Buying a home in Washington is exciting, but the inspection period is where you learn more about the property’s condition before closing. This guide explains common home inspection red flags, how seller disclosures can help, and what buyers can do if issues come up while the contract is still active.
A home inspection can help you spot costly problems, ask better follow-up questions, and decide whether to move forward, renegotiate, or bring in a specialist before you finalize the purchase.
While a home inspection isn’t required by law when getting a mortgage loan in Washington State, most mortgage lenders will recommend or require one before signing off on a loan. The inspection is different from the appraisal, which evaluates the value of the home.
While an appraiser looks at some of the same things as a home inspector, their job is making an accurate estimate of the home’s market value. An inspector evaluates the condition of the home and looks for specific problems with the home that might cause it to depreciate suddenly.
Things like brand new appliances, flooring, wall and ceiling paint, and countertops can mask problems below the surface. Before you get too excited about a seemingly freshly remodeled home you just put an offer on, wait for the home inspection report to come back and be reviewed.
The home seller is required by law to fill out a disclosure statement that covers their knowledge of certain things about the home they are selling. These can be a useful starting point, but buyers should still verify important details independently and follow up on anything that is unclear or marked “Don’t know.” Items mentioned on the Washington State home seller disclosure form include:
The source of the property’s water supply must be disclosed, such as where the water comes from (public utility or well) and whether or not the property has an outdoor water sprinkler system.
Material aspects of the property structure should be disclosed, such as the age of the structure, whether the foundation is cracked, and if there have ever been any roof leaks.
If the sewage system for the property is on-site (such as an aerobic or anaerobic septic tank), this should be noted.
If the property is governed by a Homeowners’ Association (HOA) the shared facilities and features (if any) must be listed. These can include fences, walls, gardens, play areas, and the like.
Problems with the property caused by or linked to drainage or flooding problems, or material damage as a result of a fire or earthquake should be listed, along with information about the presence of lead or asbestos.
Disclosures should include specific fixtures and systems such as the hot water tank, electrical systems, plumbing system, HVAC and smoke alarms.
Sellers are also supposed to add information that covers anything that you as the buyer “should know about” that isn’t included in the above list. That is helpful when completed thoroughly, but it should still be treated as one part of your overall due diligence rather than a substitute for an inspection.
It’s better to think of this stage as a search for buyer-verifiable red flags, not assumptions about intent. Here are five issues buyers and inspectors should look at closely, along with why each one matters and when a follow-up may be appropriate.
The age and condition of major items like the water heater, HVAC system, and other built-in components can affect both near-term repair costs and your move-in budget. If the disclosure is vague or the seller says they do not know, ask for documentation, service records, or any available installation dates so you can better understand what may need replacement soon.
A roof does not have to be brand new to be serviceable, but visible wear, missing shingles, patchwork repairs, or signs of past leaking deserve a closer look. Roof issues matter because they can lead to interior damage and bigger expenses later. If the inspection suggests concern, ask whether further review by a roofing professional is warranted.
Water damage can show up around kitchens, bathrooms, laundry areas, windows, and below older flooring. Staining, soft spots, warped materials, or damage near appliances can point to past or ongoing leaks. Because moisture problems can affect subflooring and structural materials, buyers should ask where the leak came from, whether it was repaired, and whether any hidden areas need additional evaluation.
Evidence of carpenter ants, termites, or other pests may not always be obvious during a general walk-through. Pest-related damage matters because it can affect wood framing and other structural components over time. Arrange a separate pest inspection as not all home inspectors know what to look for.
Persistent dampness, musty odors, condensation, staining, or recently covered areas can all be clues that moisture is present where it should not be. Moisture issues matter because they may point to ventilation problems, leaks, or conditions that support mold growth. If the general inspection raises questions, buyers may want to ask about the source of the moisture and whether a more specialized inspection makes sense.
If a seller starts making concessions, like lowering the house price dramatically if you agree to waive a home inspection, consider this a massive red flag. What would they want to miss out on tens of thousands of dollars unless there’s that much (or more) in damage or work to be done on the home?
If they are desperate to close the sale, there might be a reason. Make one of your contingencies related to the right to back out and retain your escrow if the home inspection turns up major problems with the home. If the seller really believes there are no problems, this shouldn’t be a huge ask.
If the inspection report identifies issues, the right response depends on the size of the problem, the cost to address it, and whether it could affect financing or closing timelines. Start by reviewing the report with your real estate agent and separating routine maintenance items from larger health, safety, structural, roof, plumbing, electrical, or moisture-related concerns.
If the issue is clear and the seller can realistically address it before closing, requesting repairs may make sense. If the work is substantial, timing is tight, or you would rather control the repair after move-in, asking for a credit can be a better option. When the inspection points to something beyond a general inspector’s scope, getting specialist bids can help you understand the true cost before you renegotiate.
If the findings materially change the home’s value or the amount of work you are willing to take on, you may decide to renegotiate the purchase price. And if the problems are more serious than expected, walking away under the inspection contingency may be the most practical path where your contract allows it. If any required repairs or property issues could affect the loan, appraisal, or closing timeline, keep your agent and lender informed early so you understand your options.

A home inspection is not required by law when buying a home in Washington, but many buyers choose to get one and many lenders recommend or require it before final loan approval. It helps reveal condition issues that may not be visible during a walk-through.
A home inspection evaluates the condition of the home and looks for problems with systems and structure. An appraisal estimates the property’s market value for the lender. They serve different purposes, even though they may look at some of the same areas.
A deal breaker is usually a problem that materially changes the risk, cost, or livability of the home. Common examples include major structural defects, significant roof problems, serious electrical or plumbing issues, moisture intrusion, or conditions that could affect financing or closing.
Major red flags often include foundation concerns, signs of prior or ongoing roof leaks, water damage, electrical problems, aging HVAC or water-heater systems, pest damage, and persistent damp or mold-supporting conditions. These issues can lead to expensive repairs or hidden damage.
Common problems include roof wear, aging systems and components, water intrusion, plumbing leaks, electrical issues, pest activity, and moisture-related damage. Some items may be routine maintenance, while others may require specialist review or renegotiation.
A general home inspection may not fully evaluate issues that require specialized expertise. If the inspector raises concerns about pests, mold, roofing, or similar conditions, a separate specialist inspection may be appropriate to better understand the scope and cost.
Washington sellers are required to complete a disclosure statement based on their knowledge of the property. Buyers should still verify important details independently, follow up on unclear answers, and use inspections as part of their due diligence.
Washington seller disclosures are expected to cover known material issues with the property, including structural concerns and whether there have been roof leaks. Environmental and drainage-related problems should also be disclosed when known. Buyers should still ask follow-up questions and verify conditions through inspection.
It can make sense when the general inspection points to a specific concern. A separate pest inspection is often useful because not all home inspectors specialize in identifying pest damage. If moisture, mold, drainage, or hidden plumbing issues are suspected, a more specialized inspection may also be warranted.
If the inspection finds major problems, buyers may be able to renegotiate, request repairs, ask for a credit, or walk away under the inspection contingency if the contract allows it. The available options depend on the purchase agreement and the seriousness of the findings.
