King County Foreclosure - Owners can buy back after 1 year?

[Nic Werner]

A property developer told me they avoid foreclosures because the owners could come back within a year and re-claim their property. Is this true? I've been doing research, but can't find anything about this. The King County Foreclosure office wouldn't answer me and told me to speak with a lawyer.

This doesn't seem correct - that I'd buy a property, fix it up, and then the owners can take it back from me just by paying their back taxes.
