Material fact
The word material does not mean interesting, unpleasant, or worth gossiping about. It means important to the transaction. A strong answer asks what decision the fact could change, whether the licensee actually knows it, whether it is confidential, whether it concerns the subject property's physical condition, whether a buyer could discover it, and which relationship controls the duty.
Last updated: August 1, 2026
What does this exam area cover?
Short answer: A material fact is information significant enough to affect a reasonable transaction decision, price, terms, value, health, safety, legality, or risk. An Illinois agent discloses actually known material transaction facts to the client unless genuinely confidential. A seller's agent timely discloses actually known latent material adverse physical facts to a buyer customer when reasonably diligent inspection would not reveal them. Material physical information is not protected confidential information.
This guide follows the PSI Illinois Candidate Information Booklet effective June 24, 2026, current 225 ILCS 454/1-10, 15-15, 15-20, and 15-25, Rule 1450.810, and 765 ILCS 77, all checked through August 1, 2026. It distinguishes the broad exam concept from the narrower Illinois statutory customer rule. Federal lead, fair-housing, environmental, lending, securities, and consumer-protection laws, plus contracts and local ordinances, can impose additional disclosure or privacy duties.

Which distinctions produce the most mistakes?
- Terms
- Material fact vs. material defect
- Difference
- Material fact is any significant transaction information. Material defect is a serious adverse property condition within the governing definition.
- Question cue
- Broad important information versus serious condition.
- Terms
- Material defect vs. latent defect
- Difference
- Material describes importance. Latent describes discoverability. A condition can be either, both, or neither.
- Question cue
- Seriousness versus hidden nature.
- Terms
- Fact vs. opinion
- Difference
- Fact is objectively verifiable. Opinion is judgment or estimate and should be identified and supported rather than presented as certainty.
- Question cue
- What is versus what someone thinks.
- Terms
- Knowledge vs. rumor
- Difference
- Knowledge rests on actual awareness or reliable evidence. Rumor is unverified information that requires investigation before repetition.
- Question cue
- Established awareness versus hearsay.
- Terms
- Client duty vs. customer duty
- Difference
- The client receives known material transaction facts, subject to confidentiality. The seller's buyer customer receives known latent material adverse physical facts under the specific statutory test.
- Question cue
- Broad represented advice versus narrow opposite-party disclosure.
- Terms
- Confidential information vs. physical condition
- Difference
- Negotiating information can be protected. Material physical-condition information is expressly outside confidential information.
- Question cue
- Private strategy versus property truth.
- Terms
- Stigma vs. physical consequence
- Difference
- A nonphysical event may be protected from required disclosure. Unrepaired physical or environmental damage caused by it requires separate analysis.
- Question cue
- History versus present condition.
- Terms
- On-site vs. off-site condition
- Difference
- The subject property's physical condition falls within direct duties. An off-site condition receives the statutory substantial-adverse-value test and fact-specific review.
- Question cue
- Subject property versus neighboring property.
- Terms
- Disclosure vs. diagnosis
- Difference
- Disclosure communicates a known fact. Diagnosis determines technical cause, severity, remedy, or legal effect and belongs to a qualified expert.
- Question cue
- Report what is known versus practice another profession.
- Terms
- Seller report vs. broker statement
- Difference
- The seller report records seller knowledge on the statutory form. A broker disclosure fulfills the licensee's independent duty based on broker knowledge.
- Question cue
- Owner's form versus licensee's obligation.
The F-A-C-T-S check
- Fact: state the exact verified information, its source, date, property or transaction connection, and whether it is a physical condition, legal issue, economic fact, or nonphysical event.
- Audience and agency: identify the client, customer, opposite party, and licensee role, then apply the broad client rule or the narrower seller-licensee customer rule.
- Consequence: test whether the fact could reasonably affect decision, price, terms, value, use, health, safety, legality, income, cost, or risk and whether it is adverse.
- Transparency limits: protect true client confidentiality, but do not conceal material physical information; apply stigma and off-site protections carefully and avoid rumor or steering.
- Share and support: disclose timely and accurately when required, preserve proof, correct misinformation, recommend the proper expert, and keep seller, broker, inspection, contract, and statutory disclosures separate.

How do the rules work in scenarios?
Known zoning violation
Scenario: A buyer's agent receives a municipal notice showing that the client's intended apartment use violates current zoning. The building itself has no physical defect.
- The official notice is reliable transaction information.
- Permitted use is central to the buyer's decision and value analysis.
- A material fact need not be a physical defect.
Answer: The buyer's agent should promptly disclose the known material transaction fact to the client and recommend legal and zoning review.
Seller calls seepage confidential
Scenario: A seller privately tells the listing agent about recurring concealed foundation seepage and instructs the agent to keep it confidential.
- The condition concerns the property's physical state.
- Material physical-condition information is not confidential under the Act.
- The hidden, adverse condition falls within the customer disclosure analysis.
Answer: The instruction does not authorize concealment; the licensee must follow disclosure law and sponsor direction.
Visible broken window
Scenario: A buyer sees and photographs a large broken front window during a showing. The listing agent is asked whether it is latent.
- The condition is plainly visible.
- A reasonably diligent inspection would discover it.
- Visibility does not decide materiality, but it defeats latency on these facts.
Answer: It is patent rather than latent, though it may still affect price, repair, safety, and contract terms.
Prior death with no physical effect
Scenario: A natural death occurred in a house years earlier and had no effect on the property, environment, or structures. A licensee does not volunteer the history.
- The fact concerns a nonphysical occurrence.
- Section 15-20 protects failure to disclose such an event.
- Medical and personal privacy remain relevant.
Answer: The licensee is not required by this Illinois rule to volunteer the nonphysical history.
Fire history and current damage
Scenario: A fire occurred in the property. The event itself is old, but the listing agent knows hidden structural charring remains unrepaired behind new wallboard.
- The current concealed structural condition is physical.
- It is adverse, potentially material, and not discoverable by ordinary viewing.
- The event protection does not erase present damage.
Answer: The known latent physical condition requires timely disclosure and expert evaluation.
Customer supplied false information
Scenario: A customer gives a buyer's agent an inaccurate statement. Before forwarding it, the agent obtains a public record proving the statement false but sends it unchanged.
- The licensee now knows the information is false.
- The source is not a shield after contrary knowledge arises.
- Negligent and knowing misrepresentation rules remain relevant.
Answer: The licensee must not repeat the false statement and should correct the record accurately.
Nearby condition without value effect
Scenario: A licensee learns of a minor physical issue on a property several blocks away that has no substantial adverse effect on the subject property's value.
- The condition is located off site.
- The facts establish no substantial adverse value effect.
- Section 15-20 protects failure to disclose that category.
Answer: The licensee has no disclosure liability under that statutory category for withholding it.

Questions students ask about Material Fact: Illinois Real Estate Exam Guide
What is a material fact in real estate?
A material fact is information important enough to influence a reasonable person's decision, price, terms, risk assessment, or willingness to proceed with a transaction. It is broader than a physical defect. Depending on the facts, material information can concern condition, title, access, legality, income, leases, boundaries, environmental risk, or another transaction issue. The exact Illinois disclosure duty depends on whom the licensee represents and what the licensee actually knows.
What material facts must an Illinois agent disclose to a client?
Section 15-15 requires a licensee representing a client to disclose material facts concerning the transaction that the licensee actually knows, unless the information is confidential. The same section preserves common-law duties concerning negligent or fraudulent misrepresentation of material information. A licensee should not guess, exaggerate, or hide behind a narrow property-condition form.
What material facts must a seller's agent disclose to a buyer customer?
Section 15-25 requires timely disclosure to a prospective buyer customer of actually known latent material adverse facts about the property's physical condition that the customer could not discover through a reasonably diligent inspection. The seller's agent must also treat the customer honestly and must not negligently or knowingly provide false information.
Is every material fact a material defect?
No. Material fact is the broader category. A material defect is a serious adverse condition, commonly physical, that substantially affects value or significantly affects health or safety under the Illinois seller-report definition. A known zoning violation, unrecorded access problem, false rent roll, or disputed ownership interest can be material to a transaction without being a cracked foundation or failed furnace.
Can a seller call a physical defect confidential?
No. The Real Estate License Act's definition says confidential information does not include material information about the property's physical condition. A client instruction to conceal a material physical condition does not convert it into a protected negotiating secret. The licensee should disclose as required, refuse unlawful concealment, document the issue, and involve the sponsoring broker and counsel when necessary.
Are murder or suicide material facts in Illinois real estate?
Illinois law protects a licensee from a cause of action for failing to disclose an act or occurrence at the property that had no effect on its physical condition, environment, or structures. Rule 1450.810 lists murder and suicide as examples. If the event caused physical or environmental damage, that resulting condition must be analyzed separately. Never invent, confirm, or spread private information without a lawful basis.
Must a licensee disclose an occupant's medical condition?
Section 15-20 provides that no cause of action arises against a licensee for failure to disclose that an occupant had HIV or another medical condition. Treat medical information as private and follow fair-housing and civil-rights law. A property condition that independently affects health or safety, such as contamination, is analyzed on its own facts rather than by the occupant's diagnosis.
Are neighborhood facts always material?
No. Section 15-20 protects failure to disclose fact situations on property that is not the transaction subject and physical conditions on other property that do not substantially adversely affect the subject property's value. A nearby physical condition that does have a substantial adverse value effect may require different analysis. Verify through reliable sources and avoid steering or subjective neighborhood characterizations.
Does actual knowledge allow a broker to ignore obvious warning signs?
No. Actual knowledge is central to several statutory disclosure duties, but a licensee must still use reasonable skill and care, treat customers honestly, and avoid negligent or fraudulent misrepresentation. The licensee should not diagnose beyond competence, yet should investigate records within the brokerage role, ask focused questions, recommend qualified experts, and avoid repeating information the licensee knows or should know is false.
Does the seller's disclosure report replace broker disclosure?
No. The seller's statutory report records the covered seller's actual knowledge. The licensee's duties arise separately under the Real Estate License Act and common law. A seller's no answer does not authorize the listing agent to suppress a latent material physical fact the agent actually knows. The buyer's inspection, contract, and specialized statutory disclosures are separate again.
Are these official PSI questions or legal advice?
No. The practice questions are original. The PSI Illinois outline, Real Estate License Act, Rule 1450.810, and Residential Real Property Disclosure Act were checked through August 1, 2026. This is exam education, not legal, inspection, engineering, environmental, privacy, fair-housing, fraud, title, zoning, or transaction advice. A live fact requires source verification, agency status, actual-knowledge evidence, confidentiality analysis, materiality, visibility, expert review, written disclosure, and sponsor or counsel direction.
