The Property Auction: Before You Bid - Red Flag, Quick Reference

The Property Red Flag Quick Reference: Your 60-Second Triage Card

In the heat of a viewing, don't let emotion override engineering. Carry the answers in your pocket.

This double-sided "Quick Reference" card is the distilled essence of a Senior Structural Engineer’s diagnostic process. It is designed to be printed, laminated, and carried to every property viewing, providing instant clarity when you spot a defect.

Side A: The Six Flags to Walk

The "Fatal" bucket in one list. If any of these six items are present, the advice is simple: Stop. Do not fall in love. Walk away.

• Active Subsidence: Recognizing the classic "bay corner" step crack and tree influence.

• Japanese Knotweed: Identifying the "finance killer" without a management plan.

• and more

Side B: Price & Decide

The "Structural Triage" system for everything else. Turn defects into line items using the P/N/D method:

• Priceable (P): Well-understood defects you can budget for, fix, and move on from.

• Negotiable (N): Priceable issues that scare other buyers—giving you the perfect lever for a price reduction.

• Deal-Breaker (D): Issues that cannot be priced with confidence.

Instant UK Costing Ranges:

Includes a high-speed reference for typical repair costs, including:

• Re-roofing, rewiring, and heating upgrades.

• Wall tie replacement and chemical damp-proof courses (DPC).

• Asbestos removal and plastering.

• The 20% Contingency Rule: Why you must pad your budget more than standard stock.

"The cheapest house is the one you didn't buy." This card ensures you never overpay for a problem you can’t solve.
