The market offers different solutions for preparing PTAMs. Here are the main options and their characteristics.
1 · Traditional spreadsheets and documents (Excel / Word)
The most basic approach. Fully customizable and with no subscription cost, but it means building the calculations by hand — laborious, error-prone, hard for organizing photos and maps, and with no automatic updates to standards.
2 · SINAPI Online
The official cost database from Caixa Econômica Federal, updated periodically. Focused on the evolutive method (reproduction cost) — without features for preparing the complete PTAM.
3 · Valor360
A digital platform specialized in preparing PTAMs in line with ABNT NBR 14653, built for real estate agents and appraisers.
How to choose the right tool
- Compliance with technical standards — does it follow ABNT guidelines?
- Ease of use — is it intuitive and does it cut preparation time?
- Quality of the final report — does the generated PDF look professional?
- Value for money — is the cost in line with your workload?
- Technical support — is help available when questions arise?
- Updates — does the platform keep up with changes to the standards?
Choosing the right tool can be the difference between a PTAM prepared in hours versus days — with superior technical quality and a professional presentation that elevates the appraiser's work.
