The 0–100 score
This is a comparative indicator built from price, costs, risk, condition and protection. It is not a probability of success. It works best when comparing several options using the same assumptions.
Price ceiling
The ceiling is the maximum suggested price under your benchmark, costs and risk assumptions. It should not rise merely because the seller rejected your offer.
Risk
High risk can come from missing documents, limited inspection, poor condition or pressure to decide quickly. Reduce risk with evidence first; only then compensate through price.
Verdict
The verdict is shorthand. Decide from the cost breakdown and the most sensitive assumptions, not from a colour or label alone.
