The Washington State Real Estate Contract: What Buyers Routinely Miss Before They Sign

Washington State uses a standardized purchase and sale agreement - Form 21 - for most residential transactions. Most buyers have signed one. Most buyers, if asked afterward, couldn't tell you what the key sections actually do.

That's not a criticism. The form is long, the language is dense, and no one on the sales side has a particular incentive to slow down and walk through it.

Here are the sections that matter most, what they actually do, and the places buyers consistently misunderstand them.

1. Earnest Money - When It's at Risk and When It Isn't

Earnest money is a deposit that signals good faith. The amount is negotiable but typically runs 1–3% of the purchase price in South King County. The critical question isn't how much it is - it's under what conditions you can get it back.

The short answer: your earnest money is protected as long as your contingencies are active and you use them properly. It becomes at risk when you waive contingencies, let deadlines pass without acting, or make a decision to walk away that isn't covered by a remaining contingency.

Where buyers make mistakes: assuming the earnest money is always refundable, or not understanding that failing to respond within a contingency deadline can be treated as a waiver. Your timeline in this contract is not advisory - it's binding.

2. The Inspection Contingency - What You're Actually Getting

The inspection contingency gives you the right to have the home professionally inspected and, depending on the outcome, to negotiate repairs, request credits, or exit the contract. But the form doesn't automatically guarantee all three options - the specific language in your offer shapes what you can do.

There are two main structures you'll see:

• Inspection contingency with a right to rescind: You can exit for any reason during the inspection period and recover your earnest money. This is the strongest buyer protection.
• Inspection contingency tied to specific defects: The contract may limit your exit rights to certain categories of problems. Less protective.

What most buyers don't know: in competitive markets, some buyers waive the inspection contingency entirely to strengthen their offer. That eliminates your exit right if something significant is found after closing. We never recommend waiving it without a clear-eyed conversation about the risk - and sometimes there are alternatives, like a pre-inspection before making an offer, that accomplish the same competitive goal without the same exposure.

3. Financing Contingency - Read the Date, Not Just the Clause

The financing contingency protects you if you can't secure a loan. But it has a deadline - typically tied to the closing date - and if you miss it without requesting an extension, the protection weakens or disappears.

The practical implication: if your lender encounters a delay (appraisal issues, underwriting conditions, anything), you need to communicate that with your agent immediately. Letting the financing deadline quietly pass while assuming everything is fine is one of the more common ways buyers end up with earnest money at risk.

Also worth knowing: the financing contingency covers you if you can't obtain a loan. It doesn't cover you if you change your mind about buying. Those are legally different situations.

4. Seller Disclosure - What Sellers Are Required to Tell You

Washington is a disclosure state. Sellers are required to disclose known material defects using a standardized Seller Disclosure Statement (Form 17). This covers the physical condition of the 

home, any legal or financial encumbrances, and various system-specific questions (roof, plumbing, electrical, etc.).

Two things to understand about seller disclosure:

• Sellers disclose what they know. They're not required to have the home inspected before selling, and they can't disclose what they're genuinely unaware of. Seller disclosure is a starting point, not a substitute for an inspection.
• The "as-is" designation doesn't eliminate disclosure requirements. Sellers in Washington still have to complete Form 17 even if they're listing the home as-is. "As-is" means they're not agreeing to make repairs - it doesn't mean they can withhold known material facts.

5. The Closing Date - More Flexible Than It Appears

Closing dates are negotiated, not fixed. The date in the contract is a target, and both parties can agree to extend it. What most buyers don't realize: extensions require mutual agreement in writing. One party can't unilaterally push the closing without the other's consent.

Where this creates problems: buyers who assume their lender's delays are automatically accommodated, or sellers who've already lined up moving plans around a specific date. The closer you get to the stated closing date, the more important it is to have real-time communication between both sides.

A Note on What We Do With This

When we put an offer together, we walk through each of these sections specifically - not generally. We don't hand you a contract and say 'let us know if you have questions.' We go through the dates, the contingency structures, the earnest money exposure, and what each clause means for your specific situation.

If there's something in a contract you don't fully understand before you sign it, that's what we're here for. Understanding what you're signing isn't a bonus - it's the foundation of a transaction you can feel confident about.
