Big-lot fixer, four minutes from Columbia City Station

Original 1918 cottage on a deep 6,000 sqft lot. It needs updating throughout — but the land is the story: two neighboring owners on the block are long-time holders too, and the site sits inside the light rail walkshed.

Disclosure risks

Risk score

100/100

What we flagged in the seller disclosure and public records, with typical repair costs, before you pay for an inspection.

Roof is ~27 years old
High risk
Past typical composition-roof life. Expect to replace it soon.
$16K–$28K
typical cost
Likely knob-and-tube wiring
High risk
Common before 1940. Many insurers require replacement before they will bind a policy.
$12K–$28K

Oil heat — possible buried tank
Medium risk
Ask for decommissioning records and order a tank sweep. Converting to a heat pump qualifies for rebates.
$3K–$8K

Original clay side sewer
Medium risk
Typical for pre-1970 homes. A $350 sewer scope shows whether roots have gotten in.

House isn't bolted to its foundation
Medium risk
A seismic retrofit is an affordable, high-value upgrade in Seattle and can lower earthquake premiums.
