The problem
Producing an appraisal report still takes hours — across disconnected tools.
01
Manual sample collection
Hours scraping listings, copying data into spreadsheets and cleaning duplicates by hand.
02
Statistics in desktop software
Regression models in legacy tools locked to a single computer, with no collaboration or history.
03
NBR 14653 classification at risk
Grounding and precision degrees checked by hand — easy to miss an item and compromise the report.
04
Report layout in Word
Assembling calculations, tables, charts and appendices by hand, from scratch, every time.
How it works
From property to PDF, in three steps.
01
Automated market research
Enter the region and property type. Valora collects listings, cleans, deduplicates and enriches samples with IBGE income and location — no spreadsheet.
02
AI-assisted modeling
Multiple linear regression with assisted variable selection, transformations, diagnostics and automatic degree classification per NBR 14653-2. The appraiser decides; AI prepares the way.
03
Report ready in PDF and Word
Calculation memorials, charts, maps and appendices generated automatically, with grounding and precision degrees — editable and ABNT-compliant.
Valuation engineering + AI
Three levers that cut report time by 80%.
AI-assisted inference
Guided selection of explanatory variables, multiple-regression fitting and assumption checks. The appraiser decides — AI paves the way.

FAQ
Questions from appraisers.
Is Valora an alternative to desktop appraisal software?
Yes. It's a modern, cloud-based platform unifying market research, statistical modeling and report generation — without a desktop tool locked to one computer. You keep full control of technical decisions.
Is the report NBR 14653-compliant?
Yes. The engine automatically classifies grounding and precision degrees per NBR 14653-2 tables, and the report is generated in PDF/Word with memorials, charts and appendices per ABNT.
Does AI replace the appraiser?
No. AI speeds up repetitive steps (collection, variable suggestion, model interpretation, fill-in), but all technical decisions and responsibility remain with the qualified professional.
Which appraisal methods are supported?
Direct market data comparison (regression), evolutionary (Ross-Heidecke), involutive and income capitalization — covering the main NBR 14653 methods.
Do I need to install anything?
No. Valora runs in the browser. You can start by trying the free tools — like IBGE income lookup and the grounding-degree calculator — with no install.
