What AppraisersTech Is
AppraisersTech is a developing appraisal workflow platform created by a practicing appraiser. It is designed around a very specific problem: appraisers often do strong analysis, but lose time retyping, reorganizing, and rebuilding the same market support over and over.
The current direction centers on a paired sales database workflow. You paste in comparable sales, identify likely paired sales, enrich those records with tax and location data, and build a growing database of reusable support. From there, relevant support can be selected for the assignment and pushed into a reporting workflow that works alongside tools appraisers already use.
Strong appraisal work already exists. It just does not scale.
How Appraisers Actually Work
Most appraisal software is built around filling out a report. But that’s not how real appraisal work happens.
The real work happens before the report is ever written—when the appraiser is digging through comparable sales, analyzing differences, and trying to determine how the market actually reacted to those differences at the time of the effective date.
In a typical assignment, I start by pulling tax data, setting up the file in TOTAL, and loading maps and subject information. Then I move into the core of the process: searching for comparable sales.
This is where the real analysis begins. Comparable sales are filtered by location, size, and timing, but that’s only the starting point. From there, the goal is to understand how specific features—condition, garage count, location influences, or other characteristics— actually impacted sale prices in the market.
Instead of relying on broad assumptions, I use paired sales analysis to isolate these differences. This often means going back through prior years of sales to find properties that sold more than once or that closely match except for a single feature.
That level of analysis is not quick. A single paired sales conclusion can take hours to properly identify, verify, and support. Because of that, most appraisers do not consistently work at this level. Not because they cannot—but because the process is time-consuming, mentally taxing, and difficult to scale within the constraints of typical assignments.
This process turns the assignment into a problem-solving exercise. Each difference is tested against the market until the adjustments begin to align in a way that reflects real buyer behavior.
In practice, this is where the gap forms between typical reports and truly well-supported reports. The analysis exists—but the effort required to consistently perform and document it prevents it from being used to its full potential.
Where the Process Breaks Down
Once the analysis is complete, most appraisers still have to stop and rebuild the report manually.
Even after solving the valuation problem, there is a second step where everything has to be re-typed—adjustments, explanations, and supporting logic. This isn’t just time-consuming; it requires mentally retracing the entire process to summarize how the conclusion was reached.
That disconnect is where time is lost and where errors can be introduced. The thinking and the reporting are treated as two separate tasks, even though they are really part of the same process.
A Different Approach
My approach is built around eliminating that disconnect.
Instead of solving the problem first and writing the report after, the goal is to have the report develop in real time as the analysis is being performed.
Tax data should not need to be retyped. Adjustments should not need to be rewritten. Patterns and inconsistencies should be visible immediately, without requiring additional effort to find them.
By combining structured data with tools like Excel and the TOTAL worksheet, it becomes possible to:
- Carry property data directly into the report without re-entry
- Track paired sales and adjustment logic as they are discovered
- Highlight inconsistencies automatically using conditional formatting
- Generate narrative support at the same time adjustments are applied
The result is a workflow where, once the valuation problem is solved, the report is already written—accurately, consistently, and supported by the same logic used to reach the conclusion.
What This Means
Appraisal is not about filling out forms. It is about understanding how the market behaves and supporting that understanding with evidence.
The tools should reflect that.
The goal is simple: eliminate redundant work, reduce opportunities for error, and allow the appraiser to focus entirely on analysis instead of re-typing the same information over and over again.
Not Another Software Platform
AppraisersTech is not being built as another piece of software that forces appraisers into a new system. It is built around a different idea: the workflow is what matters.
Over time, I have rewritten my own process multiple times—refining it across years of real assignments, paired sales research, and report writing. The conclusion was simple: appraisers do not need more platforms, more logins, or more layers.
The core tools already exist. Excel. TOTAL. Data sources. Subscriptions.
After exploring more complex development paths—including building tools with Python, JavaScript, and frameworks like Django—it became clear that adding layers of technology was not the solution.
The core functionality already exists in tools appraisers use every day. Excel can structure, organize, and process data efficiently. TOTAL can handle reporting and narrative through its worksheet system.
The issue was never capability—it was workflow.
The refined approach became much simpler: paste MLS data into Excel, make decisions based on structured analysis, carry that data into TOTAL, apply adjustments, and allow the worksheet to generate the narrative naturally.
Instead of building something entirely new, the focus shifted to improving how these existing tools work together.
AppraisersTech is being built to connect those steps into a single working process instead of forcing the appraiser to manually bridge every gap.
AppraisersTech is focused on solving that problem by building tools that sit within the existing workflow, not on top of it. Tools that carry data forward, reduce re-entry, and allow the report to develop naturally as the analysis is being performed.
This is not about replacing how appraisers work. It is about refining it—based on years of real-world assignments—and removing the friction that slows it down.
The goal is simple: paired sales analysis that would normally take hours becomes reusable, scalable, and integrated directly into the reporting process.
Stronger Support. Fewer Revisions.
When adjustments are fully supported by the market, the conversation changes from questioning the report to understanding it.
One of the biggest advantages of a paired sales–driven workflow is not just speed—it is clarity and support.
When adjustments are derived directly from the market, they do not need to be defended after the fact. The support is already built into the report.
In many reports, adjustments are rounded or generalized—$25,000, $30,000, or other simplified figures. My approach is different. If the market indicates a $61,000 adjustment, that is what is applied.
Those numbers may look unusual at first glance, but they are not arbitrary. They are extracted from specific paired sales and tied directly to observable market behavior.
The report then states exactly where the adjustment came from: paired sales A and B, supported by actual transactions in the market.
It is not uncommon to have multiple adjustments in a report that exceed typical thresholds or percentages. That is acceptable when they are market-extracted, supported, and clearly explained.
As a result, revision requests are reduced. Instead of being asked to justify adjustments after submission, the support is already in place, and the reasoning is transparent.
The focus shifts from defending the report to simply presenting it.
In one assignment, I extracted a paired sales adjustment for a two-bedroom ADU using a comparable property located just over a mile from the subject. Both properties had similar ADU configurations, and the adjustment was supported directly by the market data.
The level of support led to an unusual situation: an underwriter contacted me directly to help explain the adjustment to the investor. In over 20 years of appraisal work, that had never happened before.
The issue was not whether the adjustment was correct—it was that the analysis required a level of familiarity with paired sales that is not always common. The support was there. It simply needed to be translated.
That experience reinforced what paired sales analysis does at its best: it reduces ambiguity, strengthens support, and makes the report easier for others to understand at every level of review.
The Workflow Direction
Start with the sales you are already analyzing for the assignment.
Surface likely market-support relationships without rebuilding everything manually.
Pull tax and location data so the database becomes more useful over time.
Build a growing paired sales database that becomes more valuable with every assignment.
Use the paired sales you select alongside Excel and TOTAL-based processes instead of fighting them.
Let the worksheet structure do more of the lifting so the appraiser can stay focused on analysis.
Paired Sales First
Built around defensible market support instead of generic automation for automation’s sake.
Less Typing
The philosophy is fewer repetitive steps, fewer unnecessary buttons, and less manual re-entry.
Works With Real Workflow
Designed for appraisers already working in Excel and TOTAL, not for replacing everything they do.
The Philosophy
Most software adds more screens, more clicks, and more friction. AppraisersTech is being designed around the opposite idea: no typing, or much less typing, and as little button-pushing as possible. Wherever the workflow can intelligently carry information forward, it should.
The appraiser’s time is better spent analyzing market behavior, identifying true comparability, and supporting adjustments with evidence — not repeating the same clerical work across multiple assignments.
Many appraisers are familiar with tools like the Don Machholz 1004MC spreadsheet—powerful because they reduce repetitive analysis and make patterns easier to see.
AppraisersTech builds on that same idea, but extends it beyond a single form. Instead of supporting just the 1004MC, the workflow is designed to carry analysis, adjustments, and support across the entire report.
The goal is not just to assist with one section, but to handle the majority of the heavy lifting—so once the analysis is complete, the report is already structured, supported, and largely written.
Who It Is Being Built For
- Residential appraisers who rely on paired sales support
- Appraisers who want fewer revision requests and stronger market support
- Appraisers doing retrospective, estate, and date-of-death assignments
- Appraisers already using Excel and TOTAL in their workflow
- Appraisers who want speed without sacrificing credibility
Built by a Working Appraiser
With over 20 years of appraisal experience, the workflow behind AppraisersTech has been refined through real assignments, not theory.
AppraisersTech is being developed by James Valdez, a practicing residential appraiser. The direction of the platform comes from real assignment problems, real report writing friction, and real paired sales research — not theoretical software planning disconnected from field work.
That matters because the best appraisal tools do not start with features. They start with workflow.
