How to Screen Buyers FSBO: Red Flags Sellers Should Catch Early
$12,800 is the average amount FSBO sellers lose when they accept a buyer who later backs out after a contract is signed. Spotting red flags before you sign saves that money and keeps your timeline on track.
Direct answer: What does “screening buyers” mean for a FSBO seller?
Screening buyers means verifying a prospect’s financial ability, motivation, and reliability before you sign a purchase agreement. You do it by requesting proof of funds, checking pre‑approval status, confirming identity, and watching for behavior that signals risk.
1. Verify financial muscle right away
| Proof required | Typical amount | How to verify | Red flag |
|---|---|---|---|
| Bank statement or proof‑of‑funds letter | $50,000–$250,000 (or 20 % of your asking price) | Call the issuing bank’s verification line; ask for a signed, dated statement on official letterhead | Screenshot of a “bank app” with blurred numbers |
| Mortgage pre‑approval | Loan amount covering at least 80 % of price | Contact the lender to confirm pre‑approval is current (within 30 days) | Pre‑approval dated more than 60 days ago |
| Earnest‑money deposit | 1–3 % of price, usually $2,000–$7,500 | Request a certified check or wire receipt before the inspection period | Deposit offered as “cash on delivery” or “gift card” |
Action step: Ask for the document, note the date, and call the source. If the seller can’t produce a verifiable statement, walk away.
2. Confirm buyer identity and contact reliability
Direct answer: Ask for a government‑issued ID and a recent utility bill, then run a quick reverse‑lookup on the phone number.
- Request a driver’s license or passport.
- Match the address on the ID with a recent utility bill (within 30 days).
- Run the phone number through a free reverse‑lookup tool (e.g., TrueCaller) to see if it’s linked to a business or a known spam source.
Red flags:
- ID that looks scanned or edited.
- Utility bill dated more than 90 days ago.
- Phone number that shows up as a call‑center or “unknown” in multiple listings.
3. Test buyer motivation and timeline
Direct answer: Ask three concrete questions: when they need to move in, how they’ll fund the purchase, and whether they have a current home to sell.
| Question | Desired answer | Warning sign |
|---|---|---|
| “When do you need to close?” | 30–45 days, or a date you can accommodate | “Whenever you’re ready” without a clear timeline |
| “Are you selling another property first?” | Yes, with a confirmed contract, or No, with cash/loan ready | “I’m still looking for a place to rent” |
| “What’s your biggest concern about this purchase?” | Financing or inspection details | “I just want a good price” without specifics |
If the buyer can’t give precise dates or shows vague concerns, they’re likely to stall or bail.
4. Spot buyer‑agent collusion
Direct answer: Even though you’re FSBO, many buyers bring an agent who may push for a lowball offer or request excessive repairs.
- Ask who represents the buyer. If the buyer says “I’m working with an agent,” request the agent’s license number and contact the state real‑estate commission to confirm they’re active.
- Check the communication pattern. An agent will often send “standard” forms that contain clauses favoring the buyer, such as “seller pays all closing costs.”
Red flag: The buyer refuses to disclose their agent or provides a non‑licensed “consultant.”
5. Use a short, binding offer form
Direct answer: Provide a one‑page “Buyer Intent Form” that requires signatures, dates, and the same proof‑of‑funds you demand later. This creates a paper trail and deters unserious parties.
- Include a clause that the buyer forfeits the earnest‑money deposit if they withdraw after the inspection period without cause.
- Have both parties sign in front of a notary or use Sellable’s e‑signature platform for verification.
Red flag: The buyer balks at signing any document before seeing the house.
Quick screening checklist
- Request proof of funds or pre‑approval (verify with source).
- Collect a government ID and recent utility bill; run a reverse‑lookup.
- Ask three timeline questions; note vague answers.
- Identify any buyer’s agent; verify license.
- Have the buyer sign a binding intent form with earnest‑money terms.
If any step raises a red flag, pause the negotiation and consider another buyer.

Frequently Asked Questions
What is a reasonable earnest‑money deposit for a $250,000 FSBO sale?
Typically 1–3 % of the price, so $2,500–$7,500. It should be a certified check or wire, not cash.
Can I accept a buyer who only has a verbal pre‑approval?
No. Verbal pre‑approvals lack documentation and can be withdrawn. Request a written, dated pre‑approval letter from the lender.
How do I handle a buyer who insists on a “contingency‑free” offer?
Ask for proof of cash or a fully funded loan. If they can’t provide it, the contingency‑free claim is likely a negotiation tactic.
What should I do if a buyer’s agent asks for a “seller‑pay‑all‑closing‑costs” clause?
Negotiate the clause or remove it. An FSBO seller can split costs, but paying everything erodes your profit margin.
Is it safe to use electronic signatures for the intent form?
Yes. Sellable’s e‑signature feature complies with the ESIGN Act and provides a timestamped audit trail.
