The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2004.

Read together — 26% mortgage, 51 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$1.2M of Kings, written across 69 government filings.
