Updated September 2026 with FLYP's current project figures.
The short answer
For most Puget Sound homes built before about 1980, yes, and the sewer scope matters more than the general inspection. Not because a clean report makes buyers bid more, but because it moves the discovery of every expensive problem from day 35 of a live contract, when you have the least leverage, to April, when you still have choices.
The trade is real and you should make it with your eyes open. Once you have the report, you know. In Washington, knowing changes what you have to write on Form 17. A pre-listing inspection buys you time and control, and it costs you the ability to plead ignorance.
Here is how to decide.
What a seller-procured inspection actually covers, and what it does not
A general home inspection is a visual, non-invasive look at the systems a buyer's inspector would look at: roof surface and flashing, attic and insulation, foundation and crawlspace, framing that is visible, plumbing supply and drains at the fixtures, the electrical panel and accessible wiring, heating, water heater, grading and drainage around the house, windows, and the obvious moisture stains that suggest something behind them.
What it does not do is look inside your sewer line. That is a separate service. As The Madrona Group puts it in their rundown of seller-procured inspections in the Seattle area, a general inspection usually does not fully evaluate the inside of the sewer line, and a sewer scope is a separate camera inspection that runs from the house toward the connection point. They also note the practical reason sellers order one: sewer problems discovered late turn into expensive negotiation problems, and buyers who see the information upfront are sometimes comfortable enough to write cleaner terms.
Two other things a general inspection will not settle: anything buried, and anything behind a finished wall. If the report says "recommend further evaluation by a licensed specialist," that is not a finding, it is a question. You can either answer it before listing or hand the question to a buyer's inspector and let their imagination price it.
The findings that actually reprice a Seattle deal
Most inspection items are noise. A missing GFCI, a loose handrail, a slow bathroom fan. Four categories reprice deals, and three of them are Seattle-specific enough that out-of-state sellers get blindsided.
The side sewer
This is the big one. In Seattle, the private side sewer is yours, and it is yours further than most owners assume. Seattle Public Utilities is blunt about it: the entire side sewer, all the way to the connection to the public main, is owned and maintained by the property owner. That includes the run under the planting strip and, in many cases, under the street.
It gets more complicated when the line is shared. SPU explains that from the point that your sewer pipe combines with other properties' pipes, you and your neighbors share maintenance and repair responsibilities. Root intrusion is the classic finding, and SPU is explicit that property owners are responsible for maintaining and repairing their side sewer, including removing roots up to and within the connection to the sewer mainline.
Repair is also permitted work. SPU requires a side sewer permit to construct a side sewer, to make repairs, alterations or additions to one, and to abandon, remove or cap one, and a side sewer permit is valid for 18 months unless you renew it. That matters for timing: this is not a weekend fix you slot in between photos and the first open house.
The roof
Roof age is the item buyers and their lenders both care about, and it is the item that most reliably converts into a credit demand, because a number from a roofer is easy to get and easy to argue.
Drainage and the crawlspace
In our climate, standing water in a crawlspace, a downspout dumping against the foundation, or grading that slopes toward the house reads to a buyer as "future foundation problem," whether or not it is. Drainage findings are often cheap to correct and disproportionately expensive to leave alone, because the buyer's inspector will write it up in the language of structural risk.
Old electrical
Knob and tube, ungrounded two-prong circuits, and certain older panels come up constantly in pre-1950 Seattle housing stock. The complication is not only repair cost. It is that some insurers and some loan products get difficult, which shrinks your buyer pool before price is even discussed.
Repair, credit, or disclose
Every finding lands in one of three buckets. The right bucket depends on how well a buyer can price the item on their own.
| Choice | Best for | Effect on your net | Effect on your buyer pool |
|---|---|---|---|
| Repair before listing | Safety items, drainage, roof, anything a lender or insurer will flag | Costs cash now, protects the price and removes the renegotiation lever | Widest. Financed buyers stay in |
| Credit at closing | Cosmetic or clearly bounded items with a real bid attached | Usually costs more than the repair, because buyers pad the estimate | Neutral, but invites a second round of negotiation |
| Disclose and price it in | Big, uncertain, specialist-scope items you cannot finish before listing | Buyers discount it, often heavily, for the uncertainty | Narrower. Some buyers walk at the word "sewer" |
The pattern worth internalizing: buyers discount uncertainty at a much worse rate than they discount a known, bid, finished repair. A disclosed sewer line "with root intrusion noted, further evaluation recommended" gets priced as a catastrophe. A disclosed sewer line "repaired under SPU permit, invoice and permit record attached" gets priced as a solved problem, and sometimes as a selling point.
The disclosure trade-off: once you know, you have to say so
Washington's seller disclosure statement, Form 17, is built on an actual knowledge standard. The statute directs the seller to make disclosures of existing material facts or material defects based on the seller's actual knowledge of the property at the time seller completes this disclosure statement. Reading an inspection report converts a suspicion into actual knowledge. You cannot un-know it, and you should not try.
It also does not end at delivery. Under RCW 64.06.040, if the seller learns the disclosure statement is inaccurate after delivering it, the seller must amend, and unless corrective action is completed before closing, the buyer can accept the amendment or rescind within three business days. The same three-business-day rescission right attaches to the original delivery under RCW 64.06.020. So the practical question is never "can I avoid disclosing," it is "do I want to disclose a problem or a receipt."
This is the part of the decision where a real estate attorney earns their fee, and a short call with one before you order the inspection is cheap insurance. Nothing in this post is legal advice.
What is usually worth fixing first
If you are triaging with a limited budget, the ranking that holds up across most older Seattle and Eastside homes looks like this:
- Anything that threatens financing or insurability. Old electrical, an unpermitted or failed side sewer, active roof leaks.
- Anything that reads as water. Drainage, downspouts, crawlspace vapor barrier, gutter tie-ins.
- Roof age, if the remaining life is short enough that a buyer's inspector will call it out.
- Everything cosmetic, which is a marketing decision, not an inspection decision.
Items better left disclosed rather than repaired: anything requiring a specialist scope you cannot complete before listing, anything where two contractors give you wildly different diagnoses, and anything a buyer will want to redo to their own taste anyway.
When the pre-listing inspection is the wrong move
It is the wrong move if you have already decided to sell without touching anything and you want the shortest path out. A verified problem you cannot afford to fix is a disclosed problem plus a repair bid, and that combination can cost you more than the buyer's own inspection would have. In that case, look at an as-is sale and price accordingly.
It is also the wrong move if the report will simply paralyze you. A list of forty items is only useful if someone converts it into a scope with prices.
Funding what the report turns up
The usual bind is that April is when you find the problems and April is also when your cash is committed to moving costs. That is the gap a pay-at-closing renovation closes: FLYP plans, funds, and manages the work, the renovation is performed by Green State Restoration, LLC, a licensed and insured Washington general contractor, and you pay from the sale proceeds at closing. Nothing upfront and nothing during the work.
The terms in plain language, because you should never take a number like this on vibes. You repay the fixed contract price on the signed estimate, plus Washington sales tax, plus any change orders you signed, plus the county recording fee. There is no interest during the renovation and none for six months after the work is finished. After that, the balance accrues 1.5% per month, and paying early stops it. Ten months after completion the balance is due directly, whether or not the home has sold. The balance is secured by a deed of trust recorded against the property, signed before an independent notary before work starts, and released within ten business days of payoff. The full walkthrough lives at how the process works.
And the honest part: you can lose money or equity. Markets move, a home can sell for less than projected, and interest can accrue. FLYP will not take a project unless it clears a minimum 1.30x coverage ratio, which means projected net proceeds, the projected after-renovation value less selling costs and less the balance of every senior lien, divided by the maximum amount that could ever become payable to FLYP. That is an underwriting safety margin, not a return and not a promise about your sale.
What the projections actually look like: across the 12 homes that had a projected after-renovation value in FLYP's underwriting files as of September 2026, out of 16 homes underwritten in total, the projected lift over as-is value had a median of 27% and a range of 1% to 89%, and the projected dollars added had a median of $190,000 and a range of $10,000 to $500,000. Those are projections made during underwriting, from a small sample, and several files projected almost no lift at all. No FLYP home has sold yet, so there are no sale figures of any kind.
The bottom line
Order the sewer scope. On an older Puget Sound home it is the cheapest way to find the one item that can blow up a live contract, and a repaired, permitted line prices far better than a disclosed unknown. Order the general inspection too, but only if you intend to act on it, because reading it puts the findings inside your Form 17 actual knowledge. Sort every finding into repair, credit or disclose before a buyer's inspector sorts it for you.
