Working With Buyers Who Have a Bank or Credit Union Preapproval

The buyer walks in holding a printout from a credit union. The floor rep smiles. The desk frowns. Someone says "we can probably beat that" before anyone has read the expiration date, the vehicle conditions, or whether the amount even covers this car plus tax. Twenty minutes later the buyer believes you tried to take their financing away, and the credit union believes you tried to rewrite their member's deal. That is not a product problem. That is a store that does not know how to work with buyers who have a bank or credit union preapproval.

Outside financing is not an insult. It is a buyer who already did work. Marketplace makes this more common, not less: people message you after they talk to their own bank, because they do not want a surprise in F&I. If your process treats the letter as a nuisance, you will lose people who were ready to buy the unit at the listed cash price.

This article is for GMs, F&I managers, and sales reps. It covers what a preapproval usually is and is not, what to ask in the Marketplace thread, how to verify on arrival, and how to present dealer financing as an option rather than a wrestling match. It is operational guidance, not legal advice. Lender contracts, dealer-reserve practices, and advertising rules vary. Confirm your handling of outside financing and any comparison talk with counsel and your lenders.

Treat the Preapproval as Information, Not as a Verdict

A preapproval is a lender's conditional willingness to extend credit under stated limits. It is not a blank check, and it is not automatically the best structure for this vehicle. Your job is to read it, not to compete with it in the driveway.

What you still do not know

Until you look, you may not know:

• The expiration date.
• The maximum amount financed, and whether tax, title, and fees are included in that cap.
• Any vehicle year, mileage, or type restrictions.
• Whether the buyer is looking at a payment, a rate, or a total they misunderstood.
• Whether a trade payoff will blow the cap.

What you should not do in the first five minutes

• Talk the buyer out of their credit union as a reflex.
• Promise you will "beat" the letter.
• Ignore the letter and start a full application as if they said nothing.
• Tell them the preapproval means the car is already theirs.

What "working with" actually means

It means you can sell the car at the listed cash price to a buyer who funds through their own institution, subject to your normal deal process, payoff timing, and any store policies on third-party lenders. It also means you can, with their permission, show a dealer-arranged option if you have one. Those are two paths. They should sound like choices, not like a correction.

Price display still matters: the figure in the listing should be a cash price the desk will honor whether the buyer uses a credit union or dealer financing. See Cash Price vs Financed Price in Vehicle Listings.

What to Ask a Preapproval Buyer in the Marketplace Chat Before They Drive Over

The thread is the cheapest verification step. You are not asking them to upload account numbers.

Questions that save the appointment

• "Is the preapproval from a bank or credit union you already use?"
• "Does the letter name a maximum amount, and does it include tax and fees or only the vehicle?"
• "Is it still in date, as far as you know?"
• "Are there year or mileage limits written on it?"
• "Do you want to use that lender, or do you want us to look at options as well?"

If they do not know the answers, ask them to bring the letter or the lender portal details to the visit. Do not reconstruct the offer from memory in chat.

What not to collect in Messenger

Do not ask for a photo of the full letter if it contains account numbers, Social Security numbers, or other sensitive data. Ask them to bring it. If they paste a screenshot, tell them not to send more, and handle the document in person under your normal privacy process.

Align the unit to the cap without diagnosing them

If they tell you a maximum amount that is clearly below this vehicle's cash price plus typical costs, you can say so in factual terms: "The listed price on this one is X before tax and fees. If the preapproval cap is below that, we should look at the letter together or look at other units." That is arithmetic, not a credit lecture.

When they also want a monthly figure based on the letter, do not guess. Use the same discipline as Answering Monthly Payment Questions Without Guessing. Their letter is their lender's math, not yours, until the desk has read it.

A Lot Process for Preapproved Buyers

Write this so every shift runs it the same way.

1. Greet and inspect the letter with the buyer present

Read expiration, amount, and conditions out loud in plain language. If something is unclear, say it is unclear. Do not bluff.

2. Run the vehicle against those conditions

Year, mileage, body style, title status, and any "new vs used" language. If the unit fails a written condition, stop and either pick another unit or have the buyer call their lender. Do not hide a mismatch until contracting.

3. Structure the cash deal first

Price, fees, trade, payoff, taxes as they apply. The preapproval sits on top of a clean cash structure. If the structure does not fit the cap, you now have a fact, not a feeling.

4. Offer a second path only if it is real

If the store can arrange financing, present it as an alternative they can compare, not as a rescue. Do not disparage their credit union. Do not invent a comparison payment. If they want a comparison, it happens with numbers the desk can support, after any applications they choose to make.

5. Be explicit about timing

Credit union drafts, payoff windows, and weekend funding delays are how Saturday deliveries slip. Tell them what usually has to happen before keys, based on how your store actually funds third-party deals. Do not promise same-day delivery if your process cannot do it.

6. Keep the inventory honest while you wait

If the deal is pending funding, the unit cannot stay advertised as a wide-open Marketplace listing. Mark status correctly. A second buyer who messages "is this available?" during a credit-union wait is how you create two angry people.

Desk Habits That Make Preapproved Buyers Stay

Stop treating outside money as lost gross

Some deals will have less finance reserve. That is not permission to sour the greeting. A unit that turns is still a unit that turned. If your pay plan punishes outside financing so hard that reps hide the letter, fix the pay plan.

One person explains the comparison

If a comparison is going to happen, it should be F&I or a trained manager, not three reps with three stories. Floor reps should know how to receive the letter and how to not compete with it.

Document what you received

Note the lender name, expiration, stated cap, and any vehicle restrictions in the deal jacket process you already use. If the buyer later says "you ignored my letter," you want a record that you read it.

Do not dual-pull as a default

Applying with dealer lenders "just in case" can be a legitimate buyer choice. It can also be an extra inquiry they did not want. Ask. Explain. Do not sneak.

Edge Cases

The letter is a prequalification, not a preapproval

Language varies. If the document is clearly exploratory, say so: more work remains. Do not inflate it into a guarantee.

The amount is enough for the car and not for the car plus the trade payoff

Name the gap. Options include a larger down payment, a different unit, paying off the trade separately, or walking. Guessing a blended payment in chat is how this edge case explodes.

The credit union will not book your store as a dealer

Some institutions send a check to the member or have funding rules that slow delivery. Know your store's policy for those cases before you promise a weekend delivery.

Two buyers, one letter

If only one name is on the preapproval, the other person is not automatically on the loan. Get the right humans to the appointment.

How PostToMarket Automates This

Preapproved buyers fall apart when the listed cash price is wrong, the car status is wrong, or the lead never tells the desk a letter exists. PostToMarket does not fund deals and does not compare lenders. It keeps the vehicle and the conversation visible so the floor can treat the preapproval as information.

The number on the letter has to meet a real price

• Import from CSV or Excel with row-level error logs, so the cash price the buyer matched to their cap is the cash price you still have.
• AI titles and descriptions edited before posting, without leftover "we finance everyone" claims that fight a buyer who already has a lender.
• Inventory statuses plus mark sold and archive, so a pending credit-union deal does not keep generating fresh Marketplace chats.

The desk finds out before the buyer is in the chair

• Leads inbox so a manager can see that the thread mentioned a preapproval.
• Per-rep queues and manager assignment, so the person who booked the visit is the person who should have asked about the letter.
• Team queue view to hand the appointment off if the original rep is gone.

Work the appointment from the lot

• Mobile dashboard to confirm the unit is still available the morning of a credit-union visit.
• Team analytics by source when you want to know which listings attract buyers who already did lender work.

PostToMarket is not affiliated with Meta. It cannot guarantee Marketplace reach or that a preapproval will fund. It reduces the operational mistakes that make a prepared, banked buyer feel like an inconvenience.

Make Outside Financing a Process, Not a Mood

Working with buyers who have a bank or credit union preapproval means treating that letter as work they already did. Read the letter, match it to a real cash price and a real vehicle, explain funding time, and present any dealer option as a choice. Stop driveway contests. Stop pretending the letter does not exist.

If the listing the buyer used to size their cap is still a messy spreadsheet on someone's laptop, you will keep walking into this cold. Starter is $59 per month for a solo seller, one login. Dealership is $299 per month for up to 13 team logins, which is how a manager and an F&I desk see the same lead.
