What Paperwork Do You Need to Sell a House in Washington?

In my experience, home sales rarely stall over price. They stall over paperwork: a payoff statement that takes two weeks to arrive, an HOA resale certificate nobody ordered, a deed still in a late parent's name. Every one of those is avoidable if you gather the documents before the sign goes in the yard. This is the complete list of paperwork you need to sell a house in Washington, organized the way the sale actually unfolds: what to pull together before listing, what gets signed during the sale, what happens at closing, and the special situations that need extra documents. It is written for Vancouver and Clark County sellers, but the Washington rules apply statewide.

Before You List: Gather These First

1. Deed and Title Information

Good news first: you do not need your original deed. Deeds in Washington are recorded with the county auditor, and the title company pulls your full chain of title when escrow opens. What you should do before listing is confirm how the property is actually held. If a co-owner has died, if you have divorced since buying, or if the home sits in a trust or an LLC, those title details need to be sorted before a buyer is waiting on them. Dig out your owner's title insurance policy from when you bought if you can find it; it speeds up the title work.

2. Mortgage Payoff and HELOC Statements

Every loan secured by the house must be paid off through escrow, so make a list: first mortgage, second mortgage, HELOC, and any solar or improvement loan recorded against the property. Pull a recent statement for each. One trap worth flagging: a HELOC with a zero balance is not the same as a closed HELOC. The line itself must be frozen and closed for the lender to release its lien, and that can take time, so start early if you have one.

3. Form 17 Seller Disclosure

Washington law, chapter 64.06 RCW, requires most sellers to give the buyer a completed Seller Disclosure Statement, known as Form 17. You will fill it out with your broker, but the honest answers come from records: repair invoices, inspection reports, service history. Gather those now. Form 17 carries enough legal weight that we wrote a full guide to it; read our Form 17 seller disclosure breakdown before you fill yours out.

4. HOA Documents and the Resale Certificate

If your home is in a homeowners association, plan for two layers of paperwork. First, the basics you likely already have: CC&Rs, current dues statement, and any notice of special assessments. Second, for condos and other common interest communities, Washington law (RCW 64.90.640, with RCW 64.34.425 covering older condominiums) requires the seller to furnish the buyer a resale certificate prepared by the association before conveyance. The association has ten days from your written request to deliver it, it may charge a statutorily capped preparation fee, and the buyer gets a cancellation window after receiving it. Translation: order it the moment you are under contract, or earlier, so the buyer's clock runs early instead of at the finish line.

5. Permits for Improvements

Buyers, appraisers, and inspectors all ask the same question about that finished basement or new deck: was it permitted? Pull records for any significant work from the City of Vancouver or Clark County permit portals before you list. If work was done without permits, tell your broker now. There are ways to handle it, but none of them work well as a surprise during the inspection period.

6. Well and Septic Records

Outside city sewer and water, your documents multiply: well logs, water testing results, septic as-built drawings, and pumping and inspection records. If this is your situation, read our dedicated guide to selling a house with a well and septic in Clark County and start collecting records early; missing septic paperwork is one of the most common closing delays we see in rural Clark County.

7. Solar Lease or Loan Documents

Solar panels come with paperwork that must transfer or be paid off: a lease, a power purchase agreement, or a loan with a UCC filing against the property. The transfer process runs through the solar company and takes time, so locate your contract before listing. Our guide to selling a house with solar panels in Washington walks through each ownership scenario.

8. Warranties and Manuals

Roof certifications, appliance warranties, HVAC service plans, manuals for anything staying with the house. None of these are legally required, but a folder of them backs up your Form 17 answers and signals to buyers that the home has been cared for.

During the Sale: What You Will Sign

Listing Agreement

The first signature of the sale is the listing agreement between you and your brokerage. It sets the list price, the commission, the listing period, and how the home will be marketed. Read it and ask questions. This is a contract, not a formality.

Purchase and Sale Agreement

When an offer arrives, it comes as a purchase and sale agreement on standardized statewide forms; in our market that typically means NWMLS forms, such as the Form 21 Residential Purchase and Sale Agreement, though Clark County brokers work in both major regional MLS systems. The agreement and its attached addenda set the price, earnest money, financing and inspection contingencies, included items, and the closing date. Your broker's job is to translate every contingency into plain English before you sign, because each one is a door the buyer can exit through. For how the offer fits into the larger sequence, see our overview of the steps to sell a house in Washington.

Counteroffers and Addenda

Almost no deal is signed as first written. Counteroffers on price and terms, a financing addendum, an escalation addendum in a competitive market: each is a document you will review and sign, and each modifies the contract. Keep copies of everything; the full signed stack is your deal.

Inspection Response Forms

After the buyer's inspection, expect a written inspection response asking for repairs, a credit, or a price adjustment. Your reply, and any agreement you reach, is documented on response forms that become part of the contract. Keep repair agreements specific and in writing, and save the invoices for closing.

At Closing: The Final Stack

Closing paperwork is mostly prepared for you by the escrow company, but you should know what you are signing. We cover the full timeline in our guide to the closing process when selling a house in Washington; here are the documents that matter most on the seller's side.

• Real estate excise tax affidavit. Washington taxes the seller on the sale under chapter 82.45 RCW, and the affidavit is the form that reports it. Both seller and buyer, or their agents, sign it, and the county treasurer processes it and collects the tax before the deed can be recorded. Escrow prepares it; your job is to review and sign. For current rates and how the graduated tax is calculated, see our Washington real estate excise tax guide.
• Payoff authorization. A signed authorization letting escrow request payoff figures from your lenders and pay them from your proceeds at closing. Sign this early; lender payoff departments are not known for speed.
• The deed. Escrow prepares the deed conveying the home to the buyer, most commonly a statutory warranty deed in a standard Washington sale. You sign it in front of a notary. This is the signature that actually transfers the house.
• Estimated settlement statement. The line by line accounting of your sale: price, payoffs, excise tax, commissions, title and escrow fees, prorated property taxes, and your net proceeds. Check it against your net sheet before signing day.
• Government issued photo ID. The notary must verify your identity, so bring current ID. An expired license has genuinely delayed closings.

Special Situations That Add Documents

• Probate or personal representative sales. Selling a home from an estate requires the court paperwork appointing you, commonly called letters testamentary or letters of administration, and title will review the probate file before insuring the sale. If this is you, start with our guide to selling an inherited house in Washington.
• Power of attorney. If someone will sign for you, the title company must approve the power of attorney document in advance, and it is typically recorded with the sale. Do not wait until signing week to send it over.
• Divorce. Title will want the dissolution decree showing who has authority to sell, and sometimes a quitclaim deed from a former spouse. Getting this reviewed before listing prevents an ugly mid-escrow scramble.
• Out-of-state sellers. You do not need to fly in. Escrow can arrange a mail-out signing or a mobile notary near you; plan a few extra days into the timeline for documents to travel.

The Complete Checklist, In One Place

Here is the whole list, in order. Screenshot it, print it, or forward it to your co-owner.

• Owner's title policy from your purchase (helpful, not required)
• Mortgage, HELOC, and property-secured loan statements
• Form 17 seller disclosure, with supporting repair and service records
• HOA CC&Rs, dues statement, and resale certificate (condos and common interest communities)
• Permits for additions, remodels, and major systems
• Well logs, water tests, septic as-builts, and pumping records (where applicable)
• Solar lease, power purchase agreement, or loan documents (where applicable)
• Warranties, certifications, and manuals for items staying with the home
• Listing agreement
• Purchase and sale agreement, counteroffers, and all addenda
• Inspection response forms and repair invoices
• Real estate excise tax affidavit
• Payoff authorization
• Deed, signed and notarized
• Estimated settlement statement
• Current government issued photo ID
• Special situation documents: letters testamentary, power of attorney, or dissolution decree

The honest secret of a smooth sale is that most of this stack is handled for you when the right people are on it: your broker manages the disclosure and contract documents, escrow manages the closing stack, and you supply the records only you have.

Frequently Asked Questions

What documents do I need before listing my house in Washington?

Before you list, gather your mortgage payoff and HELOC statements, the Form 17 seller disclosure, HOA documents and a resale certificate if the home is in an association, permits for any improvements, well and septic records where they apply, solar lease or loan paperwork, and any warranties or manuals you plan to pass along. Your title company pulls the deed and title history for you, so you do not need the original deed.

Do I need the original deed to sell my house in Washington?

No. Your deed is recorded with the county auditor, so a lost paper copy does not affect your ability to sell. The title company confirms ownership through the recorded chain of title, and escrow prepares a new deed that you sign at closing to convey the home to the buyer.

Do I need a lawyer to prepare the paperwork when selling in Washington?

For a standard sale, no. Washington sellers typically rely on their listing broker for the transaction forms and on an escrow company to prepare the closing documents, including the deed and the excise tax affidavit. An attorney is worth bringing in for special situations such as probate, a contested divorce, or a complicated title issue.

What is the real estate excise tax affidavit and who prepares it?

The real estate excise tax affidavit is the state form that reports your sale under chapter 82.45 RCW so the county treasurer can collect the excise tax before the deed is recorded. Both the seller and the buyer, or their agents, must sign it. In practice your escrow company prepares it and includes it in your closing packet.

How long does it take to get an HOA resale certificate in Washington?

Under RCW 64.90.640, the association must deliver the resale certificate within ten days of your written request and payment of its fee. The buyer then has a five day window to cancel after receiving it, which is why smart sellers order the certificate as soon as they go under contract rather than waiting until closing is near.
