- Today - Person offers $100/point, goes through ROFR, buyer gets points
- 12 months - Person offers $100/point, goes through ROFR, Disney takes contract
- Same Day - Broker tells new sellers to increase listing price / tells buyers about ROFR on $100/point offers
- Next Day - Person offers $105/point, goes through ROFR, buyer gets points
This is a single example of the basic workings on how pricing can go up. In addition people want to get the most they can for the contract. If a contract is not selling after 15-30 days you are more likely to decrease your price if in your mind you still make a profit.
Someone on the flip side that paid $100/point and now can only sell something for $80/point is more likely to hold out longer for a higher sale price because there is an incorrect attachment to the price they had paid in the past.
