About Us
Modernizing Mass Appraisal
M.A.P.S was built to replace outdated tools with enterprise-grade analytics designed specifically for government assessors.
Our Mission
Mass appraisal is the backbone of fair property taxation. Yet most assessment offices still rely on legacy desktop software, manual spreadsheets, and processes that take weeks to complete.
M.A.P.S — Mass Appraisal & Property Services — exists to change that. We build modern, browser-based tools that bring IAAO ratio-study analytics and transparent valuations to every assessor’s office, regardless of size or budget.
Our clients have seen
- 200–300 analyst hours saved per triennial update
- Months → weeks for a full triennial update
- < 30 s to recompute a full county ratio study
- 35,000+ sales screened and time-adjusted automatically
- 179 neighborhoods analyzed in a single run
Time savings are our appraisal team’s conservative estimate for an Ohio triennial update.

What We Stand For
Accuracy First
Every statistic we compute meets IAAO standards. We never trade accuracy for speed — we deliver both.
Radical Transparency
Assessors need to defend their valuations. Every statistic in M.A.P.S is computed the IAAO way and shown with its method.
Built for Government
We understand public-sector IT: browser-based access, no local installs, and encrypted connections.
