Reality Gap · Fair Price Score

What the papers say vs what you actually inherit

The Fair Price Score (formerly Reality Gap Score) quantifies divergence between the legal records and the likely physical reality. Under Simplex 2024, those divergences become your liability at the Escritura Pública.

Upload documents

Certidão Permanente, Caderneta Predial Urbana, and Licença de Utilização (plus plans where relevant).

Get a 0–10 score

The score reveals how likely the legal and physical realities diverge.

Negotiate before signing

If the Fair Price Score is high, act early: investigate and renegotiate before liability transfers.

Your protection window: before the CPCV and before the Escritura Pública.

HomeOS measures the paperwork gap on a 0–10 scale: Fair Price Score.
