One portfolio.
A clearer order of priorities.
A collection of tax bills is only the starting point. We help you determine which properties deserve attention and what to do next.
01 /
Find the properties worth reviewing.
Bring addresses or PINs. We organize the portfolio and examine assessments, sales, and appeal history where records are available.
02 /
Prioritize with evidence.
Separate opportunities from open questions. Understand the valuation issue, the supporting records, and the information still needed.
03 /
Move forward with a clear plan.
Agree on scope, fees, responsibilities, and timing before work begins. Keep the next step visible for each property.
A portfolio, brought into focus.
Your properties. One organized review.

Example workflow. County coverage and records are confirmed during review.
Start with the properties you own. Build the plan around what the evidence shows.
Bring the whole list
Have a portfolio spreadsheet?
Start there.
Use the list you already maintain. Request a review, then attach your spreadsheet to the email draft. We’ll confirm coverage and scope before analysis begins.
A useful starting list
- Property addresses or PINs
- County and property type
- Ownership groups, if relevant
- Questions or known assessment issues
One property per row. An existing Excel or CSV file is fine. Initial lists should exclude tenant details and confidential financial records.
Your assessment deserves a closer look
The tax bill is the result.
The evidence is where we start.
A high bill alone does not establish an appeal. We examine the assessment, the property, and the available market evidence to see what supports a closer review.
PROPERTYWhat do you own?
Confirm the parcels, property type, and assessment context.
EVIDENCEWhat does it show?
Examine relevant records, sales, and valuation assumptions.
DECISIONWhere should you act?

Who we serve
Different properties.
One clear place to start.
For the people who own, manage, and make decisions about real estate. Portfolio review is our focus, with room to start at any scale.
Property management companies
Give owners a clearer picture of their assessments. Coordinate property lists, missing records, and recommended next steps across the assets you manage.
Single-family rental portfolios
Bring scattered addresses into one review. Look for assessment questions across the rental portfolio while keeping each property’s evidence distinct.
Condominium associations
Start with the building and its units. Help boards and managers organize parcel information, understand assessment patterns, and identify what needs closer review.
Commercial properties
Office, retail, and mixed-use assets. Examine the assessment alongside the property’s characteristics and available sales or operating information.
Multifamily properties
From individual apartment buildings to a collection of assets. Review the valuation assumptions and the records needed to assess each property.
Industrial properties
Warehouses, distribution, and manufacturing properties. Consider use, size, condition, and relevant market evidence in the assessment review.
Individual homeowners
One home deserves a clear explanation, too. Start with an address or PIN and discuss whether the assessment warrants further analysis.
Cook County and surrounding Illinois counties. We confirm coverage, available records, and the scope of work for each property before engagement.
Start with an address
One address.
Start there.
Request a free preliminary property review. We’ll look at the available information and discuss whether a deeper analysis makes sense.
No portfolio is too complicated to start with a conversation. If you own several properties, share the full list.

Straight answers
A few things
you might be asking.
Property taxes are complicated.
Getting started should feel simple.
Can you review an entire portfolio?
That is the focus. Start with addresses or PINs and a brief description of the portfolio. We confirm county coverage, available records, and scope before proceeding. Use the review form to tell us the portfolio size and property types. You can attach an existing spreadsheet when you send the email draft.
Can I start with just one property?
Yes. Enter an address or parcel number in the property-review form. It carries into your request so you can ask for a free preliminary review without assembling a full portfolio first.
What does AppealZoo® do?
AppealZoo® supplies the property research technology behind the consulting workflow. Tax Appeal Tech applies that research to the properties being reviewed, with practitioner judgment and source verification.
How is my property reviewed?
Our team reviews the property information, assessment, and available market evidence. We discuss what supports further analysis and what additional records may be needed. The sample report shows the format; its figures are hypothetical.
What does it cost, and when am I committed?
The preliminary property review is free. Any paid work requires a written engagement that establishes the scope, fees, responsibilities, and terms. Sending an inquiry does not sign you up or create a payment obligation.
Does an estimated opportunity guarantee savings?
No. An estimate is a scenario based on stated assumptions. Records, valuation evidence, applicable procedures, and the final assessment all matter. We distinguish potential savings from actual results.
