25 Things to Check Before Making an Offer on a Home in the Greater Seattle Area

Every buyer I work with reaches the same moment eventually. They walk into a home, and something inside them says, this could be it. The light is right. The layout makes sense. They can already picture their furniture in the living room and their morning coffee on the back deck.

That feeling matters, and it should never be dismissed. However, that feeling is also exactly the moment when a buyer needs a steady, experienced voice beside them, because falling in love with a home too quickly is how buyers miss the details that matter most.

I have walked hundreds of buyers through this exact moment across Bothell, Edmonds, Mill Creek, Woodinville, and every corner of King and Snohomish County. What I have learned is that the buyers who feel most confident on closing day are the ones who slowed down just enough to look past the emotion and into the details, without ever losing the excitement of finding their home.

This is the checklist I walk through with my own clients before we write an offer. Save it. Share it with a friend who is house hunting. Use it as your own guide the next time you walk through a home that makes your heart skip a beat.

Before You Even Schedule the Showing

1. Confirm the school district, not just the city. School district boundaries do not always match city limits in our region, and a home two streets away can fall into a completely different district.

2. Look at the actual commute at the actual time you would drive it. A commute that looks reasonable on a map can feel very different at 8am on a Wednesday. Drive it yourself if you can, at the time you would actually be driving it.

3. Research the property's price history. Has it been listed before? Did the price drop? A little history often tells a story worth understanding before you fall in love with the listing photos.

4. Check the days on market. A home that has sat for a while may have more room for negotiation, or it may signal something the market has already noticed.

5. Review recent comparable sales in the immediate neighborhood. This gives you a realistic sense of whether the asking price reflects the current market, rather than a hopeful one.

During the Showing

6. Look up, not just around. Water stains on the ceiling, sagging areas, or discoloration can point to roof or plumbing issues worth investigating further.

7. Check the water pressure in more than one faucet. Weak pressure throughout the home can point to plumbing issues that are worth understanding before you write an offer.

8. Open every window and door you can. Sticking windows, doors that do not latch properly, or frames that look uneven can be signs of settling or moisture damage.

9. Look for signs of water intrusion in the basement or crawl space. Musty smells, discoloration, or visible dampness are worth noting and worth asking about directly.

10. Test the electrical panel and outlets. An older panel may need updating, which is an important cost to understand before you commit.

11. Check the age of the roof. Ask the listing agent directly, and factor the answer into both your offer and your insurance conversation.

12. Check the age and condition of the furnace and water heater. These are two of the more expensive systems in a home to replace, and knowing their age helps you plan ahead.

13. Walk the yard and check the grading around the foundation. Water should slope away from the home, not toward it. Poor grading is a fixable issue, and it is also one worth knowing about before closing.

14. Look closely at the driveway, walkways, and any retaining walls. Cracks, heaving, or shifting can point to larger drainage or soil issues nearby.

15. Check cell phone signal and internet availability at the property. In some of our more wooded or hillside neighborhoods, connectivity can vary more than buyers expect.

16. Note noise levels at different times, if possible. A quiet street at 10am can feel very different during rush hour or on a weekend.

17. Ask about neighboring properties and any pending development nearby. A quiet field today could be new construction in two years, and it is worth understanding what is planned nearby.

Before You Write the Offer

18. Get a real insurance quote for the specific property. As I always tell my buyers, a generic estimate is not the same as an actual quote, and this step can reveal costs worth knowing before you are under contract.

19. Review the property tax history, not just the current bill. Understanding how the tax bill has changed over recent years gives you a much more realistic monthly budget.

20. If the home has an HOA, request and review the full HOA documents. Look closely at monthly dues, reserve funds, and any record of past or upcoming special assessments.

21. Ask your lender for an updated, specific monthly payment estimate for this exact property. A preapproval letter shows what you qualify for, and a property specific estimate shows what this particular home will actually cost you each month.

22. Confirm what is included in the sale. Appliances, window coverings, and fixtures should always be spelled out clearly, and confirming this in writing prevents confusion later.

23. Ask about the sellers' reason for moving and their timeline. This context can shape your negotiation strategy and help you write an offer that genuinely works for both sides.

24. Understand current market conditions for that specific neighborhood and price point. A home in Mukilteo may be moving quickly while a similar home in another area is sitting. Local, current knowledge changes your strategy.

25. Build your offer with your Realtor's full guidance, not just the number. The strongest offers are rarely just about price. They are about terms, timing, contingencies, and how the offer is presented and communicated to the seller's agent.

Why This List Matters More Than Ever in Today's Market

Our market has shifted meaningfully over the past year. Inventory across King and Snohomish County has increased, and buyers finally have more room to compare, to ask thoughtful questions, and to make a decision from a place of confidence rather than urgency. That is genuinely good news.

However, more choices also mean more responsibility falls on the buyer to evaluate each home carefully rather than rushing simply because a home is available. The buyers who move through this checklist thoughtfully are the ones who write offers with real confidence, and confidence is what leads to smoother transactions and fewer surprises after closing.

I have also seen the opposite play out. A family falls in love with a home, skips a few of these steps in the excitement of the moment, and finds themselves managing an unexpected repair or an underestimated monthly cost a few months later. None of that is necessary. A thoughtful process protects the excitement of buying a home rather than taking away from it.

The strongest offers are built long before the paperwork is drafted. They are built through preparation, through asking the right questions at the right moment, and through having someone in your corner who has walked this exact path with hundreds of families before you. My role is never to slow down your excitement. It is to make sure that excitement is matched by real confidence in the decision you are making.

Frequently Asked Questions

What should I check before making an offer on a house?

Before making an offer, buyers should confirm the school district, review recent comparable sales, get a specific insurance quote, understand the property tax history, check the age of major systems like the roof and furnace, and review any HOA documents closely. Working with a local Realtor ensures none of these steps are missed.

What are common red flags when buying a house?

Common red flags include water stains on ceilings, musty smells in basements or crawl spaces, poor grading around the foundation, sticking doors or windows, and cracks in driveways or retaining walls. None of these automatically disqualify a home, and they are worth investigating fully before writing an offer.

How do I know if a home is priced fairly before I offer?

Reviewing recent comparable sales in the immediate neighborhood, along with the home's own price and listing history, gives you the clearest picture. A local agent who tracks these numbers daily can tell you quickly whether a listing is priced in line with the current market.

What paperwork should I review before writing an offer?

Buyers should review HOA documents if applicable, the property's tax history, and a specific insurance quote for that property. Your Realtor and lender can help gather all of this quickly so you can move forward with clarity.

Do I need to check the school district before making an offer?

Yes, especially in our region, where district boundaries do not always follow city lines. Confirming the exact district a property falls into, rather than assuming based on the city name, is an important step for any family with children or future plans for a family.

What should I look for during a home showing?

Beyond the layout and finishes, buyers should look up at ceilings for water stains, test water pressure, open windows and doors, walk the yard and check grading, and ask about the age of major systems. A thorough showing protects your excitement rather than taking away from it.
