Drainage & Water-Flow Audit
This is the Washington checklist. On a lot that drains to the lake, "it was just a wet week" is how buyers talk themselves into a drainage problem.
Inspection and Condition
Direct answer
Washington's slopes and near-lake water table make drainage the most under-appreciated condition issue in town. Watch where water actually goes - during or right after a storm if you can - and you'll spot what the listing photos hid.
Work through the decision in order
Roof & hardscape water
downspout/roof discharge points; driveways/patios pitched toward the house.
Ground evidence
standing water, soggy soil, low spots after rain; splashback staining; erosion channels; basement/crawlspace water lines, sump, dampness.
The slope story
where uphill/neighbor water enters; retaining walls, swales, area drains working; near-lake high water table.
Your next move
Use the framework before the property creates urgency.
Bring the actual address, timing, financing assumptions, and open questions into a buyer strategy call before urgency takes over.
