1. Using a Generic Template Without State Customization
Why it’s costly: Real‑estate law varies by state. A clause that works in Texas may be illegal in California. Missing state‑specific language can render the entire contract void, forcing you back to the drawing board and paying attorney fees to fix it.
How to avoid it:
- Download a free template that lists “state‑specific add‑ons.”
- Insert the correct jurisdiction clause (e.g., “This Agreement is governed by the laws of the State of Colorado”).
- Run the document through a local real‑estate attorney or use Sellable’s AI‑review tool, which flags missing state requirements for just $29 per review.
2. Omitting Required Property Disclosures
Why it’s costly: Federal law mandates disclosure of known defects, lead‑paint, flood‑zone status, and more. Failure to disclose can trigger lawsuits that recover the buyer’s repair costs plus punitive damages.
How to avoid it:
- Use the official “Seller’s Property Disclosure Statement” for your state.
- Attach it as an exhibit to the purchase agreement.
- Highlight any “known issues” in a separate “Addendum – Material Defects” section.
3. Leaving Purchase Price “To Be Determined”
Why it’s costly: Ambiguous pricing invites last‑minute negotiations, which can erode your profit margin. Buyers may use the uncertainty to push for concessions, and you might end up accepting a lower price just to close.
How to avoid it:
- State the exact price in numbers and words (e.g., “$285,000 (Two Hundred Eighty‑Five Thousand Dollars)”).
- Include a “price adjustment clause” only for agreed‑upon repairs, not vague market fluctuations.
4. Skipping Inspection and Appraisal Contingencies
Why it’s costly: Without a contingency, you’re locked into the sale even if a home inspection uncovers $10,000‑$20,000 of repairs. You’ll either pay out of pocket or risk a breach of contract claim.
How to avoid it:
- Insert a clause: “Buyer may terminate or renegotiate if inspection reveals defects exceeding $5,000.”
- Set a clear deadline (e.g., “Inspection to be completed within 10 business days of acceptance”).
5. Not Setting a Firm Closing Date
Why it’s costly: Open‑ended timelines increase holding costs—mortgage payments, utilities, property taxes—while you wait for the buyer’s financing. Each extra day can cost $50‑$200 depending on your situation.
How to avoid it:
- Specify a closing date (e.g., “Closing shall occur on or before June 30, 2026”).
- Add a “time is of the essence” provision to enforce the deadline.
6. Ignoring Default and Remedy Clauses
Why it’s costly: If the buyer backs out, you may lose the earnest money and incur legal fees. Without a clear remedy, courts can award only a fraction of the loss.
How to avoid it:
- Include a “Default” section that outlines forfeiture of the deposit (typically 2% of the purchase price).
- State the right to retain the deposit and pursue additional damages.
7. Forgetting to Address Personal Property
Why it’s costly: Disputes over appliances, window treatments, or garden tools often surface after closing, leading to small but annoying lawsuits.
How to avoid it:
- List every item included in the sale in an “Included Personal Property” schedule.
- Have the buyer sign an acknowledgment of receipt.
8. Using Vague “As‑Is” Language Without Warranties
Why it’s costly: “As‑is” alone does not shield you from known defects you failed to disclose. Courts may interpret it as a hidden‑defect claim if you had prior knowledge.
How to avoid it:
- Pair “as‑is” with a statement: “Seller makes no warranties except those expressly stated in this Agreement.”
- Attach any existing warranties (e.g., HVAC, roof) as exhibits.
9. Failing to Include Escrow Instructions
Why it’s costly: Without clear escrow directions, the buyer’s lender may send funds to the wrong account, delaying closing and possibly causing the buyer to walk away.
How to avoid it:
- Provide the escrow agent’s name, address, and account number.
- Add a clause: “All funds shall be deposited with [Escrow Agent] within three business days of contract execution.”
10. Overlooking Digital Signature Legality in 2026
Why it’s costly: Some states still require a wet signature for certain disclosures. Using only an electronic signature can invalidate the contract, forcing a re‑signing process that adds $500‑$1,500 in administrative costs.
How to avoid it:
- Verify your state’s e‑signature statutes (e.g., ESIGN Act compliance).
- Use a platform like Sellable that records a time‑stamped audit trail and prompts for a wet signature where required.

- National Association of Realtors (NAR) 2025‑2026 market reports. Provide average attorney fees and typical repair costs.
- Legal journals (e.g., Real Estate Law Review 2026). Offer case studies on default clauses and disclosure lawsuits.

Frequently Asked Questions
1. Where can I download a free FSBO purchase agreement template?
Many county clerk websites and real‑estate blogs offer PDFs. Choose one that explicitly lists “state‑specific add‑ons” and download the most recent 2026 version.
2. Do I need a lawyer to review my free purchase agreement?
Not mandatory, but a 30‑minute attorney review costs $150‑$300 and can prevent $5,000‑$15,000 in later disputes. Sellable’s AI‑review costs $29 and flags the most common omissions.
3. Can I use electronic signatures for a 2026 FSBO contract in California?
California accepts e‑signatures for most contract elements, but the initial property disclosure must be signed wet. Sellable prompts you to print and sign that page if needed.
4. How much earnest money should I ask for in a $300,000 sale?
Typically 2% of the purchase price, or $6,000. Include a default clause that retains this amount if the buyer breaches without a valid contingency.
5. What happens if the buyer’s loan appraisal comes in low?
If you included an appraisal contingency, the buyer can renegotiate or walk away without penalty. Without it, you may have to lower the price or risk a breach claim.
