Signals that strengthen a negotiation

- Several price drops over time.
- Long observed exposure with little movement.
- Current price above the local market reference.
- Reactivation or republication signals that suggest the listing is not truly new.
How to prepare the offer
Use the data to define a range, not just a single number.

- Use price drops and time on market as arguments.
- Avoid assuming the seller is flexible without corroborating signals.
