Most sellers think of the home inspection as something that happens to them — a report a buyer orders after they're already under contract, one that can blow up a deal or force a last-minute credit negotiation. But there's a version of the inspection where you're the one holding the report before a single buyer ever walks through the door. With Eastside inventory up and buyers taking their time to compare options this fall, that head start is worth more than it used to be.

Here's what a pre-listing inspection actually costs, what it tends to turn up on Eastside homes, and how to use the report once you have it.

Why this matters more this fall than it did a year or two ago

King County currently has around 4.2 months of active inventory — the most buyer choice since the market shifted in 2020 — and homes are averaging roughly 24 days on market before going pending. That's a real shift from the multiple-offer years, and it means buyers can afford to be selective. A listing with a surprise in escrow doesn't just cost you the repair — it costs you the momentum of being new on the market, and Eastside buyers this fall have other options to go look at instead of waiting on you to sort it out.

A pre-listing inspection doesn't eliminate the buyer's own inspection — they'll still order one, and they should. What it does is make sure you're not finding out about a failed side sewer or a dying furnace at the same time your buyer's inspector is.

What it actually costs on the Eastside

Pricing scales with the size and age of the home, and Eastside costs tend to run above the statewide average because of larger square footage and older housing stock:

Condos and townhomes (under 1,500 sq ft): $350–$500
Small homes (1,500–2,200 sq ft): $450–$600
Mid-size homes (2,200–3,200 sq ft): $550–$700
Larger homes (3,200–4,500 sq ft): $650–$850
Luxury homes (4,500+ sq ft): $800–$1,100+

For comparison, the statewide average for a standard single-family home runs closer to $550–$750, and one broader Washington-wide estimate puts a basic pre-listing inspection as low as $296–$424 — the range really does depend on home size, age, and which add-ons you include. Speaking of add-ons, these are the ones worth knowing about:

Sewer scope: $275–$325
Radon test: $100–$200
Mold screening: $150–$300
Infrared scan: $300–$500
Oil tank sweep: $200–$400

The one add-on worth prioritizing

If you only add one thing to a standard inspection, make it the sewer scope. For any home east of I-405 that's over 25 years old — especially with mature trees nearby — a $275–$325 camera run down the line is, in the words of one local inspection team, "the single best $300 a seller can spend." Cast iron and Orangeburg pipe from before 1980 fail from root intrusion often enough that it's one of the most common surprises in Eastside escrow, and replacement runs $12,000–$25,000 in Bellevue. Finding that out before you list means you can price around it, negotiate a repair in advance, or budget the fix — not scramble for it during a 10-day contingency period.

What else inspectors are actually finding on Eastside homes right now

Beyond the sewer line, a few issues show up again and again on homes built between 1985 and 2005: aging roofing systems, polybutylene or galvanized supply lines, furnaces in the 80% AFUE range nearing the end of their service life, single-pane windows with broken seals, missing GFCI outlets, deck flashing failures, and compromised vapor barriers in crawl spaces. None of these are unusual for a home of that age — they're just easier to deal with on your terms than a buyer's.

Two other patterns worth watching for:

Drainage and grading on hillside lots — common across Kirkland, Bellevue, and parts of Sammamish — where negative grading toward the foundation can trigger a soils engineer review running $3,000–$8,000 if a buyer's inspector flags it first.

Outdated electrical — Federal Pacific panels, knob-and-tube wiring, or aluminum branch circuits — which increasingly complicates both insurance coverage and buyer financing, and is far easier to address calmly before listing than during a financing deadline.

None of this means your home has a problem. It means homes of a certain age in this area tend to share a few predictable issues, and finding out which ones apply to yours is cheaper before you're under contract than after.

The part sellers don't always think through: Form 17

Washington requires sellers to complete a Seller Disclosure Statement — Form 17 — under RCW 64.06, answering "Yes," "No," or "Don't Know" to a long list of questions about the property's condition. The key word in that form is known. Form 17 asks what you know, not what a professional would find — it's a disclosure of your awareness, not an expert evaluation.

That's exactly why a pre-listing inspection changes your position. Once an inspector tells you about an issue, you know about it, and Form 17 asks you to disclose what you know. Some sellers hesitate here, worried that ordering an inspection just creates more to disclose. In practice, it's the opposite protection: disclosing a known issue up front, priced or repaired accordingly, is a manageable conversation. Having a buyer discover the same issue after closing — and arguing you should have known — is a legal exposure you don't want, and Washington's disclosure law gives buyers real grounds to pursue it. Buyers will still do their own inspection regardless of what you disclose; a pre-listing report just means your Form 17 answers are accurate instead of technically true but incomplete.

Three ways to use the report once you have it

Once you're holding a pre-listing inspection report, you generally have three paths for each item it flags:

Fix it before listing. Best for anything relatively affordable and highly visible — a roof repair, a GFCI swap, a failed sewer line — where showing up to the market already resolved is worth more than the repair cost.

Credit for it. For bigger-ticket items you'd rather not manage yourself — an aging furnace, an electrical panel upgrade — disclose the issue with a repair estimate attached and let buyers factor it into their offer instead of negotiating blind in escrow.

Disclose and price around it. For homes where several items add up, or where a full renovation doesn't make sense before selling, price the home honestly for its actual condition. Buyers respond better to a fairly priced home with known issues than a fully-priced home where they're worried about what they haven't found yet.

Bottom line

A pre-listing inspection costs a few hundred dollars and a short window before you go live. What it buys you is control: no surprise mid-escrow credit negotiation, an accurate Form 17, and a listing that can honestly say it's been vetted — which matters to buyers who have other Eastside homes to compare yours against this fall. On a home in the $1M-plus range, a $500–$900 inspection that catches one real issue before a buyer's inspector does routinely pays for itself several times over.
