The Two-Sentence Answer
The BINSR is the Buyer's Inspection Notice & Seller's Response — the Arizona Association of REALTORS form used in Arizona resale purchase contracts to document what the buyer's inspection found and what the seller agrees (or refuses) to do about it. The buyer delivers it during the inspection period listing items they want corrected; the seller responds within 5 days by agreeing to fix, declining, or negotiating; and the buyer then has 5 days to accept the response or cancel the contract with their earnest money back.
If you inspect homes in Arizona, the BINSR is the reason your phone rings. Every resale transaction written on the standard AAR contract funnels the buyer's inspection findings through this one form, which means your report is the raw material for one of the most consequential negotiations in the deal. Understanding how the form works — and formatting your reports so agents can use them without friction — is one of the highest-leverage things an Arizona inspector can do for referrals.
Good plain-English walkthroughs of the buyer side of the process are published by AZ Mortgage Brothers, Wise Move AZ, and District Lending. This guide covers the same ground from the inspector's chair.
How the BINSR Timeline Works
The standard Arizona resale contract gives the buyer a 10-day inspection period (the parties can negotiate a different length, but 10 days is the default). Everything BINSR-related hangs off that window, followed by two 5-day response periods — the "10/5/5" flow agents talk about:
| Phase | Who Acts | Timeframe | What Happens |
|---|---|---|---|
| 1. Inspection period | Buyer | 10 days from contract acceptance (default) | Buyer completes all inspections — home inspection, termite, sewer, roof, whatever they choose — and decides how to proceed. Before the period ends, the buyer can accept the property as-is, cancel outright based on the findings, or deliver a BINSR listing the items they want corrected. |
| 2. Seller's response | Seller | 5 days after receiving the BINSR | Seller responds on the same form: agree to correct the items, decline to correct some or all of them, or propose a middle ground (a credit, a partial fix, a licensed-contractor repair). Silence is effectively a refusal. |
| 3. Buyer's election | Buyer | 5 days after the seller's response | Buyer either accepts the seller's response and moves forward, or cancels the contract and gets the earnest money back. If the seller agreed to everything requested, the deal simply proceeds. |
Two practical notes that matter to inspectors. First, the clock is short and unforgiving — a buyer who books an inspection on day 7 of a 10-day period has left their agent almost no time to read the report, decide what to ask for, and draft the BINSR. That is why Arizona agents prize inspectors with fast scheduling and same-day or next-day report delivery. Second, the BINSR is a one-shot document in most transactions: the buyer lists everything they want in a single notice, so the report it is built from needs to be complete the first time. "I'll send an addendum when the photos finish uploading" does not work inside a 10-day window.
What Inspectors Need to Know
You do not fill out the BINSR — the buyer and their agent do. But make no mistake: your report is the source document for the BINSR. When the agent sits down to draft the notice, they are working line-by-line from your findings. That has three direct consequences for how you work:
Your findings become negotiation line items. Each defect you document may turn into a repair request with real dollars attached. A finding like "water heater TPR discharge pipe terminates improperly — recommend correction by a licensed plumber" translates cleanly onto a BINSR. A finding like "some plumbing concerns noted" does not. Vague findings force the agent to either interpret (risky) or call you for clarification (slow, inside a 10-day clock).
Ambiguous reports cause repair-request fights. When the buyer's BINSR says "repair the roof per inspection report" and your report shows three photos of lifted shingles with no severity language, the seller's agent will argue it's cosmetic, the buyer's agent will argue it's a defect, and both sides will be emailing you for a ruling you never wanted to make. Clear severity language — what it is, why it matters, and what action you recommend — settles the argument before it starts.
Photos are your evidence, and the BINSR's. A seller is far more likely to agree to a correction when the request references a numbered finding with a timestamped photo than when it references a paragraph of prose. One photo per finding, tied to the finding, is the standard the BINSR process quietly demands.
How a Clean Report Makes You the Agent's Favorite Inspector
Here is the referral math most inspectors miss: the person who feels the quality of your report most acutely is not the buyer — it's the buyer's agent, at 8 PM, drafting a BINSR against a deadline. If your report has numbered findings, a defect summary up front, and a photo attached to every issue, the agent copies your language, attaches your photo references, and finishes in twenty minutes. If your report is a 60-page wall of boilerplate with findings buried in section narratives, the agent spends two hours excavating it — and remembers.
Agents in Phoenix, Tucson, and every Arizona market write BINSRs constantly. The inspector whose reports make that job easy becomes the name they hand to the next buyer, and the one after that. "BINSR-friendly reports" is genuinely a thing Arizona agents say to each other. Fast turnaround matters for the same reason: a report delivered the same evening leaves the agent days of breathing room inside the inspection period instead of hours. If you're building an Arizona practice, pairing solid inspection work with reports agents can lift straight into the BINSR is the cheapest marketing you will ever do — see our Arizona home inspection software page for how local inspectors set this up, plus market-specific notes for Phoenix and Tucson.
Report Format Tips for BINSR-Ready Reports
If you want agents to lift your findings straight into a BINSR, format for it deliberately:
- Number every finding. "Item 14: GFCI protection absent at exterior receptacles" gives the agent (and both attorneys, if it comes to that) an unambiguous reference. The BINSR can simply say "correct items 3, 7, 14, and 22 per the inspection report."
- One photo per finding, minimum. Attach the photo to the finding, not to a gallery at the end. Evidence and claim should travel together.
- Write plain-language summaries. Lead each finding with what a non-inspector can understand: what's wrong, why it matters, what should happen next. Save the code citations for the body.
- Include a defect summary section. A front-of-report summary listing only the material defects is the page agents actually work from. (Our home inspection report template guide breaks down this structure in detail.)
- State a recommended action on every defect. "Recommend evaluation and repair by a licensed electrician" is a BINSR-ready sentence. Observation without a recommended action leaves the negotiation hanging.
- Deliver fast. Same-day or next-morning delivery gives the agent room to work inside the 10-day period.
This is exactly the structure InspectorData's AI report writer produces by default: numbered, photo-attached findings with plain-language summaries and recommended-action language that agents can copy into a BINSR without rewriting.

Frequently Asked Questions
What does BINSR stand for?
BINSR stands for Buyer's Inspection Notice and Seller's Response. It is the Arizona Association of REALTORS form used in Arizona resale purchase contracts to document the buyer's inspection findings and the seller's response — fix, decline, or negotiate — during the repair-negotiation phase of the transaction.
How long does a seller have to respond to a BINSR?
Under the standard Arizona resale purchase contract, the seller has 5 days to respond to the buyer's BINSR. The seller can agree to fix the items, decline to fix them, or propose a middle-ground correction. The buyer then has 5 days to accept the seller's response or cancel the contract with their earnest money returned.
Is the BINSR required in Arizona?
The BINSR itself is not legally mandated, but it is the standard Arizona Association of REALTORS form used in virtually all AZ resale transactions written on the AAR purchase contract. A buyer is not required to deliver a BINSR — they can accept the property as-is — but if they want repairs or want to cancel over inspection findings, the BINSR is the vehicle the contract provides.
Can a buyer cancel after the BINSR?
Yes. If the seller declines to correct items listed on the BINSR (or the buyer disapproves of the seller's response), the buyer typically has 5 days to elect to cancel the contract and receive their earnest money back. The buyer can also cancel during the inspection period itself based on the inspection findings.
Does the home inspector fill out the BINSR?
No. The BINSR is completed by the buyer, usually with their real estate agent, using the inspection report as the source document. The inspector's job is to deliver a clear, well-organized report — numbered findings, photos, and plain-language summaries — that the agent can lift directly into the BINSR without interpretation fights.
