Overall score
#3 of 22 similar
S and Z Property Brothers has a strong overall score. It ranks 3rd out of the 22 Illinois cash home buyers we’ve scored. Excellent customer ratings are backed by a deep review history — 181 ratings averaging 4.9 stars. Recent review activity is limited, with only 2 reviews in the past 6 months. That’s too little feedback to establish a recent rating trend. It has strong business credentials, including enhanced screening with our team.

Customer experience
Top 5% in IL
S and Z Property Brothers has a strong customer experience profile. Its substantial review record was overwhelmingly positive. The latest 3 months contained 1 5-star rating — just 1 rating, too few to establish a sustained trend. Its Customer Experience score of 94/100 places it around the top 1% of comparable cash buyers serving a single market.
Lifetime ratings. Lifetime feedback was strongly positive: 181 rated reviews averaged 4.9/5, with 177 five-star ratings and 2 one-star ratings. Reviews dated back to 2021. Our methodology adjusts small rating samples toward the typical company rating, then maps the adjusted rating to a score and applies a small review-depth deduction that decreases as the record grows. Volume credit grows with every rating, with an additional small adjustment that grows fastest over the first few hundred ratings and then slows. It strengthens the distance from the neutral, sample-adjusted 4.5-star signal; this record received a 0.71% adjustment to that signal. This added 0.17 score points before the depth deduction and confidence limit.
Recent ratings. The latest 12 months contained 5 ratings averaging 5.0/5. The latest 6 months contained 2 5-star ratings. The latest 3 months contained 1 5-star rating, through October 31, 2026.
Rating trends. Ratings improved slightly from an already strong lifetime average. The 3-month average rose from 4.94 lifetime to 5.00 — up 0.06 stars, or 1.1%. The five-star share rose from 97.8% to 100.0%, up 2.2 percentage points. The recent sample contained just 1 five-star rating. It was too small to establish a lasting improvement.
Common themes. A smooth process led the feedback, appearing in 54 of 80 detailed customer reviews (68%), followed by compassionate treatment in 22 (28%). Other common themes — fast closings, honesty and transparency, and knowledge and capability — each appeared in 21 (26%). Reviews could mention multiple themes.
Review relevance. We classified 108 of 181 reviews (60%) as relevant to the home-selling experience. Another 29 concerned property buyers, other products or services, business partners and initial contacts without reported outcomes. The remaining 44 reviews had too little text to analyze. All 181 star ratings remained in the lifetime rating record.

How we researched and scored this company
Methodology
We research each company using its website, business profiles, and third-party customer reviews. We use company sources to understand its services and terms, and distinguish those claims from independent evidence. When available, we also draw on interviews with company representatives and sellers, and relevant public records.
When there is enough evidence, we calculate an overall score out of 100 using 3 categories:
- Customer experience (67.5%) reflects customer satisfaction, based primarily on average customer ratings and the number of reviews supporting them.
- Recent activity (20%) reflects recent review volume, how recently the company received a review, and how its recent review pace compares with its history. Reviews are a signal of activity, not a count of completed home purchases.
- Credibility (12.5%) considers business verification, website transparency, public engagement, and documented operating history.
Use the company or location identified on this page when interpreting the evidence. A broader company record may not describe every local office. Review history is separate from the company’s founding date.
Limited evidence can restrict what we can assess. A company may appear without a score, and a small review sample may not represent a typical seller’s experience. Scores summarize the evidence available to us; they do not predict an offer price or guarantee a sale or service quality.
