Can AI Smell Cat Urine? The Limits of Algorithmic Buying — Why Tech + Touch Wins
Computer vision can count cabinets, but it can’t smell pet odors, feel soft subfloors, or read a probate file. This is why early iBuying mispriced risk and why our Tech + Touch workflow verifies FOS before we price—so sellers see real nets, not hopeful math.
The 1-Minute Summary
- Problem: Algorithms miss real-world issues (odors, permits, title, occupancy). That’s why some iBuyers mispriced risk.
- Our fix: Tech + Touch. We use data to price quickly, then humans verify friction before you commit.
- Your takeaway: In simple, hot areas, listing can win. In complex or slow markets, verified cash often matches or beats listing net after time costs.
Fast FAQ
Will I always net more with a cash offer?
No. In hot, low-complexity pockets with strong buyer demand and clean condition, a listing can beat a cash net. We show both paths in the Unified Net Offer Sheet so you can choose with eyes open.

Plain-English Mode
Switches BDI → Buyer Demand, RCI → Complexity, FOS → Friction to Close, CoCI → Cost of Certainty.
The Cat-Urine Problem: Sensors vs. Reality
Algorithms see pixels and tables. They do not smell ammonia, hear a ticking panel, feel the faint spring in a hallway plank, or notice a barely-visible moisture shadow behind a vanity. These are hidden issues (“friction”) that widen spreads after the “instant offer.” Skip verification, and you pay later—via concessions, re-trades, or fallout.
Odors, moisture, pest activity, soft subfloor, DIY wiring.
Probate, liens, permits, HOA arrears, code issues.
Access windows, occupancy, cleanout, vendor capacity.
Local demand, block-level sentiment (HSS), shifting days-on-market bands.
Our models anticipate friction (FOS) and demand (API/HSS), but we still send humans to verify. That’s the “Touch” in Tech + Touch.
What iBuying Got Wrong
- Priced to the median, ignored variance and tail risk.
- Treated every home as an interchangeable SKU; skipped friction verification.
- Small errors multiplied across thousands of homes → system-level losses.
| Dimension | Blind iBuying | Tech + Touch (Verification) |
|---|---|---|
| Assumption | Photos & comps tell all | Some truths aren’t visible—verify |
| Pricing basis | Median comps + CV on listing photos | Local demand & complexity + verified friction → offer bands |
| Variance control | Low upfront; high after offer | Higher upfront; much lower later |
| Fall-through risk | Higher | Lower |
| Seller experience | Fast offer, slow surprises | Fast clarity, fewer surprises |
We also acknowledge when a listing wins. In hot, low-complexity pockets, a proper listing campaign can beat a cash net. See the Unified Net Offer Sheet.
Tech + Touch: The FOS Verification Loop
- Pre-underwrite access and title (data pulls + intake interview).
- Guided walkthrough with photo prompts to surface hidden issues; flag “smell/feel” items for in-person confirmation.
- Offer bands tied to milestones; if friction drops, price tightens.
- Execution windows booked in advance (vendor SLAs), compressing variance.

iBuying vs. Tech + Touch (Plain English)
Blind iBuying: assumes perfect information and frictionless execution. Looks precise. Feels fast. Breaks on contact with reality.
Tech + Touch: uses tech for speed and scope, then inserts human verification to remove unknowns that matter to price, timeline, and risk. Looks thoughtful. Feels predictable. Performs under stress.
Interactive: How Time Erodes Net
Slide the control to see how longer Days on Market typically impacts concessions, holding costs, and fallout risk. For the full model, generate your Net Offer Sheet.
Estimated concessions: $4,500 • Holding: $3,375 • Fallout EV: $2,700
Net impact vs. day-30 baseline: -$5,075

Real Cases (Anonymized)
Maricopa County • 85254
- List at $520k → 67 DOM → two cuts → $495k contract → $7.8k concessions
- Holding (67 days @ ~$95/day): ~$6.3k • One fallout (re-list 12 days)
- Final net: ~$478k after costs
Unified Net Offer Sheet showed verified-cash net at ~$476k at day 7. Seller listed and landed ~$2k higher, but with 79 days of uncertainty.
Hillsborough County • 33624
- Odor/moisture + permit closeout; API 74, HSS 0.42 (high friction)
- Verified cash at day 9: $318k net vs modeled listing net $312k (60–90 DOM)
- Outcome: chose cash due to schedule, not price.

FAQ
Is this a sales page?
It’s a working paper from our research arm with a clear conflict disclosure. We publish methods, dataset links, and cases where listing wins. We keep the main CTA at the bottom to separate research from sales.
Where can I see your methods and datasets?
Start with the Research Data Catalog & License. You’ll find method notes and downloadable CSVs (e.g., Endowment Effect summary data).
Will I always net more with a cash offer?
No. In high-BDI, low-complexity pockets, a well-run listing can beat cash. In thin-demand or high-friction cases, verified cash can compete or win on net after time, concessions, and fallout risk. Our Net Offer Sheet shows both paths side-by-side.
Can I run this model on my house?
Yes—request your side-by-side via the Unified Net Offer Sheet. We’ll calculate demand (BDI), complexity (RCI), friction (FOS), and CoCI, then show your options.
Remaining Risks & How We Mitigate Them
The issue: Even with a toggle, unfamiliar terms can slow a seller who just wants a clear number.
- Plain-English by default: We now auto-enable Plain-English on first visit (BDI → Buyer Demand, RCI → Complexity, FOS → Friction to Close, CoCI → Cost of Certainty).
- Inline tooltips & friendlier labels: “hidden issues” (not “hidden issues (“friction”)”), “probate paperwork” (not “dockets”).
- Pro mode preserved: Analysts can flip the toggle back to full terminology anytime.
The issue: If PropTechUSA.ai looks like a wrapper without real data, trust suffers.
- Live Data Catalog: Methods & Data Catalog with CSV previews and license.
- Release notes + PDFs: Each working paper links to methods PDFs and change logs.
- External advisory acknowledgment: We’ll publish named advisors upon consent (appraisal, statistics, title).
- Research vs. sales separation: CTAs live at the bottom; research flows uninterrupted.
