Stress-test a caller-supplied property price or assessment notice for one US address again
Stress-test a caller-supplied property price or assessment notice for one US address against cited recorded-sales, parcel, permit, hazard, tax, zoning, legislation, and same-roll assessment-uniformity evidence in protest mode; Locus never creates or endorses a price, ARV, deal judgment, or investment score, and the result is charge-free if under two substantive sections resolve. npx @velinussage/locus-agent-skill add.
