain Your Bank Account

In Colombia the first message a buyer sends on Facebook Marketplace or MercadoLibre is almost always “¿Cuál es tu precio mínimo?” (What is your minimum price?). Those four words carry the whole negotiation culture. You will hear them in Bogotá, Medellín, Cali, and the smaller towns. Knowing why the question shows up, where Colombians actually buy and sell, and which tricks turn a normal chat into a bank-account drain is the difference between a good deal and losing access to your own banking app for three days while a courier walks off with your phone.

This post covers the culture first, then the platforms, then the five scams you will run into if you stay here long enough.

Where to look first

How the “Minimum Price” question actually works

Colombians lead with the minimum price because it is polite and efficient. It is not an insult and it is not a low-ball. It is a buyer asking for your floor so they can decide if the item is worth their time. The seller’s answer sets the bargaining range. From there, the conversation is fast.

The standard practice is to list at the honest price plus a 30,000 to 50,000 COP haggling margin. A used bike worth 250,000 COP gets posted at 280,000 to 300,000. The buyer sends a number underneath your asking price, and the two of you settle somewhere in the middle.

Doubling the price to “leave room” backfires. MercadoLibre’s algorithm pushes overpriced listings down, and Colombian buyers compare a dozen items before they message anyone. If a phone identical to yours is selling at 800,000 COP elsewhere and you posted 1,400,000, nobody messages, nobody negotiates, and your listing dies on page four.

When the question arrives, answer with a real number. Saying “haz tu mejor oferta” (make your best offer) signals that you do not know your own market and invites everyone with 50,000 pesos in their pocket to message you. Pick a floor you would actually accept, drop it 5 to 10 percent below the listing price, and reply directly. The serious buyers respect that. The time-wasters move on to the next listing, which is exactly what you want.

Where Colombians actually buy and sell

Facebook Marketplace runs the volume. It is free, instant, and lives on the same app where most Colombians already spend an hour a day. You will find apartments, sofas, refrigerators, motorcycles, used iPhones, and entire household liquidations from expats moving home. It is also where almost every scam in this article happens, because there is no escrow, no buyer protection, and no real verification on either side.

MercadoLibre is the formal alternative. It charges sellers a fee, but in exchange you get Mercado Pago, which holds the buyer’s money until delivery is confirmed. For shipped goods, electronics, and anything where the buyer and seller are not in the same city, this is the right tool. The fee is real, but so is the protection. Heavy items like furniture, appliances, and motorcycles still mostly move through Marketplace because shipping a sofa across Bogotá traffic does not really work.

HeyColombia (heycolombia.com) is the newer option. It targets expats specifically and lists real estate, vehicles, electronics, and jobs. Contact is direct, there is no escrow, and the risk profile is identical to Facebook Marketplace. The advantage is that the audience skews toward foreigners selling nearly-new things on the way out of the country: furniture from a two-year-old apartment in Laureles, a barely-used MacBook from someone moving back to Berlin. The disadvantage is the same audience tends to be less familiar with local scam patterns, so fraudsters are starting to work the platform actively.

For cars and motorcycles, TuCarro (tucarro.com.co) is the default. It is owned by MercadoLibre, runs the same buyer-protection model, and lists every dealer and most private sellers in the country. If you are buying a used car, start there before Facebook, where the same vehicle often gets listed at a higher price by a flipper.

Honorable mentions. OLX Colombia still runs but its share has shrunk. FincaRaiz and Metrocuadrado are the right tools for actual rentals, not Marketplace. For used furniture and household stuff, MercadoLibre’s Hogar and Segunda Mano categories cover most of it. Each platform has its lane, and using the right one cuts your scam exposure in half before you start.

Scam 1: The electronics-seller trap

This is the load-bearing scam. If you sell anything worth more than 500,000 pesos in Colombia, this will eventually arrive in your inbox. Knowing the shape of it costs nothing and saves your phone, your laptop, and three days of access to your own bank account.

Setup. You list a phone or laptop on Facebook Marketplace. A buyer replies fast, says they are “out of town” or “working in another city,” and asks to send a mensajero (courier) to pick up the item. They will pay first by Nequi or Bancolombia “before the courier arrives, so you feel safe.”

The fake screenshot. They send a polished receipt. Green check, the right amount, a transaction reference, the timestamp. It looks identical to a real Nequi or Bancolombia confirmation, because the apps do not always push real-time inbound notifications to the receiver. Sellers learned to trust screenshots because that was the only proof available, and scammers learned to forge screenshots because nobody was checking.

The cédula ask. “Para confirmar el envío, ¿me pasas tu número de cédula?” (To confirm the shipment, can you give me your ID number?). It sounds reasonable. The buyer claims the courier needs it for the package, or the bank needs it to “release” the transfer. It is the trap.

What the cédula actually does. With your cédula plus your WhatsApp number, a scammer calls the bank’s fraud-prevention line posing as you. They claim unauthorized activity, request a precautionary block, or push a security reset. Your banking app stops working for 24 to 72 hours while the bank “investigates.” By the time you log back in to confirm that no money ever arrived, the courier has been gone for hours and your phone is in another city.

The verification rules. Read these once and screenshot them.

1. Open the Nequi or Bancolombia app yourself. Check the Movimientos tab. If the app shows nothing, the money is not there. The screenshot is not proof.
2. Use Nequi’s QR Verificador feature to validate any receipt. Nequi support: 300 600 0100 for consumers, 300 600 0200 for merchants.
3. Never give a buyer your cédula. No legitimate transfer needs it. All a buyer needs to send you money is your Nequi phone number or your Bancolombia account number.
4. No couriers. If the buyer cannot come in person, walk away. Real buyers in Colombia show up. The “I am traveling” excuse is the single most reliable scam signal in the entire marketplace.
5. Cash on pickup in a centro comercial lobby during daylight, or Mercado Pago escrow for shipped items. Anything else is optional, and optional means risky.

Following those five rules makes this scam structurally impossible. The fraudsters need you to skip step one or step three. If you do neither, they move on to the next seller.

Scam 2: Fake rental listings

This one targets expats hard, especially in Medellín (El Poblado, Laureles) and Bogotá (Chapinero, Usaquén). The pattern is consistent: a beautiful two-bedroom listed at 30 to 40 percent below market, the “owner” is currently abroad and cannot show the apartment in person, but they need a deposit by Nequi or Western Union to “hold” it and “mail you the keys.”

There is no apartment. Or there is an apartment, and it belongs to someone else who has no idea their photos are being used.

Defense. Never wire a deposit before viewing the property in person. Reverse-image-search the listing photos, the same images often appear on three or four unrelated rental sites across Latin America. Use FincaRaiz, Metrocuadrado, or a verified inmobiliaria (real-estate agency) for actual rentals. Marketplace and HeyColombia are fine for finding leads, but the lease, the deposit, and the keys all happen in person, with a Colombian who can be located if something goes wrong. The Colombia Mágico rental guide at /blog/renting-apartment-colombia/ walks through the verification process step by step.

Scam 3: Fake pet adoption

Listings appear for purebred puppies, usually Pomeranians, French Bulldogs, or Golden Retrievers, at prices that are obviously below market. The “breeder” demands an urgent payment to “secure” the puppy before another buyer takes it, and then a second payment for transport from another city. There is no puppy.

Defense. Visit the litter in person and meet at least one parent dog before any payment changes hands. A real breeder welcomes the visit, a scammer invents reasons you cannot come. If the seller refuses an in-person visit, treat it as a confirmed scam and move on.

Scam 4: WhatsApp redirect and fake-buyer prepayment

Two flavors of the same playbook.

The redirect. A listing has no price. When you ask, the seller replies “te paso info por WhatsApp” (I’ll send you the info on WhatsApp). The conversation moves off Facebook, where the platform’s reporting tools and profile history live, and onto a chat where the scammer can push phishing links, fake payment portals, or requests for personal data without leaving a trail.

The fake-buyer prepayment. A buyer messages, offers full asking price instantly, and explains they will pay through “secure shipping” or a “transaction insurance” service that requires you to pay a small fee first, with the promise that the fee gets reimbursed inside the transfer. The fee is the scam. The buyer never existed.

Defense. Keep negotiation on the platform until pickup is locked in. Never pay anything to receive money. Treat any unsolicited link as hostile, especially links shortened with bit.ly or shipping-service domains you do not recognize. Real buyers do not ask you to fund their delivery insurance.

Scam 5: Bank impersonation calls

Closely related to scam 1’s cédula angle, often run as the second move after a successful cédula harvest. The phone rings. A calm voice claims to be from “Bancolombia fraud prevention” or “Nequi seguridad,” says they detected a suspicious charge on your account, and asks you to confirm your cédula, read the OTP that just landed on your phone, or install a remote-support app like AnyDesk so they can “fix” the issue.

Defense. Hang up. Call the number printed on the back of your card. Banks never ask for OTPs over the phone, and they never ask you to install remote-support software. The OTP exists specifically so the bank does not need to ask, your input on the screen is the confirmation. Anyone asking for it is not the bank.

Red flags checklist

Before you reply to a message, scan it for any of these. They tend to cluster, so a single red flag is reason to pause and a second is reason to walk away.

• Generic “¿Sigue disponible?” (Is it still available?) and nothing else
• No price listed, message says “WhatsApp para info” (WhatsApp for info)
• Brand-new profile, few friends, AI-looking photo
• Item priced 30 to 60 percent below market with urgency, “vendo hoy” (selling today)
• Buyer wants a mensajero (courier), refuses to come in person
• Any request for cédula, OTP, “insurance” fee, “shipping” fee, or up-front transfer
• Pressure to move payment off Mercado Pago or off the platform

How to protect yourself

• Meet in person, daytime, in a public location: a centro comercial lobby, a bank vestibule, or in front of a CAI (Centro de Atención Inmediata, the local police kiosk).
• Never pre-pay. Demand cash on pickup, or Mercado Pago escrow for shipped items.
• Never trust a screenshot. Open your own app and check the Movimientos tab.
• Verify electronics work in front of the buyer. Power, screen, connectivity, all tested before you let go of the device.
• Choose counterparties whose profile is older than one year and shows real local activity (posts, comments, friends from your city).
• Refuse gift cards, crypto, and foreign wire services. They are untraceable, which is exactly why scammers prefer them.
• Buyer side: same rules in reverse. Sellers asking for a Nequi deposit to “hold” an item are running the inverse playbook.

If you already got hit

Move fast, in this order.

1. Call Bancolombia or Nequi immediately to freeze the affected accounts. Use the number printed on the back of your card, or 300 600 0100 for Nequi consumer support. Speed matters, the first 30 minutes after a fraud event are when most of the money is recoverable.
2. File a suplantación de identidad (identity impersonation) alert with all three Colombian credit bureaus: CIFIN, DATACRÉDITO, and PROCRÉDITO. This stops the scammer from opening cellphone plans, cable accounts, or loans in your name over the next few weeks, which is the standard follow-on move after a cédula compromise.
3. Report the incident to Policía Nacional via the CAI Virtual portal (caivirtual.policia.gov.co), and file the formal complaint via the Fiscalía’s “A Denunciar” portal (adenunciar.policia.gov.co). Save the case number, the bank will ask for it later when you dispute charges.
4. Plan for cash spending. Realistic timeline for getting your account unfrozen is days, not hours. Keep receipts for everything during the freeze, you will need them if the bank disputes the timeline.
5. Tell the truth on the dispute form. If a transfer was voluntary even by manipulation, say so, do not claim it was unauthorized. Lying on a bank dispute is the fastest way to lose recovery rights and damage your credit profile, and the bank will figure it out.

The system is slow, but it works if you start it within the first hour.

A working marketplace despite the scams

Colombia’s secondhand economy is enormous and mostly works fine. The cultural openness around price negotiation is genuinely a feature, a five-minute Facebook Marketplace conversation can land you a sofa for half what Homecenter charges, and most of the people you meet are exactly who they say they are.

The scams are concentrated, predictable, and avoidable if you know the pattern: courier pickup, advance “transfer,” screenshot proof, cédula request, or any pressure to leave the platform. Spot one of those, walk away. The good deals will still be there tomorrow.
